TREES AND SHRUBS OF MEXICO. 


ADVERTISEMENT. 


The United States National Herbarium, which was founded by the 
Smithsonian Institution, was transferred in the year 1868 to the 
Department of Agriculture and continued to be maintained by that 
department until July 1, 1896, when it was returned to the official 
custody of the Smithsonian Institution. The Department of Agri- 
culture, however, continued to publish the series of botanical reports 
entitled “Contributions from the United States National Herba- 
rium,’”’ which it had begun in the year 1890, until on July 1, 1902, 
the National Museum, in pursuance of an act of Congress, assumed 
responsibility for the publication. The first seven volumes of the 
series were issued by the Department of Agriculture.

PREFACE. 


The present volume consists of an account of the trees and shrubs 
of Mexico, by Mr. Paul C. Standley, Associate Curator of the United 
States National Herbarium. The work is based wholly upon the 
extensive series of Mexican plants in the National Herbarium, a 
large proportion of which have been obtained by special investigators 
sent out by the United States National Museum and the United 

States Department of Agriculture. The flora of Mexico, especially 

the arborescent flora, includes many species of great economic value. 
They furnish many products of commercial importance, such as 
henequen and ixtle fiber, palm oil, lumber, cacao, rubber, drugs, 
alcohol, and many fruits. 

Heretofore no descriptive flora of any portion of tropical conti- 
nental North America has been published, and the identification of 
the species of plants yielding important products has often been 
very difficult. Identification of material has been possible only by 
comparison with extensive series of herbarium specimens, such as 
are to be found only in the larger botanical institutions, or by reference 
to isolated descriptions, many of them available only in the largest 
libraries. The present work brings together all the published species 
of woody Mexican plants and furnishes keys for their identification 
as well as brief descriptive notes. Much information is presented 
also concerning commercial and local uses of the plants. The ver- 
nacular names of the trees and shrubs are given, and since these are 
fairly well standardized by local usage they will be found helpful as 
guides to the identity of fragmentary or otherwise difficult material. 

Several collaborators have aided in the preparation of this volume 
by contributing the accounts of certain groups in which they are 
particularly interested, as follows: Dr. William R. Maxon, Gleichen- 
iaceae and Cyatheaceae; Dr. A. S. Hitchcock, Poaceae; Dr. William 
Trelease, Agave and Quercus; Dr. S. F. Blake, Meliaceae, Polyga- 
laceae, Violaceae, and Asteraceae; Mr. Ellsworth P. Killip, Passi- 
floraceae; Dr. N. L. Britton and Dr. J. N. Rose, Cactaceae; Dr. B. L. 
Robinson, Eupatorium and Ophryosporus; Dr. J. M. Greenman,

TREES AND SHRUBS OF MEXICO. 


By Paut C. STANDLEY. 


INTRODUCTION. 


The most interesting regions of the earth from a botanical stand- 
point are those which possess a tropical climate. There physical 
conditions are most favorable for the growth of plants, and not only 
is vegetation much more luxuriant than in temperate countries, but 
the number of species, especially of trees and shrubs, is vastly greater. 
West Virginia and Costa Rica, for instance, are temperate and tropi- 
cal areas of approximately equal size; but only 1,600 species of ferns 
and flowering plants are known from West Virginia, while the flora 
of Costa Rica includes more than three times and probably four 
times that number. Large areas in Mexico are neither tropical nor 
even subtropical, but no region of the globe, probably, possesses a 
richer or more interesting flora. Mexico has an area of 767,000 
square miles, which, although only about one-fifth that of the United 
States, exhibits a greater range of climatic conditions. The extremes 
of elevation much exceed those of the United States, ranging from 
sea level to over 5,200 meters. Almost every conceivable plant forma- 
tion is represented—the wet tropical forests of the southern lowlands, 
the temperate deciduous and coniferous forests of the central plateau 
and of the ranges of the Sierra Madre, the alpine zones of the high 
peaks like Orizaba, Popocatepetl, and Ixtaccihuatl, and the great 
barren or cactus deserts which reach their best development in the 
northern states. 

The botanical features of Mexico have attracted attention from the 
days of the earliest explorers. Many botanists have visited the 
country in the last hundred years, yet the flora is still but imper- 
fectly known. Almost every collector at the present day makes dis- 
coveries of remarkable species previously unknown to science, and 
some plants are still unknown botanically although their supposed 
medicinal properties, or their products, such as fruit, lumber, fiber. 
and gum, are well known locally and are frequently even of com- .

mercial importance. In the immense mountain ranges there are 
hundreds of difficult peaks and almost inaccessible canyons whose ex- 
ploration is extremely tedious: in the south the tropical forests are 
penetrated with difficulty, and the lofty branches of their trees are 
almost inaccessible to the collector; away from the Sierra Madre are 
innumerable isolated masses of mountains and hills, still unvisited 
by a botanist, which must yield a host of localized species. Con- 
sider, in addition, the fact that Mexico is still very imperfectly sup- 
plied with transportation facilities and it becomes evident that many 
years must elapse before a comprehensive knowledge of the flora is 
possible. 

It is unfortunate, and at the same time remarkable, that no flora 
of any part of tropical continental North America has ever been pre- 
pared. Indeed, in this respect all of North America has made little 
progress as compared with Europe, some parts of Asia, Australia, 
and Africa, or even South America. The flora of tropical Africa, 
the most recent of all the great regions of the earth to be explored by 
European peoples, has been adequately treated in botanical litera- 
ture; and the flora of Brazil has been described in a monumental 
series of volumes, of which any country might well be proud, but 
whose equal no other country possesses. For no political unit of 
North America has a modern descriptive or even a synoptical flora 
ever been published. 

The only publication approaching a flora of Mexico which has 
ever been completed is the Botany of the Biologia Centrali-Ameri- 
cana, compiled by Hemsley and issued from 1879 to 1888. This, 
though including no descriptive notes (except incidentally) nor any 
means of identifying the species, is a comprehensive work, listing all 
the species of the higher plants known at that time from Mexico 
(excluding Baja California) and Central America. Ranges and 
definite localities are given for all the species, together with the more 
important synonymy. It is superflous to state that after almost 40 
years this work has lost much of its former usefulness, as a result 
of recent botanical discoveries. Nevertheless the five volumes of the 
Biologia will always remain an invaluable and classic work upon 
tropical American plants. 

Botanical exploration in Mexico has now progressed to the point 
where a descriptive flora of the region is practicable, and such a com- 
pilation is urgently needed. The work here offered is intended to in- 
clude a complete list of the woody plants known from Mexico, with 
keys for their determination. This arbitrary and artificial division 
of the Mexican flora was chosen for treatment because it contains 
those species which are the most conspicuous elements of the vegeta- 
tion, as well as those which are of most importance from an economic 
standpoint. It includes, moreover, the larger portion of the Mexican 


STANDLEY—TREES AND SHRUBS OF MEXICO. 3 


species. Later, it is to be hoped, someone else may have an oppor- 
tunity to treat at length the herbaceous species or the flora as a whole. 
While it is only too evident that the available collections of Mexican 
plants are inadequate to furnish a complete illustration of the flora 
of the country, the offering of such a work as can be prepared with 
the material at hand needs no apology, for it is certain that the 
larger part of thé woody plants, and especially those of economic 
importance, have already been collected. 

It is not deemed advisable to include in the present publication an 
account of the general features of the flora. These have already been 
dealt with at length by other authors, particularly Hemsley? and 
Ramirez.” 


PLAN OF THE WORK. 
COLLECTIONS STUDIED. 


In this list of Mexican plants it is intended, of course, to account 
for all the trees and shrubs which have been collected in Mexico 
or reported from that country. The account is based wholly upon 
the collections.in the United States National Herbarium, although 
the published species not represented there have been included in 
the keys when possible. The National Herbarium contains the 
largest and most complete representation of Mexican plants that 
has been assembled, a large proportion of the material having been 
obtained by special collectors sent into the field by the United States 
National Museum and the United States Department of Agriculture. 
In addition, the herbarium contains many collections received from 
other institutions and individuals, the more important of which were 
obtained by the following collectors: F. Altamirano, F. W. Anthony, 
_ Brother G. Arséne, J. L. Berlandier, M. Botteri, M. Bourgeau, T. S. 
Brandegee, G. N. Collins, C. Conzatti, O. F. Cook, F. V. Coville,

Here he was associated with Botteri, and his collection numbers, in some cases 
at least, are the same as Botteri’s. His collections are in the United States 
National Herbarium. Dr. Mohr is best known for his “ Plant Life of Alabama,” 
published as volume 6 of the Contributions from the United States National 
Herbarium.

SPECIES INCLUDED. 


It is manifest that the group here chosen for treatment is an 
artificial one. It is impossible to draw a sharp line between the 
woody and herbaceous plants, although in the vast majority of cases 
such a classification is easily made. Many truly woody plants are 
so small that they are not looked upon commonly as shrubs, and 
many herbaceous plants become so large as to remind one of small 
trees. Plants which are essentially annuals, and which in regions 
where freezing temperatures occur never live more than one season, 
may in tropical regions develop more or less woody stems. More- 
over, in herbarium specimens, which as a rule consist merely of 
terminal portions of branches, it is often impossible to conclude that 
a plant is a shrub except from analogy or from information fur- 
nished by collectors. The writer would have preferred to treat 
only of the trees of Mexico, which are far less numerous than the 
shrubs and would have required less space for their elaboration: 
but the separation in the herbarium of trees and shrubs involves still 
greater difficulties than the separation of woody and herbaceous 
plants. We have so little published information regarding the size 
of Mexican plants, and most collectors show such an aversion to 
furnishing notes concerning their collections, that the classification 
of woody plants as trees and shrubs is evidently quite impracticable 
with our present knowledge. The writer’s policy as to the species 
to be included has been a liberal one, and although it is possible that 
some species have been omitted which should have been included. 
it is certain that their number is small. On the other hand, many 
species have probably been included which should have been omitted, 
but this fact will increase rather than detract from the usefulness 
of the work. Some species have been listed as shrubs, rather against 
the judgment of the writer, because of data reported by collectors. 

The statements given here concerning size are the best that can 
be compiled from published notes and from information furnished 
by collectors’ labels. The information available is not so complete 
as is desirable and in some cases may be misleading. It has not 
been the intention to publish a descriptive manual, and the brief 
descriptive notes given under most of the species are intended merely 
to supplement the keys and to indicate the most striking features of 
each species. Keys are given for the determination of genera and 


STANDLEY—TREES AND SHRUBS OF MEXICO. 5 


species and one for the determination of families. The last is 
adapted from a key to the families of tropical American plants pub- 
lished recently by Mr. Henry Pittier.t. It is very difficult, if not im- 
possible, to prepare a key to the families of tropical plants which 
will enable one always to refer a plant to its family, because many 
of the plants are still imperfectly known, and because there are in 
some families many exceptions to the typical plan of organization 
of the group. With complete material of a given plant, however 
it is hoped that the present key will usually be adequate for indicat- 
ing its family position. 

It has been intended to give references to the names of all woody 
plants published or reported from Mexico, disregarding, however, 
certain obviously incorrect names which have not received notice in 
more recent or important works. Casual references are made in 
addition to the more common cultivated exotic species. Published 
names not illustrated by material examined by the writer or not 
identifiable from the descriptions accompanying them have been 
listed as “ doubtful species” at the end of their respective genera. 
The plan has been to list as a valid species or as a synonym each 
specific name based upon Mexican material, but it has not been 
deemed necessary to list all the combinations under various genera, 
unless their citation seemed to serve some useful purpose. The writer 
has not attempted to classify all the names of Mocifo and Sessé, 
which occur in their Plantae Novae Hispaniae and Flora Mexicana, 
for these names have justly received little attention from taxonomists, 
and their determination would require an amount of labor quite 
inconsistent with any advantage that would result. Some of these 
names, however, have been referred to in their proper places. A 
very few of Mocifo and Sessé’s names are valid, but it is only by 
accident that such is the case. 


RANGES OF THE SPECIES. 


The range in Mexico ascribed to each species is based chiefly upon 
material in the National Herbarium, but reliable published reports 
have been taken into account when they indicated noteworthy ex- 
tensions of range. It is probable that in many cases the species have 
wider ranges than is indicated, but the limits of distribution can 
not be determined definitely until more extensive explorations have 
been carried out. Much more comprehensive collections are needed 
from all parts of Mexico, but especially from the states of Tabasco, 
Michoacin, Guerrero, Oaxaca, and Chiapas. Those available from

partes adyacentes de la América Tropical. Pp. 1-108. Caracas, 1917.

Tabasco and Chiapas are particularly inadequate, and doubtless 
many of the listed species occur there, even if the ranges as here 
stated do not indicate the fact. If a species occurs in Oaxaca and 
also in Guatemala, it may safely be assumed that it is found in 
Chiapas, although the writer has not felt at liberty to report its 
occurrence there unless he has actually seen specimens from that 
State. The range outside Mexico is given for those species which 
extend into other countries, and when no such range is indicated it 
is to be assumed that the species is endemic. 


TYPE LOCALITIES. 


For the majority of the species there has been included a statement 
concerning the type or the type locality. The nomenclatorial type 
of a species is the specimen which served as the basis of the origi- 
nal description of the species, and the type locality is the one at 
which the specimen was collected. A knowledge of type localities 
is of great importance in taxonomic work, especially when it becomes 
necessary to divide into two or more species material which has been 
referred previously to a single one. It is of interest also to collectors 
who may visit these places and who may take an interest in recollect- 
ing such plants at their original stations. It is to be expected, gen- 
erally, that the form of a species occurring in the region of the type 
locality is the typical one. In the case of many species described 
from Mexico, particularly the earlier ones, the source of the speci- 
mens on which they were based was given merely as “ Mexico,” with- 
out indication of any precise locality. In such instances the writer 
has made no reference to the type locality, which is, of course, prac- 
tically unknown. Neither has it seemed worth while to refer to the 
type locality in the case of species described from “tropical 
America,” “ West Indies,” or other similarly vague regions. 


VERNACULAR NAMES. 


The vernacular names listed have been gathered from various 
sources. Many have been taken from the labels accompanying her- 
barium specimens. AI] those found in literature which has come to 
the writer’s attention have been listed if there was reason to suppose 
them accurate. The most extensive work dealing with Mexican ver- 
nacular plant names is the “Sinonimia vulgar y cientifica de las 
plantas Mexicanas,” compiled by Dr. José Ramirez, with the assist- 
ance of Senor Gabriel V. Alcocer, published in the City of Mexico 
in 1902. This is a very extensive list and a valuable one, based 
partly upon the investigations of the authors, and also upon many 
previously published lists. It is unfortunate that many of the Latin 


STANDLEY—TREES AND SHRUBS OF MEXICO. | 


names are obviously erroneous and others doubtful, but the same 
statements are likely to be true of most lists of similar nature. The 
present writer is under particular obligations to Dr. Blas P. Reko, 
who has kindly permitted the use of a very extensive list of the ver 
nacular names current in Oaxaca, which he has compiled. Valued 
assistance has been rendered likewise by Dr. Alfonso Herrera, Di- 
rector de Estudios Biolégicos, of the Mexican Government. 

The names applied to plants vary greatly in different parts of 
Mexico, largely because of the diverse languages which preceded 
Spanish in different parts of the country, and which are still spoken 
in many regions, notwithstanding that Spanish is the language used 
by the great majority of the inhabitants. The Spanish names are 
the most generally used, as a rule. Many of them date back to the 
time of the Conquest, and are the same as names in common use 
for Spanish plants of more or less similar aspect, although often of 
no close relationship. In many instances the Carib names of West 
Indian plants were brought to Mexico by the early explorers and ap- 
plied to the same or similar plants growing in the latter region. In 
the case of plants first discovered in Mexico, and quite unlike any- 
thing previously known to them, the Spaniards aften adopted the 
native Mexican names, especially those of Nahuatl origin. It is in- 
teresting to observe how generally some of the Nahuatl names—often 
greatly modified in spelling and pronunciation, it is true—are now 
used among the Spanish-speaking people of North America, often 
in regions far remote from those where the Nahuatl language was 
ever spoken. Many of them are in common use among the Spanish- 
speaking people of Arizona and New Mexico, and some, like “mes- 
quite,” have become recognized English words. 

A large number of Nahuatl plant names are known, and many are 
listed here. Many more have been reported—particularly by Her- 
nandez—whose application is obscure or unknown. The Nahuatl 
language was the one spoken at the time of the Conquest by the 
inhabitants of the Valley of Mexico. The people of this prosperous 
region possessed a great love for flowers as objects of admiration and 
adornment, and were familiar with the properties and uses of many 
plants, consequently their botanical vocabulary was a remarkably 
large one. Less is known of the plant names of other parts of Mexico. 
Many names are known, however, from the Maya, which is the origi- 
nal and more or less current language of the Yucatan Peninsula 
and adjacent regions. Some names are available, also, from the 
Tarascan language of Michoacan; the Otomi, of north-central Mex- 
ico; and the Mixtec and Zapotec, of Oaxaca and Chiapas. Besides 
the vernacular names employed in Mexico, the writer has listed those 
from Central America, Colombia, and Venezuela, and from those 
islands of the West Indies in which Spanish is spoken, excluding, so

far as possible, those of local native dialects. The importance of 
recording native names can not be urged too strongly upon collectors. 
These names are often used very uniformly over wide areas and are, 
on the whole, probably better standardized than the English names 
employed in the United States. This is perhaps not remarkable, in 
view of the fact that many of the Spanish names have been in use 
for four centuries, and the native names much longer. 

The vernacular names here cited are followed by parentheses in 
which are listed the states or countries in which they are known or 
reported to be used. If there is no further comment or indication, 
it may be assumed that the names are correctly applied. In many 
cases the vernacular names have been reported by a single authority, 
and in some cases the propriety of their application is doubtful; in 
such instances the vernacular name is followed by the name of the 
authority (in italics) to whom the writer is indebted for it. 


ECONOMIC NOTES. 


The economic notes also have been gathered from a wide variety of 
sources. A large amount of information concerning the uses of 
plants has been published in Mexico, and these data have been used 
freely. References have been given to the uses made of the plants in 
other regions, particularly Central America and the West Indies. 
Some of the information here presented is taken from the published 
and unpublished notes of Dr. Edward Palmer, who was engaged for 
many years in the botanical exploration of Mexico and made ex- 
tensive observations on the local uses of plants. The Mexican flora 
contains a very large number of species of economic value, some of 
which, like the cacao and Mexican rubber tree, are of great com- 
mercial importance. The number of plants which yield edible fruit 
is very large. It would seem, also, that almost every species is em- 
ployed locally for medicinal purposes, but too much importance 
should not be attached to the data reported regarding such uses, for, 
although many of the plants do possess therapeutic properties, in the 
far greater majority of cases the properties attributed are chiefly or 
wholly fictitious. 

The Republic of Mexico, the region which is covered by the pres- 
ent work, is not a natural phytogeographic area, its boundaries 
being nowhere coincident with those of any limit of vegetation. It 
would be very difficult to draw a natural boundary along the north- 
ern frontier, and equally so on the south. There is no sharp break 
in the continuity of specific distribution on the south until the 
Isthmus of Panama is reached, and even here the break is not too 
pronounced, for a large number of species of woody plants are 
known to range from the arid regions of Colombia and Venezuela

to the similar arid areas of western Mexico. It would have been 
desirable to extend the scope of the present work to include Central 
America, but such an extension would have doubled, probably, the 
number of species treated. As the work now stands, it will be 
found useful for determination of a large proportion of the species 
native to Central America, as well as of those occurring in the 
United States in the region of the Mexican border. 

To facilitate more thorough taxonomic study of the groups here 
treated, there have been listed, when practicable, references to 
monographic accounts of each family or genus, in which there will 
generally be found complete descriptions of the species. In most 
cases only the most recent monograph has been listed, but in some 
instances earlier systematic accounts have been mentioned if they 
seemed to furnish useful information or to be more easily acces- 
sible. 

HISTORY OF BOTANICAL EXPLORATION IN MEXICO. 


Botanical history in Mexico may be considered to have begun with 
the landing of the Conquistadores, for the earliest letters of Cortés 
to the King contain references to the curious vegetable products of 
the country. The true history of botanical activity in Mexico be- 
gins at a much earlier date, for the native inhabitants, who had al- 
ready reached a high degree of civilization, may be said to have be- 
gun scientific researches. No other primitive people, probably, ever 
took so great an interest in botanical matters, and at the time of the 
Conquest none of the nations of Europe were much superior to the 
Mexicans in botanical knowledge. In one respect, at least, the lat- 
ter had made greater progress in botanical activity, for they had 
established a botanical garden, on an elaborate scale, something that 
was not attempted in Europe until a still later date. Not only had 
the Aztec people acquired an intimate knowledge of the economic 
qualities of the plants with which they came in contact, a knowledge 
possessed by all primitive peoples, but they had developed an es- 
thetic appreciation of plants for their beauty alone, a fact which indi- 
cates a rather high state of moral development. Flowers were cul- 
tivated extensively in the Valley of Mexico, and were brought in 
great quantities to the markets, where they were purchased for per- 
sonal adornment and for the decoration of residences and temples. 
This love of flowers has persisted to the present time among the Mexi- 
can people, and cut flowers still occupy much space in the markets 
everywhere in the Republic. 

Beginning with Hernandez, a large number of botanical explorers 
from Europe and from the United States have visited Mexico, and 
many native Mexicans have contributed to our knowledge of the

vegetable productions of the country. It is not the writer’s pur- 
pose to enumerate the men who have assembled the collections upon 
which the scientific knowledge of the Mexican flora is based, but 
references to most of them will be found in footnotes scattered 
through the systematic account of the flora. The earlier collectors 
have been discussed by Hemsley,? and the most complete information 
upon the subject has been published by Leén.* Several of the 
earliest enterprises for the botanical exploration of Mexico are so re- 
markable, and must be referred to so frequently in the text, that it 
seems essential to describe them in some detail. These are discussed

FRANCISCO HERNANDEZ. 


His interest in the North American colonies having been awakened, 
perhaps by the reports made by the civil and religious authorities of 
the region, Philip II of Spain gave orders to his physician, Francisco 
Hernandez, to prepare an account of the natural history, antiquities, 
and political conditions of New Spain.’ In order to give him a rank 
suitable to the importance of the work he was to undertake, Hernan- 
dez was honored with the title of Protomédico of the Indies. He 
sailed from Spain in 1570, accompanied by his son. Although Philip 
II was very liberal in his appropriations for the expenses of the ex- 
pedition, he appears to have underestimated the magnitude of the 
task, and it seems that Hernandez was often embarrassed by his lack 
of financial resources. Herndndez, however, compensated for this by 
his intense application to his work. He visited almost all parts of 
New Spain, observing all matters of natural history and collecting a 
vast amount of information. His enthusiasm led him to risk his 
health and life with experiments made upon his own person to 
determine the medicinal properties of plants discovered in the course 
of his travels. While upon a journey to Michoacin, he narrowly 
escaped death as a result of an experiment with the latex of 
“chupire.” His health was finally undermined by his excessive 
labors, the worry caused by his financial embarrassment, and the hos- 
tility shown by some of those in authority. Five years had been the 
period assigned for the cémpletion of his task, and at the end of that 
time, in 1575, he had 16 folio volumes ready for publication. Two 
years longer, however, he remained in Mexico, continually engaged

with the objects of his commission, and refusing to practice his pro- 
fession for lack of leisure from his researches, although he states that 
‘he thus lost the opportunity of gaining more than 20,000 pesos. 
Taking advantage of his title of Protomédico, he assembled many of 
the Mexican physicians and directed them to test the native drugs 
and to inform him of the results obtained. He himself carried on 
experiments in the hospitals with drug plants whose properties he 
wished to determine. 

In September, 1577, Hernandez returned to Spain. He left in 
Mexico three or four copies of his manuscripts and sketches. Be- 
sides his manuscripts and herbarium, he carried to Spain many 
seeds and living plants to adorn the royal gardens. His execution 
of his Mexican commission must have satisfied the Spanish au- 
thorities, for he was offered a similar mission to Peru and other 
parts of the Indies, which he refused because of a desire to attend 
to the printing of his reports. His expectations in this direction, 
however, were destined to be sadly disappointed, for instead of 
being sent to the printer the manuscripts were buried in the library 
of the Escorial, although, as a Mexican writer remarks, “ with every 
honor,” for they “were beautifully bound, in blue leather covered 
and worked with gold, with clasps, corners, and ornaments of silver, 
all very heavy and of excellent workmanship and design.” Not- 
withstanding this unfortunate and ironical conclusion of Hernandez’s 
expectations, Colmeiro asserts that he had seen “ a sample impression 
of the colored plates which were projected for his natural history, 
with an estimate of the cost, to judge from which the edition would 
have been of uncommon beauty, and perhaps the first of its kind for 
that time.” - 

Wearied by his disappointments, Hernandez survived only a short 
time, and died January 28, 1578. Neither the exact date of his birth 
nor his birthplace is known, nor the place where his remains rest. 
He left 16 folio volumes, six of text, describing the animals, plants, 
and minerals of Mexico, and 10 of drawings representing these ob- 
jects; also various miscellaneous manuscripts dealing with medli- 
cine, Mexican antiquities, and moral and religious philosophy. He 
had prepared a translation of Pliny’s National History, and had 
written at least two philosophical works in verse. Except for a 
few fragments, all these works were destroyed by the fire which 
consumed the Royal Monastery of the Escorial in June 1671. Of 
the manuscripts left in Mexico nothing is known, and it is probable 
that all were lost within a few years after their preparation. 

Soon after Hernaindez’s death the King moved to remedy the delay 
in the publication of his works by commissioning another of his 
physicians, Dr. Nardo Antonio Recchi, a native of Naples, to take 

126651—20——2

charge of them. The latter apparently extracted from the manu- 
scripts the portion which he believed would be most useful to the 
medical profession, for it is evident that most of the matter he | 
selected was of this sort. Some doubts have been raised regarding 
Recchi’s competency to perform the task assigned him; nevertheless 
except for his connection with the matter it is improbable that any 
portion of Hernéndez’s work would ever have been published. 
Recchi’s manuscript, however, met with no better treatment than the 
original one, for it too remained unpublished, and was taken later by 
its compiler to Naples. After Recchi’s death it came into the posses- 
sion of his nephew, from whom it was purchased by Prince Federico 
Cesi, a devoted student of natural history. By him it was turned 
over to the Accademia dei Lyncei, whose members undertook the 
arrangement and annotation of the manuscript and finally prepared 
it for publication. Through the Spanish ambassador at Rome funds 
for printing were secured, and the work of Hernandez, thus modified, 
was at last given to the public. There is considerable uncertainity 
regarding the actual date of publication, but the date of completion 
is believed to have been 1651.1. An abridged edition appeared as 
early as 1628, and extracts had been published by various authors at 
still earlier dates. -An edition of the work prepared by Ortega was 
issued at Madrid in 1780. 

Hernindez’s work is of great historic interest because of the fact 
that it is the first extensive publication dealing with the botanical . 
features of Mexico. It contains a great mass of information regard- 
ing the plants of that countrys; some of which, relating to practices 
of the early inhabitants, had been forgotten before other botanists 
visited the region. A large part of the observations relate to medic- 
inal properties of plants, and these are interesting even if not of 
much practical importance. It is unfortunate that the identity of 
many of Hernandez’s plants must remain a matter of conjecture, be- 
cause his descriptions are usually drawn in such general terms, and 
the illustrations accompanying them are often equally vague. The 
book, however, will always possess an attraction for those interested 
in herb lore if not for the taxonomist. It must be remembered that 
the work, as we have it, is not that of Hernandez himself, but only 
a compilation or an extract, and that the original manuscript if it

much greater value. 

In recent years Mr. W. E. Safford, of the U. S. Department of 
Agriculture, has spent much time in identifying the plants treated by 
Hernandez. He has published numerous papers upon the subject, 
and references to some of these will be found in the body of the 


present paper. ; 
EXPEDITION OF CHARLES III. 


The most elaborate botanical undertaking in the history of Mexico 
was undoubtedly the famous expedition of Charles III of Spain. 
That ruler decided to institute a survey of the natural resources of 
his extensive dominions beyond the sea, and for the execution of the 
project explorers were chosen from among the most learned scien- 
tists of Spain, parties of whom were sent to several of the Spanish 
possessions. One of these expeditions was dispatched to the Philip- 
pines and another, headed by Ruiz and Pavoén, to Peru. Since 
Mexico was one of the two most important of the Spanish possessions, 
the party sent to that country, New Spain, as it was then known, 
was chosen with particular care. 

It was headed by Dr. Martin Sessé y Lacasta, who was to have 
charge of a proposed botanical garden. The other members of the 
commission were D. Juan Diego del Castillo; D. José Longinos; 


D. Juan Cerda, a draftsman; and Dr. Vicente Cervantes, who 


was to establish a chair of botany in the City of Mexico. The mem- 
bers were chosen by D. Casimiro Gémez Ortega, the director of the 
botanical garden of Madrid. 

The commission arrived in Mexico in 1788, and on the Ist of 
May at 5 in the evening there was inaugurated with great solemnity 
a department of botany in the University. Sessé delivered an in- 
augural dissertation which was preceded by the installation of the 


-men chosen for the various professorships, conducted by the rector of 


the University. There were present the royal audience, the déctors, 


all of the religious societies, the regidores, military officials, and 
many members of society. The viceroy was unable to be present, 
but he was represented by D. Francisco Xavier Gamboa. 

The University was illuminated at night and after a brilliant 
concert, according to a contemporaneous newspaper account, “ there 
were lighted magnificent fireworks, ingeniously executed by that 
pyrotechnic artist, D. Joaquin Gavilan. Three trees, known in this 
kingdom under the name of papayo, closely imitating nature in the 
delineation of their leaves, flowers, and fruits, gave a clear picture 
of the sex of plants, which, being separated in this genus, was 
represented in the following manner: Two female trees, clothed 
with their respective flowers, and fruits of different stages of devel-

opment, indicated the method by which the latter take their devel- 
opment from the flowers of the male plant, which, as such, was 
without fruits and occupied the center, sending out sparks of fire, 
which, directed to the female plants, represented perfectly the pol- 
len transported through the air to fertilize the female flowers. 

“At the foot of the male tree were placed various decorations 
alluding to the features of a garden, which illuminated the Plaza 
with brilliant, spectacular, and fascinating lights of different colors 
and changed gradually into others no less entertaining. As the 
three trees disappeared there appeared an inscription in letters of 
fire which said, AMOR URIT PLANTAS, which is what the illus- 
irious Carolus Linnaeus holds in his ingenious dissertation, Spon- 
salia Plantarum.” 

At the same hour on the following day the botanical course was 
opened under the direction of Cervantes in the residence of the chief 
engineer of the city, D. Ignacio Castera, who also offered his garden 
as a laboratory. The botanical lectures were attended not only by 
the young students of the University but by numerous professional 
men, one of whom was D. José Mariano Mocifio. The city govern- 
ment lent asgistance to the new undertaking by setting apart for a 
botanical garden a parcel of land, a portion of which is now occupied 
by the home of the Instituto Médico Nacional. 

Mocifio was a young physician, native of Mexico, who so distin- 
guished himself in his botanical studies that only seven months after 
the establishment of the botanical course he was appointed member 
of the scientific commission. A fellow student, Maldonado, was 
given a like appointment, that he might engage in the work of dis- 
sections. These two, besides Castillo and Longinos, were directed to 
explore the more remote parts of New Spain, while Sessé reserved 
for himself the exploration of the central regions of Mexico, and 
Cervantes confined his attention to his professorial duties. 

Mocifio’s explorations extended on the south to the coast of Ta- 
basco, which he visited in December, 1794, continuing his course into 
Guatemala. In company with Castillo he went north to the Tara- 
humare country, into what is now Chihuahua, and later he traveled 
in California, and as far as Nootka Sound, and still later in Jalisco, 
Michoacan, and other regions. Mocifo survived the peril and fatigue 
of his travels, but not so Castillo, who died in the City of Mexico, 
July 26, 1793. 

Besides Cerda, the official artist of the expedition, D. Atanasio 
Echeverria,’ a native of Mexico, was employed in making drawings 
of botanical and other objects. A pharmacist, D. Jaime Senseve, 
also was appointed to the commission, and likewise D. José Antonio

STANDLEY—TREES AND SHRUBS OF MEXICO. 15 


Alzate y Ramirez, the latter a distinguished scientist, born in Mexico, 
who published numerous articles dealing with Mexican plants. 

Longinos engaged in the formation of collections of various objects 
and explored many parts of New Spain, his.route extending even to 
the Californias. He visited also Guatemala and Yucatan, and died 
in the port of Campeche in 1803. Some of his collections were sent 
to Madrid and part remained in Mexico. 

Mocifio was the most enthusiastic and diligent of all the members of 
the commission. He was likewise the most adventurous, and in the 
ascent of the Volcan de Tuxtla, in 1793, he came near losing his life. 
He ended his field work in 1801, and in the Hospital de San Andrés he 
conducted experiments with the medicinal plants he had collected. 
He was able to communicate to others some of his enthusiasm for 
natural history, and many people began to take an interest in the 
subject, one of the results of which was the formation of an extensive 
museum. His chief interest, however, was the task, in association 
with Sessé, of arranging and describing his botanical collections, 
with the view of publishing a work entitled Plantae Novae Hispaniae. 
He had already prepared a Flora Mexicana, and specimens from his 
collections had been sent to Lagasca and Cavanilles, who described 
some of them as new species. In addition, living plants and seeds 
were forwarded to the Botanical Garden of Madrid. 

Finally, in 1804, Sessé and Mocifio made an end of their explo- 
rations and set sail for Madrid, with a rich herbarium and a series 
of 1,400 colored drawings, as well as their precious manuscripts. 
Cervantes remained in Mexico as director of the botanical garden 
and professor of botany. 

Sessé and Mocino were filled with hope of the immediate publi- 
cation of the results of their labors, but the bitter disappointment 
experienced by Hernandez was to be the share of these two botanists 
also. They were given a cool reception and no facilities whatever for 
printing their reports. Hope of soon meeting with success in his am- 
bitions induced Mocifio to accept a meager pension from the Gov- 
ernment, and he lived as a member of Sessé’s family until the death 
of the latter in 1809. He manifested a deep interest in all scientific 
matters; he was appointed director of the cabinet of natural history 
of Madrid, gave courses in zoology, and with the assistance of another 
“Mexican, D. Pablo de La Llave, arranged the zoological collections 
of the museum. 

Mocifio seems to have been on good terms with the French, who 
invaded Spain about this time, but he became involved in difficulties 
because of his refusal to recognize one Barrois as president of the 
Academy of Medicine, of which he was a member. When the 
French Army withdrew from Madrid, Mocifio remained, presuming 
that he had not compromised himself by acting as a teacher of nat- 


16 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


ural history during the occupation, but in this he was mistaken, for 
soon after he was seized, thrown into prison, and placed in chains, 
and thus he remained until the French Army returned. Thereupon 
he was released and permitted to return to the museum. Again the 
French retreated, and Mocifio, who was now far advanced in years 
(the date of his birth is not known), resolved not to risk his fortunes 
again with the Spanish authorities, and took his departure, bearing 
with him in a cart his manuscripts and drawings. By night he 
slept in the cart, and by day he walked beside it, until it was taken 
from him by a French officer. He managed, however, to save his 
possessions and to escape from Spain, and as it was evidently un- 
safe for him to return to Madrid he took refuge at Montpellier. He 
was nearly blind and was reduced to beggary, from which he was 
rescued by certain French scientists. 

In Montpellier he became acquainted with De Candolle and Dunal, 
who joined with him in assigning names to the new species of plants 
he had discovered. To De Candolle he turned over his manuscripts 
and drawings, and that famous Swiss botanist seems to have been 
the first of those who had seen them to have formed an adequate 
idea of their value. Mocifio often visited De Candolle’s lecture 
room, and one day the latter had occasion to deliver a eulogy of 
the Mexican botanist, unaware that the subject of his praise was 
present. When the latter’s presence was pointed out to him, De 
Candolle embraced Mocifio effusively and pressed him to take the 
chair and elucidate the subject that had suggested his name. Over- 
come by the occasion, Mocifio burst into tears and was unable to 
speak a word. 

After passing a few years at Montpellier, the adoption of the 
constitution in Spain gave Mocifio hope that he might be permitted 
to return to Madrid. He besought such permission of the govern- 
ment, and it was finally granted. In April, 1817, consequently, he 
asked of De Candolle, who was now in Geneva, the return of his 
papers. The request was evidently made in urgent terms, but De 
Candolle was determined to keep copies of the drawings and descrip- 
tions, and hastened to have these made. De Candolle says that 
“About 120 persons came voluntarily to offer me their time and 
brushes; most of them were ladies of society; but there were also 
professional artists and a multitude of persons who were strangers 
to me. The young people united in the common task. The whole 
city was busy for 10 days, and the diligence of all those who knew 
how to use a brush or pencil was really affecting. * * * Asa 
result of this diligence the collection of Mocifo was almost wholly 
copied in the time fixed.” ‘De Candolle never recounted this affec- 
tionate demonstration of his fellow citizens,” says Dunal, “ but his 
eyes filled with tender tears.” The number of drawings thus copied 


STANDLEY—-TREES AND SHRUBS OF MEXICO. sa 


was 1,100, and from them 274 new species were published in the 
Prodromus. Tracings of the sketches were distributed to many of 
the herbaria of Europe. 

Mocifo returned to Spain, where he received a warm welcome 
from the Minister of Marine, D. Juan Sabat, who gave him lodging 
in his home and assisted him in other ways. Mocifio later started 
upon a voyage, but had proceeded only as far as Barcelona when 
he was overcome by illness, and he died in that city in 1819. Thus 
he failed to realize any of his hopes for the publication of the results 
of his long years of exploration and study, nor were the fruits of 
his labors destined to reach the public until still many more years 
had passed. 

His drawings passed into the possession of the physician who 
attended him in his final illness, and it is not known what finally be- 
came of them. His manuscripts and other papers, including a 
“ Flora de Guatemala,” are in the Botanical Garden of Madrid, where 
the herbarium of the expedition is said to have been deposited in 1820. 
Some of the specimens reached the Lambert Herbarium, and it is 
believed that Mexican specimens at Kew and at the British Museum, 
labeled as having been collected by Pavoén, are from the Sessé and 
Mocino collections. Presumably they were distributed by Pavon, 
and his name was affixed to the labels through some error. Pavon 
is not known to have visited Mexico. 

The Sociedad Mexicana de Historia Natural learned that the 
manuscript of the Flora Mexicana existed at Madrid, and as early 
as 1870 made an attempt to secure a copy of it, but it was 15 years 
before the attempt was successful. It was desired also to secure the 
illustrations for publication, but this was found impracticable. The 
Flora Mexicana was finally published in the City of Mexico in 1888 
by the Sociedad Mexicana de Historia Natural, and a second edition, 
with numerous corrections, was printed by the Instituto Médico 
Nacional in 1894. The Plantae Novae Hispaniae was printed by the 
former society in 1886, and was reprinted by the Secretaria de 
Fomento for the Chicago Exposition of 1893. 

It was thus more than a hundred years after the organization of 
the expedition that the results of its investigations were finally made 
public. Perhaps no other botanical project has ever had so inter- 
esting a history, and none, it may safely be said, has ever been at- 
tended with so many dramatic incidents. If they had been pub- 
lished when first written, the two floras would have become historic. 
They were better prepared than most of the botanical works of their 
day, although their authors had a very broad conception of specific 
limits and referred many of the Mexican plants to species of the Old 
World tropics with which they were not even congeneric. When the 
works were actually printed they had long been obsolete, and most

of the plants dealt with had been described years before by other 
authors, sometimes under the same names but usually not. Aside 
from the sentimental interest that was gratified by the publication 
of the manuscripts, it is a matter of regret that botanical nomen- 
clature was further taxed with so many useless synonyms. Indeed, 
but little attention has ever been paid by botanists to the numerous 
new names recorded in these two works. 


ALEXANDER VON HUMBOLDT. 


Alexander, Baron von Humboldt, one of the most illustrious men 
of his period, was born in Berlin in 1769. He was granted permis- 
sion by the court of Spain to explore the Spanish possessions in 
America, and in 1799, in company with Aimée Bonpland, he sailed 
from Coruna. He landed at Cumand, Venezuela, and starting from 
that point he explored New Andalusia (Venezuela) and Spanish 
Guiana. Thence he went to Cuba, and later to other parts of South 
America. In March, 1803, he landed at Acapulco, and followed the 
usual route of that day to the capital, where he made the acquaintance 
of Cervantes, Cal, Alzate, and many other scientists. He explored 
thoroughly the Valley of Mexico, and made collections also in 
Hidalgo, Querétaro, Guanajuato, Puebla, Jalisco, Michoacén, Gue- 
rrero, and other regions. Altogether, ten months were spent in Mex- 
ico, and in 1804 Humboldt and Bonpland returned to Paris, where 
the former remained for many years. He died in Berlin in 1850. 

The rich material obtained by the expedition was sufficient to 
occupy the many years which Humboldt devoted to scientific study. 
The botanical collections were gathered chiefly by Bonpland, but 
the senior member of the expedition made extensive observations 
upon vegetation which served as the basis for classic works upon 
phytogeography. The Mexican collections included about 950 spe- 
cies, a large proportion of which were described as new. Along with 
the material from other regions they were turned over to Kunth, who 
published seven volumes describing them.t Humboldt and Bon-

work is concerned, the Nova Genera et Species is the first important 
work treating of Mexican plants. The collections obtained in South 
America were much more extensive than those from Mexico, and for 
Venezuela, Colombia, Ecuador, and Peru the work is of even greater 
importance than for Mexico. Humboldt and Bonpland were the 
first to make known to science many of the most common and charac- 
teristic Mexican plants. 

Besides these and other systematic works, Humboldt published 
accounts of his voyages, which are replete with original observations 
upon matters of natural history. He was the father of the science 
of plant geography, and published several classic works upon the 
subject, the best known of which is his Essai sur la Géographie des 
Plantes.+ 

Bonpland was born in 1778 in the French city of Rochelle. Some 
time after his return to Europe, in 1816, he decided to establish him- 
self in America, and went to Buenos Aires, where he gave courses 
in natural history. He traveled in the more remote parts of Argen- 
tina, Paraguay, and Bolivia, and finally settled in Paraguay where 
he established a factory for the preparation of maté. This act seems 
to have aroused the jealousy of the dictator Francia, and in 1821 
a band of his agents attacked the finca, killed some of the employees, 
-and wounded Bonpland himself. The latter was put in chains 
and kept nine years in captivity, but later was released and devoted 
his attention to agricultural pursuits. He died in 1858.

Xerophilous ferns, mostly with branched creeping rhizomes; fronds usually 
ascending or reclining, numerous, somewhat vinelike, of indefinite growth, 
entangled, often forming dense impenetrable low thickets; primary axis naked; 
primary branches 1 to many pairs, opposite, determinate or (in most species) 
once to several times dichotomous, the included bud dormant or producing 
secondary and tertiary axes like the primary one; ultimate branches (pinnae) 
usually in pairs, bipinnate, pinnate, or deeply pinnatifid, the segments mostly 
elongate in our species (minute and rounded in the Old World Gleichenia) ; 
veins free, forked; sorsi dorsal or (in Gleichenia) terminal upon the veinlets, 
nonindusiate; sporangia sessile, short, 2 to many, opening by a vertical fissure.

Widely distributed in tropical and subtropical regions of both hemispheres. 
In tropical America many of the species grow rankly in the greatest profusion, 
often occupying wide areas of open or thinly shaded mountain slopes to the 
exclusion of other vegetation. A mass of the wiry interlacing fronds, with a 
blanket thrown over it, makes an excellent bed for the collector.

189. 1899; Maxon, The tree ferns of North America, Ann. Rep. Smiths. Inst. 
1911: 4638-491. pl. 1-15. 1912. 

Mainly treelike plants of moist tropical regions, the rhizome stout and 
woody, decumbent, oblique, or usually erect, and 1 to 15 meters high or more, 
naked, with smoothish, usually tesselate leaf scars, or rough and partially 
sheathed by the imperfectly deciduous stipe bases of the fronds of previous 
years; fronds borne in a terminal scaly crown, several or many, ascending to 
recurved, the blades 1 to 4-pinnate, up to 4 meters long, usually broad; sori 
indusiate or nonindusiate, nearly globose, borne dorsally upon the veins on the 
under surface of the blade or at the margin, the receptacle elongate, of various 
form and vestiture; sporangia numerous, crowed radially in several ranks, 
opening horizontally, the annulus oblique, with or without a stomium of thin- 
walled ceHs; spores triplanate. ” 

The Cyatheaceae, or tree-fern family—the latter name given because, in 
contradistinction to all other families of ferns, the species are nearly all 
arborescent in habit of growth—are practically confined to tropical and sub- 
tropical regions and attain their best development, both as to luxuriant growth 
and as to number of species and individuals, in mountainous regions which 
have a nearly uniform, moist climate. Except in a very few cases they ap- 
parently can not endure extremes of either drought or cold. Thus in Mexico, 
as in Central America, they are practically confined to the Atlantic slopes and 
to the higher mountain regions that are constantly swept by the moisture- 
laden trade winds from the Gulf of Mexico. This territory embraces Vera- 
eruz and Tabasco and most of Oaxaca and Chiapas. From the arid interior 
plateau regions they are altogether lacking. Comparatively little material hav- 
ing been collected in extreme southeastern Mexico in recent years, our knowl-

edge, both of the species actually occurring there and of their geographic 
distribution, is very incomplete. Tree ferns are, as a rule, of restricted 
range, yet many of the Mexican species are known from Alta Verapaz, Guate- 
mala, and of the remainder most, at least, may be expected to occur there. 
With a very few exceptions, the Mexican species are exclusively continental, 
and only a few extend as far south as Panama. 

Aside from the attention attracted by their beauty and stately habit of 
growth, tree ferns are decidedly interesting because of their marked diversity 
in structural characters and, unfortunately, their difficult classification. Lo- 
cally, at least, they serve varied economic uses also, the most important being 
the use of the trunks as building timbers. These are composed largely of a 
branched network of hard fibrovascular elements, resistant to decay and the 
attacks of termites alike, permitting the use of the trunks over and over again 
in the supporting framework of native houses. Occasionally they are made to 
serve as telegraph poles. Small pieces of the fibrovascular elements are em- 
ployed in inlay work. In Costa Rica the succulent unrolling young fronds or 
“erosiers’’ of a Cyathea called ‘rabo de mico” are eaten as a salad. The 
scales of a related species (probably Cyathea mexicana), known in Veracruz 
as “ocopetate” or ‘‘cola de mono,” are applied topically as a hemostatic. A 
like use of the matted capillary’ scales or “pulu” of Hawaiian species of 
Cibotiwm is, of course, well known. Several species of Hemitelia and Alsophila 
are known as.“ tatahueso ”’ in Oaxaca, according to Reko.

The pines are perhaps the most important genus of North American trees. 
They are certainly the most important group of lumber trees, the wood, varying 


STANDLEY—TREES AND SHRUBS OF MEXIGO. ois 


in quality in different species, being used for almost every purpose for which 
wood is commonly employed. In the mountains of Mexico large quantities of 
pine lumber are sawed and much is exported. 

The resinous juice is of great economic importance, being the source of 
turpentine, resin, tar, and other products. When the juice, which is obtained 
by tapping the trees, is distilled, oil or spirits of turpentine is produced. This 
has many well-known uses in the arts and in medicine. The residue left from 
the distillation is the resin of commerce. By crude distillation of the wood, 
pine tar is obtained, with a residue of charcoal. Tar subjected to distillation 
yields oil of tar and a thick residue known as naval pitch. 

Pine wood is used extensively in Mexico for fuel. Bundles of splinters of 
pitch pine to be used in starting fires are seen commonly in the markets. Some 
of the North American Indians in times of famine have used the sapwood and 
inner bark for food, and they have also employed strips of the inner bark for 
making baskets. Some tribes still use resin to waterproof baskets and jars 
of wickerwork. 

Pine leaves are sometimes mixed in adobe bricks in place of straw. The 
leaves are very tough, and the longer ones occasionally serve as a substitute 
for twine. The branches are employed in some localities for thatching. A 
volatile oil obtained from the leaves is used in medicine, and pine tar also is 
employed medicinally. The cones are used in place of combs by some of the 
Indian tribes. 

The pines are often planted for ornamental purposes, and some of the 
Mexican species have been cultivated in Europe, although few of them thrive 
there. Pinus halepensis Mill. and P. pinea L., European species, are said to be 
cultivated in Mexican parks. 

In Mexico pines are most generally known under the names “ pino”’ (Spanish) 
and ‘“ ocote,” the latter a corruption of the Nahuatl “ ocotl.” Besides the ver- 
nacular names listed under the various species, the following names are applied 
to Mexican pines, although it is uncertain to which species they belong: “ Pino 
barbén” (Durango); “ pino triste” (Durango) ; “ pino de azfiicar” (Durango; 
“perhaps P. ayacahuite”’) ; “ pino prieto”’ (Durango, Sinaloa) ; “ guiri-biche” 
(Oaxaca, Zapotec, Reko). 

In 1857 there was published in the City of Mexico a “ Catalogue de Graines 
de Coniféres Méxicains ” by B. Roezl & Cia. In this 82 new species of Mexican 
pines were described, nearly all from the Valley of Mexico. The most compe- 
tent students of the genus have concluded that all these new names are prop- 
erly referable to earlier published species. It does not seem necessary to list 
the numerous names in synonymy here, but those who wish to refer to them 
will find them tabulated in Shaw’s monograph referred to above.

Pinus cembroides monophylla Voss, Mitt. Deutsch. Dendr. Ges. 16: 95. 1907. 
Mountains of Northern Baja California. Southern California (type locality) 

to Utah. 

Tree, usually 7 meters high or less, but sometimes attaining a height of 15 
meters and a trunk diameter of 30 cm.; trunk short, often branched near the 
base, the bark deeply and irregularly fissured, dark reddish brown; leaves 
about 4 cm. long, pale green; cones 4 to 6.5 cm. long, light reddish brown, 
shining, the scales few, thick; seeds about 1.5 cm. long; wood soft, brittle, 
weak, close-grained, yellow to light brown, its specific gravity about 0.56. 
“Pindn” (California, Arizona). 

The wood is used for fuel and for charcoal for smelters. The seeds are 
edible, either raw or roasted, and they are sometimes ground into meal. 


2. Pinus edulis Engelm. in Wisliz. Mem, North. Mex. 88. 1848. 

Pinus cembroides edulis Voss, Mitt. Deutsch. Dendr. Ges. 16: 95. 1907. 

Dry mountain sides, Baja California, at an altitude of about 1,800 meters; 
perhaps also in northern Chihuahua. Western Texas to Arizona and Wyoming; 
type from New Mexico. 

Sometimes reaching a height of 12 meters and a trunk diameter of 75 cm., 
but usually smaller; trunk short, often divided to the base, the bark brown, 
irregular fissured; leaves 1.8 to 4 cm. long, green; cones about 4 em, long, the 
few scales very thick; seeds brown, about 1.2 cm, long; wood soft, weak, brittle, 
close-grained, pale brown, the specific gravity about 0.64. ‘“ Pifén” (New 
Mexico, Arizona, etc.). 

In the United States the wood is used for fencing, fuel, and charcoal, and is 
sometimes sawed into boards, although it is only rarely suitable for lumber. 
Pinyon seeds are an important article of food in New Mexico and Arizona, 
-largely taking the place filled by peanuts in other parts of the United States. 
They were a staple food, also, of the Indians, In New Mexico they are some- 
times gathered in such large quantities as to be used for horse feed. The nuts 
are sometimes exported to other regions, and have been used in making confec- 
tionery.

2.5 to 5 em. long, dark green; cones 3 to 5 cm. in diameter, reddish brown; seeds 
8 to 10 mm. long; wood soft, close-grained, yellow, its specific gravity about 
0.65. Known generally as ‘ pindn” or “pino pion,” the seeds as ‘ pifiones.”’ 

The seeds are eaten in all regions where the nut pine grows, and are highly 
esteemed. They are very palatable raw, but are improved by roasting, after 
which they possess a flavor unexcelled, perhaps, by that of any kind of nut. 
The seeds are placed in the mouth and the thin shells are cracked with the 
teeth and ejected without being touched by the fingers, an operation in which 
one may become very .proficient by a little practice. The nuts are often 
added to candies.

1Thomas Coulter (1793-1843) came to Mexico in 1825 as physician for a 
mining company in Hidalgo. He remained there for a number of years and 
made collections of plants. From 1831 to 1833 he explored Alta California 
(now chiefly included in the State of California) and later Sonora, being the 
first collector who forwarded to Europe collections from the latter region. 
His collections were sent to Trinity College, Dublin, from which institution 
they were distributed to various herbaria. A few of his plants are in the 
U. S. National Herbarium. 5

? Little is known concerning Josiah Gregg, who was a trader under the 
patronage of Thomas G. Rockhill, a Philadelphia merchant. He published in 
1844 “The Commerce of the Prairies,’ in which he tells of his travels in the 
West, and of his residence of nearly nine years in northern Mexico. He made 
botanical collections in Mexico, and his specimens are chiefly in the herbarium 
of the Missouri Botanical Garden. He is believed to have died in California 
in 1850. The genus Greggia, of the family Brassicaceae, was named in his 
honor by -Gray.

Tree, in Oregon and Washington sometimes reaching a height of 90 meters, 
with a trunk diameter of 4.5 meters, but usually smaller; bark thick, deeply 
fissured; cones purplish at first, yellowish brown when mature; wood hard, 
light red and coarse-grained or yellowish brown and fine-grained, the specific

This tree (known in the United States as Douglas fir) is of the greatest 
commercial importance in the United States, especially on the Pacific coast, as 
well as in those portions of Mexico where it is abundant. It furnishes the 
largest saw timber of any of the North American trees, if not of any trees in 
the world. The wood is used for all kinds of construction purposes, especially 
those which require large timbers, such as shipbuilding. It is used also for 
railroad ties. Large quantities of the lumber are exported from the United 
States. The bark is sometimes employed for tanning leather. The smaller 
roots are very uniform in diameter for a length of 2 to 3 meters and have been 
a favorite material of the California Indians for the manufacture of baskets. 
It is said that in the same State a decoction of the green leaves has been used 
by both Indians and white people as a beverage in place of coffee; and a decoc- 
tion of the spring buds has been employed as a remedy for venereal diseases.

for the oleoresin which they yield abundantly. This, known as “aceite de 
palo” or “aceite de abeto,” is used in medicine for its balsamic properties, 
and as an ingredient of paints. The specific name “ religiosa” was applied 
to the tree because of the fact that its branches are often used as decorations 
in churches.

shade tree. Guatemala. 

Large tree, 20 to 30 meters high; trunk straight, enlarged near the base, 
covered with brownish red, rather smooth but shredded bark; roots of trees 
growing in water often sending up conical projections or ‘‘ knees;” leaves 
(and many of the young branches) deciduous, 6 to 12 mm. long; staminate 
flowers in long slender spikes; cones subglobose, 1.5 to 2.5 em. in diameter. 
The Nahuatl name is ‘“ ahuehuetl,’ in modern Mexican “ ahuehuete’”; the 
Tarascan name is “pentamu” or “pentam6én;” “ciprés” (Tamaulipas) ; 


“cipreso” (Chiapas); “sabino” (Durango, San Luis Potosi, Oaxaca, and

or ‘“ yaga-guichi xifa” (Oaxaca, Zapotec, Reko). 

This bald cypress is one of the best-known trees of Mexico, being noted 
especially for its size. The largest individual reported is the famous tree at 
Santa Maria del Tule, Oaxaca, near the city of Oaxaca, which has a height 
of 38.6 meters and a trunk circumference of 51.8 meters;* the greatest diameter 
of its trunk is 12 meters, and the spread of its branches about 42 meters. 
The Cypress of Montezuma, in the gardens of Chapultepec, has a height of 
51 meters and a trunk circumference of 15 meters. It was a noted tree four 
centuries ago, and has been estimated to be about 700 years old. Other trees 
have been estimated to have attained a much greater age. A third famous 
tree is the “Arbol de la Noche Triste,” in the village of Popatela, near the 
City of Mexico, which is noted for its association with Cortés. 

The wood is soft and rather weak, light or dark brown or yellowish, and 
is often obtained in very large planks. It is susceptible of a good polish and 
is used in Mexico for fine furniture, as well as for general construction. The 
tree furnishes an acrid resin which was used in pre-Conquest times for the 
cure of wounds, ulcers, cutaneous diseases, toothache, gout, ete., and which is 
still used extensively in popular practice. The bark is employed as an emmena-

gogue and diuretic, and the leaves are applied as a resolutive and as a cure 
for itch. Chips of the wood are placed in an excavation in the ground, covered 
with earth, and fired, and as a result there is obtained a kind of pitch which 
is used commonly as a cure for bronchitis and other chest affections.2 


5. JUNIPERUS L. Sp. Pl. 1088. 1753. 


Trees or shrubs with small scalelike leaves, these opposite or verticillate ; 
fruit a small globose cone, often berry-like. 

Cedar wood is of much economic importance, being useful for many purposes, 
one of the most common of which is the manufacture of lead pencils. The 
bark is rich in tannin and is used for tanning leather. The volatile oil 
obtained from the fruit of some species is aromatic, stimulant, and diuretic, 
Spirits distilled with the berries of common juniper (J. communis L., of North 
America, Europe, and Asia) constitutes the gin of commerce. The leaves, or 
their decoction, of J. sabina L. (of Europe) and J. virginiana L. (of the United 
States) have been used as a teniafuge and abortifacient, although their use is 
dangerous. The trees are very commonly planted for ornamental purposes.

In their general appearance these leafless plants are very unlike any others 
found in North America. The stems have an astringent taste and contain 
tannin, but they are much eaten by stock. A decoction of the stems is used

Herbs or rarely shrubs or trees; leaves usually long and narrow, but in the 
woody species usually lanceolate or elliptic, often petiolate; -flowers small, 
greenish, or purplish, arranged in small spikelets, the spikelets in narrow or 
open panicles; fruit a caryopsis or grain. 

Most of the woody grasses belong to the tribe Bamboseae, usually known in 
English-speaking countries as bamboos. In tropical America there are few 
.grasses, aside from bamboos, that have woody stems, and nearly all of these 
belong to the genus Lasiacis of the tribe Paniceae. 

It is impracticable to draw a sharp distinction between woody and herba- 
ceous grasses. In the following account only those species have been included 
which possess culms that persist from year to year. Some excluded species 
have woody crowns or have the base of the culms woody; others, such as the 
sugar cane and reed (Phragmites communis Trin.), have large firm culms that 
appear woody during the season of growth, but do not persist.

REFERENCE: Oersted, Nat. For. Kj6benhavn Vid. Medd. 1858: 1-54. 1859- 

The palms are one of the most interesting and important groups of Mexican 
plants. Although the number of species represented is not nearly as large as in 
Central America, or farther southward in South America, those which are 
found in Mexico are of great economic importance. The plants attract 
attention because of their curious and beautiful forms, and they are favorite 
ornamental plants in Mexican parks and gardens. Besides the native species, 
some exotic ones are cultivated. The species are widely distributed in Mexico 
and often form extensive forests. 

The trunks are used for making the walls and roofs of houses, and the leaves 
are the usual material employed for thatch. The juice of the stems usually 
contains sugar, and may be fermented to obtain intoxicating drinks. The 
tough leaves are made into hats, mats, raincoats, and other articles, and their 
fiber furnishes cordage. The fruits of many of the species are edible, and the 
seeds contain large quantities of oil. 

The writer is under special obligations to Mr. O. F. Cook for assistance in the 
preparation of the account of this family.

* This species is one of the commonest palms cultivated in hothouses. It is 
grown in parks in Sonora, where it is known as “palma de Castilla.” The 
desert Indians of southern California utilized the leaves for building huts and 
strands from the leaves for tying and in basketry. The fruit was eaten fresh 
or dried, the seeds were ground into meal, and the terminal bud or “ cabbage” 
was roasted and eaten.

Brahea armata S. Wats. Proc. Amer. Acad, 11: 146. 1876. 

Glaucothea armata Cook, Journ. Washington Acad. Sci, 5: 237. 1915. 

Along canyons and arroyos, northern Baja California; type from Tantillas 
Mountains. 

Trunk sometimes 12 meters high and a meter in diameter, but usually about 
6 meters high; leaves very numerous, the blades glaucous, the petioles armed 
with curved teeth; inflorescence slender, exceeding the leaves, the flowers dull 
purplish. “Palma blanca” (Sonora). 

This species is cultivated in southern California and in Sonora. It has been 
made the type of a new genus, Glaucothea, by Cook. While this genus is appar- 
ently well founded, it seems impracticable to recognize it in the present work, 
since the position of some of the other species, especially E. elegans, is doubtful. 


3. Erythea brandegeei* Purpus, Gartenflora 1903: 12. f. 1, 2. 1903. 

Mountains of the Cape Region of Baja California. 

Trunk 30 meters high or higher, about 60 cm. in diameter or less, smooth ; 
leaves 10 to 12, the blades subtomentose, sparsely filiferous, green above, pale 
beneath, about 1 meter long; petioles glabrous, 1 to 1.5 meters long, spine- 
toothed ; inflorescence tomentose; fruit 10 to 15 mm, in diameter. “ Palmilla,” 
“palma negra,” “palma de Tlaco.” 

The tender buds are eaten. 

4, Erythea aculeata T. S. Brandeg. Zoe 5: 196. 1905. 

Sinaloa; type from Cofradia. 

Trunk 6 to 7 meters high; leaf blades 40 to 60 cm. long, with about 40 
segments, slightly filiferous; petioles slender, 50 cm, long or longer, the mar- 
gins armed with short teeth; fruit globose, 2.5 cm. in diameter. 


21Named for T. S. Brandegee (1843-) who has made large collections of 
Mexican plants, chiefly in Baja California, but also in Sinaloa. He has pub- 
lished several papers upon the plants of Baja California, which are our most 
important sources of information upon the botanical features of that region. 
He has published, also, papers dealing with plants from other parts of Mexico, 
especially the recent collections obtained by C. A. Purpus. The Brandegee 
Herbarium is at the University of California, but large numbers of the plants of 
Mr. Brandegee’s collections are in the U. S. National Herbarium.

1. Phoenix dactylifera L. Sp. Pl. 1188. 1753. 

Widely cultivated in Mexico and in some places, as in Baja California, grow- 
ing without cultivation, perhaps on the sites of abandoned ranches. Native of 
the Old World. 

Trunk often 15 meters high or taller; leaves large, pinnate; fruit borne in 
large panicles. Commonly known as ‘datil;” the name “ zoyacapulin” is 
said to be applied also. 

One of the best-known palms, grown for its fruit in most tropical regions. 
The date palm was introduced into Mexico at an early period and is now 
cultivated in many localities, chiefly in the more arid regions. Dates were 
exported from Baja California in the early part of the nineteenth century, but 
the amount now produced in Mexico is not very large. They could doubtless 
be grown on a large scale in Sonora and Sinaloa, for the trees thrive in that 
part of Mexico.

? August Ghiesbreght was born in Brussels in 1810. In 1836 he and Linden 
were appointed by Leopold I to explore Brazil. In 1837, together with Linden 
and Funck, he started for Mexico and reached Veracruz in January, 1838. 
He accompanied Galeotti in his ascent of Orizaba, and also collected else- 
where. He went to Europe in 18389, but returned to Mexico in the same year, 
and with Linden visited Tabasco. In March, 1840, he accompanied his collee- 
tions to Europe, but returned soon after, and botanized in various states, as- 
cending the volcanoes of Colima, Jorullo, and Zempoaltepec. He took up his 
residence in Tabasco, and explored that State as well as Chiapas. In 1857 he 
again accompanied his collections to Europe, to return once more, however, 
and establish himself in the city of Chiapas. His collections are found in 
many of the herbaria of Europe and America.

Carl Sartorius, a native of Darmstadt, Germany, was obliged by political 
conditions to leave his native country in 1826, and in 1830 he took refuge in 
Mexico. He purchased land at Mirador, at the base of Mount Orizaba, and en- 
gaged in agricultural pursuits. He made large collections of plants which are 
deposited in various herbaria of Europe and the United States. His death 
occurred in 1872.

1¥Wrederick Michael Liebmann (1813-1856), a Dane, was sent by the Danish 
Government to Mexico in 1840, in company with a gardener, Rathsack, to make 
scientific collections, especially of living plants and seeds for the botanical 
garden of Copenhagen. He landed at Veracruz in February, and with Kar- 
winsky he explored that State, making his headquarters at Mirador. Later 
he visited Puebla and Oaxaca, and in 1843 he returned to Copenhagen witt: his 
collections, which consisted of 40,000 botanical specimens. He was appointed 
professior of botany at Copenhagen in 1845 and director of the botanical gar- 
den in 1849. He published numerous papers based upon his collections, and 
after his death Oersted also published descriptions of some of the new species 
discovered. His plants were distributed to many of the herbaria of Europe 
and the United States.

* Christian Julius Wilhelm Schiede (1798-1836), a German, studied natural 
science, especially botany, at Berlin and G6éttingen, and, as a means of assist- 
ance in his proposed botanical explorations, medicine. Accompanied by an- 
other botanist, Deppe, he reached Mexico in 1828. The two spent about a year 
in exploring the State of Veracruz, and obtained large collections of plants 
and other objects. Schiede then took up the practice of medicine, which gave 
him means to explore other regions of Mexico. His collections were studied 
chiefly by Schlechtendal and Chamisso, who published numerous papers deal- 
ing with them in Linnaea. Schiede himself published descriptions of some of 
the new plants he discovered,,. as well as letters dealing with the general 
aspects of Mexican vegetation. He died in the City of Mexico in 1836. His 
plants were widely distributed, the most complete series being at Berlin; a 
few are in the U. S. National Herbarium.

1. Cocos nucifera L. Sp. Pl. 1188. 1753. 

Common along both coasts of Mexico, often cultivated. Widely distributed 
in tropical regions. 

Trunk slender, sometimes 30 meters high with a diameter of 60 to 70 em., 
usually enlarged at the base, normally erect but often bent over by wind; leaves 
pinnate, 3 to 6 meters long; flowers white, borne in large panicles. Known 
commonly in Mexico as ‘“ coco,” ‘ cocotero,” “palma de coco,” and “ coco de 
agua;” also as “coco de castillo.” 

The best known and most important of all palms, of frequent occurrence 
along the coasts of Mexico, growing normally in the immediate vicinity of salt 
water. The trunks are used for building dwellings and for rafts and the leaves 
for thatching. The meat of the nut is a favorite article of food and large 
amounts are used for making “ dulces” or sweetmeats. The milk of the fresh 
fruits is a refreshing drink and is said to have diuretic properties. The fruit 
has the reputation, in Cuba and Yucataén, of expelling intestinal parasites. 

On the west coast of Mexico, particularly in Colima, an intoxicating drink 
ealled “tuba” is made from the sap obtained from the trunk or from the 
inflorescences. This is sometimes flavored with pineapple, lemon, onion, 
chile, or cinnamon, when it is known as “ tuba compostura.” The “tuba” is 
distilled to obtain alcohol, and also furnishes vinegar. 

The shells of the nuts are made-into cups and other articles. Oil is ex- 
pressed from the meat, and small quantities of it have been exported from 
Mexico, 

In other regions of the world the different parts of the coco palm are em- 
ployed for an infinite variety of purposes which it seems unnecessary to eun- 


merate here.*

1. Attalea cohune Mart. Hist. Nat. Palm. 3: 300. pl. 167. 1836-50. 

Jalisco to Oaxaca and Yucatén, chiefly in the littoral regions. Central 
America; type from Honduras. 

Trunk often 50 to 60 meters high, when short usually covered with per- 
sistent leaf bases; leaves very large, sometimes 7.5 meters long (said to be 
even 18 meters long and 2.5 meters wide), gracefully recurved, pinnate, with 
yery numerous segments; inflorescence 1.5 to 2 meters long; fruit resembling 
a small coconut, about 7 cm. long, mamillate at the apex, subtended by the 


accrescent perianth; seeds large, very oily. ‘‘Corozo” (Yucatan, Oaxaca, 
Guatemala, Costa Rica); “palma de coquito de aceite,’ “coquino,’? “ coco 
de aceite,’ “coquito” (Colima); “palma real,’ “corozo gallinazo” (Pan- 
ama); ‘“cohune” (Honduras, Guatemala); “monaco,” “manaca” (QGuate- 


mala) ; “coco de Guadalajara” (Chihuahua, in market). 

The tallest and most showy of Mexican palms and one of the most im- 
portant ones economically. The trunks are used for building purposes and the 
leaves for thatching. From the trunk a liquor similar to that of the coco palm 
is obtained. The flowers have a heavy, unpleasant odor, and attract bees and 
wasps. The young bud or “ cabbage” is cooked and eaten, and in Costa Rica, 
at least, the young leaves are used for making hats. The fruits, however, are 
the most important part of the plant. They are much eaten by cattle, and the 
seeds are used for human food, especially for the preparation of sweetmeats. 
The seeds contain about 50 per cent of oil, which is extracted by pressure, and 
is used chiefly for making soap, but also for candles, machine oil, etc. One 
soap factory at Guaymas is said to have used 100,000 pounds of the oil a 
year. 

Two species of Cocos described from Mexico by Liebmann probably belong to 
this genus. They may be synonyms of Attalea cohune, or they may represent 
distinct species, for there is reason to believe that more than one species of 
Attalea occurs in Mexico. Cocos regia Liebm. (Mart. Hist. Nat. Palm. 3: 323. 
1836-50) was based upon material from the mountains of eastern Mexico. C. 
guacuyule Liebm. (Mart. loc. cit.) was collected near Guatulco, at an altitude 
of 360 meters. The latter name has been much used in Mexican literature for 
the plant here listed as Attalea cohune. The following vernacular names have 
been reported: “ Coyol,” “ coyole,” “ guacoyul,” “ huiscoyul,” “ quacoyul.”

The fruit is edible and is often found in the markets. It is said that an in- 
toxicating liquor is made from it.

_ The leaves are said to give a fine, strong fiber. The flowers were eaten 
formerly by the California Indians, and Palmer states that the seeds, also, 
were ground and eaten, either raw or in the form of porridge.

The large trunks are used for fences.or for the walls of houses, and some- 
times they are split open so that the soft interior may be eaten by stock. The 
large flower panicles are eaten greedily by cattle and are sometimes gathered 
for this purpose. The immature inflorescences are used also for human food, 
boiled or roasted. The leaves yield a fiber (known in Zacatecas as “ palma 
ixtle” fiber) useful for cordage. The pulpy, sweet but somewhat bitter fruits 
are eaten by people as well as by wild and domestic animals.

The plants of this genus are distributed nearly throughout Mexico, but are 
most abundant in the more arid regions east of the western Sierra Madre, 
where they are often the dominant feature of the landscape. Yuccas are of im- 
portance from an economic standpoint, although much less so than the genus 
Agave. 

The most important product is the fiber obtained from the leaves, which, 
however, is usually coarse and shorter than is desirable in commercial fiber. 
It is extracted usually in a crude fashion, and is an article of export. It may 
be that in time its extraction will be of considerable importance commercially. 
During the war-shortage of raw materials this fiber has acquired considerable 
value in the southwestern United States, especially that of Yucca elata. The 
fiber is much used locally for cordage, and it has been woven into mats and 
cloth by the Indians of Mexico and the United States. It is said that the cloth 
(“ayate”) bearing the famous likeness of Our Lady of Guadalupe is made 
of Yucca fiber, but this may be incorrect. 

The trunks of the arborescent species are often used for stockades and_ for 
walls of houses, and the leaves are used for thatching. Paper can be made from 
the fiber of the trunks and leaves. 

The plants possess the saponifying properties of the genus Agave. The roots 
(under the name “amole’”’) are used widely for washing clothing, the hair, 
ete., and they have been used in the United States in the manufacture of fine 


90 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


toilet soap. An extract of the roots has been employed to produce foam in 
beverages. 

The plants are of some importance as forage, chiefly in times of severe 
drought, when cattle often eat the stiff leaves. The flower panicles are much 
eaten by cattle. The flowers, either in bud or just after they have opened, have 
long been an article of human food in Mexico and they are frequently found in 
the markets at the present time. They are eaten raw as a salad, or are cooked 
in various ways, and are sometimes made into a conserve. They are slightly 
bitter and are reputed to have tonic properties. 

The fruits of those species with baccate fruit, usually known as “ datiles,” 
are eaten by birds and mammals and by man. They contain much sugar but are 
more or less bitter. They are eaten either raw or cooked, and some of the 
Indians, of the United States at least, dried them for use in winter. The fruits 
are also fermented and sometimes distilled to produce an alcoholic beverage. 

Various statements are made concerning the seeds. Palmer reports that the 
Indians used them for food. Others state that they are purgative, while Cer- 
vantes says that they are useful for the treatment of dysentery. 

Many of the species of Yucca are used as ornamental plants, especially in 
arid regions. They are admirably suited for this purpose because of their 
showy flowers and striking palmlike appearance.

*Arthur Carl Victor Schott (1814-1875), a native of Germany, came to the 
United States in 1850. He was appointed a member of the scientific corps of 
the commission to establish the boundary between the United States and 
Mexico, and in the course of his work made large botanical collections. In~™ 
1864 he was commissioned by the governor of Yucatin to make a geological 
survey of that State, and here, also, he secured botanical collections. The 
most complete representation of his Yucatén plants is in the herbarium of the 
Field Museum of Natural History, but many of his specimens are in the U. S.

The hollowed trunks are used sometimes for beehives. The leaves give a 
fiber useful for cordage, and the fiber is sometimes dipped in pitch to make 
torches for use in mines. The young stems and leaves have been distilled to 
obtain alcohol. The spongy interior of the trunk is cut into long strips, beaten 
flat, washed in running water, and made into mats which are used as pads

Acaulescent or arborescent plants; leaves linear, usually with very spiny mar- 
gins, the bases much broadened; flowers small, whitish, paniculate. 

The plants grow mostly on dry, rocky mesas or hillsides and are often very 
abundant and conspicuous. The trunks are used frequently for building houses 
and for fuel. When one of the plants, covered with the dead leaves, is set on 
fire it will burn for some time, and the burned stumps are a familiar sight in 
regions where the plants occur. The leaf bases remaining on such burned 
plants, when removed from the trunk, make very satisfactory beds upon camp- 
ing expeditions, for they are elastic and not uncomfortably hard. The trunks 
are often split open to permit cattle to eat the spongy interior, for this, as well 
as the leaf bases, contains much sugar and has been found td be an excellent

food for cattle, especially in time of drought. In New Mexico and western 
Texas the plants have been used on a large seale for this purpose, often 
after having been transported by railroad. The plants were formerly much used 
for food by the natives of the arid regions, and are still so used to some extent. 
The leaves are trimmed off and the remaining head is roasted or boiled and 
the sweet pith and leaf bases then eaten. The heads are often baked for about 
24 hours in pits dug in the ground. The roasted trunks are also allowed to 
ferment and then distilled to obtain’ a highly esteemed intoxicating drink known 
as “sotol,” which is a colorless liquor of penetrating odor and peculiar taste. 
Alcohol has been extracted from sotol plants upon a commercial scale. 

The leaves are much used for thatching, baskets, rough hats, mats, ete., and 
their fiber for rough cordage. The fiber seems to be suitable for the manufac- 
ture of paper. ;

The species of Smilax which furnish the sarsaparilla of commerce are very 
imperfectly known, but this species is‘believed to be one of the chief sources of 
the drug. The Nueva Farmacopea Mexicana states that this is the only species 
of Eastern Mexico whose rhizomes are employed medicinally. and Smilar 
medica is one of the official sources of sarsaparilla according to the U. S. Phar- 
macopoea. Not much dependence can be placed upon either of these state- 
ments, however, because the species are poorly known, and the rhizomes 
have not been associated with botanical specimens of the plants which produce 
them. 

The rhizomes are dug at any time of the year and dried in the sun. Théy 
contain a erystalline principle, parillin, upon which their virtues depend. This 
has sudorific and stimulant properties. Sarsaparilla was introduced into Spain 
about 1540, and was widely used as a remedy for veneréal diseases. It is still 
employed for the same purpose, and for rheumatism, scrofulous diseases, and 
some cutaneous affections. It is widely employed also for flavoring beverages. 
Large amounts of sarsaparilla have been and still are exported from Mexico. 
It is said that the rhizome, of a fern, known as “zarzaparilla de Tierra 
Caliente,” is sometimes used as an adulterant.

The leaves contain an excellent fiber. That of A. americana, which is much 
planted and has escaped around the Mediterranean, is used in the dainty pita 
lacework of the Azores, etc. Much of the fiber of the lechuguwilla type of plants 
is used for coarse sacking or enters into the complex of ixtle or Tampico fiber 
or Matamoros fiber. Agave cantala is grown extensively in tropical Asia for 
its fiber. Of recent years the zapupes have been exploited as equally worthy 
with the henequen or Sisal hemp, which forms the chief basis of Yucatecan 
commerce and is being extensively planted through tropical regions. The 
national drink of the Mexican Indians is fermented from the exuded sap of 
the large fleshy-leaved or maguey species when they are ready to bloom, and 
great plantations are maintained for this purpose on the table-land; and a 
great deal of distilled liquor, called mezcal, like the smaller-leaved species used 
for the purpose, is distilled from a fermented mash made from the roasted 
stems of many species, especially those of the group Tequilanae, which are 
grown in large numbers for this purpose, particularly about Tequila in the 
State of Jalisco. The glucoside saponin occurs in many species and is very 
abundant in the rootstocks of a few agaves and particularly in those of the 
related herbaceous genus Manfreda, and these are used for washing under the 
name ‘‘amole.” The fiber of the leaves was used in preconquest days for mak- 
ing a kind of paper, upon which manuscripts were written. 

The species of Agave are known in the United States as century plants. This 
name was given because of a belief that the plants flowered only when they had 
attained an age of a hundred years. This belief is, of course, incorrect. It is 
probably due to the fact that in cultivation the plants rarely bloom. In Europe 
the plants are often known as American aloes, because of a slight resemblance 
to Old World plants of the genus Aloe, of the family Liliaceae.

*Named for Capt. John Donnell Smith (1829-), of Baltimore, Maryland, 
well known for his extensive publications upon the botany of Central America. 
Capt. Smith has made collections in Central America, and has directed botanical 
explorations in many parts of that region. His large herbarium, which con- 
tains a wide representation of Mexican plants, and his library, have been pre- 
sented to the Smithsonian Institution, and are incorporated in the U. S. 
National Herbarium.

A close ally of the “ zapupe” and especially the ‘“‘ Tequila mezcal’”’ species; 
cultivated for its fiber in the Philippines as “ maguey ” or “‘ Manila aloe,” and 
in India where it is the source of ‘‘ Bombay hemp” or ‘‘ Bombay aloe fiber.” 

Apparently one of the west-Mexican allies of A. tequilana, perhaps early 
taken for its fiber to the Philippines and thence to India, from the Acapulco 
region.

A. cervus, A. cholulensis, A. cinerea, A. citrulacea, A. crispa, A. echidne, A. 
elegans, A. flava, A. foliosa, A. funis, A. glauca, A. insulsa, A. lutea, A. lutea

spinaceum, A. spinosa, A. spinosissima, A. superba, A. torosa, A, variegata, A. 
vesca, A. violacea, and A. viridis. Aztec names, based on the word metl and 
not maguey, are given frequently to the forms recognized by planters. 

Quite as disconcerting as to differentiate these, is any effort to recognize a 
number of the nominal species of this group based on young plants cultivated 
in European gardens a generation ago. A gray-leafed form closely allied to 
the green atrovirens but with leaves less narrowed at base is var. salmiana 
(A. salmiana Otto in Salm-Dyck, Bonplandia 7: 88. 1859), the scape of which 
is densely covered by long, somewhat spreading bracts, and of which the most 
glaucous extreme is A. salmiana glauca Becker (Monatsschr. Kakteenk. 8: 
150). An exceptionally broad-leafed form is var. cochlearis (A. cochlearis 
Jacobi, Abh. Schles. Ges. Vaterl. Cult. 1871: 151. 1871), known in Sicilian 
gardens as A. whitakeri. ; 

106. Agave mapisaga Trel., sp. nov.

*H. Bourgeau was a member of the French Scientific Commission of 1865-66. 
He had had previously wide experience as a botanical collector in the Old 
World, and his Mexican collection was an extensive one. It was gathered 
chiefly in the Valley of Mexico and in Veracruz. A large number of his 
specimens are in the U. S. National Herbarium. He died at Paris in 1877.

20 cm. wide and 200 cm. long, with brown or gray, straight or slightly recurved, 
grooved spine 8 to 10 mm. wide and 25 to 80 mm. long, this acutely pointed 
from the very base, and with heavily triangular teeth 30 to 60 mm. apart and 
5 to 8 mm. long, these with dilated bases, often from fleshy hummocks. 

Extensively planted in southern Arizona (Tucson) and California (Los 
Angeles) as A. americana, from which its unreflexed leaves and more acutely 
pointed, somewhat prismatic spine distinguish it. ° 
115. Agave americana L. Sp. Pl. 323. 1753. 

