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 Herbarium,”
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 of the Contributions from the United States
National Herbarium is made up of ten originally separate parts, com-
prising twenty-five papers in all.

The first part consists of a catalogue of the botanical library of
John Donnell Smith, presented by him in 1905, together with his
herbarium of more than 100,000 specimens, to the Smithsonian Insti-
tution. The library contains some 1,600 bound volumes, consisting
chiefly of works relative to systematic botany, and being especially rich
in works relating to Mexico and Central America. For the present,
the library is to remain in Baltimore, but Captain Smith has placed
his books freely at the disposal of botanists.

Not only have the books been selected with great care, but they are
all in conspicuously handsome bindings. It is doubtful if there is
any public or private botanical library of its size which can equal
it in value from either the scientific or the artistic point of view.
A simple but appropriate book plate has been designed and printed
and placed in each volume.

It is believed that the catalogue will be of interest and practical
value to many botanists. It is the work of Alice Cary Atwood, cat-
aloguer in the office of the botanist, Department of Agriculture.
The arrangement is by authors.

The second part comprises three short papers, the first two by
Mr. Henry Pittier. From 1887 to 1903 Mr. Pittier resided in Central
America, devoting a large part of his time to the study of its flora.
He made extensive collections and published various botanical papers.
Since coming to Washington, in 1903, Mr. Pittier has continued his
study of this flora, and in the two short papers herein offered he pre-
sents some of the results.

The third paper is a report by Mr. J. R. Johnston, of the Depart-
ment of Agriculture, upon a collection of plants obtained by Capt.
Wirt Robinson and Dr. M. W. Lyon, jr., in Venezuela. Mr. John-
ston was asked to determine these species because he had himself
collected in that country and was somewhat familiar with its flora.
The collection, though a small one, proves to contain five new species,
and this paper, like many others in the Contributions, emphasizes
the richness of the tropical American flora.

VI PREFACE.

The third part embodies the results of an. investigation by Prof.
A. S. Hitehcock, Systematic Agrostologist of the United States
Department of Agriculture, under the title, “Types of American
grasses: a study of the American species of grasses described by Lin-
neus, Gronovius, Sloane, Swartz, and Michaux.”

This paper is an important contribution to our knowledge of Ameri-
can grasses, from the nomenclatorial point of view. It is regarded as
practically a necessity in the critical systematic investigation of any
group of plants that the identity of the species described by earlier
authors be determined with certainty. Often this identification can
be made only by examining the type specimen, the original descrip-
tion being inconclusive. Under the American code of botanical
nomenclature,® which has been followed by the author of this paper,
“the nomenclatorial type of a species or subspecies is the specimen
to which the describer originally applied the name in publication.”

The procedure indicated by the American code, namely, to appeal
to the type specimen when the original description is insufficient. to
identify the species, has been much misunderstood by HKuropean
botanists. It has been taken to mean, in the case of the Linnean
herbarium, for example, that a specimen in that herbarium bearing
the same name as a species described by Linneus in his Species
Plantarum must be taken as the type of that species regardless of all
other considerations. In point of fact, the specimen preserved in
the herbarium of Linneus is often not the type specimen of the
species whose name it bears. Linnwus sometimes based a species
on the figure and description of an older author, but by mistake
placed in his herbarium a specimen belonging to a similar but distinet
species. He sometimes failed to preserve the specimen on which
one of his species was based, but later preserved some other specimen
incorrectly referred to the species. To consider such specimens
types would be quite contrary to the letter and the intent of the
American code.

An examination of the methods pursued by Professor Hitchcock
in locating and identifying the type specimens of American grasses
in European herbaria is earnestly commended to those botanists
who are not familiar with the method of types or who are opposed
to its application.

Opportunity was kindly given by various curators for the exami-
nation of specimens. Acknowledgment is made, however, to
B. Daydon Jackson, Carl A. M. Lindman, P. I. Lecomte, and A.B.
Rendle for special courtesies and assistance rendered by them in
facilitating the examination of colle Te tions in their charge.

PREFACE, VII

The fourth part consists of a paper by Mr. Henry Pittier on ‘‘The
Mexican and Central American Species of Sapium.”’

During the past few years much study has been bestowed upon
plants which furnish the rubber of commerce. This has shown that
many of these are unknown botanically, that those which have been
described have often been placed in wrong genera, and that the num-
ber of genera and species which may furnish rubber is likely to prove
much larger than has been supposed. It has been discovered not
only that several species of the genus Sapium produce a part of the
rubber of commerce, but that the genus is a very large one, and it
will doubtless be found that more of its species are capable of yield-
ing a satisfactory raw product.

Mr. Pittier’s paper on the species of Sapium of Mexico and Central
America is therefore, in view of the growing demand for rubber,
timely, and the contents are such as to make it an important contri-
bution to this subject. Most of the new species here proposed were
first studied by Prof. Karl Schumann, but his death occurred before
they had been published, or even manuscript upon them prepared.
Mr. Pittier has described the new species recognized by Professor
Schumann, together with two additional species distinguished by
himself, and has added, with appropriate notes, descriptions of two
already known.

Part 5 consists of a paper, also by Mr. Pittier, on ‘‘ New and Note-
worthy Plants of Colombia and Central America.’’ The plants
considered were selected from several collections which have recently
come into the possession of the United States National Museum.
These collections form a most valuable addition to the herbarium,
and their richness in new and rare species emphasizes the need of
still further field work in tropical America and the more extensive
study of the plants already collected.

A second paper by A. S. Hitchcock, entitled ‘Catalogue of the
Grasses of Cuba,” forms part 6 and is the result of an exhaustive
study of the material in the United States National Herbarium and
in the herbarium of the Estacién Central Agronémica de Cuba. It
was chiefly through the efforts of Mr. Carl F. Baker, who obtained
large collections in Cuba, that the specimens were made accessible
to Mr. Hitchcock. It is hoped that this paper will be followed by
similar ones upon other groups.

In part 7 Dr. J. N. Rose continues his “Studies of Mexican and
Central American Plants.’”’ This report varies little in style and
treatment from the five numbers which have already been published.
They all emphasize the botanical richness of the countries south of
the United States, and the importance of careful work by experienced
collectors.

VIII PREFACE.

Part 8 is occupied by a paper entitled “The Allionaceae of the
United States, with Notes on Mexican Species,” by Paul C. Standley,
now Assistant Curator in the Division of Plants, National Museum.
This was elaborated under the direction of Prof. E. O. Wooton, of
the Agricultural College of New Mexico, while Mr. Standley was
assistant professor in that institution. It embodies the results both
of field work and of a study of herbarium material from most of
the western herbaria, as well as the National Herbarium, and of all
the literature of the subject. Mr. Standley has aimed at a compre-
hensive and thorough treatment of the whole group, and has found
it necessary to establish several new genera and restore others not
recently accepted. The number of sheets studied belonging to the
National Herbarium was 1,068. Of the 50 new species here described
the types of 20 are in the National Herbarium, and others are repre-
sented here by duplicate types. The illustrations, except Plates
XXXIV and XXXV, are from drawings made by Mr. Standley
himself.

The ninth part contains eleven short papers upon new or note-
worthy plants. Of these the first ten, one by N. L. Britton and J. N.
Rose, the others by J. N. Rose, relate to North American plants,
chiefly Cactaceae and Crassulaceae from desert regions. The last
paper, by William R. Maxon, contains the description of a new fern
from China. This species was found in the Henry collection of
Chinese plants, a set of which is in the National Herbarium.

The final part is made up of miscellaneous papers, the first three
being continuations of studies published earlier in this series respec-
tively on the Cactaceae, Crassulaceae, and Apiaceae, prepared by
J. N. Rose, in collaboration with Dr. N. L. Britton, of the New York
Botanical Garden, and Prof. John M. Coulter, of the University of
Chicago. The last paper, by G. N. Collins, Assistant Botanist in the
Department of Agriculture, is an account of a remarkable develop-
ment in maize plants grown in a temperate climate from seed pro-
duced in the Tropics. It is a suggestive illustration of the effect of
environmental change.

Acting Curator.

PREFACE.

In January, 1905, Captain John Donnell Smith, of Baltimore,
Maryland, presented his herbarium and botanical library to the
Smithsonian Institution. The herbarium, consisting of more than
100,000 mounted specimens, became a part of the National Herba-
rium. The library contains some 1,600 bound volumes, consisting
chiefly of works relative to systematic botany, and being especially
rich in works relating to Mexico and Central America. For the
present, the library is to remain in Baltimore, but Captain Smith
has placed his books freely at the disposal of botanists.

Not only have the books been selected with great care, but they are
all in conspicuously handsome bindings. It is doubtful if there is
any public or private botanical library of its size which can equal
it in value from either the scientific or the artistic point of view.
A simple but appropriate book plate has been designed and printed
and placed in each volume.

An author catalogue of the library is presented herewith, which, it
is believed, will be of interest and practical value to many botanists.
The cataloguing has been done by Miss Alice Cary Atwood, cata-
loguer in the office of the Botanist, Department of Agriculture,

J. N. Roser,
Acting Curator.

PREFACE.

From 1887 to 1903 Mr. Henri Pittier resided in Central America,
devoting a large part of his time to the study of its flora. He made
extensive collections and published various botanical papers. Since
coming to Washington, in 1903, Mr. Pittier has continued his study
of this flora, and in the two short papers herein offered he presents
some of the results.

The third paper is a report by Mr. J. R. Johnston, of the Depart-
ment of Agriculture, upon a collection of plants obtained by Capt.
Wirt Robinson and Dr. M. W. Lyon, jr., in Venezuela. Mr. John-
ston was asked to determine these species because he had himself
collected in that-country and was somewhat familiar with its flora.
The collection, though a small one, proves to contain five new species,
and this paper, like many others in the Contributions, emphasizes
the richness of the tropical American flora.

THE LECYTHIDACEAE OF COSTA RICA.

by H. Pirrrer pe FABREGA.

On account probably of the difficulty of obtaining good specimens,
the Leevthidaceae of Costa Rica have been practically overlooked by
former collectors. The species do not appear to be numerous, and It
is likely that the present paper includes most of those to be found in
that country. as well as in the neighboring Republic of Nicaragua.
It should be mentioned, however, that one species of the genus Grias
has been found in Panama and may occur also within the limits of
Costa Riea. The four species described here belong to three of the
genera admitted by Niedenzu in his elaboration of the family for the
Pflanzenfamilien and a careful comparison of the material at hand
with Miers’s descriptions” has satisfied me beyond any doubt that
we have to do with hitherto unnoticed forms, except in the case of
Couroupita nicaraquarensis, discovered by Oersted some fifty vears
ago.

The species described here belong to the Lecythidoideae proper.
They are mostly large trees, with showy, dense foliage. The leaves
are alternate and exstipulate, entire except in one case, more or less
coriaceous. and with short petioles. The inflorescence is racemose.
The sepals and petals are 6 each. The stamens are united at the base
ina ring that is extended on one side in a helmet-like blade (andro-
phorum) inflexed above the ovary. The ovary is 2 to 6-celled. The
fruit isa capsule, or pyridinm, more or less coriaceous or thick-walled
and always polyspermous: its circumference generally shows 2 more
or less marked circular lines, the inferior of which corresponds to the
base of the sepals and has been called by Miers calycary zone, while
the upper is the line of dehiscence of the operculum and indicates the
junction of the floral disk with the vertex of the ovary. The space
between these two concentric Hnes is known as the énterzonary band.
The seeds differ in the three genera in their structure and mode of
attachment.

96 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

Of our three Costa Rican genera, Couroupita is an old and well-
defined one, established by Aublet,* while the two remaining have
undergone a considerable number of changes as to their systematic
position. Originally all the species divided now between Leeythis
and Eschweilera were included in the first, created by Loefling in
1758.” Von Martius was the first to show, although in a confused
way, the difference in the mode of suspension of the seeds, and to
propose the second genus, which appeared for the first time in De
Candolle’s Prodromus ¢ in 1828. Endlicher ¢ again brought together
all the species under Loefling’s genus, and this view was generally
accepted until Miers published his important memoir on the subject
in 1874. This botanist showed conclusively the value of certain
structural differences of the flower and the fruit for the rational
limitation of Lecythis, and from the excluded species he formed his
three genera Eschweilera, Chytroma, and Jugastrum, which were
subsequently found to differ from each other to a much less extent
than they do together from Lecythis, and which have in consequence
been reduced by Niedenzu to mere sections of one single genus, for

“which the old name Eschweilera, given by von Martius, has been
retained. Of the two Costa Rican species of that genus, one cer-
tainly belongs to the section Eueschweilera, while I place the second
with doubt, until the flowers have been investigated, in the section
Chytroma.

the flora of South America, this is the only species that goes beyond the Isthmus
of Panama. It is one of the most Conspicuous trees in the forests between
Granada and Tortuga (Nicaragua), where it attracts the attention of the
passer-by by its lofty trunk, regular round crown, and large, globose fruits,
hanging in close clusters. I found mature fruits in February. These are called
by the natives * zapotes del mico,” on account of their likeness to the true za-
potes (Lucuma) and the readiness with which they are eaten by the monkeys.
A closely allied species, C. guianensis, is known in Guiana under the name of
cannonball tree.” 4

As will be seen from the present paper, our knowledge of the species of the
family north of Panama has somewhat improved since Oersted’s time, although
much remains to be done. Complete specimens of Couroupita nicaraguarensis
has never to my knowledge been collected, and I am aware of the presence of
that tree in Costa Rica only because it came under my observation in 1891 at
Salinas Bay (where it is also known as zapote de mico) and in Nicoya in 1903.
The round fruits, slightly swollen along the calycinal band, were about 10 cm.
in diameter and filled with a nauseous pulp surrounding numerous seeds.

The flowers of the nearly related C. guiaqnensis, which is the type of the genus,
are about 10 cm. in diameter, with petals 4.5 ecm, long and 3.5 cm. broad (Plate
V). Its very much elongated racemes grow directly from the trunk and main
limbs, as shown in Plate V (as well as Plate IV) taken at the Castleton Guar-
dens in Jamaica by Mr. G. N. Collins. I do not remember having noticed any
such arrangement in the Costa Rican zapote de mico, and the flowers escaped
my attention.

Plate V is natural size.

Meirs 8 inclines to the belief that this species is identical with C. odoratissima
Seemann. The above description settles the question in the negative. The
leaves of C. nicaraguensis are obtuse and neither cuneate at the base nor
abruptly acuminate at tip; the flower is 7.5 cm. in diameter, while it varies
from 4 to 5 em. in Seemann’s plant; further, the anthers in our species are ses-
sile on the appendages and not borne on capillary filaments, as is the case in the
other one.

The tree bears and is easily reproduced by seeds. Six of these, planted in
the garden of the observatory at San José, all germinated after having been
from twenty-eight to thirty-six days in the ground. For some reason they had
to be removed with the exception of one, which had reached a height of about
380 cm. above the ground in three months. There is little doubt that the
tree could be cultivated with no great difficulty in its native home, in the
war, humid plains of San Carlos, Sarapiqui, and Santa Clara, and in other
tropical countries of similar climatic conditions. The output of the nuts would
thus be increased, and these might become a valuable addition to the food
products of our markets.

the herbarium of the Instituto fisieco-geogrifico de Costa Rica, arriving at the
conclusion that it belonged to an undescribed genus, About the time Mr. Don-
nell Smith published his new species I was greatly surprised to receive from
Doctor Renson a fruiting specimen of the Salvadorean plant, which showed
at a glance Captain Donnell Smith's mistake, and also the close affinity of his

TONDUZIA STENOPHYLLA ‘DONNELL SMITH) PITTIER.

A COLLECTION OF PLANTS FROM THE VICINITY OF
LA GUAIRA, VENEZUELA.

By J. It. JomNsron.

INTRODUCTORY NOTES.

In 1900 Capt. Wirt Robinson, of the United States Army, and Dr.
M. W. Lyon, jr., of the United States National Museum, spent six
weeks in the vicinity of La Guaira collecting for the most part speci-
mens of animals. Incidentally they were able to gather together
about 60 plants, which were sent to the United States National Her-
barium, and most of which have recently been turned over to me for
identification.

The plants in the following list were all collected near La Guaira,
Macuto, and San Julian. Macuto is about 5 kilometers to the east of
La Guaira on the coast, and San Julian is about 12 kilometers to the
east of La Guaira and nearly 1§ kilometers from the shore. For a
description of the topography, temperature, and rainfall of this
region one should refer to “An annotated list of mammals collected
in the vicinity of La Guaira, Venezuela,” by Robinson and Lyon, in
the Proceedings of the National Museum."

It is sufficient to say in this connection that the shore rises abruptly
to an altitude of over 2,500.meters immediately above La Guaira, and
that the exposed hills are barren or covered with a dry shrubbery,
the low valleys with palms and other trees, and the high gorges with
a great luxuriance of tropical vegetation. The very narrow littoral
plain is clothed with a typical desert vegetation of cacti, crotons,
lantanas, ete.

In addition to the list of Robinson and Lyon’s plants it has
seemed well worth while to include under each species notes of
its further occurrence in Venezuela as determined from other collec-
tions. It should be noted that the plants of Fendler, of Birschel, and
of Rusby and Squires here cited as occurring in Venezuela have not
before been published upon, at least so far as I can ascertain. The
notes made here are obtained from reference to the plants at the
United States National Herbarium and at the Gray Herbarium of
Harvard University.

The identification of the plants shows five species which are new
to science. As far as can be ascertained, nine of the remaining species
have never been recorded from Venezuela, and three have never be-
fore been collected there, these being Phoradendron trinervinum,
Corchorus pilobolus, and Marsdenia maculata. The remainder of
the nine are in the collections that have not been reported upon.

PREFACE,

The accompanying paper, by Prof. A. S. Hitchcock, Systematic
Agrostologist of the United States Department of Agriculture,
entitled ‘‘Types of American grasses: a study of the American
species of grasses described by Linnwus, Gronovius, Sloane, Swartz,
and Michaux,” is an important contribution to our knowledge of
American grasses.

It is regarded as of fundamental importance in the critical sys-
tematic investigation of any group of plants that the identity of the
species described by earlier authors be determined with certainty.
Often this identification can be made only by examining the type
specimen, the original description being inconclusive. Under the
American code of botanical nomenclature, which has been followed
by the author of this paper, ‘‘the nomenclatorial type of a species or
subspecies is the specimen to which the deseriber originally applied
the name in publication.”

The procedure indicated by the American code, namely, to appeal
to the type specimen when the original description is insufficient to
identify the species, has been much misunderstood by European
botanists. It has been taken to mean, in the case of the Linnean
herbarium, for example, that a specimen in that herbarium bearing
the same name as a species described by Linneus in his Species
Plantarum must be taken as the type of that species regardless of all
other considerations. In point of fact, the specimen preserved in
the herbarium of Linnwus is often not the type specimen of the
species whose name it bears. Linneus sometimes based a species
on the figure and description of an older author, but by mistake
placed in his herbarium a specimen belonging to a similar but distinet
species. Ile sometimes failed to preserve the specimen on which
one of his species was based, but later preserved some other specimen
incorrectly referred to the species. To consider such specimens
types would be quite contrary to the letter and the intent of the
American code.

TYPES OF AMERICAN GRASSES: A STUDY OF THE AMER-
ICAN SPECIES OF GRASSES DESCRIBED BY LINNZEUS,
tRONOVIUS, SLOANE, SWARTZ, AND MICHAUX,

By A. 8. Hrrencock.

INTRODUCTION.

During the spring of 1907 I had the opportunity of examining
many types of American species of grasses deposited in European
herbaria. In the present paper I have considered the species of
grasses described by Linneus, Gronovius, Sloane, Swartz, and
Michaux, the first only so far as they are based upon American ma-
terial. No attempt is made to determine the types of Old World
species.

Since the older authors did not indicate their types, these must be
determined from the records which have been preserved. The type
specimen is the specimen or one of the specimens from which the
author drew up the description. The specimen often supplements
or interprets the description. If the author mentions in his original
description a definite specimen, if this specimen has been preserved
and its identity certified by the data upon the label and by the name
of the species added by the author, it is clear that this specimen is
the type. However, it often happens that the evidence is less com-
plete. An author may have based his description upon more than
one plant (Panicum pubescens Lam., see page 147); the supposed type
may not agree perfectly with the description (Andropogon ischaemum
L., page 126); the author may have written the name upon more than
one sheet or upon a sheet which is not mentioned in the description
(Panicum latifolium 1.., page 118); the locality or other data on the
label of the type specimen may not agree with that published
(Zizania fluitans Michx., page 156); the type specimen may have been
sent to another herbarium (Panicum dichotomiflorum Michx., page
147); the type specimen may be accompanied by a specimen of a dif-
ferent species upon the same sheet (Panicum dichotomum L., page 117) ;
or the type specimen may bear a name on the label which is different
from the one published (Chloris monostachya Michx., page 152); or

there may be several specimens from which the type must be selected
by comparison with the description (Panicum barbulatum Michx.,
page 148). These and other difficulties complicate the study and
make it necessary to examine carefully all the evidence. This evi-
dence not infrequently shows that a species has been misunderstood.
The original description may be insuflicient to identify the species,
but the identity can be established by the type specimen (Panicum
nitidum Lam., page 148). Tradition may have attached a name to
one species, while the description and the type specimen show that
the name belongs to another species (Cenchrus tribuloides L., page 127;
Agrostis aspera Michx., page 150).

In the following account I have considered each case upon its
merits and have presented the evidence upon which I have based
my decision. It will be seen that usually the apparent difficulties
disappear and we are able to determine the specimen the author
had chiefly in mind when he wrote the description. The earlier
authors, especially Linneus, frequently cited descriptions or plates
which they considered as referring to the same plant they were describ-
ing. Linneus even based his binomial upon the description or plate
of another author. If an author quotes the diagnosis of a species
described by another author and gives a name to this, but has no
description of his own, the type of the older author becomes the
type of the later (Panicum capillare, L., page 118). Linneus often
gave binomial names to species described by others. But if Linnzus
wrote a description and there has been preserved a specimen which
the evidence shows must have been seen by him when he drew up
the description, this specimen is the type, and not the specimen
which is the basis of the synonym (Panicum latifolium L., page 118;
Paspalum paniculatum L., page 116). The danger of placing too much
weight upon cited synonyms as evidence is shown by the fact that
Linneus sometimes cited a given Sloane plate under different species
in different works or even in the same work (Panicum sanguinale
L., page 117); or the synonyms may be quite different from the species
under which they are cited (Andropogon nutans L., page 125).

Fortunately the grasses left us by the older authors, though often
fragmentary, are in a satisfactory state of preservation, and it is
usually possible to determine their identity with certainty.

THE AMERICAN GRASSES DESCRIBED BY LINNZAUS.

The herbarium of Linneus, preserved at the rooms of the Linnean
Society of London, Burlington House, Piccadilly, contains most of
his types. In the following article I have considered only those
species based wholly or in part upon American material, nearly all
of which was furnished by Kalm, Gronovius, Sloane, or Browne. In
the case of Old World species the specimens preserved by Linneus

may not be type specimens, as he often applied a binomial to a species
already well known, but his American species may usually be traced
back to definite type specimens. The specimens from Kalm are
marked by Linneus with a small “Kk.” These specimens are credited
to Canada by Linneus, but Kalm traveled as far south as Pennsyl-
vania and New Jersey. The specimens from Patrick Browne in
Jamaica are marked “Br.’? The Gronovius specimens were collected
by Clayton‘and are described in Gronovius’s Flora Virginica. When
Linneeus quotes Gronovius’s diagnosis, Gronovius’s species is the
type and is represented by a specimen in the British Museum. Often
Linneus has a specimen in his own herbarium received from Grono-
vius which he describes, citing Gronovius as a synonym. In such
cases the Linnwan specimen is the type. Linneus often cites Sloane's
plates, but only occasionally quotes his diagnoses. Sloane's speci-
men is the type only when Linneus quotes Sloane’s diagnosis and
has no description of his own. In all cases it must be evident that
Linneus drew up his description wholly or in part from the preserved
specimen, which then becomes the type.

Cinna arundinacea L. Sp. Pl. 5. 1753.

This is the species as described in our manuals. The spikelets are nearly 5 mm.
long. Linnzeus states in his description that Kalm obtained the seed in Canada, The
sheet is marked “H U.” 4

Phalaris oryzoides L. Sp. Pl. 55. 1753.

There are two sheets, both bearing the name in the handwriting of Linnaeus. One
of these has a small label pasted on one corner of the sheet, ‘‘Gramen miliaceum Vol. 1,
pag. 350. n. 1.” This, which is clearly the type, is Homalocenchrus oryzoides (L.)
Poll. Munro states that this specimen is from Gronovius. The type locality of the
species, as given by Linneeus, is Virginia. The second sheet, on the other hand,
marked “Br” and therefore from Jamaica, is HIomalocenchrus herandrus (Sw.) Kuntze.
Sloane’s plate 71, figure 1, cited later by Linn:eus? is an Eragrostis.

Panicum dissectum L. Sp. Pl. 57. 1753.

Upon this sheet Linneus wrote “‘dimidiatum,’’ which is crossed out, and “‘dissec-
tum; also‘ K.’ The plant is what has been called Paspalum membranaceum Walt.
Spikes 4, with others hidden in the sheath; spikelets 2 mm. long.

In determining the type of Panicum dissectum L. several points must be taken into
consideration. Linnzeus describes the plant as follows, ‘Panicum spiculis alternis;
rachi lineari membranacea extrorsum imbricato-florifera.”’ This applies to the her-
barium specimen. The first synonym cited is “ Dactylis spicis alternis numerosis
patulis, calycibus unifloris. Roy. lugdb. 56.7" The character * spicis numerosis ”
not apply to the Linnean specimen. The second synonym, Plukenet, “Mant. 94. t.
350. f. 2” (irom America), can scarcely be the same as the specimen of Linnzeus, for
the blades of the figure are long and gradually narrowed to a point. The third syno-
nym is a citation from Sloane, Hist. Jam. 1: 112. pl. 69. f. 2. This is the plant now
called Paspalum virgatum, as shown by the plate and by the specimen preserved in
the British Museum. The same plate is cited by Linnzeus under Andropogon fascicu-

does

latum.« The habitat of Panicum dissectum is given by Linnwus as ‘in Indiis.”’ We
obtain more hght by noting how Linneus disposed of the species in subsequent works.
The next reference is in the tenth edition of his Systema Naturae> where the genus
Paspalum is established. The first species is dimidiatum, ‘‘P. spicis subsolitariis,
pedunculo communo membranaceo. Panicum dissectum, Sp. Pl. 57. n. 6.’ Although
he bases the new name upon Panicum dissectum, he changes the specific name to
dimidiatum. As his species of Panicun. No. 7 in the first edition was called P. dimi-
diatum, and there is no doubt that this is what we now call Stenotaphrum dimidiatum,
Linnieus apparently became confused, or inadvertently transferred the wrong name.
The real Panicum dimidiatum is omitted in the tenth edition of the Systema, but
reappears in the second edition of the Species Plantarum. That Linnweus made a
slip of the pen in his citation of 1759 is shown by the fact that in the second edition of
his Species Plantarum he restores the name dissectum and we have Paspalum dissectum
based on Panicum dissectum of the first edition. Plukenet’s figure is still cited, but
the other synonyms are omitted. Sloane’s plant was taken out and given the name
Paspalum virgatum 1..¢ and the same disposition was made of it in the second edition
of the Species Plantarum. In the latter work Linnzeus changes the habitat of Pas-
palum dissectum to ‘‘America calidiore,”’ and adds a further description which cer-
tainly applies to the specimen from Kalm rather than to any of the others under
consideration, ‘‘Gramen prostratum foliosum vaginis fere spathaceis. Spicae paucae
rachi membranacea dilatata ad latitudinem spicae ipsius distichae & secundae. Flores
orbiculati.”’

From the above it seems clear that Linnzeus had Kalm’s plant before him when he
wrote his description of 1753, but that he erred in his synonyms. We must not place
too much weight upon the localities, Indies and America calidiore, for at that time
there was little knowledge concerning the distribution of American plants. Paspalum
scrobiculatum 1..¢ from *‘ India orientali” has been considered by some a synonym
of P. disseetum (as Hooker in Fl. Br. Ind. 7: 11. 1896), but Iam unable to find any
evidence to support this disposition.

It seems proper that we should regard Kalm’s specimen in Linnzeus’s herbarium
as the type of Panicum dissectum L. and that this name should be taken up for the plant
we have been calling Paspalum membranaceum Walt., which becomes Paspalum
dssectum (.) L.

Paspalum virgatum L. Syst. Nat. ed: 10. 2: 855. 1759.

The specimen is from ‘ Br” and is the same as the Sloane plant referred to unde
the preceding species. The plant from Browne is the type, for, although Linnzeus
cites Sloane’s plate 69, figure 2 under this species, / he does not quote Sloane’s diagnosis
but gives one of his own.

Paspalum paniculatum L. Syst. Nat. ed. 10. 2: 855. 1759.

The plant is what has been going under that name in the floras of tropical America.
Linneus here cites Sloane’s plate, but uses his own diagnosis, which is quite different
from that of Sloane. His description ‘“P. paniculae spicis inferioribus subgeneris
basi villosis,’’ certéinly apples to his own plant received from Browne rather than
to the Sloane plant or plate. I can not agree with Mr. Nash, who makes Sloane’s
plant (which is Panicum fasctculatum Sw.) the type of this species, and hence calls
it Panicum paniculatum (L.) Nash.g This combination could not be used in any case

AMERICAN GRASSES DESCRIBED BY LINNAEUS. 117

Paspalum distichum I. Syst. Nat. ed. 10. 2: 855, 1759.

There is no indication on the sheet as to the source of the specimen, though Munro
states that itis from Browne. The specimen belongs to this species as generally under-
stood. Spikes 2 or 3; spikelets 3 mim, long, acute, pubescent on the convex side. —

Panicum glaucum IL. Sp. Pl. 57. 1753.

The type and form / are from the Old World but » is based on ‘Panicum spica
simplici, aristis aggregatis flosculo subjectis. Gron. virg. 184.7? This last form is
represented by Clayton no, 579 and is the ordinary form of Chaetochloa glauca (1.)
Scribn. .

Panicum crusgalli L. Sp. Pl. 56. 1753.