Native ?; type cultivated in Europe, probably originally from a Mexican 
hedge-row ; established freely about the Mediterranean. 

Leaves gray, acute, outcurved or reflexed at end, 15 to 20 cm. wide, 200 to 
250 cm. long, with brown, somewhat curved, conical spine 5 mm. wide and 
25 mm. long, and triangular, more or less recurved teeth 15 to 50 mm. apart 
and about 5 mm. long, on fleshy prominences. 

It is this plant, cultivated in the Azores, ete., from which the “pita” used 
in the drawn work of those islands is procured. Early records of the economic 
uses of ‘Agave americana” and “A. mexicana’ commonly refer to other species, 
such as A. fourcroydes and A. atrovirens.

Much planted. On the Mediterranean coast seedlings are said to be invari- 
ably green (var. viridis Trel. in Bailey, Stand, Cycl. Hort. 1: 235. 1914; A. 
ingens Berger, Hort. Mortolensis. 12, 360. 1912), and no doubt correspond to 
the normal type of foliage.

*The species is named in honor of Edward Palmer (1831-1911), an English- 
man by birth, who was for most of his life a resident of the United States. 
He spent many years in Mexico in botanical exploration, and his collections 
are surpassed in extent, probably, by those of no other collector. His work in 
Mexico began about 1870 and was continued until 1910. He collected chiefly 
in the northern states, but some of his plants were obtained as far south as 
Guerrero and Veracruz. His earlier collections were the basis of special 
reports by Gray and Watson, and many new species have been based upon his 
specimens.

REFERENCE: Uline, Bot. Jahrb. Engler 22: 421-431. 1896. 

Seandent plants, usually with large fleshy roots; leaves mostly broad and 
cordate, palmately 3 to many-nerved and reticulate-veined, entire or lobed; 
flowers small, usually dioecious, racemose or spicate; fruit a 3-valved capsule. 

It is difficult to determine which, if any, of the species should be included 
in the present treatment. Some of them certainly have large, more or less 
persistent stems, but this character is rarely shown in herbarium specimens. 
The writer has included most of the larger plants, although probably most of 
them should have been omitted. There have been excluded a number of species 
which are evidently wholly herbaceous.

* Alfredo Duges, a native of France, came to Mexico in 1853. For many years 
he held the chair of natural history in the college of the State of Guanajuato. 
He was a diligent student of the plants and animals of Mexico, and published 
many papers upon natural history. He obtained extensive collections of plants, 
many of which are in the Gray Herbarium, and a few in the U. S. National 
Herbarium. He died in 1910. The genus Dugesia, of the family Asteraceae, 
was named in his honor by Gray.

1. Casuarina equisetifolia L. Amoen. Acad. 4: 143. 1759. 

Commonly cultivated in Mexico and often growing without cultivation. 
Native of tropical Asia and Australia; naturalized also in southern Florida. 

Large pinelike tree, sometimes 20 meters high, with a trunk 1 meter in 
diameter, with slender verticillate spreading branches; bark gray; young 
branchlets drooping, pale, resembling the stems of Hqwisetwm, the leaves 
reduced to whorled scales; staminate flowers in slender terminal spikes; fruit 
conelike, 1 to 2 em. in diameter; wood very hard, strong, close-grained, flesh- 
colored or in age brown, its specific gravity about 0.98. “Pino” (Yucatan, 
Cuba); “ciprés” (Yucatan); “pino de Australia” (Cuba) ; “sauce” (Nica- 
ragua). Known in English-speaking regions as beefwood. 

A common and handsome tree in parks in Mexico. In regions where the 
tree is native the bark is used for tanning and dyeing, yielding a reddish or 
blue-black dye. The bark is used in medicine for its tonic and astringent 
properties. 


1%. PIPERACEAE. Pepper Family. 


The genus Peperomia is the only other Mexican representative of the family. 
Its species are mostly low herbs. Some of them may be shrubs, but there is no 
satisfactory evidence that they are. 


1. PIPER L. Sp. Pl. 28. 1753. 


REFERENCE: C. De Candolle in DC. Prodr. 16*: 240-388. 1869. 

Shrubs or small trees; leaves alternate, entire, stipulate; flowers perfect or 
unisexual, small, greenish, sessile in very dense terete spikes, or sometimes 
racemose; fruit a small berry. 

The species are widely distributed in the moist and tropical regions of 
Mexico, but they are more abundant farther south. They are separated by 
rather small differences, and, as so limited, most of them are of very limited 
distribution. In some localities the plants are used medicinally, for various 
purposes. The plants are more or less aromatic. The leaves are used for 
seasoning, and the fruit of some species is edible. Piper nigrum L., of the 
Hast Indies, furnishes the black pepper of commerce, which is widely used as a 
condiment. It is cultivated in the East Indies, Asia, Philippines, West Indies, 
and elsewhere. P. cubeba L., also of the East Indies, furnishes the cubeb 
berries of commerce, which are used in medicine for various catarrhal affec- 
tions. Piper betle L. is the betel pepper, whose leaves are chewed by the natives 
of the Pacific Islands... In South America some of the species have a wide repu- 
tation for the cure of snake bites. 

The species of Piper are most commonly known in Mexico by the name of 
“ cordoncillo.”

although some probably belong to other species, and doubtless most of them 
are applied to various species indiscriminately: “Santa Maria” (Tabasco) ; 
“acuyo,” “hoja de ajan” (Veracruz); “hierba santa” (Veracruz, Oaxaca) ; 


“santilla de comer” (Oaxaca, Reko); ‘ tlamapaquelite,” ‘ tianepaquelite,” 
“ tlanepaquilitl ” (Veracruz, Oaxaca; Nahuatl); “hoja santa;” “hoja de

Trees or shrubs; leaves alternate, stipulate, entire, dentate, or lobate, de- 
ciduous; flowers dioecious, in catkins; fruit a small capsule, the seeds bearing 
long white hairs. 

The following genera are the only ones of the family: 


5 Stamens numerous; bracts incised; disk cup-shaped; winter buds with several 


RCC eine m yeremaniWhs LAr teers CHOKE IS aA Cre eles Sie iad opt 1. POPULUS. 
Stamens usually less than 5; bracts entire; disk represented by one or two 
small glands; winter buds with a single scale______________ 2. SALIX. 


1. POPULUS L. Sp. Pl. 1034. 1753. 


The species of Populus are generally distinguished from those of Salix by 
their broad leaves, but one Mexican representative, P. angustifolia, has leaves 
as Narrow as those of some willows. 

The native species are widely used in Mexico as shade trees, for which 
purpose they are very satisfactory, since they start readily from cuttings or 
from large branches placed in the ground, and grow rapidly. They are not 
very long-lived and the trees are frequently killed by mistletoe (Phoraden- 
dron). The pistillate trees are not desirable as shade trees, for in the spring 
when the fruit is ripe the seeds fly everywhere through the air, filling people’s 
eyes and nostrils and becoming a general nuisance. This trouble may be 
avoided by planting only cuttings taken from staminate trees. 

Besides the native species, the white poplar, P. alba L., of the Old World, 
and its various forms (‘alamo blanco”) is cultivated in central and southern 
Mexico. It is distinguished by having the lower surface of the leaves covered 
with a dense white tomentum. P. nigra L., the black poplar, another Old 
World species, is said to be cultivated in Mexico.* 

The most common name for the species of the genus is “ Alamo.”

been stated by Bailey’ that this is a form of the Old World P. alba which has 
become naturalized in Baja California, but the writer is convinced from study 
of specimens that this is not the case. 


4. Populus tremuloides Michx. Fl. Bor. Amer. 2: 248. 1803. : 

Mountains of Chihuahua, Sonora, San Luis Potosi, and Durango. Widely 
distributed in the United States and in Canada (type locality). 

Usually a small slender graceful tree, but sometimes 12 meters high or even | 
up to 18 meters, the trunk sometimes 60 em. in diameter; bark thin, smooth, 
pale green or grayish; wood soft, weak, light brown, its specific gravity about 
0.40. “Alamillo” (Durango, Patoni). 

Large amounts of aspen wood are used in the United States for paper pulp. 
The tree is one of the first to spring up in lumbered or burned-over regions, and 
it often covers large areas. The Mexican specimens seen are all sterile. 
Probably they should be referred to P. aurea Tidestrom,’ but the status of that 
species is still uncertain.

Populus fremontii wislizent S. Wats. Amer, Journ. Sci. 111. 15: 3. 1878. 

Along streams at low altitudes, northern Chihuahua and Sonora. Western 
Texas to Colorado. 

Often 15 meters high, with a very thick trunk and large crown; bark pale 
gray, fissured; leaves 5 to 10 cm. long; wood soft, brownish, its specific gravity 
about 0.46. Commonly known as “délamo”; ‘ giiérigo” (Chihuahua). 

In the Rio Grande Valley the wood is much used for firewood, fence posts, 
and rafters of houses. It is not very good for fuel, since it burns almost like 
paper. The fallen leaves are eaten by cattle. This cottonwood is the most 
common shade tree of New Mexico. It was reported from Mexico by Hemsley 
as Populus balsamifera L., a species of more eastern and northern distribution. 
6. Populus dimorpha T. S. Brandeg. Zoe 5: 197. 1905. 

Along arroyos and streams at low altitudes, Sonora and Sinaloa; type from 
Culiacan. 

A large tree, often planted in parks; remarkable for the dimorphism of its 
leaves, those on the older branches ovate-deltoid, very long-acuminate, those 
on young shoots linear-lanceolate to ovate-lanceolate. 


7. Populus arizonica Sarg. Bot. Gaz. 57: 210. 1919. 

Populus arizonica jonesit Sarg. Bot. Gaz. 57: 211. 1919. 

Baja California to Chihuahua, Tamaulipas, and Puebla, chiefly in river bot- 
toms; Chiapas (?). Southern California to New Mexico; type from Arizona. 

Large tree, sometimes 25 meters high, with a trunk diameter of 1.5 meters; 
crown rounded, with spreading branches; bark light gray, ridged, or on young 
trees smooth. Generally known as ‘ alamo,” but also as “ chopo” (Chihuahua, 
San Luis Potosi) and “olmo” (Tamaulipas). 

The wood is used for fuel, carts and cart wheels, fence posts, water troughs, 
ete. P. arizonica jonesii (type from Valley of Palms, Baja California), to 
which most of the Mexican material belongs, is a form with longer pubescence 
than the type. 

8. Populus mexicana Wesm. in DC. Prodr. 16’: 328. 1864. 

Type collected between Tampico, Tamaulipas, and Real del Monte, Hidalgo. 

Leaves broadly ovate, 4.5 to 7 em. long, long-petiolate, abruptly long-acumi- 
nate at the apex. 

The writer has seen no material agreeing satisfactorily with the type collec- 
tion. 

9. Populus fremontii S. Wats. Proc. Amer. Acad. 10: 350. 1875. 

Baja California; Sonora(?). California and Nevada; type from Deer Creek, 
California. 

Large tree, sometimes 35 meters high, with a trunk 2 meters in diameter, the 
branches spreading and drooping; bark light gray and smooth on young trees, 
brown and ridged in old trees; wood soft, light brown, weak, its specific gravity 
about 0.48. “Alamo” (Baja California). 


*The species was named for Adolf Wislizenus (1810-1889), who came to the 
United States from Germany in 1835. He was one of the first of United States 
botanists to visit Mexico, having gone, by way of the Santa Fe trail, to Chi- 
huahua in 1846. He obtained in that State a large collection of plants, which 
were reported upon by Dr. George Engelmann in a book published by Wislizenus 
detailing his travels.

REFERENCE: C. Schneider, Bot. Gaz. 65: 1-41. 1918. 

The various species of willows are found in nearly all parts of Mexico, 
usually growing at the edge of water. They are often planted as shade trees. 
Salix babylonica L. (“ sauz lorén,” the weeping willow), an Old World species, 
with very long, slender, drooping branches, is sometimes cultivated also. 

The wood is used chiefly for firewood, but also for construction to a limited 
extent. In the United States it is burned for charcoal, which is of excellent 
quality, being used in medicine and as black crayon by artists. The bark is 
sometimes used for tanning, and the leaves as forage for stock. The flexible 
tough branches are employed for making baskets, and they were so used by 
many tribes of North American Indians. They are used also in Mexico as 
well as elsewhere in the manufacture of wicker furniture. ‘The bark and leaves 
contain tannin and salicin. The latter principle is a useful febrifuge, and was 
widely used before quinine came into general use. A willow decoction is still 
employed for treating fevers in Mexico in domestic practice, and other medicinal 
properties are attributed to the plants. 

The usual names for species of Sali# are “sauz” and “sauce.” The follow- 
ing ones are said to be applied to species which have not been determined by 
the writer: “Ahuejote” (Jalisco, Valley of Mexico) ; “ huejocote,”’ “ huexotl ” 
(Nahuatl); “tepehuexote” (Valley of Mexico); “ yaga-gueza” (Zapotec) ;

botanical collectors. From 1847 to 1851 he made very large collections in 
western Texas, southern New Mexico and Arizona, and Chihuahua and Sonora. 
These were studied by Gray, and many species of northeastern Mexico were 
first described from Wright’s collections. Later Wright obtained an extensive 
series of plants in Cuba, and also in Nicaragua and other regions. Sets of his 
plants are in the U. 8S. National Herbarium.

teeth. “Arbol de la cera” (Hidalgo, Oaxaca, Veracruz, ete.) ; “ huancanala ” 
(Veracruz, Oaxaca, ete.) ; ‘ chae olol” (Chiapas, Seler). 

Myrica lindeniana is considered a distinct species by Chevalier. It is said to 
differ in having the leaves dentate above the middle, those of M. mevicana being 
entire or dentate only at the apex. The writer has seen no specimens that are 
certainly referable to M. lindeniana, but in view of the fact that the leaves of 
M. mexicana are sometimes coarsely dentate, it does not seem probable that the 
former is a valid species. 

This is a well-known plant in Mexico because of the wax that is obtained 
from the fruit. The shrub often occurs in great abundance, forming extensive 
thickets, and the fruit can be gathered in quantity. It is boiled in water, 
whereupon the wax rises to the surface and is skimmed off. The crude wax is 
greenish, or often very dark from impurities, but it may be bleached or purified 
until it is nearly white. It is not uncommon in the markets of Mexico City. It is 
used for candles, which burn slowly, with very little smoke, emitting a pleasant 
balsamic odor. It is used also as a substitute for or adulterant of beeswax, 
and has been tested for making phonograph records. Small quantities have been 
exported. The aromatic leaves also contain wax, but only in small quantities, 

The wax is a popular remedy, taken internally, for jaundice and diarrhcea. 
A decoction of the root bark is said to be acrid, astringent, and in large doses 
emetic.

About a dozen other species of the genus (the hickory trees) occur in the 
United States. Their wood is very tough and is much used for articles in 
which strength and elasticity is needed, such as ax handles, wagon wheels, 
etc. The seeds of most species have an agreeable flavor and large quantities 
are eaten.

STANDLEY—TREES AND SHRUBS OF MEXICO. 167 


Large tree, sometimes reaching a height of 50 meters and a trunk diameter 
of 2 meters; bark light reddish brown, furrowed into narrow ridges; leaflets 
ovate or oblong-lanceolate, 8 to 15 em. long; fruit with a thin husk, the nut 
rounded, reddish brown, thin-shelled; wood hard, rather brittle and weak, 
close-grained, light reddish brown, its specific gravity about 0.72. The follow- 
ing names are reported from various parts of Mexico: ‘‘ Nuez encarcelada,” 
“nuez chiquita,’’ “nogal morado,” ‘‘ pacanero,” ‘“ nogal de nuez chica,” ‘“ nuez 
lisa.” 

The bark is said to have been-used in Mexico in the treatment of intermittent 
fevers and for dyspepsia. The pecan is grown extensively in the southern 
United States, and the nuts are an important article of commerce. The kernels 
have a very agreeable flavor and are eaten alone or in candies and other sweet- 
meats. Most of the cultivated forms have much larger nuts, with thinner 
shells, than the wild trees.

Numerous species of Alnus occur in the United States. The Mexican alders 
have often been determined as A. acwminata H. B. K., and there are many ref- 
erences in literature to the name, but that species, described from the Andes of 
Peru, does not occur in Mexico. 

The bark of the alders is astringent and rich in tannin. It is used in Mexico 
for tanning skins, giving them a red color, and it is employed also for dyeing 
skins, blankets, etc., furnishing various colors according to the substances 
combined with it. The Nueva Farmacopea Mexicana states that the leaves are 
used as poultices for wounds, an infusion of the bark as a lotion in cutaneous 
diseases, a decoction of the bark internally for scrofula and venereal diseases, 
and a decoction of the fruit as an astringent lotion for inflammation of the 
throat. 

The following vernacular names are reported, but it is impossible to deter- 
mine the species to which they are applied: ‘‘Aile” or “ayle” (Jalisco, Mo- 
relos, Oaxaca; from the Nahuatl, “ailitl”); “abedul’” (Veracruz, Oaxaca) ; 
“olmo del pais” (Veracruz, Hidalgo, Ramirez); “palo de Aguila” (Oaxaca, 
Reko) ; “ yaga-bizie’”’ (Oaxaca, Zapotec, Reko); ‘palo de lama” (Guatemala, 
Pittier). The Spanish name “ aliso” is used in New Mexico and in some parts 
of Mexico.

The Chihuahua specimens were referred doubtfully to A. glabrata by Bart- 
lett, but seem essentially the same as A. arguta. This species has been referred 
to A. acuminata H.-B. &., A. ferruginea H. B. K., and A. jorullensis castaneae- 
folia (Mirb.) Regel, none of which is known to occur in Mexico.

Ostrya mexicana Rose, Contr. U. S. Nat. Herb. 8: 292. 1905. 

Veracruz to Tabasco and Chiapas. Guatemala (type locality) to Costa 
Rica. 

Tree, 12 to 15 meters high or smaller, with thin, light brown bark; leaves 
ovate, doubly serrate; staminate flowers in slender catkins; fruits surrounded 
by bladder-like bracts, arranged in strobiles like those of common hops 
(Humulus lupulus L.). Commonly known as ‘“ guapaque.” 

This is very closely related to O. virginiana (Mill.) Koch, but seems fairly 
distinct. In the Guatemalan form the pubescence is slightly more copious 
than in the plants of Veracruz, but there appears to be no essential difference 
between the two. 

The wood of the ironwood is very strong, tough, and durable. It is used for 
railroad ties and other purposes. The bark is used for dyeing and tanning.

Veracruz to Jalisco and Chiapas. Guatemala; eastern United States and 
Canada, the type from Carolina, 

Tree, sometimes 12 meters high, the trunk up to 60 cm. in diameter, usually 
compressed or fluted, the bark thin, smooth, grayish; leaves oblong-ovate, acu- 
minate; staminate catkins 2 to 8 em. long; wood hard, light brown, very difficult 
to work, its specific gravity about 0.78. ‘“ Lechillo,’ ‘palo silo,” ‘palo ba- 
rranco” (Michoacin, Altamirano). 

Carpinus caroliniana tropicalis is a form with more copious pubescence than 
the type. Both forms of the American hornbeam occur in Mexico.

PREFACE. 


The present part of volume 23 of the Contributions is a second 
nstallment of the Trees and Shrubs of Mexico, by Mr. Paul C. 
tandiey, assistant curator of the United States National Herbarium. 
‘his portion of the work extends from the oak family to the bean 
amily, both inclusive. Some of the largest and most important 
roups of Mexican plants are included in the families here treated, 
yhich contain many species of economic value. The account of the 
aks has been prepared by Dr. William Trelease, of the University 
f Dlinois.

TREES AND SHRUBS OF MEXICO’ 


By Pau C. STANDLEY. 


22. FAGACEAE. Beech Family. 


The only representatives of this group native in Mexico are the oaks, which 
belong to the largest genus of the family. The Old World chestnut (‘‘castafio,” 
the tree; “castafia,’ the nut), Castanea sativa Mill., is said to be cultivated 
occasionally in Mexico, Oaxaca, and other states.

Trees or shrubs; leaves alternate, deciduous or persistent, entire, toothed, 
or lobed, the teeth and lobes often bristle-tipped; flowers monoecious, the 
staminate ones in slender catkins; stamens 6 to 12; pistillate flowers solitary 
or in small clusters; ovules 6, but only one maturing; fruit an acorn, sub- 
tended by an enlarged cup (involucre). 

The genus Quercus is very abundantly represented in Mexico; indeed, no 
other country has so large a number of species. In this region the oaks are 
found chiefly in the mountains. In northern Mexico the species grow at 
comparatively low altitudes, in the arid mountains, but. they occur also at 
high altitudes in the larger ranges, such as the Sierra Madre. In southern 
Mexico oaks are almost confined to the high mountains, but a few species 
occur near sea level. 

From an economic standpoint oaks are very important. The wood is of 
the highest quality, being very strong and durable, although these characters 
vary in different species. It is used for an infinite variety of purposes, 
especially where strength is desirable. It is highly valued for furniture and 
for the interior finish of buildings, for ship building, wagons, railroad ties, 
and many other purposes. As fuel, also, it is unsurpassed. No other group 
of hardwood trees furnishes wood which is so widely used, in Mexico as well 
as elsewhere. The bark, too, is important economically, being one of the 
most widely used tanbarks. Several species of southern Europe have very 
thick, corky bark, which furnishes the cork of commerce. 

The ieaves of oak trees are often punctured by insects, and as a result galls 
(“manzanitas de encina”) are formed. These are frequently of the most 
beautiful and bizarre forms, and often brilliantly colored. They sometimes 
contain as much as 60 or 70 per cent of tannic acid, and consequently they are 
excellent for use in tanning leather. They are widely employed also for 
making ink. 

Oaks are almost unsurpassed as shade trees in temperate regions. Because 
of their tough wood they are seldom broken by wind. Their broad tops give 
them a handsome appearance, and they are very long-lived. 

The acorns (“bellotas”), too, are of considerable economic importance, 
although less so now than formerly.2 In early times they were an important

food of the American Indians, especially those of California and certain parts 
of Mexico, and they are still employed to some extent. Acorns contain starch, 
fixed oil, citric acid, sugar, and astringent and bitter principles. Sometimes 
they are sweet enough to be eaten raw without preparation, but usually it is 
necessary to rid them of the bitter principle. This is done by shelling and 
skinning the seeds, then pounding them into meal. The meal is washed re 
peatedly in water and then boiled as a mush or baked as cake or bread. 
White oaks (subgenus Leucobalanus) have the sweetest and most palatable 
acorns and have been the most generally used. All the live oaks (such as 
Quercus virginiana, Q. pungens, and Q. oblongifolia) are said to have edible 
acorns, but the black oaks (subgenus Erythrobalanus) were not extensively 
employed. The Indians of the southeastern United States obtained from the 
acorns of Q. virginiana a sweet oil much used in cooking. In more recent times 
acorns have often been roasted and employed as a substitute for coffee, or 
as an adulterant of it. 

Oaks are of little importance in medicine. In Mexico the staminate catkins 
are reputed anodine and antispasmodic, being used as remedies for vertigo and 
epilepsy. The bark and acorns are sometimes used as astringents. 

One of the most interesting products of these trees is the lac, widely known 
in Mexico, which is produeed by certain scale insects, or Coccidae. This, pre- 
sumably, is produced on various species of oaks, and also upon trees and shrubs 
of other families. The following account, by Urbina,’ of its production upon 
Quercus reticulata, may be quoted here: 

“It seems worth while to mention here the manna which forms on Quercus 
acuminata H. B., an oak which grows at Medina, on the boundary between 
the States of Michoacin and Mexico, which was studied by Sr. D. Melchor 
Ocampo, who gave the tree the name of Quercus mellifera, its vernacular name 
being encina de miel. According to Dr. Oliva (Lecc. Farm. 2: 84), in May it 
produces an abundance of a globular rough substance, which turns black and 
resembles manna. Sr. Dr. D. Manuel M. Villada brought back from an ex- 
cursion which he made to Medina a branch of this tree, black as if the bark 
were covered with rubber, due to a fungus which had formed in such quantity 
that it gave rise to a thick layer, in whose midst appeared very fine threads, 
long and transparent. like caramel, and which, in my opinion, are produced by a 
Coccus or aphis which feeds on this sugary substance. The excess is emitted 
in threads whose peculiar form is due to the abdominal tubes of the aphis. 
The explanation of this seems to me to be the following: In the month of 
May there is an abundant secretion of glucose produced by the bark of the 
oak, which is taken advantage of not only by the aphis which make these 
caramel-like threads, but also by the fungus which attacks the bark. 

“Under the circumstances, I believe it desirable that a study be made of 
this product, which, in the opinion of Sr. Oliva, may be a manna, a presump- 
tion apparently justified by the existence of two organisms; the fungus and 
the Coccus, which develop simultaneously, using the same food—the glucose. 
And as this principle is the dominant one in manna, I believe with Sr. Oliva 
that this oak under favorable conditions produces this substance, which should 
be analyzed carefully, after visiting the place where the oak grows, and study- 
ing the manner of its formation, in order to comfirm or correct this view.” 

The vernacular names applied to the species of oaks can be given in only a 
few instances. Many names are found in literature, but the species have 
been so confused that no confidence can be placed in the determinations. The 
usual Spanish names are “encina” (live oak) and “ roble” (deciduous oak), 


' Naturaleza 7: 105-106. 1900. 


STANDLEY—TREES AND SHRUBS OF MEXICO. 173 


with various modifying adjectives. The following names also are reported 
for species not identified: “Alcornoque” (Oaxaca, Michoacain; this is properly 
the name for the Spanish cork oak); “ cucharitas,” “ peinecillo” (Oaxaca, 
Reko); “encina memelita”; “charrasquillo” (Durange, Patoni; shrubby 
species) ; “ encinilla” (Durango, Patoni; shrub, 40 cm. high or less). 

The usual Nahuatl word for oak is written ‘‘ahuatl,”’ “ ahoatl,” and “ aoatl”; 
the following variants are reported: “Ahoaquahuitl,” “ ahuaquahuitl,” or ‘ aua- 
quauitl ” (oak-tree) ; “ ahuatetz,” “ auatetz,” ‘“ ahuatetzmolli,” “ auatetzmulli” 
(live oak); “ahuacoztic” (yellow-oak); “ahuatzin pitzahuac” (narrow-leaf 
oak); “texmole” (Michoacan); “ ahuatezon” (Morelos, Mexico); “ ahuato- 
matl” (acorn, literally “ oak-tomato ” ; sometimes corrupted as ‘“ aguatomate”) 
Geographic names reiating to oak trees are: Ahuatepec, “ oak-hill”; Ahuachi- 
chilpa, ‘in the red oaks’’; Ahuatlfin, ‘‘ near the oaks.” 


Reko gives the following Zapotec names used in Oaxaca: “ Yaga-yoo,” 
“ yaga-reche,” ‘‘ yaga-xoo,” “ yaga-cino,” ‘“ yaga-zache’’ Belmar lists the 
following Mixe names: “Kook” (acorn); “sho”; “shokiup”; “ shotidnit” 


(acorn). Otomi names, according to Buelna, are “méttza” and “ndeza” 
(acorn). Gonzalez gives the Zoque name as “camay-cuy.”” A name reported 
by Ramirez from Michoacan, probably Tarascan, is “ tarecuen.”

*Henri Galeotti was born in France in 1814. He sailed from Hamburg for 
Mexico in 1835, reaching Veracruz in December. He spent six months at 
Jalapa, collecting living plants, especially orchids. He passed on to Vigas and 
Perote, and finally Puebla and Mexico. He botanized at various times in the 
state of Mexico, part of the time in company with Ehrenberg. In 1835 he 
spent two or three months in Hidalgo. At the end of that year he visited 
Querétaro and later Jalisco and Tepic, and in 1887 Guanajuato. He ascended 
Popocatepetl in June, 1837; in July he visited Michoacin, and in December 
Aguascalientes and San Luis Potosi. In April, 1838, he returned to Veracruz 
and made his headquarters at the German colony at Mirador. In August of that 
year, in company with Funck, Linden, and Ghiesbreght, he ascended the Pico 
de Orizaba, remaining with his companions for 11 days in a cavern on the 
mountain. In 18389 he visited Puebla and Oaxaca. In 1840 he returned to 
Hurope, where he become director of the Botanical Garden of Brussels. He 
died in 1858. Descriptions of some of the new species discovered were pub- 
lished by himself and Martens in the Bulletin de l’ Académie Royale de Belgique.

brown glabrescent buds as much as 12 mm. long; leaves large (4 to 7 em. wide, 
11 to 13 cm. long), densely creamy-tomentulose beneath. ovate to obovate or 
elliptic, acute or acuminate, rounded or obliquely truncate at base, moderately 
petioled, somewhat bristly-serrate at the end; acorn ovoid, 18 mm. in diameter, 
20 to 25 mm. long, one-third included, the half-round cup with blunt, rather 
loose scales. 

With long-acuminate low-denticulate leaves as much as 12 cm. wide and 22 
em. long it is Q. acuminata Mart. & Gal. (Bull. Acad. Brux. 107: 217. 1843). 
With blunt-pointed, rather deeply serrate and acute-based leaves 5 cm. wide

Ulmus mexicana Planch. in DC. Prodr. 17: 156. 1878. 

Veracruz, the type from Mirador; reported from Oaxaca. Costa Rica and 
Panama. 

Large tree, 15 to 40 meters high, with open crown, the branches ascending; 
bark gray, somewhat scaly; leaves deciduous, oblong-ovate, acuminate, serrate; 
flowers yellow; wood hard, heavy, strong, very tough, rather fine-grained, light 
or dark brown, sometimes with darker lines. “‘Olmo” (Oaxaca, Veracruz) ; 
“papalote,” “ cempoalehuatl” (Veracruz); “ira” (Costa Rica); ‘ ceniza,” 
“cenizo”’ (Panama). 

The wood is used in Mexico for lumber. The bark is astringent and is used 
for treating coughs. 

Planchon * has stated that this plant differs in no way from Ulmus. All the 
species of the latter genus, however, have a broadly winged fruit, while in 
Chaetoptelea there is no vestige of a wing, and this is a probably a sufficient 
basis for the maintenance of Liebmann’s genus. 


2. ULMUS L. Sp. Pl. 225. 1753. 

Sess¢ and Mocifio reported? Ulmus americana from Mexico. The plant so 
named (if the report is based on an actual plant) probably belongs to some 
other genus. 

The members of this genus (the elms) are perhaps the finest shade trees for 
temperate regions, although they are of slow growth. The wood of most species 
is extremely tough.

The following is the only species of the genus, which was named in honor 
of Senor Don Filemén L. Lozano, who assisted Pringle in his Mexican col- 
lections. 


1. Lozanella trematoides Greenm. Proc. Amer. Acad. 31: 236. 1905.

Shrub or small tree, 2 to 6 meters high or in some parts of its range still 
larger, the trunk occasionally 10 to 15 cm. in diameter; leaves ovate, finely 
serrate, 3-nerved, acute or acuminate, 5 to 12 cm. long, their pubescence vari- 
able in amount; flowers very small, greenish white, cymose; fruit small (about 
1.5 mm. in diameter), globose, green or reddish; wood light, soft, close-grained, 
light brown. ‘“Ixpepe” (Veracruz); “equipal’” (Michoacin); ‘“‘yaco de

“ecapuli” (Guatemala); ‘‘masaquila” (Venezuela); “memiso” (Santo Do- 
mingo); “palo de -cabra,” “ guacimilla” (Porto Rico). 


The bark contains very strong fiber. The species of this genus seem to be 
of little economic importance. 7. commersonii Blume, of Madagascar, is highly 
esteemed for medicinal purposes by the natives, and stomachic, astringent, 
febrifuge, diuretic, and antisyphilitic properties are attributed to it. 


5. CELTIS L. Sp. Pl. 1043. 1753. 


Large or small trees or shrubs, sometimes scandent, armed or unarmed; 
leaves deciduous or somewhat persistent, entire or dentate, often unequal at 
base; flowers small, the pistillate usually solitary and long-pedicellate; fruit 
globose, with thin flesh and a large seed. 

The fruit of all the species is sweet and edible, especially in the spineless 
species (hackberries or sugarberries), but the pulp is very scant. The Indians 
of some parts of the United States seem to have been very fond of it. They 
pounded the fruit fine, seeds and all, and ate it with fat or mixed with parched 
corn.”

Chihuahua to Baja California and southward. Central America, West Indies, 
and South America; southern Florida and western Texas. 

Shrub or small tree, 3 to 12 meters high, the trunk often 25 to 30 cm. in 
diameter, the branches armed with stout, usually recurved spines, long and 
spreading or clambering; branchlets often compressed; leaves ovate or oval; 
flowers greenish yellow; fruit 8 to 12 mm. long, yellow, somewhat angled, 
“Granjeno” (Veracruz and elsewhere) ; “ garabato blanco” (Sinaloa) ; “una

The leaves are very variable in shape and toothing. but their variations seem 
to offer no basis for specific segregation. The leaves of this and the follow- 
ing species are conspicuously domatiate beneath—furnished with cuplike shelters 
(for parasites?) in the axils of the veins. The fruit is edible. The specific 
name is derived from the fact that the fruit is eaten by iguanas, the common 
and characteristic lizards of the tropics.

Momisia pallida Planch. in DC. Prodr. 17: 191. 1873. 

Chihuahua to Baja California and Oaxaca. Arizona to western Texas (type 
locality). 

Densely branched spiny shrub, 1 to 6 meters high, the branches often long 
and recurved; leayes oval to oblong, obtuse or acutish; cymes few-flowered ; 
fruit 5 to 8 mm. long, yellow, orange, or red. ‘“ Granjeno” (Chihuahua, Du- 
rango, Nuevo Leon, Texas; often written “ grangeno’’); “ granjeno huasteco ”

This shrub often forms dense impenetrable thickets of considerable extent. 
The wood is good for fuel and fence posts. The fruit is edible, but somewhat 
astringent. The flowers are said to furnish'a good quality of honey. 

The pubescence of the branchlets is usually appressed but sometimes spread.

sometimes entire. The species has been reported from Mexico as Celtis tala 
Gill., a plant of South America. This is presumably the plant described from 
Mexico by Sessé and Mocifio* as Rhamnus grangenos, although it is doubtful 
whether that name is not referable rather to Celtis iguanaea.

5. Celtis reticulata Torr. Ann. Lyc. N. Y. 2: 247. 1824. 

Ccahuila to Baja California. Texas to Colorado and Arizona; type from 
the Rocky Mountains. 

Small or large tree, sometimes 15 meters high, with a trunk 50 to 60 
em. in diameter, but in arid places frequently only a shrub 8 meters high, the 
crown dense, broad, the branches often very crooked; bark white or gray, 
smooth on young trees, very rough in age; leaves often rounded-ovate, obtuse 
or acute, 3 to 7 cm. long; fruit red or orange, about 8 mm. in diameter; wood 
with a specific gravity of about 0.72. ‘Palo blanco” (Durango, Tamaulipas, 
Texas); “palo mulato” (Durango); “acibuche” (Chihuahua); “ cumbro” 
(Sinaloa) ; “palo duro” (New Mexico). 

The tree is usually too small and crooked to be of economic importance, but 
the wood is used for posts and for axe and hoe handles, and for ether similar 
purposes. The leaves are frequently covered with curious insect galls.

Often planted or left as a shade tree about dwellings; wood used in Mexico 
for carts and other objects, and in the United States, occasionally, for furni- 
ture and flooring; fruit edible, as in the other species, the pulp sweet but very 
scant. 

The Mexican specimens always have entire leaves. They do not seem spe- 
cifically separable from the eastern form, although the leaves are often broader.

“mora blanca,” “ mora deloma,” “ fustete,” “mora de piedra ” (Cuba) ; “ brasil ”

The wood is very durable and is used for furniture, interior finish, wheels, 
ete. Its most important use, however, is as a dye-wood; it furnishes a yellow, 
brown, or green dye, the coloring properties being due to two principles, morin 
or morindon, and moritannic acid. It is the fustic of commerce,’ long an im- 
portant article of export to Europe and the United States from tropical Amer- 
ica. Large quantities have been exported from Mexico, especially from Tabasco. 
It is usually prepared in the form of sticks 60 to 120 em. long and 7.5 to 20 cm. 
in diameter. The bark is used sometimes for tanning. 

Various medicinal properties are reported for this tree, in Central America 
and the West Indies. The bitter bark, with a disagreeable odor, is said to be 
astringent, tonic, and in large doses purgative; it has been used for venereal 
diseases. The ashes of the wood have been used in Jamaica for gout and 
rheumatism. The fruit is astringent and useful in the form of a gargle for 
sore throat and mouth. The root is reputed diuretic. In Nicaragua an in- 
fusion of the flowers is used for colds. When ripe the fruit is sweet and full 
of milky juice, and it is sometimes eaten.

young branches; flowers green, monoecious, the two kinds of flowers in sepa- 
- rate catkins; fruit a syncarp, composed of numerous small juicy 1-seeded drupes. 

One other species, M. rubra L., the red mulberry, is native in the United 
States. With regard to it, Havard says,” “ There is some ground for belief that 
our native Red Mulberry was cultivated [by the Indians], the fine quality and 
great quantity of the fruit being mentioned by De Soto and others.” Morus 
alba L., native of Asia, the white mulberry (“moral blanco’), with sweet and 
insipid, white or violet fruit is cultivated in Mexico. It has become natural- 
ized in the United States, where it was introduced at an early date as food for 
silkworms. It is said to have been introduced into Mexico for the same pur- 
pose about 1522. Mulberries of other species also have been used for feeding 
silkworms. Jforus nigra L., the black mulberry (“moral negro”), of Asiatic 
origin, is cultivated in Mexico for its large, juicy, well-flavored, red or black 
fruit.

The Spanish name for the mulberry fruit is “mora”; for the tree, “ moral”; 
the name “morera” is applied to the white mulberry tree. Asiain gives the 
Huastee name for mulberry tree as “ tzitzi.’ According to Belmar, the Mixe 
names are “ hamdek”’ (fruit) and “ hamdek-kiup” (tree).

Tree, 5.5 to 9 meters high; leayes oval-ovate, 5 to 15 em. long, bright 
green, cuspidate-acuminate; fruit at first red but finally black. The fruit is — 
known generally as “mora,” the tree as “moral”; “palo moral” (Oaxaca) ;_ 
“yaga-biyozaa”’ (Oaxaca, Zapotec, Reko); “brasil” (Costa Rica). 

The species is somewhat variable in leaf form and in size of fruit, but with 
the material available it does not seem necessary to recognize either of the 
segregates. This is perhaps the species to which Sessé and Mocifio* apply the 
name “ Morus tartarica,’ although it is not certain that they do not refer to 
one of the introduced species. It is probably to this tree that Sahagtén 
refers: ‘In this country [New Spain] there are mulberry trees. They are 
talled amacapulin [paper cherry]. This tree is smooth and branched. The 
branches are very numerous, and the leaves are crowded and green, a little 
paler beneath. It produces mulberries a little smaller than those of Castile.” 
In Ecuador the wood of this species is said to be valued for building purposes.

Small tree, 4.5 to 7.5 meters high, with a trunk 30 em. in diameter, the crown 
dense and compact, or often a shrub in Mexico; bark gray, furrowed, covered 
with small scales; fruit 1 to 1.5 cm. long, red or finally black; wood hard, close- 
grained, elastic, light brown, its specific gravity about 0.77. “ Mora,” “moral.” 

The wood is used to a small extent in Mexico by carpenters, and was employed 
by the Indians of Texas for bows. The fruit is rather sour and varies in size 
according to the amount of water the tree receives. It is sometimes found in 
markets. r 

This species may not be distinct from the preceding one. The leaves are 
very variable and often deeply lobed, especially on young shoots.

Trophis ramon Schlecht. Linnaea 6: 357. 1831. 

Tamaulipas to Sinaloa, Oaxaca, Veracruz, and Tabasco. Central America, 
Colombia, and the West Indies. 

Tree, 15 meters high or less, with brown bark, the trunk usually 35 to 40 em. 
in diameter; leaves short-petiolate, oblong to oval, 8 to 15 cm. long, short- 
acuminate, coriaceous, often very rough, entire or inconspicuusly dentate. 
“Ramon” (Veracruz, Tabasco, Cuba, Santo Domingo; a corruption of this 
name, “ramoon,’ used also in Jamaica); “confitura’” (Oaxaca, Reko) ; 
“huanchal” (Oaxaca); “leche Maria” (Oaxaca); ‘ ramoncillo” (Tabasco) ; 
“ramon de Castilla’? (Veracruz, Villada) ; “ cafecillo” (Nicaragua); “ram6én 
de caballos” (Cuba). 

The tree is much used in Mexico, as well as elsewhere, as fodder for domestic 
animals, the cut branches being often transported to some distance for the 
purpose. The fruit is said to be edible, although the flesh is certainly very 
seant. The bark contains tannin and has been used in medicine as an 
astringent. 

It may be that more than one species is included in the material referred 
here. The leaves are somewhat variable in shape and texture. The pistillate 
inflorescence is usually simply spicate, but it is sometimes branched. T. gla- 
brata Liebm.’, from the description, does not seem to differ essentially.

Large or small trees; leayes entire (in the native Mexican species) ; flowers 
minute, borne on the inner surface of a more or less globose receptacle, this 
succulent in age, with a very small opening at the apex, this closed by small 
scales, the receptacle subtended at the base by a lobed involucre. 

Many if not most of the Mexican figs are of very peculiar growth. They 
are hemiparasites; that is, they often begin their growth upon other plants, 
usually palms, germinating and developing a stem from which aerial roots 
descend to the ground and take root.? In this way the plants in their young 
stages are often vinelike. With age, the aerial roots increase in size and form 
a trunk which gradually envelops completely the host plant. The stems at 
first are flat, broad, and thin, and as they increase in size several will unite, 
assuming irregular and fantastic forms. Ultimately the host plant dies but 
often it persists for a long time, and it is not unusual to see the fronds of a 
palm rising from the crown of a large fig tree. Figs of this habit of growth 
are known generally as “‘matapalo.” Sometimes the plants begin their growth 
upon cliffs, developing their thin trunks against the rocks.

Large fig trees, too, often send down from their branches aerial roots which 
take hold of the soil and finally develop into trunks. In this way trees of the 
banyan type are formed, some of them of enormous size. 

Because of their broad, dense crowns and handsome foliage many of the 
Mexican figs make attractive shade trees. Some exotic species are cultivated 
for the same purpose. F. nitida Thunb., an Asiatic plant with small lustrous 
obovate leaves is seen frequently in parks, being known as “ laurel de la India,” 
“laurel,” and “Alamo extranjero.” A specimen of F. crassinervia Willd., from 
Puebla, was probably taken from a cultivated tree; the species is a West 


Indian one. F. religiosa L., of the East Indies (“laurel de India,’ “4lamo — 


cubano’), with very long-acuminate leaves, also is cultivated. fF. elastica 
Roxb., another Old World species, is frequent in parks and gardens, being one 
of the finest shade trees grown in the tropics. It is one of the sources of India 
rubber, and is the well-known rubber plant which is cultivated for ornament in 
the United States and elsewhere. Its leaves are larger than those of most 
Mexican species, and the fruit is of distinct shape, oblong rather than globose, 
as in most figs. The common edible fig, F. carica L. (‘‘ higuera,’”’ “ higo”’), is 


extensively cultivated in Mexico for its fruit, which under favorable conditions — 


is produced at all times of the year. It differs from all the American species 
in having lobed leaves. It was doubtless brought to Mexico at a very early 
date by the Spaniards. The Jesuits introduced the fig tree into Baja California 
in the eighteenth century, and it is said to have been the only fruit, except 
grapes, which was thoroughly successful there. 

The fruit of all the species is edible, but often the receptacles are so small 
and dry that they are not very palatable. They are a favorite food of many 
kinds of birds and of domestic-animals. 

The milky juice of the Mexican species yields a kind of rubber which might 


become of some commercial importance. This is said to have been used locally — 


for treating fractured bones and for similar purposes. Some of the South 
American species are said to produce commercial rubber. 

Few medicinal uses are reported for this genus in Mexico. The early in- 
habitants are said to have used the root, to which purgative properties are 
ascribed, in the treatment of fevers and chest affections, and the milky juice for 
ulcers. The juice is often applied to warts, but with what success is not stated. 
The juice of some of the South American species is reported to be extremely 
poisonous. 

The wood of the fig trees is soft and light and of little value. The large 
trunks, however, are often made into canoes. In preconquest days the bark 
was of great importance, for it was one of the sources of the bark paper used 
by the Aztecs for their records and correspondence. Some of this paper is 
still preserved in the ancient manuscripts. It is generally stated that the 
species used for the purpose was F’. petiolaris. This is, it is true, the species 
described by Hernfndez, but it is probable that other species were used indis- 
criminately. Plants of other families were used likewise for the same purpose, 
and it is now uncertain what one was most commonly employed. 

It was believed that the manufacture of bark paper in Mexico had become 
obsolete, but Professor Starr, of the University of Chicago, found a few years 
ago that the method of preparation was still known to some of the Otomf 
Indians of Hidalgo. He secured specimens of the paper and has published an 
account of its manufacture” He states that the trees used are “xalama” 
ae sP.), yt Jone? (Heliocarpus), “moral,” and “dragén.” The name 


Starr: In Indian Mexico, pp. 245-246, 259, 268. 


STANDLEY—TREES AND SHRUBS OF MEXICO. 207 


“moral” probably refers to some plant of the family Moraceae, and “ dragén” 
perhaps to a Jatropha. After being stripped from the trees, the bark is 
washed with lye water taken from the corn soaked for tortillas, washed in 
fresh water, thoroughly boiled, and split into thin strips. These the women 
arrange carefully upon a wooden plank and then beat with a stone until a 
sheet of paper results. The side of the sheet next to the board is smooth, 
the other somewhat rough. The paper is dried in the sun. The paper obtained 
from the “‘ moral” is white; that from “xalama” purplish. It is said that the 
bark of the “ule” (Castilla) also is used. 

Because of the purposes for which the paper is employed, its preparation is 
generally conducted with great secrecy. It is used for decorations in various 
ceremonies, especially those of pagan origin. More commonly, however, it is 
used for “‘brujeria’’ (witchcraft), and for this it is cut into “ mufiecos,” 
representing human beings, horses, and other animals, and these are employed 
to work injury to people and domestic animals, being buried in front of a house 
or in a corral. The mufecos are employed also for curing disease, applied 
directly to the affected part. 

This ceremonial use of the bark paper is the last remnant of a common 
practice of ancient times. Before the conquest paper banners were employed 
as offerings to the gods at certain feasts, and crowns of paper also were offered, 
and were worn by those who took part in the ceremonies. 

The vernacular names applied to the species of Ficus are very numerous, 
and many of them are listed under the species enumerated below. In Jalisco, 
according to Urbina, they are usually known as “camichin” or ‘“ zalate.” The 
former name, which is used elsewhere also, is applied to the species having 
smaller fruits than those known by the name “zalate.” The word camichin, 
he states, is written more properly coamichin (=coatl, snake+michin, fish= 
fish-snake=eel). This name was probably given because of the adventitious 
roots, which might be taken to resemble eels. A name widely used in Mexico 
for fig trees is amate; this is a modification of the Nahuatl word amatl, “‘ paper,” 
applied to the tree. It is interesting to note that the Tarascan word for paper, 
siranda, also is used as a name for the fig tree. The name “ macahuite” 
(Nahuatl, ama-cuahuitl=fig-tree ) is said to be used in central Mexico. The 
word amatl is preserved in such place names as Amatitlin, “among the fig 
trees’; Amatepec, “ the hill of the figs’; Amecameca, “ place where they wear 
fig shirts.”

Large or small tree with white trunk; leaves 6.5 to 15 em. wide; receptacles

although it is probable that most of them are applied to others also: ‘“ Tepe- 
amatl” or ‘“tepeamate’” (Guerrero; the former the Nahuatl term, meaning 
“ hill-fig ’’) ; “ tescalama,” “ tescalamate,” or “ texcalamate ” (Morelos, Durango, 
Guanajuato, etc.; in Nahuatl, tercalamatl=“ lava-fig,” this name, according to 
Robelo, given because the tree sometimes grows on lava rock); “palo chila- 
mate” (Oaxaca, Reko; from the Nahuatl, chil-amatl) ; “higuera” (Durango, 
Sinaloa); “palo Marfa,” ‘“ higuerén” (Sinaloa, Mexico) ; ‘“ higuerote,” ‘ tex- 
calama lechosa” (Sinaloa); “‘amate” (Oaxaca); ‘‘amacostic” (Morelos) ; 
““amate amarillo” (Morelos, Guerrero). 

This species has frequently been reported* from Mexico as FP. nymphacifolia 
L. That is a South American species, which is somewhat similar but neverthe- 
less quite distinct. 

This species is discussed by Hernindez? in a chapter entitled.“ De Amacoztic, 
seu Papyro lutea, seu Tepemat!, Sycomoro Saxatili Mexicana.” His remarks are 
as follows: “The Amacoztic, which some call Texrcalamatl, or rock-paper, and 
others Tepeamatl, is a large tree which has the leaves broad, almost round, 
thick and purplish like ivy, and nearly heart-shaped; the bark is on one side 
yellow inclining to green, and on the other red; it has the fruits on the same 
trunks, which are smooth like that of a fig tree; the fruit resembles small

figs; it is purple and full of small red seeds; the tree is fastened to the rocks, 
and is a wonderful thing. The leaves have no perceptible odor or flavor; their 
temperament is moist and cold. The decoction of the roots allays the thirst 
of those who suffer from fever, alleviates pains of the chest, is purgative and 
vomitive, and it is prepared by boiling three ounces of the roots with three 
pounds of water until the half is consumed; its milk cures sores of the lips 
and chronic ulcers. The tree grows in mountainous and rough places about 
Chietla, embracing the rocks, as I have said, and as the name itself indicates. 
There is another kind that has the same name and temperament, which, they 
say, serves only for furnishing straight, smooth poles.” Hernandez also gives 
two easily recognizable figures of the plant (pp. 82, 409). 
- Dr. Fernando Altamirano, quoted by Urbina,’ describes the gum or rubber 
obtained from this -(and probably also from other) species of Ficus as follows: 
“The commercial Texrcalama appears as rounded masses of variable dimensions. 
This substance is elastic and adhesive and very ductile, gray in color, and 
capable of being formed into membranes as delicate as soap bubbles, being in 
this state white and transparent; exposed to the air it hardens and assumes 
a yellow tint, for which reason it should be kept in vessels full of water. In 
boiling water it softens and becomes more sticky. 

“Tts density is greater than that of water; its odor is urine-like, and it has 
scarcely any taste. 

“In its analysis I found 15 per cent of caoutchouc, 55 per cent of a resin 
soluble in alcohol, and 5 per cent of a resin soluble in ether.” 

This gum is used by surgeons and others in Mexico for treating broken bones, 
hernia, ete.

This is presumably the tree described by Clavigero” as “ anab4,” in the fol- 
lowing words: “Anabdd is the name of a fruit similar to the fig, and of the tree 
on which it is borne. The latter is large, the bark of its trunk and branches 
whitish like that of the fig tree, and the fruit similar in color and shape to 
the early figs but smaller, less juicy, and without the sweet flavor of our figs. | 
Nevertheless the Californians esteem it so highly that when they hear of an 
anabd with ripe fruit they go to hunt for it and gather a supply of the fruit, 
even though it may be four or five leagues distant. The wood of. the anabd is 
absolutely useless, and the roots are usually broader than thick, for since the 
tree grows among rocks, it introduces its roots into the clefts, or, in default of 
these, extends them over the rocks themselves. In Mexico, where it is known 
by the name of zalate, it fruits better and attains a larger size.”

One of the handsomest of Mexican trees, often with an immense crown of 
dark green leaves. It has been reported from Mexico as F’. ligustrina Kunth & 
Bouché, a South American species. The fruit is usually tinged or spotted with 
red or purple; it is sweet and much eaten by children and birds, and some- 
times it is sold in the markets. 

Urbina’ considers that this is the “amazquitl” of Hernandez, who speaks 
of the value of the tree for shade, and states that a decoction of the root bark 
was given to fever patients. The “hoeiamatl” of Hernandez is perhaps the 
same species; this was employed as a remedy for various skin diseases and 
for pains and sourness of the stomach. Another wild fig described by Hernandez 
under the name “itzamatl” may also be Ficus padifolia. This, Hernandez 
states, was called “‘ higo de Indias” by the Spaniards.

Tree, sometimes 30 meters high, with a trunk a meter in diameter, the crown 
broad and dense; bark gray; leaves bright green, glabrous, entire; flowers uni- 
sexual, in dense globose pedunculate heads; fruit subglobose, yellow or orange, 
containing a single large seed about 12 mm. broad. “Ramén” (Yucatan,

(Guatemala, Honduras). 

The wood is said to be white, or sometimes grayish or tinged with flesh solawl 
compact, hard, and fine-grained; it is used in carpenter work. The tree is 
valued highly for forage, the branches being cut and fed to different kinds of 
stock, and the fallen leaves are eaten greedily by cattle. The tree is oiten 
planted for this purpose, and in some parts of Mexico it is a very important 
forage plant. The milky juice is reported to yield a kind of rubber, and is used 
as a calmant in asthma. It is reputed also to increase the flow of human milk, 
this probably a relic of the old medical theory of signatures. The seeds are 
said to be fattening for cattle, which are fond of them, and they are used also 
as human food. For the latter purpose they are boiled or roasted, and eaten 
alone or mixed with sugar, honey, or corn meal. They have a flavor resembling 
that of chestnuts and are very nutritious. The seeds are sometimes roasted and 
used as a substitute for coffee.

Tree, attaining a height of 20 meters or more, the trunk grayish, nearly 
smooth; leaves distichous, deciduous, short-petiolate, oblong or oval-oblong, 
25 to 40 cm. long, cordate at the base, acuminate at the apex, copiously 
pubescent; flowers monoecious, the 2 kinds on separate receptacles, the stam- 
inate receptacles 2 to 2.5 cm. broad, bearing numerous flowers; fruiting recep- 
tacles 4 cm. or more in diameter, contorted, the fruits becoming fleshy and 
brick-red. “Arbol del hule”; “tarantaqua” (Michoacin, Leon); “hule” 
(the rubber; sometimes written “ ule”; derived from the Nahuatl olli or ollin) ; 
“cuauchile.” Robelo gives the Nahuatl names for the tree as “ olcagiiite,” 
“ulcuagiil,” “ oleuahuitl,’ and “ ulcuahuitl.” 

This is one of the best-known trees of Mexico, being the principal source 
of commercial rubber in Mexico and Central.America. The rubber is obtained 
from either wild or cultivated trees. The Castilla grows wild chiefly in the 
states of Chiapas, Tabasco, Yucatin, and Veracruz, usually at altitudes of 
700 meters or less. It is reported also from Campeche, Oaxaca, Guerrero, 
Michoacan, Colima, Jalisco, Hidalgo, Sinaloa, and Tamaulipas. Cultivation of 
the rubber tree was begun in the State of Chiapas about 50 years ago, but 
only in an experimental way, and it is only in recent years that cultivation has 
been carried on upon an extensive scale. The details of rubber production 
are so numerous that they can not be treated here, but those interested in the 
subject should consult the paper by Cook, listed above. 

Like other plants of the family Moraceae, the rubber tree has milky juice, 
and this is the source of the rubber. The juice is obtained by tapping the trees. 
It coagulates upon exposure to the air, but various substances are sometimes 
added to hasten coagulation. In British Honduras the pounded stems of 
morning-glory (Calonyction) are said to be used for this purpose. The early 
inhabitants of Mexico were well acquainted with the crude rubber, using it 
to make balls for games, for bottles, and for waterproofing coats, hats, shoes, 
and other objects. 

The wood is white and moderately heavy. The bark is beaten out by some 
of the Indians of tropical America, and the fabric thus obtained is used for 
clothing and blankets. In Mexico the bark is said to have been one of the 
sources of paper. 

Hernfindez was probably the first to give an account of the Mexican rubber. 
tree. He gives a fairly accurate figure, and the following account, in a chapter 
entitled “ De Holquahuitl, seu Arbore Chilli?” : “ Holquahuitl is a tree of which 
there are two sorts. The one produces a large, smooth, yellow stem, full of 
soft pith; whitish flowers; very large leaves; and star-shaped disks, pale but 
becoming red, clinging to a stalk and crowded with fruits like Pontie nuts, 
which are covered with a whitish and yellow skin and have a bitter flavor. The 
other sort has leaves like Malus Medicus, but larger; the bark of both trees is 
bitter. The latter grows in Michoacfin, where it is cal’ed tarantaquam. The 
first is called Mecatlani and yhulapae. The bark is warm in the third order 
and slightly lubricous; its infused decoction is good for dysentery. When cut 
it yields a gum, called Holli by the Indians, which is at first milky, but soon 
yellow, and finally black, if it is smeared on the bodies of those who gather it. 
It is so resilient that balls fashioned from it bounce like hand-balls, and it is 
useful for many other purposes. For it evokes the urine uncommonly, cleanses 
the womb, and corrects sterility. * * * Added to food it fattens, and com- 
pounded with those creatures which are called Azin, it is said to engender a 
certain agility to the body, and to soften the bones so that men are able to

turn and twist this way and that, and to handle the body like contortionists; 
and it excites venery, it allays colics, applied as a plaster it relieves the 
bowels, appeases thirst, and, burnt, it dissipates ulcers. This is that noble 
gum with which the Indians once were wont to play the game called Bathei, 
wonderful to see, which, by the agency of Cortés, the people of Spain also were 
enabled to witness years ago. The leaves of the tree, dried and bruised, are 
said to destroy lions and other animals.” 

According to Sahagin, “ hoarseness is cured by rubbing the throat with wlli, 
drinking honey, and sniffing a few drops of honey up the nose. * * * The 
gum is very medicinal and is used for almost all diseases. It is a remedy for 
the eyes, for abscesses, and for suppuration. It is taken with cacao. It is 
useful for the stomach and intestines, internal putrefaction, and constipation.” 
The rubber was employed also for holding broken bones in place, and for similar 
purposes. 

Several other species of Castilla are found in Central America. Some Mexi- 
can specimens have been reported as C. guatemalensis Pittier,* but the pres- 
ent writer has no reason for believing that more than one species occurs in 
Mexico.

Castilla gummifera (Bertol.) Pittier; see Contr. U. S. Nat. Herb. 20: 34. 1917. 

*The genus is named in honor of Bernardo de Sahagfin, a Franciscan friar 
of Spanish birth who came to Mexico as a missionary in 1529, Here, as Prescott 
states, “he distinguished himself by his zeal, the purity of his life, and his 
unwearied exertions to spread the great truths of religion among the natives.” 
He wrote a “ Historia Universal de Nueva Espafia,” the material for which 
he obtained directly from the native people with whom he was continually 
associated. This work he composed in the Nahuatl language, which he could 
both write and speak with great fluency. It was feared by the other members 
of the order that the publication of the work would keep alive in the natives 
too vivid an impression of the superstitions which it was the duty of the 
Christian church to eradicate, and consequently the permission to print the 
manuscript was refused. It was not until 1830 that SahagGn’s history was — 
actually printed. Besides the other matters of which it treats, the book con-— 
tains much information regarding the plants of Mexico. Sahagfin’s work is 
one of the most important of those dealing with Mexican antiquities, and is “ 
unique in the method of its preparation. The author lived to an advanced age, — 
and died in the capital in 1590. 


STANDLEY—TREES AND SHRUBS OF MEXICO. 217 


not numerous or very satisfactory, and it is doubtful how many species occur 
in Mexico. 

The trees grow very rapidly. Their hollow trunks are generally inhabited 
by pugnacious ants. The trunks are often cut in two and used as troughs to 
conduct water. Many of the native inhabitants of tropical America used them 
also for making a kind of trumpet, and the soft spongy wood was employed as 
tinder. In Brazil the wood has been used for making paper. The bark con- 
tains a tough, coarse fiber used for cordage and for mats and for a kind of coarse 
cloth by the Indians of Central and South America. The sap yields rubber, 
but the quantity obtained by tapping is too small to be of commercial impor- 
tance. It is said that the Indians sometimes ate the pith and that cattle eat 
the leaves and fruit. The fruit is eaten also by birds. 

Various medicinal properties are ascribed to the plants. In Mexico the juice 
is used as a caustic for the treatment of ulcers and the removal of warts. In 
South America and the West Indies it is used for dysentery and venereal dis- 
eases, and a decoction of the young leaves for dropsy, liver affections, and 
asthma. The ashes, according to Barham, were employed as a remedy for 
dropsy. It is said, in addition, that the plant possesses the properties of digi- 
talis, although its toxicity is relatively low. 

According to Cook’ Cecropia peltata is known in Porto Rico as “ yagrumo 
hembra,” because of the fact that it is popularly believed to be the female plant 
of Didymopanar morototoni, which is known as “ yagrumo macho.” 

The trees of the genus Cecropia are first described by Oviedo’? (Lib. VIII, 
Cap. X), under the name “ yaruma.” He states that the Indians valued them 
highly as a remedy for wounds. 

The following vernacular names are reported for the species: “ Guarumbo ” 
(Valley of Mexico, Oaxaca, Tabasco, Chiapas) ; ‘* guarumo” (Tabasco, Chiapas, 
Veracruz, Costa Rica; the word, according to Pittier, is probably of Cuban or 
Haitian origin); “chancarro” (Veracruz, Oaxaca); ‘ coilotépalo,” ‘“ coilota- 
palo” (Valley of Mexico); “saruma” (Michoacin, Valley of Mexico) ; 
“euarima” (Tabasco, Chiapas).

The fruit is said to be edible. In Yucatéin the shrub is planted for hedges. 
The hairs sting the flesh severely and sometimes cause painful sores. The 
branches are said to be used sometimes in Colombia as a rubefacient, and the 
fiber separated from them is employed in Cuba and elsewhere for making rope 
and twine. According to Grosourdy,* the root has been used in Porto Rico as 
a popular remedy for gonorrhoea, and the juice of the leaves for chills in in- 
termittent fevers, while diuretic properties are ascribed to the plant.

_ According to Reko, the Nahuatl name is “xio-patli” (ziotl, syphilis; patli, 
remedy, medicine). He states that the plant is still used by the Indians of the 
Sierra de Jufrez as a remedy for syphilis. Sessé and Mocifio state that the 
shrub was sometimes planted for hedges. Palmer reports that in Durango it is 
employed to cure the effects of poison ivy (Rhus toricodendron and related 


species).

A few herbaceous species occur in Mexico besides those listed below. ‘The 
best-known species of the genus is the ramie plant (‘‘ ramié,” “‘seda vegetal”’), 
Boehmeria nivea (1...) Gaud., a large herb or small shrub which has been cul- 
tivated in Mexico as well as elsewhere for its fiber. It differs from the native 
Mexican species in having the leaves densely white-tomentose beneath. The 
original home of the plant was probably China, but the species is now widely 
dispersed in tropical regions.

“Palo de zorrillo” (Oaxaca). 


27. LORANTHACEAE. Mistletoe Family. 


Shrubs, sometimes very small, parasitic upon the branches of trees or shrubs, 
usually green but often red, brown, or yellowish and without chlorophyll; 
leaves mostly opposite, entire, thick and leathery, frequently reduced to scales, 
estipulate; flowers large or small, perfect or unisexual ; fruit a l-seeded berry. 

The pulp of the fruit is extremely viscid, and if it comes in contact with 
any object it can not be separated from it without great difficulty. The fruit ; 
is eaten by birds and it is largely by their agency that the seeds are trans- 
ported from one host to another. It is said that in Brazil a kind of rubber 
has been extracted from the fruit, and that the leaves are used for tanning. 

When one of the plants of this family is removed from its host there is 
exposed upon the latter a curious structure which often assumes a flower-like 
form. These “ wood flowers” or “ flores de madera” are well known in some 
parts of tropical America, and various superstitions are associated with them.

spike. 

Mistletoe plants are much used in the United States for Christmas decora- 
tions, and on this account are of some commercial importance. The American 
mistletoes are different from the true mistletoe of Europe, Viscum album L., but 
some of them are similar to it in general appearance. The Spanish names 
applied to the European mistletoe are “ muérdago,” ‘liga,’ and ‘ visco,” words 
adopted in Spanish America for the native plants of the same family. The 
species of Phoradendron often occur upon trees in such abundance as ultimately 
to kill them. The fruit of some species has been reported as poisonous, but that 
of other species is said to be edible. The species apparently are little used 
in domestic medicine. The Coahuilla Indians of southern California are said 
to use the dried and powdered stems of one species (growing on Juniperus) as 
a remedy for saddle sores on horses. Ramfrez gives the names applied to 
various species of doubtful identification as ‘‘ cabellera,” “liga,” “ visco cuer- 
cino,” and “ chachahua.”

*Pi. Nov. Hisp. 51. 1887. 

*Named in honor of Thaddeus Haenke (1761-1817), a Bohemian. He was 
to have accompanied the Malaspina expedition executed during the reign of 
Charles III, but he reached Cadiz the day after that organization had set sail. 
He took another ship and sailed for Buenos Aires, proceeding to Chile, where 
he joined Née, and with him journeyed to Mexico. Haenke’s Mexican collec- 
tions were made along the road from Acapulco to the City of Mexico. He died 
in Bolivia. His specimens are chiefly at Prague and Vienna. Presl published 
two volumes under the title ‘“‘ Reliquiae Haenkeanae,’ based upon his col- 
_lections.

2. Ximenia americana L. Sp. Pl. 1193. 1753. 

Veracruz to Colima, Chiapas, and Yucatan. Florida, West Indies, Central 
America, South America, and in the tropics of the Old World. 

Spiny shrub or small tree, in some parts of its range 6 meters high; bark 
smooth, reddish, very astringent; leaves oblong or elliptic, 3 to 7 cm. long, 
pale beneath, rounded at apex; flowers yellowish white, fragrant; fruit yellow, 
subglobose, 1.5 to 2 em. in diameter, with peculiar odor and acid flavor; wood 
hard, tough, close-grained, yellow, its specific gravity about 0.92. ‘‘ Xkuk-ché”

“ciruelillo” (Cuba); “ manzanilla” (Guatemala, Honduras); “albarillo del 
campo” (Argentina). 

The fruit, which resembles a plum in appearance, is edible, either raw or 
cooked. It is stated that oil has been extracted from the seeds in Brazil. The 
fruit is said to have purgative properties, and Grosourdy states that a sirup 
made from it is used in the West Indies for dropsy, rheumatism, etc. The 
plant is seldom large enough to furnish wood of importance, but the wood has 
sometimes been employed as a substitute for sandalwood (Santalum), which 
it somewhat resembles. In Florida and the British West Indies this species 
is known under various names, such as “hog plum,” “ tallow-wood,”’ “ moun- 
tain plum,” “ false sandalwood,” and “ wild olive.” 


8. Ximenia parviflora Benth. Pl. Hartw. 7. 1839.

and slender; leaves oblong or obovate; fruit globose, yellow. “ Ciruelillo” 
(Guanajuato). 

The fruit is edible. 


*The genus was named in honor of Francisco Ximénez, a native of Luna in 
the Kingdom of Aragén. In the early years of his life he was a soldier, and in 
1605 he came to New Spain. He became a lay brother of the Convento de 
Santo Domingo de México February 25, 1612. The date of his death is not 
known. In 1615 there was published in the City of Mexico under his author- 
ship a volume entitled ‘‘ Quatro libros de la naturaleza y virtudes de las plantas, 
y animales que estan receuidos en el uso de medicina en la Nueva Espana, y la 
méthodo, y correcci6n, y preparacién, que para administrarlas se requiere con lo 
que el Doctos Francisco Hernandez escriuié en lengua Latina.’ This was re- 
printed at Morelia in 1888. Ximénez’s work is not a mere translation of Her- 
nandez, but contains much original information upon Mexican plants.

In coastal thickets, Tamaulipas to Yucatén and Sinaloa. Florida, West 
Indies, Central America, and northern South America. 

Shrub or tree, sometimes as much as 15 meters high, with a trunk a meter 
in diameter, but usually much smaller, densely branched; bark thin, smooth, 
brown; leaves about 20 cm. wide, very thick, the veins often red; flowers 
white; fruit purple, 1 to 2 cm. in diameter, in long dense heavy racemes; 
wood hard, dark brown, taking a good polish, its specific gravity about 0.96. 
“Uva de la playa” (Tamaulipas, Veracruz, Venezuela); “uva de la mar” 
(Tamaulipas, Yucatén, Oaxaca, Porto Rico); “uvero” (Tamaulipas, Cuba) ; 
“uva” (Yucatin, Veracruz, Santo Domingo); ‘“manzano” (Sinaloa); “uva 
caleta’’ (Cuba); ‘‘papaturro” (Costa Rica); “uvero de playa” (Panama, 
Costa Rica); “uvilla’ (Santo Domingo). 

In Florida and the British West Indies the plant is known as “ sea-grape.” 
“ nigeon-wood,” ‘ horsewood,” and ‘‘ hopwood.”’ The wood is highly esteemed 
in tropical America for cabinet work, and is used also for fuel. It is said 
to yield a red dye. The roots are astringent and have been employed as a 
remedy for dysentery. The fruit is edible, with an acidulous, somewhat as- 
tringent flavor, and in the West Indies it has been fermented, with sugar, to 
produce an alcoholic drink. Febrifuge properties are attributed to the bark. 
The shrub is often planted (as in Florida) for ornamental purposes, for the 
large thick leaves are of striking and handsome appearance. It grows readily 
from cuttings. 

The first account of the plant, probably, is that given by Oviedo (Lib. VIII, 
Cap. XIII), who says: ‘The Christians give the name wvero to the tree the 
Indians call quiabara. This is a fine tree, with good wood, especially for mak- 
ing charcoal for blacksmiths and silversmiths; as they are trees with spread- 
ing tops, and not straight, although the branches are thick and the wood 
strong, they are useless for construction of houses, but may be employed for 
butchers’ blocks and shoe lasts. The wood resembles that of madrono, for it 
is red, but it is stronger. The fruit consists of thin racemes of grapes, sepa-

rated from each other, rose or purple in color, and good to eat, although the 
stone is very large in proportion to the size of the fruit and the amount of 
flesh ; the largest are the size of a filbert. The leaves are like those illustrated ; 
they are so different from other leaves that I have shown them here. The 
largest of these leaves are a palm broad or larger, and some are smaller 
At the time that wars were going on in Hispaniola and the other islands 
and on Tierra-Firma, as the Christians did not carry with them paper and 
ink, they used these leaves like paper. The leaves are green and thick as those 
of ivy; the veins are red or purple and fine, and with a pin or sharp point one 
can write anything on them, from one end to the other, while they are green 
and freshly cut; the letters resemble white scratches and stand out so well from 
the face of the leaf that they are easily legible. Thus written upon, the leaves 
were sent by an Indian wherever the Spaniards wished them to go. Although 
the midvein of the leaf is rather large, the other veins are so small that they 
do not interfere with the writing.”

A very showy and handsome plant, and cultivated for this reason not only in 
Mexico but in many other regions. In general appearance it suggests Bougain- 
villea, and is equally handsome. It is a rapid grower and remains in bloom a 
long time. In Florida it is known as “ Confederate vine.” The flower clusters 
serve as tendrils for the support of the plant, and shorten themselves by bending 
at the joints in a zigzag form. The roots bear tubers which are usually small, 
although they are said sometimes to weigh as much as 15 pounds. They are 
edible and have a nutlike flavor. For an illustration of this species see Contr.

meal in salted water. The various species of Atriplex were rather important 
food plants among many of the Indians of the arid portions of North America. 
Among the Pimas of Arizona the young shoots, which have a salty flavor, were 
boiled and eaten. The same tribe made use of the seeds (presumably includ-— 
ing also the bracts), cooking them in pits over night, then drying and parching 
them and storing for winter use. Seeds so preserved were eaten as pinole—a 
mixture of the ground seeds with water. The Pimas used the powdered root as 
a dressing for sores.

34, ALLIONIACEAE. Four-o’clock Family. 


REFERENCE: Standley, Allioniaceae, N. Amer. Fl. 21: 171-254. 1918. 

Shurbs or trees, sometimes scandent; leaves opposite (in the genera listed 
here), entire; flowers small and usually inconspicuous; corolla none. 

Many herbaceous representatives of the family occur in Mexico. Bougain- 
villea spectabilis Willd., a native of Brazil, is a favorite ornamental plant in 
- Mexico. It is a tall spiny climber with alternate leaves, the small flowers being 
borne on large, showy, purplish red bracts. It is known in Mexico by the fol- 
lowing names: “Azalea de guia,” ‘*‘ bugambilla,’” ‘ bugevilla,’ ‘ bombilla,” 
“bugavilea,’ ‘ hernandiazéa,’ ‘‘camelina.” Another well-known cultivated 
plant of the family is the four-o’clock, Mirabilis jalapa L., known in Mexico as 
“arrebolera,” “ maravilla,” ‘Don Diego de noche,” and ‘** trompetilla.”

‘The genus was named in honor of Luis Née, a Frenchman by birth but a 
Spaniard by naturalization, who was an associate of Malaspina on his voyage 
around the world (1789-1794). He collected chiefly in South America, but 
also visited Mexico, landing at Acapulco and journeying to the capital, in com- 
pany with Haenke. His collections are at Madrid.

and in herbarium specimens they retain their viscidity indefinitely. The fruits 
adhere easily to the feathers of birds, sometimes in such abundance as to 
prevent their flying.

Known in Jamaica as “ guinea-hen weed.” Probably as a result of its strong 
and characteristic odor, the plant has been much used in domestic medicine. It 
is reputed to have diuretic, sudorific, expectorant, antispasmodic, and depura- 
tive properties, and has been used as a vermifuge, emmenagogue, and abortefa- 
cient, and for toothache (the roots inserted in cavities in the teeth), fevers, 
rheumatism, paralysis, venereal diseases, hysteria and other nervous diseases, 
hydrophobia, and scorpion stings. Palmer’s notes indicate that in Sinaloa the 
leaves are bound upon the forehead to relieve headache, and that the powdered 
roots are used as a snuff for nasal catarrh. It is stated that when cows eat the 
plant an alliaceous flavor is imparted to their milk. Descourtilz reports that in 
the West Indies the roots were placed among woolen goods to protect them from 
insects.

Nearly throughout Mexico. Widely distributed in tropical America. 

Suffrutescent, up to 1 meter high, sometimes wholly herbaceous; leaves petio- 
late, ovate, acute or acuminate, bright green; flowers small, white or greenish, 
racemose ; fruit a small, 1-seeded, red or orange berry. ‘‘ Coral” (various locali- 
ties) ; “ coralito,” ‘“‘ coralillo’’ (Durango) ; “‘ hierba mora,” “ saca-tinta,” “ cora-

“ojo de raton,” “coralitos” (Cuba); “ pimpin,” “ pinta-pinta” (Colombia) ; 
“sangre de toro” (Argentina, Uruguay); “ caimancillo” (Santo Dominge). 

The fruit is full of blood-red juice, which yields a red dye. The leaves are 
said to be used for catarrh and for treating wounds. The fruit is reported 
to be edible. Sometimes known as “ rouge-plant.” 

R. portulaccoides Nutt., with slightly larger flowers, and R. purpurascens 
Schrad., with purplish flowers in long stiff racemes, are recognized by Walter 
as distinct species, but they do not appear to differ essentially from the eommon

5. Clematis rufa Rose, Contr. U. S. Nat. Herb. 10: 95. 1906. 

Known only from the type locality, between Tenejapa and Yatalon, Chiapas. 

The plant differs from C. grossa only in its entire leaflets, and additional 
material is necessary to determine its claim to specific rank. This and the 
following species are very closely related, and it is probable that they are all 
forms of a single one, C. dioica.

Very variable in pubescence and shape of the leaflets; flowers often in large 
showy panicles; fruit conspicuous because of the feathery tails, these 3 to 6 
em. long. ‘“ Cabeza de vieja” (Chiapas) ; “barba de viejo” (Tabasco, Michoa- 
can, Valley of Mexico, Costa Rica, Guatemala, Nicaragua) ; “barbas de chivo”

(Mexico) ; “ chilillo” (Michoacan) ; “ chilillo de cerro” (Hidalgo) ; “ cabellos 
de angel” (Guatemala, Costa Rica, Cuba, Porto Rico); ‘ crespillo” (Nica- 
ragua). 

Known in Jamaica as “ virgin’s-bower” and “traveler’s joy.” The stems 
contain a coarse fiber and are used occasionally as a substitute for twine. 
The leaves of this and other species have an acrid flavor; crushed and ap- 
plied to the skin they are rubefacient and finally vesicant, and because of this 
property they are used in domestic medicine. The dried leaves lose their 
acrid properties. An ointment made with the leaves is used for cutaneous 
diseases. An infusion of the flowers and leaves is employed as a cosmetic, 
for removing freckles and other blemishes from the skin. The plant is said to 
be poisonous to cattle, and the root to have purgative properties. ° 

In spite of the variability exhibited, it seems impossible to divide the ample 
material at hand into groups characterized by any constant or important char- 
acter. Specimens referred by Hemsley to C. fammulastrum Griseb. belong here, 
as well as material referred to C. caripensis H. B. K. and C. sericea H. B. K. 

Clematis dioica or a closely related species is figured and described by Her- 
nandez* under the heading. ‘De Cocoztamatl, seu luteo tamatli, Urinaria 
mirabili.” His account, in part, is as follows: 

“ Cocoztamatl, which some ¢all Cocoztic, Cocoztin, or Cocoztli, is a climbing 
shrub, having a thick pale root, whence the name. The stems are smooth, slen- 
der, and round; the leaves sinuous and divided into three points. The flowers 
are white, of moderate size, very like those of Izquirochitl, and from them 
there spring berries, not unlike cherries, but white in color. The root is pale and

inodorous, its taste slimy, of moderate temper or slightly inclined to coldness 
and humidity. It is a wonderful diuretic, expels phlegm, and removes all 
urinary obstructions.” 

The name “ cocoztamatl” (‘“ yellow tomato,” of no application to the plant) 
is doubtless incorrect, and should be rather “ cocotemecatl” (‘‘ pungent-vine”’), 
as is indicated by Hernandez’s second account’ of the plant, which also is ae- 
companied by a figure. The description of the fruit, of course, is erroneous. The 
second account is headed ‘‘ De Cocotemeeatl, seu fune volubili acri,’ and is as 
follows: 

“ Cocotemecatl, which some call Cocotemecaxihuiil, is an herb with leaves like 
those of basil [Ocimum], but much larger, angled, and crenate. The stem is 
purplish and climbing; the flowers are small, borne on the ends of hairy branch- 
lets, and they change into purplish white pappus; the roots are fibrous. It grows 
at Yacapichtlan and Quauhquechollan, in hot and rocky places. The leaves, 
which are glutinous, if crushed and taken in the quantity of a handful, cure 
dysentery. The root and stems are hot and dry in the fourth degree; they are 
a remedy for ringworm and, if taken in a dose of two drachms, calm pains in 
the stomach and colic; they are diuretic, aid parturition, cure those affections 
which arise from cold, and allay pains caused by wind.”

Shrubs or small trees with yellow wood; leaves alternate, estipulate, pin- 
nate, the leaflets 3 to many, usually dentate, the teeth often spine-tipped; 
flowers yellow, perfect, racemose; fruit a berry, with few seeds. 

The wood is used in Mexico to give a yellow dye. The roots of O. aquifolium 
(Pursh) Rydb. (Berberis aquifolium Pursh), a species native of the western 
United States, but closely related to some of the Mexican ones, are official 
in the U. S. Pharmacopoeia. They are bitter and contain the alkaloids ber- 
berine, oxyacanthine, and berbamine. Both the fruit and roots have been 
recommended as possessing alterative, laxative, tonic, and diuretic properties. 
They are employed in syphilitic and scrofulous affections, chronic cutaneous 
diseases, convalescence from fevers, ete. This plant is known in the United 
States as Oregon grape; it is the state flower of Oregon.

*Carl August Ehrenberg (1801-1849) spent 10 years (1831-1840) in Mexico in 
Oaxaca, Puebla, Mexico, Hidalgo, San Luis Potosi, and other states. He was 
especially interested in Cactaceae, many species of which he introduced into 
cultivation in Europe. His collections consisted of about 2,000 numbers.

Chihuahua and Coahuila to San Luis Potosi. Western Texas (type lo- 
cality) and southern New Mexico. 

Shrub, 1 to 4.5 meters high; leaflets mostly 3 to 5 em. long, very thick and 
rigid, pale, especially beneath, with large spiny lobes or teeth; fruit red. 
“Agritos ” (Coahuila, Nuevo Leon, Texas); “agrillo” (San Luis Petosi, Seaf- 
ferd) ; “palo amarillo” (Chihuahua, Nuevo Leén, Durango). 