One sheet marked ‘K” is the ordinary small form of this species. This specimen
must be considered the type, since it agrees with the description and is the only one
to which Linnzeus has attached the name. Pinned to this are two other sheets both
from Gronovius. One is the large-panicled, short-awned form, with stout erect culms
and is the same as the plant in the Gronovius herbarium, cited in Gron. Fl. Virg. as
Clayton no, 591, and bears the label, “591 panicum arvense paniculis fuscis densiori-
bus glumis hispidis aristis brevioribus,’? which is quoted by Gronovius. On the
second sheet is the large-panicled, long-awned form with hispid sheaths, now called
Echinochloa walteri (Pursh) Nash. It bears the label, 579 pl. 2 Panicum arundina-
ceum spica ampla densa hispida purpurea longis aristatis Clayt.,’’ which is mentioned
by Gronovius,@ who also quotes the Bauhin citation given by Linnzeus under 6. This
is, therefore, the specimen upon which the locality ‘‘ Virginiae cultis” is based and
represents Linnzeus’s idea of Panteum erusgalli fp.

Panicum sanguinale L. Sp. Pl. 57. 1753.

The specimen upon which Linneeus has written the name is marked “HU” and is
the ordinary form of this species, Syntherisma sanguinalis (L.) Dulac, as is another
sheet pinned to this with a citation from Sloane. Linnzeus cites “Gron. virg. 154,”’ in
his description. The plant, Clayton no. 457, could not be found at the British Museum,
but there is no doubt that Gronovius was describing our ordinary crab-grass— a name
which he uses. Linnzeus also cites “Sloan. Hist. 1, p. 118. t. 70. f. 2° a synonym
which, however, does not affect the identity of the type. In Sloane’s herbarium two
specimens are covered by this citation. One is Leptochloa virgata (L.) Beauy., the
other L. mucronata (Michx.) Kunth, but the plate is taken from the former. This
plate is cited under Cynosurus virgatus in the Systema Naturae,? and under both
Cynosurus virgatus (page 106) and Panicum sanguinale (page 85) in the second edition
of the Species Plantarum (1762),

Panicum filiforme L. Sp. Pl. 97. 1753.

The sheet taken as the type is marked “ K’’ and is the ordinary form, Syntherisma
filiformis (L.) Nash. A second sheet, also marked “1K”? has this and a specimen of
Muhlenbergia schreberi Gmel, A third sheet marked “ HU” is Syntherisma sanguinalis

(L.) Dulac.

Panicum dichotomum L. Sp. Pl. 58. 1753.

Linnwus’s specimen, marked “K7’, is Panicum microcarpon Muhl. (2?. barbulatum
of our manuals, not Michaux). Nodes barbed, spikelets 1.5 mm. long. Munro states
that this is “the plant described by A, Gray as dichotomum.”’ The latter, however,
has smooth nodes and spikelets 2mm, long. It should be noted that since Linnieus
gives no description of his own but quotes that of Gronovius the plant of Gronovius
becomes the type. Gronovius’s specimen (Clayton no, 458) consists of two plants,
one of which is the P. dichotomum of our manuals and the other P. odigosanthes Schultes.
The description applies better to the former, which should therefore be taken as the
type. This retains the name in the traditional sense.

118 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

Panicum clandestinum L. Sp. Pl. 58. 1753.

The type, from “ K’’, is the autumnal state of this species as commonly understood,
Linnzeus also cites Sloane, Hist. 1: 120. pl. 80, which is [ackelochloa granularis (1.)
Kuntze ( Manisuris granularis Sw.), but the’ description of Linneeus does not apply to
this.

Panicum capillare L. Sp. Pl. 58. 753.

The specimen is from “HoU.”’ Since Linneeus gives no description of his own,
but bases the name on ‘‘Gron, virg. 13,”’ the type is Clayton no. 454. This, which is the
same as the Linnwan plant, is the broad-leaved form with ample panicle, as described
in Britton’s Manual. Linnzeus’s citation® of Sloane® is Panicum trichoides Sw-
A specimen in the Stockholm herbarium marked “K’’ by Linnzeus is P?. philadelphi-
cum Bernh,

Panicum latifolium L. Sp. Pl. 58. 1753.

There are two plants from “K’? upon the sheet on which Linnzeus has written the
name. The left-hand plant is Panicum macrocarpon LeConte; the right-hand
plant is Panicum clandestinum 1, both in the vernal state. Pinned to this is a sheet
of Panicum divaricatum I., but Linnzeus has not written the name upon this. There
is also a third sheet upon which Linneeus has written the name and “Br.’’ This is
Panicum oryzoides Sw., but itshould be excluded from consideration, as Linnzeus appears
to have received Browne’s plants after he prepared his Species Plantarum; at least he
does not cite Browne’s specimens in the first edition, Linnzeus ¢ cites Sloane, Hist.
Jam. 1: 114. pl. 77. f. 3, the species referred to being now called Panicum sloanei
Griseb. It is the broad-leaved form with large panicle as distinguished from P.
divaricatum LL. Linnwus@ gives a rather extended description, which applies to the
first sheet mentioned above and not to the others. It would apply, I think, to
either of the two plants upon this sheet, but rather better to the left-hand plant
(P. macrocarpon LeConte). It has wider blades and the hairs around the base of the
blades are as described: “Folia latitudine Commelinae ad fauces amplexicaulia;
extus collo circum fauces villoso, etiam basi foliorum margine pilosa.”’ Further-
more, he has already described Panicum clandestinum. The leit-hand plant is there-
fore taken as the type and the name Panicum latifolium L. will stand for what we
have been calling Paniewm macrocarpon LeConte, Some botanists have applied
the name P, latifolium to the Sloane plant, but Sloane’s polynomial is a synonym
incorrectly cited. It should be noted that Sloane’s polynomial is the second syno-
nym given by Linnzus, the first being from Morison’s History, which probably is P.
boseii, but certainly is not the Sloane species. The plant described as Panicum lati-
folium by Gray and other early American botanists differs from P, macrocarpon
LeConte in having bearded nodes and larger spikelets. This is described in Britton’s
Manual as P. porterianum Nash, but an earlier name is 2. boseii Poir., the type of
which is in the herbarium at Florence.

Panicum virgatum L. Sp. Pl. 59. 1753.

The type sheet bears the number 578 and Gronovius’s polynomial which accompa-
nies this Clayton number in the Flora Virginica.e It is the species deseribed in our
manuals as Panicum virgatum. Pinned to this is a sheet of the same species bearing
the number 606 and Gronovius’s polynonual corresponding to this number of Clayton
in his Flora, Linnzeus has written the name upon the first sheet only.

AMERICAN GRASSES DESCRIBED BY LINNEZUS. 119

Panicum hirtellum L. Syst. Nat. ed. 10. 2: 870. 1759.

The type, from ‘Br,’ is Oplismenus hirtellus (L.) Roem. & Schult., and is more
fully described in Amoen. Acad. 5: 391, 1759. The axes of the spikes are hispid, as
also the spikelets, but not theaxisof the inflorescence. Theawns are about | cm. long.

Panicum colonum I. Syst. Nat. ed. 10, 2: 870. 1759,

There are two sheets in the herbarium ranked by Linneus, one being from ‘Br.
Both are P. colonum as generally understood, though Munro states that one is P.
crusgalli, 1 should consider the specimen from Browne to be the type, as it answers
better to Linnzeus’s description, Linnzeus cites Sloane’s plate 64, figure 2, but does
not use his diagnosis, hence Sloane’s plant is not the type.

ce)

Panicum reptans I.. Syst. Nat. ed. 10. 2: 870. 1759,
This name should replace P. grossarium, as indicated below under that title.

Panicum grossarium L. Syst. Nat. ed. 10. 2: 871. 1759.

Nospecimen or locality is cited here by Linnweus but the plant is more fully described,
later, in his list of Jamaica plants.¢ The specimen in the herbarium is from ‘‘ Br.”
The word ‘“‘reptans” was written on the sheet and then crossed out. Panicum reptans
L. Syst. Nat. ed. 10, 2: 870, 1759, has been regarded as of uncertain identity. The
description applies to this specimen and, as this name is omitted in all the later works
of Linnzeus, it is quite probable that he described the same plant twice. The descrip-
tion of Panicum replans, placed between P. hirtellum and P. sanguinale, is as follows:
“P. panicula racemis simplicibus alternis secundis, flosculis geminis muticis: pilis
rarioribus involucratis.’” On the next page is the character of Panicum grossarium
(between 2. miliaceum and P. latifolium); ‘+P. panicula ramis simplicibus, floribus
geminis: pedicello altero brevissimo; altero longitudine floris.’’ The specimen is
not what has been considered Panicum grossarium by most authors but is Panicum
prostratum Lam. Hl.Gen. 1: 171. 1791. TI propose then to take up the name Panicum
reptans L. tor the grass which has been known as 7. prostratum Lam. Linnzeus’s de-
scription quoted above applies perfectly, even to the occasional long hairs on the
rachis. I am assuming that Richter is correct in placing the date of publication of
the tenth edition of the Systema in May, 1759, and the dissertation entitled ‘“ Pugillus
Jamaicensium plantarum” in December, 1759. In the latter work P. grossarium is
described, but P. reptans isnot mentioned.

The plant which has been called Panicum grossarium and for which a different
name must be taken up is Panicum “een Trin. Gram, Pan. 146. 1826,

Panicum divaricatum L. Syst. Nat. ed. 10. 2: 871. 1759
The specimen is from “Br.’’ It is the sina leaved clambering form which is also
found in southern Florida.

Milium punctatum L. Syst. Nat. ed. 10. 2: 872. 1759.

120 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

Agrostis indica L. Sp. Pl. 65. 1753.

The type specimen from “ Br,” is Sporobolus indicus (.) R. Br. Linnzeus@ cites as
a synonym, Sloane, Hist. Jam. 1: 115. pl. 73. f. 1. This also is Sporobolus indicus,
Linneus cites the same plate under Poa ciliaris.

Agrostis radiata L. Syst. Nat. ed. 10. 2: 872. 1759.

The specimen in the Linnean herbarium from “ Br?’ is Chloris radiata (L.) Sw. as
described in Grisebach’s Flora. Chloris radiata (1.) Sw. Prod. 26. 1788, is based on
Agrostis radiata LL. Swartz’s specimen is also this species. After his own description
in the Systema Linnzeus cites Sloane’s plate 68, figure 3, but does not use his diagnosis,
hence the Linnean plant is the type. Sloane's plant is Chloris eleusinoides Griseb.

Agrostis cruciata L.. Syst. Nat. ed. 10. 2: 872. 1759.

The specimen is from “ Br.’? Linnzeus cites Sloane’s plate 69, figure 1 after his own
description, but does not use his diagnosis, hence Browne’s plant in the Linnean her-
barium is the type. This and Sloane’s plant are Chloris cruciata (L.) Sw., as generally
understood.

Aira spicata L. Sp. Pl. 64. 1753.

All the species of Aira of Linnzeus are based upen Old World material. Linneeus
inadvertently gave the specific name spicata to two species of Aira in the same publi-
cation, The first is on page 63. He discovered this error and in the errata, volume 2,
changed the name of the first to indica. In the tenth edition of the Systema Naturae
he described the first species under the name 1. ¢ndica and the second he changed to
A. subspicata, thus eliminating the name spicata altogether. In the Species Plan-
tarum, ed, 2, 1762, the name spicata is retained for the second, probably inadvertently.
The two specimens in the herbarium show evidence of these changes. The first sheet,
which is Panicum indicum, shows the word Aira with a line drawn through, Panicum
written in front, and the final “a’’ of the specific name changed to “wm. The
second sheet, which is Trisetium subspicatum (L.) Beauv., shows that ‘sib’? has been
later prefixed to “spicata.”’ The specimen of this is pubescent like Avena mollis
Michx. ( Trisetuum molle (Michx.) Kunth.) Some authors have restricted the Linnsean
name to the glabrous form and used Michaux’s name for the pubescent form, either as
a species or a subspecies. It the two forms are considered distinct, the glabrous form
must receive a different name. .

As Linneeus corrected the name of the first Aira spicata to Aira indica in his list. of
errata, the latter name is valid for that species. The second Aira spicata is also valid
and the name of the species is Trisetum spicatum (L.) Richter, Plant. Europ. 1: 59,
1890 (7. subspicatum (L.) Beauy.; 7. molle (Michx.) Kunth.)

Aira aquatica L. Sp. Pl. 64. 1753 (Catabrosa aquatica (..) Beauv.), A. caespitosa L,
loc. cit. (Deschampsia caespitosa (.) Beauv.), and A. fleruosa L. op. cit. 65 (Des-
champsia fleruosa (L.) Trin.) appear to be identical with our North American forms.

Poa flava L. Sp. Pl. 68. 1753.

lescens Michx. (a herbarium name for this species) to Tricuspis caroliniana. But on
account of Tricuspis Pers. 1807, Roemer and Schultes changed the name of the genus
to Tridens, citing Beauvois’s figure. The type species is Tridens quinguifida (Poa

Poa capillaris L. Sp. Pl. 68. 1753.

The type specimen, from ‘K,’’ is Hragrostis capillaris (L.) Nees. The Gronovius
specimen incorrectly cited by Linnzeus (Clayton no, 580) is Eragrostis pectinacea
(Michx.) Steud. .

Poa ciliaris L. Svst. Nat. ed. 10. 2: 875. 1759.
The type specimen, from “Br,” is Eragrostis ciliaris (L.) Link. Linneeus@ cites
Sloane’s plate of Sporobolus indicus under this.

Briza eragrostis [.. Sp. Pl. 70.

The type specimen, from MK “is Eragrostis megastachya (Koel.) Link. The
Gronovius reference (Clayton no. 582) is the same. Both are the more compact-
panicled form. Linngeus’s specimen of Poa eragrostis L. Sp. Pl. 68. 1753, from Europe
is the form with more open panicles, but has the same large spikelets. The European
botanists (e. g. Ascherson and Graebner, Syn. Mitteleurop. Fl. 2: 372.1900.) consider
Poa eragrostis L. to be the allied species (Eragrostis minor Host) with smaller, gland-
less spikelets, and quite open panicle. Though the Linngean specimen is Eragrostis
megastachya, yet the name Poa eragrostis may perhaps be considered as applicable to a
traditional species rather than to the specimen in his herbarium, This is a question
which European botanists will doubtless be prepared to decide, It seems to me,
however, that the description applies better to his specimen (‘‘spiculis serratis decem-
floris”) than to Eragrostis minor,

Uniola paniculata L. Sp. Pl. 71. 1753."

The type specimen is marked ‘ Uniola 1,’’ that is, the first Uniola described in the
Species Plantarum. It belongs to this species as generally understood. Linnzeus
cites Gronovius, ‘‘ Uniolacalycibus polyphyllis.”” In the first edition of Gronovius
this citation is based upon a reference to Hortus Cliffortianus and not upon a Clayton
plant. In the second edition a Clayton plant, no, 909, is mentioned, but this number
could not be found in the British Museum. There is no doubt, however, as to the
identity of the plant; it is the same as that of Linngeus. Gronovius refers to a figure
of Plukenet and gives the common name ‘‘sea-side oat.’’

Uniola spicata L. Sp. Pl. 71. 1753.

The type specimen, from “ K,”’ is Distichlis spicata (L.) Greene. Aiter his diagnosis
Linneeus cites Clayton no. 507, but this is Sporobolus virginieus (L.) Kunth, Linngeus
had already cited this number of Clayton under Agrostis virginica,

1753.

Dactylis cynosuroides L. Sp. Pl. 71.

The Linngean specimen, which is the type, is from Gronovius and is marked with
the number 577 and accompanied by Gronovius’s diagnosis. Gronovius’s plant cited
by Linneeus (Clayton no, 577) is the same, namely, Spartina polystachya (Michx.) Ell.
and should be called S. cynosuroides (L.) Willd. ¢

Linnzus subjoins a variety £8 based on a Gronovian citation. The corresponding
plant, Clayton no. 583, is Spartina glabra Muhl.

A second sheet pinned to the Linnean plant mentioned above (no. 577) is marked
by Linneus ‘1,’ that is the first species of Spartina. There is also a label attached
which says “ Phalaroides spicis inearibus subternis terminalibus secundis adpressis. ”?
This citation is from Loefling.@ The plant appears to be Spartina stricta of Europe,
and is probably the basis of the European habitat. (Linnzeus gives as habitat, © Vir-
ginia, Canada, Lusitania.’’) There is no evidence of his having seen a plant from
Canada. Linnzeus’s diagnosis ‘‘spicis sparsis secundis scabris numerosis’? applies to
the first Gronovian plant cited rather than to cither of the others.

122 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

Cynosurus virgatus L. Syst. Nat. ed. 10. 2: 876. 1759.

The type specimen, from “Br,’’ is Leptochloa virgata (L.) Beauv. After his own
description Lifnzeus cites Sloane’s plate 70, figure 2, but does not use his diagnosis,
hence Sloane’s plant, which is also Leptochloa virgata, is not the type. Linnzeus cites
the same plate of Sloane under Panicum sanguinale.¢

Bromus purgans L. Sp. Pl. 76. 1753.

One sheet is marked ‘3 purgans H U.’’ The specimen has rather sparsely retrorse-
pubescent, overlapping sheaths and evenly pubescent spikelets. This is B. latiglimis
(Scribn.) Hitche.2 (Bromus altissimus Pursh, not Gilib.). A second sheet is marked
“K 4.’’ In this specimen the sheaths are not overlapping, but the spikelets are
pubescent all over like the first. This is B. purgans as ordinarily understood and as
described in Shear’s Monograph of Bromus.¢ A third sheet is marked “H U 4°’ and
is like the first sheet. It will be observed that there is considerable confusion here.
Bromus no. 3, as described in the Species Plantarum, is called purgans, and no. 4 is
called cilatus. Both are said to come from Canada, collected by Kalm, the latter
(ciliatus) being from seed. But none of the specimens is B. ciliatus as we understand
the species@ nor corresponds to the description given by Linnzeus, which is unusually
ample. In his description he states ‘‘ petalorum marginibus (non dorso) valde pilosis,”
while in the specimens the lemmas are pubescent all over, as described for B. purgans.
We must conclude that there is no type of B. ciliatus in the herbarium and that the
specimens marked ‘47’ are not types of this species. We can thus retain the name for
the species as described in our manuals and in Shear’s Monograph. As to B. purgans,
Linneus’s description does not distinguish between the three specimens; that is, be-
tween B. purgans and B. latiglumis. Of these three specimens, two are marked ‘‘ H
U,” indicating that they were cultivated in the garden at Upsala. The third speci-
men, marked ‘kK 4,’ is the only one collected by Kalm. This plant, which is Bromus
purgans as commonly understood and as described in Shear’s Monograph of Bromus,¢
should be taken as the type, in spite of the 4’? placed upon the sheet by Linneus,
probably inadvertently. In the Stockholm herbarium are two specimens marked B.
purgans.€ The second specimen, marked by Solander, is B. latiglumis (Scribn.)
Hitche. The other, marked by Linnzeus ‘‘H U 4’’ and ‘te semine Canadensi,’’ seems
to be the same, though it is only a panicle.

Bromus ciliatus L. Sp. Pl. 76. 1753.

There is no type specimen of this species. The specimens marked **4,”’ that is, B.
etliatus, which is the fourth species of Bromus, do not agree with Linnzeus’s descrip-
tion. The original Linnean description applies to Bromus ciliatus as currently under-
stood and as described in Shear’s Monograph of Bromus./ For a further discussion of
this species see notes above under B. purgans.

Stipa avenacea L. Sp. Pl. 78. 1753.

The type specimen is from Gronovius, as it bears his diagnosis, ‘‘ Hordeum spice
tenuiorl,”’? ete. Tt is also marked by Linneeus ‘3 capillata,’’ but does not bear the
name avenacea. Apparently Linnzeus intended first to name the species capillata,
but subsequently adopted the name avenacea. This specimen and that of the Grono-
vian herbarium (Clayton no. 621) are Stipa avenacea as generally understood.

AMERICAN GRASSES DESCRIBED BY LINNZEUS. 123

Avena pensylvanica I. Sp. Pl. 79. 1753.
The type specimen, marked “3 K pensylvanica,” is Trisetum pennsylvanicum (L.)
Beauv.

Avena spicata L. Sp. Pl. 80. 1753.

The specimen is marked ‘‘ K 10 bromoides.’’ The word bromoides has been scratched
out with pencil. Since the plant is Danthonia spicata (L.) Beauv. and answers to the
description of his Avena no. 10, A. spicata, we may assume that this is the type and
that there was some error in marking the name bromoides on the sheet. Linnzeus
later describes an Avena bromoides from Europe, a different species.

Arundo phragmites L. Sp. Pl. 81. 1753.

This is based on European material, but there is a reference to Gronovius. In the
first edition of Gronovius the number of Clayton’s specimen is given as 481. In the
second edition the number is 581. Clayton’s specimen is numbered 581. It is
Phragmites phragmites (L.) Karst. (P. communis Trin.).

Aristida americana L. Syst. Nat. ed. 10. 2: 879. 1759.
The type specimen, from “Br,’’ is Bouteloua americana (L.) Scribn. (B. litugiosa
Lag.).

Elymus canadensis I. Sp. Pl. 83. 1753.

The type specimen is not the form described as E. canadensis in recent manuals,
but is the allied glaucous form which has been distinguished as E. glaucifolins Muhl.
For a discussion of this specimen see note below under EF. philadelphieus.

Elymus philadelphicus L. Amoen. Acad. 4: 266. 1759.

One sheet is marked by Linnieus ‘‘philadelphicus 3” and ‘HU.’ Under the
latter appears to be the word ‘‘Canada.’’ The figure 3 appears to be crossed out.
This is the glaucous form called FE. glaveifolius Muhl. It has a large, pendulous
spike, with diverging awns, and blades 1.5 to 2 cm. broad. This is apparently the
specimen Linnaus describes under E. canadensis, which is Elymus no. 3. The
diagnosis reads ‘‘spica flaccida-pendula.’’ A second sheet has a specimen of the same
species, but with erect spike and ascending awns. Linnzeus has not written upon
this, but there is a transcription of the diagnosis of 2. canadensis and also “Elymus
canadensis, Spec. 3. p. 83,’’ and, “‘ex seminibus canadensis in hortulo meo [then an
illegible word] 1753” followed by “Leche” in pencil. Leche was professor at Abo.
At the Stockholm herbarium there are also two sheets, one marked ‘“ Elymus phila-
delphicus” by Solander and the other “3” by Linneeus and ‘3 canadensis” by the
younger Linneeus. Both are E. glaucifolius, but the second is less glaucous, the
spike not quite so stout, the awns more ascending. The two specimens correspond
very well to the two in the Linnean herbarium at London, except that the one marked
“philadelphicus” at the former place is erect and at the latter place is nodding. It
will be noted that in the description of FE. philadelphicus it is distinguished from EF.
canaderisis by having a nodding spike and more flexuous awns. While jt seems clear
that at the time of describing E. philadelphicus Linneeus wished to apply this name to
the nodding form and the name £. canadensis to the erect form, yet we are left in doubt
as to the types of the two. The figure 3 on the specimen in the Stockholm herbarium
with erect spike and ascending awns, and marked ‘‘canadensis” by Linnzeus fil., is
said by Lindman @ to have been written by the elder Linneus. The latter has not
marked any specimen with the name canadensis. I suspect that the history of the
specimen is about as follows: Both forms were growing in the Hortus Upsalensis.
Linneus described E. canadensis from the nodding form, and marked the specimen in
his herbarium ‘3,’ Later*he distinguished between the two forms in his garden and

decided to call the erect form canadensis. So he crossed out the “3” on his specimen
and wrote ** philadelphicus,’? but did not mark a specimen ‘‘canadensis.’”’ In this
case the specimen marked ‘“philadelphicus” is the nomenclatorial type of both.
Each is described in the second edition of the Species Plantarum, but here he fails to
distinguish between them. He copies the diagnosis of E. philadelphicus, but not the
distinction he has made between that and 2. canadensis. He also copies the descrip-
tion of FE. canadensis and distinguishes that from £. sibiricus without mentioning
E. philadelphicus. There is no doubt that all the specimens considered above are the
same species, 4. glaueifolius Muhl., which name must give way to EF. canadensis.
Heretofore the green form with more slender spikes has been considered typical F.
canadensis. E. philadelphicus becomes a synonym of E. canadensis. It is interesting
to note that in an article on ‘ Demonstrationes Plantarum,” @ in which Linneus
gives a list of plants cultivated in the Upsala garden, he says concerning FE. canadensis,
“Duplex in Horto occurrit: alter spica incurvata, alter spica pendula ut in E. sibirico,
sed structura plantae vix admittit differentiam specificam.’’

Elymus virginicus L. Sp. Pl. 84. 1753.

The type specimen is marked ‘4 virginicus.”’ Glumes and lemmas smooth, the
former about 1.5 em. long, including the awn point of about 5 mm., the latter with
awns | tol.5cem. long. The Clayton specimen (no, 446), corresponding to the Gronovian
synonym cited by Linnzeus, is not in the British Museum.

Elymus hystrix L. Sp. Pl. 560. 1753.

The type specimen is from Gronovius. Linnzeus has written upon it “6 Hystrix.”’
The specimen in the Gronovian herbarium at the British Museum (Clayton no. 570)
is the same, Hystrix hystrix (L.) Millsp. ( Hystrix patula Moench.).

Coix dactyloides L. Sp. Pl. 972. 1753.

The type specimen is marked “2 dactyloides HU.’ Linneeus later includes this
species in his new genus Tripsacum,? of which it is the type. The specimen is the
ordinary form of Tripsacium dactyloides (1..) L. with three spikes.

One specimén marked by Linnweus * Zizania HU’? and another marked “1 aquatica”

blades are not over 7 or 8 mm. wide. Linnweus gives two synonyms, CGronovius’s

Later Linnieus described a second species, Z. palustris. There is no specimen
in the herbarium marked thus. The description is quite ample. but the only
character given which would enable us to tell which form he had in mind is
that the leaves are wider than those of Arundo phragmites. The latter (Phragmites
phragmites (1..) Karst.) has blades rarely as narrow as | em. and usually 2 or 3 em.
wide. We may conclude, then, that he is describing the wide-leaved form, or what

we have been calling Zizania aquatica. The description of Z. aquatica as given by
Linnieus is very short, “ panicula effusa,’’ and would apply to either form. He prob-
ably did not then distinguish between the two. Both synonyms refer to the broad-
leaved form and the habitat given is Jamaica and Virginia, where the narrow-leaved
form is not known to occur, However, it seems evident that the only plant that Lin-
nveus saw was the narrow-leaved form, His description was short because he thought
there was but one species. The fact that later he described the broad-leaved form as
a distinct species confirms the opinion that his idea of Z. aquatica was the narrow-
leaved species. Consequently we must call the narrow-leaved species Zizania aquatica
L. and the broad-leaved species Z. palustris L.

Pharus latifolius lL. Syst. Nat. ed. 10. 2: 1269. 1759.

Andropogon divaricatum I. Sp. Pl. 1045. 1753

The type specimen is marked “2 divaricatum’’ and is from Gronovius. As pointed
out elsewhere, this is the sameas A. alopeewroides L.. which isan Erianthus. It should
be called Erianthus divaricatus (L.) instead of Erianthus alopecuroides (L.) Ell.
Linnzeus also cites a synonym from Gronovius which is based on Clayton no. 600.
This is Sorghastrum linnaeanum (Hack.) Nash,

Andropogon nutans L. Sp. Pl. 1045. 1753.

The type specimen is marked “3 K nutans.”” It agrees with Linnzus’s diagnosis
and is Sorghastrum nutans (L.) Nash, as described in Small’s Flora. The panicle is
rather compact and the awn bent once. On the back of the sheet is a reference to
Gronovius, “ Lagurus Clayton 600,’’ but, as indicated above, that is S. linnaeanum
(L.) Nash. Linneus cited two synonyms of his Andropogon nutans, one trom Grono-
vius based on Clayton no, 621, which is Stipa avenacea L., and one from Sloane (plate
14, figure 2), which is Valota insularis (L.) Chase (Andropogon insulare L.; Paniewm
leucophaeum H. B.K.).

Andropogon alopecuroides L. Sp. Pl. 1045. 1753.

The type specimen is a Gronovian plant and bears Clayton’s number 601. The
corresponding specimen of Gronovius’s herbarium is the same, Erianthus alopecuroides
(L.) Ell, but should be called FE. divaricatus, as indicated above in the discussion of
Andropogon divaricatum LL. Linneeus here ¢ also cites Sloane’s plate 70, figure 1,
which is fim perata caudata Trin.

Andropogon virginicum L. Sp. Pl. 1046. 1753.

The type specimen is marked ‘7 virginicum,’? but without indication as to its
origin. It belongs to this species as usually understood. Gronovius’s specimen
(Clayton no. 460) is the same. A second sheet in the herbarium from ‘“Br.”? is A.
leucostachys T.B.K. Linnzeus4 cites Sloane’s plate 68, figure 2, which is Andropogon
leucostachys Hl. B. hk.

Andropogon bicorne L. Sp. Pl. 1046. 1753.

The type specimen marked by Linnzeus belongs to the West Indian species known
by this name. A second sheet with a Gronovius label and numbered 602 is A. sco-
parius Michx. The diagnosis of Gronovius, based on this latter specimen, is cited by
Linneus under sf. hirtwm, an Old World plant, but not under A. bicorne. Clayton
no, 602 in the Gronovius herbarium is also A. scoparius Michx. The Gronovian
synonym given by Linneeus under sl. bicorne is supported by a plant in the Gronovian
herbarium (Clayton no. 606) which is Andropogon glomeratus (Walt.) B.S. P. Lin-

Andropogon ischaemum I.. Sp. Pl. 1047. 1753.

This is an Old World plant, but the only specimen in the herbarium is marked
“11 Ischaemum” and is A. furcatus Michx. This should not be taken as the type
of the species, since it is not the plant Linnzus describes.

Andropogon insulare L. Syst. Nat. ed. 10. 2: 1804. 1759.

The type specimen is from “Br.’’? It is Valota insularis (L..) Chase (Panicum leu-
cophaeum H. B. K.). After his own description Linnzus cites Sloane’s plate 14,
figure 2, which is also this species, but he does not use Sloane’s diagnosis.

Andropogon barbatum L. Syst. Nat. ed. 10. 2: 1805. 1759.

The type specimen, from ‘Br,’’ agrees with Linnzeus’s description. Tt was first
marked Andropogon fasciculatum; the specific name was scrat@hed and barbatum
written above. This latter name is also scratched and polydactylon written alter.
Both changes appear to have been made by Linneus. The plant is Chloris polydactyla
(L.) Sw., as described in Grisebach’s Flora.¢ Linneeus here cites Sloane, plate 65,
figure 2, which he earlier referred to Andropogon fasciculatum, but which in fact is
Chloris polydactyla, Later ® Linnzeus changes the name barbatum to polydactylon, citing
Browne and also the plate of Sloane just mentioned. Upon these grounds Nash forms
the name Chloris barbata (L.) Nash, ¢ but according to the recent code of nomenclature
this name can not be used on account of Chloris barbata (L.) Sw. Fl. Ind. Occ. 1: 300.