In Texas and New Mexico the name “agrito” is corrupted into “ agarita” 
or even “ algerita.” , 

The wood is sometimes used for tanning and for making ink. Like that of 
other species, it yields a yellow dye. The acid fruit is utilized for jelly, 
preserves, and tarts, and wine has been made from it. The roasted seeds are 
said to have been used as a coffee substitute. A decoction of the roct is 
reported to be employed in Texas as a remedy for toothache. The fiowers are 
said to supply bees with a good quality of honey. 

This is presumably the species to which Berlandier’* gives the name Chryso- 
dendron tinctoria, a new genus which, however, is not technically described. 
He states that the plant is known in Tamaulipas as “palo amarillo,’ and is 
used by the Indians to dye deerskins and cotton goods.

The roots are hard, tortuous, brown, and rugose, with a bitter flavor. They 
are said to have diuretic, emmenagogue, febrifuge, and expectorant properties, 
and are used in treating urinary and venereal diseases. The plant also has 
a great reputation throughout tropical America as a remedy for the bites of 
venomous snakes. It has been confused with the “pareira brava’ of com- 
merce, which is furnished by a South American plant (Chondodendron tomen- 
tosum Ruiz & Pavon) of the same family, and is used sometimes as an adul- 
terant of that drug. The leaves are said to be employed as a poultice for 
treating wounds. The name “ velvet-leaf” is applied to the plant in Jamaica. 
The leaves have been suspected to be poisonous to cattle.

A large tree, sometimes 30 meters high, with a trunk 1.2 to 1.5 meters in 
diameter; leaves persistent, oval or elliptic, 12 to 25 cm. long or larger, acute, 
lustrous, reticulate-veined ; flowers large, white, sweet-scented, the petals and

“ yoloxochitl ”” (Nahuatl); “hierba de las mataduras” (Morelos, Mexico, 
Ramirez) ; “laurel tulipin’” (Morelos) ; “ guielachi’” (Oaxaca, Zapetec, Reko). 

This is one of the best-known of Mexican trees. It was highly esteemed by 
the early inhabitants because of the sweet odor of the-blossoms, a single flower 
being sufficient to perfume a whole house. The tree was cultivated in gardens, 
and the flowers were reserved for the exclusive use of the nobility. The plant

was valued also for its reputed medicinal properties, and it still finds use in 


domestic medicine. The bark is employed for fevers, and is said also to have 
an effect upon the heart similar to that of digitalis. A decoction of the flowers 
is administered for epilepsy, paralysis, and various heart affections, and as a 
tonic. The plant, upon analysis, is said to yield a glucoside which dissolves the 
blood corpuscles.” 


The Nahuatl name, “ yoloxochitl,” signifies “ heart-flower,” an allusion to 
the shape of the unopened flower buds. Robelo gives “‘ chipagua” as one of the 
vernacular names—a derivative of the Nahuatl chipahuac, “the beautiful.” 
The species has been reported from Mexico’ as Magnolia glauca, a name synony- 
mous with M. virginiana L., which pertains to the sweet bay of the eastern and 
southern United States. It appears, also, that Talauma mexicana and Mag- 
nolia schiedeana have often been confused. The two species are much alike in 
leaf form and in the appearance of their flowers, but the fruits are very dif- 
ferent. 

Talauma macrocarpa is mentioned by Acosta (1590) under the name “ yolo- 
suchil.” It is illustrated and described by Hernandez * under the name “ yoloxo- 
ehitl.” The latter author discusses its medical properties, stating that “it is an 
excellent remedy for sterility,’ and remarks that the flowers were sometimes 
used to flavor chocolate.

by a storm in the southern ocean and Winter’s ship was driven to the Straits of a 
Magellan, where three weeks were spent with the object of improving the — 


health of the crew. Drimys was one of the plants which attracted Winter’s 


attention, and he used the bark for treating scurvy. Specimens of the bark © 


were presented to the famous botanist Clusius, who gave it the name of Cortex 
Winteranus. It became a favorite remedy in Europe, but as it was difficult to 


obtain the drug from South America the bark of Canella alba, a West Indian ~ 
tree, was often substituted for it. Winter’s bark is little used at the present — 


time except in domestic medicine in the regions where it is native. It is aro- 
matic and pungent and has tonic and antiscorbutic properties. In Brazil it is 
used for dysentery and for gastric disturbances. In Costa Rica the bark is 
chewed for toothache. The powdered bark is sometimes employed in Mexico 
as a condiment.

Veracruz and Oaxaca. Guatemala. 

Tree or large shrub with long narrow leaves; petals purplish within, greenish 
outside. “ Guineillo,” “ guineillo prieto”’ (Oaxaca) ; “‘ xochinacaztli”’ (Nahuatl). 

The aromatic petals were used in preconquest days for flavoring chocolate 
and are still so used in some localities. The flowers were used also as a remedy 
for asthma and other diseases.2. This plant was highly esteemed by the early 
inhabitants of Mexico, having been brought from the south to be grown in the 
gardens of the emperor. It is first mentioned by Sahagtin (1509), under the name 
“teunacaztli,’ “the sacred ear.” He states that the flowers were valued for 
their odor and for flavoring chocolate. Hernandez describes and figures* the 
plant in a chapter entitled “ De Yochinacaztli, seu flore auriculae.” The Nahuatl 
term xochinacazili signifies ‘‘ear-flower.”’ Hernandez states that the plant is a 
native of the tierra caliente, and that in the tiangues or markets of the Indians 
there is nothing more frequently found or more highly prized than this flower, 
“which is wont to give the greatest charm and taste, together witha very fragrant 


*Ludwig Hahn spent nearly 20 years in Mexico as a teacher of music, and 
made extensive collections of plants and animals, most of which were sent to 
Berlin. He was a member of the French Scientific Commission, and an associate 
of Bourgeau. He died in Mexico in 1873. Some of his plants are in the U. S. 
National Herbarum.

odor and flavor to that celebrated drink cacao, which they call chocolate, and it 
imparts to it certain tonic properties and wholesomeness as well. It is said that 
when drunk in water this flower dispels flatulency, causes phlegm to become 
thin, warms and comforts the stomach which has been chilled or weakened, as 
well as the heart; and that it is efficacious in asthma, ground to a powder with 
addition of two pods of the red peppers called texochilli, with their seeds re- 
moved and toasted on a conmal, which is a kind of griddle on which the natives 
toast and make their bread called by us tortillas, adding to the same three drops 
of balsam and taking it in some suitable liquor.” It is of interest to note that 
the dried flowers are still offered for sale in the markets of Guatemala.

The tree often grows about salt water, associated with mangroves. Its 
English names are “ pond-apple,” “ alligator-apple,” and “ monkey-apple.” The 
fruit is insipid but is said to be eaten in some localities, while in others it is 
regarded as poisonous. It is said to be eaten by the alligators that frequent 
the banks where it grows, hence the name “alligator-apple.” The very light 
wood is used to make bottle corks and floats for fish nets. 


4. Annona muricata L. Sp. Pl. 536. 1753.

The fruit of the soursop is highly esteemed in tropical regions. It is 
eaten fresh, used in preparing beverages, made into jelly, tarts, or preserves, 
and sometimes fermented to obtain an intoxicating drink. Stock also are fond 
of the fruit. It is reputed to have pectoral, antiscorbutic, and febrifuge prop- 
erties. The seeds and green fruit are astringent and are employed as a 
remedy for dysentery. The leaves, too, are used medicinally, also the flowers. 
One of the earliest writers to describe the plant is Oviedo (Lib. VIII, Cap. 
XVII), who used the Haitian name “ guanabano.”

Widely cultivated in Mexico, and in tropical America generally. Native of 
the Andes of Peru, but naturalized in Mexico at a very early date. 

Tree, 4.5 to 7.5 meters high; leaves mostly oval or rounded-oval, obtuse, 
pubescent; petals greenish yellow or rufous outside, pale yellow or whitish 
within; fruit globose or ovoid, the surface with rounded protuberances or 
marked with U-shaped areoles, sometimes smooth, the pulp white, pleasantly 
acidulous. ‘ Chirimoyo” or “ chirimoya” (Jalisco, Oaxaca, etc., Colombia, 
Peru; the name of Peruvian origin, said to signify “ cold-seed”); “ pox,” 
“tzuli pox”? (Yucatan, Maya) ; “ quauhtzapotl,” “ matzapotl”’ (Nahuatl). 

One of the most highly valued species because of its excellent fruit; much 
cultivated in the tierra caliente, in several forms of variable quality. The fruit 
is sometimes fermented to obtain an alcoholic beverage. Macfadyen states that 
in Jamaica the dried flowers were used to flavor snuff. The seeds are used in 
Mexico as an emetic-cathartic and as an insecticide. In the first case one or 
two seeds are swallowed; they are first roasted slightly, their shell removed, 
and the embryo crushed in water or milk. For the destruction of parasites 
upon the human body, the seeds are crushed, mixed with lard, and applied as 
an ointment to the parts affected. Cortina, who analyzed the seeds,’ states that 
they contain sugar, gum, albumen, extractive matter, oil, and resin, the last 
probably being the emetic-cathartic agent.

times of the year. It is eaten alone or made into sherbets and is not cooked 
like that of some other species. The leaves are sometimes rubbed over floors 
or placed in hens’ nests to keep away vermin. The seeds likewise have in-

secticide properties. The crushed leaves are sometimes applied as poultices 
to ulcers and malignant sores. The root is a drastic purgative. 

The tree is described by Oviedo (Lib. VIII, Cap. XVIII) under the name 
“hanon.” Hernindez describes and figures* it as “ahate de Panucho (P4- 
nuco)”; he also illustrates it,? without description, as ‘ate vel ahate de Pan- 
nuco.” The English names applied to this species are “sugar-apple” and 
“ sweetsop.”’

the tropics. 

Tree, 4.5 to 7.5 meters high; leaves deciduous, lanceolate or oblong, acute, 
nearly glabrous; petals olive or yellowish, usually stained with purple within 
and with a dark purple spot at base; fruit 7.5 to 12.5 cm. in diameter, the 
surface divided into angled areoles, uSually reddish or reddish brown, the 


pulp sweetish, insipid, tallow-like. “ Quauhtzapotl” (Nahuatl); “anona” 
(Oaxaca, ete., Nicaragua, Philippines, Guam); ‘anona colorada” (Chiapas,

The wood is light and soft. The bark is said to have astringent and tonic 
properties, and that of young branches to give a useful fiber. The leaves and 
branches are used for tanning and are said to give a blue or black dye. The 
English names are “ custard-apple” and “ bullock’s-heart.”

Myristica mexicana is considered synonymous with Compsoneura sprucei by 
Warburg, the monographer of the group, but it seems probable that further study 
will show that the Mexican plant is a distinct species. The type of M. mexicana 
is from the banks of the Rio Puyapatengo.

REFERENCE; Mez, Jahrb. Bot. Gart. Mus. Berlin 5. 1869. 

Aromatic evergreen trees or shrubs; leaves alternate, persistent, glandular- 
punctate, estipulate, entire; flowers perfect or unisexual, small, green or yellow, 
usually cymose, umbellate, or capitate; perianth limb usually 6-lobed; corolla 
none; stamens and staminodia normally twice as many as the segments and 
opposite them, arranged in 2 or 4 series; anthers erect, 2 or 4-celled; fruit 
baccate or drupaceous, 1-seeded. 

In this family flowers are usually necessary for determination, and fruiting 
specimens are of little value unless accompanied by flowers. 

The common European laurel, Laurus nobilis L. (“laurel”) is cultivated in 
Mexico as a shade tree. The writer has seen no material of Acrodiclidium 
mexicanum and A. misantlae recently described from Veracruz by Brandegee.* 
The genus is not otherwise known from Mexico, and it is probable that both 
these species belong to genera listed below. 

The only Mexican representative of the family not listed here is Cassytha 
filiformis L., a yellowish leafless twining parasitic plant, in general appearance 
much like dodder (Cuscuta spp.). 

Two well-known Old World trees of the family are Cinnamomum camphora 
(L.) Nees & Eberm., camphor (“alcéinfor”), and C. zeylanicwm Nees, cinna-

This species is cultivated in Veracruz and is probably also indigenous there. 
The flowers are pale greenish yellow, turning crimson at the base in age, or 
sometimes light rose. The stamens also turn crimson with age, and the glands 
are bright orange. The flowers of P. americana are said to be pale green, not 
changing color with age. 

The fruit is much like that of the common avocado, and equally variable in 
form and quality. The skin is thick but leathery and pliable; the flesh brown- 
ish white, of fine oily texture. The flavor is similar to that of the common 
avocado but distinguishable, suggesting that of a ripe coconut. The cotyledons 
when cut are rose-pink ; in P. americana they are whitish.

Commonly cultivated in Mexico, and probably native in the southern part. 
Widely cultivated in tropical regions. 

Tree, sometimes 20 meters high, with a trunk 60 cm. in diameter, the bark 
rather thin, light gray, fissured; leaves oval to elliptic, 10 to 30 cm. long, 3.5 
to 20 em. wide, acute or obtuse, copiously pubescent when young; flowers green- 
ish; perianth 5.5 to 7 mm. long; fruit oval or pear-shaped, sometimes 18 cm. 
long, smooth, with thick oily pulp and a very large seed; wood rather soft, 
fine-grained, reddish brown or light brown, its specific gravity about 0.65. 

The fruit is known in Mexico as “aguacate” or “ahuacate,’ from the 
Nahuatl “ ahuacatl’’? or “ ahuacuahuitl.” The following additional names are 
used, some of them referring to horticultural varieties: ““Aguacate oloroso” 
(Veracruz, Oaxaca); “on” (Yucatan, Maya); “aguacate xinene,” “ xinene” 
(Oaxaca, Reko); “tonalahuate” (Morelos, Veracruz, Ramirez); “ cupanda” 
(Tarascan) ; “aguacatillo”’ (Michoacan, Jalisco) ; “ pahuatl” (the name of a 
large variety, according to Starr’); “pagua” (a large variety, Robelo) ; 
“koidium,” “ koitum,” ‘ kuitm” (Mixe, the fruit, Belmar; the tree is “ kuitm- 
keip”’); “ttatzin” (Otomi, Buelna); “palta’’ (Colombia, Ecuador, Peru; 
the Quechua name; Ramirez reports it as in use in Mexico, but this is doubt- 
ful) ; “cura” (Colombia). The best English name is ‘ avocado,” a derivative 
of “aguacate’” This word has been variously modified, the extremes being 
perhaps “ abogado,” the Spanish word for “ lawyer,’ and “ watercats,’’ employed 
by some English writers. The name “alligator-pear” is sometimes applied, 
but this is an objectionable name. In the various Maya dialects of Central 
America the names employed are “0,” ‘oj,’ “ju,” “un,” “um,” and “on.” 

The avocado is one of the best-known of Mexican trees, haying been cultivated 
for many centuries. It has been introduced into most tropical regions of the 
world, and in recent years into southern Florida and California. It is of inter- 
est to note that the Trapp avocado, the form most commonly grown in Florida, 
belongs to a distinct species, of unknown origin, distinguished by having the 
perianth glabrous within. It has been described recently by Blake* as Persea 
leiogyna. 

Two principal horticultural forms of Persea americana are recognized, the 
“West Indian type,” with smooth fruit and leathery skin, and the “ Guatemalan 
type,” with rough or warty fruit and brittle skin. There is great variation in the 
size and shape of the fruit. 

In tropical America the trees are grown from seeds, beginning to bear when 
four or five years old and continuing their production sometimes for 50 years or 
more. In modern practice the best forms are propagated by budding. <A good- 
sized tree will produce as many as 500 fruits per year. The fruit has a pleasant 
flavor, and is usually eaten as a salad, with the addition of salt, pepper, vinegar, 


*This is also the Nahuatl term for testicle. It is uncertain which is the 
primitive meaning.

and other condiments, but sometimes it is prepared with sugar or wine. It is 
eaten by all kinds of domestic animals. 

A large number of therapeutic uses are reported for the plant. The pulp is 
eredited with hastening the suppuration of wounds and is reputed to have 
aphrodisiac and emmenagogue properties. The rind is used to expel intestinal 
parasites. The seeds contain a milky juice which turns red on exposure, and 
which produces an indelible stain on linen. Ground and mixed with cheese, 
meal, etc., the seeds are used to poison rats and mice. An ointment of the pul- 
verized seeds is sometimes employed as a rubefacient, and a decoction of them, 
or a piece of a seed placed in the cavity of a tooth, is believed to cure toothache. 
The leaves and bark are employed in domestic medicine because of the pectoral, 
stomachic, emmenagogue, resolutive, and antiperiodic properties ascribed to 
them. The seeds are used also for the manufacture of various trinkets. 

The avocado is noted by all the early writers upon tropical American plants. 
Oviedo (Lib. IX, Cap. XXIII) gives a very full account of the tree and of 
the fruit, which he describes as superior to the pears of Castile. Acosta gives 
a brief account of the fruit, under the name “palta.” Sahagtn writes the 
name “ auacatl,” and states that there are also other kinds besides the common 
one: The “ tlacaclauacatl,’ which women nursing dare not eat, because the 
fruit causes diarrhoea in the children nursed; and the ‘“quilauacatl,” or 
“sreen aguacate,” a form with green skin, ‘and very good to eat.” He states 
that the powdered seeds were employed as a remedy for dandruff. Hernandez 
also gives a long account’ of the avocado, in a chapter entitled “De Ahuaca 
Quauhitl, seu Arbore Querciformi butiraceo fructu.” He describes the leaves 
as fragrant, and consequently doubtless refers to the Mexican type, Persea 
americana drymifolia. He states that by pressure oil was obtained from the 
seeds and used to cure eruptions of the skin.

Nectandra rodiaei Hook., of northern South America, is the greenheart, whose 
wood is valuable, especially because of its great durability in water. The bark 
contains the alkaloids bebeerine, sipirine, and nectrandrine. It is tonic, some- 
what astringent, and febrifuge, somewhat resembling cinchona in properties al- 
though greatly inferior in quality. It has been used in the treatment of inter- 
mittent and remittent fevers. The Indians of British Guiana are said to make a

Tree, 4 to 8 meters high, the trunk sometimes 60 cm. in diameter, covered 
with corky bark; leaves clustered at the ends of the branches, 10 to 45 em. 
long or larger, with few or numerous narrow lobes, glabrous above, beneath 
pale and tomentose or glabrous. ‘“ Chicalote,” ‘‘chicalote de arbol” (Tepic) ;

“ ahuacachilli”’ (Morelos) ; “ palo del diablo” (Durango, Sinaloa) ; “ palmilla ” 
(Sinaloa). 


The bark yields a yellow dye which was used by the early inhabitants of 
Mexico for coloring plumes and other objects. The plant contains several alka- 
loids similar to those obtained from the poppy plant (Papaver somniferum 
L.). These, when injected beneath the skin, cause local anesthesia, and for 
this purpose they have been used by surgeons in the City of Mexico, while 
performing operations. The wood is useless for timber or fuel, but is some- 
times employed in tanning. 

The species is illustrated by Hernindez,* and described in a chapter headed 
“De Enguamba.” He states that the plant grows about Uruapam, and that 
an oil extracted from the fruit is employed for dissolving tumors and cleans- 
ing ulcers. On page 158 of the Thesaurus Hernandez figures and describes an- 
other plant under the heading “‘ De Cocoxihuitl, seu herba acri.” The figure 
may represent either Bocconia arborea or B. frutescens. WHernandez’s de- 
seription is based upon a plant in the gardens of the King of Texcoco, where. 
he says, he “studied the plant for some days.” He gives the meaning of the 
Nahuatl name as “ hot-herb,” but it may be that it should be translated rather 
“ yellow-herb,” an allusion to the color of the juice. He gives the following 
account of the names and medicinal properties of the plant: “The plant is 
hot and dry in the fourth degree, and possesses a certain astringency. The 
shoots, deprived of the bark, dissipate films and ulcers of the eyes. The 
juice relieves wind on the stomach, cures eruptions (as does the fruit also), 
and alleviates pains of cold origin. The leaves, crushed and applied as a poul- 
tice, heal old wounds and dissolve warts. Some call this tree Quauh chilli, 
because of its acrid and burning flavor, like that of the peppers called Chilli 
by the Mexicans. It grows in temperate or hot regions, as well as in gar- 
dens. Some call it also Totolinyzochtl, or pigeon-flower, and some Tlacoxihuitl, 
{rod-herb].”

“mata-chande,” “sarcillejo” (Colombia); “sangre de toro” (Guatemala) ; 
“sancho amargo” (Argentina, Uruguay) ; “ yagrumo macho” (Santo Domingo). 
Probably some of the other names listed for B. arborea are applied also to this 
species. 

The plant contains an alkaloid, protopine. The yellow or orange juice is very 
bitter and acrid and has a disagreeable odor. It is used for treating ulcers, skin 
eruptions, chilblains, bronchitis, and chronic ophthalmia, and to remove warts, 
and is said to have vermifuge and purgative properties. The leaves, too, are 
sometimes heated and applied as a poultice to wounds. In Colombia an infusion 
of the roots is valued as a remedy for jaundice and dropsy. In Jamaica, it is 
stated, the leaves are rubbed on house floors to keep away insects, and in Co- 
lombia the oil extracted from the seeds is used to destroy vermin on the head 
and skin. 

Robelo gives as vernacular names in Mexico “ cocojegiiite”” (from cococxi- 
huitl), “ clacojegiiite’”’ (from tlacoxihwitl), and “ guachichile” or “ guachichil ” 
(from cuau-chilli, “ tree-chile’’). He states that the plants were used in pre- 
conquest days to adorn the temples.

1. Atamisquea emarginata Miers, Trav. Chile 2: 529, 1826. 

Dry plains and hillsides, Baja California and Sonora. Argentina. 

Densely branched shrub, 1 to 6 meters high, ill-scented, with brittle branches ; 
leaves linear or oblong-linear, 1 to 3.5 em. long, short-petiolate, emarginate at 
the apex, green on the upper surface, scaly beneath; flowers small, solitary or 
fasciculate, sweet-scented; sepals and petals each 4; fertile stamens 6; fruit 
oval or subglobose, about 8 mm. long. 


5. CRATAEVA L. Sp. Pl. 444. 1753. 


Shrubs or trees; leaves deciduous, very long-petiolate, the leaflets 3; flowers 
racemose or corymbose, the stamens long-exserted; petals 4; stamens 8 to 20; 
fruit baccate, large, long-stipitate.

Tamaulipas to Sinaloa and southward nearly throughout the lower parts of 
Mexico. West Indies, Central America, and South America, 

Glabrous tree, usually 6 to 9 meters high, but sometimes as much as 18 
meters; bark grayish brown; leaflets ovate, elliptic, or oval, 5.5 to 15 ecm. 
long, thin, acute or acuminate, paler beneath; flowers green or purplish; fruit 
subglobose, 2.5 to 5.5 cm. in diameter. ‘“ Zapotillo amarillo’ (Colima) ; ‘‘ Tres 


Marias” (Yucatén); ‘“xkolocmax” (Yucatén, Maya); “cascarén” (Ta- 
basco); ‘palo de guaco” (Panama); ‘‘manzana de playa” (Nicaragua) ; 
“zorrocloco” or ‘ sorrocloco” (Colombia); “toco” (Trinidad, Venezuela). 


The bark has a disagreeable odor; it is reputed to have tonic, stomachic, anti- 
dysenteric, and febrifuge properties. The roots are very acrid, and their juice 
applied to the skin~- produces blisters. The leaves are sometimes used as 
poultices. 

It may be that C. gynandra L. (if that species is distinct from C. tapia) also 
occurs in Mexico, but the specimens seen afford no convincing evidence to that 
effect.

The usual English name is “ horseradish tree.” The roots have the odor and 
flavor of horseradish (Armoracia rusticana Gaertn. Mey. & Schreb.), for which 


they are sometimes substituted; a decoction of them is used in Nicaragua for 


dropsy, and their juice is applied as a rubefacient or counter-irritant. The 
wood is said to yield a blue dye. The leaves and young branches are relished by 
stock and are sometimes cut for fodder. In India the young leaves, pods, and 


_ flowers are cooked and eaten. The leaves are sometimes applied as a poultice 
_ to sores, and they are said to have purgative properties. The seeds yield the 


| 


“ben ” oil of commerce, which is used for lubricating watches and other delicate 
machinery. The oil is odorless and never becomes rancid, consequently it is 
useful in the manufacture of perfumes. It is very acrid and has purgative prop- 
erties, but its use is somewhat dangerous if taken internally. It is sometimes 
applied externally for cutaneous diseases.

Shrubs; leaves deciduous or somewhat persistent, entire or shallowly serrate;

Patoni gives the local name of one of the Durango species as “ mirto.” 
Many of the species which are natives of Asia and the United States are culti- 
vated for their showy, often fragrant flowers. The native species, and perhaps 
soime of the foreign ones, are grown in Mexican gardens. The usual English 
names for the plants are “ syringa’’* and “ mock orange,” the latter name prob- 
ably given because of the sweet odor of the flowers in some species. Phila- 
delphus coronarius L., an Old World species, has been reported from Mexican 
gardens, and may very. likely be cultivated there. The name was applied by 
Sessé and Mocifio? to a native species.

This species has been introduced into cultivation in Europe. It or one of the 
related species is figured and described by Hernandez? in a chapter entitled “ De 
Acuilotl, seu Volubili Aquatica.” His account is as follows: ‘‘Acuilotl, or 
water-vine, is so called by the Mexicans not without reason, for it grows in moist 
places, and spreads over the ground or climbs over near-by trees. There are two 
sorts, differing only in color of flowers, name, and size of leaves. The first has — 
pure white flowers and slightly smaller leaves, and is called Acwilotl; in the 
second the flowers are pale and the leaves larger, and it is called Cozticacuilotl,

because of the yellow color of the flowers. The stems of both are round, 
purplish, woody, brittle, and slender, with soft pith. In form and odor the 
flowers are not unlike the musk rose, a plant not wholly different from this one. 
The leaves are like those of the bramble, but less toothed, with nerves running 
lengthwise, and with almost the odor of cucumber. The flowering branches are 
employed for their perfume by the Indians, and for the garlands which they use 
so much; and a scented water of pleasant odor is distilled from them. The 
plant grows in temperate or rather cold places. The leaves are bitter and dry 
and hot in almost the third order, wherefore, if taken in wine in the quantity 
of a handful, they relieve colic, and if crushed and applied as a plaster, they ease 
strained members, and dissolve tumors beyond belief.” Hernindez also gives an 
illustration,’ without description, of the “ cozticacuilotl xochitl.”

* August Fendler (1813-1883), a native of Prussia, came to the United States 
in 1834. Later he visited Prussia, but soon returned to North America and set- 
tled in St. Louis, where he made the acquaintance of'Engelmann, In 1847 he 
followed the Santa Fe Trail to New Mexico, where he made a large collection of 
plants, upon which a report was published by Gray. Later he botanized in 
Panama and Venezuela, where he obtained important collections, and finally 
settled in Trinidad, where he died.

The wood of the sweet-gum takes a good polish but warps badly. It is used in 
the United States for furniture, shingles, paving blocks, etc., and in Mexico for 
boxes, chests, and other articles. For interior finish of houses it is very popular, 
for it is of fine appearance when polished. The leaves (which are beautifully 
colored in autumn, before falling) contain tannin. 

The resin or balsam obtained from the tree appears to be little known in the 
United States, but in Mexico and Central America it has been much used from 


the earliest times. It has been employed also in Europe in medicine, under the 


Dames “liquidambar” and ‘‘copalm balsam.” The balsam is a transparent 
yellowish liquid with peculiar agreeable balsamic odor and bitter warm acrid 
taste; upon exposure to the air it hardens. The gum is sometimes chewed in the 
southern United States to sweeten the breath. A sirup prepared from the bark 
has been used as a remedy for diarrhoea and dysentery, especially in children. 

The method of gathering the balsam in Honduras, and the uses made of 
it there, are detailed in the following account by W. V. Wells: “The owners 


*Pxplorations and adventures in Honduras, pp. 321-322. 1857.

of cattle estates send their mayordomos into the woods to collect the gum, 
which is found exuding from the pores of the tree, and often collecting, like 
that of the peach, in some knot or bruise along its smooth surface. The gum 
trickles from the incision in transparent tears down the conduits made by 
the natives, until, from a spout inserted in some convenient place, a pint or 
more is collected. By climbing to the lower branches a purer quality is said 
to be obtained. 

“A rim of plantain leaves, bound tightly around the trunk and left for 
several days, is found filled with the precious distillation. I afterwards 
went with Julio, the mayordomo of Lepaguare, about two leagues to one of 
these trees, where he procured from the leafy troughs at least a pint. The 
trunk of the liquid amber-tree is clammy to the touch, so that numerous living 
bees, attracted by the sweet, glutinous substance sweating from the pores, are 
found sticking helplessly to the bark. The gum, when bottled, becomes of the 
consistency of sirup. In the caballeria of Don Francisco Zelaya there were 
at least two gallons used for no other purpose than to heal the wounds of 
horses, mules and cattle. * * * I was assured that it never failed to 
effect a speedy cure for flesh-wounds in horses, and that in the mountains, 
when the mahogany-cutters or hunters wounded themselves, they applied at 
once to this tree for remedios. It is sometimes mixed into a stiff gum with 
other substances, and chewed by the Indians as a preservative of the teeth.” 

One of the earliest references to the sweet-gum tree is that by Bernal Diaz 
del Castillo* who, describing the meals taken by the Mexican emperor, says: 
“After he had dined, they presented to him three little canes highly orna- 
mented, containing liquid amber, mixed with an herb they call tobacco, and 
when he had sufficiently viewed and heard the singers, dancers, and buffGons, 
he took a little of the smoke of one of these canes.” The balsam and gum were 
much used for flavoring tobacco and also as incense in houses and temples. 
As for medicinal uses, the tree was employed in catarrhal, stomachic, and other 
affections, and was reputed to have stimulant properties. The following ac- 
count of the tree by Hernindez,’? accompanied by a figure, is given in a chapter 
entitled ‘‘ De Xochiocotzo Quahuitl, seu Arbore Liquidambari Indici”: ‘ Xo- 
chiocotzo Quahuitl is a large tree, with leaves almost like those of a maple, 
divided into three points and two notches, toothed, on one side whitish and 
on the other darker. The bark of the trunk is partly yellow and partly 
green. It grows in plains and in hot, or sometimes in temperate places, like 
Hoeyacocotla, Quahuchinac, and Xicotepec. Its nature is hot and dry, and 
its odor pleasant. If the bark of this tree is cut, there flows from it what is 
called Indian Liquidambar by the Spaniards, and by the Mexicans Xochiocotzol, 
in the sweetness of its odor very like Styrax. Its nature is hot in the third 
order, and dry, and added to tobacco it strengthens the head, belly, and heart, 
induces sleep, and alleviates pains in the head that are caused by colds. 
Alone, it dissipates humors, relieves pains, and cures eruptions of the skin. 
From the same tree, either spontaneously or from incisions, there is dis- 
tilled an oil, no whit inferior to the famed liquor, either in sweetness of odor 
or in medicinal virtues, albeit some assert that the oil is distilled from the 


first liquor, put in a suitable place, or expressed, so that the thinner part of —

It relieves wind in the stomach and dissipates tumors beyond belief, it aids 
digestion, strengthens the belly, heals uterine affections, and others similar to 
those, either alone or mixed with other drugs. There are some who prepare 
a kind of balsam from the twigs steeped in water, but this is meaner and less 
suitable for the aforesaid remedies, and not fit for any except the meaner 
uses.”

The species of this genus are known by the English names of “ buttonwood,” 
“sycamore,” and “ plane-tree.” They are excellent shade trees and especially 
to be recommended for street planting. They are little attacked by insects 
and usually have broad crowns, with tough branches not easily broken by the 
wind. The native species are planted as shade trees in Mexico.

“nalo verde” (Durango, Patoni). 

The wood or bark is said to be used for dyeing goat skins yellow. Patoni 
states that the name “ guayule” belongs properly to this plant rather than to 
Parthenium argentatum, to which it is now generally applied, and that it is 
doubtful how it came to be applied to the latter plant. V. angustifolia differs 
from the typical form in having less salient teeth, but the two forms are con- 
nected by specimens intermediate in character.

leaves 5 to 12 mm. long, gland-dotted; flowers sometimes pinkish. ‘ Palo 
amarillo” (Baja California); ‘‘hierba del pasmo,”’ “ chamiso” (California). 

Often known in California as “ greasewood.” A decoction of the plant is used 
locally for chills and fevers and as a tonic. The Coahuilla Indians of Cali- 
fornia employed the wood for arrow points and rabbit sticks; a decoction of 
the twigs as a purgative and vomitive in the case of pains in the stomach and 
intestines; the powdered twigs mixed with grease as a salve; and a decoction 
of the plant as a remedy for sick cattle.

A very handsome shrub when in either flower or fruit; of Some value as a 
forage plant. It is sometimes known in the southwestern United States as 
“Apache-plume.” The Tewa Indians of New Mexico employed the smaller 
branches, tied in bundles, as brooms, and the larger ones for arrow shafts. 
They also, like the Hopi of Arizona, employed an infusion of the leaves for 
washing the hair to promote its growth, probably, according to Hough, because 
of the hairy fruit.

obtained material for clothing from this shrub. The thin, silky inner bark was 
removed in strips and woven or braided together. The bark was used also 
for sandals, ropes, and mats. The Gosiute Indians are said to have used the 
plant medicinally, but in what manner is not stated.

Patoni gives the vernacular name of a Durango species as “lentisco.’”’ Be- 
eause of their very hard, tough wood the plants are commonly known in the 
United States by the name of “ mountain mahogany.” The wood of C. ledi-

11. RUBUS L. Sp. Pl. 492. 1753. 


Erect, prostrate, or scandent shrubs, usually armed with prickles or bristles; 
leaves persistent or deciduous, petiolate, simple or palmately or pinnately 
compound; ffowers usually racemose or paniculate, large and showy; fruit 
of numerous small juicy drupes, these united and falling off like a cap or 
sometimes united to the receptacle, rarely falling off separately. 

The genus contains the cultivated blackberries (“ zarzamoras”), dewberries, 
and raspberries (‘‘ frambuesas”), some of which are grown in Mexico, although 
not very extensively. The native species are known in Mexico as “ zarzamora ”; 
the Tarascan name is said to be “ situni”’; the name “ coatlamitl ”* is reported 
from the Valley of Mexico. The.fruit of all the native species is edible, and 
is used extensively in Mexico. > 

The root bark of the wild blackberries is official in the U. S. Pharmacopoeia. 
The decoction has long been a favorite domestic astringent remedy for di- 
arrhoea. 


*The name should probably be “coatlantli” (‘‘serpent’s tooth”). The 
Nahuatl name for the fruit is “ coatlanxocotl.”

both United States species, R. frwticosus, a Huropean species, and I. pentha-

The tropical American species of Rubus seem to have attracted little atten- 
tion from the early writers, but they are mentioned by Oviedo (Lib. VIII, 
Cap. XXVI), who says of the “zarzamoras:” “Although these can not be 
eounted as trees in Spain, they are so here, where they have thicker trunks 
and stems and are much taller than in Castile, and for their size must be 
termed trees.” 

Leaves simple. Plants unarmed.

Erect shrubs, armed with prickles; leaves pinnate; flowers solitary or 
corymbose, large and showy; hypanthium enlarged and fleshy in fruit, bearing 
numerous achenes on the inner surface. 

Many species of roses (‘‘rosas’’) of European or Asiatic origin are cultivated 
in Mexico for their beautiful flowers. The fruits of some of the North 
American species are sweet and palatable when frosted, and they were eaten 
by the Indians, especially in winter, when food was scarce. Among the Tewa 
Indians of New Mexico a salve made from the petals is used for sore mouth, 
and a decoction of the fruit was employed by the Omaha as a wash for sore 
eyes. Some of the tribes smoked the inner bark, either alone or mixed with 
tobacco.

Trees or shrubs, sometimes armed with spines; leaves alternate, stipulate, 
dentate or lobate; flowers perfect, solitary, racemose, corymbose, or cymose, 
often large and showy; petals 5; stamens usually numerous; fruit a pome, this 
consisting of the much enlarged, fleshy calyx tube, inclosing the papery or 
leathery seedlike carpels. 

Several important cultivated fruit trees belong to this family, chief of which 
are the following: The apple, Malus sylvestris Mill. (“‘manzano,” the tree, 
“manzana,” the fruit; ‘“ belehui,” Oaxaca, Zapotec, Reko; “ tnutinumi,” Oaxaca,

REFERENCE: Eggleston, Bull. Torrey Club 36: 501-514. 1909. 

Shrubs or small trees with dark brown, scaly bark, nearly always armed 
with long stout spines; leaves dentate or lobate, petiolate, deciduous; flowers 
white, corymbose, strong-scented, the odor often very disagreeable; fruit 
usually globose or pyriform; wood hard and tough. 

The species (in the United States called “hawthorn” and ‘red haw’’) are 
known in Mexico under the name ‘“ tejocote” or “texocotl.” Buelna gives 
the Otomi names as “ dopri,” “ dopini,” and “vipeni.” The fruit is highly 
valued and is a common article in the markets. It is eaten raw or more com- 


_ monly made into jelly or preserves. The trees are often cultivated. The fruit 


is reputed to have pectoral properties, although, apparently without sufficient 
basis. The roots are used in domestic medicine because of their supposed 
diuretic and antidysenteric properties. The wood, which is hard and compact, 
is used for various purposes.

The fruit is edible. The stems, according to Herrera, are made into canes, 
known as ‘“ yaritas de Apizaco,” which are notable for their flexibility. In the 
typical form of the species the calyx is tomentose outside, but in most of the 
specimens the calyx is glabrous. The northern (glabrous) form may be a dis- 
tinct species, but there seem to be some intermediate specimens. Crataegus 
inernuis Sessé & Moc.' is perhaps another synonym of this species.

Trees or shrubs; leaves serrate or entire, the teeth often gland-tipped ; flowers 
solitary, corymbose, umbellate, or racemose; fruit glabrous or pubescent. 

Several important fruit trees of this genus are cultivated in Mexico, chief of 
which are the following: The peach, Prunus persica (L.) Sieb. & Zuec., 
“durazno,” “melocot6én,” “ prisco,”’ “albérchigo,” ‘“ pahsh’” (Mixe, Belmar), 
“ Gheanza,” “ixi” (Otomi, Buelna) ; the apricot, P. armeniaca L., “ chabacano,” 
“ albaricoque,” “-damasco”’; the almond, P. communis (L.) Fritsch, “ almen- 
dro” (the tree), “almendra” (the fruit); various plums, P. domestica L.. 
P. insititia L., ete., ‘“ ciruelo,” “ ciruelo de Espana”; and cherries, P. cerasus 
L., ‘“cerezo,”’ (the tree), ‘“ cereza” (the fruit), “guindo.” All these were 
doubtless introduced into Mexico by the Spaniards at an early date. It is of 
interest to note that peaches were probably introduced into the United States 
directly from Mexico. Havard remarks* upon the subject as follows: 

“The Indians certainly exhibited commendable promptness and industry, 
after the advent of the whites, in introducing such fruits as were shown to be 
desirable. Thus the Peach brought to Mexico soon after the conquest was, 
according to the testimony of Du Pratz, found in general cultivation among 
the Indians of Louisiana when the French settled that province in 1698, and 
had become abundant in Georgia at the time of the settlement of the English 
in 1732. Wm. Bartram describes the carefully planted Orange groves of the 
Indians which he noticed in 1773. The early introduction and propagation 
of these two plants by the Indians led to the erroneous impression that they 
were of American origin.”

This species has often been confused with P. americana Marsh. and P. nigra 
Ait., both natives of the United States. Those two species are the source of 
many of the cultivated plums. In the wild state the fruit is of fair quality, but 
it is greatly improved by cultivation. There is reason to believe that these 
wild plums were cultivated by the Indians, although, as Havard remarks, the 
Indian orchards were perhaps only the result of seeds accidentally dropped 
about villages and camping grounds.

Shrub or usually a tree, sometimes 15 meters high, with a trunk nearly a 
meter in diameter, the bark reddish brown or grayish, nearly smooth, the 
crown broad; leaves lanceolate to ovate, lustrous, nearly glabrous; fiowers 
small, white; fruit red or black, 1 cm. in diameter or smaller. Generally 
known as “capulin,” “ capulf,’ or “ capollin” (the name doubtless applied to 
other species also, and applied to this species in Peru and Ecuador) ; “ tnun-

daya” (Oaxaca, Mixtec, Reko); “xeugua” (Michoacin, Leén); “cerezo” 
(Guatemala); “pa kshmuk” (Mixe, Belmar); “detze,’ “ghohto” (Otomi 
Buelna). 

- The wood is of good quality and is much used for general carpentry and 
cabinet work. The large juicy fruit is highly esteemed, and for this reason 
the trees are sometimes planted about houses. In early times, at least, an 
intoxicating drink was made from the fruit. The juice or the fruits are 
sometimes mixed with cornmeal to make a kind of cake known as “ capulta- 
mal” or “capoltamalli.” The bark, leaves, or seeds, when crushed in con- 
tact with water, develop hydrocyanic acid, and under proper conditions they 
may poison animals which eat them; the same is true of other members of 
the genus. The distilled water of the leaves is substituted in Mexico for 
cherry laurel water, and has the same antispasmodic properties. A decoc- 
tion of the bark is employed for dysentery and is reputed also. without suf- 
ficient basis apparently, to have febrifuge properties, The bark of Prunus sero- 
tina Ehrh. of the United States, a closely similar species, is official in the 
U. S. Pharmacopoeia. It has tonic properties and the power of calming 
irritation and diminishing nervous excitability. It has been employed exten: 
sively for the hectic fever which accompanies scrofula and tuberculosis. The 
fruit of the same species has been much used for flavoring spirituous liquors 
and various nonintoxicating beverages. 

The fruit of Prunus capuli is mentioned by the earliest Spanish visitors to 
Mexico. Bernal Diaz del Castillo, in relating the hardships of the siege of 
Mexico in 1521, when the Spaniards and their allies were often in the direst 
straits for want of food, says, “Corn we had sufficiency of, but we wanted 
refreshments for the wounded. What preserved us was the plant called 
quilites, cherries while in season, and tunas or Indian figs.” Sahagfin treats 
of the tree under the name “capulin.” The juice of the leaves and young 
shoots, he states, was dropped into the eyes to heal inflammation, and the 
kernels of the seeds were roasted and eaten. Hernandez also treats of the 
plant in a chapter,’ accompanied by a figure, entitled ‘De Capolin, seu 
Ceraso dulci indica.” ‘‘ The fruits,’ he says, ‘are slightly acid and astringent, 
although when fully-ripe they are sweet and lose a great part of their harsh- 
ness; and by some persons they are considered in no wise inferior to our 
cherries. In nature they are hot, dry, and somewhat astringent. They are 
made into bread and wine in times of scarcity. They furnish a sad food, and 
one which is hurtful in a way to the heart; and they impart a black color 
to the teeth if they are eaten for a long time, but this can be removed easily 
with attention and dentifrices; and there are not lacking persons who prefer 
these to all the other spring fruits, even those of the Old World. The tree 
flowers in spring and bears fruit nearly all summer long. It thrives in tem- 
perate regions, such as Mexico, where these trees grow in the gardens and 
plains, cultivated or wild. The decoction of the bark, put in the sun for 
fifteen days, and drunk in a dose of a drachm, cures dysentery; and the pow- 
dered bark removes ulcers from the eyes. clears the vision, and relieves in- 
flammation of the eyes; and it moistens the tongue if it be dry from burning 
fever, as does also the liquor or juice from the young shoots.”

““yslay”’). 

The fruit of the holly-leaf cherry is edible, but the fiesh, although of good 
flavor, is very scant. It is gathered by the people of Baja California. The 
Coahuilla Indians of California made use of the seeds for food. These were 
gathered in large quantities and spread in the sun to dry. They were then 
eracked and the kernels extracted and crushed in a mortar, then leached in a 
sand basket through which water was poured. The meal thus obtained was 
made into atole.

“xicaco”’ (Oaxaca, Seler). 

The English names are “ cocoa-plum ” and “ pigeon-plum.” The bark, leaves, 
and root are astringent and have been used for dysentery, etc. The leaves and 
fruit furnish a black dye. The seeds contain a large amount of oil, and by the 
Caribs they were strung on sticks and burnt like candles. The seeds are edible 
also. The fruit is highly valued in some parts of Mexico and elsewhere in tropi- 
cal America and was a favorite food of the Caribs. It is astringent until per- 
fectly ripe, when it is sweet and insipid. It is eaten raw but more often made 
into preserves, which are sold in Mexican markets. For an illustration of a 
fruiting branch see Contr. U. S. Nat. Herb. 8: pl. 26. 

The ‘“ hicaco” is well described by Oviedo (Lib. VIII, Cap. IX). ‘“ The skin 
of the fruit,” he writes, “ has some resemblance to that on a monkey’s face; for 
no matter how young a monkey is, it seems old because of its wrinkles, and like- 
wise the hicaco fruit, no matter how fresh it may be, is always full of wrinkles.”

Trees or shrubs, often armed with spines; leaves usually bipinnate, rarely 
pinnate; flowers usually small but often showy, capitate, spicate, or racemose ; 
ealyx usually 5-lobed or 5-parted; petals usually 5, free or connate; fruit 
a legume, but very variable in form. 

In many members of this family the leaves are ‘“ sensitive,” that is, they 
respond when touched or struck by folding their leaflets together. They also 
often act in the same way upon the approach of darkness or during excessively 
dry weather. A few herbaceous representatives of the family occur in Mexico.

fence posts, tool handles, ete., and in the Rio Grande Valley it is an important 
source of fuel. The fruits are edible like those of P. juliflora, and are used in

‘ much the same way. They are so sweet that they can be eaten as picked, 
without any special preparation. The Indians of the Colorado River region 
obtained a fermented drink from the pods, and by boiling them they prepared 
a sirup. The Pimas of Arizona cooked the poods in a pit lined with the stems 
of Tessaria borealis, alternating them with layers of cocklebur (Xanthium 
sp.) leaves. The pit was covered with earth and left three or four days 
before being opened. The pods were then’spread in the sun, dried, and stored. 
Later they were pounded into a fine flour, which was eaten ‘in the form of 
pinole. The Pimas also used a decoction of the root bark as a dressing for 
wounds, and as the wound healed the dried and pulverized bark was substi- 
tuted.

reported: “ Guisache” (Michoacan, Guerrero) ; ‘“‘ chfiicata” (Michoacan, Taras- 
ean); “tziritzequa” (Michoacin, Ramirez); “algarroba” (Colima, and in 
Many Other regions) ; ‘“ mezquite blanco,” ‘‘ mezquite amarillo,’ “ mezquite colo-

(Otomi, Buelna). 

One of the best-known plants of Mexico and of the ar’d regions of the United 
States; in Mexico often planted as a shade tree. In the more arid regions the 
mesquite is usually a shrub, and it is only when fairly well supplied with water 
that it becomes a tree. It thrives best in river valleys, where it attains the 
greatest size, but on plains and mesas it is often abundant, frequently, indeed, 
being the most characteristic plant for many miles, and forming thickets or for- 
ests. The smaller trees are strikingly suggestive of peach trees, for which they 
are often mistaken by inexperienced eastern travellers viewing them for the 
first time from the train as they cross the State of Texas. The larger individuals 
are much like apple trees in habit. The wood is valuable for many purposes, 
such as railroad ties, carts, fence posts, charcoal, fuel, etc. In Texas it has been 
used for paving blocks for streets. The wood and bark are employed for tan- 
ning. In the northern part of its range the shrubby form develops enormous 
underground stems (known in Chihuahua as “ cepas’’) which, in many places 
are the most important source of fuel. They require a great amount of labor to 
remove them from the earth, but they form excellent firewood. The smaller 
roots penetrate the soil to a great depth, sometimes, it is said, for as much as 15

to 23 meters. The Seri Indians of Tibur6n Island use the root fiber for cordage, 
wetting the roots in water, and sometimes they manufacture a coarse fabric 
from the fiber. The wood of the roots is very hard, and the Pima of Arizona 
employed it for their war clubs and for plows. 

The gum which exudes from the trunk (“ goma de mezquite,” “ goma del pais,” 
“ mizquicopalli”’) is amber-colored and translucent, similar to gum arabic, for 
which it is often substituted in Mexico. Dissolved in water it makes excellent 
mucilage, and its infusion is used for dysentery and as a gargle for throat affec- 
tions; by the Pimas a solution of it was used for treating sore eyes and open 
wounds. It is sometimes employed in making candy. The flowers are much 
frequented by bees, and yield a good grade of light-colored honey. The Pima 
Indians sometimes eat the flower spikes, stripping off the flowers between the 
teeth. The same tribe employs the inner bark of the mesquite as a substitute for 
rennet, and a decoction of it as an emetic and cathartic. 

The pods are, perhaps, the most important part of the plant. When chewed 
they are sweet, for they contain much sugar, the pulp being composed of 25 to 
30 per cent of grape sugar. They are eaten by stock of all kinds and where the 
plants are abundant are important for forage. In Hawaii, where the mesquite 
is naturalized, the fruits have become an article of some commercial importance 
because of their use for stock feed. They are gathered in large quantities and 
ground into meal. It is of interest to note that in the early days of the Spanish 
occupation, when ships traded regularly every year between Acapulco and 
Manila, the mesquite was introduced into the Philippines and has now become 
naturalized there. It was even described from that country as a new species, 
Prosopis vidaliana Naves. The pods have long been an article of human food 
in North America, and are still so used to some extent, especially by the Indians. 
Among some of the tribes, as with the Pimas, they were the chief food staple. 
They are ground into a meal from which the seeds and coarser parts of the 
pods are removed. The Apaches and other tribes often made use of holes or 
depressions in the rocks as a mortar for grinding the pods, and these holes are 
now of common occurrence in the mountains where mesquite plants are found. 
The meal is made into cakes (known in Mexico as “ mezquitamales’”’) which are 
baked, or it is mixed with water to form a beverage known as * mezquitatole.” 
The meal is also mixed with water and fermented to make a kind of beer. 

The mesquite is discussed by Sahagtin under the name ‘“ mizquitl.” “ From 
the bark,” he writes, “they prepare a drink which takes the place of pulque,” 
a statement whose accuracy is questionable. He reports that the juice of the 
leaves and young shoots is dropped into the eyes to relieve affections of those 
organs. Hernandez? also treats of the plant in a chapter entitled “ De Mizquitl, 
seu Siliqua Acatiae.” He states that the Chichimec Indians make cakes from 
the pods, and, incorrectly of course, that the tree “is the true Acacia of the 
ancients, which furnishes Gum Arabic.” The tree is mentioned also by Clavi- 
gero (Historia de California, 1789), who says, but doubtless erroneously, that 
it is introduced in that region. He also mentions the use of the juice for the 
relief of eye affections (a practice still followed in Mexico to the present day), 
and he reports that the Cochimi name of the plant is “ guatra.” 

Prosopis juliflora is a variable species, but there seems to be no satisfactory 
basis for separation of the forms. Some of the Mexican material exactly matches 
that from Jamaica, but many specimens approach the two following forms. It 
may be mentioned, incidentally, that the early writers state that the mesquite 
‘of Jamaica is not a native plant, but was introduced in early days, very probably 
from Mexico.

Berlandier* once applied (but without technical description) the name J/i- 
mosa “ pseudo-echinus”’ to this species, because of the resemblance of the leaves 
to those of “ Hchinus Molle,” the “Arbol del Pert.” The latter Latin name, of 
course, is a typographical (?) error for Schinus molle.

This form is usually distinguishable from the typical juliflora by the small 
pubescent leaflets. There are so many intermediate specimens, however, es- 
pecially in Mexico, that it is not possible to recognize the form as a species. 
In case the plant should receive such recognition, the proper name for it is 
Prosopis odorata Torr. That name was based upon a flowering specimen of 
the present plant and fruit of P. pubescens, and for that reason has been 
discarded by most writers. Taking into consideration the specific name, 
“‘ odorata,” it seems reasonable to typify the name by the flowering specimen. 

Prosopis articulata was based upon a form in which the pods are strongly 
constricted between the seeds. Specimens examined show great variation in 
this respect, the prominence of the constrictions being dependent, apparently, 
upon the amount of fleshy matter developed in the valves.

If the material from the West Indies and the United States were studied 
without reference to that from Mexico, as has been done, apparently, by 
recent writers, Prosopis glandulosa might well be considered a distinct species. 
In Mexico so many intergrading plants occur that it can not be regarded as 
more than a form of P. juliflora. The leaflets are usually glabrous, but often 
they are quite as pubescent as in P. juliflora velutina. Specimens from Peru 
and Argentina are so like the plant of the United States that if they were 
labeled as coming from the latter country no one would question their determin- 
nation as P. glandulosa.

364 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


Shrub or small tree, sometimes 6 meters high; leaflets 4 to 6 mm. long; 
flowers white; fruit broad, thin, sparsely hispid on the valves. “Rabo de 
iguana” (Guerrero); ‘‘uha de gato” (Oaxaca). 

It is possible that M. curycarpoides is distinct, but it is known only frem 
flowering branches, which show no essential differences from M. euryearpa. 
The fruit originally described as belonging to M, eurycarpoides is probably that 
of Acacia farnesiana. 


51. Mimosa colimensis Robinson, Proc. Bost. Soc. Nat. Hist. 31: 358. 1904. 

Known only from Colima, the type locality. 

Shrub, armed with short recurved spines; leaflets 5 to 7 mm. long; flower 
heads racemose-paniculate.

small recurved spines; leaflets mostly oval, 7 to 14 mm. long, obtuse or acute; 
flowers white, sweet-scented; fruit 5 to 7.5 cm. long, 1 cm. wide, glabrous. 
“ Raspa-huevos ” (Nuevo Leén, Tamaulipas) ; “ raspilla”’ (Tamaulipas). 

53. Mimosa wootonii’ Standl., sp. nov. 

Type from Hacienda Buena Vista, Tamaulipas (Wooton, June 14, 1919; 
U. S. Nat. Herb. no. 989828). 

Subscandent shrub, the branches anguiate, glabrous, armed with very nu- 
merous short recurved prickles; leaf rachis 9 to 12 cm. long, with numerous 
recurved prickles, sparsely puberulent with short curled hairs; pinnae 3 or 
4 pairs; leaflets usually 4 or 5 pairs, oval-elliptic, oval, or sometimes obovate- 
oval, 8 to 15 mm. long, 5 to 9 mm, wide, acute or obtuse at apex, mucronate, 
bright green, glabrous, with rather prominent venation; flowers capitate, race- 
mose, the peduncles fasciculate, 1.2 to 2 em. long, puberulent ; calyx and corolla 
glabrous, the calyx one-third as long as the corolla; ovary glabrous. ‘“ Ras- 
pilla,” ‘‘ raspa-huevos.” 

Except in pubescence, this plant is almost exactly like M. malacophylla 
Gray, which was collected at the same locality. It may be only a form of 
that species, but in the latter the pubescence is very copious on all parts, 
consisting of short straight hairs. The quality and quantity of pubescence seem 
to be constant characters in the other Mexican species of the genus.

Mimosa esculenta Moc. & Sessé, Pl. Nov. Hisp. 178. 1887. 

Jalisco to Puebla and Chiapas; type from ‘“ Nova-Hispania.”’ 

Tree, 6 to 15 meters high; leaves often 40 cm. long, the leaflets linear, 3 to 
4 mm. long, glabrate; flowers white, odorless, the heads 2 cm. in diameter, 
arranged in large racemes or panicles; fruit 12 to 27 cm. long, 2 to 3 em. 
wide, red or purplish. ‘“ Guaje” or “huaje” (Jalisco, Mexico, Morelos, Oa- 
xaca; derived from the Nahuatl huazin, hoatzin, or hoazrin) ; “ uachi blanco” 
(Chiapas) ; “ huassi,” “ guaxi”’ (Otomi, Pejfafiel). 

Sessé and Mocifio state that the pods were an article of commerce and that 
the seeds, in spite of their unpleasant flavor, were eaten by the Indians, who 
believed that they possessed aprodisiac properties. The seeds are still eaten 
in Mexico, usually with salt. 

This is probably the plant of which Sahagtn writes: “ There is a tree known 
as uazin. It is of medium size; its trunk is smooth, likewise the leaves, which 
are almost like those of the 4rbol del Pert [Schinus molle]. It bears a fruit 
like that of the carob, which is good to eat and is offered for sale in the 
markets.” 

According to Robelo, the geographic name Oaxaca takes its derivation from 
the word huazin, the Nahuatl form being Huaxyacae, or “place where the 
huazin begins to grow.’ The word Huaxtl signifies “where the huaxin 
abounds,” and Huajuapan “river of the huazin.” P

The seeds are sometimes used for making necklaces, bracelets, and other articles. 
Grosourdy reports that the roots have emmenagogue and abortive properties. 
The plant has been introduced into the tropics of the old World, where it is 
sometimes planted for hedges. It grows readily from cuttings. Its most com- 
mon English name is “ lead-tree,” but in the Bahamas it is known as “ jumby- 
bean.”

9. ACACIA Willd. Sp. Pl. 4: 1049. 1806. 


REFERENCE: Benth. Trans. Linn. Soc. Bot. 30: 444-533. 1875. 

Trees or shrubs, rarely herbs, usually armed with spines; leaves bipinnate, 
the leaflets usually small and numerous, the petiole usually glanduliferous; 
flowers small but often showy, capitate or spicate, the stamens numerous 
(sometimes as many as 400), exserted; fruit very variable in form. 

The species of Acacia are widely distributed in the tropics of both hemis- 
pheres, being particularly abundant in Australia. Many of them yield useful 
gums, gum arabic being furnished by A. scorpioides (L.) W. F. Wight [A. 
arabica (Lam.) Willd.] and other species. This gum is employed in medicine 
as a remulcent and has varied uses in different industries. 


A. Spines very large, most of them 5 mm. wide at the base or often much 
broader, either inflated and then usually punctured by ants or flattened 
and sword-shaped, never abruptly recurved, sometimes boat-shaped.

terete or nearly so, whitish, pale brown, or yellowish; leaflets oblong-linear, 5 
to 8 mm. long; flowers yellow; fruit about 5 ecm. long, red or reddish brown, 
with a very long sharp beak. ‘“ Cornezuelo” (Tamaulipas) ; “ zubin,” “ zubin- 
ché” (Yucatén, Maya). 

The seeds are imbedded in abundant pulp. In this, as in the following species 
(nos. 6 to 10), the bull-horn acacias, the large spines are usually inhabited by 
ferocious ants, which enter the spines by a puncture near the apex. These ants 
subsist upon nectar of the large pale glands which are borne as appendages upon 
the tips of the leaflets.

The spines vary greatly in form and color in this and related species, 
so that it is doubtful whether they afford characters of any value for the 
separation of species. The bark is employed in Sinaloa as a remedy for 
scorpion stings.

mm. long; flowers yellow, in small heads. 

A. chiapensis Safford’ is probably the same species, but since it was described 
from fruiting specimens and A. globulifera from specimens with flowers, it 
is impossible to be certain. A. chiapensis was based on specimens collected near 
San Fernandino, Chiapas. It is a shrub or small tree, 3 to 5 meters high.

* Richard Brinsley Hinds was an officer of H. M. 8. Sulphur, a British ship 
which was engaged from 1836 to 1842 in surveying the western coast of America, 
the field of operations extending from Peru to Alaska. The botanical collections 
were obtained by Hinds, Dr. Sinclair, an officer of the ship, and George Barclay, 
a gardener from Kew. Plants were collected in Mexico about San Blas and 
Tepic, and at Cape San Lucas and Magdalena Bay, Baja California. They were 
reported upon by Hinds, the new species being described by Bentham.

In many parts of Mexico the plant is found chiefly about dwellings and 
seems to be naturalized, but in other regions it appears to be native. The wood 
is used for many purposes. The bark and fruit contain tannin and are used for 
tanning and dyeing, and the fruit is often used for making ink. The viscous 
juice of the pods is employed in some places for mending broken china. The 
gum which exudes from the trunk is employed locally in making mucilage; 
it is very similar to gum arabic. The leaves are of value as forage for stock, 
especially in winter. In southern Europe the plant is cultivated extensively 
for theeflowers (known in commerce as cassie flowers), from which perfume 
is manufactured. As much as 100,000 pounds of them are harvested annually 
about Grasse, France. In tropical America the flowers are often laid among 
linen to impart their perfume to it. An ointment made from the flowers is 
used in Mexico as a remedy for headache, and their infusion for dyspepsia. 
The green fruit is very astringent, and a decoction is employed for dysentery, 
inflammation of the skin and mucous membrane, ete. Seler reports even that 
in San Luis Potosi a decoction of the roots is employed as a supposed remedy 
for tuberculosis. The pulverized dried leaves are sometimes applied as a dress- 
ing to wounds. 

This is probably the plant reported from Baja California by Clavigero as 
“huisache.’”’ The pods, he states, were used there for making ink. Cattle, 
he says. are fond of the tender branches, but these impart a bad flavor to their 
flesh. ;

Chihuahua to Sinaloa, Mexico, and Chiapas. Guatemala. 

Shrub, 1 to 4.5 meters high, with blackish bark; leaflets very numerous, linear- 
oblong, 2.5 to 5 mm. long; flowers purple, showy ; fruit densely hirsute or hispid. 
“Cabeza de angel” (Mexico) ; “cabellos de angel” (Guanajuato, Costa Rica, 
Guatemala, Honduras) ; “ pambetano” (Morelos, Valley of Mexico, Veracruz) ; 
“cabellitos de Angel” (Morelos) ; “cabellitos de una vara” (Morelos, Rami- 
rez); “hierba del Angel,” “lele”’ (various localities, Ranvirez) ; “ tepachera ’’ 
“timbrillo” (Valley of Mexico, Ramirez) ; ‘ tepexiloxochitl” or ‘“ tepejiloxo- 


chitl” (=mountain+corn silk+flower), “ texoxochitl” ‘“ tlacoxiloxochitl ” 
(=rod or bush+corn silk+flower), ‘ tlamacazatzotl,”’ “ tzonxochitl,” ‘“ xiloxo- 
chitl,” ‘“ xiloxochicuahuitl” (the shrub) (Nahuatl); “canela,”’ “hierba de 


canela” (Oaxaca, Reko); “coquito” Oaxaca, Seler); “carboncillo” (Costa 
Rica) ; ‘ cabellito””’ (Sinaloa). 

The plant is sometimes used for tanning. The root is used to retard fermenta- 
tion in a drink, ‘‘ tepache,” made from pulque and coarse sugar. The plant is 
said to contain a glucoside, calliandrine. In domestic medicine it is used for 
fevers, especially malaria, although experiments have indicated that its repu- 
tation for this purpose is not justified. 

The plant is treated at length by Hernaindez* in a chapter entitled ‘“ De 
Tlacozilorochitl flore Barbato,’’ which is accompanied by three good figures. 
His account is as follows: “ Tlacozilorochitl, which some call Tentzonxochitl 
[=beard-flower], some J'lamacazcatacotl [=priest-bush], and others Tepexiloxro- 
chitl or Tlalxilochtl [=dwarf hair-flower], is a shrub with leaves like mes- 
quite. The flowers are like long red hair, and they come from round reddish 
berries. The root is fibrous, yellow outside, and red within when it is cut. The 
stalks are red and the pods yellow. It grows in level or mountainous places 
and sometimes along streams. The root bark is dry and astringent and some- 
what glutinous; its nature is hot, in the third order, and its flavor sharp. The 
flowers, crushed, mixed with water, and used as drops, are a wonderful remedy 
for diseases of the eye, for they correct inflammation and remove morbid growths, 
and heal ulcers. If the decoction or infusion of the juice is drunk, it stops 
diarrhoea and dysentery, stimulates the appetite, and relieves indigestion. There 
be those who say also that it soothes the chest, relieves the belly, removes the 
bile by vomiting, and is also a remedy for coughs.” 

This species has usually been known as Calliandra grandiflora (L’Hér) 
Benth., but as pointed out recently by Macbride* that name can scarcely apply 
to the common Mexican species. Macbride states that ‘ There is no reasonable 
doubt but that it is rather referable to C. houstoni (L’Hér.) Benth.,” but the 
same objections that prevent its application to the common Mexican plant also 
prevent its reference to synonomy under the latter species. ;

Sonora to Tamaulipas and Chiapas; type from Veracruz. Guatemala and 
Honduras. 

Shrub or small tree, 1 to 6 meters high, pubescent or glabrate; bark red- 
brown; leaflets 4 to 7 mm. long, the upper surface with a metallic luster; 
flowers purplish red, large and showy; fruit about 1.5 cm. wide, densely brown- 
hirsute. ‘Charamusco” (Tabasco); “hierba burro” (Chiapas); ‘ pambo- 
tano” (southern Mexico); “day,” “tabardillo” (Sinaloa). Probably the 
names reported for C. anomala apply also to this species. 

The same properties are attributed to this as to C. anomala. The bark is 
chewed to harden the gums (in Sinaloa). According to the U. S. Dispensatory, 
the root bark, under the name of “ pambotano bark” (sometimes written errone- 
ously as “pandotano’’) has been highly recommended in Europe as an anti- 
periodic. It is said also to contain an alkaloid which produces death by systolic 
arrest of the heart.

The tree grows rapidly and makes an excellent shade tree because of its 
broad top. The large trunks are used for canoes, water troughs, ete., and the 
wood is very durable in water. It is employed in carpentry and cabinetwork. 
The pods are said to be an excellent feed for cattle, and the seeds as well as 
the young pods are sometimes cooked to be used for human food. The fruit 
and bark are rich in tannin. Rose reports that in Sinaloa the bark and fruit 
are used as a substitute for soap in washing woolen goods and that a syrup 
made from the bark is used for colds. The fruit is used as a soap substitute 
in Venezuela also, The gum which exudes from the trunk is employed in 
Sinaloa as a remedy for bronchitis.

diameter, the bark grayish; pinnae one pair, the leaflets one pair, 2.5 to 5 em. 
long or larger, obtuse, pale green, glabrate; flowers yellowish or greenish

seeds black, surrounded by a white or reddish aril; wood moderately heavy, 
flexible, strong, reddish brown. ‘“ Huamtchil,’ “cuamftchil,’ or “ guamfichil ” 
(used widely in Mexico; from the Nahuatl names, which are given variously as 
cuaumochtl, quauhmochitl. coacamachalli, or quamochitl); ‘“ guamtchitl,” 
“guamuche,” “humo” (Tamaulipas); ‘“ guaymachile” (Guerrero, Palmer) ;

“mochigtiiste”’ (Costa Rica); “ guachimole,” “mongollano” (El Salvador) ; 
“jaguay” (Guatemala); “inga” (Cuba); “camachile” (Guam, Philippines). 

It is of interest to note that the Nahuatl name was introduced, along with 
the plant itself, into Guam and the Philippines by the Spaniards. The word 
has been modified there into such forms as “ camanchil,” “ camonsil,” “kama- 
chiles,” and “camachile.” From the Philippines the tree was carried to India, 
where it is now much planted. The pods are known in India as “ Manila 
tamarinds.” 

The tree is very resistant to drought. It is nearly evergreen, but loses its 
old leaves as the new ones appear. The wood is widely employed for general

eonstruction purposes, for fence posts, and for fuel. The bark yields a yellow 
dye, and is much used for tanning skins; it is used in domestic medicine, also, 
because of its astringent properties. The gum exuding from the trunk is trans- 
parent and deep reddish brown; dissolved in water it makes good mucilage. 
The flowers are much frequented by bees and yield a good quality of honey. 
The fruit is highly esteemed in Mexico and is a common article in the markets. 
The acidulous aril surrounding the seeds is eaten and is used in the preparation 
of a beverage similar to lemonade. Stock of all kinds are fond of the pods, and 
in India monkeys are said to eat them greedily. 

The tree is treated by Hernandez’ in a chapter entitled ‘De Coaca machalli, 
seu Maxilla Colubri.”’ This name (“ snake-jaws’’), he states, is given because 
the pair of leaflets somewhat resemble the jaws of a snake. ‘“ The leaves,’’ he 
says, ‘“ applied as plasters, allay pain, even those of venereal sores, and relieve 
convulsions. In flavor they are astringent, sweet, and somewhat glutinous, and 
in temper to a certain extent cold, or moderately warm.” The tree is treated 
on page 94 of the same work, in a chapter headed ‘“‘ De Quamochitl, seu arbore 
fructus crepitantis.” In this account he states that the root bark is good for 
dysentery; the leaves, with salt, cure indigestion, and also produce abortion; 
the juice of the seeds, sniffed into the nose, draws off humors from the head; 
and the pulverized seeds (especially if mixed with rue) cleanse internal ulcers. 


5. Pithecollobium unguis-cati (L.) Mart. Hort. Monae. 188. 1829. 

Mimosa unguis-cati L. Sp. Pl. 517. 1753. 

Chiefly in coastal thickets, Tamaulipas to Yucatan; Sinaloa. West Indies; 
northern South America; type from Jamaica. 

Shrub or small tree, sometimes 9 meters high, with a trunk 30 em. in diame- 
ter, very spiny, the bark reddish brown or gray, shallowly fissured ; leaves more 
or less persistent, the pinnae one pair, the leaflets one pair, obliquely obovate or 
oval, 2 to 4 em. long; flowers greenish yellow, sweet-scented, the long stamens 
purplish; fruit 8 to 12 cm. long, 0.6 to 1.2 em. wide, twisted, reddish brown; 
seeds dark brown or blackish, surrounded by a red aril; wood very hard, close- 
grained, red or purple, with yellow sapwood, its specific gravity about 0.90. 
“Tzim-ché,” “ tzin-ché”” (Yucatan, Maya, Seler); “espino de playa” (Nica- 
ragua) ; “espinuelo” (Venezuela) ; “dinde” (Colombia) ; “‘manca montero” 
(Cuba) ; “ufia de gato” (Nicaragua, Cuba, Porto Rico) ; “rolon” (Porto Rico). 

The English names applied to the plant are “ cat’s-claw,” ‘ black-bead,”’ and 
** bread-and-cheeses.” 

The bark is astringent, and diuretic and tonic properties are ascribed to it; 
it has been used for fevers and kidney diseases as well as for treating sores. 
Barham reports that the plant was much used in Jamaica in domestic medicine, 
and that it was “a sovereign remedy for the stone and gravel,” as well as for 
affections of the liver and spleen. The Spaniards, he relates, said that the 
black seeds resembled the kidneys and the white aril the fat surrounding those 
organs, hence, by the doctrine of signatures, the belief that the plant was a 
remedy for kidney affections. The fruit is said to be rich in tannin and to 
yield a yellow dye.

smooth, gray; leaves persistent. the pinnae 2 to 5 pairs, the leaflets 10 to 20 
pairs, 4 to 8 mm. long, pubescent or glabrate; flowers yellowish white; fruit 
flat, straight, 7 to 12 cm. long, about 1.5 em. wide; wood hard, close-grained, 
dark reddish brown, very heavy. ‘‘Tenaza” (Nuevo Le6n, Tamaulipas) ; 
“huajillo”’ (Texas); “ guajilla” (Tamaulipas). 

The tree is of some importance for forage, the leaves being eaten by goats 
and sheep in winter. The wood is used for various purposes. Specimens col- 
lected in Oaxaca probably belong to this species, and others from Sinaloa (where 
the plant is known as ‘“ carbonera’’) are probably conspecific.

Yucatan and Campeche; type from Campeche. 

Tree, sometimes 20 meters high; leaflets numerous, 3 to 6 mm. long; fruit 
about 10 cm. long. “ Chucum” (Yucatan) ; “ huisache’”’ (Campeche, Ramirez). 

The tree is said to produce a gum similar to that of mezquite. The fruit is 
reported to contain 18 per cent of tannin, and to yield a black dye. 

It is probable that the present material is referred here correctly, although 
it does not quite agree with Bentham’s description, especially in regard to the 
fruit. The type collection was without fruit, and Bentham’s description of it 
was based, presumably, upon specimens from Hidalgo, which may have belonged 
to some other species.

Unarmed trees or shrubs; leaves even-pinnate, the leaflets few, large, the 
petiole often winged; stipules small; flowers large, spicate or capitate; fruit 
large, the seeds imbedded in a pulp. 

The fleshy pulp surrounding the seeds is edible, and the pods are often seen 
in the markets. The wood is said to be weak and fibrous, with a specific gravity 
of 0.54 to 0.67, and to be of little value except for charcoal and firewood. Some 
of the species are often planted to shade coffee bushes and as windbreaks to

The seeds are sometimes employed as a substitute for coffee. The plant is 
used in domestic medicine for its reputed tonic, diuretic, stomachic, and febri- 
fuge properties. It is employed especially for dropsy, rheumatism, fevers, and 
venereal diseases. An infusion of the leaves has been employed by the regular 
physicians of the French colonies of western Africa in the treatment of yellow 
fever, with good results according to reports. The plant is used also, in the 
form of an ointment, as a remedy for ringworm, eczema, and other cutaneous 
diseases, 

This species is figured by Hernindez,? and described in a chapter entitled 
“De Hceapatli, seu parva Sambuco.” His account is as follows: “ Hepatli, 
which some call Tlaloazin, some Totoncazihoitl, or hot medicine, some Xomo- 
tontli, or little elder, and others Xiopatli, is a hairy shrub, with leaves like’ 
the almond, and smooth, purplish, slender, round stems. On the tips of the 
branches are borne the yellow flowers, from which spring the pods, which 
are slender, round, and long, filled with purplish seeds, like lentils but smaller, 
of heavy odor and bitter flavor. The shrub grows in fields of the hot and 
temperate regions, and is often cultivated about houses and gardens because 
of its medicinal virtues. Its nature is hot and dry and somewhat astringent. 
It cures tumors and ulcers and calms ear-ache. The,leaves, crushed and 
applied as a plaster to the belly, benefit infants who vomit their milk; and

applied likewise to the head they alleviate pain; and applied everywhere to 
the body, or taken in the quantity of a handful, they relieve fever chills. 
Some say that in this manner it cures indigestion also, that its application 
helps that form of leprosy which the Indians call Xiotl.”

Collected at Acapulco, but perhaps only cultivated; reported from Tabasco. 
Central America, West Indies, and South America. 

Tree, 4 to 10 meters high or larger; leaflets large, oblong, 10 to 20 pairs, 
pubescent; flowers large and showy, racemose, white or pink; fruit 45 to 60 


em. long, about 3.5 cm. in diameter. “ Cafiafistula grande” (Tabasco) ; 
“ cafiafistula ” (Guerrero); “carao” (Costa Rica, Nicaragua, El Salvador) ; 
“sandal” (Costa Rica); “cargo” (El Salvador, Honduras); “ cafiafistula 


gruesa,” “ cahnandonga ” (Colombia) ; “ caraémano” (Nicaragua) ; ‘“ cafiafistula 
cimarrona ”’ (Porto Rico). 

The fruit is filled with a bitter pulp, which has laxative properties and is 
used in the treatment of fevers. 

It is probably this species which has been reported frequently from Mexico 
as C. fistula L. The writer has seen no Mexican specimens of the latter, 
although it may occur in Mexico, at least in cultivation. The following 
Mexican names names are reported for C. fistula: “ Cafiafistula,” “ quauhayo- 
huachtli,” ‘quauhuayo.” It has been reported from Oaxaca, Campeche, 
Morelos, and Veracruz. 


13. Cassia tora L. Sp. Pl. 376. 1753. 

Baja California and Sonora to Chiapas and Veracruz. Widely distributed in 
the tropics of both hemispheres. 

Plants ill-scented, glabrous or nearly so, usually herbaceous but sometimes 
fruticose and a meter high; leaflets obovate or rounded-obovate, 2 to 5 em. 
long, rounded at apex; flowers large, yellow; fruit 15 to 20 em. long, 3 to 4 
mm. wide. “Dormilén” (Costa Rica); “biche manso” (Sinaloa); “ ejotil” 
(Guatemala, Honduras, Blake). 

The leaves are said to have the purgative properties of the senna of com- 
merce. In the Old World tropics they are sometimes cooked and eaten. In 
India the plant bears a great reputation as a remedy for ringworm and other 
cutaneous diseases. It is sometimes cultivated there for the seeds, which are 
used as a mordant in dyeing cloth blue. The seeds are sometimes employed 
in Mexico as a substitute for coffee, and it is said that they have been im- 
ported into Europe from the tropics for use in adulterating that article. In 
India the leaves are fried in castor oil (oil of Ricinus communis) and applied 
to ulcers; they are also crushed and used to relieve the pain of insect stings, 
and employed as poultices to boils to hasten suppuration. In the same country 
the seeds, ground and mixed with buttermilk, are employed to relieve itching 
eruptions of the skin.

cruz, Durango, Oaxaca) ; “ café del pais,” (Veracruz, Oaxaca) ; “sen del pais,” 
“hierba hedionda macho” (Porto Rico); “frijolillo” (Guatemala, Honduras, 
Blake). 

Seeds sometimes used as a substitute for coffee. The plant is said to have 
purgative properties, and is used in Mexico as an emmenagogue. Sornay states 
that the plant has been suspected to be poisonous. 

This species is figured by Hernandez’ and discussed in a chapter entitled ‘‘ De 
Chatalhuic Cassia Silvestri.” The figure applies to this plant, but the descrip- 
tion does not agree in all particulars. He speaks of it as ‘“ chatalhuic, which 
some call Cacaotl or Casia fistula.” ‘The bark,’ he says, ‘‘ which is hot and 
dry in the fourth degree, is light or dark in color; powdered and drunk in the 
quantity of two drachms in water in the morning it purges the bile and phlegm, 
and expels worms if there are any in the body. It is esteemed as an excellent 
drug by the natives. The same bark, mixed with Agvin and supplied behind 
the ears, cures earache. The rind of the fruit, which is sweet and in flavor simi- 
lar to that of Cassia fistula, drunk in the same manner and quantity, purges 
the bile and phlegm, soothes the belly, and acts as a gentle purgative. The same 
rind, pulverized and infused in water (a comb being wetted with it), restores 
the hair and makes it grow long. The seeds, ground and mixed with water and 
drunk, soothe fevers. All of which things have been proved by a thousand 
experiments.” On page 376 of the same work there is figured, without descrip- 
tion, “‘ Ecapatli altera,’” which also is probably of this species.

vated, probably. Widely distributed in tropical America. 

Shrub, 1 to 4 meters high; leaflets oval to oblong, 6 to 17 cm. long, rounded 
at apex, glabrate; flowers large, lemon-yellow, racemose; fruit about 15 em. 
long, each valve with a broad thin wing. “Flor del secreto” (Yucatan,

Blake) ; “ talantola,” “talantro” (Porto Rico); “ guajavo” (Santo Domingo). 

In Jamaica the plant is known as “ringworm shrub.” It is a very hand- 
some shrub when in flower. In Guam and the Philippines it is called “Aca- 
puleo,” doubtless from the fact that it was introduced into those islands by 
the ships which sailed between Acapulco and Manila. In the Philippines this 
name has also been modified as “ Capuleo” and ‘‘ Capurco.” Reko refers the 
Nahuatl name “ecapatli” to this species, and states that the plant was em- 
ployed by the Aztecs for syphilis. He refers here also the name “ totoncaxi- 
huitl”’ (“fever-herb”), and states that the plant found use also as a remedy 
for fevers. 

The leaves are said to have purgative, diuretic. and sudorific properties, and 
they are employed widely as a remedy for ringworm and other cutaneous dis- 
eases. The decoction of the plant has been used in the West Indies for ve- 
nereal diseases, as a remedy for snake bites, and to destroy chiggers. Drury 
reports that it is widely used by Hindoo physicians for all sorts of poisonous 
bites. For an illustration of the plant see Contr. U. S. Nat. Herb. 8: pl. 39.

2. TAMARINDUS L. Sp. Pl. 34. 1753. 


1. Tamarindus indicus L. Sp. Pl. 34. 1753. 

Widely cultivated in Mexico, as well as elsewhere in tropical America, and 
often growing without cultivation. Native of the tropics of the Old World. 

Large unarmed tree, sometimes 15 meters high or more, with widely spread- 
ing crown, the bark brown; leaves pinnate, the leaflets numerous, oblong, 1 
to 2 em. long; flowers large, yellow, striped with red, racemose; fruit large, 
brown, rough, thick, indehiscent, the 4 to 7 brown seeds surrounded by a juicy 
red pulp; wood fine-grained, dirty white or yellowish, its specific gravity 
said to be about 0.94. Known generally as “ tamarindo;” the name “ huaje” or 
“hoaxin ” is said to be used in some localities. 

The tamarind was introduced into Mexico soon after the Conquest, and is 
now a common tree in many regions. The wood is of some local importance. 
It is valuable for building purposes and furnishes excellent charcoal for the 
manufacture of gunpowder. In India the leaves are used to give a yellow 
dye and the seeds, young leaves, and flowers are eaten. The fruit is the most 
important product of the tree, the juicy, acidulous pulp being eaten and em- 
ployed generally in tropical America in the preparation of cooling beverages. 
It is made also into various kinds of sweetmeats. In some parts of tropical 
America a fermented drink is made from the pulp. 

In India the fruit is much used for flavoring curries, and the seeds are 
often cooked and eaten. The young seedlings also are boiled as a vegetable, 
likewise the leaves and flowers. 