Andropogon fasciculatum L. Sp. Pl. 1047. 1753.

Munro@ states that there are two Linneean specimens marked with this name, one
being Hleusine indica and the other Pollinia ciliata. The only plant from America
bearing this name in the Linnzean herbarium is the sheet mentioned above under
Andropogon barbatum, in which the name fasciculatum was scratched. But this speci-
men is marked “‘Br’’ and presumably was not available when Linnaeus drew up his
original description, though the description applies well to this specimen, This
specimen is, no doubt, the basis of the Browne synonym cited in Sp. Pl. ed. 2. 1483.
1762, under A. polydactylon. Linneeus ¢ cites Morison, Gramen Dactylon indicum,
etc., but this is an Indian plant and has villous spikes, while Linnzeus remarks that
the spikes in his specimen are glabrous. The habitat is given in the original pub-
lication as ‘‘Indies,’’ that is, the West Indies. Linnaeus / doubtfully refers here
Sloane, plate 65, figure 2, which is Chloris polydactyla (L.) Sw., cited later under
Andropogon barbatumg and A. polydactylon.h We may therefore climinate these
two synonyms of Morison and Sloane, which are the only ones given. In the
Systema Naturae? Linnzeus retains A. fasciculatum along with his new A. harbatum
to which he transfers the Sloane citation. In the Pugillus Jamaicensium/ he does
not mention A. fasciculatum, but he gives A. barbatum, which is founded on the
Browne specimen. In the second edition of the Species Plantarum he still retains
A. fasciculatum with the original description and the Morison citation, introduces a
new citation (Browne Jam. 365), and changes the Sloane citation to plate 69, figure 2,
which is Paspalum virgatum. It is evident that the type of A. fasciculatum is not
from America in spite of the continued reference to American citations.

Holcus laxus L. Sp. Pl. 1048. 1753.

The type specimen is a Gronovian plant numbered 589, upon which Linnzeus has
written “6 laxus.’? It is Uniola lava (.) B.S. P. (Uniola gracilis Michx.). Clay-

The type specimen, which belongs to this species as usually understood, is marked
by Linneeus ‘“‘echinatus” without indication as to its origin. Following a number of
other synonyms Linnzeus4@ cites Sloane, page 108. The habitat given by Linnieus is
‘Jamaica, Curassao.”’

Cenchrus tribuloides L. Sp. Pl. 1050. 1753.

The type specimen, from “K,’’ is the large-burred species of the Atlantic coast
which has been called C. macrocephalus (Doell) Seribn. and to which the Linnean
diagnosis ‘‘C, glumis semineis globosis muricato-spinosis hirsutis’’ and habitat ‘‘in
Virginiae maritimis’’ better apply than to the inland plant that has been going under
the name tribuloides. The inland species must be called C. carolinianus Walt. The
Gronovian specimen (Clayton no. 206) is the same as the Linnean. Sloane’s plate 65,
figure 1, is cited by Linnzeus.b Sloane’s specimen is C. carolinianus Walt.

THE GRASSES OF GRONOVIUS’S FLORA VIRGINICA.

The herbarium of Gronovius is incorporated in the general her-
barium of the British Museum of Natural History. The specimens
upon which Gronovius based his dese ription in his Flora Virginica
were collected in Virginia by John Clayton. Each sheet usually
bears a diagnosis and the Clayton number, both of which are given
by Gronovius, thus connecting the Clayton specimens with the species
described in the Flora Virginica. The species are given below in the
sequence in which they occur in the first edition of Gronovius’s Flora
Virginica (part 1, 1739; part 2, 1743), the diagnoses being quoted
from that work. Many of these polynomials are cited by Linnxus
as synonyms under his own species in the first edition of the Species
Plantarum and are referred to in the discussion of the corresponding
Linnean species, in a preceding portion of this article.

THE GRASSES OF SLOANE’S HISTORY OF JAMAICA.

The grasses described by Sloane are preserved in the Sloane her-
barium at the British Museum of Natural History. The list given
below is in the same sequence as that of Chapter IV, of Sloane’s
History of Jamaica,° entitled ‘Of Herbs with grassie Leaves,’’¢
from which the diagnoses are quoted. Sloane’s plates are frequently
quoted by Linneus in the first edition of his Species Plantarum, but
in only a few cases are Sloane’s specimens the types of the Linnwan
species. In the following list it is so stated in connection with each
species, if the Sloane plate is cited by Linneeus, or if the Sloane plant
is the type of a Linnean species:

THE WEST INDIAN GRASSES DESCRIBED BY SWARTZ.

Olof Swartz collected in the West Indies, especially Jamaica, from
1783 to 1787. His collections are preserved in the Natural History
Museum at Stockholm.’ [is first account of his West India plants
was published in 1788 in a small work entitled ‘‘Nova Genera et
Species Plantarum, seu Prodromus Descriptionum Vegetabilium
Maximam Partem Incognitorum quae sub Itinere in Indiam Occi-
dentalem annis 1783-87 Digessit Olof Swartz.’ This work contains
the diagnoses of most of his new species of grasses. A few more
appear later in his more comprehensive work entitled ‘‘Flora Indiae
Occidentalis.” © In the later work the descriptions are considerably
amplified and often aid in identifying his earlier diagnoses. A few
of his tvpes of grasses are missing from his herbarium, ‘but i in all cases
I have been able to identify the corresponding species from his
descriptions or from authentic specimens distributed by Swartz to
other herbaria, such as those of Munich and Madrid. In this
article the species accredited to Swartz and published by Wikstrém
in Adnotationes Botanicae (1829) have not been considered except
when these are based on American material.

Clyra pauciflora Sw. Prod. 21. 1788.

The type specimen, labeled “Jamaica FI. ind. occ.,”’ belongs to this species as
generally understood.

Olyra paniculata Sw. Prod. 21. 1788.

Sacharum polystachyon Sw. Prod. 21. 1788.

No specimen of this could be found, but it is without doubt the species as generally
understood; that is, Paspalum saccharoides Nees, as described in Martius’s Flora Bra-

Leersia monandra Sw. Prod. 21. 1788.

No specimens of Leersia could be found that were types or in any way authentic.
This species and the following are probably correctly understood. This species is
now called Homalocenchrus monandrus (Sw.) Kuntze.

Leersia hexandra Sw. Prod. 21. 1788.
This is now Homalocenchrus hexandrus (Sw.) Kuntze.

Leersia oryzoides Sw. Prod. 21. 1788.

Paspalum conjugatum Berg.

This is included by Swartz in his Prodromus (page 21). No specimen of it was
found in the Stockholm herbarium, but there is at Madrid a specimen sent by Swartz
which belongs to this species as usually understood.

Paspalum vaginatum Sw. Prod. 21. 1788.

There are two Swartz specimens, on one of which is the name in the handwriting
of Swartz, but both are said to have come from Mauritius. They show the characters
that distinguish this species, as described in Small’s Flora, from P. distichum L. The
spikes are widely spreading or deflexed, the sheaths inflated, the spikelets smooth,
the midnerve of the glume on the convex side suppressed. On one specimen the
spikelets are 2.5 mm. long, on the other they are 4 mm. long. No specimen from
Jamaica was found that appeared to be authentic. In the Copenhagen herbarium is
a specimen sent by Swartz to Vahl which is without locality but is labeled Paspalum
vaginatum. This has pubescent spikelets and corresponds to P. distichum.

Paspalum filiforme Sw. Prod. 22. 1788.

No specimen of this could be found in the Swartz herbarium. At Munich there
are two sheets sent by Swartz labeled P. filiforme. One is Paspalum (Paspalus)
caespitosum Fliigge and the other is Syntherisma setosa (Desv.) Nash.c Neither of these
corresponds to the description of Swartz, which, as amplified in his Flora,@ is sufficient
to identify the species. It is the species described under this name in Grisebach’s
Flora, Fligge changed the name to Paspalus swartzianus because of his own Paspalus
filiformis (L.) Fliigge based on Panicum filiforme L.,¢ but Swartz’s name is valid,

Paspalum decumbens Sw. Prod. 22. 1788.

There is a specimen in the Stockholm herbarium and also specimens in the herbaria
of Berlin and Delessert sent by Swartz. All are the species as generally understood.
This has been called Paspalum pedunculatum Poir.,f which name must be used on
account of Paspalum decumbens Rotth. 1778. Panicum decumbens Roem. & Schult.g
is based upon Swartz’s species. Fournier has referred this to his genus Dimorpho-
stachys,” but the presence of an outer glume is too variable a character to be used as the
basis for separating this group as a genus.

WEST INDIAN GRASSES DESCRIBED BY SWARTZ, 137

Paspalum dissectum Sw. Fl. Ind. Occ. 1: 137. 1797.

Fliigge @ changes the name of this to Paspalus caespitosus on account of P. dissectum
L. (1759), which is a different species. The Swartz specimen is from Jamaica and is
marked P. dissectum Sw. and also P. caespitosum Fligge. It is P. caespitosum as
described in Grisebach’s Flora.

Panicum setosum Sw. Prod. 22. 1788.

The specimen in the Stockholm herbarium is Chaetochloa setosa (Sw.) Seribn. as
described by Scribner and Merrill.2— It is also described by Grisebach¢ under Setaria
setosa Beauy.

Panicum pilosum Sw. Prod. 22. 1788.

The type specimen is labeled ‘‘Jamaica, Swartz. fl. ind. occ.’ It belongs to the
species described under this name in Martius’s Flora Brasiliensis. It differs from P.
laxum in the densely flowered, comparatively short panicle branches (2 to 3 cm. long)
and in the pilose rachis. Panicwm distichwim Lam.¢ is the same, as indicated by the
type specimen at Paris labeled by Lamarck ** Panicum distichum lam. dict.’’ Another
synonym is Panicum pilisparsum G. F.W. Mey.¢ Inthe Trinius herbarium there is a
specimen of this sent by Meyer, apparently a fragment from the type at Géttingen.

Panicum molle Sw. Prod. 22. 1788.

The type specimen is labeled in the handwriting of Swartz ‘‘P. molle fl. ind. oce.’’
This specimen is not the species which has been generally described under this name,
but P. velutinosum Nees, fa South American species allied to P. fasciculatum Sw., and
not known to occur in the West Indies. The panicle is like that of Panicum reticulatum
Torr., while the spikelets are very much like those of Paniewm arizonicum Scribn. &
Merr. The spikelets are 3 mm. long, brown, sparsely reticulate-nerved, and finely
velvety-pubescent. The description in the Prodromus under P. molle is brief and
applies to this specimen, except that the branches of the panicle are said to be spread-
ing, while in the specimen they are erect-appressed. Swartz cites as a synonym
“Panicum 2. Brown. Jam. 133,’’ which is the plant commonly understood as Panicum
molle, that is, Panicum barbinode Trin. The locality is given by Swartz as ‘‘ India
occidentalis.” Swartz gives a more extended description in his Flora, where the
habitat is given as ‘‘in pascuis fertilioribus subhumidis Jamaicae.’’ We must decide
whether Swartz is describing the specimen he has preserved or whether he is describing
the forage plant of Jamaica, that is, the Browne plant. The description of the culm
applies to either except ‘‘inferne subdivisus” and ‘‘crassus,’’ which are not true of the
Swartz specimen but are true of P. barbinode, and ** pubescens,” which does not apply
to P. barbinode. The blades are said to be ‘‘ villosa, mollia,’’ which applies only to the
Swartz specimen. The spikes are described as ‘‘fuscis,’’ which applies to the Swartz
specimen and not to P. barbinode, on which the inflorescence is green or purple tinged.
Referring to glumes, ‘‘valvula exterior minuta” applies best to P. barbinode, as, in the
specimen, the first glume is half as long as the spikelet, and in P. barbinode only about
one-fourth as long. Second glume * pubescens” applies to the Swartz specimen; in
P. barbinode the spikelets are glabrous. The interior valve (palea) of the neutral
flower is said to be minute, but in both species it is well developed. The transversely
rugose fertile lemma common to both species is not mentioned. In a note Swartz
states that the species is distinguished by its soft pubescence and the thick, somewhat
succulent culm, for which latter feature it is much liked by cattle for fodder. He

further states that it is called in Jamaica Dutchgrass and is indigenous in Surinam.
Swartz probably thought his specimen to be the same as Browne’s plant, and, while he
described his own specimen, his description was modified by his knowledge of the
habit of the other species. Under these circumstances I think we should consider the
specimen in Swartz’s herbarium as the type of Panicum molle, which name should be
taken up for Panicum velutinosum Nees. A specimen in the Munich herbarium
labeled P. molle from Jamaica, sent by Swartz, is Panicum sloanei Griseb. or some
closely allied species. Iam not yet prepared to say whether or not Panicum numi-

dianum Lam. (1791) of Africa is the same as Panicum barbinode Trin. (1835) of Brazil.
They are made synonymous in Martius’s Flora Brasiliensis. In the type of P. numi-
dianum the spikes are rather loosely flowered, the rachis lacks bristles, and the lower
glume is half as long as the spikelet. According to Hooker,@ this should be Panicum
muticum Forsk.

Panicum fasciculatum Sw. Prod. 22. 1788.

There are two forms upon the sheet, which is labeled ‘Jamaica, Swartz. P. fasci-
culatum. fl. ind. occ.’ The chief specimen (which I accept as the type) is a good
match for Maxon no. 1659, collected in Jamaica in 1903. The spike-like racemes are
slender and 6 to 8 cm. long, the axis and pedicels pilose with scattered long, white
hairs. The spikelets are 2 mm. long, strongly reticulated, glabrous, rather dark
brown in color. The right-hand specimen, also P. fasciculatum, has a more compact
panicle, with shorter spikes and spikelets about 2.5 mm. long.

Panicum chartaginense Sw. Prod. 22. 1788,

The specimen is marked ‘Panicum chartaginense Fl. Ind. Occ. Swartz.’’ It is
the same as to floral character as the right-hand specimen of P. fascieulatwm men-
tioned above, and has compact panicles with spikes about 2 em. long. The habit of
the plant is somewhat different. The culms are more or less prostrate-spreading,
the leaves short and crowded and more or less pubescent, especially the sheaths:
the panicles are somewhat included at the base; the spikelets are 2.5 mm. long. The
general appearance is that of Panicum reticulatum Torr. of Mexico. This form can be
recognized as a subspecies under the name of Panicum fasciculatum chartaginense
(Sw.) Doell.6 (Panicum chortaginense Sw.; P. reticulatum Torr.)

Panicum nemorosum Sw. Prod. 22. 1788.
Tlie type specimen is marked by Swartz with the name and “fl, ind. oce.”’ It is
Ichnanthus nemorosus (Sw.) Doell.

Panicum acuminatum Sw. Prod. 23. 1788.

The type sheet is marked by Swartz “2. acuminatum fl. ind. occ, Jamaica.
Swartz.’’ The plants are all the autumnal state. This has recently been described
as Panicum comophyllum Nash, Bull. Torr. Club 80: 380. 1903.

Panicum rigens Sw. Prod. 23. 1788.

The type specimen is marked ‘‘P. rigens fl. ind. occ. Jamaica. Swartz.’’? It is an
Isachne, and is the same as that described by Grisebach in his Flora of the British
West Indies under the name of J. rigens Trin. Grisebach’s plant collected by Mac-
fadyen in Jamaica, preserved in the herbarium of Grisebach at Gottingen, is the same.
Isachne rigens Trin. is based upon Panicum rigens Sw. and the name of our plant is
Isachne rigens (Sw.) Trin. Gram. Pan. 252. 1826, although the plant described here
and in Martius’s Flora Brasiliensis appears to be Jsachne rigidifolia (Poir.) Urb. ( Ag-
rostis rigidifolia Poir. The type specimen of Agrostis vigidifolia Poir. was examined in
the herbarium at Florence. It has distichous, glabrous leaves, and rigid, spreading,
panicle branches quite different from those of Panicum rigens Sw. Sieber no. 265 from
Martinique is /. rigidifolia and is cited by Grisebach, indicating that he confused the
two species. Some of the plants sent by Swartz to other herbaria under the name of

a Fl. Brit. Ind. 7: 34. 1896, bIn Mart. Fl. Bras. 27: 205. 1877.

WEST INDIAN GRASSES DESCRIBED BY SWARTZ. 139

Panicum rigens are not the same as the plant in his own herbarium. The specimen at
Florence is J. rigidifolia. The specimen from the general herbarium at Stockholm,
which was seen by me at Halle, is Panicum acuminatum Sw. The specimen at Berlin
I think is the same as the original at Stockholm, though it has longer leaves, the blades
being 6 cm. or more long: but, as in the case of the other, the surface of the blades is
scabrous to the touch as described by Swartz. There are some points in Swartz’s
description which lead one to think that he had seen /sachne rigidifolia. He says,
in the more extended description in his Flora,@ ‘‘Gramen rigiditate peculiare.”’ But
in the original diagnosis in the Prodromus he states that the leaves are scabrous,
which applies to his specimen, but not to Isachne rigidifolia. Swartz’s type at
Stockholm is well matched by Fendler no. 1637 from Venezuela (U. S. National
Herbarium no. 822538).

Panicum fuscum Sw. Prod. 23. 1788.

The type specimen is marked “PP. fuscum Flor. ind. occ. Jamaica, Swartz.’’? The
panicles are small and compact like those of P. chartaginense Sw., and the spikelets
are like those of 7. fasciculatum Sw., but slightly larger. A good match for this is
Maxon no. 2361 from Jamaica. It should be considered a synonym of 2. fascicu-
latum.

Panicum laxum Sw. Prod. 23. 1788.

The type specimen is marked “ P. lavum fl. ind. oce. Jamaica. Swartz.’’ It belongs
to this species as usually described. Synonyms are: P. agrostidiforme Lam. 1791, type
at Paris marked ‘lam. ill. gen. ex D. Richard;” P. tenuiculmwm Meyer, 1818, portion
of type in the herbarium of Trinius at St. Petersburg marked ‘Prim. FI. Esseq.,”
sent by Meyer; P. diandrum Kunth, 1829, type in the Berlin herbarium, collected
in Guadaloupe by Balbis (the second specimen cited by Kunth, Rio Janeiro, col-
lected by Gaudichaud, is also in the Berlin herbarium); P. ramuliflorum Hochst.
in Steudel, Syn. Pl. Glum. 1854, type in the herbarium of Steudel at Paris. This
last specimen is also marked Agrostis nigrescens Salam. and is from Bahia. Steudel’s
cited specimen, Kappler Pl. Surin. no, 1523 is the same species (fide specimens seen
in various herbaria, such as those of Munich and Leipzig).

Panicum flavescens Sw. Prod. 23. 1788.

The type specimen is marked ‘‘P, flavescens fl. ind. occ. Jamaica. Swartz.”’ It is
the same as P. fasciculatum, The panicle is somewhat more open, but the branches
of the panicle are slender, about 8 cm. long, resembling in this respect the specimen
of P. fascieulatum rather than that of P. fuscum, but nearly devoid of bristles. The
spikelets are brownish, strongly reticulated, slightly exceeding 2 mm. in length.
Panicum flavescens as described by Grisebach® and by Hooker ¢ is very different,
being a species of the section Ptychophyllum,
Panicum diffusum Sw. Prod. 23. 1788.

The type specimen is labeled ‘“‘diffusum fl. ind. occ.,

Panicum lanatum Sw. Prod. 24. 1788. ,

The type specimen marked °P. lanatum fl. ind. oce. Jamaica. Swartz,’’ is allied
to P. divaricatum L. and P. sloanet Griseb. The species is characterized by the
densely lanose-velvety sheaths and blades. On account of the earlier Pantewm
lanatum Rotth. Deser, PL. 3.1776 ( Valota insularis (L.) Chase), I suggest for Swartz’s
species the name Panicum swartzianum (Panicum lanatwm Sw., not Rottb.).

Panicum arundinaceum Sw. Prod. 24. 1788.
There are two plants upon the type sheet, which is marked ‘ Panicum arundina-
one with a large spreading panicle, the other with

’

ceum fl. ind. occ, Jamaica. Swartz,’
a narrow compact panicle. The description applies better to the first, although they
are both Jsachne arundinacea (Sw.) Griseb.

Panicum polygamum Sw, Prod. 24. 1788.
The type specimen marked * Prodr.”’ is Panicum maximum Jacq., an earlier name,
which Swartz himself uses in his Flora.¢

Panicum glutinosum Sw. Prod. 24. 1788.
The type specimen marked °° 2. glutinosum fl. ind. oce.”? from “Jamaica. Swartz,”’
belongs to this species as generally understood.

Panicum trichoides Sw. Prod. 24. 1788.

There are two plants upon the type sheet, which is labeled “ trichoides fl, ind. oce.”’
from ‘Jamaica. Swartz.’’ The left-hand specimen is the form described as P. brevi-
folium in Grisebach’s Flora; the other is the same as the type of Panicum tricanthium Nees
in the Berlin Herbarium,examined at Halle. The leaf blades of the right-hand speci-
men are longer and the spikelets somewhat larger than in the left-hand one. Sloane's
plate? of Panicum brevifolium is cited by Swartz. Itis evident from the more complete
description given later in his Flora that Swartz considered his species the same as /’.
brevifolium L. and variable enough to include both the plants preserved, but wished
to change the name. The type of P. brevifolium L. is from India. The species is
shown by description and the specimen in the Linnzean herbarium to be P. ovalifolinm
as described in Hooker’s Flora of British India. Hence we may consider P. trichoides
Sw. as applying to the Tropical American species usually described as P. brevifolium
L. (P. ecapillaceum Lam, Tabl. Encyel. 1: 173. 1791), the left-hand plant being taken
as the type, and adopt Panicum trichanthum Nees for the larger form.

Panicum caespitosum Sw. I*l. Ind. Occ. 1: 140. 1797.

The type specimen marked “ 7’, caespitosum fl, ind, occ.’ from “Jamaica. Swartz”
is Panicum prostratum Lam., but, as shown previously (page 119), we should use the
name Panicum reptans L. for this species. The Mexican plant which has been dis-
tributed under the name 2. caespitosum in recent collections is a different species. ¢

¢ This was brought to my attention by Professor Mez, of Halle, for whom I propose
to name this species:

BRACHIARIA MEZIANA sp. nov.

Perennial; culms cespitose, glabrous, at first erect, 20 to 30 em, high; later branched
and decumbent becoming as much as 70 cm. long; leaves light green, sheaths densely
ciliate on the margin, sometimes sparsely pilose on the surface, blades 5 to 12 em. long,
5 to 10 mm. wide, moderately stiff and firm, glabrous or sparsely pilose on either sur-
face, ciliate on the margin near the base with papillose hairs; early panicles long-
exserted, later ones less so or scarcely exserted, consisting of several spike-like racemes
2 to 3 cm. long, along the upper 2 to 3 em, of the culm; spikelets placed with the
first glume toward the axis, arranged in 2 rows on one side of a somewhat flattened
narrow rachis interspersed with pilose hairs, nearly sessile, glabrous, 3 mm. long,
ovate, subacute; first glume ovate, 3-nerved, | mm. long, second glume as long as

Panicum hirsutum Sw. I'l. Ind. Occ. 1: 173. 1797.

The type specimen from “Jamaica, Swartz’’ is, as described by Swartz, a robust
plant with appressed-hirsute sheaths and a large, somewhat compact panicle about
20 cm. long, with glabrous acute spikelets about 2 mm. long. Pringle no, 5573 from
Mexico is the same.

Panicum kalmii Sw. Adnot. Bot. 6. 1829,
The type specimen, from Kalm marked 9. kali and also P. heterophyllum, is Pani-
cum sphaerocarpon Ell.¢

Panicum compactum Sw. Adnot. Bot. 14. 1829.

The type specimen is from Jamaica, snd belongs to this species as described by
Grisebach.® Grisebach describes this as a new species “Sw. Herb.,’’ overlooking
the description by Wikstrém in the Adnotationes cited above, There is an earlier
P. compactum Wit.,¢ but this is mentioned as a synonym under Panicum germanicum
and hence, not being actually published, is not a valid name. Ido not find that
Kitaibel’s name was taken up before the publication of P. compactum Swartz.

Milium compressum Sw. Prod. 24. 1788.

No specimen of this could be found, but the excellent description of Swartz in his
Florad leaves no room for doubt. It is the common pasture grass of the West Indies
called Paspalum compressum Rasp. and Anastrophus compressus Schlecht. The char-
acters of the species and its allies seem sufficiently distinct from Paspalum to warrant
the segregation of the group as a genus. Schlechtendahl suggested for it the name
Anastrophus. Axonopus Beauv. has been rejected by some authors on account of the
dubious characters assigned to it; and has been accepted by others for diverse groups,
usually centered around Panicum cimicinum Retz. Beauvoisé assigns four species to
this new genus, none of which he figures: Milium compressum, M. digitatum, M. cimi-
cinum, M. paniceum, Inanote he mentions another species, Aronopus aureus, which he
characterizes very briefly, and which he says seems to him asif it ought to belong to that
genus. He complicates matters somewhat by placing the mark of doubt in the index
after all the species of this genus except A. aureus. The type of the genus must be

spikelet, convex, prominently 5-nerved, sterile Jemma as long as s spikelet, flat « on
back, prominently 5-nerved, the first pair of nerves forming the angle of the incurved
edges, the second pair of nerves near the margin, sterile floret with three stamens and
a well-developed palea as long as the lemma, fertile lemma and palea minutely rough-
ened but not rugose, the former bearing a prominent apiculation about 0.5 mm, long,
Low moist places on the plains of Mexico,
Specimens examined:
Pringle 9592, Federal District, Cerro de Guadaloupe, altitude 2,770 meters, August
19, 1901; Palmer 533, 254; Conzatti & Gonzales 348; Bourgeau 222,439; Nelson
in 1893; Pringle 375.

Besides these specimens which are in the National Herbarium | have examined the
following cited by Fournier under P. caespitosum (Mex. Pl. 2: 18. 1886): Bourgeau 679,
Berlandier 575, 795, Lichmann 382, Schaffner 190, 317, Virlet 1309,

The type specimen is no, 156925 of the U. 8, National Herbarium (Pringle’s 9592).

The genus Brachiaria was established by Grisebach (in Ledeb. Fl. Ross. 4: 469.
1853) with a single species, B. erucaeformis (Sibth.) Griseb., which is the type,
Brachiaria differs from Panicum chiefly in having spikelets so placed that the fertile
floret stands with its palea toward the axis, i. e., with the first glume toward the
axis. The spikelets are subsessile in one-sided racemes, these racemose on an clon-
gated axis,

either Milium compressum Sw. or Axonopus aureus Beauv. I believe the former
should be taken as the type, though [ think the two species are congeneric. Swartz
species then should be known as Avonopus compressus (Sw.) Beauv.

Milium paniceum Sw. Prod. 24. 1788.
The type specimen is Syntherisma jiliformis (1..) Nash (Panicum filiforme L.).

Milium digitatum Sw. Prod. 24. 1788.

The type specimen is Syntherisma setosa (Desv.) Nash as described in Nash’s review
of Syntherisma.¢ The long-exserted peduncles bear 2 to 4 slender spikes, with narrow
rachis, It is well matched by Heller no, 4898 from Porto Rico and Wright no. 764
from Cuba. The spikelets are narrow, slightly exceeding 2 mm. in length. Swartz’s
name is earlier than the other names for this, hence the species becomes Syntherisma
digitata (Sw.).

Milium villosum Sw. Prod. 24. 1788.
The type specimen is Valota insularis (1..) Chase (Andropogon tnsilare L.; Panicum

Chloris petraea Sw. Prod. 25. 1788.

The type specimen belongs to this species as generally understood, and as described
in Grisebach’s Flora. Doell® changes the name of this to C. swartziana on account of
C. petraea Thunb., which, however, is a later name.

Chloris polydactyla Sw. Prod. 26. 1788.
This is based on Andropogon polydactylon L. The specimen belongs to that species.

No specimen of this could be found in the Swartz herbarium.

Chloris virgata Sw. Il. Ind. Occ, 1: 203. 1797.

There is no specimen of this. A cover was found marked with the name, but con-
taining nothing, and upon which some one has added an ‘‘0."’ From the description
it would appear to be the species represented by plate 18 in Martius’s Flora Brasiliensis,
vol. 2, part 3. Grisebach includes it under C. radiata in his Flora, but from this
species it is excluded by the statement in Swartz’s diagnosis ‘corollina exteriore
gibbosa, dorso apiceque ciliata.”

under this name in Grisebach’s Flora.

Andropogon fastigiatum Sw. Prod. 26, 1788.

The type specimen from “Jamaica, Swartz” belongs to this species, as described

There is no specimen of this at Stockholm from Swartz, but at Munich there is a
sheet of specimens from Jamaica sent by Swartz and marked ‘‘prodr,”? This is partly
A. brevifolium as generally understood and as described by Swartz, and partly A.
leucostachys H. B. K. In the absence of other evidence we may consider the Munich
specimen as the type, excluding the portion which is A. leucostachys.

Cenchrus setosus Sw. Prod. 26. 1788.

The type specimen marked “fl. ind. oce.”” is Pennisetum setosum (Sw.) Rich. as

Swartz’s type of this is not in his herbarium, but there is a specimen marked ‘‘ No.
17 Poa prolifera Sw. Carthagena Ins. Manzanillo, Febr. 1826 Billberg” which may
be a compared specimen, as it is in the Swartz herbarium. It is Hragrostis prolifera
(Sw.) Steud. as described in Grisebach’s Flora, This is the same as Sloane’s specimen
mentioned under Gramini tremulo affine, etc., and illustrated in his plate 71, figure 1.

THE GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA.

The plants collected by Andreas Michaux in North America in the
latter part of the eighteenth century, which form the basis of his
Flora Boreali-Americana published in 1803, are deposited in the
herbarium of the Muséum d’Histoire Naturelle at Paris.

The species are here considered in the same sequence in which they
occur in Michaux’s work. Following the name of the species as
published is the habitat as given upon the label accompanying the
corresponding specimen in the herbarium. The herbarium contains
the types of all except Dilepyrum aristosum Michx., Poa crocata
Michx., and Poa pectinacea Michx, Richard distributed some of
Michaux’s plants to other herbaria. Many of these duplicates are
found in the herbarium of Drake de Castillo at Paris. As will be
seen from the notes accompanying certain species in the following
list, it has not always been easy to determine which is the type
specimen, especially in the critical species of Panicum, In certain
cases the plant differs slightly from the description, or is from some
other locality than the one cited. These cases are considered upon
their merits in the notes accompanying each species.

Cinna arundinacea I..

There is a specimen of C. latifolia (Trev.) Griseb., which is the plant described, and
a panicle of C. arundinacea L. One label, which probably applies to the first speci-
men, reads: ‘A Sinu Hudsonis ad Pensylvaniam pracsertim in borealibus Canada

blepharophyllum Nash (2. debile Michx.; Ell. Bot. 8. C. & Ga. 1: 105, 1816.)

Paspalum ciliatifolium Michx.

“In Carolina, Georgia.’ There are three specimens on the sheet. One without
spikelets may be eliminated from consideration, also one with pubescent spikelets,
since the description states that the spikelets are glabrous. The third specimen has
ciliate blades, these somewhat hispid above, more so below, upper sheath ciliate on
the margin; spikes 2; spikelets glabrous, 2mm. long. This specimen, which I con-
sider the type, is in poor condition, but appears to belong to the species described
under this name in Small’s Flora.

Paspalum praecox Walt.
“A Carolina ad Floridam.’’ The specimen belongs to the species as described in
Small’s Flora.

Paspalum laeve Michx.
“In Georgia.’”’? The specimen, consisting of a single culm with three short spikes
and smooth foliage, belongs to this species, as described in Small’s Flora,

appears ‘to be described in Small’s Flora as 2. altissimum Le Conte. P. floridanum
as described in Small’s Flora is a taller plant, with hirsute sheaths and longer spikes.
It may be that these should be considered extreme forms of one species.

Paspalum plicatulum Michx.
“In Georgia, Florida.’’ The specimen belongs to the species commonly so called,

Digitaria sanguinalis [Scop.]

“A Pensylvania ad Caroliniam [sign for annual]. Syntherisma precox Walt.’
This is Syntherisma sanguinalis (L.) Dulac. (Panicum sanguinale L.) Michaux
cites no authority for his combination. It is to be noted that in his Flora he states
under habitat: “in cultis [sign for annual]: in Florida maritima [sign for perennial].’’

Digitaria pilosa Michx.

“In sabulosis Carolina, Georgia [sign for perennial].”” This plant corresponds to
the description, and the habitat is similar to that given in the book. The plant is
Syntherisma filiformis (L.) Nash. (Panicum filiforme 1.) A second sheet is referred
to below under Digitaria serotina.

Digitaria paspalodes Michx.

“In pascuis aridis Carolinae.”’ The specimen is Paspalum distichum 1. The
spikelets are pubescent.

Scribner,@ misunderstanding this species, transferred the name. to Paspalum as 2.
paspaloides (Michx.) Scribn., giving P. elliottii 8. Wats. (which is Paspalus furcatus
Fligge) as synonym. Nash > with the same conception of the species transferred the
name to Anastrophus as A. paspaloides (Michx.) Nash, but described P. furcatus
Fliigge under it. P. furcatus Fliigge becomes Avonopus furcalus (Fliigge) Hitehe. ¢

Digitaria serotina Michx.

There is no sheet thus labeled, but the plant evidently referred to here is in the
herbarium accompanied by a label ‘ Digitaria pilosa. Hab. in Carolina, Georgia.
Syntherisma serotina Walt.’’ (Compare note under D. pilosa.) This specimen
belongs to the species described in Small’s Flora as Syntherisma serotina,

Panicum glaucum L.

Michaux appends to his description the sign for an annual, but all the specimens
in his herbarium are Chaetochloa imberbis (Poir.) Seribn., a perennial species common
in the Southern States.

Panicum crus galli LL.
“Ad ripas rivorum Virginiae, Carolinae.”’ This is the tall form with somewhat
hirsute sheaths and long awns, now called ** Echinochloa walteri (Pursh) Nash.’

Panicum muricatum Michx.

“Lac, Champlain.” This specimen which is the type is Hehinochloa crus-galli (1..)
Beauv. A second specimen of the same is labeled, “in Canada, Connecticut [sign for
annual].”? Both have rather short awns, and small panicles like the introduced form.
Michaux distinguished this from the last, but applied Linnieus’s name to the wrong
species. Michaux’s specimen is also the type of Panicum pungens Poir.d

Panicum hirtellum I..

“In umbrosis sylvarum a Carolina maritima ad Floridam.’’ The specimen. is
Oplismenus setarius (Lam.) Roem, & Schult. as described in Small’s Flora.
Panicum molle Michx.

“In sabulosis maritimis Mlorida.’’ A second label, with diagnosis, reads ‘* Lieux
tres humides a 15 miles de St. Augustin.’”” The specimen is Eriochloa mollis (Michx.)

Kunth as described in Small’s Flora. There is only a panicle, but the pilose rachis
is characteristic. According to the American code Lriochloa mollis is not a valid name.
It must therefore be changed to Eriochloa michauxii (Roem. & Schult.). (Panicum
michauxti Roem. & Schult. Syst. Veg. 2: 427. 1817; P. molle Michx., not Sw.,
1788). I do not find sufficient evidence for taking up the name Monachne@ for this
genus, accepted by Nash.” Monachne is based on AM. unilateralis Beauv. and Sac-
charumreptans Lam. The former species has no description and can not be identified
from the plate, though it is evidently some species of Eriochloa, The latter does not
belong to the genus Eriochloa.

Panicum capillare L..
“A Pensylvania ad Carolinam,’’ This is similar to the Linnean plant, that is, the
large erect form with broad leaves, as commonly understood,

Panicum dichotomiflorum Michx.

This is the species which in the United States has been going under the name of
Panicum proliferum Lam. An examination of the latter plant in Lamarck’s herbarium
shows that it has been misunderstood. It is Panicum miliare of Asia. In the original
description ¢ the author states that the plant was cultivated in the jardin du Muséum
and that its native country was unknown, although he ventured the guess that it
might be from Virginia or some other part of North America. He also mentions seeing
specimens of this in Vaillant’s herbarium. The plant in Vaillant’s herbarium is the
same. This species was distributed in several of the larger herbaria under the name
of Panicum proliferum. Pursh took up this name for our plant and has been followed
by later authors. Michaux’s name appears to be the oldest for this. The type of
P. dichotomiflorum is in the herbarium of Drake de Castillo. It was sent by Richard,
having been collected by Michaux ” the type

oe

ad occidentem montium Alleganis,”’
locality as published. The specimen (a very poor one) in the Michaux herbarium
is labeled, ‘-in regione I]lineensium.’’

Panicum virgatum L,

“A Pensylvyania ad Georgiam ad ripas fluviorum, copiose in occidentalibus regioni-
bus [sign for perennial].’’ A second label reads, ** Pres le Debarquement du vieux
* * * Sur Coper River, Carolina, * * * Rare en basse Carolina.’ The speci-
men belongs to this species.

Panicum anceps Michx.
“Tn herbosis humidis Carolina, Virginiae, Georgiae [sign for perennial]. Mété avec
le P. melicarium.”’ The same as Panicum rostratum Muhl., a later name.

Panicum scoparium Lam.

‘In pratis sylvestris Carolina [sign for perennial].”° The specimen belongs to this
species—that is, Panicum viscidum Ell. (1816) and is identical with Lamarck’s
type, which was received from Michaux.

Panicum latifolium I..

herbarium is a sheet of specimens from Michaux sent by Richard. The left-hand spec-

imen is Panicum lanuginosum Ell. The other specimen is the same as the specimen of
P. pubescens in the Michaux herbarium. Lamarck mentions having seen a dwart speci-
men of this species in the herbarium of Vaillant, who received it from Sherard in 1721.
This specimen is in the general herbarium of the Paris Museum. I was not able to
identify this, but it is apparently different from any of our North American species.
Although this Sherard specimen is the first mentioned, I do not think it should be taken
as the type, as Lamarck was evidently describing Michaux’s plant, though the descrip-
tion is modified by the Sherard plant, e. g., “La tige qui quelquefois n’a guére plus
de six pouces de hauteur [the Sherard plant], s’éléve d'autres fois & la hauteur d’un
pied ou un peu plus.’”’ It is scarcely surprising that the vernal and autumnal states
of Panicum seoparium should be described as different species.

Panicum nitidum Lam.

“In Pensylvania, Carolina.’’ The specimen lacks spikelets, but is evidently
Panicum angustifolium Ell. or one of the closely allied species such as P. arenicoloides
Ashe. It is the vernal state, somewhat pubescent on lowermost. portions, otherwise
glabrous.

Panicum nitidum Lam. was first described in 1791.4 The description is very meager
and would not serve to identify the species. Only the panicle is described. The
plant was collected by Fraser. A somewhat more extended description is given by
Lamarck in the Encyclopedia,® but is only an amplification of the original with the
addition of leaf characters. We are told, for example, that the stem is jointed and
provided with leaves. The type specimen in the Lamarck herbarium consists of a
panicle and the uppermost joint of the culm with its leaf. The blade is reflexed,
and the node shows sparse reflexed hairs. It is Panicum barbulatum Ell., not Michx.
(P. subbarbulatum Scribn. & Merrill). The panicle is purplish. The most important
character given by Lamarck in his second description is the pubescence at juncture
of the blade and sheath. The label on this plant is “de la Caroline[.] Fraser.’ This
is evidently the type specimen. In the herbarium of Drake de Castillo there is a shect
obtained from Richard marked ‘Herb. Michaux from Pennsylvania’? which is
Panicum tenue Muhl. and probably is the specimen referred to by Lamarcke as
a small-flowered variety collected by Michaux in Pennsylvania. Panicum tenne is
not known to occur in Pennsylvania, and the location is probably an error. It will be
noted that the published locality for P. nitidum is “ Pennsylvania et Carolina,’’ which
accords with Michaux’s label. Richard in sending out the plant may have shortened
the locality to * Pennsylvania.’’ Panicum tenue Muhl. occurs from southern Virginia
southward, Scribner and Merrill @ have discussed Panicum nitidum Lam, and identi-
fied it with P. spretum Schult. (P. eatoni Nash and P. paucipilum Nash.). The figure
was taken from the plant in the Michaux herbarium, which, as stated above, is P.
angustifolium Ell. The name P. ntidum Lam. must be used for what has been called
P. subbarbulatum Scribn. & Merrill, while the plant described by Scribner and Mer-
rill as P. nitidum must be called P. spretum Schult.

Panicum barbulatum Michx.

There are three specimens and two labels upon this sheet. The label upon which
the name is written prominently at the top has “Hab. in Canada P. capillari affine ad
nipasamnis: Rivierre a Jacques Cartier dicti legi.’ The other has “ Rivierre a Jacques
Cartier Route a Queb. P. barbulatum.’? The twe larger plants are the vernal state of
P. gravius Witche. & Chase. There is also a small specimen of P.lindheimeri Nash.
In the Drake de Castillo herbarium is a specimen from Michaux sent out by Richard
which is labeled P. barbulatum, *Caroline.”’ This is Panicum ashei Pearson. There

is also on this sheet a small specimen of P. lindhetmeri Nash. There are two other
sheets from the same source, but without locality. One is P. verrucosum Muhl. The
other appears to be P. gravius Hitchc. & Chase, though it may be P. dichotomum. In
determining which plant shall be taken as the type it is to be noted that the locality
given in the description is ‘‘Carolina.’’ The only specimen having this locality upon
the label is the one in the herbarium of Drake de Castillo, which is P. ashet. The
description, however, mentions that the nodes are barbed, which applies to P. gravius,
the plant in the Michaux herbarium, and to none of the others concerned. The speci-
men in the Michaux herbarium (excluding the small plant P. lindheimert) has there-
fore been taken as the type, although it does not come from Carolina. Michaux evi-
dently confused several species, but we must surely apply the name to a species with
barbed nodes. The type is not what has been called P. barbulatum in all recent botan-
ical works. This latter species has a smaller spikelet (1.5 mm. long), while P. gravius
has spikelets 2mm. long. The plant commonly called P. barbulatum must take the
name P. microcarpon Muhl.; Ell. Bot. S.C. & Ga. 1816 (not Mubhl. Gram. 1817, which
is P. polyanthes Schult.).

Panicum ramulosum Michx.

“Tn pratis, cespitosis Carolinae.’’ A poor specimen without spikelets, but certainly
of the angustifolium group, apparently P. angustifolium Ell. This name antedates
any of those applied to P. angustifolium and its allies, but on account of the fragmentary
condition of the specimen it would not be wise to take it up. There is nothing
in the description which will identify the plant any more certainly. In the herbarium
of Drake de Castillo are two specimens from Michaux sent by Richard under this name.
One is P. dichotomum L., the other is P. lindheimert Nash. There is also a specimen
of the latter species in the Berlin herbarium sent by Richard under the name of
P, ramulosum.

Panicum melicarium Michx.

“Yn Carolina ad ripas rivorum affluviente mari inundatus [sign for perennial ].”’
The specimen is not a Panicum at all, but Panicularia elongata (Torr.) Kuntze. The
species has been much misunderstood and was rendered doubtful by the character
mentioned in the description of a sterile rudiment of a second flower, a character not
found in the genus Panicum. The spikelets of the specimen are past maturity and
consist of empty glumes or with the lowermost florets still attached. This floret
bears behind it the joint of the rachilla leading to the second floret, thus explaining
the character mentioned by Michaux. This species becomes Panicularia melicaria
(Michx.)

Panicum divaricatum Michx.

“Tn cespitosis excelsarum montium Carolinae Septentrionalis {sign for perennial ].”’
This is Festuca obtusa Spreng. (Ff. nutans Spreng.). Michaux doubted that this
was referable to Panicum. The spikelets are past maturity and like the preceding
species consist of empty glumes or with the addition of the lowermost floret, which
bears, of course, the joint of the rachilla. Michaux describes the spikelet as being
2-flowered, the second flower being a sterile pedicel. This species is of course quite
different from Panicum divaricatum L.

Agrostis juncea Michx.

“In aridis Carolinae.”? The specimen is Sporobolus junceus (Michx.) Kunth, as
usually understood,

Since Michaux’s name is untenable on account of Agrostis juncea Lam. 1783, this
species should be called Sporobolus gracilis (Trin.) Merrill, Rhodora 4: 48. 1902
(Vilfa gracilis Trin.). T have examined the type in the Trinius herbarium at St.
Petersburg, labeled ** Zimmermann imisit Carolina [836.’’

Agrostis dispar Michx.
“Tn Carolina inferiore.

a)

The specimen is -lyrostis alba 1.

Agrostis aspera Michx.

“THinois.”” The specimen is Sporobolus longifolius (Torr.) Wood, and not the
species to which the name Sporobolus asper (Michx.) Kunth has been applied in
recent manuals. The latter grass has an acuminate lemma and long-acuminate palea,
while Michaux’s description states that the flowers are muticous.

Apparently the earliest name for the plant which has been going under the name of
Sporobolus asper is Agrostis clandestina Spreng. Mant. Prim. Fl. Hal. 32. 1807, which
becomes Sporobolus clandestinus (Spreng.). Sprengel’s type has not been ex-
amined, but the description leaves scarcely room for doubt. The plant is described
as erect, and, what is particularly to the point, as having long-acuminate ‘corolla
glumes.”’ The plant was received from Muhlenberg, who also describes it in his
Descriptio Graminum. Both Muhlenberg and Torrey distinguished between this
and Agrostis involuta Muhl. (A. aspera Michx.; A. longifolia Torr.) using among
other characters the shape of the lemma and. palea, acuminate or awned in the first
and obtuse in the second.

Agrostis lateriflora Michx.

“In praecipitibus saxosis fluminis Misissipi ripariis Hlinoensibus [sign for peren-
nialj.”’ The specimen is Muhlenbergia mevicana (1..) Trin. The panicles are rather
dense, somewhat branched, and more or less included in the sheaths at base.

Agrostis racemosa Michx.

“In ripis sabulosis inundatis fluminis Misissipi [sign for perennial], Affinis A.
lateriflora.”” The specimen is Muhlenbergia racemosa (Michx.) B.S. P. Glumes
awned, longer than the acuminate lemma; panicle dense, more or less interrupted or
lobed.

Stipa barbata Michx.

“In sylvis Virginiae Carolinae [sign for perennial].’’ The specimen is Stipa avenacea
L. On this sheet is also a label which doubtless goes with the next, “Stipa sericea.
Hab. in Carolina, Georgia maritima.”

Stipa sericea Michx.

The specimen is Mihlenbergia capillaris (Lam.) Trin., as described in Small’s Flora.
Many of thesheets in Michaux’sherbarium bear two labels, one with name and locality,
the other with a diagnosis, and usually also the name written upon it somewhere as if
added later. The sheet of Stipa sericea bears a label with diagnosis and name, but the
other label seems to have been transferred to the sheet of 8. barbata, mentioned above.

Stipa juncea Michx.

There is no specimen with this label, but among the Avenas is a sheet marked
“Montagnes steril. a la hauteurs du Terres,’ which without doubtisthetype. It bears
the name Avena uniflora with the word jincea written above, and in the manuscript
diagnosis it is compared with Avena siberica L.,as is the case in the published description
of Stipa juncea, ThespecimenisStipamacountiSeribn. The description merely states
that the flower is aristate, but the diagnosis upon the sheet states that the awn is three
times as long as flower. Michaux’s name can not be used on account of the earlier

GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA. 151

S. juncea 1,., for which reason it was changed by Poiret to 8. canadensis.¢ Wence this
species should be called Stipa canadensis Poir. (Stipa macounii Scribn. in Macoun,
Cat. Can. Pl. 5: 390. 1890.) The species of Britton’s Manual described as Oryzopsis
juncea (Michx.) B.S. P. should be called Oryzopsis pungens (Torr.) (Milium
pungens Torr. in Spreng. Neue Entdeck. 2: 102. 1821.)

Erianthus saccharoides Michx.

There are two sheets of this, both labeled by Michaux, but no locality is given.
They belong to the species described in Small’s Flora under this name. This species
was described by Walter in 1788 as Anthoranthum giganteum. Wis specimen is
among the few grasses preserved in his herbarium at the British Museum. In both
types the panicle is tawny and the awn straight. The specific name can not be taken
up because there is an Erianthus giganteus Muh,’ based upon Andropogon. alope-
curoides Land described in his Descriptio Graminum.¢c The awn is there stated to be
twisted, asin the Linnean plant.

Erianthus brevibarbis Michx.

“Tn collibus desertis ab amnio Wabash ad Ostium Missouri 5 diebus distantibus.”’
The specimen belongs to the species described in Small’s Flora under this name. The
The known

range as originally published is ‘in collibus Tennassée et Carolinae.
range is from Delaware southward along the coast to Florida, and west to Louisiana.
We do not know of its occurrence in southern [linois, as given on Michaux’s label.

Holcus odoratus |.
“Tn pratensibus Canada [sign for perennial]..’ The specimen is Savastana odorata

Andropogon macrourum Michx.

“A Virginia ad Carolina [sign for perennial]."" The specimen is Andropogon glome-
ratus (Walt.) B.S. P. This agrees with Walter's specimen in the British Museum in
having roughened spathes, rather loose instead of tightly rolled as in the type speci-
men of Andropogon corymbosus (Chapm.) Nash (A. macrourus corymbosus Chapm.;
Hack. in DC. Monogr. Phan. 6: 409. 1889. Curtiss, N. A. Plants 3639¢).

Andropogon dissitiflorum Michx.
“In Carolina Georgia Florida.’’ The specimen is Andropogon virginicus Li.

Andropogon ternarium Michx.

“Tn regione Wabash Georgia montosa &e.’’ The specimen is Andropogon argyraeus
Schult. which is A. argenteus Ell., not DC. There isa single rather fragmentary speci-
men which is undoubtedly this species. Besides the label quoted above, the sheet
bears two others, but the name 1. ternariin is questioned upon both. One gives the
locality as “Wabash & Hlinois,’’ the other as Florida. As the diagnosis on the first of
these two labels states that the staminate flower is pediceled, 1. fureatus Muhl. may
be referred to. However, the published locality is “in montosis Carolinae.’”? Some
of the awns of the specimen are somewhat twisted. There appears to be no reason
why this name (as A. fernarivs) should not betaken upin place of A. argyraeus Schult.

Andropogon scoparium Michx.

The label bears the name, but no locality. The published locality is ‘in aridis
sylvarum Carolinae.”’ The specimen belongs to this species as generally understood.
The sheet bears another label with *‘ Andropogon avenaceum,”> which has evidently
been misplaced.

There are two individuals. One is slender, about a foot high, nearly glabrous
throughout, with a narrow rather compact panicle; the other, more robust, but con-
sisting only of panicle and upper leaf, is pubescent (under a lens) upon sheath and
blade. This panicle, which is attached to a label with “herb. de M. de Pinckney
11.2,” is lobed like the western form called S. obtusata lobata (Trin.) Scribn. The
first specimen should be taken as the type, as it no doubt represents Michaux’s own
collection from Florida. :

except as to the point that it was probably based on a species of Panicum. While
going through the Panicums of the De Candolle herbarium I found a specimen of
Panicum virgatum which was sent by Rafinesque and which was labeled Eatonia pur-
purascens. This is undoubtedly a duplicate type and fixes the identity of the genus
Eatonia Raf. The original description applies well to the common purple form of
this species found in brackish marshes along the coast.

Melica glabra Michx.

One label reads, ‘a Carolina ad floridam;’ the other reads, “florida f. Matanea No.
5.” The plants are glabrous and have a simple slender raceme of about ten spikelets.
Without much doubt M. mutica Walt. is the same.

Trachynotia cynosuroides Michx.

There are two labels, ‘I]inoensis” and “hauteurs des terres.’ The specimen
belongs to the inland species with several somewhat scattered spikes and awned
glumes, the lower being as long as the spikelet, which in most manuals is described
under Spartina cynosuroides (L.) Willd. Michaux’s description also applies to this
species. Michaux, however, takes up Linnieus’s specific name and bases his name
Trachynotia cynosuroides upon Dactylis cynosuroides L. As has been already pointed
out,@ the Linnean plant is the large seacoast form usually called Spartina polystachya
(Michx.) Ell. Thisname must become asynonym of Spartina cynosuroides (L.) Willd.,
while the plant of the inland marshes previously known by this name must receive a
different name. The name Spartina michauxiana is therefore proposed. for the
plant described by Michaux under the name of Trachynotia cynosuroides (not Dactylis
cynosuroides 1,.). It has been proposed to take up the name Spartina pectinata Link,
Jahrb. Gewiichsk. 1°: 92. 1820, but S. pectinata was collected by Bosc probably in
South Carolina, where 8. michauriana does not grow.

Trachynotia polystachya Michx.

“Basse Caroline.’’ Another label reads, “Trachynotia (a dorso valvarum scabro)
Dactylis cynosuroides L.”’ Since both this and the preceding species have scabrous-
keeled glumes, one suspects that the second label has been misplaced, or that Michaux
was uncertain as to the identity of Dactylis cynosuroides L. As stated under the pre-
ceding species, the name Spartina cynosuroides (1,.) Willd. should apply to this species,
since Michaux’s type of Trachynotia polystachya is identical with the type of Dactylis
cynosuroides 1.. Spartina cynosuroides Willd. is also founded upon Dactylis cynosu-
roides L. Both Michaux and Willdenow describe, through error of determination, a
different plant, that is, Spartina michauxiana Hitchc.

Trachynotia juncea Michx.

One label has the name only. A second label has “Dactylis sabulata bords des
Creeks salés Basse Caroline.’’ Spikes one or two; spikelets closely appressed upon
the rachis. The specimen is Spartina juncea (Michx.) Ell. as described by Merrill. ¢

The specimen

Eleusine mucronata Michx.

“linois.”” The specimen is Leptochloa mucronata (Michx.) Kunth as described in
the manuals.

This is the same as Leptochloa filiformis (Pers.) Roem. & Schult. (Eleusine filiformis
Pers. 1805.), the type of which is from ‘“‘Americ. meridion.’’ It may be the same as
Festuca filiformis Lam. 4@ from ‘Amer. merid, Comm, D. Richard.’’ The description

is insufficient for identification and the type has not been examined. The species
does not appear to be described by Lamarck in his Encyclopedia. The name
Leptochloa filiformis has been applied to the species of southern Asia, which I think is
different from our species.

e
Elymus virginicus I..

There is no locality given. ‘The specimen is similar to the Linnean type, having
smooth lemmas and awns 2 to 2.5 em. long.

Bromus canadensis Michx.
“Canada: Lac St. Jean.’ The specimen is Bromus ciliatus L. lemmas pubescent
on the margins, glabrous on the back,

Festuca myuros |..”

“Env. de Charleston.”’ There are several specimens on the sheet. Some are
Festuca octoflora Walt.; some are F. seturea Nutt., the lemmas pubescent toward apex.
The description apples to the latter.

Festuca bromoides I..?

“In pascuis Juxta Charleston.”

The specimen is Festuca octoflora Walt.

Festuca fluitans I.
“Canada, Connecticut, Pensylvania.”’ The specimen is Panieularia borealis Nash,

Festuca polystachya Michx.
“Tlinois.”’ The specimen is Leptochloa fascieularis (Lam,) Gray, the erect short-
awned form.

Festuca distichophylla Michx.
“In maritimis Carolinae.’’ The specimen is Distichlis spicata (L.) Greene, stami-
nate form.

Festuca poaeoides Michx.

“In Canada [sign for perennial] “Herb. de M. Jussieu Fleuve St. Laurent.”’
The specimen is Festuca elatior L., the small form with slender panicle sometimes
known as F. pratensis Huds.

Festuca diandra Michx.

“[linois.”’ The specimen belongs to the species described as Diarrhena americana
Beauv. in Gray’s Manual and Korycarpus diandrus (Michx.) Kuntze in Britton’s
Manual. The specific name is invalidated by Festuca diandra Moench. Korycar-
pus was substituted for Diarrhena by Kuntze & on the strength of a citation by
Lagasca (“Norye. arundinaceus Ze. Ac. Matr. 18067° Lag. Nov. Gen. 4. 1816).
Tam unable to find any evidence that this name was published earlier than 1816,
In the absence of such evidence it is best to use Diarina festucoides Rat, Med. Repos.
5: 252. ISOS, based on Festuca diandra Michx.

Poa capillaris |.

“Carol.”’ The specimen is Fragrostis refracta (Muhl.) Scribn.

Poa crocata Michx. ;

No specimen of this could be found, The description applies to Poa triflora Gilib,
(P. serotina Erhr.).

Poa hirsuta Michx.

“Carol.’’ The specimen is Eragrostis hirsuta (Michx.) Nash as described in Small’s
Flora.

@Meth. 191. 1794. bRev. Gen. 2: 772. 1891.

GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA, 155

Poa seslerioides Michx.

The name does not appear on the label, but a sheet which answers to the descrip-
tion bears the locality “‘Carol.”’ The plant is 7'ridens flava (L.) Hitehe. ( Triodea
cuprea Jacq.) .@

Poa compressa I.

“Environs de Montreal et La Prairie extremité du lac Champlain.’ The specimen
belongs to this species.
Poa stviata Michx.

“Pensylvania, Virginia, Carolina.”’ The specimen is Panieularia nervata (Willd. )
Kuntze (Poa nervata Willd. 1797). | .

Poa pectinacea Michx.

No specimen of this could be found. This is unfortunate, as the species is some-
what uncertain. The description points toward the species generally understood and
described under the name Eragrostis pectinacea in our manuals. But this is a peren-
nial, while Michaux places the sign for annual after the locality, which is given as
Illinois. Research in other herbaria at Paris, such as the General Herbarium and the
herbarium of Drake de Castillo, may yield specimens collected by Michaux and sent
out by Richard, which will determine the identity of the species.

Poa reptans Michx.

“Rivierre Kaskaskia in limosis ripariis hujus amni,” the pistillate plant. “In
limosis ripariis amnium regionis Illinoensibus [sign for annual], the staminate
plant. These are Eragrostis hypnoides (Lam.) B.S. P. Lamarck ® states that his
plant is the same as the one collected by Michaux on the Kaskaskia. Lamarck’s
first description of this, Poa hypnoides, appeared several years earlier.

Uniola latifolia Michx.

“THlinois.”’ This belongs to this species as described in our manuals. No speci-
men was found from the published locality, the Alleghany Mountains.
Uniola gracilis Michx.

No locality is given. The same as //oleus larus L. in the Linnean herbarium, now
called Uniola lava (.) B.S. P.

Uniola maritima Michx.
“Carol. sur la bord de lamer. Sea-side oat.”? ‘Phe specimen is (ntola pantenlata L.

Briza canadensis Michix.

No locality is given. The specimen is Panicularia canadensis (Michx.) Kuntze as
described in Britton’s Manual.
Briza eragrostis |..

“Carol”? The specimen is Eragrostis crayrostis (1..) Karst. ( Eragrostis megastachya
(Koel.) Link).

Avena mollis Michx.

“Montreal.”? The specimen is Trisetim spicatum (L.) Richter (T. subspicatum
(L.) Beauv.) The sheaths and blades are pubescent. In some manuals the glabrous
form is given this name while the pubescent form is made a variety. However, the
Linnzean specimen of Aira spicata is pubescent.

Avena glumosa Michx.

“A Canada et Carolina [sign for perennial|.”’ The specimen is Danthonia spicata

(L.) Beauv. The plant is glabrous,

Avena palustris Michx.
“Georgia Lieux humides.’’ The specimen is Sphenopholis palustris (Michx.)
Seribn. ( Trisetum palustre (Michx.) Torr.).¢

Avena striata Michx.

“A sinu Hudsonis ad Lacus Mistassins,’’? “Lac des Cygnes, Montagn. ent. la Baye
de Hudson et le Canada Mistassins.”’ The specimen belongs to this species as gen-
erally understood, It is, however, a Melica and would be, according to the Vienna
Code, M. striata (Michx.) Hitehe.6 By the American Code this name is invalidated
by Avena striata Lam, 1783, and must be changed to Melica purpurascens (Torr. )
(Trisetum purpurascens Torr. Fl. U.S. 1: 127. 1823; Avena striata Michx., not Lam.).

Arundo canadensis Michx.
“A Sinu Hudsonis ad Canadam praesertim ad ripas lacuum [sign for perennial ].”’
The specimen is Calamagrostis canadensis (Michx.) Beauv. as described in our manuals.

Arundo arenaria I..
“Ad ripas fluminis 8. Laurentii a mare affuvienti inundatus.”’ The specimen is
Ammophila arenaria (1..) Link.

Arundinaria macrosperma Michx.