The pulp of the fruit is official in the U. S. Pharmacopoeia. It contains 
sugar and acetic, tartaric, and citric acids. Its fluid extract is laxative and

refrigerant, and an infusion is employed as a beverage in febrile diseases. 
The supply of the fruit for the United States comes chiefly from the West 
Indies; that for Europe from India, the West Indies, and Ecuador. For 
shipment the outer shell is stripped off and the pulp preserved with sugar 
or syrup. In Madagascar a decoction of the bark is employed for asthma and 
amenorrhoea, and a decoction of the leaves for intestinal worms and de- 
rangements of the stomach. 

The tamarind is described at length by Hernindez.* For an illustration of 
the leaves and fruit see Contr. U. S. Nat. Herb. 9: pl. 66. 


Ceratonia siliqua L., the carob or St. John’s-bread (“ algarrobo”*), a native 
of the Old World, is cultivated at Guaymas, Sonora, and probably elsewhere. 
It has pinnate leaves with large oval leaflets, and large brown pods containing 
a thick edible pulp.

1. Cercis canadensis L. Sp. Pl. 374. 1753. 

Coahuila to San Luis Potosi. Eastern United States. 

Large shrub or small tree, 3 te 12 meters high, the trunk sometimes 30 cm. 
thick; bark smooth, light brown; leaves deciduous, reniform or ovate-orbicular, 
5 to 9 ecm. wide, glabrous or pubescent beneath; flowers pink or purplish, clus- 
tered, appearing before the leaves; fruit flat, thin, 6 to 10 cm. long, 1 to 1:5 em. 
wide, bronze, somewhat glaucous; wood hard, close-grained, yellowish brown, its 
specific gravity about 0.70. ‘“ Pata de vaca” (San Luis Potosi). 

Palmer reports that in San Luis Potosi the flowers are fried and eaten, being 
considered a great delicacy. The bark has mild but very active astringent prop- 
erties, and has been recommended for the treatment of chronic diarrhoea and 
dysentery. 

C. reniformis Engelm. (C. tevensis Sarg.) has been reported from Mexico. 
That species does not appear to be very clearly distinct from C. canadensis. 
The Mexican material at hand seems to represent a single species, and agrees 
better with C. canadensis than with the material that has been referred to C. 
reniformis.

6. HYMENAEA L. Sp. Pl. 1192. 1753. 

Some of the species occurring along the East African coast furnish valuable 
gums which are exported as “copal gum” for the manufacture of varnish. The 
gum is exuded chiefly about the roots, and in some localities deposits of “fossil” 
gum are found, where the trees themselves have disappeared. From 800,000 to 
1,200,000 pounds of the gum are said to be exported annually from Zanzibar.

Hymenaea candolleana H. B. Ix. Nov. Gen. & Sp. 6: 323. pl. 566, 1823. 

Tepiec to Chiapas, Veracruz, and Tabasco. Widely distributed in Central 
America, the West Indies, and South America. 

Unarmed tree, 5 to 25 meters high, or even larger, the trunk sometimes 2 
meters in diameter, sometimes furnished with buttresses, the bark thin, whitish ; 
leaves bifoliolate, persistent, the leaflets obliquely ovate, oblong, or oval, 5 to 10 
em. long, obtuse to acuminate, thick and leathery, gland-dotted; flowers large, 
whitish or purplish, corymbose-paniculate; fruit large, brown, rough, usually 
2-seeded, indehiscent, the valves very thick and hard. ‘“‘ Cuapinol,” “ cuapinole,”’ 
“cuapinoli,” “ coapinol,” ** guapinol,” “ guapinole”’ (Tabasco, Oaxaca, Veracruz, 
Jalisco, Central America, ete.; from the Nahuatl cua-pinolli, sometimes written 
quauhpinoli) ; “nere” (Oaxaca, Zapotec, Reko); ‘copinol” (Guatemala, El 
Salvador) ; ‘ algarrobo” (El Salvador, Cuba, Porto Rico, Panama, Venezuela) ; 
“ quiebra-hacha,” “ curbaril”’ (Cuba) ; “ palito colcrado” (Guatemala, Hondu- 
ras, Blake). 

The name “ courbaril ’”’ is said to be employed in British Guiana and “ jatoba ” 
in Brazil. The wood is very hard, tough, and heavy (the specific gravity re- 
ported as 0.90 and 1.06), and is colored somewhat like mahogany; it is em- 
ployed for general construction, Ship building, furniture, sugar mills, ete., and 
is sometimes exported. The Indians of Brazil use both the trunks and the bark 
for making canoes. The seeds are surrounded by a sweet pulp, which becomes 
mealy when the fruit is ripe. This pulp is edible; it is mixed with water to 
prepare a kind of “atole,’’ which is said to be very nutritious, and is some- 
times fermented to produce an alcoholic beverage. A pale yellow or reddish 
gum (‘‘resina de cuapinole,’” “goma animé de México,” “ambar del pais,” 
“ambar de cuapinole,”’ “succino del pais,’ ‘‘succino criollo,”’ ‘“goma de la 
tierra,” “incienso de la tierra,” “incienso de Petapa’’) exudes from the trunk, 
and is found more abundantly on the roots. In Mexico this has been much 
used for incense in churches, and is employed in making varnish for furniture, 
patent leather, ete. It is sometimes collected in Mexico for export, and this 
tree is supposed to be the source of the ‘‘ gum animé,” of which large quantities 
are shipped from Brazil. This was formerly used in official medicine, espe- 
cially in the preparation of ointments and plasters, but now it is employed only 
in the manufacture of varnish and incense. The fruit contains large resin 
pockets whose contents harden into gum. In the regions where the tree is 
native the gum is sometimes smoked to relieve asthma and is employed locally 
for rheumatism, eatarrh, ulcers, and venereal diseases. The decoction of the 
bark is reputed to act as an arterial sedative and to have purgative vermifuge 
and carminative properties.’ For an illustration of the fruit see Contr. U. S. 
Nat. Herb. 8: pl. 41.

or sometimes bifoliolate; flowers racemose, usually large and showy, the 
racemes often paniculate; fruit flat, indehiscent or bivalvate. 

There are many species of the genus in the East Indies, some of which 
are cultivated in tropical America because of their very showy flowers. Some 
of the Old World representatives yield a gum which, however, is of little 
importance, and the bark of certain species is used for tanning. Others 
have bark which furnishes dyes or from which rope is made, some are said 
to be employed as fish poisons, and some have edible flowers and seeds. Vermi- 
fuge properties are ascribed to certain species, and others are employed as 
remedies for liver affections. 

The following names are reported for Mexican species whose identification is 
uncertain: “Timbe” (Jalisco); “hierba de la vaca” (Durango); “ papalo- 
cuahuite ” (San Luis Potosi).

The wood (logwood) is a well-known article of export and has been ex- 
ported from Mexico, Central America, and the West Indies in vast quantities. 
Formerly its export was the chief industry of Yucataén and Tabasco, and it is 
still shipped in considerable amounts, It is stated that when Grandmont 
captured Campeche he burned more than a million logs stored there. The 
wood is used principally for dyeing, its properties being dependent upon the 
peculiar principle, haematoxylin or hematin, which it contains. Logwood is 
one of the few natural dyewoods which has not been replaced satisfactorily 
by synthetic dyes. Its properties were made known at an early date, and the 
wood was soon an important article of export to Spain from Mexico and the 
West Indies. Acosta relates that in 1587 130 quintals of it were shipped to 
Spain from Santo Domingo. The tree seems to be native in Hispaniola, but it 
was naturalized at an early date in Jamaica and the Bahamas, where it did 
not grow naturally. 

The heartwood is official in the U. S. Pharmacopoeia, being used in medicine as 
a mild astringent, especially in diarrhoea and dysentery. The wood contains 
about 10 per cent of tannin. The seeds are sometimes employed to flavor food.

Haematorylum boreale S. Wats. Proc. Amer. Acad. 21: 426. 1886. 

Chihuahua to Baja California, Oaxaca, and Morelos. Guatemala to Colombia 
(type locality) ; Haiti. 

Tree, similar in habit to the last species, rarely more than 7 meters high, 
often only a shrub; bark dark brown; leaves persistent until the appearance 
of the new ones, the young leaflets usually tinged with bronze; leaflets oblong- 
oval to orbicular, often broadly cuneate, 0.5 to 2 cm. long, rounded or emargi- 
nate at apex; fruit 2.5 to 5.5 cm. long, 0.8 to 1.5 cm. wide, very thin, sessile, often 
red or purple. Known generally as “ brasil” or “* palo de brasil,” but the names 
“palo de tinta” and “ palo de Campeche” are applied in the south; “ azulillo” 
(Oaxaca) ; “ brasileto”’ (Colombia). 

This species has often been confused with the preceding one, and in com- 
merce no distinction is drawn between the two. The wood is equally valu- 
able, and has been exported in large quantities from the west coast of Mexico. 
It is used locally for dyeing various objects and is employed as a remedy 
for jaundice and erysipelas. The plant is described by Hernindez’* in a 
chapter entitled “De Curaqua, seu Brasilio Hispanorum.’ The accompany- 
ing figure is a very poor one and may represent some other plant. He states 
that the plant was called “curaqua” in Michoacéin, “quamochitl” or “ vitz- 
quahuitl” by the Mexicans, and “brasil” by the Spaniards. ‘“ Its wood dyes 
thread red, for it is much like sandalwood. The decoction of the juice is at 
first yellow, but it turns red, and if it is boiled longer, purple, and if mixed 
with alum, red or vermillion. This tree is refrigerant, febrifuge, astringent, 
and corroborative.”

A characteristic strand plant, often forming impenetrable thickets of con- 
siderable extent. The large seeds (known as “nicker-nuts”) are so hard 
that it requires a heavy blow of a hammer to break them. They retain their 
vitality for a long time, and are transported by ocean currents for great dis- 
tances, having been carried occasionally from tropical America to European 
shores. They contain about 23 per cent of oil, which has been extracted in 
some regions. They are very bitter and contain a principle known as bondu- 
cine, which is believed to possess tonic and antiperiodic properties. The seeds 
have been used in domestic medicine (and even employed in Europe in times 
past) as a substitute for quinine, and also as a remedy for dropsy, snake bites, 
and venereal diseases. They are often carried by the natives of tropical 
America as talismans or amulets, and are used by children as marbles. 

It is presumably this species which has been reported from Mexico as 0. 
echinata Lam., a Brazilian species, and said to be. known as “brasil” and 
“hoitzquahuitl ” or “ huitzquahuitl.” The writer has seen no specimens of the 
plant, which may be some other species. It is said to be exported as a dye- 
wood. For an illustration of the seeds see Contr. U. S. Nat. Herb. 9: pl. 15.

The pods contain 25 to 30 per cent of tannin. They are used locally for tan- 
ning and have been exported in large quantities from Mexico and other parts of 
tropical America for that purpose. They have been employed in Mexico for 
making ink and are said to have been so used by the early inhabitants. The 
pods yield a black dye and the wood is said to give a red one. The tree was in- 
troduced into India early in the nineteenth century and has been much planted 
there. One tree is said to yield as much as 100 pounds of the pods. These have 
been exported to England, under the name of “ divi-divi” or “ dibi-dibi,’ where

The English names are “ Barbados-flower,’ ‘“ Barbados-pride,”’ ‘ flower- 
fence,” and “ bird-of-paradise flower.” The flowers are sweet-scented and are 
said to yield a good quality of honey. The fruit contains tannin and is some- 
times used for tanning skins. It is said to give a yellow dye with alum and 
a black dye with iron salts, and the root is reported to yield a red dye. In 
India the charred wood is used to make ink. The large seeds are sometimes 
cooked and eaten when green. In Sinaloa it is reported that a kind of rubber 
is extracted from the seeds and made into balls or “ pelotas.” In domestie 
medicine the plant is employed in many ways. The leaves are sometimes used 
to adulterate senna. The early inhabitants of Mexico used a decoction of the 
leaves for liver affections and as a wash for ulcers of the mouth and throat. 
The flowers are reputed to have purgative, febrifuge, and emmenagogue prop- 
erties, and a decoction is a popular remedy for erysipelas and for inflammation 
of the eyes. In Nicaragua the astringent infusion of the bark is used as a wash 
for the teeth and gums. Infusions of the leaves, roots, or bark are employed 
in various places for colds, fevers, cutaneous diseases, and as a purge, and are 
said even to induce abortion. It is reported that in Guatemala the leaves .are 
thrown in water to stupefy fish. 

A related species, C. gilliesii (Hook.) Wall., known as “ bird-of-paradise 
flower,” is sometimes cultivated in northern Mexico. It is distinguished by 
the copious pubescence and very viscid inflorescence.

Widely cultivated in Mexico as a shade tree and sometimes growing without 
cultivation. Native of Madagascar and tropical Africa, but planted commonly 
in all tropical regions. 

Large tree, usually 10 to 20 meters high, with wide-spreading crown, the trunk 
sometimes a meter in diameter; bark thin, grayish brown, slightly furrowed ; 
leaves bipinnate, deciduous, the leaflets numerous, oblong, 4 to 10 mm. long, 
pubescent ; flowers racemose-corymbose, the petals 5 to 7 cm. long, orange-red 
or scarlet; fruit dark brown, flattened, often 60 cm. long; wood whitish or yel- 
lowish, close-grained but soft and weak, its specific gravity about 0.83. ‘“ Tabu-

ico, Guam, Philippines); “pata leén” (Tamaulipas); ‘‘caballero” (Philip- 
pines). 

The English names are “ flame-tree,” “ royal poinciana,” and ‘“‘ peacock-flower.” 
This is one of the most widely planted trees in the tropics, and when covered 
with its huge bunches of brilliant flowers it is extremely showy. When leafless 
the trees are rather unsightly, and their wood is so weak that they are often 
broken by wind. For an illustration of the tree see Contr. U. S. Nat. Herb.

The foliage and young branches are eaten by stock. The wood is used for 
fuel, and has been employed for making paper. The infusion of the leaves is 
employed locally as a febrifuge and sudorific, a remedy for epilepsy, and an 
abortefacient.

By the Pima Indians of Arizona the pods were eaten, either as gathered or 
after having been ground in a mortar. The coarse meal thus obtained was 
sometimes mixed with that of mesquite pods. The wood was used for making 
small articles, such as ladles.

434 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


Unarmed tree, sometimes 17 meters high, with gray bark; leaves pinnate, the 
leaflets 7 to 11, ovate or oval, 3 to 7.5 em. long, obtuse to acuminate, lustrous, 
coriaceous at maturity, with numerous translucent dots and lines; flowers whit- 
ish, racemose; fruit about 7 cm. long, 2 to 3 cm. wide, indehiscent, the apex 
thick and 1-seeded, the basal portion long and broadly winged. “ Naba” 
(Yucatin, Tabasco, Maya) ; “‘chucte” (Veracruz) ; “ balsamo,’” “ arbol de b4l- 
samo,” ‘‘ palo de balsamo” (Veracruz, Chiapas, Guatemala, etc.) ; “ bilsamo de 
Pert,’ ‘“‘semillas del obispo,” ‘‘cedro chino” (Oaxaca); “ yaga-guienite”’ 
(Oaxaca, Zapotec, Reko) ; ‘ hoitziloxitl” (Nahuatl) ; “balsamo negro”; “ bal- 
samo de San Salvador.” 

This tree furnishes the balsam of Peru or “ balsamum Peruvianum ” of com- 
merece. The commercial article comes chiefly, if not wholly, from El Salvador. 
The balsam, which is obtained from the trunk of the tree, is a viscid, dark red- 
dish brown, fragrant liquid, with a warm, somewhat bitter taste; it burns 
readily. It is an official drug of the United States Pharmacopoeia, having 
stomachic and expectorant properties. It has been employed for chronic ¢ca- 
tarrh, asthma, phthisis, etc., and for rheumatism and venereal diseases, but at 
the present time it is little employed by American physicians. The balsam is 
much used in Europe in the manufacture of perfumery. 

In the collection of the balsam, the first step is the beating of a band around 
the trunk of the tree until the bark is thoroughly crushed, then cuts are made 
in the bark and fire is applied to the openings, whereupon the sap takes fire, but 
this is soon extinguished. The tree is then left for 15 days until the balsam 
begins to run, when it is collected on pieces of cotton thrust into the incisions. 
The juice is squeezed from these into jars of boiling water, upon which the bal- 
sam floats. The trees will produce one to two kilograms per week, but they are 
tapped only in the spring before the rainy season. The balsam is at first amber- 
colored but soon turns brown. It is obtained also from the fruit, this kind being 
of better quality and known as “ balsamo blanco.” By a papal bull issued by 
Pius IV in 1562, and by another by Pius V in 1571, the clergy were authorized to 
use the “ bilsamo negro” in the preparation of the chrism, and it was declared 
a sacrilege to injure or destroy the trees. The balsam is still widely used for 
this purpose. 

The tree was well known to the early inhabitants of Mexico, by whom it was 
much used in medicine. It was one of the trees cultivated in the royal garden 
of Mexico, having been brought from the tierra caliente. Jars of the balsam 
were a regular article of tribute to the emperor. The balsam attracted the 
attention of the early Spanish explorers and was forwarded by them to Europe. 
Here the most extravagant properties were ascribed to it, and it sold at prices 
ranging from twenty to two hundred dollars an ounce. In early days much of 
the balsam is said to have reached Spain by way of Peruvian ports; hence the 
derivation of the misleading name of ‘‘ balsam of Peru.” An infusion of the 
fruit in alcoholic liquors is employed locally as a stimulant, diuretic, and anthel- 
mintic, and as a lotion to remove freckles. 

The tree is described and figured by Hernindez’* in a chapter entitled “ De 
Hoitziloxitl, seu Arbore Balsami Indici.” He states that the Panucans called 
the tree “ chucte.” An inferior kind of balsam, he states, was obtained by boiling 
the twigs in water.

the upper surface, sericeous beneath; racemes few-flowered, the flowers white, 
tinged or dotted with purple; fruit white-sericeous, 2 or 3-seeded. 


2. Sophora tomentosa L. Sp. Pl. 373. 1753. 

Known in Mexico only from Clarion Island, Baja California. -Widely dis- 
_ tributed on seashores in the tropics of both hemispheres. 

Shrub, 1 to 3 meters high, leaves deciduous, the leaflets 15 to 21, oblong to 
orbicular, 2 to 4 cm. long, sericeous beneath, at least when young; flowers 
yellowish white, 2.5 cm. long; pods long and slender, strongly constricted 
between the seeds; seeds brown. ‘“ Tambalisa” (Cuba). 

The plant is reputed to have diuretic, sudorific, and purgative properties, 
and is used in the West Indies as a remedy for venereal diseases. The seeds 
are commonly believed to be poisonous, and they, like other parts of the plant, 
contain a poisonous alkaloid. It is said, however, that in Madagascar the pods 
are fed to cattle.

Coahuila to San Luis Potosi. Western Texas and southern New Mexico. 

Shrub or small tree, sometimes 12 meters high, with a trunk 20 cm. in 
diameter; leaves evergreen, the leaflets 7 to 11, 2.5 to 6 cm. long, lustrous on 
the upper surface, beneath sericeous, at least when young; flowers 2 to 3 cm. 
long, violet-blue, very fragrant; fruit hard and woody, sometimes 20 cm. long; 
seeds large, bright red; wood hard, close-grained, orange-red, with yellow 
sapwood, its specific gravity about 0.98. ‘“ Frijolillo” (Nuevo Leén, Texas) ; 
“colorin”’ (Coahuila, Nuevo Leén, Texas) ; “ frijolito” (Texas). 

The seeds contain a bitter poisonous alkaloid, sophorine, and one seed is 
said to be sufficient to cause death in a human being. The Indians of Texas 
and adjacent Mexico used small quantities of the powdered seeds to produce 
a sort of intoxication. Taken thus the seeds produce general excitement, de- 
lirium, and finally deep sleep lasting two or three days. Children have been 
poisoned fatally by eating the seeds. The wood is said to yield a yellow dye.

1. Ormosia mexicana Standl., sp. noy. 

Type from Zacuapan, Veracruz (Purpuws 6826; U. 8S. Nat. Herb. no. 566950). 

Leaves large, brown-tomentcse, finally glabrate, the petiolules stout, 7 mm. 
long; leaflets 18, oblong, oblanceolate-oblong, or ovate, 8 to 17 cm. long, 4.5 to 
5.5 cm. wide, obtuse or rounded at the more or less unequal base, obtuse or 
acutish at apex, thin, green and glabrate on the upper surface, minutely pilose 
beneath with yellow hairs; racemes 10 to 17 cm. long, paniculate, the branches 
densely brown-tomentulose, the bracts and bractlets linear or lanceolate, 7 mm. 
long or shorter, subpersistent; calyx 1 cm. long, brown-tomentulose, the lobes 
about as long as the tube, lance-oblong, acute or acuminate; petals tomentuilose 
outside, the standard short-clawed, 13 mm. long, 10 mm. wide; ovary densely 
brown-pilose, 3 or 4-ovulate. 

No species of this genus has been reported previously from Mexico, and only 
two are recorded from Central America, both from Panama. O. mezicana is 
clearly district from the Panaman species. It resembles somewhat Dussia 
martinicensis Krug & Urban, of the Lesser Antilles, but the leaflets are so differ- 
ent that it may scarcely be referred to that species. The flowers, too, are smaller 
than in the Martinique plant.

A number of herbaceous species occur in Mexico. Those listed here are more 
properly herbs than shrubs, but they are frequently suffrutescent. The seeds 
rattle about in the inflated fruit, giving the effect of a rattlebox, hence the 
generic name. The plants of the genus are of little economic importance, 
although some are of value for forage. Some species are cultivated in India 
for their fiber, which is of good quality.

This species was formerly widely cultivated in the warmer parts of America 
for the extraction of indigo, although an Old World species, J. tinctoria L., was 
often used also. The latter is the chief source of the Old World indigo. In the 
southeastern United States indigo was an important crop in the early part of 
the nineteenth century. In 1794 about 1,500,000 pounds were exported to 
Europe. In southern Mexico, also, it was an important article of export, in 
Yucatéin up to 1885 at least. The blue dye, for which indigo is chiefly valued, 
was finally largely replaced by coal-tar products, although much natural indigo 
is still used, having been found superior for some purposes to the artificial 
dyes. One of the chief reasons for the decline of indigo cultivation in America 
is the fact that the extraction and handling of the dye is very injurious to the 
health of those engaged in the work. The process of extraction of the coloring 


STANDLEY—TREES AND SHRUBS OF MEXICO. 441 


matter is simple; the dried plants are soaked in water, and the infusion drawn 
off; the indigo soon settles to the bottom of the liquid and is rolled into balls 
and dried. 

The use of this plant as a dye was known to the aboriginal inhabitants of 
Mexico. In Sonora the Indians use it for coloring palm leaves and other 
articles. In addition the plant has been much used in domestic medicine. The 
Aztees used the seeds for urinary diseases and for ulcers, the leaves as a poul- 
tice applied to the head to reduce fever, and the plant as a remedy for syphilis. 
Febrifuge, vulnerary, purgative, antispasmodic, diuretic, and stomachie prop- 
erties have been attributed to the plant, and it is a favorite local remedy for 
epilepsy. In Brazil it is one of the reputed remedies for snake bites, and in the 
United States indigo is often applied to the stings of bees and other insects. 
The powdered seeds or a decoction of the roots are said to be efficient in 
destroying vermin upon the human body.

This plant has long been known in Mexico because of the peculiar properties 
of the wood. An infusion of the heartwood in water has at first a golden- 
yellow color which soons deepens to orange. When held in a glass vial against 
a black background it exhibits a beautiful peacock-blue fluorescence. The wood 
was well known in Europe as early as the 16th century, where it was called 
“lignum nephriticum,’” because of its supposed duretic properties. It was 
first mentioned by Monardes (1565), and is mentioned by Hernandez under the 
name “coatl” or “coatli.” He also states that the name “ tlapalezpatli,”? 
or “blood-red medicine,” was used for the plant. Sahagtn writes of the plant 
as follows: ‘“ There is a wild tree called coatli from which they get the branches 

@ 10r making the baskets which they call wacales. It is a flexible wood, and if 
put in water the latter becomes blue. It is a remedy for urinary diseases.” 

The foliage of the tree is aromatic and the flowers are fragrant. In Mexico 
drinking troughs made from the wood are used for watering fowls, or a piece 
of the wood is put in their drinking water to ward off diseases. Palmer re- 
ports that in Sonora a decoction of the wood is given as a refreshing drink to 
fever patients. The wood is much used in some localities for kidney and 
bladder affections. It also gives a yellowish brown dye.

linear, hirsute. “ Enredadera” (Porto Rico). 


17. CRACCA L. Sp. Pl. 752. 1753. 


Low unarmed shrubs; leaves pinnate, the leaflets usually numerous but 
sometimes only 1 or 3, commonly with numerous close parallel lateral nerves; 
flowers small or large, racemose; fruit linear, flat, bivalvate. 

Many of the Mexican plants of this genus are probably to be classed as 
herbs rather than shrubs, although most of them are inclined to be suffrutescent, 
at least at the base. All the Mexican species except one which, so far as 
known, is always a herbaceous annual, are included in the present treatment. 
Most of the species have very tough stems, which are broken with difficulty. 
Cracca viginiana L., of the United States, a herbaceous species, was used by 
the Indians of the Southeastern States to poison fish. It is said also to have 
diaphoretie and powerful anthelmintic properties.

Adventive in Yucatfin and sometimes cultivated for ornament. Native prob- 
ably of the East Indies; adventive in tropical America. 

Nearly glabrous shrub or small tree, sometimes 4.5 meters high; leaflets 
about 3 em. long; flowers very large, white or pink, pendulous; fruit 30 to 35 
em. long. “Pico de flamingo” (Yucatin); “cobreque” (Nicaragua); “ ga- 
llito,” “‘ biculo,” or “‘ cresta de gallo” (Porto Rico). 

The wood is soft, weak, and light. From incisions in the stem there runs a 
pinkish white juice, which dries into vitreous tears of a violet tint. From these 
is obtained a gum from which two coloring principles have been separated—a 
red one, agathine, and a yellow one, xanthoagathine. The bitter bark is said to 
have tonic and febrifuge properties ; in India it has been employed as a remedy 
for smallpox. Diuretic and laxative properties are ascribed to the leaves. In 
southern Asia the flowers and green pods are eaten as a salad or pot herb, and 
the leaves and young shoots are gathered and fed to cattle. For an illustration

hairs; calyx 3 mm. long, densely brown-pilose, the lower lobes triangular, 
acuminate; petals glabrous, the standard 8 to 9 mm. long; fruit flat, 5.5 to 7 
em. long, 1.2 to 1.4 em. wide, obtuse at apex, gradually tapering to the base, 
densely pilose with minute appressed brown hairs. 

Also collected at Bafios del Carrizal, Veracruz, August, 1914, by C. A. Purpus 
(no. 6083). The Purpus collection is in fruit only and was distributed as 
“Acacia?” The only other Mexican species of the genus, L. robinioides, is 
represented in the National Herbarium by a single collection (Purpus 5891), 
from Misantla, Veracruz, which agrees well with the original description 
and plate. LL. robinioides differs from the present plant in its lack of 
pubescence, less numerous leaflets, and smaller flowers. The flowers of 
L. brunnescens appear to have been greenish yellow, although of course their 
eolor may have changed in drying; those of L. robinioides are purplish.

small or large; flowers in axillary racemes; fruit linear, compressed, bivalvate. 

In C. glandulosa as well as in other species the branches are often covered 
with a transparent, yellowish or brown gum or lac produced by insects. 
Palmer reports that in Sonora this is dissolved in water with sugar and used 
as a drink in colds and fevers, and that it is believed also to be a remedy for 
tuberculosis. It is sold in the drug shops as “goma Sonora” at about a

Often planted for hedges, and a favorite shade tree for cacao and coffee plan- 
tations; grown from Seeds or cuttings. The leaves are eaten by cattle but, like 
other parts of the plant, they are poisonous to rats, mice, and other rodents. 
The seeds or powdered bark mixed with rice, etc., are used in tropical America 
for poisoning rats and mice. The tree is said to have been introduced into the 
Philippines from Mexico at an early date. 

This tree was first described by Oviedo (Lib. VIII, Cap. XXX), who says that 
in order to protect the cacao “they plant between the trees other trees which 
the Indians call yaguaguyt and the Christians madera negra, which grow almost 
twice as large as the cacao trees and protect them from the sun, and they 
prune the branches to make them grow straight. These trees are of such a na- 
ture that they live much longer than the cacao trees and never decay ; it is one of 
the strongest woods known. The madera negra has very beautiful flowers, pink 
and white, in bunches, and they have a good odor; the fruit consists of pods

which contafn lentils, somewhat smaller than lupine seeds and very hard; they- 
never shed their leaves and are trees that the Indians value for making hedges 
about their lands, and for wood for their houses or huts, for they say that it 
never decays. I tore down a Sacrificial building in Nicaragua a quarter of a 
league or less outside the city of Le6én, in the square of the Cacique Mahomo- 
tompo, who served me; for to separate the people from the rites and sacrifices 
and diabolic ceremonies we took from them the temples which, in the language 
of Charotega, to which that town belongs, they call teyopa; that is to say, houses 
of prayer. And I had taken to Le6n the wooden posts, all of which were 
madera negra, and made a stable for my horses. When I asked the cacique and 
the old men who had made that temple, they said it was built many years 
before; so far as I could understand, it was a hundred years or more; the 
wood that had been two yards deep in the ground was still as green and fresh 
as if just cut, and the axes rebounded and were nicked in cutting it. I am 
often reminded by this wood of the Ark of the Covenant of the Old Testament, 
made of shittim wood, which was incorruptible, and of the same wood was made 
the altar of the Lord. I do not know whether this madera negra of Nicaragua is 
shittim wood; but I do know that the Indians hold it for a fact that it is im- 
perishable, unless burnt, and so they affirm.” Oviedo treats the tree in another 
ehapter (Lib. VIII, Cap. XXXVIII) under the name “ yagaguyt.”

Veracruz; reported from Yucatéin. West Indies, South America, Asia, and 
Africa. 

Scandent shrub with pinnate leaves; leaflets numerous, oblong, 1 to 1.5 em. 
long, bright green, very obtuse; flowers racemose, pink or purplish; fruit short, 
broad; seeds 4 to 6, scarlet, black about the hilum. “ Xocoac,” ‘ xoxoag” 
(Yuecatin, Maya); “peonia’” (Cuba); “ peronia,”’ “ peronilas” (Porto Rico) ; 
“ brujitos,” “ chochitos de Indio, ” “ pionias,” ‘ peronilla ” (Colombia). 

The English names are “bead-vine,” ‘“ wild licorice,” and ‘ crab’s-eyes.” 
Stems strong and used as cordage. The leaves and root have the flavor of 
licorice, and the latter is sometimes employed as a substitute for that article. 
The root is said to contain glycyrrhizin, the principle found in true licorice 
(Glycyrrhiza glabra L.). The leaves are sensitive to changes in light intensity ; 
they droop vertically during the night and rise to a horizontal position in the 
morning. Lunan states that the dried leaves were used in India as a substitute 
for tea. 

The plant is reported to have poisoned caitle in India, and the seeds are cer- 
tainly poisonous. They have been used in that country for criminal poisoning, 
but are said to be inert if swallowed whole. It is said that the poisonous pro- 
erties are destroyed by heat and that the seeds have been used for food in some 
countries, but this is perhaps erroneous. They contain abric acid and two pro- 
teid poisons, to one of which the name abrine has been given. They are known 
in commerce as “ jequirity seeds,’ and have been employed by European phy- 
sicians in treating diseases of the eye and skin. The seeds are very handsome 
and are strung into bracelets and necklaces. Because of their uniformity in size 
they were formerly used as weights by jewel merchants. The leaves are ap- 
plied externally to swellings in India and are chewed with sugar for coughs.

42. ERYTHRINA L. Sp. Pl. 706. 1753. 


{EFERENCE: Standley, The Mexican and Central American species of Hry- 
thrina, Contr. U. S. Nat. Herb. 20: 175-182. 1919. 

Trees or shrubs, rarely herbs, usually with spiny branches; leaves pinnately 
3-foliolate; flowers in axillary or terminal racemes, showy, red or reddish; 
standard petal large or elongate, the other petals small, the wings sometimes 
wanting; fruit stipitate, linear, bivalvate. 

The species ‘are very common in many parts of Mexico, and their properties 
are well known there, but in literature there has been great confusion con- 
cerning the specific names. The larger forms are often planted as hedges 
because of their showy flowers and well-armed branches. Most of the species, 
unfortunately, flower when devoid of leaves. The plants were used for 
hedges by the early inhabitants of Mexico, and they are sometimes planted 
now for coffee shade. Branches take root readily when placed in the ground. 
The wood is very soft and light and is used for corks, for carving small figures 
and images, and for various other purposes. The bark is said to yield a yellow 
dye. The succulent flowers are often cooked and eaten as a vegetable or 
prepared as a salad. 

The handsome seeds, usually of various shades of red, are strung as neck- 
laces, and also used by children in games. They were employed by the early 
Mexicans in a game. somewhat like dice, known as “patol.” It is of interest 
to find that this name is now employed by the Hopi and other Pueblo Indians 
for a stick-dice game. 

The seeds of one of the Mexican species have been studied by Altamirano, 
who found in them erythroidine, a powerful paralyzant of the motor system, 
erythroresin, an emetic, coralin, and erythric acid. The extract has been sug- 
gested as a substitute for curare. The poisonous properties of the seeds are 
well known in Mexico, and they are used to destroy noxious animals. They 
have been employed also as a hypnotic agent. Species of Hrythrina growing ~ 
in other regions are known to have poisonous seeds, as in the case of the Javan 
EB. lithosperma Blume, from whose seeds a tetanizing alkaloid, hypaphorine, 
has been extracted. 

The bark and stems have similar poisonous properties, and they are em- 
ployed in tropical America to stupefy fish. From the bark an alkaloid, ery- 
thrine, has been extracted, which has a powerful effect on the nervous system. 
In Brazil the bark is employed in small doses as a hypnotic, purgative, and 
diuretic. The roots are used in Mexico for their supposed sudorifie properties. 
The leaves are reputed emmenagogue, and a decoction of the flowers is used 
in treating chest affections. The juice of the stems is applied to scorpion 
stings. 

A large number of vernacular names are reported from Mexico, but in most 
cases the specific application is doubtful. The usual names for the seeds are — 
“colorin”’ and “ patol” (from the Nahuatl, patolli) ; for the flowers “ pitos.” 
The following names are listed in literature: “ Zompantli,’ “ zompancle,” 
“zompantle,”’ “ zumpantle,” “ tzompantli,’ “tzompantle” (from the Nahuatl 
tzon-pantli, ‘‘hair-banner™; also tzon-pan-cuahuitl. ‘“ hair-banner-tree’’); _

with the large red seeds, for which they employ the name “ chilacayote,” a name 
used also for the seeds of species of Marah or Afegarrhiza, of the family Cucur- 
bitaceae. Palmer reports that in Durango the seeds are used as a remedy for 
toothache, and the wood for carving figures of saints, etc.

Mexico and Veracruz to Chiapas and Yucatan; type from Veracruz. 

Shrub or tree, sometimes 9 meters high, with spiny branches; leaflets 7 to 22 
em, long, glabrous or nearly so; flowers red; fruit few Or many-seeded ; seeds 10 
to 12 mm. long, usually scarlet. ‘“ Colorin” (Puebla); “‘ chacmolché” (Yuca- 
tan, Maya) ; “pito” (Veracruz). 

This is probably the species for which the names ‘ chontal,” “ madre chontal,” 
“madre cacao,” and “madre brava” are used in Tabasco. It is probable also 
that EH. coralloides DC? is a synonym of this species, although possibly that is 
rather the proper name for EH. flabelliformis. De Candolle’s name was based 
upon one of Sessé and Mocifio’s drawings, but the tracing of the latter seen by 
the writer is too imperfect for definite identification. HH. americana has been 
reported from Mexico as EH. corallodendron L., a West Indian species with red 
and black seeds which is not known to occur in Mexico.

Cultivated in Mexico and sometimes escaping. Native country not certainly 
known, but perhaps tropical Asia; widely cultivated and naturalized in tropical 
regions. 

Erect shrub or herb, 1 to 3 meters high; leaves pinnately 3-foliolate, the leaf- 
lets ovate or oblong, 3 to 8 cm. long, acute, puberulent and gland-dotted beneath ; 
flowers large, yellow, often striped or spotted with red, in short racemes; fruit 


' oblong-linear, bivalvate, pilose; seeds small, gray or brownish. “ Frijol de 
palo” (Nicaragua, Panama, Costa Rica); “ frijolillo” (Costa Rica); “ gar- 
banzo falso”’ (Nicaragua); “ guandti” (Costa Rica, Porto Rico); ‘ gandul,” 


“gandures’”’ (Porto Rico) ; “ timolillo,” ‘‘ quinbolillo’’ (Costa Rica); ‘* chicha- 
rros,” “quinconcho” (Venezuela) ; “ frijol guandus”’ (Colombia). 

The English name “ pigeon-pea”’ is said to have been given because pigeons 
are fond of the seeds. The plant is extensively cultivated in some tropical re- 
gions for its edible seeds, and in India it is said to hold third rank among the 
leguminous plants cultivated for food. The seeds are eaten either ripe or green. 
When cultivated the plant is usually treated as an annual, but if not cut it 
becomes a truly woody shrub. It is often grown for forage, and in Madagascar 
the leaves have been utilized as food for silkworms. In Bengal the plant has 
been grown as a host plant for lac insects. The stems are used in Asia for roofs 
and baskets, and they have been burnt into charcoal for gunpowder. Diuretic, 
astringent, antidysenteric, detersive, laxative, and vulnerary properties are 
ascribed to the plant. With regard to the flowers there are two chief varieties, 
One with yellow petals, the other with the standard purplish outside.

1. Mucuna sloanei Fawe. & Rendle, Journ. Bot. Brit. & For. 55: 36. 1917. 

Michoacan and Guerrero to Veracruz and Oaxaca. Tropical America and west- 
ern Africa. 

Scandent shrub or herb; leaflets about 9 cm. long, silvery-sericeous beneath; 
flowers large, yellow; fruit 4 to 5 em. wide, densely covered with bristly hairs; 
seeds subglobose, dark brownish gray, 2.5 cm. in diameter. ‘“ Pica-pica” 
(Oaxaca, Veracruz) ; “ ojo de venado” (Guerrero, Veracruz, Oaxaca, Panama) ; 
“ojo de borrico”’ (Veracruz) ; “ ojo de buey ” (Oaxaca, Porto Rico) ; “ matos del 
monte,” ‘“‘ matos” (Porto Rico). 

The seeds were eaten by the Caribs of the West Indies, and were formerly used 
in Jamaica for the manufacture of buttons and snuff-boxes. In Mexico they are 
sometimes worn as amulets. They are said also to be purgative and diuretic. 
The leaves are reported to yield a black dye. The hairs of the pods cause intense 
irritation when in contact with the skin. Formerly these hairs, like those of 
M. pruriens, mixed with molasses, formed a mixture of wide usage, administered 
internally, for the destruction of intestinal parasites in man. The hairs are 
softened by soaking in molasses, and are said to have no injurious effect upon the 
lining of the alimentary canal. 

This is probably the plant reported from Mexico by Sessé and Mocifio* as 
Dolichos altissimus.

ruptly short-acuminate at apex, the terminal one broadly elliptic-oval or 
rounded-oval, rounded at the base, the lateral ones usually smaller, oblique, 
very unequal at base, the leaflets thin, hispidulous on the upper surface, be- 
neath densely silvery-sericeous with lustrous hairs; peduncles often 50 cm. 
long or longer, slender, the racemes dense, 2.5 to 6.5 em. long, the pedicels re- 
curved, 4 to 5 em. long; calyx about 12 mm. long and broad, densely sericeous,

As in other species, when the bark is cut it exudes a blood-red juice that 
soon solidifies and forms a red resin which is insipid and inodorous. It was 
formerly used in medicine under the name of ‘“ dragon’s-blood,” and large 
amounts were at one time sent to Spain from Cartagena, Colombia. ‘

This has been confused with J. piscipula (..) Hitche. (Erythrina piscipula 
gE Piscidia erythrina L.; Piscidia piscipula Sarg.), a species confined ap- 
parently to Jamaica, where it is known as “ dogwood.” The properties dis- 
cussed below are probably common to all or most of the species. 

The wood is very durable, especially in water, and takes a fine polish. It 
has been used for boat building, fuel, and charcoal. Robelo states that in 
Mexico there is a popular belief that the wood petrifies after many years, be- 
ginning at the heart. The dry bark, especially that of the root, has a strong 
and disagreeable odor of opium; it produces a burning sensation in the mouth. 
It contains substances (one of which has been named piscidin) which are 
narcotic and analgesic, and has been used as an anodyne in neuralgia, nervous 
insomnia, whooping cough, etc. The extract of the bark is sometimes employed 
in tropical America for relieving toothache, applied locally, and that of the 
Jamaican species to cure mange in dogs. The best-known use of the tree, 
however, is its employment for poisoning or stupefying fish, the bark and leaves 
being crushed and thrown into the water. It is said that the Caribs used the 
juice for poisoning their arrows, but this appears doubtful.

PREFACE. 


The third installment of the Trees and Shrubs of Mexico, by 
Mr. Paul C. Standley, Assistant Curator of the United States 
National Herbarium, treats the families Oxalidaceae to Turnera- 
ceae, both inclusive. Several of the largest and most important 
groups of Mexican trees are included, such as the Meliaceae, which 
contains the true mahoganies of the genus Swietenia; the Euphor- 
biaceae, or spurge family; the Malvaceae, or mallow family; and 
the Sterculiaceae, among whose representatives is the cacao, Theo- 
broma cacao, perhaps the most peportant economically of all the 
native Mexican trees. 

The accounts of the families Meliaceae and Polygalaceae have 
been furnished by Dr. S. F. Blake of the United States Department 
of Agriculture.

Strong-scented shrub, 1 to 3.5 meters high; leaves opposite, persistent, com- 
posed of 2 oblong to obovate leaflets, these oblique, united at base, 5 to 10 mm. 
long; flowers solitary, the petals yellow, 8 to 10 mm. long; fruit of 5 carpels, 
densely pilose with long hairs. Mostly generally known as ‘ gcbernadora;” 
“hediondilla”’ (Sonora, New Mexico) ; ‘“‘falsa aleaparra”’ (Sonora, San Luis 
Potosi, Ramirez); “ guamis” or ‘ huamis” (San Luis Potosi, Chihuahua) ; 
“hediondo”’ (California). 

The creosote bush is one of the most characteristic shrubs of the dry plains 
of northern Mexico, often covering wide areas to the exclusion of most other 
woody plants. The flower buds, pickled in vinegar, are said to be eaten like 
capers. The plant is much used in domestic medicine, especially for rheu- 
matism, a decoction of the leaves being employed for baths or fomentations. 
The decoction is said, also, to have remarkable antiseptic properties, and is 
applied to bruises and sores. It is taken. internally for gastric disturbances 
and for venereal diseases. A reddish brown lac is often deposited upon the 
branches by a small scale insect. This lac is used in some parts of Mexico for 
dyeing leather red, and the Coahuilla Indians of California employ it as cement. 
The same Indians use a decoction of the plant for intestinal complaints and for 
tuberculosis. The Pima Indians of Arizona drink a decoction of the leaves as 
as emetic, and apply the boiled leaves as poultices to wounds and sores.

Coahuila to Tamaulipas; type from Parras, Coahuila. Southwestern Texas. 
Shrub or small tree, sometimes 7 meters high, with a trunk 25 ecm. in 

diameter, the branches stout, crooked; leaves pinnate, persistent, the leaflets 

8 to 12, linear, 1.5 cm. long or shorter; flowers 1 to 2 cm. broad, sweet-scented, 

purple; wood hard, compact, taking a fine polish, the heartwood dark brown, 

the sapwood yellow, the specific gravity about 1.10. ‘“Guayacin” (Coahuila, 

Tamaulipas, Texas). 

The bark of the roots is sometimes made into balls and sold in the markets 
as a kind of ‘“ amole”’; it is valued for washing woolen goods, since it does not 
fade the colors, and is esteemed also as a disinfectant. A decoction of the wood 
or bark is employed in domestic medicine as a sudorifie and vascular stimulant, 
especially in rheumatism and venereal diseases; it is reputed to be used as an 
emmenagogue. The durable wood is used for fence posts and other purposes. 
Known in Texas as ‘ soap-bush.”’

Yucatin and probably in Tabasco; perhaps also in Veracruz. West Indies and

Tree, sometimes 10 meters high, the trunk short, the bark thin, pale or white; 
leaflets 4 to 10, 2 to 3.5 em. long, glabrous; petals 7 to 11 mm. long; fruit 
1.4 to 1.7 em. long; wood resinous, light yellow, becoming green on exposure, 
very hard, with a characteristic odor, the specific gravity about 1.15. 
“Guayacan.” 

This species has been reported from many other parts of Mexico, apparently 
because it has been confused with G. coulteri. The wood is used for railroad 
ties and other purposes. 

Both G. sanctum and G. officinale L., the latter a West Indian species, are 
official in the U. S. Pharmacopoeia. The extract of the wood, which is known 
as “lignum-vitae,” has stimulant and diaphoretic properties. It was intro- 
duced into Europe as early as 1508 by the Spaniards, who had learned that 
it was used by the Indians as a remedy for syphilis. It was long highly 
esteemed as a remedy for syphilitic affections, and for gout, rheumatism, 
scrofula, and cutaneous diseases, but it is now believed to have no distinct 
influence upon such diseases. The resin also is employed, being stimulant, 
alterative, diaphoretic, and in large doses purgative. The bark and wood 
contain saponin. 

One of the species of Guaiacum is illustrated by Hernandez and treated * 
at length in a chapter entitled ‘De Hoaxacan, seu Ligno Sancto.”

Sonora to Oaxaca; type collected between Rayén and Ures, Sonora. 

Shrub or small tree, 1 to 12 meters high, with crooked branches; leaflets 
6 to 10, 1 to 2.5 cm. long, glabrous or nearly so; flowers fragrant, the petals 
blue or violet, 1 to 1.5 cm. long; fruit about 1.5 ecm. long. Known throughout 
its range as “ guayacin;” “arbol santo” (Puebla, Ramirez); ‘palo santo” 
(Oaxaca, Jalisco) ; “ matlaquahuitl” (Nahuatl, Ramirez); “ yaga-na” (Oax- 
aca, Zapotec, Reko) ; “ yutnu-tandaa ” (Oaxaca, Mixtec, Reko). 

The plant was reported from Mexico by Mocifio and Sessé as G. afrum L. 
The wood is hard and resinous, strong and durable, and is good for firewood, 
being used sometimes for fuel in railroad engines. It is employed also for 
making articles in which great strength is required. The tree is believed to 
have essentially the same properties as G. sanctum. 

The writer has not seen type material of G. planchoni, which was described 
from Oaxaca, but other material: from that state differs in no way from 
G. coulteri, and the characters supposed to separate the two species seem not 
to hold in the material examined.

REFERENCE: P. Wilson, N. Amer. Fl. 25: 173-224. 1911. 

Aromatic trees or shrubs, often armed with spines, usually furnished with 
glands in bark, leaves, and fruit; leaves opposite or alternate, estipulate, 
simple or compound; flowers perfect or unisexual, large or small; calyx 
inferior, with 3 to 5 lobes or sepals; petals 3 to 5, usually imbricate, some- 
times united; stamens as many or twice as many as the petals; ovary of 1 
to 5 or more free or united carpels; styles free or connate; fruit a follicle, 
capsule, samara, drupe, or berry. 

No herbaceous plants of the family are natives of Mexico. The rue family 
includes the important tropical citrus fruits, of which the following, and 
perhaps some others, are cultivated in Mexico. Citrus medica L., the citron 
(“cidra,” ‘cedro limén,” “cidrero’), with large fruits containing scant 
pulp, the rind of which is candied and used in confectionery; C. limonia 
Osbeck, the lemon (‘“lim6én,”’ limén agrio,” “limonero”; ‘‘nimft,” Otomi; 
“tzapposh,” Mixe); C. aurantifolia (Christm.) Swingle,’ the lime (‘ lima,” 
“lima chica,’ “limén dulce,” ‘lima chicona”); C. aurantium L., the sour 
orange (“naranja agria”); C. sinesis Osbeck, the common or sweet orange 
(‘‘naranja,” ‘“naranja dulce”; ‘“ yaga-naraxo,’ Zapotec; “ tzaptzouk,” “ tzap- 
kiuk,” “ tzaptzuik,” Mixe; ‘“ nanxa,” ‘“ xidni,’ Otomi) ; C. grandis Osbeck, the 
grapefruit, pomelo, or shaddock (‘ toronja’’); Triphasia trifolia (Burm.) P. 
Wilson, the lime-berry (“ limoncito ”), a small tree, grown for ornament. Some 
of these trees have escaped from cultivation in the warmer parts of Mexico. 

The citrus fruits were introduced into Mexico by the Spaniards immedi- 
ately after the Conquest. Bernal Diaz del Castillo’ claims for himself the honor 
of introducing the orange into Mexico, in 1518, while he was with Grijalva’s 
expedition. His account is as follows: “As this country [in Tabasco, at the 
mouth of the Tonalé River] is infested by mosquitos, in order to avoid them 
I went to sleep in a large temple, near which I at this time sowed seven or 
eight seeds of oranges, which I had brought from Cuba. They grew very well, 
for the priests of the temple took care of them when they saw that they were 
uncommon plants. This I mention, because they were the first trees of the 
kind that ever grew in New Spain. After the conquest of Mexico, this proyv- 
ince being considered as offering the greatest advantages, was chosen by most 
of the principal persons amongst the conquerors, of which number I was one; 
and on my arrival there I went in search of, and found my young trees flour- 
ishing, and having transplanted them, they all did very well.”

but it is more closely related to C. edulis, of which it may be only a pubescent 
form.

1896. 

Sargentia pringlei S. Wats. Proc. Amer, Acad. 26: 134. 1891. 

Nuevo Leén, San Luis Potosi, and Durango; type from San José Pass, San 
Luis Potosi. 

Shrub or small tree, 3 to 5 meters high, with grayish bark; leaflets 2 or 3, 
obovate or elliptic, 3 to 9 cm. long, obtuse or acutish. glabrous or nearly so, 
entire; flowers greenish yellow; fruit subglobose or oval, 1.2 to 1.8 cm. broad; 
seeds 10 to 12 mm. long. 


+The genus was dedicated to Casimiro G6émez, of whom the authors write as 
follows: “ Casimiro Gémez, ad Cardonal ex tribu Ottcmitarum edito, viro sobrio 
ae temperanti, in gerendo bello, promto, sagaci animosissimo, ipsi, quod a luxu 
abhorrens, et se milites suos humili victu ac vestitu conservans ac. ducens, 
exigua Ottomitarum manu, innumerabilia ac gloriosissima pro patriae bono 
gesserit.”

4, Casimiroa watsonii Engler; P. Wilson, N. Amer. Fl. 25: 214. 1911. 

Known only from the type locality, near Guadalajara, Jalisco. 

Leaflets 3 or 4, elliptic to oblanceolate, 3 to 7.5 cm. long, entire or nearly 
so, glabrate; fruit sweet and edible, containing 1 or 2 seeds. 

It seems rather doubtful whether this is distinct from C. pringlei. 


5. Casimiroa edulis Llave & Lex. Nov. Veg. Descr. 2: 2. 1825. 

Sonora to Jalisco; often cultivated; reported from many other parts of 
Mexico, but probably because of confusion with C. sapota. Guatemala. 

Large or medium-sized tree, with broad dense crown; leaflets almost always 
5, elliptic, oval, or broadly ovate, bright green, nearly or quite glabrous, often 
lustrous; flowers white; fruit 8 to 10 cm. broad, yellowish, with sweet pulp; 
seeds usually 5, 1.8 to 2.3 cm. long. The following names are reported, but 
most of them probably belong equally or exclusively to C. sapota: “‘ Zapote 
blanco” (the most common name); “zapote;” ‘“chapote;”’ “ matasano 
(Oaxaca) ; “ cochiztzapotl”’ (Nahuatl, ‘“ sleepy-zapote”) ; “iztactzapotl” (Na- 
huatl; ‘“ white-zapote’’) ; “ ccaxmuttza ” (Otomi, Buelna). 

This species may have a wider range than is indicated, but all the Mexican 
“specimens seen by the writer come from the Pacific coast. It is not absolutely 
certain that this species, rather than C. sapota, is the one described by Llave 
and Lexarza, but their description seems to agree better with it. 

The white sapote (including also Casimiroa sapota) is a well-known tree in 
Mexico, but is little grown outside that country. It is cultivated in the West 
Indies and has been introduced into southern California. The fruit varies in 
size and quality. It somewhat resembles an apple, and the best varieties are as 
large as a good-sized orange. The tender yellowish skin is thin, like that of an 
apple; the pulp is soft and cream-colored, of delicate texture, with a pleasant 
sweet flavor. The fruit ripens in July and August. It is much eaten in Mexico 
and is commonly sold in the markets. 

The fruits are popularly believed to induce sleep if eaten in quantity, and to 
calm rheumatic pains. The bark, leaves, and especially the seeds are said to 
contain a glucoside, casimirosine, which has a hypnotic and sedative effect upon 
cerebral centers. A small dose, it is stated, produces, at the end of an hour, 
deep sleep which lasts four to six hours. This principle, obtained chiefly from 
the seeds, has been used by Mexican physicians. 

The white sapote is described by Hernindez,* who says: 

“The Cochitzapotl is a large irregular tree, with thin foliage of ternate 
leaves like those of the orange; the trunk is spattered with white spots; the 
flowers are yellow and medium-sized; the fruit, of the shape and size of a 
quince, is called by the Spaniards Zapote blanco; it is edible and of agreeable 
flavor, but it is not to be counted a wholesome food; the stone which it con- 
tains is a deadly poison. The bark of the tree is dry and somewhat sweet, 
with a certain bitterness; the leaves, crushed and applied to the nipples of the 
nurse, cure diarrhea in infants; the seeds, crushed and roasted, cure putrid 
ulcers and proud flesh, and by exciting suppuration produce new flesh and 
hasten healing; if eaten, the fruits induce drowsiness, whence the name. The 
tree grows in hot and cold regions.”

Glabrous tree or shrub, with reddish brown branches; leaves simple, the 
petioles stout, 5 to 8 mm. long, subterete, the blades lanceolate or oblong- 
lanceolate, 6 to 9.5 em. long, 1.3 to 2.5 cm. wide, rounded or obtuse at the base, 
gradually attenuate from the middle or lower to the acute or subobtuse apex, 
coriaceous, bright green, sublustrous above, the venation plane or prominulous, 
scarcely paler beneath, the costa slender but prominent, the other venation 
prominulous, conspicuously gland-dotted; flowers few, in small terminal or 
axillary racemes or panicles, the pedicels stout, 2 mm. long or shorter; calyx 
1.8 mm. broad, the lobes very obtuse; ovary smooth; fruit globose, about 8 mm. 
in diameter; seed globose, 7 mm. in diameter. 

Only one other species of the genus is known, S. perforatus Liebm. It differs 
from the present plant in having unifoliolate leaves, the leaflet being much larger’ 
and broader than the leaf of S. conzattii, and abruptly short-acuminate at the 
apex. The Veracruz plant, moreover, has longer petioles and axillary racemes. 
The flowers of S. conzattii are not known, and until they have been studied, 
the generic position of the plant must remain in doubt. It may be that it 
should be referred rather to Amyris.

Shrub or small tree, sometimes 7 meters high, with a trunk 20 em. in 
diameter, the whole plant with a disagreeable odor; bark thin, smooth or 
nearly so, dark gray, reddish brown on young branches; leaves alternate, 
digitately 3-foliolate, the leaflets very variable in shape and size, glabrous or 
pubescent ; flowers greenish white, cymose; fruit a samara, 1 to 2.5 em. long; 
wood hard, close-grained, yellowish brown, its specific gravity about 0.83. 
“Cola de zorrillo” (Chihuahua). 

In the United States, where the plant is known as “ hop-tree” and “ wafer- 
ash,” the fruit has been employed as a substitute for hops. The root has a 
bitter, pungent, and slightly acrid but not disagreeable taste and a somewhat 
aromatic odor. It contains the alkaloid berberine. It has been employed as 
a remedy for dyspepsia and as a mild tonie. 

Many segregates from this species have been published besides the Mexican 
ones cited above. The species exhibits a large amount of variation, but it 
Seems impossible to divide the specimens into groups by any constant 
character. Wilson, in the North American Flora, has recognized three species, 
but the key characters given for the species are obviously of little value. Of 
the Mexican segregates, P. pumila is the most distinct, because of its very 
small leaflets.

Known in the Bahamas as “ wild lime.” The young leaves are frequently 
tinged with bronze. A decoction of the leaves is used in domestic medicine; that 
of the bark is said to be sudorific and to act as an arterial and nervous stimu- 
lant. The leaves and bark have a pungent and acrid flavor, and have been used 
as aspice. The bark is said to give a yellow dye.

from Mirador, Veracruz. Based upon sterile specimens. 

ZANTHOXYLUM PENTANOME DC. Prodr. 1: 725. 1824. Described from Mexico. 
Referred doubtfully by Wilson to synonymy under Z. monophyllum (Lam.) P. 
Wilson. That, however, is not represented by herbarium specimens from 
Mexico. It is distinguished by 1-foliolate leaves. The name Z. pentanome 
has been much used in works relating to Mexican plants. Some species so 
named is reported to be a remedy for the ‘‘ vomito negro” and for venereal dis- 
eases. It is said to be known as “ palo mulato.” 


12. PILOCARPUS Vahl, Eclog. Amer. 1: 29. 1796. 


The leaves of P. jaborandi Holmes and P. microphyllus Stapf, of Brazil, are 
official in the U. S. Pharmacopoeia, and leaves of other species also are used. 
They contain two alkaloids, pilocarpine and jaborine, which are the most reli- 
able of diaphoretics. They are widely employed for the treatment of dropsy, 
pleurisy, rheumatism, Bright’s disease, and similar affections.

Icica heptaphylla Aubl. has been reported from Yucatfin, where it is said

the genus from that State. 


2. ELAPHRIUM Jacq. Enum. Pl. Carib. 3. 1760. 


Shrubs or trees; leaves deciduous, simple, pinnate, or bipinnate, the leaflets 
entire or crenate, sometimes lobate; flowers small, solitary or in axillary 
panicles; fruit a small 3-angled drupe, containing a single large seed. 

The species all have a strong and characteristic oder resulting from the oil 
contained in the plants. All or most of them yield a resin, known as “ copal,” 
which is used in various ways, especially in domestic medicine. It is employed 
particularly as a cement and for varnish, and is burned by the Indians as 
incense in the churches and during some of their pagan celebrations. The 
name copal, which is of Nahuatl origin, is now applied in commerce to resins 
which come from Africa, the East Indies, and South America, and, indeed, 
most of the commercial resins known as copal come from those regions. The 
following vernacular names are reported for plants of the genus whose specific 


determination is doubtful: ‘‘Tacamaca”; ‘ papelillo” (Durango); “ teco- 
maca;” “ copalquahuitl” (Nahuatl; applied to various species) ; “ suchicopal ” 
(Colima, Veracruz, Jalisco); ‘‘sochicopal’” (Colima, Veracruz); ‘“‘ copalxo- 
chitl” (Colima, Veracruz) ; “ teponaxtle,” ‘“ teponaxtli,” ‘‘ teponaztli;” “ ciru- 


jano”’ (Morelos). The species are so closely related that many of the ver- 
nacular names are doubtless applied to more than a single one.

Tree, sometimes 25 meters high, with a trunk a meter in diameter, but usually 
much smaller, the branches thick and spreading; bark reddish brown, smooth, 
peeling off in thin sheets; leaflets usually 5 or 7, 4 to 14 em. long, variable in 
shape, usually acuminate or cuspidate-acuminate, commonly more or less 
pubescent; flowers greenish or yellowish, sweet-scented; wood light brown, 
soft, weak, its specific gravity about 0.30. ‘‘ Palo mulato” (Tepic, Chiapas, 
Tabasco, Oaxaea, Veracruz); “quiote” (Sinaloa); “palo jiote” (Chiapas,

The branches take root easily when placed in the ground, and the tree is 
often planted for shade or to form hedges. The wood, which has a strong 
characteristic odor, is not very durable, but it is employed for fence posts and 
canoes, and is burned for charcoal. From the branches a brownish gum exudes, 
which is often used as a substitute for glue and as a cement for mending 
broken china and glass. The gum is known in Costa Rica as “ elequeme” and 
“tacamahaca.” The Caribs employed it for painting their canoes to preserve 
them from the attacks of worms. The tree is much used in domestic medicine, 
the gum and sometimes the leaves being the parts employed. Diaphoretic, 
purgative, diuretic, and expectorant properties are attributed to it, and it is

employed for dysentery, dropsy, venereal diseases, yellow fever, and other 
affections. 

In Florida the tree is known as “ gumbolimbo,” a name used also by the 
Jamaican negroes, an apparent corruption of “ goma elemi,” the name some- 
times given by the Spaniards to the gum.’ The fruit is eaten by birds and pigs.

The bark is used for tanning and dyeing, and has been exported for that 
purpose from Baja California. The Indians of Sonora are said to use the 
branches for basketry. An infusion of the bark or gum is a popular remedy 
for venereal diseases. 

It may be that more than one species should be recognized here, but the 
characters that have been cited as distinguishing the three species here com- 
bined do not hold for the material examined by the writer.

Sonora and Baja California to Morelos and Puebla; type from San Gregorio, 
Baja California. 

Shrub or small tree; bark yellow, peeling off in thin papery sheets; leaflets 
5 to 11, 1 to 3.5 em. long, acute to rounded at apex, entire or obscurely crenu- 


late, usually glabrous but sometimes sparsely pubescent beneath. ‘‘ Cuajiote 
verde” (Morelos) ; “torote” (Baja California, Sinaloa) ; “ chutama” (Sina- 
loa). 


The gum is applied to cure scorpion stings, insect bites, and other wounds. 
It is yellowish, brown, or almost black, odcrless, acrid, and bitter, and is 
reputed to have expectorant and drastic purgative properties. It is used also 
for mending broken dishes. The bark is employed for tanning hides. 

The species is a variable one, the leaves varying greatly upon the same 
plant. All the names listed above refer to very closely related forms, which 
it seems impossible to separate by any constant character. For an illustration 
of a tree see Contr. U. S. Nat. Herb. 16: pl. 115.

The copal or resin of this tree is reddish and burns readily. It is usually 
gathered in September and October from incisions in the trunk, the juice being 
collected on maguey leaves, hence the name of “ copal de penea.” Dissolved in 
turpentine the resin gives a transparent and very glossy varnish. The copal 
is used in Mexico as a substitute for gum elemi. It is employed in treating 
_uterine diseases and in making ointments, and smoke from it is inhaled as a 
remedy for headache.

panicled, pink or lilac, sweet-scented; sepals 5; petals 5; filaments united into

(Porto Rico); ‘Arbol de quitasol” (Cuba). 

The chinaberry (known also as china-tree, pride of India, and umbrella-tree) 
is much planted in Mexican parks and gardens. It grows very rapidly, but the 
trees do not last long and the branches are easily broken off. Both flowers and 
fruit are borne in great profusion, and the yellowish fruits hang on the tree a 
long time. The wood is soft and weak. The large seeds are sometimes used 
as beads, and oil has been extracted from them. 

The bark contains a bitter principle, mangrovin. The roots have a bitter, 
nauseous taste; they have been widely used as an anthelmintic but their effi- 
cacy is doubtful. The leaves are reported to have emetic properties, and they 
have been employed as a febrifuge and as a remedy for hysteria. The fruit 
is eaten by cattle, but it is generally reputed to be poisonous to human beings. 
The bark is said to be used in some regions for stupefying fish. In the southern 
United States there is a belief that if horses eat the fruits they will be pro- 
tected against attacks of bots. It is said also that the berries packed with 
dried fruit will prevent the attacks of insects and that if laid among clothes 
they will keep away moths. A decoction of the fruits sprinkled over growing 
plants is reported to guard them from injury by cutworms and other insects. 

The specific name azedarach is of Arabic origin. For an illustration of the 
chinaberry see Contr. U. S. Nat. Herb. 8: pl. 45.

The trees of this genus are well known under the name of mahogany, and 
they are highly valued for their handsome, hard, heavy wood, which is much 
used for making fine furniture and the interior finish of houses. It should be 
noted, however, that not all the mahogany of commerce is derived from species 
of Siietenia; indeed, some of it is obtained from trees which have no rela- 
tionship with the family Meliaceae.

560 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


The first species of the genus to be described was Swietenia mahagoni Jacq., 
a West Indian plant which is not known to occur in Mexico, although it has 
often been reported from the region. All the species are closely related and 
presumably have similar properties. 

A large amount of mahogany wood is exported from Mexico, especially from 
Yucatéin and other coastal states (that from Yucatén is probably S. macrophylla). 
The trees grow rapidly and sometimes form extensive pure stands. The wood 
is used locally for furniture, for canoes, and for various other purposes. 

A gum frequently exudes from the trunk. The bark is said to be bitter and 
to have astringent, tonic, and febrifuge properties. The juice of the young 
shoots has been employed in Cuba to heal wounds and to stop hemorrhages. 
The oil from the seeds (‘‘ pepitos de zopilote’’) was used by the Aztecs as a 
cosmetic, and is now sometimes used in making toilet soaps. 

The following names are or have been in use in Mexico for species of the 
genus: ‘“‘Caoba,” “ caobo” (Guerrero, Tabasco, Yucatén, Oaxaca; the word 
probably of Carib origin) ; “‘cébano” (Colima, Guerrero) ; “ zopilo-zontecoma- 
cuahuitl” (Nahuatl, “ buzzard-head-tree,” in allusion to the fact that the fruits 
with their curved stalks, when hanging on the trees resemble buzzard heads, as 
viewed from a short distance); ‘“ zopilote”; “ tzopilotl”; ‘“ zopilocuahuitl ” ; 
“zopilotl”; ‘“rosadillo” (Guerrero, Tabasco, Yucatén); “palo zopilote”’ 
(Oaxaca, Conzatti). 

One of the species of Swietenia is described by Hernandez’ in a chapter 
headed “ De Tzopilotlzonte Comatl, seu Capite Aurae.”

Michoacin, Oaxaca); ‘flor de venadillo” (Tepic); “‘caoba” (Chiapas) ; 
“gateado” (Oaxaca). 

The seeds are said to be very poisonous. The seeds of a Swietenia supposed 
to belong to this species are sold by Indian peddlers in Tepic and used to make 
a tea which is taken for pains in the chest. The wood of this species is not 
known to be exported in any quantity.

The species of Spanish cedar are widely distributed in Mexico. They are 
large treeS with light coarse soft wood, which is widely employed for making 
cigar boxes. The wood is distinctive in appearance and has a characteristic 
odor. Large amounts of it are exported from Mexico, chiefly for making cigar 
boxes, and it has been employed locally for canoes, shingles, interior finish of 
houses, doors, sugar casks, rafters, and other purposes. The trees grow rapidly 
_ and sometimes form pure stands. The root bark is very bitter and has been em- 
ployed for treating fevers and epilepsy. A decoction of the leaves is held in the 
mouth to relieve toothache. A resin which exudes from the trunk is used for 
affections of the chest. The seeds are reputed to have vermifuge properties. 

The usual name for these trees in Mexico is “ cedro.” The following additional 
names are reported, but it is impossible to decide to what species they belong: 
“ Kuché,” “kulché” (Yucatén, Maya) ; “ cedro colorado”? (Oaxaca, Veracruz) ; 
“cedro chino”; ‘cedro liso”; ‘“cedro macho” (Oaxaca); ‘cedro de la 
Habana”; “calicedra’”’; ‘“‘cedro fino” (Veracruz, Oaxaca); ‘“ cedro oloreso” 
(Oaxaca) ; “ cobano”’ (Oaxaca) ; “ cedro hembra.” 

Cedrela odorata L., a West Indian species, has been reported frequently from 
Mexico, but is not known to occur in the region. It is to this species that 
Oviedo (Lib. IX, Cap. VII) refers, in what is probably the first account of 
Spanish cedar: “‘In Hispaniola and other islands and on the mainland there 
are certain trees which, because they have a pleasant odor, the Christians call 
cedro; in truth I do not believe they are cedars, but because the wood has a 
better odor than that of other trees, our carpenters have given it this name. 
It is an easily worked wood, good for making chests and door and window trim- 
mings and for other purposes, and it is a wood not much attacked by worms; 
for this reason some say that it is never attacked by worms, but they are 
much mistaken, for it has often been proved that it does suffer in this respect 
like other woods; although to the tongue it seems more bitter than other woods, 
the taste of a worm and that of a man are not the same thing.”

Small recoguized B. oaracana and B. karwinskiana as distinet species, but 
the characters by which they are supposed to be distinguishable seem not to 
hold in the material examined by the writer. 

The plant is much cultivated in Mexico and Central America for its acid 
edible fruit. This is usually eaten raw, but is sometimes cooked, and is 
used also for preparing a beverage similar to lemonade. In some localities 
it has been fermented to produce an alcoholic drink. The wood, which is said 
to be reddish and to have a specific gravity of about 0.67, is employed in 
various ways. The bark is used for tanning and dyeing, and is said, in addi- 
tion, to yield a strong fiber. The plant is astringent, and various parts hav. 
been used in domestic medicine for fevers, colds, and snake bites.

*With the hope of finding in Bering Strait the expeditions under Parry 
and Franklin, the British Government in 1825 dispatched H. M. 8S. Blossom 
under the command of Capt. F. W. Beechey. This ship anchored at San 
Blas in Tepic in December, 1827, and remained there until February, 1828. 
During this time the naturalist, Lay, explored Tepic and adjoining regions, 
and made a collection of plants. Some of these came from Jalisco, and 
on the labels that name was written “ Talisco,’ a circumstance which has 
caused a derivative of the latter incorrect name to be used as a specific 
name for some of the new species described from the collections. Plants were 
eollected also at Acapuleo and Mazatlin. Some of the naval officers, par- 
ticularly Alexander Collie, assisted Lay in making the collections. The 
plants were reported upon by Hooker and Arnott.

Lucas. Many new species were published by Gray in his report upon the col- 
lection (Proc. Amer. Acad. 5: 153-178. 1861). A set of the plants is in the 
U. S. National Herbarium. 

*In honor of José Pavén, a member of the Spanish scientific commission

One of the largest genera of plants, represented in Mexico also by many 
herbaceous species. The genus is divided by some authors into several, but the 
present writer has preferred to consider the species as belonging to a single 
genus. 

Euphorbia splendens Bojer, the “ crown-of-thorns,’ a native of Madagascar, 
is often cultivated in Mexico, where it is known as “corona de Cristo.” It 
has somewhat climbing stems which are covered with long stout spines; the

Jalisco and Guanajuato to Oaxaca. 

Tree, 8 to 10 meters high, with smooth yellow bark; leaves 3 to 6 cm. long, 
1 to 4 cm. wide, glabrous above or nearly so, Gensely pubescent beneath; flow- 
ering branches usually leafless, forming a 4 or 5-rayed umbel; involucre 
densely tomentose; capsule glabrous. Generally known as “palo amarillo”; 
“palo colorado,’ ‘‘ palo de cuearacha”’ (Oaxaca, Reko). 

This tree is of some importance as a source of rubber. The latex is thin 
and yellowish white and does not coagulate readily. When dried it is a 
doughlike, dark yellow substance. By tapping, about a liter of the latex may 
be obtained from a tree. The greatest difficulty in development of the tree 
as a source of rubber is found in the separation of the rubber from the resin, 
the amount of the former being 18 to 20 per cent and of the latter 40 per cent. 
The resin is said to make an excellent varnish. A good drying oil, suitable 
for varnish, has been extracted from the seeds.’

Michoacin and Guanajuato; type from Lake Patzcuaro, Michoacan. 

Shrub of small tree, glabrous throughout, the branches densely leafly; leaves 
oblanceolate, often very narrowly so, acute or obtuse, pale green; involucres 
in broad leafy umbels, the bracts suborbicular, whitish or tinged with red, 
apiculate. ‘‘ Chupire,” “ chupiri,” “ chupireni” (Michoacin, Tarascan, “ that 
which burns”) ; “ tencuanete” or “tenquanete” (Ramirez). 

The seeds are said to contain 30 per cent of oil, which has purgative proper- 
ties similar to those of croton oil. The milky juice of the stems causes blisters 
upon the skin and painful inflamation. This species is said to yield a kind 
of rubber much inferior to that obtained from WH. fulva. The plant is 
discussed by Hernandez’ in a chapter entitled “ De Chupiri, seu Charapeti, 
aquam rubeo colore tingenti Arcano Venerei morbi.” He states that the 
inhabitants of Michoacan emp!oyed the plant as a remedy for venereal diseases 
and other affections.

Shrub or small tree, 1 to 8 meters high, the branches glabrous; leaves large, 
usually broadly ovate or panduriform, acuminate, long-petiolate, glabrous or 
sometimes pubescent beneath; bracts of the inflorescence large and leaflike, 
bright red; involucres yellow. “Flor de Pascua” (Michoacin, Guerrero, 
Veracruz, Hidalgo, ete., Central America, Cuba); ‘“ Santa Catarina,” “ flor

“bebeta”’ (Veracruz); ‘“ pastora” (Costa Rica); “pastores” (Nicaragua) ; 
“Pascuas” (Philippines). 

This plant, which is generally known as “ poinsettia,” is cultivated widely 
in tropical countries and also in hothouses in temperate regions. In the United 
States it is especially common in florists’ shops about Christmas time. The 
bright red floral leaves make the plant extremely showy. It grows readily 
from cuttings. 

The bark is said to contain a red coloring principle, and it is reported that 
the bracts yield a scarlet dye. In Mexico a decoction of the bracts is some- 
times taken by nursing women to increase the flow of milk, but the practice 
is said to be dangerous. The leaves are applied as poultices for erysipelas and 
various cutaneous affectations, and Grosourdy states that the milky juice was 
employed by the Indians to remove hair from the skin.

be linear; involucres puberulent, in small clusters along the stems; capsule 
glabrous. ‘“ Candelilla” (Zacatecas, San Luis Potosi, Coahuila, Durango, 
Nuevo Le6n). ; 

A kind of wax thickly covers the branches, and factories in Nuevo Leon 
and San Luis Potosi have engaged in the extraction of this substance. The 
plant frequently grows with the guayule (Parthenium argentatum A. Gray). 
To obtain the wax, the branches are boiled in water, whereupon it rises to 
the surface. It is grayish in the crude state but after refining becomes yellow 
and finally white. It is used (mixed with paraffin) for candles, which burn 
with a bright light and agreeable odor. It is said to be excellent for oint- 
ments and for soap making, and has been found suitable for phonograph 
records and as an insulating agent in electrical work. The wax has been used 
also in shoe polish, floor polish, and lubricants, and for waterproofing. The 
plant has purgative properties and is much used in Mexico as a remedy for 
venereal diseases.

Phyllanthus distichus Muell. Arg. in DC. Prodr. 157: 413. 1866. 

Specimens seen from Tamaulipas, Guerrero, and Oaxaca, but perhaps only 
cultivated in Mexico. Native of the East Indies but cultivated in most tropical 
regions, and sometimes naturalized. 

Shrub or small tree; leaves orbicular to oval-ovate, mostly 5 to 6 em. long, 
short-pointed, distichous upon slender branches, these resembling pinnate leaves; 
flowers pink, in lax panicles; fruit large and succulent, pale green; seed large, 
lobate. ‘“Ciruela cortefa” (Oaxaca): ‘“manzana estrella” (Tamaulipas) ; 
“ srosella”’ (Costa Rica, Nicaragua, Cuba); ‘‘ cerezo comtin,” ‘“ cerezo de la 
tierra’ (Porto Rico) ; * cerezo occidental” (Cuba). 

This plant is often cultivated in warm regions under the names “ Otaheite 
gooseberry,” ‘‘ West Indian gooseberry,” ‘star gooseberry,’ and ‘“ jimbling.” 
The fruit is nearly 2 cm. in diameter, with firm, acid, and astringent flesh. 
It is usally pickled or made into preserves. The root and seeds are said to 
have purgative and cathartic properties. The wood is described as rather 
hard and fine-grained, with a specific gravity of 0.57.

The bark is said to be similar in odor and flavor to cascarilla bark, for 
which it is sometimes substituted. It contains a bitter principle, copalchin, 
which is found also in other species of Croton. In commerce the bark is 
known as “copalchi” and “quina blanca,’ and it is employed as a tonic, 
especially in intermittent fevers. It was formerly exported to Europe for 
medicinal purposes, but is no longer used abroad. The leaves are closely 
covered with silvery or brownish hairs, but they are sometimes also short-pilose.

(in Chiapas 7?) it is the food plant of a red caterpillar which is eaten by the 
natives. The hairs of the leaves adhere to the hands and injure the eyes when 
introduced into the latter.

Common in cultivation in Mexico, and naturalized in some localities. Native 
probably of tropical Africa, but now widely dispersed in tropical regions. 

Essentially an annual plant, but often shrublike, and sometimes becoming 
treelike and 9 meters high or even larger, glabrous, glaucous; leaves aiternate, 
large, palmately lobate, the lobes acuminate, dentate; flowers monoecious, 
apetalous, large, racemose; fruit a large, smooth or echinate capsule. Com- 
monly known as ‘“higuerilla”; “palma christi” (Oaxaca); “ yaga-bilape,” 
* yaga-higo”’ (Oaxaca, Zapotec, Reko) ; “ yutnu-nduchidzaha” (Oaxaca, Mix-

The castor-bean is cultivated to some extent in Mexico for its seeds, which 
are an important source of oil. This (‘‘ aceite de castor”) is well known 
and much used in medicine because of its purgative properties. It is widely 
employed as a lubricant, and has been used for illuminating purposes, in the 
manufacture of soap, for the manufacture of the Turkey-red oil required in 
_the dyeing and printing of cotton goods, and for dressing tanned hides. In 
India and China silkworms are fed on the leaves, and the stems have been 
used for making paper. The ground seeds from which the oil has been ex- 
tracted afford a valuable fertilizer.

The Indians of Ecuador string the seeds on sticks and burn them like candles. 
The decoction of the. root has been used in the West Indies as a remedy for 
colic, and that of the leaves for venereal diseases, while the leaves are applied 
to the head in cases of fever to alleviate pain. The value of the scalded leaves, 
applied externally, as a powerful galactogogue has long been known. The 
castor-bean has been in use since ancient times, being known to the Egyptians 
at least 4,000 years ago, and it is mentioned by the early Greek writers. Most 
of the seeds of commerce are grown in India. During the European war their 
production upon a large scale was attempted in the southern United States, 
but with most unsatisfactory results.

leaves mostly 3-lobate, pubescent, cordate at base; bracts large and whitish. 
“Xmool-coh” (Yucatén, Maya, Seler; “ puma-foot,” the calyx lobes closing 
like claws after the capsule opens); “ortiga” (Nicaragua); “ ortiguilla ”’ 
(Costa Rica). 

In Costa Rica the leaves are rubbed upon the cheeks as a remedy for tooth- 
ache. 

Some of the Madagascar species of Dalechampia furnish a black dye, and 
are used by the natives to blacken their teeth.

-cimarrona’”’ (Porto Rico). 

The seeds are eaten by doves and domestic fowls. They contain much oil 
-and have drastic purgative and emetic properties. A decoction of the leaves 
is employed as a blood purifier and for venereal diseases, and is administered 
as an emetic for pains in the stomach. The root has some repute as an anti- 
-dote for snake bites and as a remedy for the poison of manchineel (Hippomane 
mancinella).

The leaves are said to be cooked sometimes as a vegetable. The yellow sap 
is used in Brazil in the treatment of wounds, and the roasted seeds for fevers 
and venereal diseases. The seeds are purgative like those of many other 
species.

dyeing, and has been exported for those purposes. It gives a dark red dye, 
but is said to be injurious to cloth. The juice has astringent properties and is 
used in domestic medicine for hardening the gums, for skin eruptions, sores, 
dysentery, hemorrhoids, and venereal diseases, to prepare a gargle for sore 
throat, as a wash to restore and give luster to the hair, and to remove stains 
from the teeth. The roots are chewed to relieve toothache. 

The species exhibits great variation in the form of the leaves, even upon 2 
single plant.

Rica) ; “ tartago”’ (Porto Rico) ; “ tempate” (Costa Rica, Nicaragua, El Salva- 
dor) ; “tempacte’”’ (Guatemala); “tapate” (Costa Rica). 