“Gramen altissimum ramosum a Virginia ad Floridam & in occidentalibus juxta
fluviis ab Ilinoensibus ad ostium Misissipi [sign for undershrub].’? The specimen
is fragmentary and one can not be certain which species of Arundinaria it represents.
Michaux probably included the large and small canes in one species. As he described
the plants as being very high, we may retain this names for the tall cane, as is done in
our manuals,

Zizania miliacea Michx.

There is no sheet bearing this name, but the plant described by Michaux bears the
label © Zizania palustris,” without locality. It is Zizaniopsis miliacea (Michx.) Doell
& Aschers as described in Small’s Flora.

Zizania clavulosa Michx.

This name does not appear upon any sheet, but a corresponding specimen, answer-
ing to the description, is marked Zizania aquatica, * Lac Champlain New Jersey Caro-
It is Zizania palustris L., the large, broad-leayed form.

”

lines Illinois & Lac d’Am.

Zizania fluitans Michx.

“In stagnantibus Carolinae Georgiae et alibi copiosissime juxta Charleston.”” The
specimen is Hydrochloa carolinensis Beauv. (HI. fluitans (Michx.) Nash.) Michaux’s
specific name can not be taken up on account of the earlier H, Jluitans Hartm.
Michaux’s published locality, “ad lacum Champlain,’? must be an error, for the plant
is not known to occur in the north.

Manisuris granularis Sw.
“In Carolina.’ The specimen is [/ackelochloa granularis (L.) Kuntze.

PREFACE.

During the past few years much study has been bestowed upon plants
which furnish the rubber of commerce. This has shown that many of
these are unknown botanically, that those which have been described
have often been placed in wrong genera, and that the number of genera
and species which may furnish rubber is apparently much larger than
has been supposed. It has been discovered not only that several speties
of the genus Sapium produce a part of the rubber of commerce, but
that the genus is a very large one, and it will doubtless be found that
more of its species are capable of yielding a satisfactory raw product.

The accompanying paper on the species of Sapium of Mexico and
Central America, by Mr. Henry Pittier, is therefore, in view of the
growing demand for more rubber, timely, and the contents are such
as to make it an important contribution to this subject. Most of the
new species here proposed were first studied by Prof. Karl Schu-
mann, but his death occurred before they had been published, or even
manuscript upon them prepared. Mr. Pittier has described the new
species recognized by Professor Schumann, together with two addi-
tional species distinguished by himself, and has added, with appro-
priate notes, descriptions of two already known. .

THE MEXICAN AND CENTRAL AMERICAN SPECIES
OF SAPIUM.

By Hewry Pirvier.

INTRODUCTION.

Among the Costa Rican species of Sapium there is one common in
the central valley of San José and known to the natives under the
name of yds or 7és, a word that probably originated in the extinct
Guetarti language. The milk of this species is used by boys as a bird-
lime.* Small sticks are smeared with the fresh milk and placed near
some food that will attract the birds, and if any of these happens to
alight on one of the sticks, its feet adhere so strongly that it can not
fly away. With the object of ascertaining the presence or absence of
rubber in the milk of that species, I started a few years ago some pre-
liminary investigations. The subject of my first few experiments was
a tree growing in a hedge near San José. Its trunk was about 80 cen-
timeters in diameter, and it measured nearly 3 meters from the ground
to the limbs, but it had been kept cut back with the hedge, so that the
ramification was all new growth with very large, fleshy leaves. These
furnished an abundance of a watery latex which, after desiccation, was
found to contain traces of rubber and a very large amount of a sticky,
resinous substance. Later I realized through personal experience the
fact, already very well known, that the milk of young Castilla trees
and other rubber plants also yields mostly resinous substances and
comparatively little rubber, so that the conclusiveness of these first
experiments against the utility of the Costa Rican Sapium became
doubtful.

I had no opportunity, however, to continue my researches under
better conditions and had almost adopted the opinion that none but the
high Andean species of Sapium, known from Colombia and Ecuador,
were rubber-producing trees, when my attention was attracted by
various articles from different sources, all of which contributed to
throw new light on the really important réle of several species of this
genus as contributors to the suppl) Vv of South Amer! ican rubber.

a The milk was used for the same purpose in “Jamaica. “(See footnote, p. 162.)

As early as 1901 Dr. J. Huber, at present director of the Museu
Goeldi at Para, called attention to several rubber-yielding species of
Sapium from the Amazon basin.“ His paper was apparently ignored
by Professor Jumelle, who nevertheless gives in his book? an excel-
lent account of the Brazilian rubber-yielding fapuriv, or murupita,
which he also places, although with doubt, in the genus Sapium.
According to this author, much of the borracha, fina and entrefina,
coming into market through Manaos, and heretofore considered a
product of several species of Hevea, actually proceeds from the
tapurit, or murupita, tree.

Further investigations of Doctor Huber’ confirmed Professor Ju-
melle’s inferences and contributed several important additions to the
facts already known. At about the same time Dr. Ernst Ule?
increased by two the number of the Brazilian species of Sapium
known to produce rubber. In Ecuador and Colombia no less than
five species of this genus are known to yield good rubber, and in a
recently written article Mr. A. W. Bartlett’ states that the milk of
S. genmani Hemsl., growing in the lowlands of British Guiana, yields
a rubber of excellent quality, long known to the natives, and that this
constitutes to-day the bulk of the rubber supply of the colony. Thus
at least nine South American species of the genus Sapium are to-day
known to yield rubber, while the Central American species that have
scarcely been investigated botanically may contribute important addi-
tions to the list.

Shortly before leaving Costa Rica I received a small sample of an
apparently excellent rubber, said to have been extracted from Sapium,
or yds, trees, the exact location of which could not be given. This of
course had the effect of renewing my interest in the matter, and I
felt also stimulated to further investigations in that line by Doctor
Preuss’s discovery of several new rubber-yielding species of Sapium
on the Pacific coast of tropical South America” <A large number of
botanical specimens were collected both by myself and by my former
assistant, Mr. A. Tonduz, most of which were found to constitute new
species. ‘They were turned over to Dr. Karl Schumann for deter-
mination, but their systematic study was unfortunately interrupted
by the untimely death of that botanist, while my departure from
Costa Rica put an end to any further attempt on my part to ascertain
the economic value of these species.

MEXICAN AND CENTRAL AMERICAN SPECIES OF SAPIUM. 161

This is, I believe, enough to show on the one hand that the appar-
ent scarcity of Sapium species in and north of Costa Rica must be
attributed mainly to our deficient knowledge of the flora, and on the
other that there is really no reason why some of these unknown or
little-known Central American species should not also be found to
yield commercial rubber. It is in anticipation of further researches
on the subject that the present revision of the species known from
Middle America has been undertaken.

In the preparation of this paper I have used the material in the
United States Nationai Herbarium, and also in the collections that
were kindly loaned me by the Gray Herbarium, the Field Museum
of Natural History, Capt. John Donnell Smith, of Baltimore, and
the Instituto fisico-geogratico, of Costa Rica. The last collection con-
tained no less than seven new species, five of which had been named,
although not described, by Dr. Karl Schumann, Although it is not
unlikely that upon further investigation the number of these Costa
Rican species will need to be reduced, I prefer to maintain here
the specific divisions established by the lamented Berlin botanist.
Not long ayo one of the forms distinguished by him under the name
of S. pycnostuchys was described by Huber,” who gave it the less
desirable name of S. pittier?.

Regarding the general systematic treatment of the genus Sapium, it
must be said that it is still very imperfectly known. Not only are the
differences between the numerous species often very vaguely defined,
and many species have been included under one name, but even the
limits of the genus do not seem to be always understood, as there has
been a continual confusion between Sapium, Excoecaria, Sebastiania,
and Stillingia.’ This is due, without doubt, to the absence in most
herbaria of sufliciently extensive material.

“Bull. Herb. Boiss. IT. 6: 350. 1906.

’As understood to-day, the genus Excoecaria is limited to the Eastern Hemi-
sphere, with /. agallocha as the type species. It differs from Sapium by characters
of seemingly little importance and perhaps not yet well defined. Most of the species
are dicecious; the divisions of the male calyx are distinct, very narrow, and usually
three in number; the clusters of the male flowers and the pistillate flowers are pedi-
cellate, each cluster of the first seldom containing more than three flowers; the seeds
are smooth. Mueller of Argau (in Mart. Fl. Bras. 11°: 611-630) includes all the
American species in this genus, of which Sapium is then only a subdivision. But
this view has not been sustained by Bentham and Hooker and the more recent
writers.

Sebastiania is alsoa very near related genus, mostly from extratropical America. It
differs at first sight from Sapium by the reduced size of the plant, the absence of
petiolar and bracteal glands, the smooth seeds, and the bivalvate dehiscence of the
capsules. In Stillingia, another member of the same group, we note the absence of
the persistent axial column of the capsule and marked differences in the glandular
apparatus; also the American species of that genus are mostly extratropical and
somewhat distinct in their habits.

Asa general rule, the species of Sapium are exceedingly polymor-
phic. As in Ficus, the habit of the younger trees and the size and
texture of their leaves are quite distinct from those of old individuals.
On the same tree we have often large thick leaves on the young
shoots, medium-sized and rather coarse leaves on the branchlets of
older growth, and again small, narrow, and thin leaves at the base
of the new inflorescences. The general shape, the indentation of the
margin, and the glandular apparatus vary correspondingly. And
again, between trees of the same species but growing in distinct sta:
tions, we note striking variations in the same series of characters.
But this is not all; it is very likely that most of the species, if not all,
are proterandrous, the first flowers of the season being exclusively
staminate, while a second flowering that immediately follows shows
the usual androgynous spikes. This fact has given rise to the belief
that some species are dicecious, which is certainly not the case, at
least in the species of the subgenus Husapium.

The generic name Sapium was used for the first time by Patrick
Browne in 1756, being applied to one of the Jamaican species,
although without specific designation. In the second edition of the
same work, published in 1789, the Linnean name of ///ppomane glan-
dulosa” is given as corresponding to Browne’s ‘* gum tree,” but as
early as 1762 Jacquin® had upheld Sapium as a generic name and

«The Natural History of Jamaica 338. 1756. Browne gives the following account
of the genus without reference to any species:
‘““Saprom 1.—Arboreum, foliis ellipticis, glabris, petiolis biglandulis, floribus
spicatis.
“The Gum TREE.

“Flores alii masculini, alii feminini, in iisdem spicis; illi e superiore spicae parte,
oriuntur; hi vero infra enascuntur.
‘* Mas.

“Periantium nullum. Corolla nulla. Stamina: KE singula lacuna’ biglandula
emergunt filamenta quatuor, quinque, vel sex, brevissima; antheris globosis
instructa.

‘* Femina.

“Periantium: EF lacunis paucis biglandulosis, circa basim spicae digestis, emergunt

tariis referta.

“This tree grows te a very considerable size and yields a great quantity of resin of
a thick, sticky consistence, dirty color, opaque, and of little smell, which generally
serves for the boiling-house lamps in every part of the country where the tree is
frequent, and is much used for bird lime, which purpose it is observed to answer
extremely well. The wood is soft and coarse and not much esteemed.”’

identified the Jamaican Sapium with his 8. awcuparium. So it hap-
pens that although Browne’s publication was not made with all the
technical requirements, Sapium is generally accepted as a well-founded
genus, and the Jamaican species, S. car/baeum of the modern botanists,
is perhaps entitled to be considered as the typical one, unless Jacquin’s
true S. aueuparium, from Cartagena, be taken, on the ground that
it seems to be the first to receive a definite binomial name under the
genus. Later, several extra- American genera—among them Triadica,
Falconeria, and Conosapium, none of which I intend to discuss here—
were referred to this genus as subgenera. This is the view taken by
Doctor Pax in his treatment of Sapium in Engler and Prantl’s Pflan-
zenfamilien.@

In its restricted sense (Eusapium) the genus under consideration
includes large trees, with alternate smooth leaves usually bearing a
pair of glands at the base of the lamina and provided with caducous
stipules. Most species, if not all, are proterandrous, having a first
bloom with only male flowers, while in a second flowering, directly
following, occur both pistillate and staminate flowers. The inflores-
cence consists of spiciform, glanduliferous, terminal or axillary
racemes, growing either solitary or in clusters. On the androgynous
spikes the pistillate flowers are always at the base.

The staminate flowers are in clusters of at least three, but mostly
more in the Central American species, each cluster under a more or
less developed bract, with a pair of large, discoid, sessile glands. The
calyx is irregularly indented or lobed and includes two or three
stamens (always two in the species here described).

The pistillate flowers are solitary under each bract, but in variable
numbers (1-16) at the base of each spike. The calyx is usually bottle-
shaped and more or less deeply divided. The ovary is superior, three-
celled, with three styles, adnate at the base, or completely free.

The fruit is a three-coccous capsule, smooth outside, dehiscent. The
seeds are single in each cell, rather rounded or lentiform, and with a
more or less distinct caruncle. The albumen is carnose.

At present the genus Sapium includes about fifty-eight recognized
species, distributed all over tropical America from Mexico to Argen-
tina, with altitudinal ranges varying between 0 and 2,500 meters. — It
is likely that a goodly number of other forms have hitherto escaped
the attention of botanists. The present paper deals only with the nine
Middle American species known to-day.

These specimens were placed with S. pachystachys by Professor Schumann, but they
differ widely from that species in the form and texture of the leaf, their clustered

S. pleiostachys, with which it may prove identical upon examination of more complete

material.

The late Doctor Schumann labeled with the above name only no. 8857, while he
named no. 101128. biglandulosum Mill. Arg. This last number does not agree with
Muller’s description, and I fail to find a difference between the two specimens except
that in 10112 the leaf indentation is perhaps less obtuse and the base of the blade more
rounded and broader. The specimens of both numbers agree in their other charac-
ters and to my knowledge both represent the one common species met with almost
everywhere in the valley known as the Central Plateau of Costa Rica. The same
can be said of no, 2219, placed by Schumann in a third species, S. aucuparium Jacq.
This specimen consists merely of young leaves of what is certainly, according to my
experience, the species just described. Insufficient attention has perhaps been paid
to the fact that Sapium, like Ficus, Castilla, and some other trees, has much larger
leaves on shoots or on young specimens than on the adult individuals

face according to the age of leaf; floral branchlets slender and not ramified, growing
profusely on the thick, succulent twigs of the preceding year; floral spikes lateral or
terminal, androgynous or only staminate, probably in part caducous, 7 to 9 em.
long; floral glands oval; staminate flowers generally 5 in each cluster, the bracts

The salient character of this species seems to be its extreme variability, making it
difficult to give a very accurate description. Still, the rather long pedicels of the
mature capsules and the form of the seed are pretty constant and constitute a sharply
defined departure from the other Central American species. The seed characters
appear again, with more or less variation, in S. mexicanum and in the only species
known from Guatemala, the close aflinity of these forms being thus made evident.

In Hemsley’s description of S. /eferiflorum several particulars are mentioned that
can be found also in specimens of S. pedicellatum, as the thick floriferous branchlets
with thick pith, the lateral spikes with leafy peduncles, etc. But the former species
decidedly differs by the striking size of its leaves and its axillary spikes.

Professor Schumann (in schedula) called this species S. pycnostachys, and it is
unfortunate that this name can not be retained, as it referred to the thick-set appear-
ance of the fructiferous spike. The species is closely allied to S. oligoneurum and
S. anadenum and consequently to 8. aereum and its South American associates; it
differs from the first two by the peculiar disposition of the petiolar glands, and from
S. anadenum in particular by its subsessile, longer capsule, the outer shell of which
is also thinner and smoother,

This species is maintained, subject to revision when better information is secured,
on the authority of Schumann, notwithstanding the deficient material at hand. The
form of the leaves, if not their reduced size, and the apical gland suggest S. aereum
Klotzsch, but for the metallic sheen, which seems to be a constant character of the
leaves in the latter species. Also, the wide distance between the reported stations is
opposed to the identity of the two species, the known forms having almost always
very limited ranges

the leaves are smallerand their apical glands less developed, the union of the petiole
and the lamina forms a small, infundibuliform groove, on the margins of which the
petiolar glands stand, and the capsules are smaller with a shorter polar axis.

PREFACE.

The accompanying paper by Mr. Henry Pittier, of the United
States Department of Agriculture, contains descriptions of some new
species and other noteworthy plants, selected from several collections
which have recently come into the possession of the United States
National Museum. These collections form a most valuable addition
to the herbarium, and their richness in new and rare species
emphasizes the need of still further field work in tropical America
and the more extensive study of the plants already collected.

NEW OR NOTEWORTHY PLANTS FROM COLOMBIA AND
CENTRAL AMERICA.

By Henry Pirrier.

The present paper includes descriptions of a few plants from collec-
tions made mainly in the course of my explorations in Costa Rica
from 1887 to 1903, and of others obtained more recently in Guatemala
and Colombia in connection with investigations conducted on behalf
of the United States Department of Agriculture.

The two species from Colombia, Roupala ferruginea and Phyllan-
thus salviaefolius, are old, but have remained little known; addi-
tional specimens permit several interesting facts to be added to the
original descriptions by Kunth. The discovery in Costa Rica of two
new species of Phyllonoma bridges a gap in the geographical distri-
bution of a genus which has hitherto appeared widely interrupted, as
its previously known members came from Peru and Colombia on the one
side and from central Mexico on the other. The three Costa Rican
species of Carpotroche show the extension toward the west and north
of a genus thus far considered almost exclusively Brazilian. The
remaining species, besides being new, have several interesting features
which are noted in connection with the descriptions. JI am greatly
indebted to Dr. Th. Loesener, of the Berlin Royal Herbarium, for
his help in the identification of Myginda eucymosa.

Roupala ferruginea H. B. K. Nov. Gen. & Sp. 2: 153. pl. 120. 1817.

A small tree, with alternate limbs, the younger branchlets, petioles, main and
secondary veins, peduncles and pedicels ferruginose-tomentose.

Leaves alternate, petiolate; petioles rather thick, 1 cm. long; leaf-blade firm,
rounded at base, ovate, more or less acute, pale green and subglabrous above, brownish
white and delicately reticulate-venose beneath.

Racemes axillary, pedicellate, the pedicels 3 mm. long, adnate at base. Perianth
7 to8 mm. long, glabrous outside, longitudinally striate. Stamens glabrous; filaments
5 mm. long, flattened, adhering to sepals; anthers ovate-elliptic, about 2 mm. long;
end of connective rounded, scarcely surpassing the anthers. Pollen grains about
0.027 mm. in diameter, tetrahedral with a round nucleus. Glandular appendages
at base of pistil glabrous, square at tip; pistil 7 mm. long; ovary ovate, hairy;
style claviform.

The leaves of these specimens are uniformly rounded at the base and ovate and
more or less acute at the tip, while those of the type are described as **obovato-
oblongis basi angustatis.’’ Moreover the racemes appear to be single and not
geminate. But these small differences would not, apparently, justify the separation
of the Jambal6 form as a new species.

Phyllonoma tenuidens Pittier, sp. nov. Figure 11.
A bushy tree, 2 to 3 meters high, with erect, glabrous limbs and branchlets. Older
branchlets longitudinally striped with brownish white, irregular bands apparently
due to the splitting of the dark brown bark.
Foliage very dense. Leaves alternate, exstipulate, glabrous: petioles canaliculate,
slender, 7 to 10 mm. long. Leaf blades 5 to 7 cm. long, 2 to 3 em. broad, elliptic,
cuneate, long-acuminate, rather thin, discolorous: primary vein prominent under-

peduncles. Bracts at base of pedicels broadly ovate and subulate. Pedicels of
mature flowers pubescent, seldom over 1.4 mm. long. Prefloration valvate.

Flowers very small. Sepals glabrous, broadly triangular, about 0.5 mm. long,
with one minute tooth on each side. Petals 1.4 mm. long, 1 mm. broad, lanceolate-
acuminate, yellow. Stamens 1 to 1.2 mm. long, filaments broader at base: cells of
the anthers ovate, full. Hornlike styles about 0.5 mm. long.

Usually a single, small, pedicellate berry at each inflorescence, the diameter about
4.5 mm., the length 5.5 mm. Seeds usually 5 in each berry, ovate or ovate-elongate,
about 1.5 to 2 mm. long, reddish brown, densely covered with conical tubercles.

Costa Rica: La Palma, in the Central Cordillera, altitude 1,500 meters, H. Pittier,
flowers and fruits, October, 1902 (Instituto ffs.-geog. Costa Rica no. 16553; type
U.S. National Herbarium no. 578054).

The type of the genus is Phyllonoma ruseifolia Willd., a species from Peru, elabo-
rately described and figured by Kunth” under the name of Dulongia acuminata, In
1858, Turezaninow published two species; one, collected by Galeotti (no. 7197) in
the forests of Oaxaca, Mexico, at an altitude of 1,700 to 2,000 meters, he named Dilongia
laticuspis; the other, a native of the mountains of Pamplona in the Colombian Depart-
ment of Santander, whence it was brought by Funk and Schlim (no. 1657), is his
D. wntegerrima.

The first species differs from the type mainly by the indentation of the margin, which
begins near the base, instead of being limited to the upper third, and also by its
acumen ‘‘articulate on the blade, and parted to the main nerve.’’ In the U.38.
National Herbarium there is a species brought from around Teponapa, in the moun-
tains near Papalo (State of Oaxaca, Mexico), where it grows at an altitude of 500
meters above sea level (collected by Gonzalez and Conzatti, no. 764), that agrees
with Turezaninow’s description as to the indentation of the leaf, but does not show
any distinctive character in its long and acutely pointed tips. It differs also from
P. ruscifolia in having the inflorescences affixed at the base of the acumen, and not
on the blade proper; the marginal teeth, moreover, instead of being broad and short,
as shown in the H. B. K. plate, are narrow and finely mucronate. In all probability
these specimens correspond to Dilongia laticuspis Turcz.

Dulongia integerrima Turcz. differs from Willdnenow’s species by its leaves being
periectly entire, twice as large, and one-half as broad as in that species; the stigmas,
also, are said to be supported by very short styles. Dr. Britton referred to this species
Rusby’s no. 2521 collected at Mapiri, Bolivia. In the specimen of this collection at
hand almost every leaf bears a few irregularly placed teeth: they are larger, but never
twice as large, and decidedly not one-half broader (if a little so), as in D. laticuspis.
In the only flower that was available for study, there were 3 stigmas, this being with-
- out doubt an anomaly, but they were just as sessile as in D. acuminata and D. lati-
cuspis, Taking into consideration, also, the wide distance that separates the two
localities where the specimens were collected, I feel inclined to consider Rusby’s
plant a distinct species; but I must refrain from describing it as such, on account
of the insufficiency of material at hand.

Following the law of priority, the name Dulongia was dropped and Phyllonoma
maintained by Bentham and Hooker. - Also the genus was transferred from the Celas-
traceae, where it had been placed by Kunth, to the Saxifragaceae, to which it belongs
by a majority of its structural characters.

Dr. Engler@ admits only two species, viz, P. ruscifolia Willd., of New Granada
(Colombia), which he characterizes by its entire leaves and longer pedicellate flowers,
and P. laticuspis (Turez.) Engler with serrate leaves and short-pedicellate flowers,
from the high mountains of Mexico. This evidently leaves out the species of the
Nova Genera et Species, minutely described by Kunth, apparently from the same
specimens as those on which Willdenow established h's species. Should this view
be maintained, there would now be the following species: 7. ruscifolia Willd.=P,
( Dulongia) integerrma Turcz., with entire leaves; 1’. laticuspis (Turcz.) Engler, serrate
on almost the whole margin of the leat; ?. (Dulongia) acuminata H. B. K., serrate on
the upper half of the leaf only; Rusby’s species with subentire leaves; and lastly the
two Costa Rican species here described, that differ from all the others more than these
among themselves. On account of the scarcity of material in the European and
American collections, the true status of the doubtful forms can scarcely be determined
at present.

A small tree about 3 meters high, with numerous, alternate, tortuose, almost. hori-
zontal limbsand a depressed crown. Pseudo-branchlets 15 to 25 cm. long, caducous,
obscurely 4-angled, covered, like the ends of the permanent branches, with dense,
furfuraceous, brownish hairs, and provided at the base with 3 ovate, acute, stipule-
like scales.

Leaves alternate or distichous, petiolate, with narrow, pointed stipules, 6 to 7 mm.
long; petioles short (4 to5mm.), hairy; leaf blades 4 to8 cm. long, 2 to3cm. broad,
ovate-oblong, rounded or subcordate at base, narrowing gradually to an acute tip,
densely furfuraceous beneath, more or less smooth above except on main nerves;
primary and secondary veins hirsute and very apparent on both sides, the latter
regularly alternate, arcuate and parallel.

Flowers diclinous, forming short-pedunculate, compound corymbs in the axils of
leaves, each secondary cluster made up of I, 2, or more pistillate flowers, accompanied
by | to 3 staminate flowers, all together surrounded at base of pedicels by an involucre
of generally 4, lanceolate, hirsute bracts, the larger of which are about 5 mm. long.

Staminate flowers small; pedicels glabrous, 3 to 5mm. long. Sepals 6 in two alter-
nate circles of 3, each 1.5 mm. long, | mm. broad, ovate-oblong, with slightly narrower
claw. Disk cupuliform, plicate; stamens 3 to 9; filaments connate at base in a cylin-
drical column 0.5 mm. long, then free and unequal; connective broadened; anthers
bilocular, each cell opening longitudinally.

Bitoncd, in Moras Valley, in the Central Cordillera of Colombia, at an altitude of

Herbarium nos. 531520 and 531521). It grows in clusters around houses and if not
semicultivated is at least tolerated on account of its uses.

General distribution, Andes of Ecuador, Colombia, and Venezuela.

Local names, tefidero; Paez language, Sal.

Although this interesting species has been thoroughly described by several authors
besides the original, I venture here to give a new description based on the specimens
mentioned above, except for the characters of the seeds,-which I have not seen.

This plant, along with the several species of Castilla, belongs to that imperfectly
known series of tropical trees which, besides the usual ramification, bear other append-
ages that come midway between a branchlet and a leaf, and that may be called either
pseudo-branchlets or pseudo-leaves. Asa matter of fact they are more like compound
leaves, and in Phyllanthus salviacfolius they even show at their base stipule-like
scales; to make the likeness greater it may be added that they are shed once a year,
like the true leaves in deciduous trees, But on the other hand, their insertion on the
limbs of the tree seems to be more tike the insertion of a true branchlet, and in the
axils of their leaflets they bear the inflorescences, thus playing the role of true branch-
lets. This peculiarity seems to have been first observed on the Castilloa of the Isthmus
of Panama, by Robert Cross, who claims to have noticed the same phenomenon on
several other tropical trees. It would be interesting to make a list of these and on
that account the attention of future collectors is called to that striking feature of
tropical vegetation.

As the styles are usually trifid, only occasionally bifid, and very seldom quadrifid,
Phyllanthus salviaefolius should perhaps not come under Series I], but under Series I,
in the systematic arrangement as given by Pax in the Pflanzenfamilien.6 More-
over, the dehiscence of the anther cells is not transverse, but clearly longitudinal, as
already stated by Bonpland and Kunth.

The Paez Indians, in the mountainous valleys surrounding the Paéramo de Moras,
in the Central Cordillera of Colombia, use the decoction of the leaves to dye the wool
of their sheep, which they use for their clothing. The black color thus obtained is
said to be firm and lasting.

Myginda eucymosa Loesener & Pittier, sp. nov. Pirate XVIII.

A small tree 2 to’5 meters high, with dichotomous, erect ramification. Flowering
branchlets slender, flattened at the ends, glabrous.

Leaves petiolate, glabrous, opposite, each pair set at right angles with the adjoining
pairs. Petioles about 5 mm. long, canaliculate. Leaf blades 4.5 to 7.5 em. long, 2 to
4 cm. broad, elliptic-ovate to ovate-oblong, broadly cuneate, acuminate, dark green
above, paler beneath; main and secondary veins slightly prominent on lower face;
margin obscurely revolute, obsoletely serrulate with very minute, caducous, appressed,
nigrescent teeth.

Inflorescence distinctly cymose and profusely ramified, solitary, axillary, and not
quite as long as the leaves or much shorter. Bracts narrow and acute, opposite,

opposite pairs, orbicular, | mm. long, hairy outside. Petals obovate, 2 to 2.5 mm.
long, 1.6 mm. broad, attenuate into a short claw. Disk cupuliform, thick, divided
into 4 segments. Stamens | mm. long, alternate with the segments of the disk; fila-
ments slender, erect; anthers subreniform, of a deep orange-red color, Pistil glabrous;

This new species is intermediate between M. uragoga Jacq. and M. gaumeri Loesener.
It is somewhat like the first in habit, but differs obviously from it by being almost
entirely glabrous and in having larger leaves and more developed inflorescences.
From MM. gaumeri it is easily distinguished by its elongate, smooth branchlets, obovate
petals, and bifid style.

Costa Rica: Along roads on the peninsula of Nicoya, Tonduz, flowers, April,
1900 (Instituto fis.-geog. Costa Rica no. 13891; type U. 8. National Herbarium no.
472375).

This species differs from H. setulifera (Miers) Hemsl., with which it was associated
by Mr. Donnell Smith, in having its floral branchlets generally opposite, the leaves

much narrower, and the peduncles longer, and in other minor characters.

Carpotroche Endl.

There are here to be described three new Costa Rican species of this genus, the
hitherto known species of which are confined to the eastern part of tropical South
America. Of the new species one ((. platyptera), at least, is rather common in the
shady, damp forests of the Atlantic plains and lower hills of Costa Rica, and will doubt-
less be found also in Panama and in the zone of permanent rains in the northern part
of Colombia. No reason can be assigned why these interesting trees have so long
escaped the attention of botanists, unless it be the difficulty of collecting them, on
account of their large, bunched leaves, all crowded toward the ends of the branchlets.

The genus Carpotroche was based by Endlicher¢ on Mayna_ brasiliensis Raddi.®
Mayna itself is an obscure genus, incompletely defined by Aublet, and Zuccarini ¢
had already stated that Raddi’s plant, which he carefully described, had been wrongly
included in it and should form a genus by itself, mainly differing by its winged fruits,
but also by a few floral characters.

Endlicher’s elaborate description of the new genus founded by him at Zuccarini’s
suggestion was modified by Bentham & Hooker on account of the introduction of
several new species, also detached from Mayna. In 1845, Poeppig and Endlicher ¢
described and figured their C. ( Mayna) longifolia (Poepp.) Benth., the first known of
the truly dieecious species of the genus. In his revision of the genus in 1861, Bentham
transferred this last species from Mayna into its right place, included the new C. gran-
diflora Spruce, but ignored C. amazonica Mart., the description of which was published
ior the first time in 1871.¢ These additions caused important changes to be made in
Bentham & Hooker’s/ definition of the genus, and this was further modified, although
not in its essential parts, by Warburg.g The further addition of the three new Costa
Rican species makes it necessary to introduce again a few minor changes. The follow-
ing definition including these amendments will cover every one of the 7 species at
present known:

Flowers unisexual, seldom polygamous. Prefloration imbricate. Sepals 2 or 3,
persistent. Petals 4 to 12, in two rows. Staminate flowers numerous. lacking even
the rudiments of a pistil. Stamens hairy, inserted on a scarcely thickened torus;
filaments short; anthers linear, 2-celled, free or connected at base, opening in a longi-
tudinal slit. Pistillate flowers solitary, often larger than the staminate, lacking any
rudiments of stamens. Ovary superior, l-celled, with 4 to 8 carpels and an equal
number of parietal placentas, provided outside with twice as many longitudinal
wings. Styles 4 to 8, short, persistent, with scarcely capitellate stigmas. Ovules
numerous, anatropous. Fruit a large coriaceous or ligneous capsule, indehiscent,
ovate or rounded, provided with large, slightly undulated wings and crowned at the
end with the persistent styles. Seeds numerous, irregularly obovate, immersed in a
fleshy pulp that originates in the aril-like outer layer of the seed envelope, smooth

always single.

The seven species known to-day can be distinguished by means of the following key,
the imperfection of which is unadvoidable, owing to the incomplete knowledge of
these plants:

PREFACE.

The accompanying paper by A. S. Hitchcock, Systematic Agrostol-
ogist of the United States Department of Agriculture, entitled Cata-
logue of the Grasses of Cuba, is the result of an exhaustive study of
the material in the United States National Herbarium and in the
herbarium of the Estacién Central Agronémica de Cuba. It was
chiefly through the efforts of Mr. Carl F. Baker, who obtained large
collections in Cuba, that the specimens were made accessible to Mr.
Hitchcock. It is hoped that this paper will be followed by similar
ones upon other groups.

CATALOGUE OF THE GRASSES OF CUBA.

By A. 5. Hirencocx.

INTRODUCTION.

The following list of Cuban grasses is based primarily upon the
collections at the Estacién Central Agronémica de Cuba, situated at
Santiago de las Vegas, a suburb of Habana. The herbarium includes
the collections made by the members of the staff, particularly Mr.
C. F. Baker, formerly head of the department of botany, and also the
Sauvalle Herbarium deposited by the Habana Academy of Sciences.
These specimens were examined by the writer during a short stay
upon the island in the spring of 1906, and were later kindly loaned by
the station authorities for a more critical study at Washington. The
Sauvalle Herbarium contains a fairly complete set of the grasses col-
lected by Charles Wright, the most important collection thus far
obtained from Cuba. In addition to the collections at the Cuba
Experiment Station, the National Herbarium furnished important
material for study, including collections made by A. H. Curtiss,
W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M.
Tracy, Brother Leon (De la Salle College, Habana), and the writer.

The earlier collections of Wright were sent to Grisebach for study.
These were reported upon by Grisebach in his work entitled “Cata-
logus Plantarum Cubensium,”’ published in 1866, though preliminary
reports appeared earlier in the two parts of Plantae Wrightianae.¢
During the spring of 1907 I had the opportunity of examining the
grasses in the herbarium of Grisebach in Géttingen.’ In the present
article I have, with few exceptions, accounted for the grasses listed by
Grisebach in his catalogue of Cuban plants, and have appended a list of
these with references to the pages in the body of this article upon
which the species are considered. The numbers upon the labels of
the Wright specimens in the Grisebach Herbarium are in many cases
not the same as those under which the species were afterwards dis-
tributed and under which they were listed in the catalogue. These
numbers I have designated as secondary numbers. Grisebach has
sometimes connected on his labels the secondary number by the sign

of equality with the distribution number. The data upon the Grise-
bach labels are meager, usually consisting of the number and year,
together with an abbreviation for eastern or western Cuba. The
distribution numbers of the grasses reported upon by Grisebach are
all below 3500. Wright, after his return from Cuba, studied his col-
lections at the Gray Herbarium and published his results in a series
of articles in conjunction with Doctor Sauvalle, of Cuba.* In the

Volumes V to IX, 1868 to 1872. This was reset and, an index being added, pub-
lished in 1873 as Flora Cubana. The introduction to the first installment of the
series (5: 196. 1868) is as follows: ‘‘Revisio Catalogi Grisebachiani vel index planta-
rum cubensium ad catalogum Cl. Grisebachii anno 1866 editum attemperata, pluribus

adjectis cubensibus vulgo receptis a Francisco A. Sauvalle. Setiembre, 1868.”

HITCHCOCK—-GRASSES OF CUBA. 185

present paper the new species published in Sauvalle’s article are
credited to Wright. The original set upon which Sauvalle’s list is
based is at the Gray Herbarium, and a fairly complete duplicate set
is in the Sauvalle Herbarium.

The sets of Wright’s plants were made up at the Gray Herbarium
and given herbarium distribution numbers. Each number included
such collections as were thought to be of the same species. Thus it
often occurs.that different specimens of the same distribution num-
ber may have been collected in different localities or may even belong
to different species. The data found upon the field labels in various
herbaria are mentioned under each species in the present list. There
is also appended a list of the species of grasses included in Sauvalle’s
Flora Cubana, with references to their identification, and a list of the
Wright numbers in sequence with their identification.

The plan followed in the present paper is to give under specimens
cited a list of the specimens found in the herbarium of the Estacién
Central Agronémica, including the Sauvalle Herbarium, and in the
National Herbarium, without statement as to the herbarium in which
they are deposited. To these are added specimens found in the Gray
Herbarium which do not occur in the herbaria just mentioned, and
finally, specimens in the Herbarium of the New York Botanical
Garden (Herb. N. Y. Bot. Gard.), including the herbarium of Colum-
bia University, of which the Torrey Herbarium forms a part, which
are not found in the others mentioned. The specimens collected by
the staff of the botanical department of the Cuba Experiment Station
are numbered in a single series and are indicated in this list by the
letters HC (Herbarium Cubae). The data for the Wright specimens,
given in the paragraph devoted to the enumeration of specimens, are
understood to be found with the specimens in the Sauvalle Her-
barium. Additional data, found with specimens in other herbaria,
are quoted in the succeeding paragraph devoted to notes.

Grisebach enumerated 154 species of grasses in Ins catalogue.
Sauvalle’s Flora Cubana includes 170 species. The present list
includes 228 species or well-marked subspecies. |

KEY TO THE GENERA.’

Serres PANICEAE.—Spikelets 1-flowered, rarely 2-flowered; when 2-flowered the
terminal floret perfect, the lower staminate or neutral (except in Isachne), no apparent
tinternode between them; rachilla articulated below the glumes, the spikelets falling
from the pedicels entire, singly, in groups, or together with joints of an articulate
rachis; spikelets not laterally compressed (except in Lithachne).

Lemma and palea (the latter sometimes wanting in Andropogoneae) hyaline; glumes
more or less indurated, the first largest; sterile lemma like fertile lemma in texture

(except in Alloteropsis).

aJn this key the tribal characters are given with reference to the Cuban genera
only, and in some cases would not hold good for the entire tribe.

The type in the Trinius Herbarium is from Serra da Lapa, Brazil, though Trinius
in the original publication cites merely ‘“‘V. spp. Brazil.’ J. caudata Trin., as
shown by the type in the Trinius Herbarium, differs in having smaller spikelets
(about 2.5 mm. long), longer and more copious hairs, and an elongated inflores-
cence. The spikelets of J. brasiliensis are 4 mm. long. Wright’s specimen (3486)
is the latter species as shown by the specimen in the herbarium of Grisebach and
in that of Sauvalle. This is referred to I. caudata by Grisebach@ and Sauvalle.b

Wright’s 770 from eastern Cuba (1859) is A. bicornis as shown by the specimen in
Grisebach’s herbarium.

Wright’s 1555 as distributed consists in part of Andropogon bicornis and in part of
A.glomeratus. The latter is distinguished by the long-awned spikelets.

The Wright specimen in the National Herbarium bears a blank label of 1865. No.
1558 in the Grisebach Herbarium is from eastern Cuba, 1859, but the plant is
A. tener (there has probably been some misplacement of labels here). In the latter her-
barium is a specimen from western Cuba, 1863, with the secondary number 925,
upon which Grisebach has marked ‘“*=1558.’? One sheet of Wright 1558 in the Gray

This species is named for Mr. George V. Nash, who, while studying the species of
Andropogon in the National Herbarium, suggested that the above-mentioned speci-
mens did not belong to A. leucostachys, to which they had been referred. The species
is allied to A. leucostachys H. B. K. and A. subtenuis Nash.

apply to A. phragmitoides and to A. peruviana. Nees further states that the leaves
are smooth and one-half inch wide, and the panicle over a foot long and 4 inches
thick. This applies best to A. phragmitoides, though the blades are usually more
or less pilose. Specimens in the National Herbarium are as follows: Mexico: Lieb-

The Grisebach specimen is from eastern Cuba in 1860 and numbered 113=3478.”
Wright’s 3478 in the Gray Herbarium is from San Juan de Buenavista, Nov. 21.
These were compared with the type of Nees at Munich and that of Trinius at St.
Petersburg (from Martinique, Sieber 262). This species has an elongated dense panicle,
more or less folded blades, the bent awn twisted below. It ranges from Cuba and
Mexico to Brazil, and is represented in the National Herbarium by the following:
Porto Rico: Heller 934, 4355, 6256; Sintenis 361, 5797; Barrett 101. Santo Domingo:
Wright, Parry & Brummel 626. Jamaica: Eggers 3514. Mexico: Palmer 434, Costa
Rica: Pittier 11005; Tonduz 3672. Brazil: Glaziow 17433; Regnell 1414 (IIT).

Thysanachne scoparia Presl was published in the Symbolae Botanicae, the title
page date of which is 1882 and which, hence, is later than the Reliquiae Haenkeanac.
But the part containing the above species must have been published earlier, for in
the latter work@ is cited ‘7. seoparia. Presl de thysanachne, 1829. cum icone.”
There appears to be no such work by Presl except the portion of the Symbolae (pages
1] and 12 and:pl. 6) where Thysanachne and 7’. scoparia are described as if they were
there originally published. The species is based on Sieber 264 from Martinique.
Presl’s type from Mexico was examined at Prague. .

Pilger? refers the Porto Rico species to A. hispida (Willd.) Kuntze (Andropogon
hispidus Willd.), to which he also refers 1. brasiliensis Raddi. I have not seen the
type of either of the last two species, but in Trinius’s herbarium is the type of Gold-
bachia mikani Trin., which is included by Pilger in the list of synonyris of 1. hispida,
This I consider distinct from A. pallida, as did Nees, and it is what I take to be
A. brasiliensis Raddi. This is also the A. brasiliensis of Hackelin Martius’s Flora Bra-
siliensis, as indicated by plate 38 and by specimens so named received from Professor
Hackel. The spikelets are smaller and the awn shorter, sometimes scarcely exserted.
This species is represented in the National Herbarium by the following: Mexico:
Liebmann 622, 635. Colombia: Pittier 1527. British Guiana: Mount Roraima Exped.

Sheaths and blades pilose, the latter narrow and more or less folded, usually less
than 0.5 em. wide; panicle rather loose, not elongated as in A. martinicensis; awn
slender and bowed back like a shepherd’s crook, but not twisted. The type of
A. cubensis from eastern Cuba, no. 1552 in 1859, is in the Grisebach Herbarium.

18. REIMAROCHLOA gen. nov.

Spikelets lanceolate, acuminate, solitary, subsessile along one side of a flattened
narrow rachis (the back of the fertile lemma turned toward it), forming few to several
slender racemes, approximate at the summit of the culm, spreading or reflexed at
maturity; glumes obsolete except in the terminal spikelet in which one glume is
frequently present; sterile lemma exceeding the fruit; fertile lemma scarcely indu-
rated, faintly nerved, long-acuminate, inrolled at the base only, the palea of similar
texture, free nearly half its length.

Perennials of the tropics and subtropics of the Western Hemisphere.

The genus Reimaria as established by lliigge on the single differentiating character
“uniglumis,’’ included three species, the first two of which, R. candida and R: elegans,
differ from Paspalum only in having spikelets without glumes, a character which is
unreliable in this group of Paniceae. The third species, R. acufa, together with
those added to Reimaria by later authors, constitutes a distinct genus distinguished
by the characters in the diagnosis above. Considering that Fliigge’s three spe-
cies are not congencric, but that the first two on the one hand and the third on the
other must be separated, it is necessary that the name Reimaria go with the larger
group.° Reimaria then becomes a synonym of Paspalum, or if the glumeless species,
P. candidum UW. B. K., P. pulchellum IL. B. K., P. elongatum Griseb., etce., be con-
sidered generically distinct, the name would apply to this group. For R. acuta and its

This resembles P. papillosum Spreng., but the spikes are usually solitary instead
of in pairs and the spikelets obovate instead of orbicular. The type of this is in the
Gray Herbarium. The plant in the Sauvalle Herbarium under this number is a
different species, as are the two specimens in the Grisebach Herbarium which are said
to be ““=3444” (cf. P. caespitosum and P. rupestre of this list), Salzmann’s specimen
in Trinius’s herbarium from Bahia, labeled Paspalum horticola Salzm., belongs to
this species. Salzmann’s name was mentioned as a synonym by Steudel under

Doell © refers P. filiforme Sw. to P. caespitosum Fligge. This is not the plant that
Swartz describes, as is shown by the original description in the Prodromus and the
later amplified description in his Flora.’ Swartz describes his plant as having a

15. Paspalum lineare Trin. Gram, Pan. 99. 1826.

Herradura, Baker 3459; Isle of Pines, Curtiss 379.

The type in the Trinius Herbarium is from Brazil, collected by Langsdorff, and is
included in the same cover with P. angustifolium Nees. Trinius published the latter
name on the same page of the work cited, but preceding P. lineare on the page. The
type is said to be from ‘‘Brazil (N. ab Esenb.).” The type specimen is labeled
“Paspalum angustifolium N. ab Es. In Brasilia. Mis Auctore.” This specimen,
however, is not P. lineare, but has, as described, smaller spikelets with rugose trans-
versely wrinkled glumes. P. angustifolium as described three years later? is the
same as P. lineare Trin., while variety / is P. angustifolium as described by Trinius.
Consequently P. neesii Kunth is a typonym of P. angustifolium, since Kunth changes
the name of the latter on account of the earlier P. angustifolium Le Conte, but the
name does not apply to the Cuba plant under consideration.

type of P. caudicatum, in the Gray Herbarium.

the Grisebach Herbarium bears the label, ‘176. Bushy savannas. Hanabana,

Spikelets sent by Professor Le Comte” from the plant supposed to be the type of
Paspalum lindenianum Rich.» show this plant to be the same as P. nanum Wright,
but this species does not agree with Richard’s description in so far as the blades are
said to be glaucous and glabrous except the ciliate margins, while in P. nanum the
blades are pubescent on the surface, Pending a further examination of the type the
name P. nanum is retained.

I have not seen the type of this species, but in the Trinius Herbarium there is a
specimen labeled ‘Paspalum papillosum Sprengel, mis. cl. auctor.’”? The Cuban
plants agree with this, except that the spikelets are less glandular, the flat surface
being quite glabrous. Agreeing with Sprengel’s specimen are two in the Trinius
Herbarium, one collected by Salzmann in Bahia labeled ‘‘ Paspalum horticola.meri-
tima Salzm.’’ and another by Riedel at Bahia in 1831. Tonduz’s 4474 from Costa Rica

This agrees with Asiatic specimens and may be introduced. It differs from
FE. punctata in the narrower blades and the shorter awn to the fruit.

Allied to these is the Porto Rican Eriochloa subglabra (Nash). (Monachne
subglabra Nash, Bull. Torr. Club 30: 374. 1903; Eriochloa punctata subglabra Urban,
Symb. Antill. 4: 85. 1903). This species differs from £. ramosa in the broader
blades and pronouncedly velvety nodes, and in habit; from #. punctata in the
mucronate, instead of slender-awned, fertile lemma, and from both in having a
staminate flower in the axil of the sterile lemma. Urban reduced this to a variety
of £. punctata without having seen the plant.

Wright 1544 in part.

The specimen of Wright’s 1544 in the National Herbarium labeled, ‘“‘Sandy pine
woods, Pinar del Rio, Sept.,’’ is partly this and partly 8. leucocoma Nash. Hackel «
bases his P. curvinerve upon this portion of Wright 1544. The characters which he
mentions, such as the smooth glumes with incurving nerves, are found not infrequently
among specimens of S. filiformis from the northern United States, whence the type
was collected by Kalm. In the specimen of 1544in the National Herbarium (the
smaller portion with spikelets only 1.5 mm. long) part of the panicles have nearly
glabrous spikelets, and part have long-pubescent spikelets. This differs distinctly
from the other part of Wright 1544, which Hackel may have taken for the true
S. filiformis. The amount of pubescence upon the spikelet is quite variable in this
species as in othersofthisgenus. Thesize of the spikelets, however, is fairly constant.
In the Grisebach Herbarium there are two specimens of this from eastern Cuba, one
collected in 1859 numbered 1544, the other in 1860 numbered ‘‘107=1544.”’

« The type species is A. distachya Presl (op. cit. 344), which is published as coming
from Monterey, California, but the type in the National Museum at Prague has two
labels, ‘Peruana montana,” and ‘‘Regio montana Luzon?’’ The plant is Allote-
ropsis semialata (R. Br.); Panicum sem ialatum R. Br. Prod. 192. 1810, the type of
which is from New Holland. This is not an American species and Presl’s type must
have come from the Philippines, as indicated by Scribner (Rep. Mo. Bot. Gard.
10: 37. 1899). Presl’s plate and description are incorrect in that the artist incor-
porated in the drawing of the spikelet of Alloteropsis a spikelet of an Andropogon
which had become wedged between the glumes and this is described as a second
pairof spikelets. Although Presl’s genus is founded upon a misconception there is no
doubt as to the identity of the type species. Hence Alloteropsis, the oldest name
for this group as segregated from Panicum, is accepted for the genus.

rium. The fragmentary Specimen in the Sauvalle Herbarium bears the label

aMesosetum Steud. Flora 33: 228. 1850, nomen nudum. The type species of
Mesosetum is M. cayennense Steud... **Leprieur legit. in Cayenne,’ the type speci-

but not hispid, and glumes and lemmas all notched near the apex, hence some-
what 3-lobed. In Sauvalle’s Flora Cubana Wright 3859 is doubtfully referred to

The first two specimens cited above are like the type at Munich; the others are
more or less pubescent, but appear to be otherwise the same. The type of Pani-
cum proliferum pilosum Griseb. in the Grisebach Herbarium is labeled ‘‘Around
lagunas in wet or damp ground, Hanabana, May 16,’ no. 186. This is the same
as Wright 3860 in the Sauvalle Herbarium. Probably P. bartowense Scribn. & Merr.4
is a form of P. chloroticum. It differs from the Brazilian specimen only in its hispid
sheaths and from some of the hispid Cuban specimens only in its larger size. Nash’s
567 from Eustis, Florida, is a low spreading form, with culm about 30 cm. long, but
the blades and sheaths pubescent like P. bartowense. P. dichotomiflorum Michx.
(P. proliferum of American authors, not Lam.), common throughout the eastern
United States, is smooth throughout, and is usually more or less geniculate-spreading
at base, and the blades are usually long and gradually acuminate. In Florida this
shows a tendency to become pubescent. Combs d& Rolfs 94 from Lake City, Florida,
has the habit of 2. dichotomiflorum, but the blades are pubescent on the upper sur-
face. The spikelets of P. dichofomiflorum vary in length from 2 to3 mm. It would
appear that there is one variable species, including P. dichotomiflorum Michx.,
P. chloroticum Nees, and P. bartowense Scribn, & Merr. The West Indian specimens
resemble more closely ?. chloroticum in habit, and for the present they are referred
to this species. Other specimens of the same in the National Herbarium are: Baha-
mas, Nassau, Curtiss 177; Cat Cay, Brace 3742. Bermuda: Hamilton, Millspaugh 126.
Porto Rico: Unado, Britton & Cowell 432. South America: Brazil, Riedel 959, Salz-
mann (P. hygrophilum Salzm.); Paraguay, Morong 1002; Uruguay, Arechavaleta.

Wright’s 3456 and 3861 cited above have larger spikelets than the other Cuban
specimens (3 mm. long), but this appears to be a variable character. Wright 3456
is the type of P. proliferum strictum Griseb.¢ Wright 3456 in the Gray Herbarium
is from ‘‘ Lagunas, Almacigos, Nov. 23.”’

The Grisebach specimen of Wright 3461 also belongs to this species, though it is
listed by him under P. dichotomum variety nodiflorum. Another specimen of this
was included by Grisebach under P. neuranthum; it is labeled ‘‘ a forma ascendens
ramosa.”? Wright’s 3461 in the Gray Herbarium is part P. chrysopsidifolium and
part P. lancearium. The two labels are, ‘‘Sandy pinales, Asiento Viejo de San
Julian, Dec. 1,’? and ‘* Pinal. Mayari, July 24.”

This species is distinguished from P. neuranthum by the pubescent culms, bearded
nodes, spreading vernal panicles, and short, flat autumnal blades on zigzag stems.
The spikelets are 2 mm. long. It occurs in Florida and in Porto Rico (Heller 982).

7. Panicum caerulescens Hack. in herb.

Vernal form cespitose, of a somewhat glaucous bluish green color; culms erect or as-

nodes, glabrous or the basal ones sparingly pubescent; blades ascending or spread-
ing, commonly purplish beneath, glabrous or rarely a few hairs around the base, 5 to
8 cm. long, 4 to 7 mm. wide, the margins nearly parallel for two-thirds their length;
panicles usually short-exserted, 3 to 7mm. long, one-half as wide or less, the branches
narrowly ascending; spikelets 1.5 to 1.6 mm. long, 0.9 mm. wide, obovoid, blunt,
very turgid, glabrous, first glume about one-third the length of the spikelet; second
glume and sterile lemma subequal, the glume scarcely as long as the fruit at maturity;
fruit 1.4 mm. long, 0.8 mm, wide, ellipsoid.

Autumnal form erect or leaning, sometimes decumbent at base, producing short,
densely fascicled branches at the middle and upper nodes, these tuits scarcely as long
as the primary internodes, the reduced blades ascending, more or less involute; the
reduced panicles with only a lew long-pediceled spikelets.

Closely related to P. roanokense, a species of the southern Atlantic coastal plain of
the United States, from which it is distinguished by the narrow panicles and smaller
spikelets and by the tufted branches of the autumnal form.

The type is Hitchcock 706, ‘In glade among Spartina, etc., stretching up through
the tall grass, Miami, Florida, April 3, 1906; U.S. National Herbarium no. 558380.
The name refers to the glaucous blue color.

form of P. divaricatum. The pubescent form can scarcely be separated even as a
variety.

Hamilton’s species is based on ‘‘P. bambusoides Herb. Prof. Desv. Porto Rico.’’ A

*927=3458.”’ This is listed by Grisebach > as P. cyanescens. The type of P. parvi-
folium is in the Lamarck Herbarium at Paris. Wright 3458 in the Gray Herbarium is
labeled ‘‘In lagunas (ponds) Los Almacigos, July 28,’’ and ‘‘On tembladeros in
lagunas, Asiento Viejo de San Julian, Nov.”

There is some material of this species mixed with Wright 3461 in the Krug and
Urban Herbarium. This species occurs also in Porto Rico (Heller & Heller 982b, 639,
Underwood & Griggs 955),and is common in the Atlantic coastal plain of the southern
United States.

There seems to be an error in the number of the Wright specimen. It is published
as 3451 in Grisebach’s catalogue and in Flora Cubana, and the specimen is so num-
bered in the Kew and the Grisebach herbaria, but in the Sauvalle and the Berlin
herbaria the number is 3457. The Grisebach spécimen is from western Cuba, 1863,
numbered *‘888=3451.”

The hairs on the rachis are variable. Curtiss’s 305 in the National Herbarium is
without hairs; the same number in the herbarium of the Cuba Experiment Station
has hairs on some of the spikes. Wright’s 3451 in the Gray Herbarium is from ‘‘ Retiro,
July 15, in woods (damp).’’

number has been found in no other herbarium. The fertile lemma is slightly over
2 mm. (2.2 mm.) long, and the margins do not meet except at the tip, thus exposing a
narrow strip of the palea. The scars at the base are small and the wings are wanting.

There are four specimens of this in the Grisebach Herbarium: No. 750 labeled
‘Prope villam Monte Verde dictam. Cuba orientali;”’ another numbered 750 from
eastern Cuba, 1856-57; a Wright. specimen without number or locality collected in
1860-64; and a specimen with proliferous spikelets, numbered 887, ‘‘Cuba occ. Wr.
1863.’? This species not infrequently occurs with proliferous spikelets, as in Palmer
“& Riley 130 cited above. The spikelets then consist of many sterile lemmas and
the plants appear as if belonging to the tribe Festuceae.

4. Ichnanthus wrightii sp. nov. .

Culms slender, prostrate-spreading, more or less rooting at the nodes, glabrous
or sparsely villous, 20 to 30 cm. long; sheaths mostly less than half the length of
the internodes, striate-nerved, villous on the margins, otherwise glabrous or nearly
so; blades ovate-lanceolate, striate-nerved, faintly 3 to 5-ribbed, glabrous, 12 to
30 mm. long, 2 to 8 mm. wide on the sterile shoots, somewhat larger and thicker
on the ascending flowering culms, all abruptly or cordately narrowed into a slender
stalk | to 5 mm. long on the fertile culms, or as much as 15 mm. long on the sterile
shoots; panicles 4 to 8 cm. long, consisting of a few spike-like racemes, 0.5 to 2 cm.
long; spikelets 3 mm. long, glabrous, the pedicel minutely pubescent; lower glume
about half the length of the spikelet, 3-nerved; second glume and sterile lemma
equal, acuminate, strongly 5-nerved; fertile lemma scarcely 2 mm. long, the edges
meeting and covering the palea, except at the very base, the outer margin of the
base of the lemma bearing a scar at each side, but no wings.

Wright’s 3880. U.S. National Herbarium no. 559959 of this collection is the type.
The specimen in the Sauvalle Herbarium is labeled, ‘‘Under overhanging rocks
(damp) and around base of palms beside the Rio Seco in Arroyo Honda, Pinar del
Rio, Dec.’? The Grisebach specimen consists of a single spikelet in a packet, labeled
“Echinolaena Sp.’’ no. 760. In the Kew Herbarium there are four specimens num-
bered 2, 23, 244, 760. Nos. 760 and 3880 are also in the Gray Herbarium. This
species is allied to 7. mayarensis.

Wright’s numbers 751 and 1543 in the Grisebach Herbarium are from eastern Cuba,
1859. The latter is numbered 1593 in Sauvalle’s Flora Cubana.

It is quite possible that the specimens here included may be referred to distinct
species. The type of Panicwm setaritum Lam. at Paris resembles Wright’s 1543. The
blades are short and the clusters of spikelets globose and few-flowered. Wright 751
and Curtiss 268 and 593 have larger and longer blades and spikes, but some of the
other specimens are intermediate.

15 to 20 cm. long. The bristles are only a little longer than the spikelets, the spikes
about | cm. long, the blades without the scattered long hairs on the upper surface
found in most of the specimens. 2. No. 200 of 1865, which Grisebach has labeled

The locality is not indicated except that the collection was made in eastern Cuba
in 1856-57. This is referred by Doell® to Panicum chaetium Steud. (Chaetium
festucoides Nees), but it differs in many respects. The blades are short and narrow,
mostly involute; the inflorescence is loose, the spikelets few and distant, narrowed to
a pedicel 1.5 mm. long, strongly bearded at the base; first glume very narrow, 22 mm.
long including awn, 3-nerved at base; second glume 5-nerved, 18 mm. long, including
awn; sterile lemma and fertile lemma thin, 3-nerved, awnless, 4.5 mm. long.

The Grisebach specimen, which is the type, bears the secondary number 207, and
was collected in 1865. This is listed in Sauvalle’s Flora Cubana as Chamaeraphis
parvigluma Munro, a nomen nudum, and the Wright number is misprinted 3909.
In the Gray Herbarium is a specimen of this species from Santarem, Pard, collected
by Spruce, which agrees with Curtiss 461 in being more pubescent than the Wright
specimen. This appears to be a duplicate type of Panicum leptochyrium Doell, though
the specimen is not numbered.

236 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

Cuba, 1856-57 in Sauvalle Herbarium; Jata Hills at Guanabacoa, Hitchcock in 1906;
Baker & Hasselbring HC 7208, 7211; Madruga, Britton & Shafer 658 in Herb. N. Y.
Bot. Gard.

There are two Wright specimens of this in the Grisebach Herbarium, ‘‘Savannas of
Guanacaro, July 28, in small tufts,’’ no. 282 of 1865, and no. 736 from eastern Cuba,
1856-57.

This species is readily recognized by its stiff, rush-like culms and short sharp-
pointed blades. On the Jata Hills it occurs on dry, grassy slopes.

2. Aristida erecta sp. nov.

Culms erect, rather stout, from a perennial root, about 1.5 meters high, glabrous;
sheaths glabrous, longer than the internodes; blades glabrous beneath, scabrous on
the nerves above, elongated, convolute, much attenuated at the tip, 3 to 5 mm. wide,
as much as 1 meter long; panicles 50 cm. long, the numerous scabrous branches ascend-
ing below, spreading above, the lower as much as 20 cm. long, all spikelet-bearing to
the base; spikelets crowded, the pedicels erect, stout, 2 to 3 mm. long, glumes gla-
brous, the first 12 to 15 mm. long, scabrous on the keel, abruptly cuspidate or awn-
tipped, 3-nerved, one of the lateral nerves somewhat indistinct, second glume 2 to 3
mm. shorter, acuminate, |-nerved, smooth on the keel, lemma 12 to 13 mm. long,
glabrous, the callus about | mm. long, bearded, awns spreading, the central 2 to 3
em. long, the lateral somewhat shorter.

The type specimen was collected by Wright in Cuba in 1865, no. 41161, in the U.8.
National Herbarium. This specimen is numbered in pencil 2432, which is an error
for 3432. The corresponding specimen in the Grisebach Herbarium was collected in
western Cuba in 1863 and is numbered ‘‘928=3432.’’ The only other specimen seen
is: Herradura, Tracy 9076.