Known in the British West Indies as “ physic-nut.” Often cultivated in 
Mexico as a hedge plant, because the branches take root quickly when placed 
in the ground, and because the plant is not eaten by stock. Palmer reports 
that the plant gives a purple dye and is sometimes used for tanning. The 
wood is very soft and spongy. The seeds have an agreeable flavor and have 
been eaten by children, but sometimes with fatal results, for they are poison- 
ous. They contain from 25 to 40 per cent of inodorous oil which is easily 
extracted by pressure. This has been employed in some regions for illuminat- 
ing purposes, also for soap making, as a lubricant, and in paints. The leaves 
are said to be used in the Philippines for stupefying fish. In Costa Rica they 
are applied as poultices for eczema and other skin diseases. The seeds possess 
drastic purgative properties. 

The plant is desribed at length by Oviedo -(Lib. X, Cap. IV), who men- 
tions the purgative properties of the seeds, which were known to the Indians 
who, on this account, planted the trees about their houses. He relates how 
his own small children in the city of Santo Domingo in 1520 ate some of the 
seeds and narrowly escaped death. The plant is described and figured by 
Hernandez,* who says : “The Quauhayohuachtli is a tree of medium size, 
with large leaves like those of burdock, round and angled. The fruit, some- 
what like plums or nuts, has three pifiones contained in its cavities, in their 
form, size, and kernels much like the fruits of our pine, but very different 
in their properties. It is a powerful vomitive, and purges all kinds of humors. 
For chronic diseases the seeds are much used, in the quantity of five or seven; 
always an odd number; I do not know the reason for this injunction. They 
are accustomed to make their action milder by roasting them and soaking 
them for some time in water or wine. Their nature is hot and oily. The tree 
grows in hot places, such as Tepecuacuilco [Guerrero].” Sessé and Mocifio 
state that the roasted seeds were ground and mixed with chile and tomato 
to make a sauce or condiment known as “ pipian.” Humboldt and Bonpland 
report that the Indians ate the seeds after removing the embryo.

STANDLEY—TREES AND SHRUBS OF MEXICO. 641 


An interesting account is given by Urbina? of axi, axin, or aje, an oily 
yellowish substance which is produced by a scale insect of the same name upon 
the branches of Jatropha curcas, Spondias, and other trees. Urbina quotes from 
Llave, who says: 

“The Coccus axin was brought from Tlacotalpan in the State of Veracruz, 
and Dr. Schiede, a German physician, has told me that he has seen it also 
at Papantla. This animal lives on the bark of the plant called in the tierra 
caliente Pién (Jatropha curcas) and on that called Jobo (Spondias mombin). 

“We know that they cultivate these insects in Tlacotalpan, whence they 
have sent information regarding the conservation, propagation, and extraction 
of the Avi. The first is practiced by placing the insects, when they have 
reached their full development (in October or November), within corn husks 
filled with corn silk, which latter alone should come in contact with the in- 
sects. These bundles are stored in a place which is dry and free from ants 
or other insects which might injure them; and in the month of May or June, 
when the rains begin, they open the bundles at one end, and find within a 
white envelope like spider web; and then they bind the bundles to the trees 
destined for propagation, and in a short time the trees are covered with the 
new insects. The trees used are known by the vernacular names of Jobo and 
Pifién; and as soon as the insects find a place on the bark they remain fixed 
there until they are scraped off in order that the Ari may be extracted from 
them. This operation is practiced by separating the insects first from the 
dust which covers them; next they are put to boil in ordinary water until 
they disintegrate and the wax rises to the surface, whereupon they are strained 
in a piece of cloth in order to extract all the wax possible. This is placed 
in jars and left to stand 20 hours or more, when it is found to be slightly 
coagulated; then it is stirred until it forms small balls, which are washed 
and put over a slow fire to remove the moisture; afterward the wax is 
strained, and when cold it is in form fit for use. 

“Among other uses, we know that the natives of Tlacotalpan employ this 
wax, melted, for varnishing pieces of crockery; and if a certain degree of heat 
is applied, there is obtained a sort of jelly, which, if rubbed over paintings, 
gives a very brilliant varnish. 

“The culture of the Avin is a fact which confirms the favorable opinion 
which must be held of the ancient inhabitants of our country, for the domes- 
tication of plants and animals is always a proof of civilization.” 

Urbina quotes also from Herrera, who says: “The Aje has a consistency 
like butter; it is yellow, and has a peculiar odor similar to that of rancid 
butter. * * * The Indians used it for erysipelas and as a resolutive and 
vulnerary ; they employed it also for the cure of hernia, mixing it with hule 
{crude rubber], turpentine, and arrayin; it is used for various uterine af- 
fections. In the arts it is used as an excellent varnish for wood and metals, 
and it is employed by the natives to varnish jicaras.” 

“Axin” is produced in many parts of Mexico. It is well known in Yucatan, 
where the Maya name is “ni-in.” The varnish is said to be very durable, 
and is employed, among various uses, for varnishing guitars. Dondé states 
(according to Urbina, loc. cit.) : “It is probable that the ancient inhabitants 
of the country (Yucatén) employed this oil in painting their buildings, and 
for this reason there are still seen, after three centuries, their decora- 
tions, whose good state of preservation aroused the admiration of Mr. Stephens, 
when, in 1842, he visited our ruins.”

Cassava? is one of the valuable food plants of the world, and the most 
important one in many tropical regions, taking the place of corn and wheat. 
It is much cultivated in some parts of Mexico, especiaily in the Yucatin Penin- 
sula, and is said to have been introduced in preconquest times. The plants 
are grown from cuttings. Two well-marked varieties occur: One may be used 
without special treatment (‘ yuca dulce”) ; the other has very poisonous juice, 
the injurious principle of which is made harmless by heat. The poisonous 
properties have been attributed to hydrocyanic acid, but others claim that they 
are due to a peculiar principle, manihotoxine. Meal, starch, and cassava or 
tapioca are obtained from the roots. The first is prepared by peeling and grat- 
ing the root, expressing the juice, and drying and sifting the meal, which must 
also be heated in the case of the poisonous variety. Starch is obtained by pre- 
cipitation from an infusion of the grated roots. Tapioca is prepared by roast- 
ing the starch grains. The roots of the cassava plant also furnish a useful 
food for stock of all kinds. Cassaripe, the thickened gum obtained from the 
root of yuca agria, has antiseptic properties and is commonly used in Brazil for 
the preservation of meat. The Caribs prepared an intoxicating liquor from the 
roots. According to Barham, the fresh roots, when eaten, cause pain in the 
stomach, swelling of the abdomen, violent vomiting and purging, giddiness, 
chills, dimness of vision, and in a few hours death. 

The cassava plant is treated at great length by Oviedo (Lib. VII, Cap. II) as 
well as by most other early writers upon tropical American natural history. 
He describes the method of cultivation with considerable detail. The yuca 
dulce, he states, was not known in the islands. He asserts that the yuca agria 
is poisonous to all animals except cows, horses, and rats, and that “a small 
draught of the juice will kill an elephant or any other animal or man.” He 
does not claim to have had personal experience in the case of the elephant. 
“Tf this deadly juice is boiled two or three times, the Indians eat it, making 
soup of it, as a good pottage and tonic; but as it cools, they cease to eat it, 
for although it will not kill after it has been cooked, they say that it is difficult 
of digestion if eaten cold. If when the juice is expressed it is boiled down 
two-thirds and left to stand two or three days, it turns sweet, and this they 
use as a Sweet beverage, mixing it with other food; and after it is boiled and 
settled, the juice turns sour and is used like vinegar or sour wine. * * #* 
When there were many Indians in Hispaniola, if one of them wished to die, 
he ate the yuca roots, and after two or three days or less he died; but if 
he drank the fresh juice, he had no time for repentance, for his life ended 
then and there.” Oviedo states that six varieties of yuca, which he names, 
were grown in Hispaniola. According to the same author, “yuca” was the 


Haitian name for the plant, and the bread made from it was known as 
“ cacabi.”

The Mexican plant has nearly always been referred to H. crepitans L., but 
that species, which has a wide range in the West Indies and South America, 
and extends into Costa Rica, probably does not reach Mexico. Strangely enough, 
also, the plant has been reported in some Mexican publications as Strychnos 
ignatii, a Philippine plant of a distantly related family. Hura polyandra dif-

fers from H. crepitans in the structure of the stamens, but otherwise resembles 
it closely, and it-may be presumed that the two species have the same properties. 

The wood is light and soft, whitish, with brown stripes; the specific gravity 
is about 0.50. It is used for various purposes but not very extensively. In 
parts of Mexico the trunks have been employed for telegraph poles. The 
copious milky juice is poisonous in contact with the skin or if taken internally. 
On the west coast it is much used for poisoning fish. The most curious part 
of the tree is the large fruit, which resembles a small pumpkin. When ripe 
the fruit explodes with considerable violence, scattering the sections (which 
are arranged like those of an orange) with the inclosed seeds in every direc. 
tion. The seeds, which contain about 50 per cent of oil, have violent purgative 
properties, and are sometimes administered internally, but their use is danger- 
ous. They are used for poisoning coyotes and other animals. The juice of 
this and H. crepiians is said to have been used as a remedy for elephantiasis 
and leprosy. 

The English name usually applied is sandbox tree. This is derived from 
the fact that in early days the immature fruits were dried, and after the 
seeds had been removed the capsule was used as a container for the sand 
employed in drying or blotting ink. 

The tree is figured by Hernandez’ and described in a chapter headed “ De 
Quauhtlatlatzin,’? seu arbore Crepitanti II.”

The milky juice was employed formerly by the Indians for poisoning their 
arrows. The best-known part of the plant, however, is the fruit, which fur- 
nishes the famous “jumping beans” or “semillas brincadoras,”’ which are a 
commen article in curio shops of the Southwest. The following is a translation 
of the notes upon the subject published by Pax: 

“The jumping seeds have a curved outer side, with a rounded keel, and two 
flat sides. They are yellowish gray and show on the outside no opening or 
point of injury. If they are laid upon one of the flat sides, with a quick move- 
ment they turn upon the other. A longer time is demanded for the movement 
from the curved side to one of the fiat ones. Frequently the beans hop several 
millimeters in the air, and thus they may also move forward. 

“Soon after the first notice of these peculiar seeds it was conjectured that the 
cause of the movement must be a living occupant, which was verified by investi- 
gation. In the ‘jumping beans’ lives the whitish larva of a small butterfly 
belonging to the Tortricidae, named by Westwood as Carpocapsa saltitans. The 
insect occurs especially in the Mexican States of Sonora, Michoacfin, Guerrero, 
Puebla, and Veracruz. The larva consumes the contents of the ‘seed’ and 
covers the inner surface of the latter with a web. The French entomologist 
Lucas gives as an explanation of the jumping that the larva, which lacks much 
of filling the cavity, supports itself upon the web by its body-feet, then loosens 
its chest-feet and anterior body-feet, stretches itself out violently, and strikes 
upon the wall of its dwelling with its head. 

“With a warm temperature the intensity of the movement increases, al- 
though it is net brought to a halt by a lower temperature. Consequently the 
seeds occasionally brought to Europe retain their movement for some time. In 
Berlin the larvae survived for weeks in unheated rooms. Buchenau reports 
that Martens in 1871 brought jumping seeds to Europe * * *. He had left 
Mexico in the middle of June. There was no longer any food left in the seeds 
for the larvae. Nevertheless their violent movements continued until March of 
the following year. In April the larvae changed into chrysalises, and in May 
or June the butterflies emerged, for which they lifted up a circular lid Which

the larva earlier had cut out of the seed wall. Different investigations were 
made in order to discover the advantage derived by the insect from the move- 
ments. Some observers, among them Ascherson, surmise that the jumping of 
the seeds is a means of frightening seed-eating animals, an explanation which 
can scarcely be considered adequate. The ‘jumping beans’ are not produced 
in equal abundance every year. Many years none at all are found.” 

The “jumping beans” were not known in Europe until 1854, when some 
were sent to England by the British minister, and the determination of the 
plant which produced them was long unknown. In Mexico they are known 
to be derived in part from Sapium biloculare, and probably they are borne by 
plants of other related genera. In other countries also similarly affected 
fruits are found in nearly related plants: In Africa, Sapium ellipticum 
(Hochst.) Pax; in Brazil and Chile, species of Colliguaya. 

It may be that more than one species is represented here, but this seems very 
doubtful.

Tree, sometimes 18 meters high, with a trunk 90 cm. in diameter, but usually 
much smaller, the branches spreading, forming a rounded crown, the bark 
thick, scaly, gray or brown; leaves alternate, persistent, ovate or oval, 4 to 
10 cm. long, usually acute or short-pointed, crenulate-serrate, long-petiolate ; 
flowers monoecious, in stout spikes; fruit drupaceous, 2.5 to 3.5 cm. broad,

(Colombia, Venezuela); ‘“ pinipiniche,” ‘“ penipeniche” (Cuba); ‘“ hincha- 
huevos” (Mexico) ; ‘‘manzanillo de la costa” (Cuba). 

The usual HWnglish name is “ manchineel,” evidently a corruption of the 
Spanish ‘ manzanillo,”’ the latter name having been applied by the early 
Spanish explorers because of the resemblance of the fruit to an apple. The 
milky juice was used by the Caribs for poisoning their arrows. It is very 
poisonous if taken internally, and upon the skin produces severe inflamma- 
tion, but some people seem to be immune to the external effects of the juice. 
The smoke from the burning wood will cause inflammation of the eyes. The 
early explorers gave the most extravagant reports of the plant, stating that 
a person who rested beneath a tree would be blinded, or even die, but these 
statements were long ago proved to be erroneous. The wood has been em- 
ployed in the West Indies for cabinetwork and interior finish, but great care 
must be taken in working with it, even when dry, and in cutting the trees. 
The fruit was often mistaken by the early explorers for crabapples, and was 
sometimes eaten with fatal results. It is reported in the West Indies that the 
flesh of fish or crabs which eat the fruit is poisonous, but goats are said to 
eat the fallen fruit greedily without injurious results. The seeds and bark 
have been employed as a vermifuge, but their use is dangerous. A gum which 
exudes from the trunk has been used in Jamaica in the treatment of dropsy and 
venereal diseases. 

There are many references to manchineel in early American literature. 
Oviedo (Lib. IX, Cap. XII) writes of it as follows: 

“In these regions there are innumerable manzanillos, with which and other 
poisonous mixtures the Indians are accustomed to make that diabolic poison 
for their arrows. ‘These trees are usually low or spreading and some are 
more than 6 yards high; they have large tops full of leaves which resemble 
those of the pear. The trees are loaded with a fruit like apples, of good 
odor, as large as pears but round, or sometimes elongate, variegated with red, 
which gives them a pleasing appearance; but both they and the tree are poison- 
ous in their effects. In Hispaniola the Indians did not use the plant, but there 
is no man who sees the fruit, if he does not know it, who does not wish to 
feast upon it, for its appearance and odor are inviting. It has been proved many 
times that if men carelessly lie down to sleep under the trees, when they rise 
after a short nap there is great pain in the head and swelling of the eyes and 
cheeks. And if by chance the dew from the tree falls on the face, it is like fire, 
blistering and burning the skin wherever it touches; and if it falls in the 
eyes it blinds or burns them, and the sight is endangered. If the wood is 
burned no one can endure it long, for it causes much heaviness, and such head- 
ache that all stand away from it, be they men or any other animals.” Oviedo 
also cites one instunce of a man who ate five or six of the fruits and was 
- not injured thereby.

Richard Ligon, in one of the early English publications upon the West Indies, 
which is quaintly written and full of interesting information, gives the fol- 
lowing notes about the manchineel: 

“The people that have lived long there, say, ’ tis not wholsom to be under 
the shade of this tree. The fellers, as they cut them down, are very careful of 
their eyes; and those that have Cipers, put it over their faces; for if any 
of the sap fly into their eyes, they become blind for a month. * * * Yet, 
of this timber we make all, or the most part, of the Pots we cure our Sugar in; 
for, being sawed, and the boards dryed in the Sun, the poyson vapours out. 
* * * The fruit is like an apple John, and ’tis said to be one of those 
poysons, wherewith the Indian Caniballs envenome their arrows.”

California) ; “hierba mala” (Sonora); ‘ mago,” “magot” (Opata). 

This plant, like Sebastiania pavoniana, produces “ jumping beans” (see 
p. 648). The juice is poisonous as in other species, and in Baja California 
the finely chopped branches are thrown in water to stupefy fish. Exposure 
to smoke from the burning wood or sleeping in the shade of the tree is said 
to cause sore eyes. The juice is said to be used by the Opata Indians to 
poison their arrows, but according to McGee’ the evidence to this effect is not 
conclusive. 

This is probably the plant to which Clavigero es de la California, 
1789) makes reference, as follows: 

“Among the few plants of California there are some harmful ones, one of 
which is a certain shrub called by the Spuniards of that region palo de la 
flecha, for from it the Indians dwelling along the coast of Sonora obtain the 
terrible poison with which they poison their arrows, so as to cause mortal 
wounds. The Californians, although they are acquainted with the evil pro- 
perties of the plant, have never employed it.” 

The leaves are broader in Baja California specimens than in those from 
Sonora, but it is doubtful whether the peninsular plant differs essentially. For 
an illustration of the tree see Contr. U. S. Nat. Herb. 16: pl. 117, B.

“yaw-root.” The root is said to contain an alkaloid, stillingine. The fluid 
extract is used in large doses as an emetie and cathartie and in smaller ones as

The Old World box, Buxus sempervirens L., which is the best-known 
species, is often grown as a hedge plant. The plant is bitter and contains 
an alkaloid, buxine. A volatile oil distilled from the wood has been used in 
epilepsy, and a decoction of the wood has been employed in the treatment of 
rheumatism and secondary syphilis. A tincture of the wood was formerly 
employed as an antiperiodic. The leaves have been used in Europe as a sub- 
stitute for hops in brewing beer.

Sonora and Baja California. Southern California; type from San Diego. 

Shrub or small tree, 1 to 4.5 meters high, with dichotomous puberulent 
branches; leaves oblong to oval, 3 to 6 cm. long, nearly sessile, obtuse or rounded 
at apex, pale green, strigillose; flowers dioecious, the staminate in sessile or 
pedunculate clusters, the pistillate solitary, on recurved pedicels; sepals 5; 
pistillate calyx accrescent in fruit; capsule 3-valvate, about 8 cm. long; seeds 
by abortion usually one. “ Jojoba” (Sonora, Baja California). 

Known in California as “pignut,” ‘“ goatnut,” ‘“ sheepnut,” ‘ wild hazel,” 
and “ quinine plant.” Goats, sheep, and deer are fond of the fruit and leaves. 
The seeds have the flavor of chestnuts or hazelnuts, with a slight bitterness. 
The Indians ate them either raw or parched, and sometimes used them as a 
substitute for coffee. The seeds contain about 48 per cent of oil, which is used 
locally as a hair tonic. In southern California and northern Mexico the native 
people sometimes make a beverage from the seeds by roasting them and grind- 
ing them with the yolk of hard-boiled egg, then boiling the mass in water with 
sugar and milk, thus making a well-flavored and nourishing substitute for 
chocolate or coffee. 

The first reference to the plant is that of Clavigero (Historia de la Cali- 
fornia, 1789), whose account is as follows: “The jojoba is one of the most 
highly valued fruits of California. The plant which produces it is a shrub 
which grows on the dry slopes of the mountains, and its leaves are oblong,

notched, smooth, the size of those of the rese, of a rather grayish green color. 
The fruit is an oblong berry, the size of a filbert kernel, dark red outside, 
white within, and with an oily and not unpleasant flavor. This fruit has become 
noted because of its medicinal virtues, especially as a remedy for retention of 
the urine, resulting from phlegmonous concretions, as an aid to parturition, 
and as a cure for wounds. The oil obtained from it is an excellent remedy fer 
cancer, and since it has a good flavor, some of the people of California use it 
in salads like olive oil. This plant does not bear fruit every year, but only 
when there has fallen at least a heavy shower in the winter.”

South America; New Zealand; type from Ecuador. 

Slender shrub or small tree, 1 to 4 meters high; leaves opposite, subsessile, 
distichous, lance-oblong or oblong-ovate, 1 to 2 em. long, acute or acutish, 
puberulent or glabrate; flowers small, perfect, in long slender racemes, 
puberulent; sepals 5, imbricate, persistent; petals shorter than the sepals; 
stamens 10; fruit of 5 to 8 laterally compressed cocci, purplish. ‘* Tlalocopetate,” 
“ tlalocopetlatl ’’* (Nahuatl); “tisis” (Venezuela). 

The slender lateral branches with the crowded distichous leaves suggest 
a compound leaf. The plant contains a toxic principle, coriamyrtine, which 
in animals causes convulsions, increase in the respiratory movement and 
heart action, and finally death by asphyxiation and nervous exhaustion. Chil- 
dren have been poisoned by eating the fruit, and in Mexico the plant is used 
for poisoning dogs and other animals. In Ecuador the fruit is used to make 
ink, which has a beautiful violet color; it writes black, but after a few hours 
reddens, and the writing is said to be indelible. Other species, notably C. 
myrtifolia L. of the Mediterranean region, have similar properties. (. 
myrtifolia is rich in tannin and is employed for tanning skins, and the leaves 
yield a black dye.

Rica); “ciruela campechana” (Cuba); “jobillo,” ‘jobo francés” (Porto 


Rico) ; ‘ ciruela calentana’”’ (Colombia). 

The English name is “hog plum.” The tree is common in many parts of 
Mexico and is often planted, especially along fences. According to Merrill, it 
was introduced into the Philippines at an early date, and the name used there 
by the Tagalogs is ‘“ sirihuelas,” evidently a corruption of ‘‘ ciruela.” 

Usually the plant is only a shrub, with few long branches which frequently 
spread along the ground, but often it gets to be a small tree. It grows readily 
from cuttings. The wood is white or yellowish and when procurable in suffi- 
ciently large pieces may be used for interior finish and other purposes; it has 
been used in Brazil for paper pulp. _ The fruit varies greatly in size and qual- 
ity. The skin is rather thick, usually purplish, but often yellow. The flesh is 
acidulous and somewhat resinous. Large quantities of the fruit are eaten in 
Mexico, raw or cooked, and it is sometimes dried or made into sweetmeats. 
It is used also to make cooling beverages and sometimes for intoxicating 
liquors. There is a popular belief in Mexico that if eaten in too great quantity 
the fruit causes fevers. Cattle and pigs are very fond of the fruits and fatten 
upon them.? The fruit is reputed to have diuretic and antispasmodic prop- 
erties. 

The tree is treated by most of the early writers upon tropical America. 
Oviedo (Lib. VIII, Cap. XXI) treats of it under the names “ xocot,” ‘ ciruelo,” 
and “hobo.” “The wine made from the fruit,” he says, “is of fair quality 
and keeps a year; to me it appears better than the apple cider of Vizcaya. 
* * ¥* They also make very good vinegar of the ciruelas, and a good green 
sauce with them and avi.” Spondias purpurea is illustrated by Hernandez,* 
but without description, under the name “ mazaxochotli.” It is probably to 
this species also that Sahagtin refers, under the names “ macaxocotl” and 
“ atoyaxocotl.” The latter, he states, “is a large plum, sweet, and very good 
to eat, either raw or cooked. They make from it a drink wore intoxicating 
than pulque.”

hembra,” “jobo negro,” “ jobito,” “ciruela agria,’ “ciruela loca” (Cuba) ; 
““jocote de jobo” (Nicaragua) ; “palo de mulato”’ (Guatemala). 

This species is rather rare in Mexico but it is sometimes found in cultiva- 
tion; it may be that itis notnativethere. Spondias lutea is similar to S.mombin 
in its properties, but the fruit, although larger, is of inferior quality. The 
wood is described as soft but strong, grayish yellow, with a specific gravity 
of about 0.508. This species has doubtless been confused in Mexico with 
S. mombin. In the latter the fruit is either purple or yellow, while in S. lutea 
it is always yellow. 

Spondias lutea is treated at length by Oviedo (Lib. VIIII, Cap. II) under the 
name “hobo” (a word of Carib origin). “The young shoots of this tree,’ he 
states, ‘‘are good for Shaving the face, and for bathing the limbs, and they are 
of exquisite odor. The bark of the hobo tree, boiled and used to bathe the 
limbs, is astringent and relieves exhaustion due to traveling, and it is a 
healthful bath. And when in the country men seek a sleeping place they try 
to have it beneath this tree, for its shade keeps off the dew and never causes 
headache as many other trees do. * * * There may be mentioned another 
property of this tree which can be tested any day that one wishes or that 
necessity compels. When in traveling water can not be found and men are 
suffering from thirst, if trees of this sort are at hand they dig out the roots, 
and cutting a piece put one end in the mouth and raise the other, whereupon 
there comes forth enough water to satisfy any thirsty man. * * * This 
have I tried, as well as many others overcome by thirst, and it was learned 
from the Indians.”

The wood is said to be soft and purplish, with a strong odor, and to be 
used for making trays, small images, and other articles. Goats are fond of 
the leaves. The fruit, which is much eaten, is yellow and the flesh resinous, 
with acid flavor. The fruits are said to be known at Jojutla (Morelos) as 
“berracos” and “chupandias.” The large seeds are eaten by pigs, and they 
have been used locally (taken internally) as a remedy for leprosy. The bark 
is employed as a substitute for soap. ; 

The tree is figured by Hernindez’* and described in a chapter entitled 
“De Copalxochotl, seu arbore Gummosa pruniformi,.” He gives the Tarascan 
name as “pompoqua,” and reports that the plant was used in Michoacin for 
fevers, diarrhea, and dysentery.

The fruit has an acid flavor; on some trees it is pleasant to the taste but on 
others bitter (perhaps because immature). It is much eaten by the people of 
Baja California, and the stones are eaten by various animals. This is prob- 
bly the “ ciruelo” described by Clavigero (Historia de la California). For an

Yucatan, Campeche, Chiapas, and Oaxaca. Central America, West Indies, 
and South America; naturalized in the tropics of the Old World. 

Shrub or tree, 2.5 to 10 meters high; leaves obovate, petiolate, 9 to 15 em. 
long, rounded at apex, glabrous; flowers polygamo-dioecious, in large terminal 
panicles; calyx 5-parted; petals 5, linear-lanceolate, 7 to 8 mm. long, puberu- 
lent outside; fruit reniform, 2 to 2.5 em. long, borne on a large, thickened 
fleshy hypocarp. ‘“‘ Marafidn” (Yucatan, Oaxaca, Guerrero, Cuba, El Salvador,

zuela) ; “‘casoy’”’ (Philippines) ; ‘‘ cacahuil,” ‘“ cajuil” (Santo Domingo). 

Specimens obtained at Acapulco by Palmer were taken from a cultivated 
tree said to have been brought from Panama, and the plant is probably not 
native so far north. The English name for the tree is “ cashew” or “ cashew- 
nut,” and the French name is “acajou,” although the latter belongs more 
properly to the mahogany. 

The wood is close-grained, strong, and durable, the specific gravity being 
reported as 0.488. The flowers are green tinged with yellow or purple; they 
are sweet-scented and much frequented by bees. From the trunk there exudes 
a gum somewhat like gum arabic. This can be used for varnish, and in South 
America it is used for bookbinding in order to prevent the attacks of insects. 

‘The most important products of the tree are the fruit and receptacles, both 
of which are edible. The receptacle is pear-shaped, very fleshy, and yellow or 
reddish; it is astringent when green, but when ripe has a pleasantly acid 
flavor. In Mexico sweetmeats are sometimes made from the receptaeles, and 
in some parts of tropical America a kind of wine is made from them, and this 
after fermentation is distilled to obtain brandy.

The pericarp of the fruit proper contains an oil, eardol, which is acrid and 
caustic. This is driven off by heat, but the fumes which rise when the nuts are 
heated should not be allowed to reach the face or eyes. The roasted kernels 
are edible and have a pleasant milky flavor. The oil obtained from the nuts is 
applied in India to the floors and rafters of houses to preserve them from 
insects, but its use is dangerous. The ground kernels are sometimes used to 
flavor wine, and they are mixed with chocolate. 

A decoction of the bark has been employed as a remedy for diarrhea, for 
syphilitic swellings of the joints, and for diabetes. The oil from the pericarp 
is sometimes used for ulcers, persistent skin diseases, and leprosy, and as an 
application to remove warts and freckles, but because of its caustic properties 
it must be employed with great caution.’ 


5. MANGIFERA L. Sp. Pl. 200. 1753. 


1. Mangifera indica L. Sp. Pl. 200. 1753. 

Widely cultivated in the warmer portions of Mexico and sometimes growing 
without cultivation. Native of Asia; cultivated in all tropical countries. 

Tree, 10 to 15 meters high, with dense spreading crown; leaves petiolate, 
oblong-lanceolate, usually narrowly so, 10 to 20 cm. long, acute or cuspidate- 
acuminate, subcoriaceous, glabrous; flowers polygamous, whitish green, in large 
terminal panicles; sepals 5, 2.5 mm. long; petals 5, 5 mm. long; fertile stamens 
1 or 2, but 3 or 4 staminodia present; fruit a drupe, 3 to 4 cm. long or much 
larger. Generally known in Spanish-speaking countries as ‘* mango,” which 
is the English name also. 

The mango is one of the finest and most widely known of tropical fruits. 
It is said to have been introduced into Mexico at the beginning of the 19th 
century by Don Juan Antonio Gomez, a Spaniard living at Cérdoba.? It has 
been introduced into Florida and California in comparatively recent years. The 
mango makes a fine shade tree. The leaves are evergreen and when crushed 
they emit an ordor of turpentine. Those of young branches are usually tinged 
with red or purple. The trees are most commonly grown from seeds, but the 
better varieties are propagated by budding or grafting. 

The fruit is borne in the greatest profusion. Like most cultivated fruits, it 
varies greatly in size and quality. Some fruits weigh as much as 4 or 5 pounds, 
while others are no larger than plums. The shape varies from round to long 
and slender. Theskin is smooth, usually yellow or greenish but often tinged with 
red. The flesh is juicy and often has a delightful fragrance. In some varieties 
it has a strong flavor of turpentine, but in the better forms this is wholly lack- 
ing. The large seed is covered with long, tough fibers which extend into the 
flesh, but in the best varieties there is no fiber. The mango is most commonly 
used as a dessert fruit, but it is often cooked or made into preserves, and vari- 
ous beverages are made from it. The unripe fruit is often pickled in India and 
used in various sauces and condiments. Alcoholic liquors are sometimes pre- 
pared from the ripe fruit.* 

The wood is soft, brownish gray, with small spots and irregular lines of 
brown; its specific gravity is reported as 0.864. The seeds are said to possess 
anthelmintic and astringent properties. The bark also is astringent and is 
used locally for cutaneous diseases, chronic diarrhea, and fevers, while the gum

which exudes from the trunk is employed for the same purposes. The leaves 
and petioles are sometimes employed as brushes to cleanse the teeth and harden 
the gums, and even as a remedy for toothache. They are also used as a domes- 
tic remedy for affections of the chest and liver. For an illustration of the 
tree see Contr. U. S. Nat. Herb. 9: pl. 28. 


6. PISTACIA L. Sp. Pl. 1025. 1753. 


Pistacia vera L., of the Mediterranean region and western Asia, furnishes 
the pistachio nuts of commerce, and is extensively cultivated for that purpose. 
Pistachio nuts are the seeds or kernels of a dry drupe; they are green and have 
a peculiar flavor. P. lentiscus L., also of the Mediterranean region, yields mastic 
or mastiche, an official drug, which is a resinous exudate from the branches. It 
was formerly used for debility of the stomach and chronic diarrhea, but is now 
seldom given internally. The gum is employed to fill cavities in the teeth and 
is chewed to sweeten the breath, and varnish is prepared from it. The seeds 
yield an oil, and the leaves are used for tanning. P. terebinthus L. is the 
Cyprus turpentine tree. 


1. Pistacia mexicana H. B. K. Nov. Gen. & Sp. 7: 22. pl. 608. 1825. 

Coahuila and Tamaulipas to Guerrero and Chiapas; type from Chilpancingo, 
Guerrero. Western Texas; Guatemala. 

Shrub or tree, sometimes 6 meters high; leaves pinnate; leaflets 11 to 29, 
mostly alternate, oblique-oblong, 1 to 2 cm. long, acute or obtuse, nearly glab- 
rous; flowers small, dioecious, the pistillate ones in panicles 5 to 10 em. long; 
stamens usually 5; fruit a nearly dry drupe, oblique, slightly compressed, 3 
to 4 mm. long, purplish, glaucous. “ Ram6én” (Oaxaca); “lentiseco” (Nuevo 
Leén, Oaxaca; sometimes corrupted into “lantrisco”) ; “ yaga-guieguei’”’ (Oax- 
aca, Zapotec, Reko); “almaciga’” (the resin; Oaxaca). 

A resin exudes from the branches. The seeds are edible. ‘he specimens 
from northeastern Mexico have comparatively few leaflets, but some specimens 
from southern Mexico also have fewer than the typical form. ‘The form 
occurring in Texas and northeastern Mexico has been described recently as a 
new species, Pistacia texrana Swingle,? but it does not appear to the writer to 
deserve specific rank, since it is impossible to find any definite character by 
which it can be separated from typical P. mezicana. 


7%. SCHINUS L. Sp. Pl. 388. 1753. 
1. Schinus molle L. Sp. Pl. 388. 1753. 

Widely cultivated in Mexico and often growing without cultivation. Native 
of Peru and occurring elsewhere in South America. 

Tree, often 15 meters high or larger, with spreading crown and graceful 
drooping branches; leaves pinnate, the rachis marginate; leaflets 15 to 27, 
sessile, linear-lanceolate, acute, entire or nearly so; flowers small, yellowish 
white, in large panicles; petals 5, oblong; stamens 10; fruit drupaceous, 


globose, 5 mm. in diameter, rose-red. “Arbol del Per&,” “ Peré,” “ Pirul,” 
“molle,” “ pimienta de América” (various parts of Mexico) ; “ pelonquahuitl,” 
“copalastle” (fruit), ‘ copalquahuitl” (Nahuatl); “ttzacthunni,” “ ttzac- 


thimi,” “xaza” (Otomf, Buelna) ; “ pimiento,” “ muelle” (Colombia) ; “ pimi- 
ento de California” (Costa Rica) ; ‘ pimentero” (Chile). 

The pepper-tree (sometimes known also as “ California pepper-tree’”’) is 
very commonly planted as a shade tree in some parts of Mexico, especially in 
the Valley of Mexico, and is grown abundantly in southern California. The

tree ascends in the Andes to an altitude of 3,600 to 3,900 meters, but often 
occurs at much lower altitudes. It thrives in dry, sandy soil and can endure 
extended drought. The pepper-tree is said to have been introduced into Mexico 
by Don Antonio de Mendoza, the first viceroy, who sent the seeds from Peru. 
The specific name, molle, is the name by which the tree is known in western 
South America, and is derived from mulli, the old Peruvian name. 

Schinus molle is an excellent shade tree and a handsome one, remaining 
green throughout the year. The only objection to it is the fact that it harbors 
the black seale, which is a serious pest of citrus fruits. The wood is useful 
for various purposes and the bark for tanning skins. When fragments of 
the leaves are placed in water they execute quick jerking movements, due to 
the sudden discharge of the oil which they contain. The fruit contains a 
volatile oil, and has a flavor resembling that of a mixture of fennel and pepper. 
The seeds are sometimes used to adulterate pepper. In Mexico the fruit is 
ground and mixed with atole or other substances to form beverages. An 
intoxicating liquor, known as ‘“copalocle” or “ copalote” is obtained by fer- 
menting the fruit with pulque for one or two days. 

The pepper-tree is much used in local medicine. The powdered bark or its 
decoction is used as a remedy for swollen feet and as a purgative in domestic 
animals; it is reported to have astringent and balsamic properties. The gum 
which exudes from the trunk is bluish white, acrid, and bitter, and burns 
with a pleasant odor. It is often chewed as a chewing gum, and is said to 
have purgative and vulnerary properties. It is applied in Mexico in the form 
of an emulsion to the eyes to hinder the development of cataracts, and is 
used for genito-urinary and venereal diseases. The leaves are chewed to 
harden the gums and to heal ulcers of the mouth. The fruit has been used by 
Huropean physicians as a substitute for cubeb in the treatment of gonorrhoea, 
and a syrup prepared with it is used in Mexico for bronchitis.1 The tree is 
figured and described by Hernandez.”

9. COMOCLADIA L. Syst. Nat. ed. 10. 861. 1756. 


Trees or shrubs; leaves pinnate, the leaflets entire or irregularly dentate; 
flowers small, perfect or polygamous, in large axillary panicles; calyx usually 
3 or 4-parted; petals 3 or 4, deltoid-ovate, imbricate, spreading ; stamens 3 or 4; 
fruit drupaceous, the endocarp membranaceous. 

The juice of all the species is extremely poisonous, causing swelling of the 
parts affected and blisters upon the skin. That of some species has been used 
in the West Indies to cure ringworm and destroy warts, but its use is danger- 
ous. The species of Santo Domingo and their properties are described by 
Oviedo (Lib. IX, Cap. XX XIII), under the name “ guao.” ‘“ The Indian women

of Hispaniola,” he states, ““some of them who are willing to endure suffering 
to improve their appearance, since they are envious of the white women of 
Spain, take the roots of the guao and roast them carefully; and after they are 
well cooked and soft they rub them between their hands into a sort of paste; 
with this they anoint the face and neck and whatever part of the body they 
wish to whiten, and over this they place other ointments of herbs and comfort- 
ing juices, in order that the guao may not cook them alive, or that they may 
endure it; at the end of nine days they take off all this coating and wash, and 
they are now as changed and white as if they were born in Castile.”

It is probable that this is only a form of C. mollissima. The specimens of 
Comocladia at hand are mostly imperfect and quite inadequate for a thorough 
investigation of the relationships of the species. C. englerinana integra Loes., 
described from Guatemala, is known by the vernacular names “ chinil-té” and 
“pata de pava,” according to Seler. It is said to have handsome red wood. 

It is presumably one of the species of Comocladia which is described by 
Hernandez’ in his chapter entitled “ De Tetlatia, seu urenti arbore.”

wood hard, bright red, its specific gravity about 0.78. 

Sometimes known in California as ‘ lemonade-berry,” the fruit being used 
in the preparation of a cooling drink. The shrub forms dense thickets along 
coastal cliffs, but it grows inland also. The wood is used for fuel. The fruit 
is covered with an icy-appearing white substance, and has a pleasant flavor.

Rhus juglandifolia lindeniana Engl. in DC. Monogr. Phan. 4: 401. 1888. 

Veracruz, Oaxaca, and Chiapas. Central America to Venezuela and Peru; 
type from Colombia. i 

Tree or large shrub; leaflets 11 to 15, oblong or narrowly oblong, 7 to 15 
em. long, acute or cuspidate-acuminate, thin, pubescent or glabrous beneath; 
panicles 15 to 30 em. long; petals 2 to 3 mm. long, white; fruit about 8 mm.

Painful swelling and blistering of the skin is caused by contact with the 
plant. In Colombia the remedy employed for this is yuca starch, applied as a 
poultice to the parts affected. This is presumably the species reported by 
Sessé and Mocifio* as R. succedanea.

668 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


Low shrub or often a large woody vine, the stems clinging to trees by 
aerial roots; leaves deciduous, the 3 leaflets ovate or rhombic, 5 to 12 em. 
long, acute or acuminate, entire or irregularly dentate, pubescent or nearly 
glabrous; flowers green, in loose axillary panicles; fruit globose, 3 to 5 mm. 
in diameter. “Chechen” (Yucatin, Urbina); “hiedra ” (Sinaloa, Nuevo- 
Leén, Tamaulipas, Durango); “mala mujer” (Veracruz, Jalisco, San Luis 
Potosi); ‘“mexye” (Otomfi, Buelna); “ guardalagua” (Jalisco); “ hincha- 
huevos” (Veracruz) ; “ bemberecua ” (Michoacin, Tarascan) ; “ guau” (Ramt- 
rez); “hiedra mala” (Michoacin). The English name is “ poison ivy.” 

The species is a variable one, as might be expected from its wide range, and 
many segregates have been described, but it is impossible to determine their 
value until the group has been studied more critically than has been attempted 
heretofore. Both the dwarf and the scandent forms occur in Mexico. 

Poison ivy and its effects are well known throughout the range of the 
plant. All parts contain a nonvolatile oil, toxicodendrol, which is the active 
principle. Contact with the plant, or even one’s presence in its vicinity if it 
is covered with dew, produces painful swelling of the parts affected and an 
eruption of the skin. Some persons are very susceptible to the poisonous 
effects of the plant, while others are not affected at all. Those who are 
immune may, it is said, later become susceptible to it. Poisoning by the plant 
is painful and ofter dangerous, especially if the eyes are affected. Many 
remedies have been suggested, the most widely used, perhaps, being the 
application of an alcoholic solution of lead acetate. An extract of Grindelia 
(family Asteraceae) has been used successfully. In Mexico various remedies 
are reported, among them being a decoction of Heimia salicifolia and Lobelia 
fulgens (“ cresta de gallo’’).* 

The leaves were formerly official in the U. S. Pharmacopoeia. The juice 
is milky and turns black on exposure to air; upon linen it leaves an indelible 
stain. The plant has been used as a local irritant, but is no longer employed. 
A tincture is used by homeopathic practitioners as a remedy for rheumatism. 

The plant is mentioned by Clavigero (Historia de la California, 1789) under © 
the name “ hiedra maligna.”

Toxicodendron eximium Greene, Leaflets 1: 123. 1905.

Durango. 

Low shrub; leaflets rhombic, 4 to 9 cm. long, usually 3-lobed, the lobes again 
shallowly lobed, densely pubescent beneath or glabrate. ‘“ Hiedra” (Tamauli- 
pas). 

Perhaps only an extreme form of R. radicans. The type is densely pubes- 
cent, and a Tamaulipas specimen referred here is glabrate. The latter may 
represent a distinct species.

STANDLEY—TREES AND SHRUBS OF MEXICO. 669 


Sonora to Coahuila and Zacatecas. Western Texas to southern Arizona; 
type from Texas. 

Densely branched shrub, 1 to 2 meters high; leaflets 5 to 9, oblong to oval, 
rounded or obtuse at apex, mucronulate, pilose-strigose; rachis winged; in- 
florescence short and dense; petals 3 mm. long; fruit 6 to 7 mm. in diameter, 
red. ‘Correosa” (Coahuila, Durango, Texas); “‘agritos” (Chihuahua; 
fruit) ; ‘agrillo’”’ (Durango, Patoni). 

The fruit is edible, but it is sour and not very palatable. 


10. Rhus potentillaefolia Turcz. Bull. Soc. Nat. Moscou 31°: 469. 1858. 

Guerrero, Puebla, and Oaxaca; type from Oaxaca. 

Shrub or tree, 4.5 to 7.5 meters high; leaflets 13 to 21, oblong or narrowly 
oblong, 1.5 to 7 cm. long, deeply sinuate-lobed, rugose, densely pubescent on 
both surfaces, sessile; panicles much shorter than the leaves; petals 2 mm. 
long; fruit about 6 mm. in diameter, covered with very long soft reddish hairs. 

A plant of striking appearance, quite unlike any other species of the genus. 


11. Rhus glabra L. Sp. PI. 265. 1753. 

Mountains of Chihuahua. Widely distributed in the United States and 
Canada. : 

Shrub, or sometimes a tree 6 or 7 meters high, with smooth gray bark; 
leaflets 11 to 31, oblong or lance-oblong, 5 to 10 cm. long, acuminate, glabrous, 
pale beneath; flowers greenish, in dense terminal panicles; fruit covered with 
short red hairs. 

The white sumac is a handsome plant when loaded with ripe fruit. The 
leaves turn red in autumn. The bark and leaves are much used in the United 
States for tanning and dyeing, the leaves containing from 15 to 27 per cent of 
tannin. The roots also yield a yellow dye. The dried leaves were smoked by 
many of the Indians, alone or mixed with tobacco. The fruit is edible; it is 
acidulous and contains malic acid. The dried fruit is official in the U. S. 
Pharmacopoeia, its decoction or fluid extract being astringent and refrigerant 
and employed as a gargle for sore throat and for other purposes. The Pawnee 
Indians employed a decoction of the fruit for dysmenorrhoea and dysentery 
and a decoction of the roots for urinary troubles.

Schmaltzia ribifolia Greene, Leaflets 2: 156. 1911. 

Baja California to Chihuahua, Guanajuato, Hidalgo, and Colima. Western 
United States. 

Shrub, 1 to 2.5 meters high; leaflets mostly rhombic, 1.5 to 5 em. long, ir- 
regularly lobed and crenate, beneath densely pubescent or glabrate, the leaflets 
all essentially sessile; inflorescence short and dense; flowers greenish yellow; 
fruit 5 to 6 mm. in diameter, bright red. “Agrillo” (Durango); “ lemita” 
(New Mexico). The most common English name is ‘ skunkbush.” 

The species is an extremely variable one in pubescence and leaf form, and 
many segregates have been proposed. Few, if any, of these can be recognized 
as species, for the characters seem to intergrade in every direction. The most 
remarkable form of the species is that with simple leaves, which, in Mexico, is 
known only from Baja California. Specimens from that region were named 
Schmaltzia ribifolia Greene, but the form has received several earlier names. 
Simple and trifoliolate leaves are often found upon the same plant.

The wood was used by the Indians for bows. The dark red branches are a 
favorite article among many tribes for the manufacture of baskets. The fruit 
is sour and was eaten by the Indians, sometimes after having been preserved 


by drying. The fruit is often soaked in water with sugar to form a refreshing 
drink.

Sonora to Coahuila, San Luis Potosi, Zacatecas, and Durango; reported from 
Hidalgo; specimens from Puebla may belong here. Western Texas (type from 
New Braunfels) and southeastern New Mexico. 

Shrub or small tree, 1 to 6 meters high; leaflets 5 or 7, short-petiolulate, 
oblong-elliptic, oblong-ovate, ovate, or obovate, 2 to 5 em. long, glabrate, paler 
beneath; panicles axillary and terminal, usully shorter than the leaves; petals 
3.5 mm. long; fruit red or orange, 6 to 8 mm. in diameter. ‘“ Capulin” 
(Durango, Patoni); “lambrisco” (San Luis Potosi, Urbana); “ lantrisco” 
(Tamaulipas, Palmer; a corruption of ‘“ lentisco’’). 

The leaves were smoked by the Indians of Texas, either alone or mixed with 
tobacco. It is probably this species (it may be R. glabra) of which Berlandier 
writes,’ as follows: “The Ayuwmé abounded everywhere along the road, in the 
bottoms of the valleys, and along the beds of the arroyos; it is a small shrub 
6 to 12 feet high; its appearance is that of the plants of the family Terebin- 
thaceae. The inhabitants of Texas call it Aywmé, and the Comanches, who 
smoke it, know it under the name of Temaichia. The savages gather its leaves 
generally in the autumn, these being then red and very sharp; to preserve them 
they dry them by the fire or in the sun, and to smoke them they mix them with 
tobacco. The fruits are arranged in pyramidal racemes, rounded in form, red, 
oblong, and slightly acid. It is said that in Santa Fe, New Mexico, they make 
vinegar of the fruits of another species of Ayumé.”

A remarkable plant, the only species of the genus. It is leafless for most of 
the year. The wood is soft and porous and soon decays. The sap is milky 
and on exposure soon hardens into a gum or resin. Considerable quantities 
of the bark have been exported to Europe for use in tanning. For a more com-

Michoacan to Morelos, Puebla, and Oaxaca; type from Morelos. 

Tree, 4 to 6 meters high; leaflets sessile or nearly so, most of them broadly 
obovate, 2 to 7 cm. long, serrate or crenate above the middle or sometime also 
below, rounded to cuneate at base; fruit 2.5 to 5 cm, long, puberulent or glab-

The bark is astringent and contains tannin. Its decoction is used to harden 
the gums and to cure old wounds, and it is said to be employed also as a 
remedy for malaria. The bark yields a red dye. This plant has been listed 
in some Mexican works as Rajania subsarmata. 


4a. Amphipterygium adstringens simplicifolium Standl., subsp. nov. 

Oaxaca; type from Playa de Salina Cruz, Distrito de Tehuantepec (Conzatti 
3672; U. S. Nat. Herb. no. 989553). 

Leaves simple, petiolate, the blades oval or rounded-ovate, 4 to 6.5 cm. 
long, rounded or obtuse at apex, rounded or subcordate at base, coarsely 
crenate, glabrate above, densely short-pilose beneath ; fruit about 3 cm. long. 

This may be a distinct species, but it is more probably only a leaf form, 
analogous to the forms of certain species of Rhus and Hlaphrium. Two other 
specimens seen by the writer have simple leaves on some of the branches. 
The finding of a simple-leaved form in this genus is a matter of considerable 
interest, for it would seem to indicate a relationship with the Anacardiaceae 
and Burseraceae, groups to which the genus has been referred by most authors. 
Hemsley, however, considers the relationship of the family to be rather with 
the Juglandaceae.

Shrub or tree, 2 to 10 meters high, the trunk sometimes 30 cm. in diameter, 
the branches widely spreading; bark thin, pale brown, breaking up into large 
seales; leaves alternate, leathery, obovate or oblanceolate, 3 to 11 em. long, 
obtuse or acute, short-petiolate, entire, glabrous; flowers, perfect, white or 
pinkish, in lateral racemes; sepals 5; petals 5, about 3 mm. long, acute; 
stamens 5; fruit a 2-celled capsule, about 2.5 mm. in diameter; wood heavy 
and hard but weak, reddish brown, close-grained, its specific gravity about 0.68. 

The names used in the United States and the British West Indies are 
“leather-wood,” ‘ ironwood,” ‘‘burnwood,” ‘red titi,” and “‘ white titi.” This 
family has not been reported previously from Mexico or Central America. 
The cccurrence of the species in Oaxaca is rather remarkable, but it is prob- 
able that it will be found also in Veracruz. The Mexican plant is the form 
named by Michaux C. antillana. That is considered a distinct species by some 
authors, but Urban, correctly as it seems to the present writer, treats it as 
a synonym of C. racemiflora.

Tlex aquifolium J.., of Europe, is the true holly, so frequently mentioned in 
literature. The American holly is J. opaca Ait., a native of the eastern United 
States, whose branches are extensively used for Christmas greens. Most 
species of the genus have showy red fruit, and those with evergreen leaves have 
very handsome foliage. The leaves of I. vomitoria Ait., of the southeastern 
United States, contain caffeine. From them the Indians of the Gulf States pre- 
pared their “black drink,’ which had purgative, vomitive, diuretic, and some- 
what stimulant properties, and was used for ceremonial purification.

Ilex tolucana californica Loesener, Nov. Act. Acad. Caes. Leop. Carol. '78: 
302. 1901. 

Veracruz, Mexico, Hidalgo, and Oaxaca; Baja California; type from Toluca, 
Hidalgo. 

Glabrous shrub; leaves lanceolate or oblanceolate to oval, acute at base, 
obtuse at apex, serrulate or crenulate, lustrous; inflorescence glabrous; fruit 
globose, 4 to 6 mm. in diameter, with 4 nutlets, these 3-striate on the back. 
“Limoncillo ” (Hidalgo). 

The varieties described by Loesener differ only in leaf form. The writer has 
not seen sufficient material of the species to be able to judge of their systematic 
value. 

This species is closely related to I. paraguariensis St. Hil., the Paraguay 
tea or mate of Argentina, Paraguay, and Brazil, whose leaves are widely 
used in South America for the preparation of a beverage, which largely re- 
places tea and coffee in those regions. 

Tlez nitida (Vahl) Maxim. is reported from Veracruz by Loesener, but the 
writer has seen no specimens. It is closely related to J. tolucana, and the 
specimens reported may belong rather to the latter species. 


4. Ilex socorroensis T. 8S. Brandeg. Univ. Calif. Publ. Bot. 4: 90. 1910. 

Known only from Socorro Island, the type locality.

few appressed spinulose teeth or subentire; pistillate pedicels 5 to 9 mm. 
long ; flowers 6 or 7-parted ; fruit globose, 6 mm. in diameter; nutlets 6, strongly 
compressed, smooth. 

Some of the inflorescences are fasciculate, but the upper ones are solitary. 
Pringle’s 10004 from Trinidad is apparently of the same species. In it the 
pistillate pedicels are all solitary.

flowers unisexual, dioecious or polygamo-dioecious; calyx 4 or 5-lobed or parted; 
petals as many as the calyx lobes or none; stamens 4 to 12; fruit of 2 large 
united samaras. 

Some of the maples make excellent shade trees and they are often cultivated 
for this purpose. One Huropean species, A. pseudoplatanus L. (‘“‘ sicomoro”’), 
the sycamore maple, is said to be grown in Mexico. In most of the American 
species of the genus the sap is sweet, and by evaporation this yields maple 
sugar, an article well known to the Indians of North America, and still har- 
vested in large quantities in the United States each year.

ranging from Guatemala to Colombia. 


2. AESCULUS L. Sp. Pl. 344. 1753, 


The species which grow in the United States are known by the names “ liorse- 
chestnut ” and “ buckeye.” They are mostly large trees and are often planted 
for shade. Ramirez reports that Aesculus hippocastanum L. is planted in Mex- 
ico and is known as “ castafio de Indias.” The seeds of this species are bitter 
and poisonous. They contain much starch, and the bitter principle can be 
removed by alcohol or other agents and the starch extracted in an innocuous 
condition. The leaves contain a bitter principle, esculin. An extract of the 
wood is employed for dyeing silk black. The seeds of Aesculus californica Nutt. 
were used as food by the Indians of California, after having been roasted and 
the poisonous principle washed from the kernels with water. In the southern 
United States the seeds of various species have been used for stupefying fish, 
being first ground and mixed with flour, then thrown, into the water. The 
roots also have been used as a substitute for soap in washing woolen and cotton 
goods.

chapter entitled “De Quauhmecatl Zarsaparilla II. & III.” The people of 
“Yameguitlan”’ (Yauhuitlén, Oaxaca ?), he says, call the plant ‘“ Cozticuizti 
palancapatli,” and those of Michoacin ‘“ ychuanitzoz.” He states that its

The roots are said to have diuretic and sudorific properties. This species Is 
an extremely variable one and many attempts have been made to segregate 
the forms as species, but there seem to be no definite characters by which the 
forms can be recognized. Radlkofer considers C. corindwm a distinct species, 
but the characters by which he separates it from C. halicacabum are neither 
constant nor important. The writer is doubtful of the validity of C. tortuosum 
and C. spinosum.

tendril-bearing racemes; sepals 5, unequal; petals 4; stamens 8; fruit capsular, 
3-angled or 3-winged, 1 to 3-celled, 1 to 3-seeded. 

The crushed seeds of P. cupana Kunth and other South American species 
are official in the United States Pharmacopoeia under the name “ guarana.” 
They contain about 5 per cent of an alkaloid, guaranine, which is believed to 
be identical with caffeine. This is used in medicine for chronic diarrhea. 
The Indians of Brazil prepare from the seeds a beverage, which they use like 
coffee. They also prepare a fermented drink from the guarana seeds, cassava. 
and water. In Jamaica the juice of the leaves of some species was used as a 
remedy for heartburn, and the bruised leaves were applied to wounds. 

The crushed plants of various species of Pawllinia and of related genera are 
often thrown in streams to stupefy fish. It is probably to a plant of this 
family that Wells refers* in the following account, which is quoted here as 
an excellent description of the procedure followed in tropical America in catch- 
ing fish by thé aid of narcotic plants, a very common and widely spread 
practice: 

“A few days after my arrival at Lepaguare, I rode with Don Toribio to a 
place near the junction of the Almendarez and Guayape, where a chilpate 
fishing was to take place. On arriving at the river, we found a small party 
of natives collected on the banks of the smaller stream, engaged in spreading 
withes and a network of branches below a little series of falls or rapids 
above which the fish were known to exist in great quantities, especially the 
cuyamel, weighing often fifteen pounds when full grown. 

“The preparations completed, a few women entered the river about fifty 
yards above the rapids, bearing with them a common batea containing a decoc- 
tion of a vine pounded to a pulp, and known as the chilpate (possibly the 
Sapindus saponaria), and which may be gathered in any required quantity 
in the plains and along the banks of the streams. This possesses the singular 
quality, when mixed with the waters of a running stream, of stupefying the 
fish, causing them to float helplessly on the surface. When carried down the 
stream, they are taken by hand from the network below. The signal being 
given, this novel fishing apparatus was directed against the inhabitants of 
Almendarez. . 

“As the pale discoloration extended with the influence of the gentle cur- 
rent, my companion shouted to me to watch its effects. All eyes were riveted 
upon the water. In a few minutes a commotion was visible beneath the sur- 
face, and frequent flaps from the tails of sundry inebriated fish indicated 
the working of the drug. 

“The natives now ran below the falls to catch the victims who came floating 
down, some with fins or tails feebly wagging above the water, others ‘ half-seas 
over,’ ‘regularly laid out’ on their backs, and others as if under the effects of 
a systematic ‘ drunk,’ struggling against the liquor, and apparently determined 
to keep on their fins to the last gasp. There were fish of all sizes, from the 
cuyamel down to minnows. It was the most ludicrous, and, at the same time, 
strange scene I had witnessed in Olancho, and seemed an unpardonable corrup- 
tion of respectable fish from their original teetotal habits.”

for liver affections and the oil from the seeds as an anodyne liniment, while 
the plant has been used also as a remedy for gonorrhoea. Some of the Indians 
are said to have used the juice to poison their arrows, and it is reported that 
in the Antilles the negroes have made use of the seeds for criminal poisoning.

The flowers are sweet-scented. The seeds have a pleasant flavor, but they 
are poisonous. Havard states that an adult can eat one or two with impunity, 
but three or four produce giddiness and a sensation of heat and discomfort in 
the stomach. The seeds are sometimes used by boys as marbles. In Texas 
the plant is known as “ Texas buckeye,’ “ Spanish buckeye,” or ‘‘ Mexican 
buckeye.”

Baja California to Chihuahua, Nuevo Leén, Mexico, and Chiapas. Widely 
distributed in tropical regions. 

Shrub, 1 to 5 meters high; leaves linear to oblong-oblanceolate, 4 to 12 em. 
long, attenuate to the base, petiolate or sessile, acute to rounded at apex, pube- 
scent or glabrous beneath, viscid; flowers yellowish, unisexual, dioecious, in 
small lateral corymbs; calyx 3 to 5-lobed; petals none; stamens 5 to 8; fruit 
a 3-winged capsule, 3-celled, 1.5 to 2.5 cm. broad, each cell unusually 1-seeded. 
“ Ocotillo” (Guanajuato, Hidalgo) ; ‘ chapuliztoli”’ or “ chapulizle”’ (Nahuatl, 
from chapul-ichth—grasshopper-+fiber; it is said that the leaves are much 
eaten by grasshoppers) ; “ pirimu’ (Michoacan, Tarascan); ‘“ granadina” or 
“ grenadina ” (Baja California) ; “ jarilla” (Oaxaca, Morelos) ; “ hierba de la

(Colombia) ; ‘‘ chamiso”’ (Porto Rico, Argentina, Uruguay) ; “ gitarin” (Porto 
Rico) ; “ varal,” ‘““munditos”’ (Hidalgo). 

The species, as is to be expected from its wide range, is a variable one, 
especially in leaf form. The form with linear leaves, occurring in northern 
Mexico, is D. viscosa angustifolia (L. f.) Benth. The English name is “ switch- 
sorrel’; in the Bahamas the name “candlewood” is used. The leaves are 
bitter and in various regions are used for fevers, colic, gout, rheumatism, 
and venereal diseases. The bark is employed in the preparation of astringent 
baths and fomentations, and the decoction of the wood is reported to have 
febrifuge properties. The seeds are said to be edible. In Australia the 
fruits, known as ‘native hops,’ were formerly much used as a substitute for 
true hops (Humulus lupulus L.) in making yeast and beer. The wood is 
described as brown, close-grained, and hard, and in India it has been utilized 
for engraving, turning, tool handles, and walking sticks.

*The genus is named in honor of Cyrus G. Pringle (1838-1911), a native of 
Vermont, perhaps the best-known and most industrious of North American 
botanical collectors. It has been estimated that during his 35 years of field 
work he distributed to the herbaria of the world over 500,000 specimens, rep- 
resenting 20,000 species, 12 per cent of which were new to science. His work 
in Mexico began in 1882 and extended nearly to the time of his death, during 
which period he visited repeatedly nearly all States of the Republic. The 
specimens he prepared are noted for their superior quality, and are un- 
equaled, probably, by those of any other collector.

mous, in large terminal panicles; sepals and petals each 5; ovary 2-celled, 
only one of the cells developing ; fruit a 1-seeded berry, 1 to 1.5 cm. in diameter, 
with yellow translucent pulp; seed brown; wood light brown, dense, the specific 
gravity about 0.80. ‘“ Jaboncillo” (Nuevo Leon, San Luis Potosi, Durango,

(Veracruz, Seler) ; “ para-para” (Venezuela) ; “ palo jaboén” (Argentina). 

The fruits contain as much as 387 per cent of saponin, and when macerated 
in water they produce suds like soap. They are much used in Mexico and 
other regions for washing clothes. ‘The seeds are used for necklaces and 
rosaries, and they are said to have been used in England as buttons on 
waistcoats. The wood is of little use except for fuel. The fruit has been 
used as a febrifuge and for rheumatism and kidney diseases. It is said to 
be used also for stupefying fish. The fruits of some of the African species are 
edible, but their seeds are reputed poisonous. The tree is described by Oviedo 
(Lib. IX, Cap. V), who calls the seeds “‘ cuentas del xab6n.” 

Sapindus saponaria is a variable species, and some writers would divide the 
Mexican material into two or more species. To the present writer none of the 
forms appear to be of specific value. In the typical form of the species the 
rachis is broadly winged, but in the more common Mexican form the rachis is 
exalate or narrowly marginate. The latter is S. saponaria f. inaequalis (DC.)

*The genus was named for Wilhelm Friedrich yon Karwinski, a Bavarian, 
who spent many years in Brazil. In 1826 he was sent by a society at Diissel- 
dorf to Mexico to collect objects of natural history. He remained five years 
in Mexico, most of the time in Oaxaca, although he collected also in Hidalgo 
and probably in Mexico. He forwarded to Europe many living plants, espe- 
cially Cactaceae and Agaves. In 1840 he revisited Mexico on behalf of the 
Russian Government and obtained collections which were sent to St. Peters- 
burg. He died at Munich in 1855.

Actopan, Veracruz. Western Texas. 

Shrub or small tree, 1 to 8 meters high, the trunk sometimes 20 cm. in di- 
ameter; leaves oblong to oval or elliptic, 1 to 6.5 cm. long, rounded to acute at 
apex, paler beneath, with few or numerous pairs of nerves; umbels short- 
pedunculate, or some of them sessile; fruit 6 to 9 mm. long, blackish. “ Coyo- 


tillo” (Tamaulipas, Texas); “tullidora” (Nuevo Leén, Querétaro) ; “ tulli- 
dor” (Coahuila, Tamaulipas) ; “ capulincillo” (Nuevo Leon, Querétaro, Oax- 
aca); “ecapulincillo cimarrén” (Valley of Mexico, Querétaro); ‘“ capulin” 


(Coahuila, Tamaulipas); “palo negrito” (Sinaloa); “margarita” (Tepic, 
Jalisco, Colima, Sinaloa, Durango) ; “‘ cacachila china,” “ cacachila silvestre,” 
“ frutillo,” “negrito”’ (Sinaloa) ; ‘ cacachila”’ (Chihuahua) ; “ cachila” (Baja 
California) ; “ margarita del cerro” (Jalisco) ; “ tlaleapolin” (Nahuatl). 

The wood is said to be hard and strong. The fruit is sweet and edible, but 
the stones are harmful if swallowed. In people, especially children, paralysis, 
particularly of the lower limbs, is caused by eating stones, and similar effects 
are said to be produced in pigs and chickens. Palmer states that in Tamauli- 
pas children thus paralyzed are taken to a slaughter pen, and stomachs of 
freshly killed cattle are wrapped about the parts affected, an outer covering 
being employed to retain the warmth. There is a prevalent belief that this 
mode of treatment is quite successful. The seeds are oily, and they contain 
some principle which paralyzes the motor nerves. They are employed in 
Mexico as an anticonvulsive, particularly in the case of tetanus. An infusion 
or decoction of the leaves and roots is used locally for fevers, and Palmer 
states that the hot tea is held in the mouth as a remedy for toothache and 
neuralgia.” 

This plant is illustrated by Hernindez’? and described in a chapter entitled 
“De Cacatzin, seu parva Cacatl,” but little information is given concerning it. 
Clavigero (Historia de la California, 1789) also gives an account of the plant 
and of its harmful properties. 

The only Yucatin specimen seen by the writer is noteworthy in having 
sparsely pubescent flowers. The species is somewhat variable, but none of the 
forms appear worthy of specific rank. K. parvifolia, a form of the Pacific 
coast, has very small leaves, but the leaves vary too greatly in size through- 
out the range of the plant to permit the use of this as a specific character.

9. CEANOTHUS L. Sp. Pl. 195. 1753. 


Shrubs or small trees, often with spinose branchlets; leaves alternate or 
opposite, short-petiolate, entire or toothed, usually triplinerved; flowers per- 
fect, in cymes or umbels, these usually forming panicles or thyrses; petals 
white, pink, or blue; calyx 5-lobate; petals 5; stamens 5; fruit dry, 3-coccous, 
longitudinally dehiscent. 

Some of the species are showy when in flower. The blue-flowered ones are 
known on the Pacific coast of the United States as “ California lilac.” Ceano- 
thus americanus L., of the United States is known as “‘ New Jersey tea.’ The 
astringent roots contain over 6 per cent of tannin, and an alkaloid, ceanothine. 
They have been used in the treatment of syphilis, and are said to have purga- 
tive properties. The leaves were used by the Indians to make a beverage like 
tea, and during the Revolutionary War they were employed along the Atlantic 
coast as a substitute for Chinese tea. Gilmore’ states that the flavor of the 
beverage made from them “is something like that of Asiatic tea and is much 
better than that of the South American yerba maté.” The fresh flowers of 
some, and probably of all, of the species, when rubbed in water, gives a cleans- 
ing lather which is a good substitute for soap. 


Stipules persistent, the bases corky or spongy; leaves opposite, except in one

The numerous specimens examined are remarkably uniform in their char- 
acters, the only exception being a few which are referable to C. azureus parvi-

glabrate; panicles very large and broad, tomentose, the flowers whitish; fruit 
6 to 8 mm. in diameter. 
Sageretia salamensis Loesener,* described from Guatemala, is probably not 
separable from this species. 


11. RHAMNUS L. Sp. Pl. 193. 1753. 


Unarmed trees or shrubs; leaves opposite, petiolate, persistent or deciduous, 
pinnate-nerved. entire or toothed; flowers green, perfect or polygamo-dioecious, 
axillary, solitary, fasciculate, or umbellate; calyx 4 or 5-lobate; petals 4 or 5 
or none; stamens 4 or 5; fruit drupaceous, 2 to 4-celled, the nutlets osseous or 
vartilaginous. 

The species are known by the English name “ buckthorn.” R. cathartica L., 
of Europe, yields a green dye, and the fruit and bark have purgative properties. 
The dried bark of R. purshiana DC., of the western United States, is an official 
drug, known as “ cascara sagrada.’”’ The bark is yellow within, with a bitter 
and rather nauseous taste; its extract is used in medicine as a laxative. R. 
californica Eschsch. also has similar properties, and much of the drug of com- 
merce is probably derived from this species. i

It is said to give a conspicuous red tinge to the body of one who eats it in 
quantity. The bark has an agreeable odor and is rather bitter; it has tonic 
and slightly laxative, or in large doses cathartic, properties.

2. VITIS L. Sp. Pl. 202. 1753. 


Climbing shrubs; leaves long-petiolate, simple, toothed or lobed; flowers 
mostly dioecious or polygamo-dioecious, cymose-paniculate; petals caducous; 
ovary 2-celled; fruit a globose berry, pulpy, edible. 

The Mexican native grapes, like those of the United States, are difficult of 
separation, and their characters poorly marked. 

The cultivated grapes of Mexico are chiefly of the Old World type, being 
derived from Vitis vinifera L. The cultivated grapes of the eastern United 
States are derived from the native species. European grapes (“ vid,” the plant; 
“uva,” “parra,”’ the fruit; “bicholi,” ‘“yaga-bicholi,’ Zapotec) are said to 
have been introduced into Mexico about 1522, and their culture upon a large 
scale was begun at once, especially for the purpose of making wine. During 
at least a portion of the Spanish occupation, however, the local manufacture 
of wine was prohibited by the Spanish Government, for the protection of the 
wine industry of Spain. Clavigero states that vineyards were established in 
Baja California by the Jesuits, and that grapes were more successful there 
than any other fruit except figs. 

Oviedo relates that grapes were cultivated in Santo Domingo at the beginning 
of the sixteenth century, and he mentions particularly the vineyard of Diego 
Colén, which was destroyed through neglect. He refers to the wild grapes 
(Vitis tiliifolia) of Santo Domingo which, he says are good, “that is, for wild 
grapes,” and suggests that they might be improved by cultivation. Wine is 
occasionally made in Mexico from the wild grapes. The Indians of the United 
States sometimes dried the fruit for winter use, and in spring they tapped 
the larger vines to obtain the sap, which was used as a beverage. 

Wild grapes are mentioned by Hernéndez* in a chapter entitled “ De Ceual- 
chilehiltic, seu vite sylvestri, Lambruscave indigena.” He states that the name 
“ xocomecatl”’ also was applied to the plant.

The stems sometimes attain a diameter of 20 cm. From a section of the 
stem a considerable amount of water may be obtained, a fact of which ad- 
vantage is often taken by hunters or other persons in forests where the 
ordinary sources of water are wanting. The sap is reputed to have diuretic 
properties and a decoction of the leaves has been employed as a remedy for 
fevers. Descourtilz states that the leaves were applied as poultices for gout. 

It is probably this species to which the names Vitis indica and V. labrusca 
were applied by Sessé and Mociiio.*

ragua); “ubi” (Cuba); “caro,” “bejuco de caro” (Porto Rico, Santo 
Domingo). 


The species is a variable one, especially in leaf form and pubescence, and 
many segregates and varieties have been proposed. The inflorescence is often 
attacked by a smut, Mycosyringx cissi, and it is then greatly enlarged and modi- 
fied. This diseased form was made the type of a new genus, Spondylantha, by 
Presi. 

The tough stems are sometimes used as a substitute for cordage, and in 
Costa Rica for making baskets. When cut they yield a plentiful supply of 
watery sap. The leaves, when macerated in water, give a lather like that pro- 
duced by soap, and they are employed for washing clothes. They have a 
slightly acid flavor. Sometimes they. are applied to sores or inflammations, 
and in Mexico a decoction of the stems is used as a remedy for rheumatism. 
The fruit is said to yield a blue dye. 

Some of the Mexican specimens have been determined incorrectly as Ampe- 
lopsis cordata Michx. 

It is this species, apparently, which is figured by Hernaindez* as ‘“Tlacama- 
zateazqui y papan.” It is perhaps also the plant figured * and briefly described 
as “ yztae cacalic, seu Herba glutinosa, & candenti.” The decoction of the 
root of the latter, he states, was administered for diarrhea and as a diuretic, 
and used in baths to relieve pain of various sorts.

Baja California to Colima, Coahuila, Yucatan, and Oaxaca. Widely dis- 
tributed in tropical America. 

Plants glabrous or sparsely pubescent; leaves mostly trifoliolate, the leaflets 
2 to 9 em. long, usually broadly cuneate, coarsely dentate or lobate; cymes 
equaling or longer than the leaves; fruit purple or nearly black, 5 to 8 mm. 
long. ‘ Bolontobi” (Yucatin); ‘hierba del buey” (Chihuahua, Sonora, 
Ramirez); “uvilla” (Nicaragua). 

This has been reported from Yucatan as Vitis arborea L. Some of the Mex- 
ican specimens have been referred to C. incisa (Nutt.) Des Moul., a form 
which is doubtfully distinct from C. trifoliata. In Yucatan the mucilaginous 
leaves are applied as poultices for sores and cutaneous diseases. The leaves 
have an acid flavor and Barham states that in Jamaica they were eaten as a 
sauce with other food. Havard states that the large tubers borne upon the 
roots are very poisonous, causing violent vomiting and purging, and he reports 
that the leaves sometimes produce an eruption upon the skin, like that caused 
by poison ivy (Rhus radicans).

densely many-flowered, about 7 cm. broad, covered with sparse appressed 
whitish hairs; calyx 2 to 2.5 mm. long; corolla 3 mm. long. 

The material available is incomplete, but the very large flowers indicate that 
the plant is specifically distinct.

Palmer reports that in San Luis Potosi an infusion of the stems in “ aguar- 
diente’”’ is used as a remedy for stomach troubles. The species has been re- 
ported from Yucatan, where it is said to bear the Maya name “ xtab-canil.”

Sinaloa to Guerrero and Morelos; type from Acapulco, Guerrero. El Sal- 
vador. 

Large vine; leaves broadly cordate, 7 to 16 cm. long, acute, erose-dentate, 
angulate or often shallowly 3-lobate, densely ferruginous-tomentose beneath, at 
least when young; flowers dioecious, the staminate in very dense cymes about 
8 cm. broad, the branches densely tomentose; petals red, glabrous; fruit wine- 
colored, with a bloom, 12 to 25 mm. in diameter. ‘“ Uva” (Guerrero). 

In general appearance the plant is similar to some species of Vitis, but the 
large fruits and inflorescences are unlike those of any native Mexican Vitis. 
No information is available concerning the quality of the fruit; but its large 
size indicates that the plant might be a valuable one in cultivation.

acuminate, coarsely serrate, pale beneath, pilosulous when young but soon 
glabrate; cymes long-pedunculate, loose and open; seeds 2 or 3. 

This was described originally as having twice or thrice ternate leaves, an 
error arising from the fact that a branch was mistaken for the rachis of a leaf.

the peduncle winged with a large, foliaceous, partly adnate bract; sepals 
distinct ; fruit globose, nutlike, indehiscent, 1 or 2-seeded. 

The English names applied to species of Tilia are “linden” and “ basswood.” 
The trees are excellent shade trees and are often planted for this purpose. 
They are well adapted to street planting. The wood is light brown, soft, and 
light, with a specific gravity of 0.40 to 0.45. It is employed extensively for 
construction purposes, furniture, carriages, woodenware, and paper pulp. The 
tough fiber of the bark is sometimes utilized for cordage and rough mats. 
The sap is said to contain considerable sugar. The sweet-scented flowers yield 
an excellent quality of honey. The bark and leaves in water give a mucilagi- 
nous infusion. The flowers of 7. europaea L. are official in the German Pharma- 
copoeia. They contain a colorless fragrant volatile oil, and are employed as 
a remedy for hysteria and indigestion.

of paper was formerly made from the bark by beating it into thin sheets. The 
bark of young branches is tough and is often used as a substitute for cordage, 
or sometimes coarse rope and twine is made from it. The pulverized bark, or 
a decoction of it, is sometimes applied to sores.

7. TRIUMFETTA L. Sp. Pl. 444. 1753. 


Shrubs or sometimes herbs, with stellate pubescence; leaves often 3 or 5- 
lobate; flowers small or large, yellow, axillary or opposite the leaves, fasciculate- 
cymulose; sepals 5, appendaged at apex; petals 5, rarely absent; stamens 10 
to many; fruit subglobose, 2 to 5-celled, indehiscent or separating into 2 to 
5 cocci, covered with short or long spines, each of these uncinate at apex. 

The fruits adhere readily to cothing and other objects by their hooked 
spines. The inner bark of all species yields a strong fiber, resembling jute, 
which is suitable for the manufacture of cordage. 

The plants are said to have received the name “ paroquet-bur” in Jamaica, 
because parokets feed on the ripe fruit. The names “ jonote,” “ cajete” 
(Chiapas), and “ giiizapol de borrego” (Jalisco) are reported for Mexican 
plants of the genus, whose specific identity is uncertain.

Slender shrub, 1.5 to 3 meters high; leaves long-petiolate, ovate or rhombic, 
often trilobate, dentate, acute or acuminate, finely stellate-pubescent; sepals 
3 to 4 mm. long, densely tomentose; fruit (including spines) 6 to 8 mm. in 
diameter, stellate-pubescent, the spines slender. ‘‘ Mozote de caballo” (Costa 
Rica, Nicaragua) ; “ pega-pega”’ (Panama); “ cadillo” (Porto Rico); “ mata 
de negro” (Santo Domingo). 

The bark furnishes a fine and strong fiber. The leaves and bark contain a 
sweet, slightly astringent mucilage, and an infusion is used in Costa Rica as 
a remedy for colds. The plant is used also to purify or clarify syrup, in mak- 
ing native sugar.

(Cuba) ; “ escobilla amarilla” (Guatemala). 

Like the other species, this plant has tough fiber, which has been used for 
making rope, coarse cloth, and, in Brazil, paper. The roots are mucilaginous 
and astringent, and they are said to have diuretic properties. Locally they are 
administered for venereal diseases and for liver and kidney affections.

95. MALVACEAE. Mallow Family. 


Shrubs or trees, or more often herbs, the pubescence usually of stellate 
hairs; leaves alternate, commonly palmate-nerved, simple or compound, stipu- 
late; flowers axillary, racemose, or paniculate, usually perfect, the calyx often 
subtended by bractlets; sepals 5, more or less united; petals 5; stamens 
numerous, united to form a column; fruit usually dry, composed of several 
carpels, these verticillate about an axis, dehiscent or indehiscent, or the fruit

? Abutilon floribundwn Schlecht. Linnaea 11: 366. 1837. 

Sonora to Tamaulipas, Yucatan, and Guerrero. Cuba; Nicaragua. 

Stems herbaceous or suffrutescent, 1 to 2.5 meters high, obtusely trigonous, 
minutely tomentulose; leaves narrowly or broadly cordate, 4 to 15 cm. long, 
long-acuminate, crenate or subentire, grayish and minutely stellate-velutinous 
on both surfaces; calyx lobes ovate, acuminate; petals yellow, 5 mm. long; 
earpels 6 to 8 mm. long. ‘“ Amantillo” (Jalisco, Oliva) ; “ sacxin” (Yucatan, 
Dondé) ; “ tronador” (Colima). 

Palmer reports that in Colima the fiber extracted from the stems is utilized 
in making rope, hammocks, and nets. The stems are buried in mud for three 
or four days, then washed, and the bark (which contains the fiber) stripped 
from the stems by hand.

Abutilon terense Torr. & Gray, Fl. N. Amer. 1: 231. 1838. 

Baja California and Sonora to Nuevo Leén, San Luis Potosi, and Sinaloa. 
Hawaii. 

Shrub, 2.5 meters high or less, the stems minutely tomentose; leaves broadly 
cordate, 1.5 to 6 cm. long, obtuse to acuminate, crenate or dentate, finely 
grayish-tomentose; sepals broadly ovate, mucronate; petals yellow or orange, 
often purple at base, 6 to 9 mm. long; carpels 6 to 7 mm. long, minutely 
tomentose. “ Pelotazo chico” (Sinaloa). 

This, like A. trisulcatum, is a source of fiber. A. racemosum Schlecht.’ is 
probably a synonym of this species.

In India the roots are reputed to have astringent and tonic properties, and 
are employed for fevers and nervous and urinary affections. In some parts 
of Africa they are used as a remedy for rheumatism, because of their sup- 
posed diuretic properties. The leaves are employed in India for ophthalmia 
and the juice of the root for ulcers, and aphrodisiac properties are ascribed 
to the plant.

The branches of this and other species of Sida are often used in Mexico for 
making rough brooms. In Yucatén the bark fiber is used for the manufacture 
of twine and hammocks. The plant is said to furnish good forage for horses and 
sheep. The leaves and young shoots rubbed in water give a lather which may be 
used for shaving, especially in the case of a tender and irritable skin. In India 
the roots are esteemed for their stomachic properties, and they are employed as 
a remedy for ague, dysentery, intermittent fevers, and snake bites.

The leaves are used in some parts of Mexico as a substitute for Chinese tea. 
The strong fiber of the bark is utilized for various purposes. The plants are 
much eaten by cattle, and they are very common weeds about houses and in 
fields. Maiden reports that in Australia fowls are sometimes killed by eating 
the ripe carpels, the sharp points irritating the digestive canal and causing 
inflammation. In Costa Rica a decoction of the roots is used as a remedy for 
infantile diarrhea.

by E. L. Greene.* The roots of L. plebeia Sims, which somewhat resemble 
parsnips, are used as food by the natives of Australia. The fiber of the same 
species was utilized by the aborigines for the manufacture of baskets and 
fishing lines, and the stems have been tested successfully for paper making.

15. MALVAVISCUS Cav. Monad. Diss. 131. 1780. 


Shrubs or trees; leaves toothed, often lobed or angled; flowers usualy red, 
pedunculate, axillary or racemose; bractlets numerous; petals erect-connivent, 
or spreading only above; fruit 5-celled, the carpels baccate, indehiscent, 
1-seeded. 

The differences between most of the species are poorly marked, and most 
of the characters are so variable that there is much doubt as to which ones 
are of systematic value. The following treatment is not wholly satisfactory, 
but the writer is uncertain whether the number of recognized species should 
be increased or decreased. 