This species resembles A. palustris (Chapm.) Vasey, but differs in having taller
culms, larger and more spreading panicles, and longer glumes and lemma. In A.
palustris the panicle is narrow and strict, the glumes are about 10 mm. long and nearly
equal, and the lemma is only 7 to 8 mm. long.

brown hairs, which extend upward along the margins of the blade for a short distance
basal blades very long and narrow, flat, or involute, nearly as long as the culms, 1 to 2
mm. wide, smooth except for the basal hairs, strongly striate-nerved, the two or three
upper blades short, 2 or 3 cm. long; panicle slender-pyramidal, glabrous throughout,
8 to 10 em. long, branches verticillate, lowermost 5 to 8 in a whorl, slender and stiffly
spreading, 1.5 to 3 cm. long; spikelets glabrous, tawny, 3.5 to 4 mm. long, appressed,

purpurascens. S. cubensis is distinguished from 8. purpurascens by its larger spikelets,
3.5 mm. long, the elongated blades, and the ferruginous-silky basal sheaths. Heller’s
4590 from Porto Rico is 8. cubensis. In the Grisebach Herbarium are three specimens
of this from Wright: No. 3427a of 1860-64; no. ‘'922=3422” from western Cuba, 1863,
and no. ‘'945=3422”’ from western Cuba, 1863. (No. 3422 as published in Grisebach’s
Catalogue, is Eragrostis sudans). It will be noted that nos. 3427 and 3427a are the
reverse of what they are in the Sauvalle Herbarium. Wright’s 3427 in the Gray Her-
barium is from ‘‘ High pine woods, pinales, Mar. 1;”’ another sheet of this number is
part S. cubensis and part S. purpurascens.

at Stockholm; the spikelets are2.5mm.long. Fournier noticed thedifference between
the two species (S. cubensis and 8. purpurascens) distributed by Wright under 3427,
but described as new the one already named. Wright 3427a in the Gray Herbarium
is from ‘‘savannas, Chirigote, July 11.”

The Grisebach specimen is no. 291 in 1865, ‘‘Seashore, Matanzas, July 8.’’ In
Sauvalle’s Flora Cubana this ‘is numbered 3830, which is probably correct, as the
specimen in the Gray Herbarium is also numbered 3830.

«There is some question as to the standing of Capriola as a genus, since it is based
upon “‘Gramen dactylon offic.”’ (Adans. Fam. 2:31 and 532. 1763.) But since
Linneus cites under Panicum dactylon ‘‘Gramen dactylon, radice repente, S. offi-

genus on this species, though he does not quote a definite author.

There are three Wright specimens of this species in the Grisebach Herbarium:
Nos. ‘‘917=1548” and ‘'932=1548” from western Cuba, 1863, and no. 1549 from
eastern Cuba, 1859. The type of C. brevigluma is in the Gray Herbarium with
printed label for 1860-64, no. 1548. In Sauvalle’s Flora Cubana the type is mis-
printed ‘‘1848 p. p.’’ Wright seems to have distinguished his species from C. eleu-
sinoides mounted on the same sheet (Wright 1549), which he regarded as the true
C. cruciata. Wright’s type matches his no. 1549 in the National Herbarium.

The Grisebach specimen is from eastern Cuba, 1859, no. 1548. Nos. 1548 and .
1549, in the Engelmann Herbarium, both from eastern Cuba, 1860, are Chloris
cleusinoides. No. 1549 in the Gray Herbarium is also this species (Monte Verde,
eastern Cuba in 1859).

Combs’s 631, from Cienfuegos, in the Gray Herbarium is the type of C. eleusinoides
variety vestita. It differs from Grisebach’s type in being somewhat more pubescent.

with that of a specimen of L. fascicularis. In the Gray Herbarium there are two sheets
numbered 741, of which one is L. filiformis from ‘Cultivated ground, Valestina, Nov.

The type of Festuca filiformis Lam. ‘‘ex Amer. merid. Comm. D. Richard” upon

the description is insufficient for identification. This name may be found to apply to
this species.

This has been confused with EF. bahiensis Steud., which is a larger plant, 60 cm.
or more tall. H. berteroiana (Schult.) Kunth, of Santo Domingo, has smaller spikelets
with lemmas scabrous on the keel, as shown by a specimen from Kunth in Trin-
ius’s herbarium. The Grisebach specimen from Wright is numbered ‘‘938=3424,”
and is from western Cuba, 1863, ‘‘bushy swamps, Hanabana, May 16.’’ Another

is from western Cuba, 1863, and is numbered 903. Wright’s 3424 in the Gray Her-
barium is from ‘‘savannas, Chirigote, July 13.”

This is described and figured by Sloane,¢ and is cited as a synonym by Swartz
under Poa glutinosa ® and by Grisebach;¢ but Poa glutinosa Sw. is Eragrostis sudans
Griseb., while Wullschlaegel’s specimen from Jamaica, cited by Grisebach under
Eragrostis glutinosa, is E. elliott S. Wats.

Pilger@ states that /. macropoda differs from £. nitida (Ell.) Chapm. in having
long-peduncled spikelets. However, the type of Poa nitida Ell. has long-peduncled
spikelets and is well matched by Wright 3423.

PREFACE.

The accompanying report by Dr. J. N. Rose is a continuation of his
Studies of Mexican and Central American Plants. It varies little in
style and treatment from the earlier numbers, of which five have
already been published. ‘They all emphasize the botanical richness of
the countries south of the United States, and the importance of careful

work by experienced collectors.

STUDIES OF MEXICAN AND CENTRAL AMERICAN
PLANTS—NO. 6."

By J. ». Rose.

INTRODUCTORY NOTES.

This paper consists largely of descriptions of new species found in
the process of naming large collections from Mexico, or in revising
various genera of Mexican plants. It forms the sixth of this series
and differs little, in its scope from previous ones. The collections
studied have been chiefly those mentioned in my last paper, together
with material received during the year 1906. A somewhat detailed
account of my sixth journey through Mexico will not be out of place
here.

On July 26 I was authorized by Dr. R. Rathbun, Assistant Secretary
in charge of the National Museum, to proceed to Mexico for the pur-
pose of continuing my botanical explorations there. By the kindness
of Dr. N. L. Britton, Director of the New York Botanical Garden,
who placed a generous sum from the Garden funds at my disposal, I
was enabled to take an assistant with me from Washington. I left
Washington August 1 accompanied by my son, Joseph S. Rose, for
the city of Mexico. En route for that city | made short stops at San
Antonio and Laredo, Texas, where small collections were obtained.
The City of Mexico was reached August 10, and for several days there-
after I was engaged in establishing suitable headquarters in that city.
Some time was also spent at the herbarium of the Instituto Medico
Nacional, where every facility was given to help me in my work. <A
short trip was also made during this time to the pedregal near Tlalpam,
where a number of cacti and ferns were obtained. In the city of
Mexico I was joined by Dr. C. G. Pringle and his assistant, Filemon
Lozano; who accompanied me on various side trips. From the City of
Mexico short trips were made to Cuernavaca, El Parque, Querétaro,
Pachuca, and various places in the valley of Mexico, including one for
water lilies to Lake Xochimileo. Toward the end of August I was
joined in the city of Mexico by Dr. D. T. MacDougal and soon after-
wards we changed our base to Tehuaciin, Puebla. Here we explored
the limestone hills on both sides of the town, making large collections

of herbarium specimens and selecting exhibition specimens of cacti,
which were shipped to the New York Botanical Garden. From Te-
huacan side trips were made along the tramway toward Esperanza and
to Oaxaca city, and from the latter point Mitla was visited, where two
days were spent in and about Tomellin Cafon. <A short trip was
made to Vera Cruz and also to Leon, after which I closed up my field
work and returned to Washington.

The herbarium material collected contains more than 500 numbers
(11001-11534), a full set of which has been mounted for the National
Herbarium. .

In addition to the herbarium material 236 specimens of seeds, bulbs,
and succulents (chiefly cacti) were collected and sent to Washington.
At the same time a nearly full set of the cacti was selected and
shipped to the New York Botanical Garden. Many of these latter
specimens were of immense size and form striking exhibition objects.

The following table will show in detail the places visited, the date
of each visit, and the number of miles traveled in course of this trip:

CYCADACEAE

A NEW SPECIES OF DIOON.

Dioon purpusii Rose, sp. noy.

Trunk short, crowned by numerous leaves, these often a meter or more long, stiff
and ascending; petioles somewhat 4-angled; pinnie 5 to 9 cm. long, stiff, pungent,
towards the base, 1 to 1.5 cm. apart, above closely set, entire on the lower margin,

but usually with 1, 2, or rarely 3 sharp spine-like teeth on the upper margin; male
cones 15 to 20 cm. long, the bracts with recurved ovate tips; female cones ovate, 44
cm. long by 20 em. broad near the base; bracts very woolly, 10 to 15 cm. long; seeds
about 4 cm. in diameter.

Collected by D. T. MacDougal and J. N. Rose, September 7, 1906, in Tomellfn
Cafion, Oaxaca (Rose 11352, type), and by C. A. Purpus in Sierra Mixteca, Puebla, in
1908.

Type U. 8. National Herbarium no. 454142.

The specimens found by MacDougal and Rose were in a deep canyon
well shaded by bushes and small trees. Both male and female cones
were taken and also a living plant. The latter is now growing in the
conservatory of the New York Botanical Garden, where also are pre-
served the cones. In 1908 Dr. Purpus collected seeds and bracts.

GNETACEAE.
A NEW SPECIES OF EPHEDRA.

I was much surprised to find an Ephedra on the desert plain about
Tehuacin, as none had been reported farther south than San Luis
Potosi. This one is so clearly distinct from those of northern Mexico
that I do not hesitate to describe it as new.

Ephedra compacta Rose, sp. nov.

A low very compact shrub, 30 to 50 em. high with many numerous short spines-
cent branches, at first light green but becoming very pale; leaves opposite, high-con-
nate; male flowers not seen; fruit scales in pairs, high-connate, when mature form-
ing a small red fleshy fruit; seeds 2.

Collected by J. N. Rose and J. 8S. Rose near Tehuaciin, September, 1906 (no. 11274,
type), and at same station by Rose and Painter, August and September, 1905 (no.
10023).

Type U.S. National Herbarium no. 454055.

Nearest F. pedunculata Engelm., but lower, of much more compact habit, and with
paler and less fluted stems. |

LILIACEAE.
A NEW SPECIES OF BEAUCARNEA.

Since publishing my enumeration of the species of Beaucarnea in
volume 10, page 87, of this publication, an additional species has been
sent me by Mr. E A. Goldman, of the Biological Survey, Department
of Agriculture, which is here described:

Beaucarnea goldmanii Rose, sp. nov. PuaTeE XX,

Tall slender tree with swollen base; leaves hanging, 80 to 90 cm. long, 3 em. broad
at the base, 1 to 1.5 em. broad a short distance above the base, tapering toward the
apex into a long acumination 20 to 30 cm. long, smooth on both surfaces, the margin
nearly or quite smooth; inflorescence a panicle 30 to 50 cm. long; pedicels 8 to 10 mm-
long, jointed near the middle; fruit somewhat glaucous, 18 to 20 mm. long, broadly
3-winged, notched at base and apex.

Collected by E. A. Goldman at San Vicente, Chiapas, April 26, 1904 (no, 887).

Type U. S. National Herbarium no. 566461.

262 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM,

This species resembles somewhat Bb. guateimalensis, but has the leaves larger and
the fruit narrower, glaucous, and less notched at apex.

EXPLANATION OF PLATE XX.—Two views of the type tree reproduced from photographs taken by
Mr. E. A.‘Goldman. These are here used through the courtesy of the Biological Survey of the
Department of Agriculture.

A NEW SPECIES OF BESCHORNERIA.«

Very little is known about the species of Beschorneria in Mexico
itself, although I believe the genus is endemic to that country. All
the species have been described from greenhouse material. In 1906
Dr. Pringle rediscovered 2. yuecordes in the mountains above Pachuca
and later in the season he took me tod the locality, where I collected
material both for the herbarium and for the greenhouse. While
studying this material I reached the conclusion that certain material
from San’ Luis Potosi, heretofore referred to 2. tub/fora, represents a
new species, and this is here described:

Beschorneria rigida Rose, sp. nov.

Leaves numerous, erect, rather rigid, 30 cm. long, 2 em. or less broad, narrowing
into a long acumination, roughened on both surfaces; inflorescence about a meter
long; bracts 15 to 20 em. long, large, purplish, each subtending 2 to 4 flowers; whole
flower 4.5 cm. long; perianth segments dull in color, usually greenish yellow, some-
what scabrous; stamens shorter than the segments; capsule oblong in outline, 3 cm.
long; seeds black.

The following specimens have been examined:

San Luis Potosi: Near Alvarez, Palmer & Parry, 1878 (no. 866); same station,
Dr. It. Palmer, May, 1905 (no. 598, type).
Guanajuato: Near San Felipe, Dr. G Baroetta, 1904 (Economic herbarium U.S.
Department of Agriculture).

The type is U. 8. National Herbarium no. 570098.

This has heretofore been taken for B. tubifiora, but a careful reading of the original
description of Furcraea tubiflora clearly excludes it. The leaves are narrower, erect,
rough on both surfaces, the flowers more numerous and duller in color.

Dr. G. Barroetta, of San Luis Potosi, reports that this species is a fiber plant.

RAFFLESIACEAE.
THE NORTH AMERICAN SPECIES OF PILOSTYLES.

The first species of Pilostyles found in North America was collected
by Dr. Geo, Thurber in L850 in southwestern Arizona. Between that
time and 1890 no additional species were found, but since the latter
date much material, embracing several new species, has been received
at the National Herbarium, especially from Mexico. Prof. Solms-
Laubach, who monographed the genus in 1901, recognized but two
species in North America.

The material now on hand contains 8 species, four of which are here
first described. All our American species are found on three genera
of Leguminosae.

aA. Berger has recently published another new species: Beschorneria pubescens
Berger, Monatsschr. Kakteenk. 17: 1. 1907.

The host is a Parosela, perhaps 2. canescens Rose,

264 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

Collected by Rose and Painter in two localities near Tehuacdin, Puebla, September
1905 (no. 8942). This species was very common, but collectors might easily over-
look it.

Type U. 8. National Herbarium no. 453435.

The flowers occur in great. masses on the lower parts of the stem and branches of
the host, often retarding its growth and doubtless eventually causing its death.

Pilostyles mexicana (Brandeg.) Rose.
Apodanthes mexicana Brandeg. Zoe 5: 244. 1908.
Host Calliandra grandiflora Benth.

Pilostyles palmeri Rose, sp. nov. FIGurE 22,

Somewhat similar to P. glomerata, but flowers smaller (2 mm. long), the bracts
and sepals deep purple, the petals
nearly white or tinged with pink, the

RANUNCULACEAE.
A NEW AQUILEGIA FROM THE HIGH MOUNTAINS.

Aquilegia madrensis Rose, sp. nov.

Stems 1 to 1.2 meters high, much branched above, pubescent becoming glabrate
below; basal leaves long-petioled, triternate; leaflets usually on slender petioles, 2.5
em. or less long, sometimes sessile, cuneate at base, irregularly cut or lobed, pale
green above, much paler beneath, pubescent; flowers nodding; sepals broadly ovate,
acuminate, 15 to 18 mm. long, puberulent; petals with a greenish rounded limb, the
spur 4.cem. long, very much contracted below the middle, pale red in color; carpels
5, strongly nerved.

Collected by J. N. Rose and E, A. Goldman on the Sierra Madre west of Bolafios,
September 15 to 17, 1897 (no. 2954).

Type U.S. National Herbarium no. 301908.

The species while near Aquilegia skinneri must be distinct, judging from the descrip-
tions and colored figure of that species. The plant is taller and not glabrous like A.
skinneri, the sepals broader, the leaf segments different, while the flowers are paler.
Aquilegia skinner is a Guatemala species and is perhaps restricted to that country.
The Mexican specimens labeled A. skinneri which T have seen seem best referable to
this species. These are Dr. EK. Palmer's no. 336 from Chihuahua, collected in 1885,
and Dr. Pringle’s no. 1182 from the same State, collected in 1887.

CAPPARIDACEAE.
THE MEXICAN SPECIES OF WISLIZENIA.

Dr. E. L. Greene has published in the Proceedings of the Biological
Society of Washington“ a revision of the genus Wislizenia. Of the
ten species enumerated by him five are attributed to Mexico, while
two or three of the others may be looked for on the Mexican side of
the border. Of the new species distributed three were collected by the
writer in Mexico. Of my collections Dr. Greene has this to say in
his preface:

“While pursuing this line of research, Mr. J. N. Rose pleasantly
surprised me by bringing forth a series of species of his own gather-
ing in Sonora and Lower California, upon which he had undertaken a
critical study long since, which study had been interrupted, and these,
together with the manuscript on them, he generously submitted to
me, as an aid to this general revision, His own Sonoran species,
both of them well marked in character, conclude the subjoined list of
species, nm »stly new.”

Wislizenia pacalis Gireene, Proc. Biol. Soc. Wash. 19: 131. 1906.

“Branches stout, often tortuous or flexuous, not quite glabrous, red-dotted, or
purplish; leaflets always 3, oblong, usually very obtuse or even retuse or emarginate,

2 to 38cm. long; racemes remarkably short, sessile; fruit short, only 3 to4 mm. wide;
carpels mostly round-obovate, in some specimens longer and subpyriform, the
prominent striae 5 only, ending in a more or less distinct low tubercle, the inter-
vening spaces conspicuously reticulate.

Rose, no. 1311 as in U. 8. Herb.; but these specimens have longer and even acutish
leatlets; but the peculiarly reticulate carpels are about the same in all and are far
more like those of the Texan and original W. refracta than like those of W. palmeri;
and Mr. Rose found himself unable to refer them to either species; his label bearing,
in his hand, nothing but the name of the genus.”

Wislizenia costellata Rose; Greene, Proc. Biol. Soc. Wash. 19: 132. 1906.

“Growing parts minutely and sparsely scaberulous; whole herbage more than
usually glaucous, the branches very leafy, somewhat tortuous; leaves and their peti-
oles of about equal length; leaflets cuneate-obovate, obtuse, only 1.5 to 2 em. long;
racemes subsessile, 1 to 1.5 dm. long; fruit only 3 mm. wide, the carpels at sum-
mit almost as thick as long, truncate at both ends, marked longitudinally by 5 or
6 ribs and many intervening closely compacted strive, the main ribs gradually thicker
toward the summit, where each ends in a stout low tubercle.

Wislizenia mamillata Rose; Greene, Proc. Biol. Soc. Wash, 19: 132. 1906.

“Glabrous; leaves on slender petioles nearly as long as the leaflets, the latter also

raceme stout and elongated, 10 to 20 em. long, short-peduncled; fruit about 6.5 mm.

all reticulate, somewhat constricted above the base, thence abruptly widening toa
broad and strongly mamillate-tuberculate summit.

or unifoliolate.’’

CAESALPINIACEAE.
TWO NEW SPECIES OF CASSIA.

In the last number of these studies I published four species of Cas-
sia. Since then two additional species have been discovered and these
are here described.

Cassia articulata Rose, sp. nov.

A shrub, two meters high, the young parts densely stellate-pubescent; leaflets
usually 4 pairs, ovate, 1.5 to 3.5 em. long, acute or obtuse, densely stellate-pubescent

ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 267

on both surfaces; rachis as well as pedicels and sepals also densely stellate-pubescent;
gland between leaflets of lower pair narrow-elongated; pods 6 to 8 cm. long; many-
jointed, strongly stipitate.

Collected by C. A. Purpus at San Pablo, near San José del Cabo, Lower California,
in 1901 (no. 287, type) and by Nelson and Goldman between Miraflores and San
Bernardino ranch, in Sierra La Laguna, Lower California, January, 1906 (no, 7418),

Type U.S. National Herbarium no. 470361.

This species is nearest C. villosus, but has small and differently shaped leaflets, a
much narrower gland between the leaflets, fewer-flowered inflorescence, and per-
haps a longer stipe to the pods.

Cassia macdougaliana Rose, sp. nov.

A low compact shrub, 30 to 60 em. high; branches puberulent; stipules ovate,
acute, dry, subpersistent; leaflets usually 3 or 4 pairs, short-oblong, 3 to 5 mm. long,
mucronately tipped, glabrous above, puberulent beneath, thickish, the veins indis-
tinct above, somewhat prominent beneath, rachis puberulent, bearing a stipitate
cup-shaped gland; flowers borne toward the ends of the short branches, axillary,
solitary; peduncle slender, puberulent; sepals membranaceous, obtuse; petals large,
deep yellow, pods 3 em. long, flat, nearly glabrous.

Collected by J. N. Rose in company with Dr. D. T. MacDougal near Tehuaciin,
Puebla, September 1, 1906 (no. 11253, type) and near the same locality by Rose and
Hay in August, 1901 (no, 5888).

Type U. 8. National Herbarium no. 454036.

This species is nearest C. gregyi/, from northern Mexico, but differs in its shorter,
less glossy, and less reticulated leaflets.

Casvia greggit was referred by Bentham to his subgenus Chamaecrista, and it has
since keen transferred to the genus Chamaecrista, but its relationship is clearly not
there.

ANEW SPECIES AND TWO CHANGES OF NAME IN CHAMAECRISTA.

A careful review of the various species of Chamaecrista in Mexico
has brought to light one undescribed species and revealed the necessity
of one change of name and one transfer from Cassia to Chamaecrista.

Chamaecrista amplistipulata Rose, sp. nov.

Suffrutescent and branching at base; stems somewhat zigzag, angled, glabrous, 20
to 30 cm. long; leaves closely set, 4 to 8 cm. long; stipules broadly ovate, tapering
into a spinescent point, strongly nerved, long-ciliate; leaflets 30 to 40 or even more
pairs, linear, 3 to 7 mm. long, acute, thickish, strongly 3-nerved below, either gla-
brous or ciliate; gland cup-shaped, sessile; flower buds acuminate; sepals thin,
puberulent; petals 12 mm. long; ovary cinereous-pubescent; pod 38 to 4 cm. long,
slightly hairy.

Collected by E. W. Nelson near Santa Efigenia, Oaxaca, July 18, 1894 (no, 2850).

Type U. 8. National Herbarium no, 229222,

This species belongs in Bentham’s series Coriaccae of Chamaecrista, but it seems
not very near any species described by him.

Chamaecrista chamaecristoides (Collard.) Rose.

Cassia chamaecristoides Collard. Hist. Cass, 154. 1816.

not as to plant.

In 1768 Miller described in his Dictionary a plant from Vera Cruz, Mexico, col-
lected by Houston, which he referred to Cassia chamaecrista 1. In 1816 Collardon

described his CL chamaecristoides, basing it on this same plant of Houston’s. In 1830
Chamisso & Schlechtendahl described their Cassia cinerea from a plant growing in
the sands of Vera Cruz, identical with Houston’s plant. This name.has since been
used, but must now give place to the earlier name of Collardon. Bentham has
referred C. chamaecristoides to C. procumbens, but surely this isa mistake. In a note
he states that some of the larger specimens seem to approach (. cinerea.

VICIACEAE.
FIVE NEW SPECIES OF BRONGNIARTIA.

The genus Brongniartia is chiefly Mexican and in Mexico is repre-
sented by many species. Of these Mr. Hemsley enumerated 17 in the
Biologia Centrali-Americana, but at present the number described
(including the following) reaches about 30. While a synopsis of the
genus was being prepared several additional species were discovered,
five of which are here described.

Brongniartia peninsularis Rose, sp. nov.

A shrub, 2 to 3 meters or more high with many slender, more or less zigzag,
branches, when young densely silky-pubescent; stipules leaflike, broadly lanceolate,
10 mm. long; leaflets 5 to 13, lanceolate, acute, 1 to 2. cm. long, with appressed cin-
ereous pubescence on both surfaces; flowers axillary; peduncle 2 to 2.5 em. long,
pubescent, bibracteate at base; bracts probably large; calyx tube glabrous, the lobes
pubescent on the margin and inner surface; corolla 1.5 em. or more long; pods gla-
brous, shining, 4 cm. long.

Collected by EK. W. Nelson and E. A. Goldman about 5 miles southwest of El
Potrero, Lower California, October 31, 1905 (no. 7236).

Type U. 8. National Herbarium no. 5653821.

This species is quite unlike B. trifoliata, the only other species from Lower Cali-
fornia, as well as the other Mexican species.

Brongniartia .asiocarpa Rose, sp. nov.

Low bush, 30 to 40 cm. high; young branches densely pubescent; leaves small for
the genus; leaflets 11 to 17, oblong to orbicular, 5 to 7 mm. long, obtuse, mucronate,
glabrate and shining above, somewhat hairy beneath, rather thick, more or less
reticulate on both surfaces; flowers axillary; fruiting peduncle only 5 to 7 mm. long,
bearing small bractlets near the top; calyx tube and lobes very hairy without; pod
2 cm. long, very pubescent.

Common on hills near Tehuacin, collected by J. N. Rose, August 1, 2, 1901 (no.
5910), and again in September, 1906 (no. 11256, type); and by C. A. Purpus in
June, 1903.

This species differs from all others which I have seen in its very hairy pods.

Type U. 8. National Herbarium no. 454039.

Brongniartia parvifolia Rose, sp. nov.

A low, spreading shrub 15 to 45 em. high; young parts very pubescent; leaflets 19 to
31, crowded, narrowly elliptical, mucronate, 6 to 10 mm, long, pubescent on both
sides; stipules in size and shape much as the leaflets; peduncles axillary, solitary,
about 10 mm. long, pubescent; bracts subtending the calyx ovate, acute, hairy; calyx
glabrous, 2-lipped, the tube 3 to 4 mm. long; upper lip 2-toothed; lower lip cut into

Brongniartia revoluta Rose, sp. nov.

Shrub 60 to 90 cm. high; leaves rather small for the genus; leaflets 9 to 13, oblong,
4 to 18 mm. long, glabrous above, appressed-pubescent beneath, the margin revolute;
flowers axillary; bracts at the base of the tube pubescent; pods cuneate at. base,
glabrous, 3 to 4 cm. long, 2 or 3-seeded.

Collected by E. W. Nelson on west slope of Mount Zempoaltepec, Oaxaca, July 3
to 13, 1894 (no. 564).

Type U. 8S. National Herbarium no. 469218.

Brongniartia goldmanii Rose, sp. nov.

Small tree 2 to 38 meters high; pubescence on young parts short, dense, spreading;
leaflets 7 to 9, shortly oblong, 2 cm. or less long, rounded or even retuse at apex,
pubescent on both surfaces when young, but soon glabrate above; flowers axillary on
peduncles 10 mm. or less long; bracts at base of calyx orbicular, 7 mm. long, pubes-
cent; calyx tube hairy; pods subsessile, never exserted above the calyx tube, 4 em.
long, glabrous.

ruary 22, 1899 (no. 322).

Type U. 8. National Herbarium no. 360243.

NEW SPECIES AND NEW COMBINATIONS UNDER CRACCA.

The need of a careful revision of the Mexican species known under
Tephrosia has long been apparent to the writer, who has several times
studied them with the hope of presenting a synopsis, but so many of the
older species are still poorly represented in our American herbaria
that it has not seemed hitherto nor does it yet seem wise to attempt a
revision. Most of the existing descriptions have been studied, how-
ever, and a large series of recently collected specimens have been
examined, resulting in the description of a number of new species.
The substitution of the older name Cracca also requires the making of
a number of new combinations, a part of which are here presented.
The excuse for publishing thus fragmentarily on this genus is that
my correspondents desire names. in order that they may publish upon
or distribute their material, and particularly. that several species are
found to be the hosts of fungi and their names are wanted in this con-
nection.

Cracca affinis (S. Wats.) Rose.

THREE NEW SPECIES OF DIPHYSA.

The genus Diphysa, a characteristic arid tropical genus, has a wide
distribution in Mexico, but only a few species have been described.
After a somewhat exhaustive study of the genus | wish to propose
the three following species:

Diphysa occidentalis Rose, sp. nov.

Shrub or small tree, glabrous throughout; leaflets about 20, oblong, acute; inflo-
rescence few-flowered, sometimes only 1 or 2-flowered; calyx glabrous, except the
ciliate lobes; petals yellow; pods oblong, much inflated, 4 to 8 mm. long, subsessile.
Specinens examined;

Sonora: Guaymas, Dr. FE. Palmer, 1887 (no. 198, type).

Colima: Manzanillo, Dr. E. Palmer, December 1 to 31, 1890 (no. 890); city of
Colima, M. FE. Jones, July 2, 1892 (no. 177).

Sinaloa: Culiacan, Dr. E. Palmer, August 27 to September 15, 1891 (no, 1498).

Guerrero: Acapulco and vicinity, Dr. E. Palmer, October, 1894, to March, 1895
(no. 106a),

This species seems to have a wide range, extending down the west coast of Mexico
from Guaymas to Acapulco.

Type U.S. National Herbarium no. 40567.

Diphysa minutifolia Rose, sp. nov.

Shrub, 1 to 2 meters high; old branches either gray or cherry red; first year’s
branches puberulent; leaves small, narrow, 2 to 6 cm. long; stipules linear, 2 to 3
mm. long; leaflets numerous, sometimes as many as 40, small, 4 to 6 mm. long,
oblong, obtuse, pubescent when young, glabrate in age; inflorescence much reduced,
sometimes only 1 or 2-flowered; bractlets not seen, doubtless caducous; calyx
slightly pubescent, perhaps becoming glabrate; ovary pubescent; pods 4 to 5 cm,
long, inflated.

Collected by C. G. Pringle in a barranca near Cuernavaca, Morelos, June 25, 1896
(no. 6876, type), and near Yautepec, Morelos, by C. G. Pringle, May, 1904 (no.
11963); also at the latter place by Rose and Painter, August, 1903 (no. 6568).

Type U.S. National Herbarium no. 491996.

This species is not near any other Mexican species.

Diphysa echinata Rose, sp. noy. ,

Low shrub; young parts with some soft pubescent and many stiff yellow, almost
prickly hairs; leaflets about 12, orbicular to oblong, 1.5 to 2 cm. long, very thin,

NEW SPECIES AND NEW COMBINATIONS IN PAROSELA.

I have published in previous numbers of the series “ two short pa-
pers containing many species. There is still a considerable number
of the so-called Daleas which have not been transferred to Parosela,
of which some are not known to me. The following list represents
species which either are new or are old species which I have recently
studied and believe to belong to Parosela.