Various species of Malvaviscus are cultivated in Mexico and elsewhere for 
their showy flowers. Among gardeners they are frequently known by the 
generic name Achania. The bark contains a tough fiber. A decoction of the 
flowers is employed in Mexico for inflammation of the digestive tract, and in 
popular practice as an emmenagogue. The plants have the emollient properties 
characteristic of the family. 

One of the species is figured by Hernéndez,* without name or description. 
Another one, apparently, is illustrated and described’? in a chapter headed 
“De Atlat Zopillin, seu aquosa herba appensa.”

(Coahuila). 

The Coahuila specimens were taken from a cultivated plant, and the shrub 
is cultivated elsewhere in Mexico. Palmer reports that a decoction of the 
flowers and peach leaves is a local remedy for deafness, and that the flowers 
are steeped in mescal to prepare a drink for coughs and colds.

de Guinea” (Porto Rico). 

The English names are “ roselle’”’ and “ Jamaica sorrel.” The plant is often 
cultivated for the fleshy red calyces, which are mucilaginous, with acid flavor, 
and are used in the preparation of jellies and sauces. The leaves also are 
sometimes used for flavoring food. In India the plant is of importance be- 
cause of the fiber of the stems, which is separated by retting and employed 
for cordage. The seeds are said to have demulcent, diuretic, and tonic prop- 
erties, and the ecalyces are employed in the preparation of cooling beverages 
for fever patients.’

playa” (Panama) ; “nau” (Hawaii); ‘“ fau” (Samoa); “pago” (Guam). 

The word “ majagua’” has been corrupted in English into ‘ mahoe,”’ the 
name used in Jamaica and elsewhere. The wood is white, soft, and porous, 
and is said to weigh 35 to 388 pounds per cubic foot. It is sometimes utilized as: 
a substitute for cork. The plant was an important source of fiber in the Western 
Hemisphere before the arrival of the Huropeans, and is still used extensively 
for cordage. It was employed in many parts of the Tropics for the manufacture 
of mats and coarse cloth. In quality the fiber is similar to jute, and it has the 
property of becoming stronger after being soaked in water. 'To the flowers, 
roots, and bark are ascribed aperitive, emollient, sudorific, and laxative proper- 
ties. In the Pacific islands the bark was sometimes eaten when other food was 
lacking. The aborigines of Queensland value the roots as food, likewise the 
leaves, which have a slightly acid flavor. In Samoa the bark is used for strain- 
ing the narcotic drink ava. In Guam ropes of it, after having been oiled, are 
employed as cables. For an illustration of the plant see Contr. U. S. Nat. Herb.

The Chinese hibiscus is one of the most common ornamental shrubs in tropi- 
cal America, and is cultivated also in hothouses in temperate regions. The 
flowers are often double, and they occur in many shades of red and yellow, 
some forms having variegated petals. In India the shrub is known as “ China- 
rose,” “ shoeblack-plant,” or “‘ shoe-flower plant.” The latter names are derived 
from the fact that the petals, which turn black when crushed, are used for 
blacking shoes. They are employed by the women of China to dye the hair 
and eyebrows. The flowers are sometimes pickled and eaten in China, and they 
are used to color spirituous liquors. The petals impart to paper a bluish 
purple tint which reacts like litmus. The bark is employed in China as an 
emmenagogue. 

A related species (known in Porto Rico as “lira”? and in Colombia and the 
Philippines as “arafa”) is H. schizopetalus (Mast.) Hook., which likewise 
is cultivated in Mexico. It is distinguished by having recurved petals which 
are cut into narrow lobes. Still another species cultivated in Mexico is the 
Rose-of-Sharon or althea, Hibiscus syriacus L. (“ altea,” “flor de una hora”), 
an Asiatic plant. It is similar to H. rosa-sinensis, but has mostly smaller flow- 
ers, Single or double, pink, purple, or white, with a very short stamen column.

REFERENCE: George Watt, The wild and cultivated cotton plants of the world, 
1907. 

Shrubs or large herbs, sometimes small trees; leaves usually 3 to 9-lobed; 
flowers large, yellow or purplish, the calyx subtended by 3 large cordate bracts; 
calyx truncate or shallowly 5-lobate; fruit a loculicidal capsule, the seeds com- 
monly covered with long cotton. 

The cultivated species of the genus are greatly confused and poorly under- 
stood. This is due chiefly to the fact that many of the cultivated forms are 
the result of hybridization. 

Cotton is, of course, one of the most important plants of Mexico, where it 
has been in cultivation from ancient times. The early European visitors men-

tion frequently the cotton garments worn by the natives, who showed great 
skill in their manufacture. Cotton is now one of the most valuable of cultivated 
crops in Mexico. 

The general Spanish word for cotton is “algod6n.” This is frequently modi- 
fied by various varietal names. The name for the plant is “ algodonero.” The 
following additional names are reported: “Taman” (Yucatéin, Maya) ; 
“xurata” (Michoacén); “xchup” (Yucatén, Maya); “cuinim” (Huastec) ; 
“icheatl” (Nahuatl) ; “tidy,” “dehti” (Otomf, Buelna) ; “ pishm” (cotton), 
“pishten-kiup ” (the plant), “ pishten-puih” (the flower), “pishten” (cotton) 
(Mixe, Belmar). 

The root bark of cultivated cotton is official in the U. S. Pharmacopoeia. 
It has emmenagogue properties and is sometimes employed to facilitate parturi- 
tion, but at present it is little used. By the slaves of the South in former days 
it was employed as a means of producing abortion. The plant is said to 
be used in Mexico for the same purposes, an infusion of the leaves and flowers 
is employed as a gargle for sore throat, and an infusion of the roasted seeds for 
dysentery and similar affections. 

Besides the fiber obtained from the cotton plant, a valuable product is found 
in the seeds. These yield an oil which is applied to a wide variety of uses, 
and the residue left after the extraction of oil is an important source of 
fertilizer and of food for stock.

Shrub; leaves cordate at base, 3-lobed to about the middle, 8 to 13 em. 
long, glabrous except along the veins; the lobes ovate-lanceolate, very long- 
acuminate; bractlets ovate-cordate, acute, entire, covered with large purple 
dotlike glands; calyx 8 to 9 mm. long, purple-dotted; petals 5 to 5.5 cm. long, 
purplish when dry. 

In a general way the specimens agree with a tracing of the plate which 
served as the basis of De Candolle’s description of Ingenhouzia triloba.1 The 
writer feels convinced, however, that the two plants are different. The identi- 
fication of Ingenhouzia is still uncertain, and it may well be that the plant 
has never been recollected. By many authors it has been held to be the same 
as Thurberia thespesioides A. Gray, but that view is undoubtedly incorrect.

*Juan José Martinez de Lexarza was born at Valladolid (now Morelia) in 
1785. At the age of 12 he became a student in the Colegio de Mineria in the 
City of Mexico and later graduated with great distinction, his synodic being 
no less a person than Humboldt. He was unable to continue his mineralogical 
studies, and returned to Michoacfén, where he became a member of the provin- 
cial militia and rose to the rank of first captain. He made the acquaintance of 
La Llave, who was established at the Cathedral of Morelia, and that distin- 
guished naturalist interested him in botany. In 1824-25 they published jointly 
descriptions of a number of new genera of Mexican plants and various species 
of orchids. Lexarza became an enthusiastic student of orchids, and devised a 
special classification for them, based upon seed and pollen characters. He ex- 
plored various regions of Mexico, and promised to become one of the accom- 
plished botanists of his day, but his great industry proved his undoing and he 
died in 1824.

Reported from Oaxaca and Veracruz; originally described from Izficar, 
Puebla. Guatemala and El Salvador. 

Tree, often 20 meters high, with broad dense crown; leaves oval or elliptic, 
short-petiolate, 138 to 40 cm. long, obtuse to acuminate, rounded at base, glab- 
rous except for the tufts of hairs in the axils of the veins beneath; flowers 
short-pedicellate; calyx bracteolate, tomentulose; petals pure white, linear-

In connection with the original description of the genus Lerarza, La Liave’* 
gives the following account of the tree: “ The President of the Republic, Guada- 
lupe Victoria, while on a military expedition to the southern region, between 
Oaxaca and Angelopolis, passing through IzGcar and admiring the funereal 
majesty of Lerarza, had sent to me a branch with flowers and fruit, that a 
description might be drawn of it; afterward my colleague, Doctor José Ignacio 
Luna, sent a drawing of the tree, with accurate measurements, adding the 
information that to the splendid shelter formed by the lower branches of the 
tree, the primitive inhabitants were wont to come to mourn their dead. He 
stated also that flowers were added to the pozonque (a cold drink made of 
cacao) which they use at weddings and festivals, to give flavor to it, for 
which reason, perhaps, the tree is given the vernacular name of cacahoazochitl, 
which may be rendered into Spanish as flor de cacao. According to the same 
authority, no other tree of the same sort is found at Izicar or elsewhere in 
the region, but Doctor Miguel Valentin, of Huamantla, no mean student of 
natural history, after reading the description of the tree, assured me that 
when he was making a journey through the Mixteca he observed trees similar 
to this.” 

In Costa Rica the young shoots of some species (known as “ garrocho” and 
“ molenillo”’), which develop their branches, like cacao, in whorls of 5, are 
used to make “ molenillos,” the utensils with which chocolate is beaten to a 
froth.

1Don Pablo de La Llave was born in the city of Cérdoba, Mexico, in 1778. 
He was educated in the Colegio de San Juan de Letran, in that city, and later 
gave courses in philosophy in the same institution. He pursued ecclesiastical 
studies and received the degree of doctor of theology when he was scarcely 19 
years of age. In 1801 he went to Spain to continue his studies, this course 
being necssary during the Spanish domination, since at that time the offices 
of the church were given only te those who had been born in Spain or educated 
there. He became deeply interested in natural history, especially botany, 
and was finally appointed director of the botanical garden at Madrid. He 
took an interest in political affairs, also, and in 1812 was elected a deputy of the 
Cortés. In 1823 he returned to Mexico, and was appointed Minister of Justice 
and Ecclesiastical Affairs, a position which he filled until 1825. In 1830 he 
was president of the Senate chamber. La Llave died in 1833. He published 
numerous biographical and patriotic papers and treatises upon natural science. 
He was associate author, with Lexarza, of the Novorum Vegetabilium Descrip- 
tiones, published in 1824-25. He described several new genera of plants, most 
of which were dedicated to the heroes of the Mexican war of independence.

Oaxaca. Type from “Costa Grande,’ Guatemala. 

Tree, sometimes 40 meters high, with broad crown; leaflets usually 5 or 6, 
oblong-oblanceolate, petiolulate, 10 to 22 em. long, acute or acuminate, glabrous; 
whole inflorescence bright red, obscurely puberulent ; calyx 1 em. long, shallowly 
bilobate; petals recurved; stamen tube long-exserted, the anthers clustered at 
the apex; fruit brown, ellipsoid, 20 cm. long, glabrous within; seeds (including 
the long wing) about 5 cm. long. “ Palo calabaza,” “ palo de perdiz” (Oaxaca). 

The wood is described as soft and spongy. 


4. CEIBA Medic. Malvenfam. 15. 1787. 


Trees, often very large, the trunk and branches often armed with spines; 
leaves digitate, the leaflets 5 to 7, usually serrate; peduncles axillary, 1-flow- 
ered, the flowers large or small; calyx truncate or 5-lobate; petals oblong or 
linear-oblong, hairy outside; stamen tube short, dividing into 5 long branches, 
each of these bearing a few crowded anthers at the apex; capsule woody, 5- 
celled, densely lanate within, the seeds small. 

The species of Ceiba (of which Hriodendron is a synonym), Pachira, and 
Bombazx have been much confused in Mexican literature and in botanical pub- 
lications in general. The following Mexican-names are reported for plants 
whose identity is doubtful, although they belong to one of these three genera: 


“ Escobetilla,” ‘“pit6n” (Morelos); “thura’” (Michoacan, Tarascan) ; “ kuy- 
ché” (Yucatan, Maya); “tumbile’” (Michoacin); ‘ yaga-xeni” (Oaxaca, 
Zapotec). 


The trees of this group are well known in Mexico as well as elsewhere in 
tropical America, particularly because of their large size, broad crowns, and 
extensive buttresses. One of the earliest references to the ceiba trees in 
Mexican literature is by Bernal Diaz del Castillo who, in his True History of 
the Conquest of Mexico, relates how, in 1519, in the Indian town of Tabasco on 
the Rio de Grijalva, after having defeated the natives in battle, Cortés took 
possession of the country in the King’s name by drawing his sword and making 
three cuts in a great ceiba tree which stood in the central plaza of the town. 
Later Diaz states that on Palm Sunday “a cross was made in a large ceiba 
tree on the spot where the battle was fought, in order to afford a long memorial 
thereof, for this tree has the quality of preserving scars on its bark.” 

Oviedo (Lib. IX, Cap. XI) gives an interesting account of the ceiba or 
cotton trees, as follows: ‘In the chapters in which I treated of the oak and 
mahogany I spoke of their size, and on the mainland there are many such

trees and others still larger. If I should speak of these things without hav- 
ing seen them I should be afraid to mention them; for it is the custom of 
fault-finders not to content themselves with repudiating those things which 
in themselves are doubtful, but to contradict things that are publicly known. 
But since I know that I speak the truth, it does not bother me if the ignorant 
revile me, for barking dogs do not bite. I may say then that at a league’s 
distance from the city of Darién, otherwise known as Santa Maria del An- 
tigua, runs a very wide and deep river called Cuti. Before the Christians 
took possession of that country, the Indians had thrown down a stout tree 
which erossed that river from bank to bank; it was in a place where we were 
constantly crossing to go to our mines and plantations. The tree was very 
long and thick, but it had been there for some time and had sunk in the 
middle. Although we passed along the upper side, there was one stretch where 
the water came to the knees, and every year it lowered a little more, because 
the stream wore away the banks on which the trunk rested. Wherefore in the 
year 1522, when I was magistrate and captain in that city, I had another 
tree growing on the bank thrown across the stream a few paces below. 
When cut down it stretched clear across the river, and 50 feet besides; and 
the river was more than 100 feet wide. This tree where it was thickest was 
16 palms or more in diameter. * * * In comparison with many other 
trees in the region, this was a small one.’ * * * “Jn Hispaniola there 
was a tree, eight leagues from this city, where it had the name of the drbol 
gordo, of which I have often heard the Admiral Don Diego Colén speak, and 
I have heard him say that he and fourteen other men, taking hold of hands, 
could not reach around it. * * * To me this is not remarkable, remem- 
bering still larger ceyba trees that I have seen on the mainland. In the 
province of Nicaragua are the largest trees I have yet seen, which greatly 
surpass those I have mentioned; I shall speak only of a.ceyba which I saw 
many times, less than half a league from the residence of the Cacique of 
Thecoatega, beside a river of the town of the Cacique of Guacama, which 
belongs to the grant of a man called Miguel Lucas, or his companions Fran- 
eisco Niiiez and Luis Farfin. This tree I measured with my own hands by 
a cabuya cord, and found its circumference at the base to be 33 varas, or 132 
spans [S88 feet]; and since it stood on the bank of a river it was not possible 
to measure the lowest portion of the roots; if properly measured, I judge its 
circumference would have been 36 varas or 144 spans [96 feet]. This had 
the thickest trunk of all the trees I have seen. The wood of the ceyba trees is 
spongy, easily cut, and light, and the tree is unimportant except for two 
things: One is its wool and the other its vast shade, for the branches are 
very wide-spreading, and the shade is wholesome, not oppressive like that of 
other trees of the Indies, which is notoriously harmful. * * * The wool 
is short and I do not believe it could be spun; but for pillows and cushions 
it is unique in its softness, and no feathers, wool, or cotton equal it; but if wet 
it forms into balls and is spoiled. * * * The Indians of Nicaragua have 
places set aside for the tiangiiez or market, and there they have two, three, 
or four of these ceyba trees for shade, which are sufficient to shelter one to 
two thousand people. * * * In the province of Nicaragua this tree is 
ealled poxrot, and in other places it has other names.”

Sonora (cultivated), Tepic, Guerrero, Yucatin, Veracruz, and Tamaulipas. 
Widely distributed in tropical America, Asia, and Africa. 

Large tree, sometimes 40 meters high, with spreading crown; trunk often 
with large buttresses at base, the bark gray or green, smooth but covered with 
large conical spines; leaflets 5 to 7, oblanceolate, oblong, or obovate-oblong, 
8 to 20 cm. long, acuminate; calyx 1 to 1.5 em. long; flowers white or pink; 
petals silky-hairy outside; fruit elliptic-oblong, 10 to 12 cm. long, the brown 


seeds imbedded in the silky “cotton.” ‘“ Ceiba,” “ ceibo” (Yucatan, Oaxaca,

cruz, Campeche, ete.) ; “ cabellos de angel,” “ pitén,” ‘ xiloxochitl” (Herrera) ; 
“ceibén ” (Nicaragua). 

The usual English name is “ silk-cotton tree.” The tree grows very rapidly. 
The wood is white and soft, with a specific gravity of about 0.520. The trunks 
are often used for canoes, because the wood is so easily worked, and the wood 
is employed also for making packing boxes and matches. The most important 
product of the tree is the silky fiber enveloping the seeds, which is very fine, 
light, and elastic, and does not become matted under pressure. Large quanti- 
ties of it are exported from the East Indies and West Africa under the names 
“ kapok,” “kapoe,” and “ kapok fiber.” It is employed for stuffing mattresses, 
pillows, life preservers, and other articles. The silk is employed locally in 
Mexico and is exported in small quantities. It is said to be worth about $1.50 
(silver) per kilogram. The silk has been used in England for making beaver 
hats. 

The seeds yield an oil used for illumination and for the manufacture of 
soap. The buttresses at the base of the trunk are often very wide and so 
thin that they are sawed into large pieces to be used as doors for native houses. 
The leaves are reported to be cooked and eaten at times. The large flowers 
are eaten by stock as they fall to the ground. The bark is applied to wounds, 
and taken internally it is reputed to have emetic, diuretic, and antispasmodic 
properties.

The fruit is said to be as large as a coconut. The tree usually grows along 
river banks. The seeds fall into the water, where they germinate and float 
about with expanded cotyledons until they reach the bank and take root. The 
leaves and flowers are said to be employed to relieve inflammation of the eyes, 
and the seeds to be employed as a substitute for cacao. 

Pachira longifolia appears to be intended as a new name for P. macrocarpa,

apex, thinly tomentose when young but in age nearly glabrous, thin; calyx 
about 1.5 em. long, commonly with 10 glands at base; petals 7 to 13 cm. long,

The tree blooms when leafless. The handsome flowers are often gathered for 
decorations in churches and for similar purposes, and they were esteemed by 
the Mexicans as one of their most beautiful flowers. The decoction of the bark 
and root is used as a remedy for toothache and to harden the gums. 

This is probably the tree illustrated by Hernandez’ and described in a chap- 
ter entitled ‘‘ De Xiloxochitl, Flore Capillaceo.” He states that the bark was 
highly valued as a remedy for ulcers, and for its diuretic properties. 

Bombaz ellipticum has been reported from Yucatéin as Pachira fastuosa 
Decaisne and P. alba (Lodd.) Walp., and Mexican reports of Bombaz ceiba L., 
an Old World species, are probably referable here. Hemsley gives no reasons 
for his segregation of B. mexicanum. The numerous specimens seen by the 
writer exhibit some variation, especially in the size of the flowers, but all (in- 
cluding some from the type locality of B. mexicanum) appear to be conspecific.

STERCULIA OBLONGIFOLIA DC, Prodr. 1: 482. 1824. Described from Mexico, the 
description based upon one of Sessé and Mocifio’s drawings. According to Hors- 
field and Bennett, this is Cola acuminata (Beauv.) Horsf. & Benn., the cola nut, 
an African tree which is cultivated in tropical America. The writer has seen 
specimens from Jamaica and Costa Rica but none from Mexico.

Mountains of Oaxaca, and often cultivated elsewhere. Guatemala. 

Tree, 12 to 15 meters high, the trunk often 40 cm. in diameter; leaves long- 
petiolate, 12 to 30 cm. long, acutish to acuminate, deeply cordate at base, irregu- 
larly and shallowly 3 to T-lobate or nearly entire, glabrate above, stellate- 
tomentose beneath; peduncles short, 1-flowered, opposite the leaves; calyx 
campanulate, 3.5 to 4.5 em. long, deeply 5-lobate, green, streaked with red, 
with a large pit inside at the base of each lobe; petals none; stamen column 
elongate, dividing into usually 5 branches, these linear, simulating long 2-celled 
anthers; capsule narrow, about 15 cm. long, deeply sulcate, loculicidally 5- 
valvate, hispid within; seeds small, black and shining, with a fleshy appendage 
at the hilum. ‘“ Mapastchil” (the flower; from the Nahuatl, macpal-xochitl, 
“hand-flower”’) ; ‘‘ macpalxochicuahuitl”’ (the tree; Nahuatl); “arbol de las 


manitas,” “flor de manitas,” ‘“‘manita de leén,” “mano de leén” (Mexico) ; 
“teyaqua” (Michoacin, Ledén) ; “ palo de tayuyo,” “mano de mico” (Guate- 
mala). 


The hand-flower tree is one of the most celebrated of Mexican plants, and 
was well known to the early inhabitants. It is restricted in its distribution, and 
for a long time the only tree known to the residents of the Valley of Mexico 
was one growing at Toluca. Even long after the Conquest this was believed 


STANDLEY—TREES AND SHRUBS OF MEXICO. 197 


to be the only tree of its kind, except for its progeny planted elsewhere in the 
valley. The stamens bear a striking resemblance to a hand and wrist with 
outspread fingers, and because of the remarkable form of the flowers the tree 
was viewed with veneration. Trees of this species are of frequent occurrence 
in the gardens of the City of Mexico and elsewhere. 

The tree is figured by Hernindez* under the name “ Macpalxochi Quahuitl,” 
but without description. Cervantes reports that the infusion of the flowers 
was employed by the Indians of Toluca as a remedy for inflammation of the 
eyes and for hemorrhoids.”

Fremontia mexicana Macbride, Contr. Gray Herb. n. ser. 53: 14. 1918. 

Mountains and foothills of Baja California; described from a cultivated 
plant, from Ensenada. Southern California. 

Shrub or small tree with red-brown branches; leaves long-petiolate, palmately 
3 or 5-lobate, 2 to 4.5 cm. long; deeply cordate at base, green above, sparsely 
stellate-pubescent, whitish or yellowish beneath and covered with a dense close 
stellate tomentum, the lobes rounded, sometimes again lobate; flowers solitary, 
opposite the leaves, on short peduncles; calyx open-campanulate, 2.5 to 3.5 em. 
long, corolla-like, yellow tinged with red, stellate-pubescent, the lobes rounded 
and apiculate, each with a large glabrous gland at base; petals none; capsule 
4 or 5-valvate, densely hairy. 

Fremontodendron californicum (Torr.) Coville is distinguished from F. 
mexicanum by the densely hairy glands at the base of the calyx. It has hard 
close-grained red-brown wood, with a specific gravity of about 0.71. In Cali- 
fornia the tree is sometimes known as slippery elm, because of the resemblance 
of its inner bark to that of Ulmus fulva. The genus is named for Col. John 
Charles Frémont, one of the earliest explorers of the western United States.

’ Nearly throughout Mexico. Widely distributed in the warmer parts of the 
Western Hemisphere. 

Shrub, 0.5 to 2.5 meters high; leaves on long or short petioles, oblong to 
broadly rhombic-ovate, rounded to acutish at apex, rounded or subcordate at 
base, crenate or dentate, thick, usually densely and finely tomentose on both 
surfaces; flowers in loose cymes, mostly pedicellate; petals pink to violet, 8 to 
18 mm. long; fruit 7 to 9 mm. long, long-beaked, the lobes rounded to acutish 
below. “ Malvavisco” (Porto Rico); ‘ bretdénica’” (Porto Rico, Venezuela) ; 
“malva,” “ varita de San José” (Nicaragua). 

The plants vary considerably in size of flowers and leaves, in density of 
pubescence, and in form of the fruit, but none of the proposed segregates seem 
worthy of recognition. M. arida is a small-leaved form of dry regions. M. spe- 
ciosa is a form with unsually large flowers and rather scant pubescence. Wat- 
son compared the latter, in his original description, with 4. pyramidata, from 
which, of course, it is amply distinct. To the present writer it seems not 
improbable that M. pyramidata and M. tomentosa may at times bybridize.

In forests from Colima to Chiapas and Tabasco, and cultivated extensively 
in the warmer parts of Mexico. Central America; cultivated in the Tropics 
of both hemispheres. 

Small evergreen tree, 6 to 8 meters high, or sometimes larger, with spreading 
branches, the lateral branches in clusters of 5, rarely 4 or 6, the young shoots 
hirsute or hirtellous; leaves short-petiolate, elliptic-oblong or obovate-oblong, 
15 to 80 cm. long, rounded or obtuse at base, abruptly acuminate at apex, 
thick; inflorescences small, fleshy, borne along the trunk and main branches; 
flowers long-pedicellate, the calyx pink, its lobes lance-acuminate, 6 to 7 mm. 
long; petals yellowish; fruit 30 cm. long and 10 cm. thick or smaller, 
elliptic-ovoid, with a thick fleshy rind, longitudinally ridged and furrowed, red, 
yellow, purplish, or brown, each cell containing 5 to 12 large, brown or purple 
seeds embedded in white or pinkish, acid pulp. 

The word “cacao” is the name of the plant and of the crude product from it. 
Cocoa and chocolate are manufactured products obtained from the seeds. 
The word ‘“ cacao ”’ is derived from the Nahuatl “ eacahuatl” (written also caca- 
hoatl), a term which in modern Mexican has been corrupted into “ cacahuate,” 
the name applied to the peanut, the application evidently because of the 
resemblance of the peanut to cacao fruit. The Nahuatl name for the cacao 
tree is ‘“ cacahuacuahuitl,” which has been written also as “ cacaotlquahuitl,” 
“ cacauquauitl,” and in various other ways. The following additional names 
are reported from Mexico: “ Bizoya,” “yagabizoya”’ (Oaxaca, Zapotec, Reko) ; 
“déqhy’”’ (Otomi, Buelna); “caocauatzaua” (Zoque, Gonzales); “kako” 
(Mixe) ; “cahequa” (Tarasean, Ledn) ; “ chudechu” (Otomi!). 

Of all the numerous vegetable productions of the New World, and especially 
of Mexico, none is more celebrated than the product of the cacao plant, which 
attained high favor in Europe immediately after the Conquest. Oviedo, who 
describes the plant at great length, states that it was not found in the West 
Indies, but only on the continent, especially in Mexico, and he terms it “the 
most precious tree of the Indians and the most highly esteemed.” 


806 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


Cacao in its wild state was well known to the early inhabitants of Mexico, 
and it was also cultivated, although to what extent is uncertain. The use of 
the drink made from the seeds was confined chiefly to the higher classes, but 
the use of the seeds aS money was a matter of importance to all classes, for 
eacao seeds were the basis of the Mexican financial system. They are still 
used locally in Mexico as a substitute for small coins. Jourdanet, in his 
translation of Sahagtn,* gives the following account of the use of cacao as 
currency: ‘It would be idle to call attention to this plant, whose fruit is so 
widely used to-day, if it were not of interest to recall the fact that cacao was 
unknown in Hurope before the discovery of America. The Mexicans at the 
time of the Conquest made much use of it, in various forms, none of which 
was the equivalent of our chocolate. This precious fruit was besides, for the 
richest among them, a means of treasuring their wealth, and a medium of 
exchange, which facilitated commerce as does our money. This custom was 
even extended after the Conquest in certain parts of the country, so long, in 
fact, that I myself observed in Yucatan, before 1850, that cacao seeds were 
used in place of copper coins. 

“Tt would be very difficult to determine what was the value set upon the 
cacao employed as money in ancient Mexico. * * * However, in the part 
of the country where cacao has continued in use as currency up to the present 
time, its value in ordinary market transactions is not the same as that assigned 
to it when it is sold at wholesale as a food. The cacao seed, as money, keeps 
a conventional value which, as a rule, is much greater than its market price. 
That is to say, its usage in this sense is limited to transactions of little im- 
portance, as a means of making small change, in the Provinces where copper 
coins are not in circulation. 

“To return to ancient times, we may take the judicious and always reliable 
accounts of M. Garcia Icazbaleeta, and state that, ‘in accordance with the 
numeral system of the Mexicans, the base for counting cacao seeds was the 
number 20. Thus, 400 seeds (20X20) formed a tzontli. We know that tzontl 
in the Nahuatl language means four hundred. Even to-day it is the custom in 
the City of Mexico to sell fire-wood by tzontles of 400 sticks. Twenty tzontlis, 
that is 8,000, made a wziquipilli, and three gviquipilli a load, which therefore 
consisted of 24,000 seeds. Since this system of accounting was clumsy and could 
result in abuses, it was forbidden by an official order of January 28, 1527. 
It was forbidden to sell cacao by count of the seeds, and ordered that the sale 
should take place by full measure, guaranteed by the municipal seal. Later, 
by an order of October 24, 1536, it was decreed, on the contrary, that the seeds 
should be counted for sale, and that no other method should be followed.’ 

“We have stated above that the Mexican nobles used cacao as a means of 
hoarding their fortunes. The twofold use made of it, as food and as money, 
caused it to rank as a basic element of wealth. The districts which produced 
cacao paid it as tribute to the rulers, in vast quantities. Torquemada states 
that in the palace of the famous King of Tetzcuco, Netzahualcoyotl, there was 
expended every year 2,744,000 fanegas of cacao (the fanega is the equivalent 
of about 40 kilograms). That is scarcely credible, although this author assures 
us that he had seen the book of accounts approved by a grandson of the King. 
Both Torquemada and the chronicler Herrera report that the Indian auxiliaries 
of Cortés pillaged a cacao granary belonging to Monteuhcoma, where they 
found more than 4,000 loads. The seeds were stored in osier baskets so large 
that six men taking hold of hands could not span them. The amount carried 
away was 600 loads, for which it was necessary to empty only six baskets.

“Tt would be difficult to give an exact idea of the extent and character 
of the lands employed to advantage by the ancient Mexicans for the culture 
of cacao. It is certain that the chief places of production were to the south 
of the country, bordering on Guatemala. It is there that this precious plant 
is still cultivated, and to-day as in former times it is the district of Soconusco 
which gives the product of best quality.” 

Oviedo states that those persons who had cacao trees growing upon their 
lands were considered rich. “In the province of Nicaragua,” he relates, 
“a rabbit is worth 10 seeds, and for four you can buy eight nisperos; a slave 
is worth a hundred, more or less. * * * Hyven with these seeds there are 
ways of cheating, such as putting false or empty shells among a quantity of 
them. These spurious ones are prepared by separating the shell and filling it 
with earth or some other substance, then the shell is closed so carefully that 
the substitution is not perceptible. He who receives them, when he counts 
them, touches them one by one with the forefinger, and no matter how well 
the counterfeit has been performed, it is detected by the touch.” Acosta men- 
tions the fact that cacao seeds were given as alms to the poor. Bernal Diaz 
del Castillo relates how upon his return to Mexico after his long journey 
back from Guatemala, Cortés “‘ sent us presents of necessaries, likewise gold 
and cacao for our expenses.” 

Theobroma cacao is the principal source of the chocolate and cocoa of com- 
merce, but other species also are planted, some of them extensively. Cacao 
is grown commercially in Mexico, especially in Chiapas and Tabasco. At an 
early date it was introduced into the Canaries and Philippines, and now 
it is grown extensively in many parts of the Old World tropics. Numerous 
minor varieties, differing in the form of the fruit, are known. The quality 
of the product varies greatly in different countries. The young trees must be 
grown under shade. Chocolate is the term applied to sweetened prepara- 
tions of the roasted and ground cacao seeds, with a large proportion of the 
original fat retained. Cocoa is prepared in the same way, but most of the 
fat is removed from it. 

The original inhabitants of Mexico sometimes ate the seeds either green 
or dry, but the seeds were used chiefiy for the preparation of a drink known 
as “ xocoatl,” this being the term from which the word chocolate is obtained. 
The word zocoatl signifies “sour water,’ the unsweetened decoction of the 
seeds being unpleasantly bitter. The drink as prepared by the Mexicans was 
different from the chocolate as now usually prepared. It consisted of a strong 
decoction of the seeds, flavored with chile, maize, honey, ceiba seeds, and many 
other substances, and the beverage was beaten into a foam which dissolved 
almost imperceptibly upon the tongue. It was often colored with Biza orellana. 
It was the favorite drink of the Mexican nobility, who consumed immense 
quantities of it. It was a favorite also of the emperor, for whom almost 
incredible quantities were prepared every day. A drink still much used in 
some parts of Mexico is “chilate’” (in Nahuatl chilatl, chile-water, or chil- 
cacohuatl), which is made from cacao, chile, and water. Similar drinks are 
prepared also by the addition of other substances. 

Chocolate was one of the first Mexican products to come to the notice of 
the Spanish invaders of Mexico, all of whom were enthusiastic in its praises. 
Cortés mentions it in his letters to the King of Spain. After the Conquest 
it was an esteemed drink among the Spanish settlers, and it is related that 
in Chiapas the ladies had it brought to them even in the churches, until the 
bishop forbade the servants who brought it to enter the church buildings. 
Acosta is a unique exception to the Spanish proponents of chocolate. He Says:

“They esteem it highly in this country, foolishly and for no good reason, for 
it injures the hearts of those who are not accustomed to it, and there is a 
froth on top of it which is very unpleasant if one is not accustomed to 
it. * * * Those who are not accustomed to it from childhood care little 
for it.’ Acosta, however, found little to praise in the New World. 

Cacao seeds contain 45 to 50 per cent of oil, or cacao butter, which is much 
used in pharmiucy for making ointments. They also contain an alkaloid, 
theobromine. The oil was used by the inhabitants of Mexico for treating 
wounds, and the beverage made from the seeds was considered beneficial to 
the health. Oviedo reports a belief that if a person drank chocolate for 
breakfast, the bite of a poisonous serpent would not be fatal to him. 

Cacao is illustrated and described at length by Hernindez.* 


2. Theobroma angustifolium DC. Prodr. 1: 484. 1824. 

Chiapas and Tabasco, and perhaps elsewhere. Central America. 

Small tree with spreading crown, the bark smooth; leaves oblong or oblong-

This species is one of the important cacao plants of Mexico, and the notes 
given above under 7’. cacao apply in large part to it also. In Chiapas Theo- 
broma angustifolium is the species generally grown. The region of Soconusco 
has long been famous for its chocolate, derived from this species, and for 
many years the supply for the royal family of Spain was brought from 
Soconusco.

Honduras) ; “ guacimo macho” (Venezuela) ; “ guacimillo” (Nicaragua). The 
name ‘“ guayacin’”’ has been reported as in use in Mexico for this species, but 
the report is probably incorrect. 

The trunk is often 30 to 40 cm. in diameter, and is covered with rough or 
smooth, gray or blackish bark. The wood is light, fibrous and coarse-grained, 
grayish, slightly tinged with red or pink, with a specific gravity of 0.552 to 
0.580. It is rather strong and resistant, and has been employed for ribs of 
small boats, shoe lasts, barrel staves, house furniture, paneling, firewood, and 
other purposes, and as a source of charcoal for gunpowder. The young stems 
yield a strong fiber, suitable for making rope. The juice has been employed 
to clarify syrup in the manufacture of sugar. Silkworms have been fed on 
the leaves and stock browse upon the leaves and young shoots. 

The fruit is green at first but black at maturity. When fresh it is rather 
fleshy or pulpy and mucilaginous, and has a pleasant, sweet flavor. It is 
sometimes eaten by people, especially in times of scarcity, either raw or 
cooked. Sometimes, when dry, it is ground and then cooked. Pigs are said 
to be fond of it. The flowers are said to furnish a good quality of honey. 

The plant is much employed in domestic medicine. The bark and other parts 
are administered for malaria, cutaneous and syphilitic affections, elephantiasis, 
diseases of the chest, leprosy, and other diseases. The plant has emollient and 
astringent properties. 

Oviedo (Lib. VIII, Cap. VII) gives the following account of the tree: “The 
Guacuma is a large tree that bears fruit like mulberries, and the leaves are 
like those of the mulberry-tree, but smaller. From the fruit the Indians make

carrying-sticks. This tree is common in all the Indies; I say common, for it is 
found in these islands and in Tierra-Firme, and it is one of the best trees 
for wood that can be found, and excellent for making powder; this I have tried 
in making ammunition for the fortress of the city of Santo Domingo; and 
experienced powder makers say that no other wood is so good for making 
the best powder, not even German willow or filbert branches.” 

The tree is illustrated by Hernindez* under the names of “ quaucholotl” 
and “ guécimo.”

Ayenia cuneata T. S. Brandeg. Univ. Calif. Publ. Bot. 6: 369. 1917. 

Nearly throughout Mexico. Widely distributed in the warmer parts of the 
Western Hemisphere. 

Plants slender, essentially annuai but often becoming suffrutescent; leaves 
very variable in form, lanceolate to suboricular, 1 to 5 cm. long, rounded to 
acuminate at apex, obtuse to cordate at base, dentate, pubescent or glabrous; 
fruit 5 to 6 mm. in diameter, pubescent or glabrate, covered with long or short 
spinelike processes. 

The Mexican plants exhibit great variation in the shape and pubescence of 
the leaves, but the West Indian specimens are rather uniform. None of the 
segregates which have been described seem clearly differentiated from the 
mass of material from the West Indies and the southern United States gen- 
erally referred to A. pusilla, and it has not appeared practicable to recognize 
any of them. The glands of the petals are so variable in size and form that 
they do not furnish a satisfactory basis for specific segregation.

The tough stems are sometimes used in the construction of huts, for tying 
the larger timbers of the framework. The leaves are employed as a substitute 
for sandpaper. 

The seeds of Davilla rugosa Poir, which is known in Nicaragua as “ hoja- 
chigiie’”’ and in Cuba as “ bejuco castafio” are said to have violent and dan- 
gerous emetic-cathartic properties. The bark of one of the Brazilian species 
is reported to yield a black dye.

Scandent shrubs; leaves with numerous parallel lateral nerves; flowers 
paniculate, the panicles terminal or in the upper axils; sepals 4 to 6, spreading, 
the petals of the same number; fruit of 1 to 5 carpels, the ovules numerous but 
the seeds 1 to 5, surrounded by a thin aril. 

The name ‘“ bejuco de agua ”’ frequently applied to these plants is derived from 
the fact that the stems, when cut, yield a large amount of clear water. They 
are often a satisfactory source of water to travelers in the dry tropical forests 
when surface water is absent.

The seeds and leaves are used in domestic medicine, sudorific, antisyphilitic, 
febrifuge, and diuretic properties being attributed to them.

earpels 2, hirsute, 6 to 7 mm. long; seeds black, surrounded by a thin aril; 
wood rather soft, light, coarse-grained, taking a poor polish, its specific gravity 
reported as 0.805, the sapwood thin, light brown, the heartwood somewhat 
darker. ‘‘ Raspa-viejo”’ (Michoacin, Guerrero) ; “ tlachicén” (Oaxaca; from 
the Nahuatl tla-chiquoni, “thing that makes rough,’ Reko); “hoja man”

“chumico palo,” ‘“ curatela’”’ (Panama); ‘‘ vaca-buey,” ‘“ careicillo” (Cuba) ; 
““neralejo’” (Colombia). 

Seler states that in Oaxaca the ground seeds are mixed with chocolate to 
flavor it. The rough leaves, which contain silicon, are widely used as a sub- 
stitute for sandpaper for polishing wood and metal, and for cleaning kitchen 
utensils. The wood is of little value. The bark is said to be rich in tannin 
and to be used in Brazil for tanning skins. A decoction of the leaves is 
employed in Brazil for treating wounds. In some parts of western Mexico 
the tree is abundant and forms dense thickets or low forests.

Veracruz and perhaps elsewhere; type from Mirador, Veracruz. 

Glabrous shrub, epiphytic and more or less scandent; leaves of fertile 
branches lanceolate, 6 to 10.5 cm. long, nearly sessile, acuminate, acute or obtuse 
at base; inflorescence umbel-like, the pedicels 3 to 5 em. long, the apex of the 
rachis bearing several nectaries, these tubular, 7 to 8 mm. long, stalked; sepals 
4, orbicular, 2 mm. long; corolla cylindric. 

The genus is represented by a large number of species in the humid forests 
of tropical America. The nectaries are usually bright-colored. They hang in- 
verted and are filled with nectar, which is much sought by humming-birds and 
insects. The young sterile shoots are very slender and vinelike, and their 
leaves are decidedly different from those of the fertile branches. In sterile 
specimens which probably belong to MM. mexicana the leaves are sessile, ob- 
long or ovate, and only 1 to 3 cm. long. Specimens of these sterile branches 
were reported from Mexico by Liebmann’* as Urostigma scandens, he believing 
that he was dealing with one of the wild figs (Ficus). 

Imperfect Oaxaca specimens evidently represent a second species of the genus 
for Mexico, but the material is insufficient for identification or description. 
The Oaxaca plant is known locally as “ gallitos.”

STANDLEY—TREES AND SHRUBS OF MEXICO. 825 


1. Clusia rosea Jacq. Enum. Pl. Carib. 34. 1760. 

Chiapas. Central America, West Indies, and northern South America. 

Shrub or tree, 3 to 10 meters high, usually epiphytic when young and destroy- 
ing the host plant in age; leaves short-petiolate, 7 to 15 em. long and nearly as 
wide, broadly rounded at apex, rounded or cuneate at base, very thick, with 
numerous close parallel lateral nerves; flowers polygamous; petals 6, white or 
tinged with pink; fruit 8 to 12-celled, 5 to 6 cm. in diameter. ‘Cupey ” 
(Porto Rico, Panama) ; “ copey”’ (Cuba). 

The wood is said to be reddish and to have a specific gravity of 0.876. An 
infusion of the leaves is sometimes employed for chest affections and a decoc- 
tion of the bark (in Venezuela) as a lotion for rheumatism. A gum or 
resin obtained from the fruit was used by the South American Indians as a 
resolutive in treating fractures and dislocation. 

Oviedo (Lib. VIII, Cap. XIV) gives the following account of a tree which 
must be Clusia rosea or some closely related species: ‘‘ The copey is a fine 
tree with good wood, and it has leaves such as I have described above for the 
guiabara or uvero. But the copey is a much larger tree, with smaller leaves, 
and the leaves are twice as thick or more, and better for writing on with a 
pin or a sharp point; the veins of the leaves are more delicate and hinder 
writing less than those of the wvero. In the early times of the conquest of 
Hispaniola and other islands, the Christians made playing-cards of copey 
leaves, and lost or gained much money with them, for lack of better ones; on 
the leaves they drew the kings, knights, knaves, and spots, and all the other 
figures and values that there usually are on cards, just as I have painted here 
the five of diamonds (plate 3, figure 6). As these leaves are very thick they 
held the drawings well. and shuffling did not break them. The fruit of this 
tree I have not seen, although I have often seen the leaves and the trees them- 
selves.”

Domingo,” “zapote Domingo” (Veracruz); ““mamey” (Tabasco, Costa Rica, 
Cuba, Porto Rico). 

The English name for the fruit is ‘‘mammee-apple.” The tree has been 
introduced into Mexico from the West Indies. The trunk is sometimes as much 
as a meter in diameter ; the crown is broad, and the leaves of a deep rich green. 
The fruit varies somewhat in shape, being either globose or ellipsoid; its thick 
leathery skin is russet-colored, and when cut a yellowish sap exudes from it. 
The flesh is firm but juicy; its flavor somewhat resembles that of the apricot, 
especially when cooked. The fruit is eaten raw, often being served with wine 
or sugar and cream; it is also made into preserves or jam. A liqueur, known as 
“eau de créole” or “créme de créole,” is distilled from the flowers in the French 
West Indies. The wood is hard, durable, and beautifully grained, and takes a 
high polish. It is used for building purposes and cabinetwork. 

The gum obtained from the bark is used to extract chiggers from the skin and 
to kill ticks and other parasites upon domestic animals. In Venezuela the 
powdered seeds are used in the same way. and also for cutaneous diseases. 
Febrifuge properties have been ascribed to the leaves.

Frankenia grandifolia campestris A. Gray.’ is a form with smaller narrower 
leaves and shorter pubescence. It has been collected in Coahuila and occurs 
also in Nevada and southern California. 


2. Frankenia palmeri 8. Wats. Proc. Amer. Acad. 11: 124. 1876. 

Chiefly in salt marshes, Baja California and upon the adjacent islands; 
type from the east coast. Southern California. 

Stems woody almost throughout, gray; leaves linear or filiform, mostly 2 to 
6 mm. long but sometimes as much as 10 mm., scaberulous, usually with a white 
incrustation ; calyx 3 to 4 cm. long; stamens 4. 


105. TAMARICACEAE. Tamarisk Family. 
1. TAMARIX L. Sp. Pl. 270. 1753. 


The species are all natives of the,Old World, chiefly of the Mediterranean 
region. Several of them have medicinal properties and some yield dyestuffs. 
Some’ of the species, when punctured by a scale insect, produce an exudate 
known as manna. 


1. Tamarix gallica L. Sp. Pl. 270. 1753. 

Cultivated for ornament especially in the arid portions of northern Mexico; 
sometimes escaping. Native of southern Europe and northern Africa; culti- 
vated in the southern part of the United States. 

Glabrous shrub or small tree, sometimes 9 meters high, with slender branches ; 
leaves alternate, minute, scalelike, sessile, acute; flowers pink or white, in dense 
bracted spikes; sepals 4 or 5; petals 4 or 5, scarcely more than 1 mm. long; 
anthers yellow or purple; fruit a small capsule containing numerous seeds. 

The English names are tamarisk and salt-cedar. In Spain the shrub is 
known as ‘tamarisco,” ‘“tamariz,” ‘“taray,” ‘“atarfe,” and “talaya.” The 
shrub will thrive under the most varied conditions, in either dry or wet ground. 
In the southwestern United States it is a favorite ornamental plant because 
it grows well in the most arid places. It is able also to endure salt and alkali 
in the soil. Frequently it is planted for hedges, and if kept trimmed it forms 
a dense handsome hedge of pale green. The branches suggest those of cedar 
(Juniperus), but they are much more slender. The plant is easily grown 
from cuttings. 

In its native countries the tamarisk is prized as a source of charcoal. The 
branches are used for basketry and wattlework. All parts of the shrub are 
bitter and the bark contains tannin. Tonic, astringent, sudorific, and diuretic 
properties are ascribed to it. In Europe the leaves and branches are sometimes 
employed in the preparation of a kind of beer.

Baja California; type locality, Sebastian Bay. 

Trunk 3 to 18 meters high, tapering from base to apex, with numerous slen- 
der lateral branches, these leafy, covered with slender spines 2 to 3.5 em. long; 
leaves oblanceolate or obovate, 1.5 to 2 em. long; flowers in large panicles 
borne at the summit of the trunk, nearly sessile, 12 to 14 mm. long; sepals 4 
mm. long, rounded; corolla 6 to 7 mm. long; stamens 10; capsule 8 to 10 mm. 
long. ‘“ Cirio.” 

This is one of the most curious and remarkable plants of Baja California, 
because of its weird appearance and strange habit of growth. It grows on 
sandy flats and rocky hills at low altitudes, and in many places is abundant, 
forming regular forests. The trunks sometimes send forth a few large erect 
branches above the middle; at the base they are often nearly a meter in di- 
ameter. The older trees frequently become topheavy and lop over, thus as- 
suming fantastic forms. The wood is soft and spongy. The trunks are often 
hollow, and sometimes inhabited by bees. For illustrations of the plant see 
Contr. U. S. Nat. Herb. 16: pl. 121, 122. 

The following account of the tree by Clavigero (Historia de la California, 
1789) is doubtless the first published descripticn of it: “Much more curious 
is another tree, called by the Cochimi milapd, which is common from the 
twenty-ninth to the thirty-first degree, and had not been seen by the mission- 
aries before the year 1751, for they had not entered that part of the country ; 
nor is it, as I believe, Known even yet among naturalists. It is so large that 
it rises perpendicularly to a height of 70 feet; its trunk, proportionately thick, 
is not woody but soft and juicy, like the branches of the pitahayo and cardén; 
its branches are certain twigs, a foot and a half long, adorned with small 
leaves and with a spine at the tip; the direction of the branches is not upward 
or horizontal, like those of most trees, but they hang down like beard from 
tip to the base of the trunk, and upon them are bunches of flowers, but no 
fruit has ever been seen. This great tree is of no use, for even when dry it 
is not good for fuel; nevertheless, in the mission of San Francisco de Borja 
they used to burn it for lack of other firewood.”

Durango to Querétaro and Hildago; type from Puente de la Madre de Dios 
(Hidalgo ?); perhaps also in Coahuila. 

Shrub or tree, 4 meters high or larger; leaves oblong-obovate or spatulate, 
2 to 8 cm. long, obtuse or rounded at apex; panicle usually narrow, the flowers 
short-pedicellate; corolla red, 10 to 14 mm. long. “ Ocotillo,’ ‘ teocotillo,” 
“albarda,” “ alabarda,” “barda” (Durango). 

It is probably this species which, according to Altamirano, is known in 
Querétaro as “chiquifia.” The pulverized seeds are used in Durango as a 
remedy for toothache, and the stems for fences and sides of huts. 

The species was described from fruiting material, and the inflorescence igs 
described and illustrated as being corymbose-paniculate. It may be, therefore, 
that the name fasciculata does not apply to the plants placed here by the 
writer. Material from Hidalgo agrees with Durango specimens upon which 
Fouquieria campanulata is based, and since no other species is represented in 
recent collections from Hidalgo, it seems probable that the names F’. fasciculata 
and F.. campanulata refer to the same species.

from the base; leaves oblanceolate to rounded-obvate, 2 to 3 em. long; panicles 
5 to 20 em. long; corolla bright red (very rarely white), 2 to 2.5 em. long. 
“Ocotillo”? (Chihuahua, Coahuila, Zacatecas, Baja California, Texas, New 
Mexico) ; ‘albarda”’ (Zaeatecas, Coahuila) ; “barda” (Coahuila). 

In the United States the plant has been called ‘“ coachwhip,” “ vine-cactus.” 
and ‘‘ Jacob’s-staff,” but the word “ ocotillo” is more generally used and is a 
better name. It is sometimes corrupted into “ ocotilla”’ and “ ochotilla.” 

This is one of the most common and characteristic plants of the desert re- 
gions of northern Mexico and the southwestern United States, growing upon 
plains and rocky hillsides. For most of the year the plants are leafless spiny 
sticks, apparently dead, but in summer when rains fall they put out their 
bright green leaves and, at the tip of the branch, dense masses of vivid red 
flowers. The leaves soon fall. The wood is heavy and resinous. The branches 
are frequently made into walking-sticks, and they are employed to make fences 
or the sides of huts. If planted in the ground they often grow and form a 
living hedge. 

The bark contains gum, resin, and wax. Palmer reports that the flowers are 
employed in Coahuila as a remedy for coughs. The Coahuilla Indians of south- 
ern California eat the flowers and seed pods, and prepare a sweet beverage by 
soaking the flowers in water.

Tree, sometimes 7 meters high, the trunk 10 to 20 em. thick, short, yellowish 
green, the branches brown, their spines 1 to 2 cm. long; leaves lanceolate to 
broadly obovate, 2 to 4 em. long, acute to rounded at apex; panicles usually

The bark is employed as a substitute for soap, especially in washing woolen 
goods.

Shrub, 2 to 3 meters high, with very short trunk; panicles 5 to 15 cm. long, 
many-flowered; corolla bright red, 2 cm. long. “Palo de Adan,” “ cirio” 
(Baja California). 

This grows with F. splendens in Baja California, but is distinguished from 
that species by the definite trunk. It is abundant there in many places, usually 
growing in sandy places. For an illustration of a plant see Contr. U. S. Nat. 
Herb. 16: pl. 120. 

The plant is mentioned first by Clavigero (Historia de la California, 1789), 
who writes of it as follows: “There is also another small tree bristling with 
long spines, and almost always naked, for which reason the Spaniards gave it

small leaves, but after a month it sheds them and remains naked all the year.”

The only other genus represented in Mexico is Lechea, of which two species 
occur. They are distinguished from Halimium by having 3 instead of 5 petals.

Plants herbaceous or suffrutescent, slender; leaves alternate, narrow, entire, 
estipulate ; flowers racemose, subumbellate, paniculate, or glomerate, all petalif- 
erous or partly cleistogamous; sepals 5, the 3 outer ones much narrower than 
the others; petals 5 in the petaliferous flowers, yellow, fugacious; stamens 
numerous; fruit a glabrous capsule, 3-valvate, many-seeded. 

The plants of this genus have usually been referred to Helianthemuwm, but 
recent writers restrict that to certain Old World plants. ‘ 

Some of the United States species are known as frostweed and rock-rose. 
They contain a volatile oil, tannin, and apparently a glucoside, having a bitter 
and astringent taste and tonic and astringent properties. Formerly they were 
employed as a remedy for diarrhea and scrofulous affections, and as a gargle 
in the treatment of scarlatina.

By Grosser this is considered a synonym of H. scoparium (Nutt.) Grosser, 
but it appears to be fairly distinct from that (California) species in its much 
larger flowers.

Besides the type collection, the writer has seen only a single specimen, one 
collected between Somoriel and Las Lajas, Sinaloa. This represents a taller, 
more strict plant, but does not appear to differ otherwise from the Chihuahua 
plant. Grosser gives aS a synonym ‘“ Cistus ciliaris Moc. in sched.,” so he must 
have seen at least one Mexican specimen besides the type, although he cites 
no other.

The arnotto tree or shrub is one of the best known of tropical American 
plants because of the yellow-red dye obtained from the fruit. This dye has long 
been employed by the aborigines and is now an article of commerce, and the 
plant is frequently cultivated. In order to obtain the coloring matter the seed 
pods are crushed and thrown in water, whereupon it is dissolved. The liquid 
is then strained, the coloring matter settles to the bottom, the water is drawn 
off, and the sediment is formed into cakes, in which form the dyestuff is 
shipped. Sometimes the fruits are placed in water and allowed to ferment, 
during which process the dyestuff separates and settles. The dye is used for 
coloring silk and cotton orange-yellow, but the color is said to be fugitive. It is 
employed extensively for coloring cheese and butter, as well as oils and varnish. 
Large quantities are imported into Europe and the United States, the supply 
coming largely from South America. In tropical America arnotto (written also 
anatto, and in various other forms) is employed for coloring food, especially 
rice, and for flavoring chocolate and other articles. By the Indians it has been 
and still is employed extensively for painting the face and body, partly for 
ornament and partly to prevent the attacks of mosquitoes and other insects. 
At an early date the plant was introduced into the Pacific islands, and the 
natives there soon learned to use the dye for painting their bodies. The color- 
ing properties of the dye are dependent upon two principles, bixin and orellin. 

The wood is described as nearly white, porous, and very soft, with a specific 
gravity of 0.399. It is of little or no use. The Indians employed it to obtain 
fire by friction. The stems, crushed and thrown in water, yield a gum some- 
what resembling gum arabic. The bark contains a strong fiber, from which 
cordage is sometimes made. 

Arnotto is much used in domestic medicine in tropical America. Astringent, 
febrifuge, antidysenteric, diuretic, aphrodisiac, and other properties are 
ascribed to it and it is employed for venereal diseases, erysipelas, intermittent 
fevers, epilepsy, and other affections. The pulp, if applied immediately to 
burns, is said to prevent the formation of blisters or scars. The leaves are 
applied as poultices to relieve headache. A decoction of them is employed as 
a gargle for sore throat. The seeds are said to be the best antidote for poison- 
ing by yuca agria or yuca brava (Manihot). 

Heckel’ states that in Madagascar, where the plant is cultivated, the Mala- 
gaches who have to speak or dance in public take an infusion of the leaves to 
make themselves bold and courageous. In Brazil the pulp of the seeds has been 
given to bulls about to appear in the ring in order to make them more lively 
and dangerous. It may be that the plant contains some excitant principle 
which has not yet been investigated. ; 

The specific name of the arnotto plant, orellana, was given in honor of Don 
Francisco Orellana, the disloyal but famous comrade of Pizarro, and discoverer 


1 Les plantes utiles de Madagascar, p. 183. 1910.

of the Amazon, who achieved one of the most remarkable explorations of maistory 
in his descent of that river from its headwaters. 

For an illustration of Bira orellana see Contr. U. S. Nat. Herb. 9: pl. 39. 

The following interesting account of the arnotto plant is given by Oviedo 
(Lib. VIII, Cap. VI), who was probably the first to describe it: “ Bira is a 
wild shrub or plant, like the others I have mentioned, but like them it is 
sometimes cultivated by the Indians. This plant or bira grows in Hispaniola 
and the other islands and in Tierra-Firme, and its about half as high again as a 
man. It has leaves like those of cotton 4nd bears capsules resembling those of 
that plant, except that outside they are covered with coarse hairs and marked 
with veins that indicate the interior partitions, and on the inside are red seeds, 
sticky like wax or more so; and from these the Indians make balls with which 
they paint their faces, mixing the dye with certain gums, and from this they 
make a fine vermilion color with which they paint the face and body in such an 
elegant fashion that they resemble the devil himself. The women do likewise 
when they hold their feasts and dances, and the men when they wish to appear 
well and when they go to war, in order to appear fierce. It is very hard to 
remove the biza until many days pass, but it is astringent and they say very 
comfortable, and even beneficial in this way, that when they are thus painted 
if they are wounded, since the paint and the blood are of the same color, the 
men are not frightened as much as they would be if they were not painted 
red, but this they attribute to the virtues of the biza. The paint, besides its 
evil appearance, has a disagreeable odor because of the gums and other things 
mixed with it.” The plant is figured and described also by Herndndez.*

When in flower this is one of the most showy of Mexican plants. The trees 
are usually quite leafless when they flower, but they are one great mass of 
showy yellow blossoms. The branches take root readily when stuck in the 
ground, and they are often planted to form hedges. The bark contains a fiber 
which is used locally for cordage. A decoction of the wood or leaves is a popu- 
lar cure for jaundice, and the flowers are employed as a remedy for chest 
affections. The wood is soft and brittle.

Tamaulipas, San Luis Potosi, Veracruz and Yucatan. Panama, the type col- 
lected between Rio Grande and Pedro Vidal, Canal Zone. 

Tree, 10 to 25 meters high, the trunk 30 to 50 cm. in diameter, the crown 
rounded, or sometimes only a shrub; bark gray and rough; leaves deciduous, 
short-petiolate, oblong to oblong-oval, 7 to 12 cm. long, acute or obtuse, rounded 
at base, pellucid-punctate, becoming glabrate above, beneath densely pilosulous 
or tomentose; pedicels in dense lateral clusters, 10 to 14 mm. long; sepals 5, 
5 to 7 mm. long, thin, greenish white; stamens about 32; disk with as many 
staminodia-like appendages as stamens; fruit a baccate capsule, subglobose, 
shallowly 3-sulcate, about 3.5 cm. in diameter, yellowish green, opening at the 
apex by 3 valves; seeds numerous. ‘“ Volatin” (San Luis Potosi). 

The wood is said to contain an abundant transparent odorless resin. This 
species is closely related to Z. laetioides A. Rich., of the West Indies, but is 
distinct in the dense pubescence of the leaves. Pittier states that it is distin- 
guished ‘by the obtuse and versatile anthers and the hairy, clavate pseudo- 
staminodes.” 'The anthers, however, are exactly alike in both species, and in 
Z. roussoviae the disk appendages are either hairy or glabrous.

12. Casearia dolichophylla Standl., sp, nov. 

Sinaloa to Chiapas; type from Picacho, Oaxaca (Purpus 7447; U. S. Nat. 
Herb. no. 877536). Nicaragua.

long, glabrate, subterete, yellow or reddish; seeds about 4, surrounded by a 
red aril. ‘‘ Chilillo” (Sinaloa). 

The writer has referred here a large number of specimens, all of which 
may not be conspecific. On the other hand, he is not altogether confident of 
the segregates of C. nitida here proposed, or of those described by Briquet. 
Some of the specimens referred to C. dolichophylla have glabrous leaves, but 
they do not appear to differ otherwise from the typical form. 

In Sinaloa the young branches are much used for making bird cages.

STANDLEY—TREES AND SHRUBS OF MEXICO. 847 


It seems remarkable that there should be no earlier name for a plant of so 
wide distribution, but the writer has been unable to find one. This species 
differs in several respects from the other American representatives of the 
genus and may belong to a distinct genus. 


DOUBTFUL GENERA. 


AZARA UMBELLATA Presl, Rel. Haenk. 2: 92. 1886. Type from the west coast 
of Mexico. The plant is probably not of this genus, but the writer has been un- 
able to place it among any of the Flacourtiaceae represented in recent Mexican 
collections. 


112. TURNERACEAE. Turnera Family. 


REFERENCE: Urban, Jahrb. Bot. Gart. Berlin 2: 1-152. 1883. 

Herbs, shrubs, or trees; leaves alternate, petiolate, simple, toothed, often 
biglandular at base; stipules small or none; flowers axillary, solitary or fascicu- 
late, often bibracteolate, perfect ; calyx 5-lobate, deciduous, the lobes imbricate; 
petals 5, inserted in the throat of the calyx tube; stamens 5, inserted on the 
calyx tube, the filaments free; styles 3; fruit a 1-celled 3-valvate capsule, many- 
seeded. 

The genus Piriqueta is represented in Mexico by one herbaceous species. 
Calyx lobes nearly free; flowers about 8 cm. long; petals appendaged. 

1. ERBLICHIA.

Oaxaca and Chiapas; reported from Tabasco. Also in Panama, the type 
locality. 

Tree, 7 to 15 meters high; leaves lanceolate, oblong-lanceolate, or oblong- 
elliptic, 6 to 18 cm. long, acute or acuminate, crenate, glabrous above, fulvous- 
pilosulous or glabrate beneath; flowers long-pedicellate; sepals linear-lanceo- 
late, subulate-tipped, pilosulous, with thin petaloid margins; petals yellow, 
about 8 cm. long and 4 cm. wide; capsule 4 em. long, oblong-ellipsoid, densely 
fulvous-pilose, the valves very thick (2.5 to 3 em.) and woody. ‘ Sanjuanero ” 
(Tabasco, Ramirez); “jarro de oro” (Oaxaca); “azuche” (Oaxaca; from 
the Nahuatl a-zochitl, “‘ water-flower,” or ‘flower like a water-jar,’’ Reko). 

When in flower this must be a remarkably showy and handsome tree. 


2. TURNERA L. Sp. Pl. 271. 1753. 


Herbs or small shrubs; leaves serrate, often biglandular at base; flowers 
axillary, usually solitary, yellow, white, or pink, the peduncle often adnate to 
the petiole; calyx tubular or campanulate, with 5 narrow lobes; petals obovate 
or spatulate, short-clawed, thin; fruit, a thin-walled capsule; seeds with a sub- 
membranaceous aril. 

Besides the species listed below, two or three herbaceous ones occur in 
Mexico. 

Flowers pedicellate, the pedicel adnate to the petiole; petiole with 2 large

Turnera velutina Presl, Rel. Haenk. 2: 44. 1836. 

Turnera alba Liebm. Ann. Sci. Nat. III. 9: 318. 1848. 

Sinaloa to Tamaulipas, Yucatan, and Chiapas. Widely distributed in tropi- 
cal America and naturalized in the Old World. : 

Plants herbaceous or fruticose, usually 30 to 60 cm. high, sometimes as much 
as 3.5 meters high; leaves petiolate, extremely variable, linear to broadly 
rhombic-ovate, serrate or dentate or subentire, densely or sparsely pilose or 
glabrous; flowers 2 to 3 em. long, white, yellow, or pink, sweet scented; capsule 
about 6 mm. long. “Clavel de oro” (Yucatéin); ‘ caléndula,”’ “ amaranto” 
(Yueatén, Dondé); ‘ Marilépez” (Oaxaca); ‘“ Maria Lépez” (Cuba, Nica- 
ragua); ‘San Juan,” “margarita de los campos,” ‘“ oreja de coyote” (Nicara- 
gua); ‘““malva” (Colombia). 

The plant is employed locally as a remedy for indigestion, for bronchitis and 
other chest affections, and as a tonic. 

The species, as treated here and by other authors, is a remarkably variable 
one, but the variations are chiefly in leaf shape and pubescence. A form with 
linear or almost linear, glabrous or glabrate leaves is T. ulmifolia angustifolia 
(Mill.) Willd. A form with broad leaves and white flowers is 7. ulmifolia alba 
(Liebm.) Rose Turnera velutina, described from Acapulco, is a form char- 
acterized by very dense and short pubescence.

Nearly throughout Mexico, chiefly on dry hillsides. Texas, West Indies, 
Central America, and South America. 

Shrub, 0.3 to 2 meters high; leaves petiolate, obling to rhombic-ovate, mostly 
1 to 2 em. long, obtuse or acute, commonly cuneate at base, coarsely crenate- 
dentate or serrate, tomentose beneath or merely pilose, often glabrate on the 
upper surface; flowers 8 to 12 mm. long, the calyx tomentose; petals yellow; 
capsule 4 to 5 mm. long. “ Damiana” (Sinaloa, Tepic, Baja California, Tamau- 
lipas); ‘‘pastorcita,’ ‘“hierba de la pastora” (Querétaro); ‘“‘hierba del 
venado”’ (San Luis Potosi, Tamaulipas); ‘‘xmisibecoc” (Yucatén, Maya); 
“oreganillo” (Santo Domingo). 

The damiana plant has an aromatic odor and pleasant taste. It contains a 
yolatile oil with a warm, bitter, camphor-like taste, also tannin. The dried 
_ twigs and leaves are imported into the United States and used in the prepara- 
tion of medicine, although they do not constitute an official drug. They prob- 
ably have only feeble tonic properties, and the aphrodisiac properties ascribed 
to them are doubtful. In Mexico the plant is often used as a substitute for 
Chinese tea and for flavoring liquors. It has a wide reputation as an aphro- 
disiac and is administered also for dysentery, malaria, syphilitic diseases, pains 
in the stomach and intestines, dyspepsia, and even paralysis. Diuretic, astrin- 
gent, tonic, expectorant, and laxative properties are ascribed to it. The plant 
was introduced into Europe about 1874 under the name damiana, and was for 
some time recommended for all kinds of renal and vesical diseases. It should 
be stated here that the name damiana is sometimes applied to other plants, 
especially to species of Jsocoma and related genera of the family Asteraceae.

PREFACE. 


The fourth installment of the Trees and Shrubs of Mexico, by 
Mr. Paul C. Standley, Associate Curator of the United States Na- 
tional Herbarium, treats the families Passifloraceae to Scrophu- 
lariaceae. Several large families are included, notably the Cac- 
taceae, of which Mexico possesses a far greater number of species 
than does any other part of the earth. Other important groups 
covered are the Myrtaceae, Melastomaceae, Asclepiadaceae, and Ver- 
benaceae, families whose Mexican representatives have received 
little systematic attention during the last 30 years or more. 

The account of the family Passifloraceae has been furnished by 
Mr. Ellsworth P. Killip, and that of the Cactaceae by Dr. N. L. 
Britton and Dr. J. N. Rose.

1. LEUCOPREMNA Standl., gen. nov. 


Only the following species is known. By most authors it has been referred 
to the genus Jacaratia, but it seems necessary to place it in a separate genus. 


1. Leucopremna mexicana (A. DC.) Standl. 

Jacaratia mexicana A. DC. in DC. Prodr. 151: 420. 1864. 

Jacaratia conica Kerber, Jahrb. Bot. Gart. Berlin 2: 282. 1883.

Vell. 1825. 

Pileus heptaphyllus Ramirez, Naturaleza II. 3: 711. 1908. 

Colima, Guerrero, Morelos, Campeche, and Yucatén; said to occur in Oax- 
aca, and probably to be found elsewhere. El Salvador; reported from Nica- 
ragua, and apparently also in Costa Rica. 

Tree, 4.5 to 12 meters high, the trunk very thick at base, tapering upward 
and dividing into few heavy branches, the twigs thick and soft, the wood very 
soft, the trunk consisting largely of pith; bark smooth, gray; leaves deciduous, 
clustered at the ends of the branchlets, the leaflets 5 to 7, obovate, acuminate, 
10 cm. long and 6 cm. wide or smaller; flowers dioecious, the staminate in 
terminal or axillary panicles, pale yellow, the corolla about 2 cm. long; 
stamens 10, free; pistillate flowers terminal, long-pedunculate, the petals 
greenish, 4 em. long; fruit 15 ecm. long or more, 8 to 10 em. thick, 5-celled, 
pendent, conic or ovoid-oblong, 5-angled, the angles often produced below into 
conelike protuberances or wings, the skin green or yellow; seeds rough, black. 
“ Bonete” (Yucatan, Campeche, Morelos) ; “ kunché” or “ kumché” (Yucatan, 
Maya); “cuaguayote” or “coahuayote” (Colima); “coalsuayote” (Guer- 
rero) ; “ orejona,” “ papaya orejona,” “ papayo montés” (Oaxaca) ; “ cuayote” 
(El Salvador). 

In outward appearance the fruit is not unlike a large green pepper of the 
bullnose type, but it varies greatly in shape, being sometimes long, narrow, and 
twisted. The flesh is sweet and reddish yellow; it is eaten cooked or as a 
salad, and is made into sweetmeats. The juice is said to have the same prop- 
erties as that of Carica papaya. ‘Kerber reports that in Colima a kind of 
tortilla is made from the starch of the trunk. The tree has been described at 
length by Ramirez,’ and illustrated with several excellent plates. It is treated 
by Hernindez under the name “ quaiuhayoth.” 

Leucopremna mexicana is abundant in extreme western Salvador, occurring 
as a characteristic tree on the arid hills near the Rio Paz, close to the Guate- 
malan frontier.

Veracruz and Chiapas, and probably elswhere; cultivated and perhaps also 
native. Central America, Colombia, and Venezuela. 

Trunk about 3.5 meters high, leafy at the top; leaves large, cordate at base, 
lobed halfway to base or less, the lobes acuminate and with remote acuminate 
teeth, glabrous; flowers inodorous, the staminate 3 to 3.5 em. long, the pistillate 
flowers of about the same size; fruit ovoid, pointed, narrowed at base, yellow, 
8 em. long or larger. “ Papayo de montafia”’ (El Salvador).

Papaya vulgaris DC. in Lam. Encyel. 5: 2. 1804. 

Carica quinqueloba Sessé & Moc. Fl. Mex. 255. 1896. 

Commonly cultivated in all the warmer parts of Mexico and wild in many 
places. Southern Florida, West Indies, and Central and South America; culti- 
vated in the tropics of the Old World. 

Trunk sometimes 9 meters high and 25 cm. in diameter, pale green, the 
woody tissue thin and porous, the pith large, the trunk with a large central 
cavity; leaves borne at the top of the trunk, 20 to 60 cm. wide, deeply 
lobed, the lobes pinnately lobed, glaucous beneath; flowers yellow, the stami- 
nate in slender panicles 10 to 30 em. long, fragrant, the corolla 2 to 3 em. long; 
pistillate flowers solitary or in 2 or 3-flowered cymes, the petals linear-lanceo- 
late, 2 to 2.5 em. long; fruit oblong or obvoid, 5 to 10cm. long or often much 
larger, pointed, yellow or orange, with thick skin, the flesh firm, sweet and in- 
sipid; seeds numerous, black, rough. 

Known generally in Spanish-speaking countries as ‘ papaya,”’! which is 
believed to be a corruption of the Carib ‘ ababai;” the English names “ papaw ” 

r “pawpaw’’? are used, also “ tree-melon,” but “papaya” is the preferable 
name. The following additional names are reported. ‘‘ Chick put,’ ‘“ put” 
(Yucatan, Maya; the former a wild form) ; “ papaya de los pajaros”’ (Yucatan, 
a wild form); “papayero” (the plant); ‘‘melén zapote” (various parts 
of Mexico; sometimes corrupted into “ mel6én chapote”); “mandn” (Argen- 
tina); “papaya montés” (a wild form); ‘“fruta bomba” (Cuba); 
“ dzoosadzahuidium ” (Oaxaca, Mixtec, Reko); “lechosa” (Porto Rico). It 
is remarkable that no Nahuatl name is known for the plant. 

The papaya is one of the best-known of tropical American fruits. The 
fruits vary greatly in shape, size, and quality; they sometimes attain a 
length of 50 cm. and a weight of 20 pounds. They resemble some forms of 
muskmelons, especially on the inside. The flesh is 2 to 5 em. thick and 
orange-yellow or deep orange. The fruit is eaten like a muskmelon or sliced 
and served with sugar and cream, made into salads, or candied; made into

which is Asimina triloba (L.) Dunal, a plant of the family Annonaceae.

preserves, pickles, jellies, pies, or sherbets; or sometimes cooked and eaten 
like a vegetable. The plants grow easily and rapidly from seeds, and they 
bear fruit almost throughout the year. A confection is sometimes made by 
boiling the flowers in syrup. 

The fruit and other parts of the plant contain an abundant milky juice 
from which an enzyme, papain, resembling animal pepsin in its digestive 
action, has been separated. This product has become an article of commerce, 
being used for the treatment of dyspepsia and related affections, and also 
for clarifying beer. The digestive properties of the juice were well known to 
the original inhabitants of tropical America, like those of to-day, who often 
wrap meat in the leaves and leave it thus over night, to make it tender. 
Sometimes leaves are boiled with meat for this purpose, but if too much 
papaya juice comes in contact with the meat, or for too long a time, the 
meat will fall apart in shreds. Indeed, it is even popularly believed that 
the plant is even more efficient, for it is said that if old hogs and poultry 
are fed on the leaves and fruit, their flesh will become tender, and if a 
piece of tough meat is hung among the leaves of the tree for a few hours 
it also will be made tender. This last property is attested by so eminent 
an authority as Heber Drury, who states that he proved it by experiment. 
The leaves are sometimes used in Mexico as a substitute for soap in washing 
clothes. 

Various medicinal properties are attributed to the papaya plant. The 
seeds and the milk from the roots are often employed as a vermicide, and 
the milk is applied to the skin to assist in the removal of chiggers. The in- 
fusion of the flowers is reported to have emmenagogue, febrifuge, and pectoral 
properties; a decoction of the leaves is employed as a remedy for asthma; 
and the juice is administered for indigestion. Grosourdy states that the juice 
of the ripe fruit was used as a cosmetic, to remove freckles. 

The papaya is treated at length by Oviedo (Lib. VIII, Cap. XX XIII), who: 
states that in Hispaniola it was known as “ papaya,” but among the Spaniards. 
of the mainland it was called “ higos de mastuerzo,” the latter name being 
given because the seeds had a pungent flavor like cress (mastuerzo). In Nica- 
ragua, he states, the plant or fruit was called ‘“ olocotén.” He claims also 
that the plants were not native in the West Indies, but were brought there by 
the Spaniards from the mainland, which may or may not be true. The plant 
is mentioned by all the early writers, and is described by Hernandez.’ 

Ramfirez has described and illustrated* a fruit known as “papaya vola- 
dora,” which is presumably a form of this species. It is noteworthy in hav- 
ing peduncles as much as 34 cm. long. The flowers of Carica papaya are usu- 
ally dioecious, but oceasionally both kinds of flowers are found upon the same: 
plant. 


DOUBTFUL SPECIES. 


CARICA BOURGAEI Solms in Mart. Fl. Bras. 133: 178. 1889. This name is used 
by Solms in his key to the species of the genus, but, so far as the writer can 
learn, no description has ever been published. The species was probably based 
upon a specimen from the Valley of Cérdoba, Veracruz, and the plant is closely 
related to C. papaya.

long, acute or attenuate, entire or with a few large remote teeth, pale beneath; 
staminate corolla 5 mm. long, the lobes as long as the tube; fruit subglobose, 
2.5 em. in diameter, with short thick appendages. “ Jarrilla,” ‘ granadilla.” 

The writer has seen only a single specimen of this species, consisting of 
staminate plants from La Palma, Jalisco.

Baja California, Sinaloa, Jalisco, and Guanajuato; type from mountains of 
Paja California. 

Plants slender, 1 meter long or less, erect or decumbent, the root large; leaves 
long-petiolate, very variable, rounded-ovate to deltoid or deltoid-oblong, 2 to 12 
cm. long, acute to rounded at apex, cuneate to cordate at base, entire, undulate, 
dentate, or lobate, pale beneath; staminate inflorescence long-pedunculate, the 
corolla purplish white, about 1 cm. long, the lobes much shorter than the tube; 
pistillate flowers usually solitary, long-pedicellate ; body of the fruit ellipsoid or 
subglobose, sometimes 9 cm. long, the elongate fleshy style 1 to 2 em. long, the 
appendages 3 to 5 cm. long; seeds surrounded by a white aril. “ Jarrilla” 
(Guanajuato, Jalisco) ; said to be known as “bonete” in Jalisco. 

The fruit has an odor resembling that of lemon or citron. It is usually 
employed for making preserves or Sweetmeats, and is well known in the 
markets of Jalisco and Guanajuato. 

The specimens which have been referred here by Ramirez and by the present 
writer are remarkably variable, and it is not improbable that they represent 
more than a single species. The writer has seen only six collections, and they 
are quite inadequate for critical study. It is desirable that a large series of 
specimens be collected of these plants, which are practically unknown outside 
the limited area within which they grow.

Usually herbs but sometimes shrubs; leaves opposite or alternate, entire or 
toothed, estipulate; flowers perfect, racemose or cymose-paniculate, the pedi- 
cels bibracteolate; calyx tube adnate to the ovary, the limb 4 or 5-lobate; petals 
4 or 5, inserted in the calyx throat; stamens few or numerous; style subulate, 
entire or bifid or trifid; fruit a 1-celled capsule, containing 1 to many seeds. 

Several other genera are represented in Mexico by herbaceous species. Some 
of them are plants with stinging hairs. Cevallia sinuata Lag..is a common 
plant of the desert regions of northern Mexico, with hairs which sting as pain- 
fully as those of a nettle.

Several other representatives of the genus occur in Mexico, but they are 
herbs. The leaves in most species of this genus are extremely scabrous and 
cling tenaciously to clothing. Some of the species are knowa in the United 
States by the name of “stickleaf.”

Cactaceae of northeastern and central Mexico, Ann. Rep. Smiths. Inst. 1908: 
525-563. pl. 1-15. 1909. 

Plants perennial, succulent, usually shrublike or treelike; leaves usually 
none or much reduced, sometimes large and flat; spines present, variable in 
form and arrangement, borne upon areoles in the leaf axils; flowers usually 
perfect, regular or irregular, solitary or clustered, sometimes borne in a 
terminal specialized inflorescence known as cephalium; perianth tube none 
or large and elongate, with few or numerous lobes, these sometimes differ- 
entiated into sepals and petals; stamens commonly numerous, the filaments 
usually borne upon the throat of the perianth, the anthers small, 2-celled; 
style one, terminal, the stigma with 2 to many lobes; ovary 1-celled; fruit 
baceate, fleshy or dry, usually containing numerous seeds. 

The Cactaceae constitute one of the largest and most interesting groups 
of Mexican plants, and they are more profusely developed in Mexico than 
in any other part of the earth. They are often conspicious features of the 
landscape, particularly in the desert regions, and they are of great economic 
importance. Many of the more showy ones are commonly grown in gardens 
for ornament.

linear; seeds black, glossy, with a brittle shell, the embryo strongly curved, 
the cotyledons leafy; seedlings without spines. 

Pereskia portulacifolia (L.) Haw. has often been reported incorrectly from 
Mexico. The following vernacular names have been given for it: “ Pitahayita 
de agua” (Jalisco) ; “pata de leén,” “patilon” (Oaxaca). The name “palo 
de puerco espino” is reported from Oaxaca’ for a Pereskia whose specific 
identity is doubtful.

Cultivated throughout tropical America; perhaps an escape in Mexico. 

Shrub, at first erect, but the branches often clambering and forming vines 
3 to 10 meters long; spines on lower part of stem solitary or 2 or 3 together, 
slender and straight; spines in the axils of the leaves paired, rarely in threes, 
short, recurved; leaves short-petioled, lanceolate to oblong or ovate, short- 
acuminate, tapering or rounded at base, 7 cm. long or less; flowers in panicles 
or corymbs, white, pale yellow, or pinkish, 2.5 to 4.5 em. broad; ovary leafy 
and often spiny; fruit light yellow, 1.5 to 2 em. in diameter, when mature 
quite smooth; seeds black, somewhat flattened, 4 to 5 mm. in diameter. ‘“Gro- 
sellero”’ (Cuba). 

This species is often cultivated, the flowers being handsome, although they 
have an offensive odor. The fruit is edible, and is sometimes used for making 
preserves. The leaves are said to be employed in Brazil as a pot herb. In 
the British West Indies the plant is sometimes known as Barbados goose- 
berry or Spanish gooseberry.

Nopalea cochenillifera is one of the best known of Mexican plants, particu- 
larly because of the fact, as indicated by the specific name, that it was upon 
this cactus that there were propagated the cochineal insects from which was ob- 
tained the famous dye of the same name. The source of the dye was well 
known to the precolumbian inhabitants of Mexico, who used it for coloring va- 
rious articles. Immediately after the Conquest the export of cochineal was 
begun, and it was long one of the chief articles of tribute to the crown. The 
industry was later established in Spain, India, Jamaica, the Canary Islands, and 
elsewhere. The principal producer of the dye was probably the Canaries, and 
from those islands in 1868 more than 6,000,000 pounds, valued at $4,000,000 
was exported. With the development of coal-tar dyes this industry quickly de- 
cayed. 

The cochineal insects were “ planted” upon the branches of the plants, where 
they quickly multiplied, and were later brushed off into bags. After hav- 
ing been dried, they became the cochineal of commerce. Large plantations of 
Nopalea plants were made in Mexico for this purpose, the chief centers of 
production being in Guerrero and Oaxaca. It should be noted that the 
eochineal insect lives upon Opuntias, and extends as far north as the State 
of Colorado. 

The fruit is edible. The joints are sometimes applied as poultices to relieve 
articular rheumatism, erysipelas, ophthalmia, earache, and toothache.

areoles axillary, bearing spines, barbed bristles (glochids), hairs, flowers, and

The species of Opuntia are common in nearly all parts of Mexico, par- 
ticularly in the arid regions. Those of the subgenus Platyopuntia are of 
great economic importance because of their edible fruits. Not all species 
produce edible fruits, but in certain ones the fruits are large and of excel- 
lent quality. During their season the tunas are the principal food of the 
people in certain parts of Mexico, and enormous quantities of them are con- 
sumed. Usually they are eaten raw, but they are also cooked in various 
Ways, and sweetmeats are made from them. Queso de tuna consists of the 
dried fruit pressed into large cakes; this is widely sold in the markets. 
Miel de tuna is a syrup prepared from the fruit. Melcocha is a thick 
paste made by boiling down the juice. Colonche is the boiled and fermented 
juice. Nochote or nochocle is a fermented beverage prepared from tuna juice, 
pulque, and water.1 Tejuino also is a beverage prepared from the juice 
of the fruit. 

The tender young joints are often cooked as a vegetable. They are also 
applied as poultices to reduce inflammation. The juice of the joints is 
sometimes boiled with tallow in making candles, in order to make the 
candles hard. 

Among some of the Californian Indians the seeds were an important food. 
These were stored until winter, when they were ground and used to pre- 
pare a kind of atole. 

Many of the Opuntias are of importance as food for stock in the arid 
regions. In order to make them more easily edible, the spines are some- 
times burned off with torches.2 

The usual name for a plant of the subgenus Platyopuntia is “ nopal’’; 
for the fruit “tuna” (a name said to be of West Indian origin). The English 
name is prickly pear. An infinite number of names is employed in Mexico 
to designate the numerous varieties of the fruit that are recognized. The 
following are some of the names that are reported for the plants and their 
fruits: SsNoechtliv2. (ruit. Nahuatl): “culhua”’:> “pacae”, —‘“potzotzi”” 
(Huastec) ; “taat” (Mixe); “pare” (Tarascan) ; “ c&ihi” (fruit), ‘ xatha” 
{plant) (Otomi). 

The nopal occupies a prominent place in Mexican legend and history, and 
upon the national banner there appears an eagle perched upon a nopal plant. 

The tunas are mentioned by all the early writers, as, for instance, Oviedo, 
who devotes a long chapter to them. 3ernal Diaz del Castillo mentions 
them as one of the fruits depended upon for food during the siege of Mexico

southwestern United States. 

Usually bushy, often compact, 2 meters high or less, but sometimes with a 
short definite trunk 5 to 8 cm. in diameter, dull green with darker blotches 
below the areoles, with slender, cylindric, ascending, hardly tuberculate 
branches; branches, especially the fruiting ones, thickly set with short, usu- 
ally spineless joints spreading nearly at right angles to the main branches, 
very easily detached; spines usually solitary at young areoles, very slender, 
white, at areoles of old branches 2 or 3 together, 2 to 5 cm. long or less: are- 
oles with very short white wool; flowers greenish or yellowish, 1.5 to 2 em. 
long (including the ovary); ovary obconic, bearing numerous small woolly 
brown areoles subtended by small leaves, its glochids brown; fruit globular 
to obovate or even clavate, often proliferous, red or rarely yellow, 10 to 18 
mm. long, slightly fleshy. ‘‘ Tasajillo” (Durango, Nuevo Leén, Tamaulipas, 
Chihuahua, Texas, New Mexico). 

The plant is abundant in many parts of northern Mexico and often forms 
dense thickets. The long spines are very offensive, and often cause bad sores 
when they penetrate the flesh. 

Opuntia ramosissima Engelm.,’ a closely related species, common in south- 
western Arizona, should be looked for in Sonora and Baja California. 

Opuntia tesajo Engelm.’? was based on a Baja California specimen, but the 
type has been lost, and the plant should perhaps be referred to O. leptocaulis.

Treelike, often 3 meters high or larger, with a more or less definite woody © 
trunk 25 cm. in diameter; ultimate joints 2 to 3 cm. in diameter, strongly 
tuberculate; tubercles 2 to 2.5 em. long, flattened laterally; spines 8 to 30,

tuberculate, bearing a few bristles from some of the upper areoles; fruit 
naked, yellow, 2.5 to 3 em. long, strongly tuberculate or, when long persistent, 
smooth; seeds 2.5 to 3.5 mm. in diameter. ‘“ Xoconochtli” (Herndndez) ; 
“xoconostle,” ‘joconoxtle” (Jalisco); ‘“ joconostle” (Zacatecas); “ car- 
denche” (Durango, Zacatecas) ; ‘‘ tasajo”’ (Chihuahua) ; “ coyonostle’’ (Nuevo

“tuna joconoxtia” (Jalisco); “tuna huell” (Griffiths); “velas de coyote,” 
“entrana’’ (New Mexico). 

In many parts of its range this is an abundant and characteristic plant- 
often forming extensive thickets. In early times a decoction of the fruit was 
used to set cochineal dye, and it is said to be so employed even at the present 
time. The stems contain a hard woody framework resembling a network after 
the soft tissue has been removed, and they are often made into canes. Among 
the Penitentes, a religious organization of the Southwest, it was formerly 
the custom, among other similar practices, during Holy Week to march in 
processions with large bundles of the very spiny stems bound upon their 
naked backs. 

The Pimas of Arizona formerly consumed quantities of the hard fruits of 2 
related species. These were cooked over night in pits filled with heated stones, 
then dried in the sun, after which the spines were removed, and the fruit stored 
for later use. Thus prepared, the fruit was boiled and salted and eaten with 
pinole, or it was cooked with meat or various herbs. 

Opuntia cardenche Griffiths? is perhaps a synonym of this species, or possibly 
referable to O. kleiniae.

-This is one of the cacti most cultivated in northern hothouses, where it 
is known as “old man cactus.” The young plants are densely covered with 
long white hairs. The species is very abundant on the limestone hills of 
eastern Hidalgo, where it is often the most conspicuous plant.

seeds together into a kind of flour which is used for making tamales. For 
illustrations of this species see Contr. U. S. Nat. Herb. 16: pl. 130, 181, 182. 
It is probably this plant which is described by Clavigero (Historia de la 
California, 1789) under the name “card6n.” Among other notes, he remarks 
that “the missionaries found a method of utilizing the branches, for from a 
piece about two palms long they extracted by crushing the juice, which they 
boiled down, thus obtaining a balsam which is good for wounds and bruises.”

the honey which they contain. This species, like many other cacti of similar 
habit, is-much planted to form living fences. The straight trunks are placed 
closely side by side and form impenetrable barriers, which are characteristic 
features of Mexican towns.

tetetzo Weber; Schum. Gesamtb. Kakt. 175. 1897. Described from Jalisco. 
This species has been referred to the present group, but the ovary is glabrous, 
and the fruit fleshy and edible. It should be compared with Cephalocereus 
macrocephalus. The names “tetetzo,”’ “tetazo,” ‘cabeza de viejo,” and 
“tetecho” are reported for it. The fruits, known as “higos de tetetzo,” are 
edible, and are sometimes preserved by drying, and the flowers are said to be 
eaten in salads.

Plants usually large, tall, and branching, but rarely low, nearly prostrate, 
simple, forming thickets; areoles rather large, felted; spines usually stout and 
numerous; flowers diurnal or in some species nocturnal, one at an areole, tubu- 
lar-funnelform or campanulate, the short tube tardily separating with the style 
from top of the ovary; stamens numerous, borne in many rows all along the 
inner surface of the throat; ovary more or less tubercled, bearing scales felted 
in the axils, the areoles at first spineless or nearly so, soon developing a

gathered in large quantities, and sweetmeats are sometimes made from it. 
For an illustration of the plant see Contr. U. S. Nat. Herb. 16: pl. 125, A. 

It is doubtless this species of which Clavigero (Historia de la California, 
1789) writes as follows: “ Nowhere is the pitahayo so luxuriant as in Cali- 
fornia * * * Underneath the bark there is about a finger’s breadth of 
green and very juicy pulp, and within that a woody tube full of whitish pith 
which, when dry, burns well and is used for torches for giving light. Toward 
the ends of the branches spring forth beautiful white flowers, spotted with 
bright red, but without odor, and these are followed by the fruits, called 
pitahayas by the Spaniards, and tammid or dammidé by the Cochimi of Cali- 


STANDLEY—TREES AND SHRUBS OF MEXICO. 901 


fornia. This fruit is round, of the size of a large peach, and is also armed 
with spines; at first it is green, but when ripe it turns red or yellow. That 
with red rind has pulp of a beautiful blood-red color, and that with yellow 
rind has white or yellow pulp. The rind is rather thick but soft and easily 
’ separated, and the pulp is sweet, mild, refrigerant, and wholesome. After 
the rind is removed the pulp is eaten, along with the seeds, with which it is 
filled, which are somewhat like those of the fig, although smaller. The red 
pitahayas color the urine like blood, for which reason some strangers who 
have eaten them have been much alarmed, thinking that they have broken 
a blood vessel. In the southern part of the peninsula the harvest of the sweet 
pitahayas begins the first of June, and ends the last of August; in the northern 
part it begins later and is most abundant in August; but when there is a 
little more rain than usual the harvest is very scant or none at all, for there 
is no plant so much injured by dampness as the pitahayo. For harvesting, 
the Californians use a stick to one end of which is firmly attached a slender 
hook-shaped bone, for pulling off the fruit, and a net in which to catch it 
without letting it fall on the ground. After it is gathered, they take off the 
spines with a little stick, which is easily done if the fruit is ripe, and then they 
peel and eat it; and in this way they go about gathering and eating until 
filled, and what is left they take home. During the time of the harvest the 
people go all day long over the mountains and plains hunting for ripe pitahayas, 
and for them, as we shall see later, this is the happiest season of the year.”

Baja California and on the adjacent islands. 

Erect or ascending, but usually not a meter high, or with long, spreading, 
sometimes prostrate branches, the whole plant sometimes having a spread of 
6 to 7 meters; branches 4 to 6 cm. in diameter; ribs usually 8, rarely 9, low 
and obtuse; areoles rather large, about 2 em. apart; spines stout, the radials 
8 to 12, somewhat unequal, about 1 cm. long; central spines 3 to 6, stout, 
flattened, one much longer than the others and about 4 cm. long; flowers 10 
to 14 cm. long, the tube long and slender; inner perianth segments 2 to 2.5 em. 
long, purple; fruit subglobose, 6 to 8 cm. in diameter, spiny; skin of fruit 
bright scarlet; pulp purple; seeds rugose, pitted, 2.5 mm. long. ‘“ Pitahaya,” 
“nitahaya agria.” 

The fruit is agreeably acid, and is much eaten. The crushed stems are 
sometimes thrown in water to stupefy fish. For an illustration of the plant see 
Contr. U. 8S. Nat. Herb. 16: pl. 126A. 

It is apparently of this species that Clavigero writes as follows: ‘“ After 
the harvest of the sweet pitahaya [Lemaireocereus thurberi] follows that

of the sour one, called tajudé by the Cochimi, and this lasts through Septem- 
ber and October or, if the season is favorable, even into November. ‘The 
branches of this plant also are ridged, spiny, and without leaves, but the 
ridges are more ordinary and the spines larger, denser, and stouter. The 
branches are straight and parallel like those of the tammid or sweet pitahayo; 
but from the trunk they take different directions, without any order or 
symmetry and, stretching over the ground, they throw out roots and form 
new plants; interlacing with each other, there result thickets which are 
unpleasant to look at and impenetrable by animals. The plant differs from 
the first kind also in the places in which it grows; for that fruits well 
anywhere in the mountains or on the plains, provided it is dry, while this is 
found only on the p!ains near the coast, and if plants are found occasionally 
in the mountains they are always sterile.”

This is the state flower of Arizona. It is a very abundant and conspicuous 
plant in the southern part of that State and in northern Sonora.*’ The dried 
woody ribs of the stems were used by the Indians for lances and for the frame- 
work of huts. The fruit was an important article of food among all the 
Indians of the region. It was eaten raw or cooked and was sometimes dried 
and preserved for winter use. From it, there was prepared a thick syrup 
which was employed for sweetening other food, and also an intoxicating 
beverage. The seeds contain much oil, and by the Papagos they were ground 
into a paste which was spread like butter upon tortillas. They were also 
eaten raw or ground and made into pinole. The seeds were sometimes collected 
and eaten after having passed through the body, a practice that was followed 
also by some of the Californian Indians in the case of Opuntia seeds.

This species has often been reported from Mexico as Cereus triangularis 
(a species known only from Jamaica) and as C. trigonus. The large fruit is of 
excellent quality and is much eaten. Grosourdy reports that the juice of the 
stems is acrid and caustic and is employed externally and internally as a 
vermicide, although internal use is dangerous. The plant is the best known 
of all the night-blooming cereuses, and produces very showy flowers.

“Organillo” (Tamaulipas); “reina de la noche”; “gigante’” (Durango) ; 
“reina de las flores” (Porto Rico). 

This is a well-known night-blooming cereus, often cultivated for its hand- 
some fragrant flowers. The fruit is edible. The flowers and stems contain 
several acrid principles,-including probably an alkaloid and a glucoside, to 
one of which the name cactine has been given. The drug obtained from the 
plant has an action similar to that of digitalis, and is used also in the treat- 
ment of rheumatism.

ribs 7 to 13, nearly vertical or irregular and indistinct, tubercled; flowers cen- 

tral, each surrounded by a mass of long hair, in color pale pink to white, 

2.5 em. broad when fully open, with a broad funnelform tube; outer perianth 

segments nearly white; style white below, pinkish above, shorter than the 

perianth segments; stigma lobes 5, linear, pinkish; ovary naked; fruit 2 cm. 


long or less; seeds 1 em. in diameter, with a broad basal hilum. ‘“ Peyote”; 
“hikuli” (Huichol and Tarahumare) ; ‘“kamaba” (Tepehuane, Ochoterena) ; 
““sefif,’ “ wokowi” (Querétaro, Ramtrez). 


This is a well-known plant in Mexico, and an account of it was published by 
Sahagtin in the sixteenth century. The peyote contains a narcotic substance 
that has been the subject of much study with regard to its chemical and phy- 
siological properties. The name anhalonin has been given to a supposed alka- 
loid separated from the plant, but other persons claim that the narcotic prop- 
erties are due to the presence of certain resinous bodies. 

The dried plants have been in use among the native people since precolum- 
bian times, and are still employed, although their use is forbidden by law. 
Hating a piece of the dried plant results in remarkable visions and hallucina- 
tions, and the general effects are somewhat like those resulting from the use of 
hashish.”

33. FEROCACTUS Britt. & Rose, Cactaceae 3: 123. 1922. 


Globular to cylindric, often large cacti; ribs thick and prominent; spines 
well developed, either straight or hooked; areoles usually large, bearing flowers 
only when young and then only just above the spine clusters, more or less 
felted when young; flowers usually large, broadly funnel-shaped to campanu- 
late, usually with a very short tube; stamens numerous, borne on the throat, 
short; ovary and flower tube very scaly; scales naked in their axils; fruit 
oblong, usually thick-walled and dry, dehiscing by a large basai pore; seeds 
black, pitted, never tuberculate; embryo curved. 

Besides the species here listed, one other is known, a native of the south- 
western United States. The species of Ferocactus are well known in the arid 
regions of Mexico and the United States because of their large size and abund- 
ance, and the varied uses made of them. In the United States they are usu- 
ally known by the name barrel cactus. By the Indians they were sometimes 
employed as cooking vessels, the interior being scooped out and mashed, and 
the water thus obtained being replaced in the cavity and heated with hot 
stones, after which meat and other substances were placed in the liquid and 
cooked. » The liquid obtained by crushing the pulp has sometimes been used 
as a substitute for water in the desert. The pulp is often fed to horses and 
cattle. 

The candied pulp makes an excellent sweetmeat, which is much used in 
Mexico and the southwestern United States, and is often sold in the eastern 
United States as “cactus candy.” The Papago Indians of Arizona are re- 
ported to have prepared a sweetmeat by boiling the pulp in the syrup of 
Carnegiea gigantea. 

The usual Mexican name for plants of the genus is “ biznaga’” or “ viz- 
naga.” The name biznaga is applied in Spain to the parsnip (Pastinaca sativa), 
and the word is of Arabic origin. The Mexican word, however, is believed to 
have been derived from the Nahuatl, huitzli, spine, and nahuac, around, i. e., 
covered with spines. Concerning these plants Robelo’* writes as follows: “It 
is well known that the Mexicans in their bloody and gloomy religion performed 
the rite of sacrificing their flesh, drawing blood from the ears, thighs, arms, 
and legs, nose, and even the tongue. For such sacrifices they employed the 
spines of the biznaga and metl [maguey]; and these objects being consecrated 
or even deified, the biznaga founded a cult, which was personified by a deity, 
Huitznahuatl, to whom was erected a temple, Huitznahua-teapan, and to the 
place where the spines were kept was given the name Huitzcalco.” The Mexi- 
cans also used the name feocomitl, ‘divine vessel,” for the plants; while 
Hernindez mentions the “ comitl,” ‘“ tepenexcomitl,” and “hueycomitl,” all of 
which probably belong to this genus. The biznaga was sacred to the god Mix- 
coatl. 

Buelna reports the Otomi name as “pe,” and the name “ caballufia” is re- 
ported for an unidentified species. 

Clavigero gives a description of one one of the species of Ferocactus occuring 
in Baja California, and says: ‘In New Spain some people use the spines for 


1Anal. Mus. Nac. II. 2: 375. 1905. 


STANDLEY—TREES AND SHRUBS OF MEXICO. 941 


toothpicks, and in some of the missions of California they employed them for 
knitting stockings, straightening out the tips and reducing the thicker part. 
Among these spines the viznaga produces its handsome flowers, tinged with 
white, red, and yellow, which are followed by the fruit, much smaller than 
that of the tammid, and full, like that of the cardén, with viscous juice and 
seeds, which latter the Californians eat, after preparing them like those of the 
cardén. In Mexico they make a good sweetmeat from the juicy pulp 
of the viznaga.” Clavigero also makes the following shrewd statement, which 
indicates that he had no mean knowledge of plants: ‘“ It is certainly wonder- 
ful that the plants of which I have spoken, and others of which I shall speak 
later, have more juice in arid places than other kinds of trees have in humid 
regions; but it is still more remarkable that they maintain themselves with- 
out any deterioration with little or no dew, although it may not rain for 10 
months or more, as often happens in California. I believe that these plants are 
more juicy because they transpire less, inasmuch as they have no leaves, for 
these, as is the fundamental belief of physicists, are the principal organs of 
tranpiration among plants: it may be conjectured that the Creator denied 
these plants leaves because He destined them to inhabit dry lands.”

sometimes all alike, sometimes with central ones very different from the 
radial, all straight or sometimes one or more of the central spines hooked; 
flowers, so far as known, diurnal, from axils of the old tubercles, much 
alike as to size and shape, more or less campanulate, comparatively small.

Oaxaca. Central and South America. 

Shrub or small tree, 1 to 6 meters high, covered everywhere with dotlike 
black glands; leaves opposite, nearly sessile, elliptic-lanceolate, 3 to 10 em. 
long, acute or acuminate, puberulent beneath; flowers yellow, in short dense 
axillary cymes, 4 or 5-parted; calyx broadly turbinate, 3 to 4 mm. long, not 
appendaged; petals slightly exserted; stamens 7 to 12. ‘“ Chaparral” 
(Colombia) ; “ guayabito” (Venezuela). 

The sapwood is said to be light cream-colored or nearly white, the heartwcod 
light yellow, turning darker or reddish on exposure, moderately soft and 
light, very fine-grained, and taking a good polish. 


2. PARSONSIA Adans. Fam. Pl. 2: 234. 1768. 


Shrubs or herbs; leaves opposite or ternate; flowers 6-parted, racemose or 
lateral, the pedicels axillary or interpetiolar; calyx tubular, often spurred at 
base; petals 6, 2, or none; stamens 11 or 9; ovary with a dorsal or cupuliform 
disk at base; fruit capsular, 1-celled, dehiscent along one side; seeds few or 
numerous. 

Numerous herbaceous species occur in Mexico. Many of those listed below 
do not merit classification as shrubs, but others are truly woody. Some of the 
Brazilian species are reported to have sudorific, antisyphilitic, and diaphoretic 
properties. P. petiolata (L.) Rusby, of the United States, is said to resemble 
digitalis in its physiological action.

5. LAWSONIA L. Sp. Pl. 349. 1753. 


The genus consists of a single species. 


1, Lawsonia inermis L. Sp. Pl. 349. 1753. 

Lawsonia. alba Lam. Encycl. 3: 106. 1789. 

Cultivated in many parts of Mexico, and in places growing without cultiva- 
tion. Native probably of Africa and Asia, but commonly cultivated in most 
tropical and subtropical regions. 

Shrub or tree, 2 to 6 meters high, glabrous, the branchlets often spinelike; 
leaves opposite, oblong or obovate, 1 to 2.5 em. long, mucronate-acuminate, 
narrowed at base; flowers 4-parted, in large open terminal panicles, sweet- 
seented; calyx broadly turbinate, 3 to 5 mm. long; petals yellow, reniform, 
nearly sessile; stamens 8; fruit globose, 2 to 4-celled, indehiscent. ‘‘ Reseda” 
(Sinaloa, Tamaulipas, El Salvador, Nicaragua, Costa Rica, Colombia, Porto 
Rico) ; ‘ cinamomo” (Philippines). 

The henna plant is cultivated in tropical America for its sweet-scente/l 
flowers. It grows readily from cuttings and makes a good hedge plant, some- 
what resembling privet. The odor of the flowers is strong and resembles that 
of mignonette. The leaves of henna are much used in the Orient for stain- 
ing the nails, hands, and feet yellow, and also for dyeing the hair and beard. 
A paste of the leaves applied to the hair or beard soon produces a bright red 
color, which is considered becoming among certain classes of Mohammedans. 
Frequently, however, an indigo paste is next applied, and this turns the hair 
jet black. The tails and manes of horses are sometimes colored red in the 
same way. From the flowers is obtained a perfume which becomes an in- 
gredient of oils and ointments, and was employed by the Egyptians in em- 
balming; also by the Jews in baths and in religious ceremonies (it is the 
“camphire” of Solomon). The plant yields a dull red dye for cloth. The 
fruit is reputed to have emmenagogue properties and the leaves are used in- 
ternally and externally for jaundice, leprosy, and various cutaneous affections.

1026 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


Shrub, 0.5 to 3 meters high, glabrous; leaves mostly opposite, sessile, linear- 
lanceolate or lanceolate, 2 to 9 em. long, acuminate; flowers yellow, inodorous, 
pedicellate, solitary in the axils; calyx campanulate, 5 to 9 mm. long, with 
hornlike appendages at base of lobes; petals 5 to 7, 12 to 17 mm. long; 
stamens 10 to 18. ‘“ Hauchinal,” ‘“ hauchinol,’ ‘“ hauchinoli,” ‘ hachinal,”

“sinicuil’’ (Nuevo Leon, Jalisco); “ granadillo” (Urbina); ‘“escobilla det 
rio”’ (Tamaulipas) ; “ quiebra yugo,” “ quiebra arado” (Argentina, Uruguay). 

The petals fall soon after the flowers open. The plant is much used locally 
in medicine, emetic, antisyphilitic, hemostatic, febrifuge, diuretic, laxative, 
vulnerary, sudorific, tonic and astringent properties being ascribed to it. It 
is employed most commonly for syphilitic affections. The leaves are said 
to contain 9 per cent of a bitter principle, nesine, and about 14 per cent of 
a resin, the latter being the active principle. If the juice or a decoction 
of the plant is taken internally it is said to produce a mild and pleasant 
intoxication, during which all objects seen appear to be yellow. Palmer 
reports that in Tamaulipas a decoction of the plant is employed as a wash 
to relieve the effects of poison ivy (Rhus toxicodendron). 

This plant was listed by Sessé and Mocifio’ as “ Ginora [Ginoria] americana,” 
a name pertaining to a Cuban plant of a different genus. It is described also 
by Hernandez.’

Crape-myrtle is an extremely handsome plant, with very showy and hand- 
some flowers which are borne in great profusion and for most of the year. 
Although it grows well in the tropics, it is not a tropical plant, but can stand 
considerable freezing. In the United States it is hardy as far north as 
Baltimore, and is grown out of doors still farther north.

ovary 3 or 4-celled. 


119. PUNICACEAE. Pomegranate Family. 


The family consists of a single genus and species. 


1. PUNICA L. Sp. Pl. 472. 1753. 


The generic name is derived from the Latin name for the Carthaginians 
(Punici), who are said to have introduced the pomegranate into Italy. 


1. Punica granatum L. Sp. Pl. 472. 1753. 

Common in cultivation nearly throughout Mexico. Native of the Mediter- 
ranean region, but cultivated everywhere in warm countries. 

Shrub or small tree, 6 meters high or less, sometimes with a short trunk, 
the bark very thin, brownish gray, shallowly reticulate; leaves opposite or 
clustered, short-petiolate, elliptic, oblong, or oblanceolate, 2 to 6 em. long, 
obtuse, attenuate at base, entire, glabrous; flowers perfect, short-pedicellate, 
solitary or clustered; calyx leathery, 5 to 7-lobate, the lobes triangular; petals 
5 to 7, obovate to suborbicular, 1.5 to 2.5 cm. long, bright red; stamens nu- 
merous; fruit a leathery berry, globose, 5 to 10 cm. in diameter, several- 
celled; seeds numerous, surrounded by white or pink, acidulous pulp; wood 
hard, close-grained, light yellow, its specific gravity about 0.98. The plant is 
known everywhere in Spanish-speaking countries as ‘“ granado,” the fruit 
as “ granada”; the following names also are reported: “ Tzapyan,” “ tzapyon ” 
(Mixe, Belmar) ; “ yaga-zehi”’ (Oaxaca, Zapotec, Reko) ; ‘ yutnu-didzi” (Oax- 
aca, Mixtec, Reko). 

The pomegranate is cultivated in the southern United States and is hardy 
as far north as the city of Washington. It is one of the best of the tropical 
fruits, being one of the few that are acidulous, most tropical fruits being 
sweet or insipid. It is a favorite fruit in Mexico, where numerous varieties 
are grown, such as the “granada de China,” “granada agria,” and others. 
The principal variation is in the size of the fruit and the color of the pulp. 
The pomegranates of Tehuacin, Puebla, are famous for their quality. The 
fruit is eaten without special preparation, or is made into sherbets and bever- 
ages. 

The hard wood is sometimes used by engravers as a substitute for box- 
wood (Buxrus sempervirens). The bark and the rind of the fruit are astrin- 
gent, and are employed for tanning and dyeing leather. The bark, with iron 
sulphate, gives a black ink, and the flowers with alum a red ink. 

The bark of the stem and root is official in the United States Pharmacopoeia, 
its active power being due to an alkaloid, pelletierine. The bark contains 
over 22 per cent of tannic acid. The bark is employed as a vermifuge and 
teniafuge, being particularly efficient for the latter purpose. It is used locally 
also for dysentery and intermittent fevers and as a gargle for sore throat. 


120. RHIZOPHORACEAE. Mangrove Family. 


1. RHIZOPHORA L. Sp. Pl. 448. 1753. 
The genus consists of about three species, widely distributed on tropical 
coasts. 


1. Rhizophora mangle L. Sp. Pl. 448. 1758. 
Common along both Mexican coasts from Tamaulipas and southern Baja 
California southward. Widely distributed in tropical America.

(Veracruz, Colima, Sinaloa, Ramirez) ; ‘mangle salado” (Panama) ; ‘‘ mangle 
zapatero” (Porto Rico); “mangle gateador”’ (Costa Rica). 

The mangrove (sometimes known as “red mangrove’’) is the most abundant 
and conspicuous tree of tropical coasts, forming dense forests or thickets of 
great extent almost everywhere that the water is brackish. The plants send 
out numerous arching prop roots in all directions, which are covered at 
high tide, and these form impenetrable tangles. The roots are often covered 
with oysters. The mangrove is important in land building, preventing wash- 
ing away of land by waves and also affording a place of protection for soil 
and refuse. Thus small islands gradually increase greatly in size. The soil 
underneath mangrove trees usually consists of black oozy mud, and the man- 
grove forests are extremely repellent in appearance when seen at close hand, 
although when viewed from a distance they are strikingly handsome. 

The wood is used for fuel and for building wharfs and docks, since it is 
durable in water and is not attacked by the mollusk Teredo. Clavigero states 
that it was employed for making oars, and Oviedo states that “it is one of 
the best woods there is here (West Indies) for the poles of huts and timbers 
of houses, and for door and window frames.’ The leaves and especially 
the bark are rich in tannin and the latter is used for tanning leather. The 
bark, with salts of copper or iron, yields olive, brown, and slate dyes. Of 
the fruit, Oviedo (Lib. IX, Cap. VI) states that it “is tawny and within 
is a marrow or heart which the Indians eat when they can find no better 
fruit (for it is somewhat bitter), and they say it is wholesome.” The bark 
has been employed as a febrifuge and to stop hemorrhages, also as a remedy 
for sore throat. Pittier reports that in Panama a red dye is obtained from the 
young shoots.

1. CONOCARPUS L. Sp. Pl. 176. 1758. 
A single species is known. 


1. Conocarpus erecta L. Sp. Pl. 176. 1753. 

On both coasts of Mexico, from Tamaulipas and southern Baja California 
southward. Widely distributed on tropical American shores and in western 
Africa. 

Variable in size, sometimes a prostrate shrub but usually erect, becoming a 
tree 20 meters high, with a trunk 80 cm. in diameter; bark dark brown, fis- 
‘sured into irregular ridges and thin scales; leaves alternate, short-petiolate, 
obovate to elliptic or oval, 2 to 10 em. long, obtuse or acute at each end, en- 
tire, leathery, glabrous or sericeous, the petiole bearing 2 glands; flowers per- 
fect, very small, green, in globose paniculate heads 1 cm. or less in diameter ; 
ealyx 2 mm. long; cerolla none; stamens usually 5, exserted; fruit a conelike 
head of small flat winged scalelike drupes, purplish green; wood hard, close- 
grained, grayish or yellowish brown, its specific gravity nearly 1.00. ‘“ Mangle 
negro” (Oaxaca); “xtabché” or “xkanché” (Yucatan, Maya); “ estacha- 
huite” (from the Nahuatl istac-cuahuitl, “ white-tree,’ referring to the whit-

“mangle pifuelo” (Panama); “yana” (Cuba); “ mariquito” (Costa Rica) ; 
“mangle torcido”’ (Panama). 

The buttonwood grows in mangrove swamps with the mangroves and 
Avicennia nitida. The wood ‘s used for rafters, boats, cabinet work, and 
various other purposes; it is said to be durable in the soil. The leaves and 
bark are employed for tanning skins. The bitter bark finds use locally in 
medicine as an astringent and tonic. : 

Conocarpus erecta sericea DC. is a form with densely sericeous leaves. It 
occurs on both coasts of Mexico with the typical glabrate form. By some 
authors it has been considered a distinct species, but it grades gradually into 
the common form. 


2. TERMINALIA L. Mant. Pl. 1: 21. 1771.

1. Terminalia catappa L. Mant. Pl. 2: 519. 1771. 

Cultivated in Mexico and perhaps naturalized; specimens seen from Sinaloa, 
Tepic, Guerrero, Oaxaca, and Yucatin. Native of the Hast Indies, but gen- 
erally cultivated in trépical regions. 

Large tree, sometimes 25 meters high, with a trunk 1.5 meters in diameter, 
the branches whorled, spreading; leaves obovate, 10 to 30 cm. long, rounded 
and abruptly pointed at apex, narrowed to the base, nearly glabrous; spikes 
5 to 15 em. long, the pistillate below; fruit a woody drupe, ellipsoid or 
rounded, 4 to 7 em. long, compressed, 2-edged ; seed 3 to 4 cm. long; wood hard, 
close-grained, red-brown, the specific gravity about 0.70. ‘‘ Almendra” (fruit), 
“almendro” (tree), “‘almendron” (Yucatén, Guerrero, Oaxaca, Porto Rico, 
Costa Rica, Philippines, El Salvador, Santo Domingo); “ almendrillo’” 
(Oaxaca) ; “almendra de la India” (Cuba, El Salvador). 

The wood of the Indian almond is a valuable source of lumber when pro- 
curable in sufficient quantity. The roots, bark, and fruit contain much tannin, 
and are employed for tanning skins. The fruit and other parts furnish a 
permanent black ink and dye, and in India the fruit is employed to color 
the teeth black. Silkworms are fed upon the leaves. The seeds contain about 
50 per cent of a fixed oil. They are edible and are used like almonds; in flavor 
they suggest filberts. The plant is sometimes used locally in medicine because 
of its astringent and supposed tonic properties. For illustrations of this 
species see Contr. U. S. Nat. Herb. 8: f. 13, pl. 57. 


2. Terminalia excelsa Liebm. (Hemsl. Biol. Centr. Amer. Bot. 1: 402. 1880, 
nomen nudum). 

Veracruz. 

Tree; leaves obovate, obtuse or acute, attenuate at base to a slender petiole, 
thinly sericeous when young but soon glabrate; racemes lax, 8 to 10 em. long, 
finely fulvous-tomentulose ; calyx lobes short, rounded or very obtuse; stamens 
long-exerted, the filaments glabrous; style 3 to 4 mm. long, glabrous; very 
young fruit thinly fulvous-tomentulose. 

No description of this species has been published, apparently. Presumably 
it was based upon specimens collected at Mirador by Liebmann. The writer 
has seen a single flowering specimen, with immature leaves, from Zacuapan 
(Purpus 3800), which is probably of the same species. It appears distinct 
from either of the species recently described from Panama. 

According to Ramirez, the tree is known in Veracruz as “ pucté.” 


3. BUCIDA L. Syst. Nat. ed. 10. 2: 1025. 1759. 


The genus consists of a single species. 


1. Bucida buceras L. Syst. Nat. ed. 10. 1025. 1759. 

Campeche; reported from Tabasco. Southern Florida, West Indies, and 
Panama. 

Tree, sometimes 25 meters high, with a trunk 90 em. in diameter, the crown 
broad and spreading; bark gray, scaly; branches often armed with spines 
2 to 3 em. long; leaves alternate but crowded at the ends of the branches, 
petiolate, obovate, oval, or elliptic, 3 to 9 em. long, rounded or retuse at apex, 
entire, coriaceous, sparsely sericeous when young; flowers perfect, green, in 
slender spikes; calyx 3 mm. long, sericeous; petals none; stamens 10, ex- 
-serted; fruit a drupe, ovoid, 7 to 8 mm. long; wood hard, close-grained, yel- 
lowish brown, its specific gravity about 1.04. ‘ Puk-té” or “pue-té” (Cam- 
peche, Tabasco) ; “ ficar,”’ “ bicaro” (Porto Rico) ; ‘“ jicaro de playa” (Cuba). 

The tree is said to be abundant in some parts of the Yucataén Peninsula, 
and to be a valuable source of lumber. The wood is very durable and is em-

ployed for posts, piling, axles, wheel hubs, and other purposes. The bark 
is employed for tanning. For an illustration of a tree see Contr. U. S. Nat.

Conocarpus racemosa L. Syst. Nat. ed. 10. 930. 1759. 

Coasts of Tamaulipas and Yucatin. Southern Florida, West Indies, Pan- 
ama, South America, and western Africa. 

Shrub or tree, sometimes 20 meters high, with a trunk 80 em. in diameter; 
bark thin, reddish brown, fissured into long scales; leaves opposite, petiolate, 
oblong to oval, 2 to 7 cm. long, rounded at apex, entire, leathery, glabrous, the 
petiole with 2 large glands; flowers perfect or polygamous, in lax clustered 
spikes; calyx 5-lobate, sericeous, 2 to 3 mm. long; petals 5, suborbicular, not 
exceeding the calyx; stamens 10; fruit a leathery 10-ribbed reddish drupe, 
oblong or obovoid, 15 mm. long; wood hard, strong, dense, yellowish brown, 
its specific gravity about 0.86. ‘‘ Mangle blanco” (Tamaulipas, Sinaloa, Pan- 
ama, Porto Rico) ; ‘mangle amarillo,” ‘“ patabin’ (Cuba); “mangle prieto ” 
(Santo Domingo) ; “mangle chino” (Sinaloa). 

The white mangrove (known also as “ white buttonwood’”’) is usually asso- 
ciated with Rhizophora mangle, Conocarpus erecta, and Avicennia nitida. 
The bark contains about 14 per cent of tannin, and is used for tanning skins. 
It is employed locally in medicine as an astringent and tonic. For an illus- 
tration of the flowers see Contr. U. S. Nat. Herb. 8: pl. 43.

Sinaloa to Chiapas and Veracruz; type collected between Acapulco and 
Venta del Ejido, Guerrero. Guatemala and El Salvador. 

Large vine, unarmed; leaves broadly oval to elliptic-oblong, 5 to 15 cm. 
long, obtuse or short-acuminate, sparsely or densely lepidote beneath; spikes 
very thick and dense, solitary or paniculate; flowers blood-red or green- 
ish yellow, sweet-scented ; calyx limb often 1 cm. long; petals oblong-spatulate 
to broadly ovate, 1.5 to 2 mm. long, obtuse or acute; fruit about 2 cm. long, 
lepidote. ‘‘Carape” or “carapi’ (Michoacin, Guerrero) “ peinetillas” (the 
spikes), “compio” (Sinaloa); “ angarilla” (Durango, Patoni) ; ‘ peinecillo” 
(Veracruz) ; “ quie-tzine’”’ (Oaxaca, Seler) ; “ abacamiel,” “abamiel” (Central 
America) ; “ papa-miel” (Nicragua) ; “ chupamiel,” “ peineta,” “ chupamiel de 
peineta,” “ chupa-chupa ” (El Salvador). 

The branches were formerly used for arrow shafts and are now sometimes 
woven into baskets. The showy flowers are full of sweet nectar. When cut, 
the stems yield a considerable amount of water, a fact of which advantage is 
taken by travelers through the forests when other water is absent. In Sinaloa 
the leaves are applied as a remedy for headache. 

In a recent account of the species of Combretum of the section Micropetalae’, 
Pittier has treated C. argenteum as a valid species, distinguished from C farino- 
sum chiefly by its broader petals. Examination of the available material shows 
that there is too great variation in petal shape to admit of its use as a basis 
of specific segregation. 


122. MYRTACEAE. Myrtle Family. 


Trees or shrubs, usually aromatic; leaves entire, opposite, pellucid-punctate 
or gland-dotted, estipulate; flowers perfect, regular, variously arranged, bi- 
bracteolate; calyx tube adnate to the ovary, the limb 4 or 5-lobate, or the lobes 
united in bud and sometimes circumscissile; petals 4 or 5 or none; stamens 
numerous; ovary 2 to several-celled, the style simple, the stigma capitate; 
fruit baccate or drupaceous, large or small, containing 1 to many Seeds. 

This is one of the large families in tropical America, and its representatives 
are easily recognized by the combination of punctate leaves, numerous stamens, 
and characteristic fruit. It is, however, almost impossible to distinguish the 
genera by the embryo characters upon which they are based, and it is extremely 
difficult to identify a plant of the family except by comparison with named 
specimens. 

Several species of the Australian genus Hucalyptus are grown in Mexico for 
ornament. They are known as “eucalipto” and “ gigante.” Eucalyptus trees 
grow rapidly, and for this reason they are planted in Florida and California as 
shade trees and as a source of lumber. As shade trees, however, they are not 
desirable, for their foliage is so thin and their crowns so narrow that they

afford little shade, while their roots spread in every direction, making it im- 
possible to grow other plants in their vicinity. They are not particularly 
handsome trees, and their only good feature is rapidity of growth.

Mitranthes sartoriana Berg, Linnaea 29: 248. 1857. 

Tepic to Oaxaca, Veracruz, and Yucatin; type from Mirador, Veracruz. 

Shrub or tree, sometimes 15 meters high, the bark gray, smooth; leaves petio- 
late, ovate or broadly ovate, acuminate or abruptly acuminate, obtuse or acute 
at base, glabrous, the lateral nerves obsolete or nearly so; peduncles axillary, 
slender, 1-flowered, 1 to 1.5 cm. long; buds glabrous; fruit subglobose, 1.2 to 2 
em. in diameter, greenish yellow, containing several seeds. ‘‘ Pichiché” (Yuca- 
tan, Maya); “arrayén” (Jalisco, Veracruz, Oaxaca, Durango) ; ‘‘ guayabillo” 
(Guerrero, El] Salvador). 

This tree is often planted for its fruit and as an ornamental tree. The 
fruit is juicy and has a rich spicy subacid flavor. It is employed chiefly in 
making refreshing drinks, and is used either fresh or dried. The bark is em- 
ployed for tanning, and the leaves are reputed to have tonic and astringent 
properties. 

This species has been mentioned in literature as Myrius arrayan H. B. K., 
an error for which Sereno Watson’ seems to have been responsible. He had 
little ground for such an identification, except the fact that the vernacular 
name “‘arrayin” was applied to both species. Myrtus arrayan is a Peruvian 
species, and Watson evidently believed that it had been introduced into Mexico 
from South America. Some Mexican writers have been so ignorant of the sig- 
nificance of the name array4n that they have suggested that it might be of 
Carib origin. It is, however, the name applied in Spain to one of the forms of 
Myrtus communis, consequently it is not surprising to find it applied in widely 
separated localities of America to other Myrtaceous plants.

Widely distributed in Mexico, in the southern part probably native, but in 
places probably only naturalized; frequent in cultivation. Southern Florida, 
West Indies, and Central and South America; cultivated in the Old World 
and in many places thoroughly naturalized. 

Shrub or tree, sometimes § meters high, with a trunk 30 cm. in diameter; 
bark scaly, reddish; branchlets quadrangular, tomentulose; leaves short-petio- 
late, 5 to 15 cm. long, acute or obtuse, the upper surface tomentulose when 
young but soon glabrate, the lateral nerves very conspicuous beneath; pe- 
duncles 1 to 3-flowered; buds tomentulose or glabrate; petals 4 or 5, white, 
1.5 to 2 em. long; fruit globose or pyriform, 3 to 6 cm. in diameter, yellow 
or pinkish; wood hard, strong, elastic, close-grained, brownish or reddish 
gray, its specific gravity about 0.69. Known generally as “guayaba” (the 
fruit) and “ guayabo,”’ words of Antillean origin. The following additional 
names are reported, some of chem relating to horticultural varieties: “ Jalo- 
cote” (from the Nahuatl zal-rocotl, sand sour fruit) ; “ guayabo de venado” 
(Colima; a wild form) ; “pichi” (Yucatan, Maya); “guayaba de China”; 
“ouayaba colorada’; “ guayaba peruana”’; “ guayaba perulera” (form with 
pyriform fruit); “guayaba de gusano” (Nicaragua); “ guayaba manzano” 
(Colombia) ; ‘‘ posh,” “ posh-keip” (Mixe, Belmar; former the fruit, latter 
the plant); “enandi” (Tarascan, Ledédn); “poos,”’ “ poos-cuy” (fruit and 
tree; Zoque, Gonzales) ; “ bayabas” (Philippines, a Tagalog corruption of the 
word guayaba). 

The name Psidiwm pomiferwn relates to the form with globose fruit; 
P. pyriferum to that with pyriform fruit. 

The guava is one of the most widely known of tropical fruits, and by 
many persons it is highly esteemed. The fruit varies greatly in size; the 
flesh is whitish, yellowish, or pink, full of large seeds, of Sweetish or some- 
what acid flavor. It has a remarkably strong, musky odor, which is penetrat- 
ing and persistent. The fruit is rather insipid when raw, and it is more 
commonly eaten cooked, stewed or made into jelly, paste, preserves, and 
confections. Guava jelly, particularly, is a noted delicacy. Another species, 
P. cattleianum Sabine, the strawberry guava, a native of Brazil, with glabrous 
leaves, bears superior fruit, in flavor suggesting a strawberry. It is grown 
in the United States and perhaps also in parts of Mexico. 

In the warmer parts of Mexico and Central America guava bushes orten form 
dense thickets of considerable extent, which are known as “ guayabales.” The 
seeds germinate readily, and are spread largely by domestic animals. The 
plants possess great vitality and behave like weeds. Many Mexican localities 
are noted for the guavas produced there, and the term “ Guayabero” is some- 
times applied to thé natives of Cuernavaca, because of the abundance of 
guavas in the vicinity. 

The wood is said to take a good polish and to be durable when in contact 
with the soil, but the trees are usually too small for use. The bark is some- 
times employed for tanning. A decoction of the buds is a local remedy in 
Mexico for diarrhea; the leaves are reputed to be a remedy for itch; and 
a decoction of the astringent bark is applied to ulcers and taken internally 
for pains in the stomach. 

Guavas are mentioned by all the early writers, as, for instance, Hernindez* 
and Acosta. The latter writer, with his customary pessimism, says: “It is 


* Thesaurus 84-85. 1651. 


STANDLEY—TREES AND SHRUBS OF MEXICO. 1037 


a tree which is held in low esteem on the mainland and in the islands, for 


they say it smells like bugs. The flavor of the fruit is very ordinary and the 
flesh unwholesome.”

Sinaloa to Veracruz and Chiapas. Central America, the type from Guate- 
mala. 

Shrub or small tree, often less than a meter high; leaves petiolate, variable 
in form, obovate-oblong to elliptic or rounded-obovate, 5 to 12 em. long or 
larger, rounded at apex or acute, usually narrowed to the base, tomentulose 
above when young but later glabrate, brownish-tomentose beneath, the pu- 
bescence sometimes scant in age; peduncles 1 to 3-flowered; buds usually 
tomentose, sometimes giabrate; petals white, about 1 cm. long; fruit globose, 
about 2.5 cm. in diameter, pale yellow, with whitish pulp. ‘“‘ Guayaba agria” 
(Jalisco) ; “ giiisaro” (Costa Rica) ; ‘‘ guayabillo” (El Salvador). 

The fruit is very acid and not particularly agreeable. The specimens re- 
ferred here are variable in leaf characters, and it is not improbable that they 
represent two or more species. On the other hand, it is doubtful whether 
P. molie is distinct from P. araca Raddi, a Brazilian species. Some of the 
Mexican and Central American material has been referred to the latter.

Tree, 9 to 12 meters high, the branchlets quadrangular; leaves petiolate, 
oblong to Oval-oblong, 9 to 20 cm. long, rounded or obtuse at apex, obtuse or 
acute at base, coriaceous, when young sparsely puberulent but soon glabrous; 
flowers in short, axillary or subterminal cymes, sericeous; buds about 2 mm. 
jong; sepals 4, minute; petals 4, rounded; fruit baccate, 1 or 2-celled, 1 or 2- 
seeded, globose, 4 to 8 mm. in diameter. ‘‘ Pimiento” (Oaxaca); “ pimienta 
gorda” (Tabasco, Oaxaca, El Salvador, Guatemala) ; “ pimienta de Tabasco” 
(Tabasco, Oaxaca); ‘“pimentén” (Tabasco); ‘ xocoxochitl” (Nahuatl) ; 
“malagueta” (Tabasco); ‘pimiento oloroso” (Nicaragua); ‘“ Jamaica ” 
(Costa Rica). 

It is this tree which furnishes the allspice of commerce, and the tree is 
culvated for this reason, chiefly in Jamaica. Allspice is the unripe fruit, 
dried in the sun. The ripe fruit is blackish brown and very odorous. It 
contains an essential oil. The fruit is used in domestic medicine as a stimu- 
lant, and it is said to be smoked like tobacco in some regions. The leaves, 
either fresh or dried, have a strong, spicy, very agreeable odor. The tree 
is described by Hernandez.

5. MYRTUS L. Sp. Pl. 471. 17583. 


Shrubs or trees; peduncles usually axillary and 1-flowered, with 2 bractlets 
at apex; flowers 4 or 5-parted; calyx tube turbinate, the lobes imbricate; 
petals spreading; fruit baccate, containing 1 or 2 or several seeds. 

The Mexican species are difficult to distinguish from those of Hugenia, but 
ihe Mexican representatives of the latter genus usually have larger leaves 
and fasciculate flowers. The common myrtle of southern Europe and 
western Asia, Myrtus communis L. (‘“mirto’) is said to be cultivated oe- 
casionally in Mexico. Wreaths of its branches were worn by the Athenian 
magistrates and by victors in the Olympic games.

1. Myrtus oaxacana Standl., sp. nov. 

Type collected between Juchitén and Chivela, Oaxaca (Nelson 2631; U. 8S. 
Nat. Herb. no. 566319). 

Branches terete, grayish, glabrous, densely leafy; leaves short-petiolate, 
oblong-linear or lance-linear, 14 to 40 mm. long, 2 to 4 mm. wide, obtuse, 
acute at base, glabrous, densely gland-dotted, the lateral nerves evident, the 
margins thickened; flowers partly fasciculate in the axils and partly in few- 
flowered racemes, the pedicels slender, 3 to 5 mm. long; bractlets minute; 
calyx 1 to 15 mm. long, glabrous, gland-dotted, the 4 lobes semiorbicular, 
shorter than the tube; petals glabrous, eciliate, 2.5 mm. long. 

The plant is very unlike the other Mexican species of the genus, and it is 
not at all certain that it is properly referable to Myrtus. In general appear- 
ance, however, it bears more resemblance to some of the South American 
species of this genus than to any other Myrtaceous plant seen by the writer.

Smith, a species occurring in Guatemala, which is probably not distinct from 
M. montana. The latter name, however, is the older one.

Shrubs or trees; inflorescence racemose, cymose, corymbose, or fasciculate, 
or the flowers rarely solitary; calyx tube globose or turbinate, the limb usually 
4-lobate, the lcbes imbricate, commonly suborbicular; petals 4, spreading, 
white; ovary 2-celled; fruit drupaceous or baccate, containing 1 or few seeds. 

This is the largest genus of the family Myrtaceae, including probably 500 
species in tropical America. The species are most abundant in the West Indies 
and South America. In Mexico and Central America there are comparatively 
few species, but it is likely that the number will be greatly increased by 
further exploration. Probably the number represented among the Mexican 
collections available for study is greater than in the following list. Several 
plants of which specimens have been seen probably belong to distinct species, 
but it is not advisable to attempt to describe them until more ample material 
has been collected. 

The fruit of most of the species is edible, but the amount of flesh is usually 
seant, and the seeds large. Hugenia unifiora L., the Surinam cherry, known 
in Brazil as “ pitanga,” is cultivated in Florida, the West Indies, and South 
America for its edible fruit. This is as much as 2.5 em. in diameter, deep 
crimson, juicy, and of good flavor. It is known in Cuba as “ cerezo de Cayena ” 
and in El Salvador as “ guinda.”

Cultivated in Guerrero, Veracruz, Tabasco, and doubtless elsewhere; prob- 
ably naturalized locally. Native of southeastern Asia and Australia, but wide- 
ly cultivated and naturalized in tropical regions. 

Glabrous tree, 6 to 9 meters high; leaves short-petiolate, narrowly lanceolate, 
12 to 20 em. long, long-attenuate, coriaceous; flowers greenish white, sweet- 
scented, in few-flowered terminal cymes, the petals 1.5 to 2 em. long; stamens 
very numerous, 3 to 4 em. long; fruit pyriform or subglobose, 3 to 5 em. thick, 
white or yellowish, tinged with pink. ‘“‘Pomarosa” (Veracruz, Oaxaca, El 
Salvador, Guerrero, Porto Rico) ; ‘“manzana rosa” (El Salvador). 

The rose-apple is cultivated for its fruit, which is fragrant like roses. The 
fruit is sweet and insipid; it is used locally for making preserves and con- 
fectionery. In some parts of the American tropics the tree has become thor- 
‘oughly naturalized. In Porto Rico the branches are employed for hoops of 
sugar casks and for coarse baskets. The pulverized seeds are employed in 
Hl Salvador as a remedy for diabetes, and the wood is used for fuel. The 
tree is a handsome one for ornamental planting.

ones filiform-pedicellate; calyx about 3 mm. broad, the lobes rounded, ciliate; 
fruit globose, 6 to 8 mm. long, 1-seeded. “ Yagalan” (Oaxaca, Reko). 

Galeotti 2882 and 2887 from Oaxaca belong here, also Palmer 148 from 
San Luis Potosi, and probably Rovirosa 510 from Tabasco. The specimens 
from eastern Mexico have wider leaves than those from Guerrero and Oaxaca, 
but probably all are conspecific. Upon the same plant some of the flowers 
are solitary and others cymose. The fruit is said to be edible.

truncate, lobed, or calyptriform; petals as many as the calyx lobes, inserted 
on the limb of the calyx; stamens as many or twice as many as the petals; 
style simple, the stigma capitate or punctiform; fruit baccate or capsular, 2 to 
many-celled. 

One of the largest families of American plants, in Mexico confined chiefly 
to the truly tropical, and generally humid portions of the southern states. 
Since nearly all the Mexican representatives of the family are woody, it has 
seemed advisable to include in the present treatment the herbaceous species 
as well. 

One class of terms used in describing the nervation of the leaves in this 
family should be explained here: Three-nerved or 5-nerved leaves are those in 
which all the nerves arise from the base of the blade; triplinerved or quintupli- 
nerved leaves are those in which the lateral nerves have their origin above the 
base of the blade.

“mora” (Tepic); “pupu” (Sinaloa); “capulin de cotorro,’ ‘“ tecapulin,” 
“teshuate” (Veracruz). 

Judging from the number of herbarium specimens at hand, this is by far 
the most common Melastomaceous plant of Mexico. The form with narrow 
leaves is C. lanceolata Cogn.* and C. minutiflora Rose, but it grades imper- 
ceptibly into the typical form. Some specimens of C. zalapensis exhibit a 
truly remarkable diversity in leaf pubescence. Some of the leaves are, when 
young, finely tomentose upon the upper surface, and these leaves, even in 
age, are densely tomentose beneath. Other leaves upon the same branch are 
thinly setose upon the upper surface, without any trace of tomentum, while 
the lower surface is green and soon glabrate. Unless one had seen both 
kinds of leaves upon the same specimen, it would be hard to believe that they 
belonged to the same species. 

The dark blue or purple fruits are edible and of good flavor. They some- 
what resemble blueberries (Vaccinium) in appearance and are often seen in 
the markets of Central America.

Dry hillsides, Baja California and the adjacent islands; type from Cedros 
Island. . 

Shrub, 0.5 to 1.5 meters high, the branches brown, puberulent when young; 
leaves alternate, short-petiolate, lanceolate or oblong, 8 to 15 mm. long, en- 
tire, puberulent, gland-tipped ; flowers racemose, 2 to 2.5 em. long, bright red; 
calyx lobes about half as long as the tube; petals red, 5 mm. long; capsule 
10 to 12 mm. long, 4-celled. 

The shrub is abundant in some localities, forming small thickets. The 
racemes vary greatly in length, some of them consisting of only two or three 
flowers and others of as many as a hundred. After fruiting the racemes some- 
times. develop terminal leafy shoots. 


8. FUCHSIA L. Sp. Pl. 1191. 1753. 


Shrubs or small trees; leaves mostly opposite or verticillate, entire or den- 
tate; flowers small or large, pink, red, or purple, perfect or unisexual, axillary, 
racemose, or paniculate; calyx tube short or elongate, the limb 4-lobate; 
petals 4; stamens 8; fruit baccate, 4-celled, few or many-seeded. 

Most of the cultivated fuchsias are of South American origin, and some of 
the South American ones are grown in Mexican gardens, where they are 
known as “arete,” “Adelaida,” “ flor de arete,” “ aretillo,” “ fusia,” or “ flusia.” 
The fruits are edible, and those of F. splendens are said to be used in 
Guatemala for preserves. Some of the species are reported to have tonic, 
astringent, and febrifuge properties.

125. ARALIACEAE. Ginseng Family. 


Shrubs or trees, rarely herbs, sometimes epiphytic, the pubescence, if any, 
chiefly of branched hairs; leaves alternate, simple or compound, stipulate; 
flowers perfect or unisexual, umbellate or capitate, small, greenish; calyx 
tube adnate to the ovary, the limb short, truncate or dentate; petals usually 
5; stamens as many as the petals; styles as many as the ovary cells; fruit 
baceate, containing 2 to 7 1-seeded nutlets. 

One of the best-known plants of the family is ginseng, Panar quinquefolium 
l., a native of the United States. The fleshy roots are exported to China, 
where they are highly valued for their supposed medicinal virtues, and the 
plant has been cultivated rather extensively in the United States to obtain 
the roots for export.

Shrub, 1 to 2.5 meters high, with brown branches; leaves (except the upper- 
most) bipinnate, the leaflets oblong-ovate to broadly ovate, 2 to 5 em. long, 
acuminate, rounded or shallowly cordate at base, serrate or crenate, coarsely 
pubescent ; umbels numerous, paniculate; fruit 4 to 5 mm. in diameter, 5-sulcate.

base, densely and coarsely pubescent; umbels numerous, racemose-paniculate ; 
petals 2 mm. long; fruit about 5 mm. in diameter; styles united to form a 
slender beak. ‘ Cuajilotillo” (Sinaloa). 

It is not certain that the plant described here is the one described by De 
Candolle as Aralia pubescens, but it is a species quite distinct from 4A. 
humilis. Aralia pubescens may be a synonym of A. humilis. 


5. Aralia racemosa L. Sp. Pl. 273. 1753. 

Mountains of Chihuahua and Durango. Widely distributed in the United 
States and Canada. 

Plants herbaceous or sometimes woody, 1 to 2 meters high; leaflets broadly 
ovate, 5 to 15 em. long, abruptly acuminate, rounded or cordate at base, thin, 
sharply serrate, the teeth cuspidate-apiculate; umbels numerous, racemose- 
paniculate; fruit 5 to 6 mm. in diameter, dark purple. 

In the United States the plant is known as “American spikenard.” The 
roots are fragrant and have an aromatic sweetish flavor. They have been 
much used medicinally, chiefly in domestic practice, for their gently stimulant. 
diaphoretic, and alterative action, particularly in rheumatic, syphilitic, and 
cutaneous affections. In their properties they resemble sarsaparilla.

The rather ample material available exhibits notable diversity in size and 
shape of leaflets and size of heads, and it may be that more than a single 
species is represented. Much more material is necessary, however, before this 
ean be determined, and it seems probable to the writer that all the specimens 
represent a single variable species. O. taubertianuwm is a form with serrate 
leaflets, O. loesenerianum is noteworthy for the small staminate heads, which 
are only 5 mm. in diameter.

The wood is said to be fibrous, rather heavy, yellow, with reddish heartwood. 
It is little used except for fuel. The leaves are employed in Tamaulipas as 
a remedy for fever. 

The writer has seen no authentic material of Marchal’s species, but the 
descriptions do not suggest any important differences. Gilibertia populifolia 
was made the type of a new subgenus because of its 6-parted (rather than 
5-parted) flowers, but the flowers of G. arborea appear to be variable in the 
number of their parts.

The bark is very bitter and is said to contain an active principle, garryine. 
It is much used in Mexico as a remedy for diarrhoea. 

This species is slightly variable, and several varieties are recognized by 
Wangerin, but none of them appear to be of systematic importance. One col- 
lection reported from Chihuahua by Wangerin as G. ovata lindheimeri (Torr.) 
Coult. & Evans is referable to G. lawrifolia.

The red-osier dogwood is common along streams in the United States, espe- 
cially in the West. The branches were often employed by the Indians in mak- 
ing baskets. This is one of the plants to which the name kinnikinnick has 
been given, the leaves and inner bark having been smoked, either alone or 
mixed with tobacco, by the Indians.

The bark is employed locally as a tonic and astringent. Palmer reports that 
in San Luis Potosi the tough branches are used for fastening down the roofs 
of houses. 

This species was reported by Sessé and Mocifio as @. alba. 


8. Cornus urbiniana Rose, Contr. U. S. Nat. Herb. 8: 53. 1903. 

Cornus florida urbiniana Wang. in Engl. Pflanzenreich IV. 229: 87. 1910. 

Veracruz; type from Cerro de San Cristébal, near Orizaba. 

Large shrub or small tree; leaves ovate-elliptic, 7 to 14 cm. long, acuminate, 
glabrate above, pale beneath and sericeous-strigillose; flower heads peduncu- 
late, the bracts white and petal-like, oblong or narrowly obovate, 5 cm. long or 
less; fruit red. ‘“‘ Corona de Montezuma,” “corona de San Pedro.” 

This is very closely related to C. florida L., the flowering dogwood, one of the 
handsomest trees of the United States. The Mexican plant differs chiefly in 
its narrower bracts, and it is doubtful whether it is more than a mere form of 
Cornus florida, under which name it was reported by Hemsley. 

Cornus florida, as found in the United States, is a tree, sometimes 15 meters 
high, with hard, tough, close-grained, red-brown wood, with a specific gravity of 
about 0.81. The wood is much used for wheel hubs, tool handles, and other 
articles, and has been used as a source of charcoal for gunpowder. The bark is 
reputed to be tonic, astringent, and febrifuge, and was formerly employed in 
the southern states as a substitute for quinine. The berries were used in the 
same way. From the roots the Indians obtained a scarlet dye. The flowering 
dogwood is frequently cultivated. The most showy form is Cornus florida 
rubra Rehder, in which the bracts are red or pink,

Cornus floccosa Wang. Repert. Nov. Sp. Fedde 6: 101. 1908. 

Tepic to Zacatecas, Mexico, Morelos, and Oaxaca. Central America. 

Shrub or small tree; leaves lanceolate or oblong-elliptic, 6 to 15 cm. long, 
acute or acuminate, acute at base, pale beneath and sericeous-strigillose or 
tomentulose; flower heads pedunculate, 12 to 25-flowered; petals whitish, 3 
to 3.5 mm. long; fruit ellipsoid, 12 to 14 mm. long, purplish. “ Xochilcorona ” 
(Michoacin, Veracruz, Oaxaca). 

Cornus floccosa is a form in which the leaves are floccose-villosulous be- 
neath, while in the typical form all the hairs are straight and closely ap- 
pressed. The extremes appear distinct, but there are intermediate forms, 
and in some specimens in the National Herbarium both forms of pubescence 
occur upon separate leaves of the same branch.

This is very closely related to X. ferruginea (Walt.) Heller (Andromeda 
ferruginea Walt.), of the southern United States, and has been referred to 
that species by Hemsley and others. The Mexican plant differs only in its 
slightly shorter capsules and it is doubtful whether it represents a distinct 
species. 


4, GAULTHERIA L. Sp. Pl. 395. 1753. 


Shrubs; leaves alternate, persistent, usually toothed; flowers racemose or 
paniculate; calyx persistent, the lobes longer than the tube; corolla campanu- 
late or urceolate, with 5 spreading or recurved lobes; stamens 10, the anthers 
2-awned, opening by terminal pores; fruit berry-like, fleshy, the capsule inclosed 
in the accrescent calyx. 

Gaultheria procumbens L., of the United States and Canada, is the winter- 
green or checkerberry, from which wintergreen oil is obtained. The fruits of 
some of the species are edible. 

The names “ajocopaque,”’ “ axocopaque,” and “axocaponi” are applied in 
southern Mexico to various species. The leaves are aromatic, and Hernindez 
relates that they were used for flavoring chocolate and other beverages, and 
that they were laid among clothing to impart an agreeable odor and to keep 
away insects. The branches are even now employed as perfume in churches. 
The plants are said to have diuretic and laxative properties, and are used in 
domestic medicine.

This and other related species are known upon the Pacific Coast as ‘‘ manza- 
nita.” The fruit is edible, having an agreeable acid flavor, but it is dry, 
mealy, and full of seeds. It was an important article of food among the 
California Indians, being eaten fresh, or dried and ground and stirred into 
water to form pinole, or cooked as a mush. Death from intestinal stoppage 
is said to have resulted from eating too much of the raw fruit. Manzanita 
cider is sometimes made by scalding the ripe fruit until the seeds are soft, 
then crushing it and straining the resultant liquid, which is allowed to stand 
and settle. The beverage so obtained is spicy and acid. It is sometimes 
made from the dried berries. The leaves of the various species were smoked 
by the Indians.

The fruit is often eaten by people, and it is a favorite food of bear. It is 
often sold in the markets. Both the fruit and leaves are reputed to have 
astringent and diuretic properties, and they are employed as a remedy for 
dropsy, bronchitis, venereal diseases, and other affections. 


6. ARBUTUS L. Sp. Pl. 395. 1753. 


Shrubs or trees, the bark smooth, thin, peeling off in sheets; leaves alternate, 
persistent, petiolate, entire or serrate; flowers white or pink, in terminal 
panicles; calyx 5-lobate; corolla urceolate, with 5 small lobes; stamens 10, 
the anthers 2-awned; fruit baccate, globose, granular, 5-celled. 

The Mexican plants of this genus are extremely variable and seem not to 
possess a single constant character. It appears probable that ultimately all 
of them will have to be considered mere forms of A. ralapensis. No confidence 
ean be placed in the characters used in the following key. Of the species 
listed, the one most clearly distinct from A. xvalapensis is A. glandulosa, but 
even the characters by which it can be recognized are far from constant. 

Arbutus unedo L., a European species, has been erroneously reported in 
certain Mexican publications.

Sonora to Veracruz and Chiapas; type from Sonora. Guatemala. 

Shrub or small tree, usually 1 to 4 meters high, with very dense crown, the 
bark gray; leaves linear-lanceolate to elliptic-oblong or linear-oblong, 3 to 6 
em. long, acute, subsessile, rigid; flowers reddish yellow, about 7 mm.- long, in 
short racemes; fruit 1.5 to 2 em. in diameter. ‘“‘San Juan” (Sinaloa); “ San 
Juanito,” “San Juanico” (Sonora); “pinicua” (Sonora, Ramirez); “ rosa- 
dilla” (Oaxaca); “ mata-peje,” ‘‘luruche”’ (Guatemala) 

McGee states that the Seri Indians of Sonora eat the green fruits, and when 
dry they employ them as rattle beads. The flowers, which are stiff and rigid, 
are strung as necklaces in some localities, and they are used to give a durable 
yellow dye to palm leaves and baskets. The fruit is much used along the 
west coast for stupefying fish.

The flowers are said to be eaten by birds. Palmer reports that in Guerrero 
the powdered bark is mixed with salt and applied to sores upon animals. The 
erushed fruit is employed extensively in Mexico and Central America for 
poisoning fish. 

The tree is described and figired by Hernéndez! as “ hoitzxochitl,” or “ arbor 
lonchifolia.” ‘The bark, he states, was employed as a remedy for venereal 
diseases; a decoction of the seeds as a remedy for headache and tcothache. 
He states that other names for the plant were “ xochipaltic,” ‘ neuhxochitl,” 
and “ hoatzinxochitl.”

STANDLEY—TREES AND SHRUBS OF MEXICO. 1113 


Plants suffrutescent, subscandent, 1 to 3 meters high, glabrous except in the 
inflorescence; leaves short-petiolate, oblong to ovate, acuminate, acute at base; 
spikes long and slender, many-flowered ; calyx about 1 em. long; corolla 2.5 
to 3.5 em. long. “Canutillo” (Sinaloa) ; “hierba de alacran” (Sinaloa, Jalisco, 
Oaxaca, San Luis Potosi, Guanajuato); “hierba del negro” (Conzaitt) ;

tella,” “hierba del diablo” (Colombia) ; “ pegajoso” (Tamaulipas, Sinaloa) ; 
“ guacochile”’ (El Salvador). 

The leaves and root when applied to the skin produce almost instant rube- 
faction and in a very short time blisters. Taken internally they are poisonous. 
A decoction is applied externally for erysipelas, itch, and similar affections. 
Plumbago europaea L., of Europe, has similar properties. It is used inter- 
nally as an emetic. When chewed, the plant excites the flow of saliva. The 
root has long been employed to relieve toothache, hence the French name of 
“dentelaire.’ Beggars are said sometimes to employ the leaves to raise sores 
upon the body for the purpose of exciting pity. 

This species was listed by Sessé and Mocifio as P. zeylanica, an Old World 
species.

Tree, 8 to 15 meters high; leaves oval or broadly elliptic to oblong, 7 to 15 
cm. long, abruptly short-acuminate, bright green above, golden or brownish- 
sericeous beneath, the pubescence very dense and lustrous; flowers greenish; 
stigma 8 to 11-lobed; fruit the size of an apple, globose, white to purple, with 
milky sweet flesh, containing several large brown seeds. ‘“‘ Caimito” (Yucatan, 
Guerrero, Central America, Cuba, Santo Domingo) ; “ cayumito” (Yucatan). 

The wood is said to be rather coarse and purplish gray, with a specific grav- 
ity of 0.88; it is of little value. The star-apple is cultivated for its fruit, which 
is highly valued in some parts of tropical America. The fruit is eaten raw. 
‘The name star-apple is derived from the fact that when the fruit is cut trans- 
versely, the seeds are seen to raidate like the points of a star. The tree is per- 
haps not a native of Yucatan but only in cultivation there.

The fruit is said to yield a kind of “chicle.” It is eaten either fresh or 
dried, and is often seen in the markets. The imniature fruits are pickled in 
vinegar and salt, like olives. The ripe fruit is sweet and mucilaginous. 

The tree is described by Hernindez under the name “tempixquiztli.” He 
states that a decoction of the leaves was dropped into the ears and nostrils 
to allay pain, and that the leaves were heated and applied to = teeth for 
the same purpose, as well as to harden the gums.

and zicozapotl) ; “sheink” (Mixe, Belmar) ; “‘ zapote chico” (various locali-

The sapodilla or naseberry is one of the best-known tropical American 
trees. The fruit is highly esteemed by many persons. It is variable in form, 
but usually 5 to 9 em. in diameter; the flesh is yellowish brown, translucent, 
soft, sweet, and delicious when fully ripe, but when green it contains tannin 
and a milky latex. 

The most important product of the tree is “chicle” gum, which is employed 
in the manufacture of chewing gum. This is obtained by tapping the trees, 
or by pressing the fruit. That obtained by tapping is known as “chicle 
eorriente,’”’ and that from the fruit as ‘chicle blanco” or ‘“ chicle virgen.” 
The sap obtained by tapping is boiled after having been collected, and as 
a result the gum coagulates and is separated. Large mounts of the gum 
are exported from Chiapas, Tabasco, and Yucatan. The Aztecs were well 
acquainted with its extraction; the women and children chewed it, and figures 
were sometimes modeled from it.

The wood is fine, hard, and reddish. It is used for making carts and 
other articles. The bark is said to contain an alkaloid, sapotine, and is em- 
ployed locally as a remedy for fevers. Diuretic properties are attributed 
to the seeds. j 

Achras cosagiiico Llave,* described from Veracruz, is probably a synonym. 
It was described as having yellow fruit, and the vernacular name was given 
as “ cosagitiico,” which, according to Urbina, should probably be “ cozahuico.” 

The tree is described by Hernandez under the name “ xicozapotl.” For illus- 
trations see Contr. U. S. Nat. Herb. 18: pl. 46, 47.

Widely cultivated in the warmer parts of Mexico, as far north as Sinaloa; 
perhaps native in southern Mexico. Widely distributed in tropical America, 
at least in cultivation. 

Tree, 10 to 30 meters high, with milky juice, the crown rounded or de- 
pressed; bark reddish brown, shaggy; leaves deciduous, petiolate, obovate, 10 
to 380 cm. long, rounded to acute at apex, attenuate at base, pubescent beneath 
when young but soon glabrate, the lateral nerves distant, parallel; flowers 
glomerate, subsessile, on defoliate branches; sepals 8 to 10, 2.5 to 6 mm. long, 
sericeous; corolla white, 9 to 10 mm. long, 5-lobate; fruit globose or ovoid, 8 
to 20 cm. long, pointed at apex, the skin brown, scaly, the flesh pink or reddish ; 
seed 1, about 8 cm. long, smooth and lustrous except for the large ventral area.

“red haaz,” to distinguish it from the banana); “ potkak” (fruit), “kauk- 
pahk” (seed) (Mixe, Belmar); “mamey zapote” (Porto Rico); “tsapas 
sabani” (Zoque). 

The sapote (known also as “ mamee sapote” and “ marmalade-fruit’’) is 
a common fruit tree of tropical America. By many persons the fruit is highly 
esteemed, but it is rarely liked by those who have not been accustomed to it. 
The flesh is sweetish, with peculiar flavor, and is often made into marmalade or 
jelly. 

The handsome seeds, known in Mexico as “pizle” or “ pixtle,” and in 
Central America as “ sapuyul” or “ zapoyol,” are still used in Central America 
and southern Mexico, mixed with cacao and parched corn, for the preparation

STANDLEY—TREES AND SHRUBS OF MEXICO. 1121 


of a beverage, which is called “ choue”’ by some of the Mexican Indians. The 
sapote seeds are used because of their flavor, which resembles that of bitter 
almonds. In Costa Rica they were formerly employed in place of an iron 
for smoothing starched linen. In the same country, as well as in Mexico, the 
kernels are ground and made into sweetmeats. 

The wood is said to be fine-grained, hard, and compact, with a specific 
gravity of about 0.58. It is suitable for cabinet work but is little used, since 
the trees are protected for their fruit. 

There is a popular belief in Mexico that the oil of the seeds will restore 
fallen hair. According to Altamirano’* and others this results from the fact 
that the Aztecs employed it for dressing the hair, to keep it soft and to prevent 
dandruff. The seed coat was used by the Aztecs as a remedy for epilepsy, 
and in Costa Rica it is considered a cure for colds. The sap of the tree is 
said to have vomitive and anthelmintic properties and the seeds to be diuretic. 

The tree is described by Hernandez under the name ‘“ tezontzapotl.”’ He 
states that the oil of the seeds was applied to painted jicaras (cups made 
from gourds) and to other similar objects to fix their colors. The pulverized 
seed coat, drunk in wine, is said to cure the gravel and heart affections.

The fruit is edible and is found in the markets, but the tree is seldom culti- 
vated. The fruit is said to produce drowsiness, hence its name of ‘ zapote 
borracho.” The bark is reputed to have antiperiodic properties.

Tie CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 


The tree is described by Hernindez, who says: ‘The Mexicans in their 
language, which is expressive, elegant, and precise, indicate in their names 
the properties as well as the uses of plants. In this way, they apply the name 
tzapotl [zapote] as a general term to all fruits which have a sweet flavor, 
and zocotl [jocote] to those which are sour. The atzapotl or ‘water tzapotl’” 
is so called because it comes from a tree which grows near the water. It is 
a large tree, with leaves like those of the orange, and bears near the ends 
of the branches white star-shaped flowers, which produce a fruit nearly round, 
large, yellow within, and of sweet flavor. This is in a way a disagreeable 
and indigestible food, and sometimes excites fever. Within the fruit is a 
stone which is used especially for ulcers.”

2. DIOSPYROS L. Sp. Pl. 1057. 1753. 


Shrubs or trees; leaves persistent or deciduous; flowers dioecious, rarely 
polygamous, axillary, cymose or fasciculate; calyx 4 or 5-lobate; corolla urceo- 
late, campanulate, or salverform, the lobes obtuse, spreading or recurved; fruit 
baceate, containing 1 to 10 seeds. 

The genus is a large one, containing 150 or more species, most of which are 
natives of the Old World. Some of them furnish the ebony of commerce. 
Diospyros kaki L. is the Japanese persimmon, which is widely grown for its 
large handsome sweet fruit. Diospyros virginiana L. is the common persimmon 
of the eastern and southern United States. Its fruit is extremely astringent 
when green, but in fall, especially after frost, it becomes soft and sweet. It 
is a favorite wild fruit in the regions where it grows, and has been used in 
the preparation of a kind of beer, as well as distilled liquors. In the Southern 
States the seeds have been roasted and ground and used as a coffee substitute. 
The green fruit contains tannic acid, and has been employed as a domestic 
remedy for diarrhoea, chronic dysentery, and uterine hemorrhage. The bark 
is astringent and very bitter. 

The following names are reported for unplaced Mexican species of Diospyros ; 
they probably relate to D. ebenaster: “ Hinchuik,” “ huinchuik” (Mixe, Bel- 
mar); “bomuttza” (Otomi, Buelna).

Tree, 10 meters high; leaves short-petiolate, ovate-oblong or lance-oblong, 
5 to 9.5 em. long, acuminate; calyx lobes linear-lanceolate, 15 to 18 mm. long, 
long-attenuate; fruit depressed-globose, about 4 em. in diameter, green, the 
flesh black; seeds 5 to 10. ‘“ Zapote negro montés.” 

The fruit is said to be of excellent flavor, and Professor Conzatti states 
that it is superior to any of the native Mexican fruits, with the possible ex- 
ception of the chicozapote.

6. Diospyros texana Scheele, Linnaea 22: 145 1849. 

Brayodendron texanum Small, Bull. Torrey Club 28: 356. 1901. 

Coahuila, Nuevo Leon, and Tamaulipas. Western Texas. 

Shrub or tree, sometimes 16 meters high, with a trunk 60 cm. in diameter; 
bark thin, smooth, light reddish gray, the outer layers peeling off; leaves nearly 
sessile, broadly obovate or oblong-obovate, 1 to 4 cm. long, rounded or emar- 
ginate at apex; corolla sericeous, 8 to 12 mm. long; fruit black, about 2 em. in 
diameter, the pulp sweet, dark, containing 3 to 8 seeds; wood hard, compact, 
nearly black, its specific gravity about 0.85. ‘‘ Chapote” (Tamaulipas, Texas) ; 
* chapote prieto”’ (Nuevo Ledén). 

The wood is susceptible of a high polish. It has been used for turning and 
for making tool handles, and in England it is said to have been used as a sub- 
stitute for boxwood, in making engravings. The fruit is astringent when 
green but sweet when fully ripe. It leaves an indelible black stain upon every- 
thing with which it comes in contact, and is employed locally for dyeing sheep 
and goat skins. 

Diospyros cuneifolia Hiern,’ does not. appear distinguishable from the de- 
scription. It is said to come from Mexico. The writer has seen no material of 
D. texana californica T. S. Brandeg.,? which was described from Baja Cali- 
fornia. It may be a plant closely related to D. texana, but it seems more prob- 
able that it is a relative of D. sonorae, unless it should be found to be Maba 
intricata. Specimens of the last have been reported from Baja California as 
Brayodendron texanum.

Diospyros tiltzapotl Sessé & Moe. Pl. Nov. Hisp. 179. 1887. 

Cultivated in Mexico from Jalisco to Chiapas, Veracruz, and Yucatan, and 
apparently naturalized locally. Native of the Hast Indies, but widely cultivated 
in tropical America. 

Large shrub or medium-sized tree; leaves oblong or elliptic, sometimes 30 
cm. long, persistent, obtuse or acutish, glabrous; flowers polygamous; corolla 
yellowish white or greenish; fruit subglobose, shining, olive-green, the pulp 
dark and soft; seeds 4 to 10. ‘“‘ Zapote prieto” (Jalisco, Chiapas, Michoacan, 
Guerrero, Morelos, Tabasco, Yucatén, Philippines); ‘“ tauch,” “tauch ya”

Reko); ‘“tliltzapotl,’ ‘“ totocuitlatzapotl,” ‘ tlilzapotl” (Nahuatl); “ guaya- 
bota” (Porto Rico). 

This tree must have been introduced into Mexico at an early date, for it is 
mentioned by the older writers. Indeed, some writers have been inclined to 
consider it a native of Mexico, and Merrill states that it was carried from this 
eountry to the Philippines. 

The tree is said to be the source of some of the East Indian ebony. The 
fruit is eaten, but is is of poor quality. The green fruit is reported to have 
been used in the Philippines and West Indies for stupefying fish. In Mexico 
the ripe fruit is made into preserves, which are reported to be of excellent 
quality. Brandy also is said to have been made from the pulp. Urbina re- 
ports the Otomi names as “bom-rza” and “ phonimurza.” 

The tree was described by Hernandez under the name “ tlilzapotl” (“ black 
zapote”’’). He states that it was used as a remedy for leprosy, ringworm, 
and itch, and also for killing fish.

ameter; seeds 8 to 10. ‘‘ Guayaparin” (Sinaloa). 


11. Diospyros sphaerantha Standl. Contr. U. S. Nat. Herb. 18: 191. 1916. 

Type collected near Colomas, in the Sierra Madre of Sinaloa. 

Leaves deciduous, elliptic-oblong, 4.5 to 8 em. long, obtuse or rounded at apex.

S mm. long, densely sericeous. 

It is rather doubtful whether this and D. sinaloensis are distinct from D. 
reset.

The various species of ash are common in temperate regions of the Northern 
Hemisphere. Some of them furnish strong wood which is useful for building 
purposes, interior finish, furniture, and tool handles. They make excellent 
shade trees and are often planted on that account. The bark contains a glu- 
coside, fraxin, and, like the leaves, has been used in Mexico, the United 
States, and Europe as a tonic and febrifuge. A decoction of the leaves has 
been employed in Mexico particularly for yellow fever and malaria. ‘The 
leaves are said also to have purgative properties, and they have been used for 
gout and rheumatism. Frarinus ornus L., a species of the Mediterranean 
region, produces from cuts in the bark an exudate, which is an official drug. 
manna, of the United States Pharmscopoeia. It is used in medicine as a 
gentle laxative. 

There is a popular belief in some parts of the southern United States that 
ash leaves are so offensive to rattlesnakes that the latter are never found 
on land where the trees grow. Hunters are said sometimes to stuff their 
boots with ash leaves as a preventive of rattlesnake bites. 

The ordinary Spanish name for the ash tree, and the one generally em- 
ployed in Mexico, is “fresno,” a derivative of the Latin “fraxinus.” The 
following names are reported for species of doubtful identity: ‘ Yaga-guillaa,” 
“yaga-nisse” (Oaxaca, Zapotec, Reko); “paramu” (Michoacin, Tarascan,

4. Fraxinus schiedeana Schlecht. & Cham. Linnaea 6: 391. 1831. 

Veracruz; type from Jalapa. 

Large shrub or small tree; leaflets 5 to 9, oblong, lance-oblong, or elliptic, 
sessile, narrowed to the obtuse apex, attenuate at base, glabrous, subcoriaceous, 
lustrous, the margins subrevolute; samaras about 1.5 em. long, the wing longer

Frazinus jonesii Lingelsh. in Engl. Pflanzenreich IV. 2431: 35. 1920. 

Type from Valley of Palms, Baja California; reported from Chihuahua. 

A tree; rachis very narrowly winged; leaflets usually 5, oval, sessile or nearly 
so, 0.5 to 2 em. long (very immature), 0.5 to 1 em wide, entire or obscurely 
crenulate, whitish-pilose on both surfaces, especially beneath.

Frazvinus dipetala trifoliolata Torr. U. S. & Mex. Bound. Bot. 167. 1859. 
Baja California. California. 

Shrub or small tree; leaves simple, or the leaflets 3 to 9, cue nents 
oblong to oval or rounded, obtuse or acute, entire or nearly so, thin, glabrous; 
flowers white, with 2 large petals, the panicles about as long as the leaves; 
samaras 2 to 8 cm. long. 

In the typical form there are 5 to 9 leaflets. The Mexican material is 
F. dipetala trifoliolata, characterized by having simple or trifoliolate leaves. 
It was reported from Baja California by Goldman’ as F. attenuata Jones. 


7%. Fraxinus potosina T. S. Brandeg. Univ. Calif. Publ. Bot. 4: 275. 1912. 
Type from Minas de San Rafael, San Luis Potosi. 
Plants glabrous; leaves simple, suborbicular, 1 to 2.5 em. long, entire or 
serrate, coriaceous; Samaras 4 to 5 mm. long, the wing rounded at apex, much 
shorter than the compressed body. 


8. Fraxinus nummularis Jones, Contr. West. Bot. 12: 59. 1908. 

Coahuila; type from Sierra Mojada. 

Shrub with stiff branchlets; leaves mostly simple but sometimes trifoliolate, 
the simple leaves oblanceolate to oval, 1 to 2.5 cm. long, obtuse, glabrous, 
subcoriaceous; flowers apetalous; wing of the samara much longer than the 
body. 

It seems probable that this is a form of F. greggii, bearing the same relation 
to the latter that F. dipetala trifoliolata does to F. dipetala. In the type 
collection of F. nummularis all the leaves are simple and oval. A specimen 
from Sierra de Parras (Purpus 5064) shows leaves of the same kind, but some 
of the leaves are trifoliolate, and some of the simple ones are exactly like the 
leaflets of F. greggii.

10. Fraxinus berlandieriana A. DC. in DC. Prodr. 8: 278. 1844. 

Coahuila to Veracruz and Durango. Western Texas, the type from Austin. 

Tree, 10 to 12 meters high, the trunk about 30 cm. in diameter; bark thick, 
gray, fissured; leaflets 3 to 7, lanceolate or oblong, petiolulate, 4 to 18 em. 
long, acute or attenuate, thick, remotely serrulate or subentire; flowers 
dioecious; Samaras 2.5 to 3.5 em. long, the body terete. ‘“ Plumero” (Vera- 
cruz); “fresno” (Nuevo Leén, Durango). 

This species is often planted as a shade tree in northeastern Mexico. The 
samaras are sometimes 3-winged.

to southern California; type from New Mexico. 

Small tree, usually 12 meters high or less, the trunk 20 cm. in diameter; 
bark gray and rough; leaflets 5 to 9, oblong, lanceolate, or ovate-oblong, 4 to 
7 cm. long, acute or acuminate, serrate or subentire; samaras 2 to 3 em. long,

Frazinus americana uhdei Wenzig, Bot. Jahrb. Engler 4: 182. 1883. 
Sinaloa to San Luis Potosi, Veracruz (?), and Oaxaca. 

Tree, 15 to 18 meters high, with dark furrowed bark; leaflets 5 to 9, usually 
long-petiolulate, lanceolate or oblong-lanceolate 7 to 15 cm. long, long-attenuate, 
obtuse or acute at base, Serrulate, barbate beneath along the costa but else- 
where glabrous; flowers in large panicles, these sometimes 20 cm. long; samaras 
2.5 to 4 em. long. “Fresno” (Jalisco, Sinaloa). 

Often planted as a shade tree in the Valley of Mexico, at Guadalajara, and 
elsewhere. x 

It is not certain that the specimens described and referred here are identical 
with those to which Wenzig applied the name whdei. They agree well with 
his diagnosis except for his statement that the leaflets are sessile. 


13. Fraxinus papillosa Lingelsheim, Bot. Jahrb. Engler 40: 219. 1907. 
Mountains of Chihuahua; type from Colonia Garcia. Southern New Mexico. 
Tree; leaflets 5 to 9, sessile, elliptic to ovate-oblong, 3 to 6 em. long, acute, 

serrulate or subentire, glabrous; samaras 2.5 to 3 cm. long, the wing obtuse or 

emarginate. 


14. Fraxinus standleyi Rehder, Proc. Amer. Acad. 53: 208. 1917. 

Mountains of northern Sonora. Southern New Mexico and Arizona; type 
from Organ Mountains, New Mexico. 

Tree, usually small but sometimes 15 meters high; leaflets 5 to 9, sessile or 
petiolulate, elliptic to lanceolate, 4 to 11 cm. long, acute or attenuate, serrulate, 
glabrous or pubescent beneath; samaras 2 to 3 em. long. 

It is doubtful whether this is distinct from F. papillosa and F. pringlei, and 
the three will probably have to be united ultimately. 


15. Fraxinus pringlei Lingelsheim, Bot. Jahrb. Engler 40: 221. 1907.

Known in the United States as “ devilwood.” The writer has seen two 
Mexican specimens, one from Cumbre del Obispo (Schiede), and one from Monte 
Pelado, Oaxaca (Galeotti 529). Although not in the best condition for com- 
parison, they seem to agree perfectly with specimens from the United States.

1142 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. — 


A handsome vine, known in the United States as “ yellow jasmine.” The 
root is reported to contain an alkaloid, gelsemine. A tincture of the root is 
sometimes administered in domestic practice for rheumatism and gonor- 
rhea. It is said to act as an arterial sedative, and in larger doses to produce 
insensibility to pain, but its use is dangerous or even fatal. Large doses are 
said to cause vertigo and perverted vision.

1. Plocosperma microphyllum Baill.; Solenreder in Engl. & Prantl, Pflan- 
zenfam. 42: 50. 1895. 

Oaxaca, and perhaps elsewhere. 

Rigid shrub; leaves fasciculate or opposite, subsessile, oval or oblong, 8 to 
13 mm. long, rounded or shallowly emarginate at apex, rounded at base, entire, 
coriaceous, glabrous; flowers solitary or fasciculate in the axils, 5-parted; 
fruit a terete capsule, 4 to 6 cm. long, 3 to 4 mm. in diameter; seeds 2, about 2 
cm. long, each with a dense tuft of silky bristles at the apex. 


3. STRYCHNOS L. Sp. Pl. 189. 1753. 


The genus consists of about 200 species of trees, shrubs, or vines, dis- 
tributed in the tropics of both hemispheres. Some of the species have edible 
fruit. The seeds of S. nuz-vomica L., of India, furnish the drugs strychnine 
and nux-vomica. 


1. Strychnos tepicensis Standl., sp. noy. 

Sinaloa and Tepic; type from Acaponeta, Tepic (Rose 1441; U. S. Nat. Herb. 
300272). 

Branches glabrous or when young sparsely hirtellous; leaves opposite, the 
petioles 3 to 5 mm. long, hirtellous or glabrous, the blades ovate-elliptic, 5.5. 
to 10 em. long, 2.5 to 5 em. wide, acuminate or long-acuminate, obtuse at 
base, coriaceous, glabrous, entire, quintuplinerved, the venation prominent be- 
neath; seeds strongly compressed, rounded-triangular or rounded, about 2 cm. 
in diameter and 6 mm. thick. 

The material is very imperfect, consisting of leafy branches and a few seeds, 
but it seems desirable to assign a specific name to it for the purpose of con- 
venience. 

No species of the genus has been reported definitely from Mexico, but there 
are casual reports of S. triplinervia Mart., a Brazilian plant, from San Juan 
Bautista, Tabasco, where it is said to be known as “cabalonga de Tabasco,” 
“ mata-perros,” and “ veneno del diablo.” The Tabascan plant is probably not 
8. triplinervia, but it may be one of the few species that have been described 
from Central America.

nal thyrsiform panicles, sweet-scented; calyx tubular, 4-lobate; corolla tubular, 
8.5 em. long, greenish yellow; stamens 4, exserted; fruit a 2-celled capsule. 

The genus was named for Major William H. Emory, United States Com- 
missioner to the Mexican Boundary Survey.

5. BUDDLETA L. Sp. Pl. 112. 1753. 


Shrubs or small trees, usually with stellate tomentum; leaves entire or 
toothed; flowers small, in heads or dense cymes, these solitary and axillary or 
spicate or paniculate; calyx campanulate, 4-dentate; corolla short-salverform, 
the 4 lobes imbricate, spreading in anthesis; stamens 4; capsule septicidally 
bivalvate. } 

Some of the Old World species have showy flowers and are cultivated for 
‘ornament. The leaves of B. madagascariensis Lam. were formerly employed 
in Madagascar as a soap substitute, and the plant is used as a remedy for 
asthma, coughs, and bronchitis. Some of the members of the genus are said 
to be used for poisoning fish. The usual Mexican name for all the species 
is “ tepozdn.” 

Under the name ‘“topogan,”’ Sahagtin mentions one species which was 
employed as a diuretic and to “regulate the digestion and moderate the 
heat of the body.” In another place he says: ‘There is a medicinal tree 
called tepogan. Its leaves are long, velvety, rounded, and pointed. In color 
they are somewhat whitish green, and they exhale a rather unpleasant odor. 
The tree is good for heat of the head in either children or adults. The roots 
are large and long and have a Slightly disagreeable odor. Cut up, pulverized, 
and mixed with the root of tepexilozochitlacotl, they are good to stop nose- 
bleed.” 

Hemsley listed 26 species of Buddleia from Mexico, and others have been 
described since. Many of them, however, have been based upon trivial char- 
acters and must be reduced to synonymy.

A related species, P. tricolor Ruiz & Pav., in which the corolla is pink and 
yellow within, red and white outside, is said to be cultivated in Mexico, 
and to be known as “flor de mayo” and ‘‘ensalada.” The corollas are said 
to be used for making sweetmeats and as a remedy for coughs.

The beautiful sweet-scented flowers were a favorite among the ancient 
Mexicans, and especially popular with the nobility. They are still greatly 
admired by the Mexican people, who often plant the tree in their gardens and 
use the flowers for decorations, especially in churches. The Indians often 
wear them in their hair. The name ‘“frangipanni” is applied to this and 
related species, likewise ‘temple flower” and “graveyard-flower.” The juice 
is sometimes employed in treating wounds and venereal diseases, and it is 
said to produce a good quality of rubber.

The tree is showy when in flower and is often cultivated in the tropics. In 
Florida it is known as “ trumpet-flower” and “ yellow oleander,” and in the 
British West Indies as “lucky-nut,” and ‘“ luck-seed.” The flowers are very 
sweet-scented. The wood is said to be soft and fibrous and to have a specific 
gravity of about 0.80. The milky juice and the seeds are poisonous. In Yuca- 
tin cotton soaked in the juice is placed in cavities in teeth to relieve tooth- 
ache. The seeds have been reported to yield a glucoside, thevetine. A tinc- 
ture of the bark is considered a powerful febrifuge and in large doses is a 
violent purgative and emetic.

and Tehuilotepec (Guerrero). 

Shrub or small tree, 3 to 9 meters high; leaves 7 to 14 cm. long, 5 to 10 
mm. wide, acute or attenuate, long-attenuate at base, the margins usually 
revolute; corolla 8 to 9 em. long, the tube shorter than the limb; fruit about

The seeds contain about 40 per cent of oil and also a glucoside, thevetin, 
and they are considered very poisonous. Taken internally they act as a 
violent vomitive, hinder respiration, and cause paralysis of the heart. 
They have been given in Mexico as a substitute for digitalis, but their use is 
dangerous. They are a popular remedy for hemorrhoids, and some of the 
Indians consider them a remedy for rattlesnake bites. They are said to have 
been worn about the ankles as rattles in certain dances. The leaves or the 
juice were employed by the Aztecs for deafness, cutaleous diseases, ulcers, 
and toothache.

The plant has milky sap. The crushed root was employed in Guerrero, ac- 
cording to Sessé and Mocifio* (who list the plant as Rawwolfia nitida, a West 
Indian species), as a remedy for erysipelas, and the leaves for healing ulcers. 
In Colima the root decoction is used as a gargle for the throat and as a wash 
for the gums. The juice of the fruit is used as ink and also for dyeing. The 
fruit itself is reputed to be poisonous. ;

Lochnera rosea Reichenb. Consp. Veg. 134. 1828. 

Ammocallis rosea Small, Fl. Southeast U. S. 936. 1903. 

Cultivated in Mexico for ornament and in some places naturalized ; specimens 
have been seen only from Sinaloa and Yueatén, but the plant must be much 
more widely distributed. Widely dispersed in the tropics of both hemispheres. 

Plants herbaceous or woody at base, 1 meter high, thinly pubescent; leaves 
opposite, short-petiolate, oblong to elliptic, 3 to 8 em. long, obtuse or retuse; 
flowers solitary or geminate in the axils; calyx 5-cleft; corolla salverform,

“Jazmin del mar” (Porto Rico) ; ‘ vicaria,”’ ‘‘ Dominica” (Cuba) ; “chichirica ” 
(Philippines) ; “ chula,” ‘‘mulata” (El Salvador). 

In the United States and the British West Indies the plant is known as 
“vinea,’ “old maid,” “red periwinkle.” and erroneously as ‘“ sweet-william.” 
The flowers are showy and the plant is easily propagated. In Madagascar 
the bitter astringent leaves are employed as a vomitive, and the roots are 
said to be purgative, vermifuge, depurative, and hemostatic, and to be a 
remedy for toothache.

1. Nerium oleander L. Sp. Pl. 209. 1753. 

Cultivated in all the warmer parts of Mexico, and in places naturalized. 
Native of the Mediterranean region, but cultivated in all warm regions and 
in many places naturalized. 

Shrub or small tree, glabrous or obscurely puberulent; leaves mostly ternate, 
short-petiolate, linear-oblong or linear-oblanceolate, acute, coriaceous; flowers 
pink or white, fragrant, often double, in terminal cymes; calyx 5-parted, 
glandular within; corolla funnelform, the limb 5-lobate; follicles elongate, 
straight, appressed. ‘“ Laurel rosa,” “laurel blanco,” “laurel colorado” (Mex- 
ico, Porto Rico, Ecuador) ; ‘ adelfa” (Mexico, Porto Rico, Ecuador, Guam) ; 
“ yaga-quiegueze”’ (Oaxaca, Zapotec, Reko); “narciso” (Guatemala, El Sal- 
vyador) ; “‘berberia”’ (Venezuela); ‘‘rosa laurel” (Mexico, Guam); “ adelfa 
sencilla’ (Porto Rico); “laurel rosado” (Porto Rico, Colombia); “flor de 
Habana ” (Colombia). 

The oleander is one of the handsomest of cultivated shrubs and is abun- 
dantly planted in Mexican parks and gardens. The plant contains alkaloids 
which act as a powerful cardiac poison, and has been employed in medicine 
as a heart stimulant and tonic. It has long been used in southern Europe for 
destroying rats, and sometimes for poisoning people. An infusion of the

leaves in oil has been used as a remedy for cutaneous diseases and to de- 
stroy parasites. In Venezuela the juice of the leaves has been employed for 
keeping away or destroying flies, and also to remove warts.

(Oaxaca); “atempatli” (“ flea-medicine”) or “actimpatli’” (Nahuatl). 

The plant is well known in Mexico as an insecticide. A decoction of the 
plant is mixed with cornmeal and used as a poison for cockroaches. The de- 
eoction is also applied as a lotion to the human body to kill all sorts of para- 
sites and a lard ointment is employed for the same purpose. Flores states 
that a sweetened infusion of the plant will attract and kill mosquitoes.

The milky juice yields rubber, and the plant has been cultivated in some 
regions on that account. The rubber is said to be of good quality, but it is 
produced only in small amounts. The stems are said to yield a good quality 
of fiber. Cryptostegia madagascariensis Bojer, of Madagascar, the only other 
species, is reported to be an important source of rubber, and its bark furnishes 
a useful fiber.

22. VINCETOXICUM Walt. Fl. Carol. 104. 1788. 


Plants usually scandent, fruticose or herbaceous; leaves mostly cordate; 
flowers small or large, green, brown, or nearly black; calyx 5-parted, glandu- 
lar within; corolla rotate, shallowly or deeply lobate, often reticulate-veined; 
corona annular, adnate to the corolla, entire, dentate, or lobate; stigma de- 
pressed; follicles smooth or muricate; seeds usually with an apical tuft of 
hairs. 

Besides the species listed below, several herbaceous ones, with erect or subs- 
candent stems, occur in Mexico. Of a number of the species listed, no speci- 
mens have been seen, and it may be, consequently, that some names are incor- 
rectly placed in the key. 

The following vernacular names are reported for plants of this genus: 
“ Chimicuro” (Oaxaca); ‘ gueto de venado” (Oaxaca); ‘“tlalayote” (Oax- 
aca). The name most commonly used is “talayote.” The young fruits are 
eaten either raw or coked. Sweetmeats are sometimes made by boiling them 
in sirup.

large, very showy flowers open late in the evening. The milky juice is em- 
ployed in tropical America for coagulating the latex of Castilla, the rubber 
tree. In India the young seeds are eaten, and the plant is there a popular 
remedy for snake bites. In El Salvador the stems are employed for hanging 
tobacco to dry.

When in flower the plant is very showy, rivaling Bougainvillea, which it 
strongly suggests. The leaves are usually but not always absent at the time 
of flowering. The roots are large, watery, and sweet, and they are often 
eaten along the Pacific coast, either raw or cooked. The plant is illustrated 
by Hernandez.”

seeds black. ‘Palo blanco” (Sonora, Sinaloa); ‘‘ palo del muerto,” “ casa- 
huate,” ‘“ quauhzahuatl,” “ casahuate blanco” (Morelos); “palo santo” (So- 
nora); “palo bobo” (Morelos, El Salvador) ; “tutumushte,” ‘“ siete pellejos,” 
“Siete camisas”’ (Il Salvador). 

When in flower the tree is a very showy one. It blooms when leafless. In 
Some localities it forms extensive forests known as “ casahuateras.” In Mo- 
relos there is a popular belief that the tree causes imbecility and other cerebral 
affections, and for this it is necessary only to drink the water running at the 
foot of the trees. It is reputed also to be poisonous to horses and eattle. In 
Sinaloa the bark is used as a remedy for bites of rattlesnakes and other 
poisonous animals, and for diseases of the spleen.

The shrub is a handsome one when in full flower. A form with yellow 
flowers, growing about the City of Mexico, is L. mexicana lutea Brand.” A 
specimen from Tlaxcala is said to have nearly white flowers. 

A decoction of the leaves is much used in Mexico as a remedy for fevers, 
and is said to have emetic, purgative, diuretic, and sudorifie properties. It 
is employed also as a wash to prevent falling of the hair. The plant is said 
to contain an alkaloid, loeseline. The early inhabitants used the plant like 
soap, crushing it in water until a suds was formed.’

Loeselia involucrata is maintained by Brand as distinct from LD. ciliata, the 
two with L. amplectens forming a “species collectiva.” He states that in 
L. ciliata the outer bracts are cordate but not clasping, while in DL. involucrata 
they are deeply cordate-clasping. There does not appear to be any essential 
difference between the two forms.

The species are known in California as “hierba santa.” The dried leaves 
are official in the U. 8S. Pharmacopoeia, and are used in the treatment of 
asthma, chronic bronchitis, and inflammation of the genito-urinary tract. 
They contain two aromatic resins and tannic acid. The plants have long 
been employed in California as a bitter tonic and a stimulant balsamic ex- 
pectorant, and sometimes as a remedy for rheumatism. The Coahuilla Indians 
of southern California applied the leaves as poultices to sores upon men 
and beasts, and bathed sore parts or fatigued limbs with a decoction of the 
plant.

The wood is said to be hard and strong, yellow, with a specific gravity of 
about 0.78, and to be used in carpentry. The leaves and flowers are reported 
tc have emollient properties and to be used for treating affections of the chest. 
A decoction of the flowers is sometimes employed for inducing perspiration. 
In El Salvador a French physician formerly prepared from.the charcoal a 
preparation which was much used for treating affections of the stomach. 
The fruit is employed in Oaxaca for coagulating indigo. It is white, trans- 
parent, mucilaginous, and extremely sweet, and is often eaten. The viscid 
juice is used in El Salvador for fastening the wrappers of cigars.

The wood is highly valued for carpenter and cabinet work, and is used 
for beams, flooring, ceiling, and finer work. The smaller branches are some- 
times employed for making barrel hoops. The forks of the young twigs are 
almost always enlarged by hollow swellings, which afford shelter for fierce 
ants, hence the name ‘“ hormiguero.” The fruit is edible. A decoction of the 
leaves is employed as a tonic and stimulant, especially in the ease of catarrh 
and affections of the lungs, and an ointment made with the pulverized seeds 
has been used in the West Indies as a remedy for cutaneous diseases. The 
fresh bark is reported to have an odor suggestive of garlic.

obtuse, rounded or cordate at base, scabrous above, entire or nearly so; 
flowers in small dense cymes; calyx 1 em. long, the teeth acute; corolla 3 
to 4 cm. long, white, with yellow throat, the lobes crispate; fruit ovoid, 2.5 
to 8 em. long, reddish brown, shining, the flesh sweet; wood soft, close- 
grained, brown, its specific gravity about 0.68. “ Anacahuite,” ‘ anacahuitl,” 
“anacahuita” (Tamaulipas, Guanajuato, Nuevo Leon, Texas; from the 
Nahuatl amacuahuitl, “‘ paper-tree”’) ; ‘ siricote” (Tamaulipas) ; “ nacagiiita ” 
(Nuevo Leén) ; “trompillo” (Tamaulipas, Nuevo Leén); ‘“ nacahuite” (San 
Luis Potosi); ‘‘nacahuitl” (Nuevo Leén). 

The tree is often planted for ornament and is very handsome when covered 
with flowers. The fruit is eaten by people but if eaten raw it said to cause 
dizziness, as if one were intoxicated. Domestic animals are fond of the 
fruit and hogs eat the seeds. The wood is of little value, but yokes and 
other articles are made from it. All parts of the plant are aromatic. Jelly 
made from the fruit is much used as a remedy for coughs and colds. A 
decoction of the leaves is a popular domestic remedy for rheumatism and 
is generally employed in the treatment of bronchial affections. About 1860 
the wood attracted some attention in Germany as a possible remedy for 
tuberculosis and quantities of it were exported from Tampico. Analys’s, 
however, showed that it did not possess important medicinal properties, 
and experience proved that no good results followed its use, consequently it 
was not long employed.

probable that the plant is the same as B. formosa, and if so the name B. huanita 
should replace that one. Bourreria huanita is mentioned in various Mexican 
publications and the following vernacular names are reported: ‘ Huanita” 
(Michoaein); ‘izquixochitl,” “esquisfichil”; ‘‘jazmin de Tehuantepec” 
(Oaxaca) ; “ yaga guiexoba”’ (Oaxaca, Zapotec).

1. Ehretia tinifolia L. Syst. Nat. ed. 10. 936. 1759. 

Tamaulipas, Veracruz, Oaxaca, and Yucatéin. West Indies. 

Shrub or tree, glabrous throughout or nearly so, sometimes 27 meters high, 
with dense crown, the bark rather smooth; leaves petiolate, oblong to ovate, 
5 to 12 cm. long, rounded to acutish at apex, obtuse or rounded at base, 
lustrous; panicles longer than the leaves, dense or open; corolla white, about 
4 mm. long; fruit 5 to 6 mm. in diameter, red or purple. ‘“ Nandimbo” 
(Oaxaca) ; ‘“‘manzana” (Tamaulipas, Veracruz) ; “ manzanita’ (Tamaulipas) ; 
“roble,” “ beec,” “hee,” “safico” (Yucatén) ; “capulin cimarrén” (Oaxaca) ; 
“roble prieto”” (Cuba). 

The fruit is edible. The tree is often planted for shade. 

The description of H#. longifolia Miers,’ which was based partly upon speci- 
mens from Jamaica and partly upon a specimen collected between Tehuacin 
and Oaxaca, suggests this species, and Miers’s name is probably to be reduced 
to synonymy. 


2. Ehretia elliptica DC. Prodr. 9: 503. 1845. 

Ehretia ciliata Miers, Ann. Mag. Nat. Hist. IV. 3: 111. 1869.

‘into thin, gray or reddish scales; leaves oblong to rounded, 3 to 7 cm. long, 
usually rounded or obtuse at base and apex, thick, very scabrous or some- 
times glabrate beneath; panicles small, dense or open; flowers sweet-scented ; 
corolla 6 to 7 mm. long; fruit 5 to 8 mm. in diameter, yellow; wood hard, 


weak, brown, close-grained, it specific gravity about 0.64. ‘“ Manzanita,” 
“manzanillo” (Tamaulipas) ; “‘anacua” (Nuevo Leén, Tamaulipas, Texas) ; 
“anagua”’ (Nuevo Le6én) ; “ anacahuite” (Guanajuato). 

In Texas the tree is known as “sugarberry,” “nockaway,” and ‘“ knack- 


away,” the last two names being corruptions of the Mexican “ anacua,” which 
is itself an abbreviation of “‘ anacahuite.” The tree is often planted because 
of its dense foliage and handsome flowers. The wood is used for wheel spokes, 
axles, tool handles, and yokes. The fruit is sweet and edible.

A closely related species is LZ. triphylla (L’Hér.) Kuntze (L. citriodora 
H. B. K.), the lemon verbena, a native of South America but often cultivated 
in Mexican gardens. It is easily recognized by its much larger ternate 
leaves. In Mexico it is said to be known as “cedr6én,” ‘“ hierba Luisa,” and 
“hierba de la princesa.” The name “cedrén” is used also in South America, 
and in Peru the plant is known as “cedroncillo.” In Mexico the plant is 
employed in domestic medicine as an antispasmodic and emmenagogue, and in 
other regions it is employed for various purposes. In southern Europe per- 
fume has been manufactured from the leaves.

leaves rounded-ovate to oblong-ovate, 4 to 12 cm. long, acute or short-acumi- 
nate, sometimes obtuse, acute to subcordate at base, crenate, scabrous above,

The lantana is a rather showy shrub when in flower and it is often planted 
for ornament and grown in hothouses. The plants bloom nearly all the year. 
This species has been introduced into most tropical countries, and in some 
of them, as in Hawaii, it has become a troublesome weed. The fruit is sweet 
and edible but not very palatable. A decoction of the leaves is sometimes 
employed as a remedy for rheumatism and as a tonic for the stomach. In 
Sinaloa the plant is a favorite remedy for snake bites, a strong decoction of 
the leaves being taken internally and a poultice of crushed leaves applied to 
the wound. .

The flowers are fragrant and the whole plant, as in other species, has a 
strong aromatic odor. Palmer reports that in Tamaulipas pieces of the leaves 
or stems are put in the ears as a cure for deafness. 

The only Mexican specimens which are exactly like the West Indian ones 
are those from Yucatéin. In the West Indian plant the leaves are usually 
rounded at the apex and finely crenate, while in the common Mexican form 
(L. velutina) the leaves are more commonly acute or acutish, more coarsely 
crenate, and more copiously pubescent. There are, however, some interme- 
diate forms, and it does not seem advisable to consider L. velutina a distinct 
species.

The white sage is a very common shrub in southern California and it is 
an important honey plant. The Indians of the region gather large quantities 
of the seeds, parch them, and grind them into meal in a mortar. The meal 
is stirred into water and salted, thus forming pinole, which is eaten or drunk.

verticillate and racemose; calyx 2-lipped, the upper lip entire or 3-dentate, 
the lower bidentate; corolla conspicuously bilabiate; fertile stamens 2. 

Many herbaceous species occur in Mexico, at least 100 or more. The best- 
known plant of the genus is Salvia officinalis L., the garden sage, a native 
of the Old World, whose aromatic leaves are used for flavoring food. Some of 
the herbaceous species are known in Mexico as “ chia,’ and a favorite bever- 
age, known by the same name, is prepared by soaking the mucilaginous seeds 
in water.

This species has been reported from Mexico as Solandra grandiflora Swartz, 
a West Indian plant. Solandra macrantha Dunal, described from Cuba, is 
probably a synonym of S. nitida.

This plant is common in cultivation in the warmer parts of Mexico, being 
extremely showy when in flower. It has usually been known as D. arborea. 
Some of the cultivated forms have double flowers. It is, probably, this species 
of which Acosta wrote in 1606, as follows: “It is true that many of these 
flowers [of New Spain] are only good to look at, for their odor is not good, 
or is ordinary, or else they have none at all, but there are some of excellent 
odor. Such are those that grow on a tree called floripondio, which has no fruit, 
but bears only flowers, which are larger than fleur de lys, shaped like hand- 
bells, all white, and having within filaments such as one sees in a lily. It 
bears flowers all the year long, whose odor is wondrously sweet and pleasant, 
especially in the fresh morning air. The Viceroy Don Francisco de Tollede 
sent some of these trees to King Philip, as a thing worthy of being planted 
in the royal gardens.” 


2. Datura arborea L. Sp. Pl. 179. 1753. 

The only Mexican specimens seen are from Sinaloa, where the plant is prob- 
ably cultivated. Native of South America, the type from Peru. 

Shrub or small tree; leaves broadly ovate or elliptic, acuminate, entire or re- 
pand, villosulous; corolla white, 15 to 18 em. long, the lobes long-cuspidate ; 
fruit subglobose, about 6 cm. long, “ Floripondio ” (Colombia, Peru, Ecuador) ; 
’“borrachero,” ‘ guante’” (Colombia) ; ‘ floripundio” (Sinaloa). 

In Peru the leaves are applied as poultices to sores to relieve pain and ac- 
celerate suppuration. 

Datura sanguinea Ruiz & Pav., a South American species with red flowers, is 
cultivated about the City of Mexico.

entire, finely villosulous or glabrate; corolla white, 25 to 30 cm. long, the 
lobes cuspidate. ‘“ Campanilla,” “flor de campana,’ ‘floripundio blanco,” 
“aérbol de la bibijagua ” (Cuba). 


6. LYCIUM L. Sp. Pl. 191. 1753. 


Shrubs, sometimes scandent, usually spiny; leaves entire, small; flowers 
solitary or fasciculate in the axils or in terminal cymes, white or purplish; 
calyx campanulate or tubular-campanulate, 3 to 5-lobate; corolla funnelform 
or salvyerform, with short or elongate tube, the limb 4 or 5-lobate; stamens 
included or exserted; fruit a globose or ovoid, 2-celled berry. 

The fruit of the Mexican species is edible but insipid. The Indians formerly 
made considerable use of it, sometimes drying and preserving it until winter. 
The leaves of L. barbarum L., of the Mediterranean region, have been em- 
ployed as a substitute for Chinese tea. The young shoots of L. europaeum 
L. are said to be eaten as a vegetable in Spain and Italy.

and Central American Solanums of the subsection Torvaria, Proc. Amer. Acad.

Shrubs or herbs, sometimes scandent, the pubescence often of branched hairs; 
leaves entire, lobed, or pinnate; flowers usually cymose, racemose, or umbel- 
late; calyx campanulate, 5-dentate or 5-lobate; corolla rotate, 5-angulate or 5- 
parted; filaments short, the anthers sometimes unequal, connate or connivent; 
fruit a globose berry. 

Many herbaceous species occur in Mexico. Hemsley lists 139 species of 
Solanum from Mexico and Central America, but it is doubtful whether so 
many occur in the region. A rather large number of shrubby species are 
known to the writer only from Dunal’s descriptions, and only a few of them 
have been placed in the following list. Many of them are based upon Pavén 
specimens which may have come from South America rather than Mexico. 

The genus contains several species of economic importance, among which 
may be noted the potato, Solanum tuberosum L., native of the South American 
Andes, and the eggplant (“berenjena”), Solanum melongena L., a native of 
. Asia and Africa.

Black nightshade is a common weed in Mexico as well as in the United 
States. The berries are commonly believed to be poisonous and there is little 
doubt that they are in some instances, but some forms of the plant have been 
introduced into cultivation under the names “ wonderberry” and ‘“ garden 
huckleberry,” and their fruit is quite harmless and highly valued by many 
persons, especially for making pies. In Mexico and Central America the young 
shoots and leaves are commonly cooked as a pot herb, and the same practice is 
followed in Mauritius, Madagascar, and other countries. In Sinaloa the root 
is said to have been employed as a remedy for bubonic plague. Hlsewhere in 
Mexico the fruit is a domestic remedy for erysipelas, and a decoction of the 
plant is employed as a fomentation for sore eyes and for various skin diseases. 
The leaves are sometimes applied as poultices to allay pain. In Europe the 
plant is generally reputed to have narcotic properties, and in Bohemia the 
leaves are placed in the cradles of infants to promote sleep. 

Solanum nigrum is a somewhat variable plant, and many of the forms (in- 
cluding several from Mexico) have been described as distinct species.

The plant is employed locally as a remedy for fever and ague. It is probably 
this species which was mentioned by Berlandier* as occurring in Texas where 
it was known as “cenicilla.” Berlandier states that an infusion of the leaves 
was used by the Indians as a febrifuge. He proposed a new genus for the 
plant and called it Teranea frutescens, in honor of General Mier y Teran, the 
director of the expedition, but no formal description of the genus was published.

3 or 2-foliolate, the terminal leaflet often replaced by a trifid tendril; leaflets 
ovate or rounded-ovate, 6 to 10 cm. long, usually short-acuminate, truncate or 
cordate at base, entire, finely lepidote and often pubescent; flowers white, turn- 
ing yellow in age, in terminal racemes or panicles; calyx campanulate, sub- 
truncate; corolla campanulate-funnelform, 4.5 to 5 em. long, curved, tomentulose 
outside; fruit oblong or elliptic, 15 to 20 em. long, 4.5 to 6.5 em. wide, somewhat 
compressed, the valves hard and woody, densely covered with large sharp tuber- 
cles; seeds broadly winged, 6 to 8 cm. broad. ‘‘Giiico”’ (Sinaloa); ‘‘xnetoloc”’

The large seeds are light and float through the air, hence the names “ mari- 
posas”’ (‘‘butterflies’) and “palomitas” (“‘little doves’’) applied to them. 
They are widely used in Mexico as a remedy for headache, being moistened and 
stuck upon the forehead. The hard portion of the seed is ground, mixed with 
tallow, and applied to the temples as a remedy for sore eyes (in Tamaulipas, 
according to Palmer). A decoction of the flowers is said to have been used by 
the Aztecs as a remedy for fevers. The curious rough fruits are used as back 
seratchers and pin-cushions.

The shrub is sometimes known as ‘‘trumpet-flower”’ or ‘‘yellow elder.” It is 
a showy plant and is common in cultivation. The flowers are slightly fragrant 
and are said to yield much honey. The wood is of little value but it was formerly 
used by the Indians for making bows. The roots are reported to be a powerful 
diuretic, and tonic, antisyphilitic, and vermifuge properties are ascribed to the 
plant. In Veracruz a decoction of the flowers and bark is administered for pains 
in the stomach, and in some parts of Mexico the plant has the reputation of 
alleviating and even curing diabetes. At Guadalajara the roots are said to be 
used for making a kind of beer. 

The species is a variable one, but although the writer has spent a large amount 
of time in study of the extensive series of specimens available, it has been impos- 
sible to find any reliable characters by which to assign the material to two or more 
species. In the typical form the leaflets are usually glabrous. T. stans velutina 
is a form in which the leafiets are pubescent or tomentose beneath. This has 
usually been maintained as a distinct species, but there is every possible gradua- 
tion between the forms with glabrous leaflets and those with tomentose ones. 
Tecoma stans angustata Rehder ! (Stenolobium incisum Rose & Standl.) is a form 
common in northeastern Mexico and the adjacent United States in which the 
leaflets are unusually narrow and incised-serrate.

STANDLEY—TREES AND SHRUBS OF MEXICO £32k 

This is an important timber tree in some parts of Mexico and Central America, 
and furnishes wood of excellent quality for house building, cabinet work, wagons, 
oars, and other purposes. In Europe the wood has been employed as a substitute 
for boxwood in engraving. In Cuba the plant is considered an antidote for 
poisoning by manchineel (Hippomane mancinella), and it has been used in some 
regions (the decoction, taken internally) as a remedy for snake bites. The 
powdered bark and leaves were formerly used in the Antilles as a febrifuge. 

When in flower, Tabebuia pentaphylla is one of the most showy and most beau- 
tiful of American trees and an extensive stand of them is a sight long to be remem- 
bered. The blossoms exhibit great variation in color, ranging from nearly white 
to deep purple-pink. The color effect produced is strikingly like that seen in 
Japanese cherries. 

Specimens from Central America identified as Couralia rosea (Bertol.) Donn. 
Smith do not appear to differ from Tabebuia pentaphylla.

Colima. Guatemala and El Salvador; type from Cuyuta, Guatemala. 

Tree, 15 to 25 meters high, the trunk often 1.2 meters in diameter; leaflets 
5 or 7, long-petiolulate, oblong-elliptic, 25 ecm. long or less, acuminate, rounded 
or subcordate at base, entire or sinuate-serrate, glabrate; panicles about 20 cm. 
long; calyx about 1.5 cm. long; corolla 4.5 to 5 cm. long; fruit 20 to 30 cm. long, 
2.5 cm. wide, longitudinally ridged and irregularly tuberculate. ‘‘ Primavera”’ 
(Colima); ‘‘cortez,” “‘cortez blanco”’ (El Salvador). 

The wood is exported from Mexico for veneering and cabinet work, and is 
reported to be known in trade as ‘‘white mahogany.”

or glabrate; calyx 5 to 6 mm. long; corolla 6.5 to 8 em. long; fruit about 35 cm. 
long and 1.5 cm. thick, smooth. ‘‘Amapa’’ (Sonora, Sinaloa); ‘‘roble’’ (Guer- 
Tero); ‘“‘amapa prieta,”’ ‘‘amapa rosa” (Sinaloa). 

The wood is said to be brown, with red lines, and very handsome, heavy, 
rather hard, resistant, taking a good polish, and durable when exposed to mois- 
ture. It is much used locally for building purposes and for cabinet work. A 
violet ink is said to be made from it.

Slender shrub or tree, sometimes 9 meters high, with a trunk 30 em. in di- 
ameter, the trunk short, the bark thin, irregularly ridged, scaly; leaves opposite 
and alternate, linear, 10 to 30 em. long, attenuate to each end, entire, pubescent 
or glabrous; flowers purplish or white, in terminal racemes or narrow panicles; 
calyx bilabiate, 5-dentate; corolla 2.5 to 3.5 cm. long, somewhat bilabiate, 5-

specific gravity about 0.59. ‘‘Mimbre”’ (Zacatecas, Chihuahua, Nuevo Leén, 
Durango). 

The tree grows most commonly along arroyos. It is often planted because of 
its showy sweet-scented flowers. In the United States it is known as ‘desert 
willow” or “flowering willow,” the leaves bearing a strong resemblance to those 
of some species of willow (Salix). The wood is sometimes used for fence posts 
and the tough slender branches for making baskets. A decoction of the flowers 
is employed locally for coughs and as a stimulant in cardiac diseases, and the 
dried flowers are often sold in the markets for these purposes.

Tree, 4.5 to 9 meters high, the branches armed with short stout incurved 
spines; leaves glabrous, long-petiolate, the petiole naked or narrowly winged, 
the leaflets elliptic, ovate, or obovate, 3 to 8.5 cm. long, acute or abruptly attenu-

Campeche, Sinaloa, Costa Rica, El Salvador, Guatemala; from the Nahuatl 
cuau-xilotl) ; ‘‘gueto-xiga’”’ (Oaxaca, Zapotec, Reko). 

The tree is often cultivated for its shade and fruit. The fruit is sweet and 
edible, and is eaten either raw or cooked. It is sometimes made into pickles or 
preserves and also roasted in ashes. Stock of all kinds are fond of it. It is 
considered a good remedy for colds; the roots are used as a diuretic, especially 
in the treatment of dropsy, and the juice of the leaves was formerly, at least, 
dropped into the ears as a cure for deafness. The flowers are greenish white or 
greenish yellow, and the fruit green tinged with yellow. 

The name Crescentia edulis Desv. has no connection with Parmentiera edulis 
DC., and it is not certain that Desvaux’s name relates to the present plant. He 
describes the leaves as simple, but his description of the fruit points to Parmen- 
tiera edulis.

The calabash tree is a common plant of southern Mexico, noteworthy because 
of its large fruits, many of which are borne close to the trunk. The seeds are 
sometimes cooked and eaten. The pulp is much used in domestic medicine and 
is said to have emollient, expectorant, laxative, and astringent properties. It 
is employed chiefly as a healing agent for wounds and as a remedy for disturb- 
ances of the respiratory system. The fruit is often eaten by cattle during the 
dry season, but it is said that it often produces abortion. Seemann states that 
the sap was employed in Panama for dyeing silk black. The wood is of little 
value, but is often used for various purposes. The hard shell of the fruit, which 
resembles a gourd, has been used in Mexico from ancient times for making 
“jicaras” or drinking cups, which are often ornamented by carving and painting. 
Vessels thus made are sufficiently substantial for moderate use over fire.

The wood is used locally for making wagons and other articles. The flowers 
have a strong unpleasant odor. The fruit is employed in domestic medicine Jike 
that of C. cujeie, and the roots also are used medicinally. The pulp is sweet, since 
it contains much sugar, and is said to be fermented sometimes to obtain alcohol- 


STANDLEY—TREES AND SHRUBS OF MEXICO 1325 


A decoction of the leaves is reported to be used for promoting the growth of the 
hair. In Nicaragua a cooling drink is made from the seeds. The shells of the 
fruits are much used for making cups, as in the case of Crescentia cujete. 

The earliest account of this species and of C. cujete is that given by Oviedo (Lib. 
VIII, Cap. IV), part of which is translated below. The leaves which resemble a 
cross are, of course, those of C. alata, in which the resemblance is very striking, 

“The Higiiero is a large tree like the mulberry trees of Castile. It is a kind of 
calabash, round or somewhat elongate; and the round ones are very round, of 
which the Indians make cups or other vessels, for drinking. _The wood is strong 
and good for chairs and other purposes. It is flexible and strong, and when 
worked resembles in grain pomegranate or hawthorn. The leaf of this tree is 
long and narrow, and the widest part is at the tip, from which it narrows to the 
base where it is attached, as I sketch it here. In times of scarcity the Indians 
eat this fruit. I refer to the interior—which is like a green calabash. When 
dried and the interior removed, to make a vessel of the higtiera, the vessel has a 
luster like a gourd, and indeed it is a gourd of the sort I have described. These 
fruits or calabashes are so large that the larger ones are like a water-jar that 
holds a gallon of water, and some are no larger than a closed fist; and thus they 
make of them vessels of the size that the dimensions permit. These trees are 
common in Hispaniola and all the islands of these Indies and in the Spanish 
Main. * * * TIwmay state that the leaf of the higtero is long and narrow, and 
the widest part is near the tip, from which it narrows to the base where it is 
attached, as I said above, and this is seen plainly in plate 3, figure 3. But there 
are other higtieros in Tierra-Firme which are different, not in the fruit or in any 
other particular I have mentioned, but only in the leaves, as shown in plate 3, 
figure 4, each leaf in the form of a cross, as I have drawn it; and this seems to me 
a very noteworthy thing, in which appears a testimony of the cross, a thing of 
which these people can not have been ignorant. These higtiero trees, which have 
the leaves all formed like crosses, I have seen in the Province of Nicaragua, 
especially in Negrando, where lies the city of Leén, and in other parts of that 
country; and marveling upon the leaves, I gathered some to show in Spain, as 
I did show them, and I still have some in my possession. But in Nicaragua, 
where as I have said there are many of these trees, they call the tree guacal. The 
precious vessels of the higtieros are found in Darién and in the Gulf of Uraba, 
with handles of gold, and so handsome that the most powerful king might drink 
from them without reproach. And these come through the channels of trade 
from the great river of San Juan, which empties into the Gulf of Uraba.”’

This plant is well known in Mexico and nearly throughout Central America. 
The leaves are placed in hot water, which at first assumes a dingy blackish color 
but later becomes dark blue. This solution is employed by laundresses for 
whitening clothes, in the same manner as indigo. The plant was employed for- 
merly in Mexico also as a dye. It is used as a remedy for dysentery, fevers, 
gonorrhoea, and other affections.

153. RUBIACEAE. Madder Family. 


Shrubs or trees, or often herbs, sometimes armed with spines; leaves opposite 
or verticillate, entire, stipulate; flowers perfect or unisexual, large or small, 
usually regular; calyx inferior, the limb entire or lobate, rarely obsolete; corolla 
gamopetalous, the lobes valvate, imbricate, or contorted; stamens usually as 
many as the corolla lobes and alternate with them, inserted on the tube or throat 
of the corolla; style simple or 2 to 10-cleft; fruit capsular, baccate, or drupaceous, 
or of dehiscent or indehiscent cocci. 

Numerous genera of the family are represented in Mexico only by herbaceous 
species. Among the most important members of the family are the species of 
Cinchona, a South American genus, which yield the Cinchona bark of commerce, 
from which quinine is extracted. Two or more species of Cinchona are cultivated 
in Veracruz, and perhaps elsewhere, having been introduced first at Cordoba.

Type collected between La Venta and Niltepec, Oaxaca. Also in El Salvador. 
Large shrub or tree; leaves slender-petiolate, rounded-ovate or rounded-oval, 

20 to 30 cm. long, 16 to 25 cm. wide, short-acute or acuminate, cordate at base, 

minutely puberulent beneath upon the nerves; flowers in terminal panicled cymes, 

mostly sessile; corolla broadly funnelform, 4 to 5 mm. long; filaments long- 
exserted. ‘‘Brasil,” ‘‘limpia-dientes”’ (El Salvador). 

The exact position of the genus within the family is somewhat doubtful because 
of the lack of mature fruit. The wood turns red upon exposure to the air.

Shrub, 1 meter high or less, or sometimes herbaceous; leaves sessile or short- 
petiolate, acute to long-attenuate, hirtellous, scabrous, or glabrate; cymes 
usually few-flowered; corolla red, the tube 15 to 32 mm. long. ‘‘Trompetilla”’ 
(Hidalgo, Mexico, Veracruz, Oaxaca); ‘‘tlacoxochitl,”’ ‘“‘tlacosuchil’’ (Nahuatl; 
“‘trumpet-flower’’); ‘‘mirto’’ (Coahuila, Durango); ‘‘mirto del campo” (Du- 
rango); ‘‘hierba del pasmo”’ (Sinaloa); ‘‘contrayerba”’ (Mexico); ‘‘doncellita’”’ 
(Oaxaca, Reko); “‘hierba del indio”’ (Sinaloa). 

A handsome plant and, like some of the other species, often cultivated. It is 
employed locally as a remedy for dysentery and hydrophobia and other affections. 

Dr. Reko states that the ancient Mexicans were accustomed to begin the 
treatment of a disease by bleeding, which was induced by provoking hemorrhage 
from the nose with powder of ‘“cebadilla’’ (Stenanthium frigidum); and to 
restrain excessive hemorrhage they used the powdered roots of the tlacoxochitl. 

The plant is described and figured by Herndndez.! It is probably also the 
one mentioned by Sahagtin under the name tlacoxochitl. The latter author 
says: “The flavor of the roots is both bitter and sweetish. They are good for 
heat and exhaustion of the heart. Ground with about 15 grains of maize and 
as much cacao, and mixed with water, they should be taken several times on an 
empty stomach or after meals.”

“irayol”’ (Guatemala, El Salvador); ‘‘tapaculo,” “yigualti,” “gigualti’’ (Nica- 
ragua); ‘“‘tifie-dientes”’ (El Salvador). 

The typical form of the species is glabrous. The form occurring in Mexico is 
G. americana caruto, which is distinguished by its copious pubescence. 

The wood is said to be soft but strong and resistant, flexible, fibrous, whitish 
tinged with gray; its specific gravity is reported as ranging from 0.73 to 0.87. 
It is used for carts, gun-stocks, axe handles, and other articles. The bark is 
said to be rich in tannin and it has been employed for tanning. A gum is pro- 
duced from incisions in the trunk. The leaves are eaten by cattle. 

The fruit is brown or green tinged with brown, with a leathery skin and scant 
acid pulp. The copious juice colors everything it touches brownish or blackish 
violet. The pulp is eaten by domestic animals and also by human beings, and 
is used in the preparation of a refreshing drink, and has been fermented to 
produce an alcoholic beverage. The juice was much used by the early inhabit- 
ants of tropical America for coloring cloth and utensils and for painting the 
skin. A decoction of the roots was formerly employed in the West Indies as a 
remedy for gonorrhoea, and in El Salvador the fruit is considered a remedy for 
jaundice. 

The earliest account of the tree is that of Oviedo (Lib. VIII, Cap V), who 
speaks of it as follows: ‘‘The Xagua is a handsome large tree, and I have seen 
made of it fine lance handles, as long and thick as were wanted; it is a heavier 
wood than ash, and very common in Hispaniola and other islands and in the 
Spanish Main. They are high straight trees like the ashes, beautiful to see, and 
the handles made from them are of pretty complexion, and in color pale brown 


1372 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM 


totawny. In Hispaniola, although there are some of these trees, they are neither 
sO numerous nor so well suited as in Tierra-Firme, in the Province of Cueva or of 
Castilla del Oro, for the making of lances. They produce a fruit as large as a 
poppy pod, and very similar except in the crown, which the Xagua does not have. 
It is good to eat when ripe and seasoned; from it is obtained a clear juice with 
which the Indians bathe their limbs and sometimes the whole body, when tired. 
And also for their pleasure they paint themselves with the juice, which, aside 
from being astringent, turns everything it touches as black as fine and polished 
jet, or even blacker; and this dye can not be removed for 15 or 20 days or more; 
and often the nails are black until they are renewed if they are wet in the juice; 
all of which I have seen many times. * * * They are accustomed to play a 
joke upon the women, wetting them carelessly with Xagua juice mixed with 
other scented ones; and after a little there come out spots over their bodies, 
and the women, not knowing the cause of the spots, are frightened into seeking 
a remedy for them; and the remedies are harmful, and likely to burn or blister 
the face and body where the spots are but not to remove them until the passage 
of the 20 days, as I have said above, when little by little the dye disappears. 
When the Indians of Tierra-Firme prepare for battle, they paint their bodies 
with Xagua and with Biza, which is a red dye. And the Indian women also 
when they wish to appear well decorate themselves with one or both colors; 
but to my eyes they appear little better than devils when they are thus adorned.”

“Café.” 

Coffee is grown in most of the warmer regions of Mexico and it is one of the 
important agricultural products of the country. The most important states in 
coffee production are Veracruz, Chiapas, Oaxaca, and Tabasco, but Veracruz is 
reported to produce a larger amount than all the other states combined. The 
shrub is said to have been cultivated first at Cérdoba. It is reported to be 
abundant in the wild state in some parts of Veracruz. 

Coffea liberica Hiern, the Liberian coffee, also is cultivated in Mexico. It is 
distinguished by having a 6 to 8-lobed corolla. It can be grown at lower levels 
than C. arabica, and is more robust and productive.

Shrubs or trees; leaves pinnate or bipinnate, the leaflets serrate; flowers small, 
white, in terminal flat-topped cymes; calyx 3 to 5-dentate; corolla rotate, 3 to 
5-lobate; fruit a small drupe, containing 3 to 5 1-seeded nutlets. 

The English name for plants of the genus is “elderberry.’”’ The fruit of all 
species is edible and is often used in the United States for pies and for making 
wine. The stems contain a large amount of pith. A decoction of the stems is 
employed by some of the Indians for dyeing baskets black. In Europe the 
leaves and flowers have been used for dyeing leather yellow, and the bark or 
wood, with alum and iron salts, for dyeing green or brown. In Germany oil 
has been extracted from the seeds, and the flowers are used to flavor wine. 

The flowers of S. canadensis L. were formerly official in the United States 
Pharmacopoeia, and those of the Old World S. nigra L. are now official in some 
of the European pharmacopoeias. They have gently excitant and sudorific 
properties. The fruit is diaphoretic and aperient and has been used as an 
alterative in treating rheumatism and syphilis. The inner bark is a hydragogue 
cathartic and in large doses emetic. It has been employed for dropsy and 
epilepsy.

southern California; Central America. 

Tree, sometimes 10 meters high, with a trunk 30 cm. in diameter, the bark 
thick, gray, scaly; leaflets usually 5, ovate to ovate-lanceolate or oval, 3 to 12 
cm. long, short-acuminate, pale; cymes 6 to 20 em. broad; corolla 5 to 8 mm. 
broad; fruit about 6 mm. in diameter, nearly black; wood soft, coarse-grained, 
brownish, its specific gravity about 0.46. Usually known in Mexico as “‘satico’’; 
“azumiatl” (Veracruz); ‘“cumdemba,’’ “cumdumba”’ (Tarascan); ‘‘xumetl”’ 
(Urbina); ‘“nttzirza’’ (Otomi); “‘bixhumi’’ (Oaxaca, Zapotec, Reko); “yutnu- 
cate”’ (Oaxaca, Mixtec, Reko); ‘“‘shiiksh’”’ (Mixe, Belmar); “‘coyopa”’ (Zoque, 
Gonzales). 

The fruit is used in Mexico for various purposes. Some of the Indians of 
southern California dried it for winter use. The flowers have a heavy odor. 
They are used medicinally in Mexico, and other parts of the plant are used much 
as described above. The leaves are sometimes bound upon the forehead to 
relieve headache. 

Sambucus mexicana bipinnata (Schlecht. & Cham.) Schwerin! is a form with 
bipinnate leaves. It was described from Jalapa, Veracruz.

Herbs, shrubs, or trees, sometimes scandent; leaves opposite or alternate, 
rarely whorled, entire to dissected, never truly compound; flowers collected in a 
head (this rarely 1-flowered) on a receptacle, surrounded by an involucre of 
phyllaries (bracts); corolla gamopetalous, regular, tubular, and 5-toothed (rarely 
2 to 4-toothed), bilabiate, or ligulate (flattened, strap-shaped, and usually 2 to 
5-toothed), rarely wanting in the pistillate flowers; stamens (in the hermaphrodite 
or staminate flowers) almost always 5, united by the anthers or rarely free, insert- 
ed on the corolla; ovary inferior, 1-celled, with an erect anatropous ovule; style 
usually 2-branched, the branches stigmatiferous inside, often bearing sterile 
appendages at apex; fruit an achene, with a single erect exalbuminous seed, often 
bearing a pappus of bristles, awns, or scales.—The corollas are of 4 chief sorts,

ligulate or strap-shaped, bilabiate, tubular, and filiform. Heads composed of one 
kind of flowers only are called homogamous, those composed of two or more kinds 
heterogamous; when heterogamous, the central flowers (disk) are always herma- 
phrodite, the peripheral pistillate or neutral (lacking the style). Homogamous 
heads in which all the flowers are hermaphrodite and have ligulate (in this case 
always 5-toothed) corollas are called ligulate; homogamous heads in which all the 
corollas are tubular and hermaphrodite or staminate, or filiform and pistillate, 
are called discoid. Heterogamous heads in which the peripheral corollas are 
ligulate are called radiate; those in which the peripheral flowers are pistillate, 
with tubular, filiform, or abortive corollas are called disciform. The receptacle 
may be naked, bristly, or paleaceous (bearing pales or chaff). The generic 
characters are drawn to a considerable extent from the character of the pappus, 
which may be of bristles, awns, scales, or teeth, or reduced to a crown or cup, or 
entirely wanting.

Herbs, shrubs, or trees, with alternate leaves and small to large, usually purple 
heads; involucre cylindric to hemispheric, the phyllaries graduated, dry or indurate’ 
rarely with herbaceous tips; flowers 1 to very numerous, all tubular, hermaphro- 
dite, fertile; receptacle naked; anthers sagittate at base; achenes 4 to 10-ribbed, 
sometimes with an apical callous border; pappus biseriate, the outer much 
shorter, subpaleaceous or rarely setose, the inner setose. 

The root of Vernonia nigritiana Oliver & Hiern of West Africa is said to be 
employed as a febrifuge, antidysenteric, and emetic, and to resemble somewhat 
ipecac in its therapeutic properties. It contains a glucoside, vernonin, which is a 
cardiac poison comparable to digitalin, but less active.

Veracruz, Puebla, Michoacdn, and Mexico; type from the valley of Toluca. 
Central America. 

Described as shrubby, but apparently a scarcely lignescent perennial herb, 30 
to 60 em. high, copiously spreading-pubescent, the trichomes moniliform with 
dark purple nodes; stems terete, with white pith; leaves suborbicular-ovate, 
acuminate, serrate, obtuse to rounded or distinctly cordate at base, softly mem- 
branaceous, 3 to 8 cm. long, 2.5 to 6.5 em. wide; petiole 1 to 3 cm. long; corymbs 
compound, terminal, often 30 em. broad; heads 20 to 40-flowered; phyllaries 
linear, subscarious, lacerate-ciliate toward tip; corollas white or nearly so, hispid

Specimens apparently belonging to this species have been confidently referred 
by Schultz-Bipontinus (in herb.), Klatt (in herb.), and Hemsley (Biol. Centr. 
Amer. Bot. 2: 93. 1881) to the earlier and little known E. ciliatum Less., but the 
latter species is shown by its type to have smaller, relatively shorter-petioled 
and more incisely toothed leaves with a short but sharp basal acumination. It 
is described by Lessing (Linnaea 6: 404. 1831) as herbaceous and as having 
glabrous corollas.

Hebeclinium liebmanniae Hook. f. & Jacks. Ind. Kew. 1: 1097. 1893, by error. 

Veracruz; type from Mirador. 

Shrub with slender terete flexuous branches, finely tomentellous or incurved- 
puberulent; leaves opposite, ovate, slender-petioled, acuminate, sharply serrate, 
palmately 3 or 5-nerved from near the base, membranaceous, green and smoothish 
on both surfaces; heads 35 to 40-flowered, in compound leafy-bracted panicles; 
phyllaries lanceolate to lance-oblong, acute. 


DOUBTFUL AND EXCLUDED SPECIES. 


Conoc.Linium (Eupatorium) aLtBuM Mart. Linnaea 24: 194. 1851. Described 
from greenhouse material of Mexican origin and said to be a smooth half-shrub 
with somewhat deltoid acuminate serrate leaves, 3 to 5-headed corymbs, 24 to 
30-flowered heads, and pappus of 13 bristles. The species is wholly obscure and 
in any event the name under Eupatorium'is unvailable, owing to the earlier and 
still valid homonym. 


EUPATORIUM KARVINSKIANUM DC. Prodr. 5: 163. 1836. De Candolle, de- 
scribing this species from very fragmentary material, supposed it to be shrubby. 
Later specimens secured by Pringle and others seem to show it herbaceous 
throughout, and one collected by Galeotti is indicated on his label as an annual. 
It is therefore omitted from the foregoing treatment. 


EUPATORIUM MICRANTHUM Lag. Gen. & Sp. Nov. 25. 1816. This wholly 
obscure plant, to judge from its blue florets, imbricate phyllaries, and the few 
other remarks regarding it, was presumably an Ageratum. There seems no satis- 
factory ground for applying the name, as did Lessing (Linnaea 5: 138), to a 
white or pink-flowered Hupatorium of Section Eximbricata. Lessing’s E. mi- 
cranthum must therefore receive the next later designation, namely E. ligustrinum 
DC. Prodr. 5: 181. 1836.

1881. Conoclinium oligolepis Kunze, Del. Sem. Hort. Lips. 4: 2. 1840. Vaguely 
characterized and wholly obscure species, raised from Mexican seed in the 
Botanical Garden at Leipzig. Said to have been suffruticose, with erect sulcate 
pubescent stem, opposite, petiolate, deltoid-ovate, obsoletely sinuate-dentate, 
pubescent leaves, short-pediceled heads in contracted terminal corymb, and 
15 to 20 subserial phyllaries. 

EUPATORIUM PAPANTLENSE Less. Linnaea 6: 403. 1831. This species incom- 
pletely described by (briefly and for the most part negatively stated) comparative 
characters is still doubtful. It may have been only a form of the earlier £. 
havanense H. B. K., to which in any event it seems to have been closely related.

character and tracing of type, this can not with certainty be separated from

Chihuahua to Nuevo Leén; Baja California. Western North America, 
type from the plains of the Missouri. 

Suffrutescent or suffruticose, hirtellous-puberulent, bushy-branched, 40 em. 
high or less; leaves linear-filiform, 2 to 4 em. long, 1 mm. (rarely 1.5 mm.) wide

‘‘Hierba de San Nicolds’’ (Nuevo Leén); ‘‘hierba de vibora,”’ “‘coyaye’’ (New 
Mexico). 

A decoction of the plant is reported to be used in New Mexico as an emmen- 
agogue and as a remedy for gastric disturbances. In the southwestern United 
States this and related species are known variously as ‘‘ yellow-weed,’’ ‘‘brown- 
weed,’ ‘‘sheep-weed,”’ ‘‘broom-weed,’’ and “snake-weed.’”’ The plants are 
often very abundant upon the plains, and their abundance usually indicates 
that the land has been over-grazed, especially by sheep.

not well agree with any Mexican species, however, and Gray identifies it with 
much probability with the Chilean plant later described as Brachyris paniculata 
DC.

In the Bahamas the shrub is called ‘‘sour-bush.’”’ The flowers are said to be 
a source of honey. In Tamaulipas an infusion of the leaves in alcohol is applied 
externally to relieve neuralgia and rheumatism. Seler reports that in Yucatan 
the leaves are heated and applied hot as a hemostatic, while in the same State 
the plant is employed as a febrifuge and emmenagogue. Descourtilz states 
that in the West Indies the plant was used as a remedy for the bites of venomous 
animals and that a decoction of the leaves was taken as a remedy for stomach 
affections.

Coahuila and Durango to Zacatecas and San Luis Potosi. Texas; type from 
Escondido Creek. 

Shrubby, up to 1 meter high, much branched; branches silvery-strigillose; 
petioles 0.5 to 2.5 em. long; blades lanceolate to lance-ovate, 1 to 4.5 em. long, 
0.3 to 2.56 em. wide, acute or acuminate, acute at base, coarsely few-lobed to 
entire, silvery-canescent; heads several, in small long-peduncled cymes or 
cymose panicles, short-pediceled, about 6 mm. wide; pappus of 2 divergent or 
erectish awns about 1 mm. long. ‘‘Guayule”’ (the most common and widely 
distributed name); ‘“‘hierba del hule” (Durango); ‘‘tatanini’’ (Otomf); ‘“hierba 
blanca,” “hierba ceniza”’ (Querétaro); ‘‘hule’’ (Zacatecas, Chihuahua); ‘‘copa- 
llin,” ‘‘afinador”’ (Lloyd); ‘‘xihuite,” ‘“jihuite” (Zacatecas). 

According to Patoni, the name “guayul” or “‘guauyul,”’ of which guayule is a 
variant, belongs properly to Vauquelinia corymbosa (see page 323), and became 
applied through some error to this plant. 

The guayule rubber plant is one of the most important members of the Mexican 
flora. Its stems yield a high percentage of rubber, a fact well known to the early 
inhabitants. From the plant was obtained the rubber for making the large balls 
used in the game of pelota, a game of very ancient origin. 

Attempts at industrial exploitation of the plant began in Zacatecas as early 
as 1892 or 1893, and shortly afterward in San Luis Potosi, but these were not 
successful financially on account of the lack of suitable apparatus for the extrac- 
tion of the rubber, and because of the absence of a market. About 1904, when 
much capital from the United States had been invested in the industry, it became 
of importance and large factories were established for the treatment of the plant. 
The raw plant rose to a price of $75 per ton. In 1911 the outlay of North Ameri- 
can capital alone in the industry was said to be $30,000,000, and between July 1, 
1905, and July 1, 1909, about 32,000,000 pounds of guayule rubber were imported 
into the United States, this being about 80 per cent of the total export. Later 
the industry declined, partly because of a failure in supply, but chiefly on account 
of the competition of East Indian rubber.

This plant furnishes rubber like that of guayule, but in smaller amounts. 
It has been employed extensively in Mexico for the extraction of commercial 
rubber, and was known also to the aboriginal inhabitants. Children sometimes 
chew the stems to obtain the rubber for making balls. In Coahuila the plant is 
reported to be used as a domestic remedy for affections of the liver.

Nahuatl! cihua-patli, woman-+ medicine); “‘singuapacle,’’ “‘zuapatli,” ‘‘zoapatle,”’ 
‘‘7ihoapactli,”’ “‘sinhuapastle,”’ ‘‘zihuapatl,” ‘‘zoapatle,’’ ‘‘cihoapactli,” “hierba 
de la parida”’ (Distrito Federal). 

The plant is reputed to have stomachic, diuretic, and pectoral properties. Its 
most common use, however, is as an aid to women in childbirth, the decoction 
being administered to provoke uterine contractions, although such use is said to 
be dangerous. It is said to be much used for this purpose in Mexico at the present 
time. See E. Armendariz, Estudio quimico del zoapatli, Anal. Inst. Méd. Nac. 
Méx. 1: 11. 

It is doubtless this or a related species of which Sahagtin writes as follows: 
“There is a medicinal plant called ciuapatli. It is a shrub from which spring many 
long branches with ashen, pointed leaves. The flowers are yellow and white. 
The seed resembles that of blite. The decoction of the leaves is the part used. 
Pregnant women drink it at the time of delivery to facilitate labor and to prevent 
consequent exhaustion. The numerous roots of this shrub are fine and long, 
black outside and yellow within. Ground and mixed with lukewarm water,

on an empty stomach or after meals. Those who make use of it should be careful 
of their diet. This plant grows in the fields, on the mountains, or even in the

Guanajuato to Mexico; type from Mexico, without definite locality. 

Shrub up to 2.5 meters high, much branched; leaf blades lance-ovate to tri- 
angular-ovate, 1.5 to 7 cm. long, entire to coarsely toothed; heads 7 to 12 mm. 
wide, numerous in cymose panicles; phyllaries lance-ovate to ovate, mostly 
acutish. ‘‘Caxtidani’? (Querétaro); ‘‘cenicilla;’ ‘‘limpia-tunas’’ (Mexico, 
Oaxaca). 

The name “‘limpia-tunas”’ is said to be given because of the fact that the plant 
usually grows with prickly-pears, and the branches are used as brushes for re- 
moving the fine spines from the tunas. The plant is said to have the odor of 
southernwood (Artemisia abrotanum).

lanceolate, acute to acuminate; corollas white, turning greenish when old. 
‘‘Hierba de San Antonio”’ (Puebla, Veracruz); ‘‘duerme-boca,”’ ‘‘salta-afuera”’ 
(El Salvador); ‘‘oreja de conejo”? (Honduras); ‘‘tabacén,’’ ‘‘bejuco de muela”’ 
(Porto Rico). 

The root of this plant, when chewed, is said to deaden all sensation in the 
tongue, hence the name “‘duerme-boca” applied in El Salvador. The name 
‘‘bejuco de muela,’’ reported from Porto Rico, would indicate that because of 
this property the plant is employed there as a remedy for toothache. The name 
‘‘salta-afuera’’ used in El Salvador is an allusion to the fact that the vine is used 
there as a fish poison or barbasco, as which it is reported to be unusually efficient.

The plant is bitter and has a strong but rather agreeable odor. It is much 
used in domestic medicine, aphrodisiac, antispasmodic, sudorific, and diuretic 
properties being ascribed to it. It is used especially in the treatment of fevers 
and rheumatism.

ADDITIONS AND CORRECTIONS. 


In the several years that have passed during the publication of 
the various parts of this volume, there have appeared descriptions 
of a rather large number of new species of Mexican trees and shrubs. 
Although it is not feasible to include these in the keys to species, it 
has seemed desirable to enumerate them. It has been possible to 
examine authentic material of a part of the new species, and in some 
cases such examination has resulted in their being recognized at 
once as synonymous with earlier published species. In the case of 
species described in some of the larger or more critical genera the 
writer has made no attempt to determine their validity, therefore it 
is not to be assumed that all the additional species listed here are 
considered valid by the writer. 

There are included also in this appendix additional vernacular 
names gleaned from several sources. The greater part of them have 
been obtained in connection with the identification of extensive 
collections made in the States of Sinaloa and Nayarit by Sr. Jesis 
G. Ortega. There have been accumulated a large number of ad- 
ditional vernacular names as a result of recent explorations in 
Central America, but it has not appeared necessary to list them here, 
since they will be enumerated in a flora of Central America now in 
course of preparation. 

Corrections of typographical errors have been made only in the 
case of a few which are not obvious. In a work of such extent some 
typographical errors*are bound to occur, but most of them will be 
recognized at once as such. 

The number of species of Mexican trees and shrubs recognized as 
valid in the present volume is approximately 5,700. There is no 
doubt that this number will be greatly increased by further ex- 
ploration in Mexico. 


CYATHEACEAE. 

Page 41. Dr. Reko states that in Chinantla, Oaxaca, Cyathea princeps is 
known as ‘‘rabo de chango,” ‘‘rabo de mico,” ‘‘rabo de mono,” and “‘rabo de 
machin.” 

PINACEAE. 


Page 51. The Nahuatl term for pine tree is ‘“o¢o-cuahuitl,”’ which is said to 
signify “torch tree.’’ The following names are reported in literature for unde- 
termined species of Pinus: ‘‘Tzivireni” (Michoacan, Ramirez); ‘‘pizomlab”’

(Huastec, Asiain); “‘tziin,’”’ ‘‘tzinkiup” (tree), “‘tzinuapk”’ (resin), “poptzin

catepetl as “‘tlacocote” (Gadow). 
(1643) 


1644. CONTRIBUTIONS FROM THE NATIONAL HERBARIUM 


Page 56. Pinus teocote. The Aztec name, ‘‘xal-ocotl,” signifies ‘‘sand pine; ’”’ 
the name ‘‘teocote,” ‘‘pine of the gods.’’ Robelo states that this name was. 
given because of the fact that only the nobles were permitted to use the resin as. 
incense. 

Page 58. Pinus patula. The term for the cones is “huajolote”’ or ‘‘guajolote,’’ 
from ‘‘quaholotl,’’ ‘woody ear (of corn).’?’ The name ‘‘ocote macho”’ is said to 
be applied to this species. 

To the species of Pinus listed should be added the following: 

Pinus muricata Don, Trans. Linn. Soc. Bot. 17: 441. 18387. A California. 
species, represented in northern Baja California and on Cedros Island by var. 
anthonyi Lemmon (Handb. West. Amer. Coneb. 43. 1895). 

Pinus radiata Don, Trans. Linn. Soc. Bot. 17: 442. 1837. A California. 
species. Var. binata Lemmon (West Amer. Coneb. 42. 1895) is reported from 
Guadalupe Island, Baja California. 

Page 59. Abies religiosa. This tree occurs also in Sinaloa, where it is known 
as ‘“‘cahuita;’’ in Guerrero it is called ‘‘hoja petate.”’ Sahagtin states that the 
nobles and rich men at certain seasons of the year decorated the doors of their 
dwellings with fir branches. Robelo states that when the priests sacrificed them- 
selves by piercing various parts of their bodies with maguey spines, they carefully 
collected the blood upon fir branches. The branches were used by the Aztecs for 
making brooms, and are still employed thus in some localities. 

Page 63. Cupressus benthamii. By European botanists this is regarded as a 
form of C. lusitanica Mill. (Gard. Dict. ed. 8. Cupressus no. 3. 1768), or as a 
synonym of that species. It is probable that the Mexican tree was carried at 
an early date to Portugal (hence the specific name), where it has since been in 
cultivation. It seems necessary, therefore, to adopt Miller’s misleading name for 
the Mexican species. In Sinaloa the tree is known as ‘‘tdscate.”’ 

To the listed species of Cupressus should be added the following: 

Cupressus forbesii Jepson, Madrofio 1:75. 1922. Northern Baja California

The fiber is known as “‘ixtle de palma.’”’ The fruits are eaten raw or couked with 
sugar, and pigs are said to be fond of them. The flowers also are cooked and 
eaten. The names ‘‘palma china,” ‘palma de aparejo,”’ and “palma de suda- 
dero”’ reported by Endlich under Yucca valida probably pertain to Y. australis. 

Page 94. Yucca macrocarpa. ‘ Palma’’ (Chihuahua). 

Yucca mohavensis. By the Coahuilla Indians of California the fiber of the 
leaves was employed for weaving and for making sandals and saddle mats. 
The green fruit was roasted over coals and eaten. The ripe fruit is sweet but 
slightly astringent, and was eaten raw.

AMARYLLIDACEAE. 


Page 107. A descriptive account of the genus Agave has been published by 
Berger (Die Agaven. Jena, 1915). On account of conditions resulting from the 
war, this was received in the United States too late for the inclusion of the data 
in the Trees and Shrubs of Mexico. 

The following names are reported, relating to species of Agave whose identifica- 
tion is uncertain: ‘‘Ehpuqua” (Michoacdn, Tarascan); ‘‘benal” (leaf), “boc” 
(pulque), ‘‘itzi,’ ‘‘tzim’”’ (Huastec, Asiain); “keihnoo,” ‘keitz,” ‘‘keitznoo”” 
(pulque), ‘‘tzaktz” (Mixe, Belmar); ‘‘acamba,”’ ‘“‘atieni’’ (aguamiel), “‘orori’’ 
(Tarascan, Ledn); ‘“‘guada”’ (Otomi, Buelna). 

Page 117. Agave karwinskii. Dr. Reko states that this species is known in 
Oaxaca as “espadilla,’’ and bears the Zapotec names ‘‘bixuexe”’ and “‘toba- 
siche.” It is cultivated commonly along hedges and produces a superior class 
of mescal. 

Page 119. Agave tequilana. Endlich reports that this furnishes ‘“‘ixtle de 
Tequila,” “‘ixtle de mescal,” and “‘jarcia.” It is called also ‘‘maguey de Tequila 


and ‘‘maguey mezcal.”’ ‘

The leaves and stalks are eaten after having been cooked for one or two days 
in pits in the sand. The flowers also are eaten, and are sometimes dried for use 
in winter.

DIOSCOREACEAE. 


Page 144. Dioscorea macrostachya. In a recent monograph of the genus 
Dioscorea, Testudinaria cocolmeca is referred definitely by Knuth (in Engl. 
Pflanzenreich IV. 48: 164. 1924) to synonymy under this species. The root 
of the plant is a large hard tuber, partly above ground, its covering consisting 
of a thick dark coat that is broken into numerous polygonal plates. Dr. Reko 
has furnished the following information with regard to the plant: ‘‘Bejuco de 
coraza,” ‘“cocolmecatl.”” The young fleshy asparagus-like shoots contain an 


STANDLEY—TREES AND SHRUBS OF MEXICO 1647 


albuminous juice that is used in the preparation of pozonque, a delicious and very 
nutritious refreshment, made of ground chocolate, mashed soft corn, and this 
juice, beaten into a light foamy mass. The ground starchy matter of the 
enormous rhizome is used as a barbasco, for stupefying fish. It probably contains 
the same alkaloid, dioscorine, that has been found in other species.

Page 158. Populus angustifolia. The Gosiute Indians of Utah use the 
young shoots of this species for basket making. A kind of honey dew produced 
on the under side of the leaves by aphids is gathered and used in much the same 
way as sugar. 

Populus monticola. A synonym is Populus brandegeei Schneider, Ill. Handb. 
Laubh. 1: 23. 1904. It is probably this species of which Clavigero writes 
(Historia de la California, 1789): ‘‘The guaribo, the largest tree of California, 
is so like the cottonwood [dlamo, of Spain] that at first glance it can not be dis- 
tinguished; but nevertheless it is quite different in the quality of the wood, which 
is very good for rafters and all kinds of construction. Unfortunately, this tree 
grows only in a few rugged and almost inaccessible places, like the pines in the 
southern part of the peninsula.” 

Page 159. Populus dimorpha. ‘‘ Alamo,” ‘“‘chopo”’ (Sinaloa). 

Populus arizonica. The Pima Indians of Arizona formerly ate the fresh catkins 
of this and related species, stripping off the flowers between the teeth. 

Page. 160. The following names are reported for undetermined species of 
Salix: ‘‘Tocoy”’ (Huastec, Asiain); ‘‘hoo-cuy’’ (Zoque, Gonzales); ‘‘xitzo”’ 
(Otom{i, Buelna). By some of the North American Indians willow bark was 
smoked like tobacco. The Chiricahua Indians are said to have obtained a 
yellow dye from the trees, while the Pimas employed the inner bark for making 
breech clouts and skirts. 

Page 161. Salix humboldtiana. This and its synonyms should be placed in 
synonymy under Salix chilensis Mol. (Sagg. Chil. 169. 1782), the oldest name 
for the species.

1923. This was based on the same collections as Jatropha cercidiphylla Standl. 
(Contr. U. S. Nat. Herb. 23: 639. 1923). The latter name has priority of 
publication. The plant can scarcely be a species of Jatropha, but its reference 
to Astrocasia is equally doubtful, and it seems probable, as suggested by Johnston, 
that it may represent a distinct and new genus.

Shrub 1 meter high or so, very much branched above; joints bright green; 
tubercles prominent, elongate; areoles circular, brown-felted; spines on young 
branches 3 or more, long-acicular, up to 4 cm. long, brown, covered with a loose 
papery sheath; glochids numerous, whitish to brown; flowers yellow, 3 to 4 cm. 
long, including the ovary; ovary strongly tubercled; areoles subtended by small

Type collected by J. G. Ortega near La Cruz, Sinaloa, Mexico, in 1924 (no. 
5235; U. S. Nat. Herb. no. 1,209,382). 

This seems to be the same as the plant obtained by Rose near Alamos, 
Sonora, in 1910, which is referred to under O. kleiniae in the Cactaceae (1: 51). 
It differs from that species in its more spiny branches and yellow fiowers. 


Opuntia feroacantha Britt. & Rose, sp. nov. 

Bushy shrub with large joints and very formidable spines, glabrous through- 
out; joints oblong to obovate, 1.5 to 2.5 em. long, more or less cuneate at base; 
areoles rather few, 2 to 4 cm. apart, rather large, circular, brown-felted; glochids 
yellow, numerous; spines usually 1 or 2, sometimes a third or even a fourth one 
but these shorter, the longest one sometimes 8 cm. long or even longer, dull 
white or becoming brownish at base in age, very stout, often twisted; flowers 
small, rotate, about 4 cm. broad; petals yellow, 1.5 cm. long; filaments very short; 
stigma lobes about 7.