Through the kindness of Col. D. Prain, Director of the Royal
Botanic Gardens, Kew, and Mr. W. Botting Hemsley I have obtained
fragments from seven types of Dalea belonging to the Kew Her-
barium, all but one being of species described by Mr. Hemsley himself.
Three of these not already transferred to Parosela are here placed
under that name.

Parosela anthonyi (Brandeg.) Rose.
Dalea anthony Brandeg. Erythea 7: 2. 1899.

Parosela campylostachya Rose, sp. nov.

Perhaps annual; branches glabrous or nearly so, bearing prominent glands; leaf-
lets 21 to 45, glabrous, 2 to 3 mm. long, the margins revolute, bearing large glands
beneath, glandless above; racemes short-peduncled, many-flowered; calyx 10-ribbed,
glabrous without, bearing | or rarely 2 large glands between the ribs; teeth short
and broad, hairy within; petals purplish.

Collected by Dr. C. G. Pringle near Cieneguilla, Oaxaca, November 1, 1894 (no,
5657).

Type U. 8. National Herbarium no. 305786.

This species was originally distributed under the name Dalea nutans, to which it is
not closely related. It is very near Parosela lasiostoma Rose, but has more numerous
and smaller leaflets, these more inclined to be revolute.

Parosela hospes Rose, sp. nov. :

A slender shrub 2 to 3 meters high; branches slender, perfectly glabrous, more
or less purplish; leaves glabrous throughout; leaflets 5 to 7, oblong to spatulate,
retuse, sometimes simply rounded at apex, 6 to 10 mm. long, the under surface cov-
ered with glands, the upper surface simply pitted; inflorescence a weak terminal
raceme 5 to 6 cm. long; bracts broadly ovate, acute, glabrous, very glandular;
pedicels short but distinct; calyx tube short, 2 to 3 mm. long, at first very silky
without, the teeth oval and ciliate, the lower tooth a little longer; petals creamy
white to pale rose color; stamens 10; ovary somewhat hairy, containing 2 ovules.

Collected by C. G. Pringle in the Sierra Madre above Monterey, in 1888 (no. 1904,
type) and 1903 (no, 11417); also by Dr. E. Palmer in the Caracol Mountains, Coahuila,
in 1880 (no. 210).

Type U. 8. National Museum no. 24351.

Dr. 8. Watson in reporting on Dr. FE. Palmer’s plants of 1880 calls this plant a
variety of Dalea frutescens, but does not give ita name. It differs strikingly from that
species in several respects. The flowers are in racemes instead of spikes, the calyx

lets are fewer and larger, and it has a different geographical range.
The specific name is given as this plant is the host of Apodanthes pringlei S. Wats.

tube; petals purplish; keel and wings attached to the stamen tube near its base.

Collected by William E. Safford, February 3, 1907 (no. 1246). The same species
was collected in 1880 (no. 208) by Dr. E. Palmer in the Sierra Madre 40 miles
south of Saltillo and distributed as Dalea polycephala, D, polycephala, however, has
pubescent stems and leaves.

THE GENUS MORKILLIA.

The following account of Morkillia, which recently appeared in the
Smithsonian Miscellaneous Collections, is here reprinted (without
change except in the citations) for the sake of connection with my
other Mexican studies.

The genus Chitonia has hitherto been represented only by material collected many
years ago. Until now it has rested upon a single species, C. mexicana, Fruiting
specimens of this were collected in 1905 near Tehuacin, Mexico, and in 1906 fruit
and flowers were obtained from the same place. Some years earlier, Mr. KE. W.
Nelson had collected in Northern Mexico .

THE MEXICAN SPECIES OF PTELEA.

Dr. E. L. Greene has recently published an exhaustive treatment of
the genus Ptelea in these contributions,“ in which 14 Mexican species
are described, all but one of them as new. Three of these, however,
he has since segregated as a new generic type under the name Tara-
valia. Below will be found the eleven species of Ptelea attributed to
Mexico. Dr. Greene’s descriptions of three of these, two based by
him on material collected by the writer, the third earlier established
by the writer on material of Mr. Pringle’s, are reprinted in full.

Ptelea acutifolia Greene & Rose, Contr. Nat. Herb. 10: 68. 1906.

“Twigs of the season dull chestnut-color, rather sharply and angulately rugose and
puberulent, the older glabrate, darker, obtusely and tortuously striate: leaves firm
but not subcoriaceous, deep green above, paler beneath and _ villous-strigulose,
definitely crenulate, all on elongated petioles mostly 6 to 8 em. long; odd leaflet
lance-elliptic, very acute at both ends, 5.5 to 8 em. long, the pair usually but little
smaller and of the same outline, being scarcely inequilateral: samaras small for the
foliage, transversely subquadrate-orbicular to quite orbicular, the largest and most
quadrate 2 em. wide, 1.5 em. long, such subtruncate at both ends; body very round-
ovoid, hardly as broad as the wing, lightly circumvallate, not at all sharply trans-
verse-rugose, moderately punctate; style and stipe nearly equal.

“State of Jalisco, Mexico, on the road between Huejuquillaand Mesquitec, August
25, 1897, Dr. J. N. Rose, no. 2580, as in the National Herbarium. Species not other-
wise known, and remarkable for the great length of the petioles, the. leaflets not
acuminate, though very acute.’’

Distribution: Sonora.

Ptelea laetissima Greene & Rose, Contr. Nat. Herb. 10: 69. 1906.

“Twigs of the season dull red-brown, lightly rugulose, puberulent, the older dull
brown, glabrate, smoothish: leaves small, of a light very bright green above, light dull
green beneath, with faint trace of minute scattered hairiness on both faces, but to the
unaided eye glabrous; odd leaflet lanceolate, acutish at both ends, about 5 cm. long,
the pair similar and hardly inequilateral, only about half as large, all sessile, obso-
letely crenulate: samaras large for the foliage, greenish in maturity, orbicular, about
1.8 cm. long and broad, truncate at base, emarginate at apex; body oval, of less than
the width of the wing, prominently rugose, but the wrinkles not very continuously
transverse, punctuation not strong; style and stipe nearly equal, both slender yet
prominent.

‘‘Near Tehuacan, State of Puebla, Mexico, September, 1905, collected by Messrs.
Rose, Painter, and Rose (no. 9927), type in the National Herbarium. The speci.

nished as if that of early summer at the North, are evidence that the species comes
into leaf and flower only late in summer, after the beginning of the rainy season.

‘“‘We have in the United States no Ptelea to equal this in the beauty of its bright
green almost brilliant foliage, a strong tinge of which is held by even the mature
fruit.’’

Ptelea megacarpa Rose, Contr. Nat. Herb. 10: 68. 1906.

‘‘Twigs tortuously striate rather than rugulose, and with glands between the lines;
bark chestnut-colored when mature, glabrous: leaves large, of thin texture, vivid
dark-green on both faces, scarcely lighter beneath and not in the least glaucescent,
glabrous ; leaflets ovate-elliptic, the pair almost or quite as large as the odd one,
oblique rather than notably inequilateral, all cuspidately acuminate, entire, the odd
one 7 to 12 cm. long: samaras very large, thin and flat, the circumscription exactly
orbicular, abruptly subcordate at base and equally obcordate-notched at apex, both
the length and breadth about 3.5 em.; body small in proportion to the wing, circum-
vallate, transverse-rugose, almost dotless, as also the wing; style of thrice the length
of the stipe.

“Dr. Rose establishes this handsome species on Mr. Pringle’s no, 8868 (type in the
National Herbarium), from the State of Hidalgo, Mexico; and it has been so
distributed.

‘‘Mr. Pringle reports it to attain the dimensions of a small tree at about 1,600
meters altitude below Trinidad Iron Works, where it was obtained by him June 2,
1904. Flowers were collected May 10, but unhappily none but the pistillate ; so that
the character of the filaments can not be given.”’

SIMARUBACEAE.
THE MEXICAN SPECIES OF CASTELA.

The species of Castela are very characteristic desert undershrubs,
and their distribution ought to be carefully worked out. The study
of our very scanty material has shown one new species, which is here
described. Also the variety of C. nichelsoné is here raised to specific
rank, The four Mexican species, one of which is very doubtful, are
the following :

Castela lychnophoroides Liebm. Vidensk. Meddel. 1853: 110. 1854.
This plant is an uncertain Castela. I have not yet been able to find it at the type
locality. The description suggests that it may not belong to this genus.

Castela peninsularis Rose, sp. nov.

Thorny shrub; pubescence on branches and thorns short, dense, velvety, yellowish ;
leaves cblong, 1 to 2 em. long, entire or few-toothed, somewhat revolute, the
pubescence on the under surface soft but not matted; flowers axillary, red; stamens
pubescent. .

Collected by C. A. Purpus at San José del Cabo, Lower California, March, 1901
(no. 244).

Distributed as C. tortuosa, but different in its leaves and pubescence.

Castela texana (Torr. & Gr.) Rose,

Castela nickelsoni terana Torr, & Gr, Fl. N. Am, 1: 680, 1840.

Castela tevana has generally passed as the Castela nickelsoni of the West Indies, a
very different species. Its relationship is more closely with C. tortuosa of South
Mexico, from which it differs in its somewhat narrower leaves, these more strongly
reticulated beneath and in its more yellowish pubescence.

Castela tortuosa Liebm. Vidensk. Meddel. 1853: 110, 1854.
This species has long been a desideratum in our larger herbaria. In 1905 it was
collected by Rose and Painter from near the type locality, Tehuacin, Mexico.

ADDITIONAL SPECIES OF TEREBINTHUS.

In No. 5 of this series a list of 50 species of Terebinthus was given.4
Since its preparation several new species have come to hand and these
with several others which had been overlooked are here presented.

Terebinthus acuminata Rose, sp. nov.

Small shrub, 3 to 4 meters high, the trunk and older branches shedding the bark
and becoming reddish-brown; leaves large, pinnate; rachis of leaf terete, pubescent;
leaflets 5 to 7, broadly lanceolate, acuminate, 6 to 10 em, long, glabrous or nearly so
above, somewhat pubescent beneath, especially on the veins; fruit in rather dense
racemes, shortly oblong, labrous.

Collected by J. N. Rose and Joseph H. Painter on a hill near Chapala, Jalisco,
October 5, 1903.

Type U.S. National Herbarium no. 451271.

thin (at least on flowering specimens), perfectly glabrous on both surfaces except
for some tufts of hairs in the lower axils of the veins on the under surface; racemes
slender, clustered at the ends of the second-year branches, 10 to 15 cm. long, glab-
rous; pedicels slender, 1 to 2 cm. long, glabrous; immature fruit glabrous,

this species is quite distinct and will be taken up under a different specific name by
Mr. T. 8. Brandegee.

Terebinthus pubescens (Schlecht.) Rose.

Elaphrium pubescens Schlecht. Linniwa 16: 527. 1842.

Rachis of leaf winged; leaflets 7, 3 to 5 em. long, narrowly elliptical, acute and
acuminate, cuneate at base, entire below, coarsely and irregularly toothed above,
pubescent on both sides; inflorescence as long as the leaves; calyx teeth 4, very short,
ciliate; petals 4, elliptical, obtuse, somewhat narrowed at base, glabrous.

Type locality: ‘EF campeche.”’

Probably common in Yucatan.

This species is not recognized by Dr. Engler or other writers on this genus. As
suggested by Schlechtendal, it isnear Bursera grareolens, but it is apparently distinct.
Before studying this species I had segregated from 7. graveolens material from Yuca-
tan, which I now find answers very well to 7. pubescens.

Terebinthus trijuga (Ramirez) Rose.

MALPIGHIACEAE.
THRYALLIS.

The genus Thryallis was published by Linnieus in the second edition
of his Species Plantarum” basing it upon a single species 7. drasi/7-
ensis. In 1829 Martius described two additional species 7. /ongifolia
and 7. latifolia.

These two species, however, were soon found not to be congeneric
with the original species, but instead of being taken out as a new gen-
eric type,’ were allowed to remain as Thryallis, while the true type of
that genus was transferred to Galphimia®. The following species either
are new or have been published under Galphimia,

Cnidoscolus palmeri (8. Wats.) Rose.

Jatropha palmeri 8. Wats. Proce. Am. Acad. 24:76. 1889.

This rare species has heretofore been known from a single flowering plant found
by Dr. E. Palmer near Guaymas, Mexico. Messrs. Nelson and Goldman have now
collected both flowering and fruiting specimens some 20 miles east of San Ignacio,
Lower California. These specimens, unlike the type material, have the long sting-
ing hairs so characteristic of C. wrens and C. stimulosa.

The inflorescence consists of only a few flowers; the fruit is shortly oblong in out-
line and about 1 cm, long.

Mozinna paucifiora Rose, sp. nov. PLATE XXII.

A large compact bush often with many stems, 3 to 4 meters »igh and often as
broad; branches usually stunted, very young branches densely po bescent but older
ones glabrate and reddish; leaves and flowers often borne in fase’cles from old nodes
on very short spurs, these crowded with the old stipules and persistent peduncles;
leaves simple, rather thin, broadly obovate to spatulate, 4 to 6 cm, long, rounded at
apex, narrowed at base into a short petiole, entire, softly pubescent on both surfaces;
stipules dissected into linear segments, these brown-pubescent and_ persistent;
flowers solitary, or sometimes several from the same spur, very short-peduncled,
1 to 2mm. long; ealyx 3mm. long, green, pubescent, its 5-lobes about 2 mm. long;
corolla red or pinkish, somewhat urn-shaped, 5 to 6 mm. long, pubescent without;
stamens in two whorls, the longer ones reachiz¢ the mouth of the corolla; fema e
flowers not seen; fruit glabrous, strongly flattened, 2 em. broad, 1.5 em. higa,
2-celled; seeds globular, 1 cm. in diameter.

Common on the dry hills east of Tehuacin, Puebla.

CELASTRACEAE.
NEOPRINGLEA AND ITS TWO SFECIES.

In July, 1891, Dr. 8. Watson proposed the name Neopringlea for
Llavea Liebm., while in the same year, but later (November), Dr. Otto
Kuntze proposed also the name Henningsocarpus.

The relationships of this genus are still doubtful, but for the pres-
ent I shall leave it in Celastraceae, where it usually has been placed.

The two species are as follows:

Neopringlea integrifolia (Hemsl.) 8. Wats. Proc. Am, Acad. 26: 135. 1891.
Neopringlei viscosa (Liebm.) Rose.

RHAMNACEAE.
SIX SPECIES OF CEANOTHUS, FOUR NEW.

Ceanothus australis Rose, sp. nov.

Shrub, 2 to 3 meters high, spineless; branches very regular, elongated, 10 to 15
cm. long; leaves opposite, 10 to 18 mm. long, much longer than the internodes, one-
nerved, thick, often retuse at apex, pale green; stipular glands large and long-per-

Collected by E. W. Nelson near Coixtlahuaca, Oaxaca, November 12, 1894 (no. 1914).

Type U. 8. National Herbarium no. 569221.

This species belongs to the section Cerastes and is perhaps nearest (. greggii, but it
has much longer branches and larger leaves.

Ceanothus candolleanus Rose, sp. nov.

Bush 3 to 5 meters high; young branches pubescent; leaves oblong, above gla-
brous or at least glabrate, beneath densely brownish-tomentose, 5-nerved, rather broad
at base, obtuse, serrate, the teeth tipped by red (in age black) glands; pedicels slen-
der, 4 to 5mm. long, glabrous, bluish; calyx teeth acute; petals blue.

C. bicolor Humb. & Bonpl. and the C. caerulea of Humboldt, Bonpland, and Kunth,
but their plant is described as having acute leaves and very short pedicels (1 line
long).

Ceanothus goldmanii Rose, sp. nov.

Shrub 2 to4 meters high; young branches reddish-pubescent; leaves opposite;
ovate to orbicular in outline, acute or obtuse, the margin bearing a few sharp teeth,

This species has heretofore been passing as C. rigidus, but it grows in very different
situations, and has very characteristic leaves with white instead of pink flowers.

Ceanothus lanuginosus (Jones) Rose.

Ceanothus greggii lanuginosus Jones, Proc. Calif. Acad. II. 5: 629. 1895,

Mr. Jones’s variety seems quite distinct from the true C. greggii and surely deserves
specific rank.

Ceanothus parvifolius (8. Wats.) Rose.
Ceanothus azureus parvifolius 8. Wats. Proc. Am. Acad. 28: 270. 1880,

Ceanothus submontanus Rose, sp. nov.

Shrub, 1 to 3 meters high, much branched; bark of first year’s branches reddish,
covered with soft cinereous pubescence, the older branches light gray; leaves
opposite, oblong-cuneate, pale and pubescent above, pubescent beneath, 6 to 16 mm.
long, entire, rounded at apex; pedicels slender, glabrous, and somewhat glutinose
in age; capsule globular, 5 mm. in diameter, bearing three prominent projections
above the middle.

Collected by FE. A. Goldman near Alamo, Lower California, July 11, 1905 (no.

5, 1905 (no. 1209).

The type is U. 8. National Herbarium no. 365049.

This species belongs to the section Cerastes and is nearest C. cuneatus, but differs
from the typical specimens of that species in the nature and color of the pubescence,
in having the leaves paler above and not so white beneath, and in its more globular
fruit.

VITACEAE.
A NEW CISSUS.

Cissus subtruncata Kose, sp. nov.

Stems creeping or climbing; softly pubescent; leaves broadly ovate, rounded-trun-
cate or slightly cordate at base, obtuse, acute or slightly acuminate, densely lanate-
pubescent beneath especially when young, more or less pubescent above; inflores-
cence compound, subumbellate, pubescent; pedicels slender, pubescent, nodding in
fruit; calyx cup-shaped, pubescent; sepals rounded, scarious-margined; pedicels gla-
brous, 2mm. long; ovary glabrous; style glabrous, 1 to 1.5 mm, long.

Collected by J. N. Rose near Oaxaca City, June, 1899 (no. 4614).

TILIACEAE.
. FOUR NEW SPECIES OF TRIUMFETTA.

The genus Triumfetta has long been in need of revision, and some
years ago I hoped to present a preliminary treatment of the Mex-
ican species, but I have not been able to finish it. While trying to
arrange the Mexican material in the National Herbarium I discovered
the following new species:

Triumfetta falcifera Rose, sp. nov.

Low, bushy shrubs, 90 to 150 cm. high; branches densely pilose; leaves lanceolate,
Jong-acuminate, rounded at base, 7 to 10 cm. long, with scattered simple and stellate
hairs above, densely and softly stellate beneath; flowers in small axillary clusters
or in narrow more or less elongated panicles; sepals densely pubescent, about 6 mm,
long, the appendages 4 mm. long, often 2-parted, sometimes 3-toothed; petals yellow;
stamens indefinite; fruit orbicular, covered with stout short prickles, nearly glabrous,
4-celled.

Collected by Dr. FE. Palmer near Acapulco in 1894-95 (nos. 63 & 266).

Type U.S. National Herbarium no. 266324.

Triumfetta dehiscens Rose, sp. nov.

Stems shrubby; young branches with dense reddish stellate pubescence; upper
leaves short-petioled, lanceolate, acuminate, very irregularly serrate, the lower teeth
glandular, the young ones very pale beneath, densely soft-stellate, greener and less
stellate above; fruit orbicular, covered with short glabrous prickles, 5-celled, dehis-
cing when mature.

Collected by J. N. Rose near Colomas, July 16, 1897 (no. 1698).

Type U.S. National Herbarium no. 300559.

Very different from most species of the genus, which have indehiscent fruit.
Triumfetta discolor Rose, sp. nov.

Plants growing in clumps, 60 to 90 em. high; branches pubescent with fine hairs
interspersed with coarse stellate or simple pilose ones; leaves with petioles about the
length of the blade, the blade nearly orbicular in outline and obtuse, rarely ovate and
acutish, 2 to7 cm. in diameter, greenish above with rough scattered stellate hairs, white
beneath with a dense stellate tomentum; inflorescence terminal in a mostly naked
narrow panicle; sepals 4 or 5, brownish, somewhat. stellate, the appendage slender
(2 to3mm. long); petals bright yellow, about the length of the sepals, hairy at base;
stamens about 20; fruit not seen.

Collected by J. N. Rose between Pedro Paulo and San Blascito, Territorio de
Tepic, August 4, 1897 (no. 1979 type), and on the east slope of the west range and the
west slope of the east range of the Sierra Madre in the State of Durango, August 13
and 15 (nos. 2255 and 3305).

Type U.S. National Herbarium no. 300870.

A very beautiful species which does not approach any other described from Mexico.
T. socorrensis has somewhat smaller but thicker leaves.

Triumfetta goldmanii Rose, sp. nov.

Branches at first covered with small stellate hairs but soon becoming glabrate;
leaves lanceolate, rounded at base, acuminate, green but with scattered simple,
appressed hairs above, paler and somewhat more pubescent (hairs also simple)
beneath, crenately toothed, 5 to 7 em. long; petioles short (in specimens seen), 1
em. long; flowers usually in umbels of 2 or 3; peduncles 1 to 3 in the upper axils, 3
to 4mm. long; pedicels 4 to 10 mm, long; calyx 15 to 16 mm. long, covered with
small stellate hairs without and bearing a small erect appendage just below the tip;
petals yellow; anthers reddish; ovary and fruit sessile; fruit glabrous but covered
with stout bristles, somewhat rugose, globose, 5 mm. in diameter.

Collected by E. A. Goldman on the Sierra de Choix, 50 miles northeast of the
town of Choix, State of Sinaloa, October 17, 1898 (no. 264).

MALVACEAE.
MISCELLANEOUS SPECIES.

Gaya violacea Rose, sp. nov.

A slender erect shrub up to 2 meters high, the branches clothed with short soft
pubescence together with long spreading hairs; petioles 4 to 6 cm. long; blade ovate,
acuminate, coarsely crenate, cordate at base, the sinus either narrow or closed,
becoming glabrate above, finely stellate-pubescent beneath; peduncles slender, a
little shorter than the petioles, pilose as wellas stellate-pubescent; calyx lobes ovate,
acute; petals violet; carpels 9, each one-seeded.

Collected by C. G. Pringle under dry cliffs on the Sierra Madre above Monterey,
1906 (no, 10221).

Type in U. 8. National Herbarium no. 462260.

This species is not very near any of the known Mexican species of Gaya, differing
from them all in its violet or purplish flowers.

Malvastrum“ bicuspidatum (S. Wats.) Rose.
Malvastrum tricuspidatum bicuspidatum S. Wats. Proc, Am. Acad. 21: 417, 1886.
In 1885 Dr. 8. Watson briefly described his variety bicuspidatum of Malvastriin
tricuspidatum, which Mr. FE. G. Baker later referred to Malvastrum seabrum, to which
it is much more closely related. In the National Herbarium we have considerable
material labeled M. scabruim besides the Wilkes specimen from Peru, which appears
to be true M. scabrum. A careful study of the Mexican species convinces me that the
supposed variety deserves specific rank. It differs from JM. seabrum in its smaller
leaves, these never cordate but cuneate at base, the flowers always solitary, the
peduncles shorter, the sepals more acuminate, the carpels also slightly different.
The following specimens have recently been collected:
Morelos: Near Cuernavaca, Rose & Painter, September, 1905 (no. 10246).
Guanajuato: Leon, Rose & Lozano, September, 1906.

Wissadula microcalyx Rose, sp. nov.

Stems herbaceous, | to 2 meters high, much branched, clothed with yellow glan-
dular spreading hairs; leaves broadly ovate, sometimes 3-lobed, the lower ones 15
em. long, acuminate, crenately toothed, cordate at base, stellate-pubescent beneath,
inflorescence paniculate; calyx small, the lobes broadly ovate; corolla deep yellow,
3 cm. in diameter; carpels obtuse, 3-seeded.

Collected by J. N. Rose on the mountains west of Tehuacin, September 12, 1906
(no, 11418).

Type U.S. National Herbarium no, 454200.

LOASACEAE.
TWO NEW SPECIES OF EUCNIDE.

Eucnida nelsonii Rose, sp. nov.

Pubescence on stems soft and spreading; leaves all petiolate, nearly orbicular, 5 to
60 mm. long, with rough pubescence on both surfaces, irregularly lobed and toothed;
pedicels 2 mm. or less long; calyx lobes linear-oblong, | em. long; petals erect, 2.5

mm. long; stamens numerous, longer than the petals.

«Malvaeopsis C. Presl has priority over Malvastrum and accordingly has been sub-
stituted for it by some writers. It is not at all clear to my mind that these two names
belong to the same genus and I therefore propose provisionally to retain Malvastrum,
The Vienna Congress has also retained this name, but for a different reason.

ing; leaves long-petioled, the upper ones often 7 cm, long, broadly ovate, 8 to 15 cm.

long, rounded at apex, more or less cordate at base; pedicels 2 to 3 em. long; calyx
15 to 17 mm. long; petals erect, 3.2 to 3.8 em. long; stamens numerous, 5 cm. long.

LYTHRACEAE.
SIX NEW SPECIES OF CUPHEA.

It is with considerable reluctance that I continue to use the name
Cuphea instead of Parsonsia, but Prof. E. Koehne, who has for so many
years given attention to the genus,
still thinks that Cuphea had better
be retained, and for the present I
have accepted his advice; but I still
believe that Parsonsia should be
used. Until Prof. Koehne or some
one else can revise and transfer all
the species these may as well wait
in Cuphea.

Dr. EK. Palmer calls this the ‘‘barrel cactus,’’ and states that it is cooked in syrup
and made into candy. F. EK. Lloyd writes of it as follows: “Biznaga burra. The
most striking cactus of this region, where it is found on the higher foothill slopes
and in the hills on the slopes facing the south, with only very few exceptions.
Growing point depressed, elongate-ovate, except in very young plants, in which it
is round, as in cacti in general; marked by a dense felt of wool of light brown color.
Two metersin height. Spines brown in young, yellow in old plants. Ridges furrowed
in older plants. Flowers entirely lemon-yellow, as well as the fruit, which is dry,
hollow, with persistent perianth.”’

ONAGRACEAE.

A NEW SPECIES OF GAURA AND ONE OF LAVAUXIA.

Gaura grandiflora Rose, sp. nov.

A rather coarse perennial, 40 to 60 cm. high; stems herbaceous, branching, the
axis percurrent, with both long and short pubescence; branches many, ascending,
more or less purplish; leaves lanceolate, 4 to 6 em. long, acute, somewhat toothed,
pubescent on both surfaces; inflorescence somewhat pubescent, often early glabrate;
ealyx buds glabrous; calyx tube slender, 3 to 3.5 cm. long; petals 2 to 2.5 em. long;
anthers linear, attached near their middle; ovary and fruit glabrous, the latter 7 mm.

Probably common in the mountains of Chihuahua and Durango. It has been con-
fused with Gaura mutabilis of central Mexico, but is easily distinguished by its gla-
brous calyx and fruit.

THE SUBFAMILY LOPEZIEAE.

Dr. Rudolf Raimann, in Engler & Prantl’s Pflanzenfamilien, has very
properly proposed the name Lopezieae for the irregular-flowered divi-
sion of the Oenotheraceae. He includes four generain this group. Of
these four genera three are monotypic, and hence practically all the
species of the group belong to one venus, viz, Lopezia. In the genus
Lopezia 33 species have been named or described and a considerable
number of new ones have recently been collected, of which 9 are to be
found in this paper.

A careful review of the material which has been accumulating in the
National Herbarium leads me to the conclusion that there are three
genera to be taken out of Lopezia, each of which contains two species.

Of the other genera, Semeiandra and Diplandra, a representation
has recently been added to the National Herbarium, but Reisenbachia
is only known to me from Presl’s plate.

The following key to seven genera should be helpful:

REISENBACHIA.“

The genus Reisenbachia is only known from Haenke’s material,
which Presl has described and figured. Only a single species has been
described and figured, this said to have been collected in Mexico, but
no definite locality given. This is one of the plants which should be
carefully looked for by Mexican collectors.

° DIPLANDRA.?

The only known species of the genus Diplandra was collected in
west Mexico by the botanists of the Beechey Exploring Expedition.
Since then no collection of it has been reported. We now have good
specimens obtained by Dr. E. Palmer from Tepic, near the type
locality.

SEMEIANDRA.*

The genus Semeiandra was first collected near Tepic by the botanist
‘connected with the Beechey Exploring Expedition and afterwards by
T. Coulter and B. Seemann in western Mexico. No recent collection
of it has been reported. We now have it in the National Herbarium
from Dr. E. Palmer’s collection made at Tepic, Nelson’s in Jaliseo,
and Rose’s in Sinaloa.

PELOZIA.
Pelozia Rose, gen. nov.

Sepals 4, linear, the lower one nearly distinct to the base, the three upper more or
less united, the central one bearing a large gland a short distance above the base
within, the two lateral ones forming with the lower one two small pouches or spurs at
their base; petals 4, the two lower entire, attached to the calyx, the two upper
borne on the three upper sepals; stamens 2, the lower petaloid, the upper perfect;
style single, short; fruit a 4-celled capsule, shortly to narrowly oblong. Delicate
annuals with thin alternate leaves, and small axillary flowers.

This genus ix nearest Lopezia, but is well separated by the characters given. The
fruit is not globular, but oblong, the sepals are not all distinct, but the three upper
are united for a part of their length, and the lower sepal, while nearly distinct, forms
with the adjacent sepals two short spurs. The three upper also bear a large gland
within. The two lower petals are borne at the base of the flower, while the two
upper are borne upon the sepals, are broader than the lower, and are not at all glan-
dular at the top of the spur as in Lopezia.

Lopezia insignis Hemsley is very different from true Lopezia and
clearly deserves generic rank. Mr. Hemsley has called attention to
some of its peculiarities and to its resemblance to Semeiandra grandi-
flora. Lopezia longifiora Decaisne seems to be congeneric.

LOPEZIA.%

A review of the names of 33 species of Lopezia has consumed a
large amount of time. Some of the results obtained have been very
gratifying, while others have been most discouraging. Of these species
only a few, in fact only four, have been described during the last fifty
years. Most of them have been very briefly characterized and they
have often been misunderstood. The material in our large herbaria is
much confused.

PREFACE.

The accompanying paper on the Allioniaceae, chiefly those of the
United States, is by Mr. Paul C. Standley, assistant professor of
botany in the Agricultural College of New Mexico. It was elab-
orated under the direction of Prof. E. O. Wooton, of the same insti-
tution. It embodies the results both of field work and of a study
of herbarium material from most of the western herbaria, as well as
the National Herbarium, and of all the literature of the subject. Mr.
Standley has aimed at a comprehensive and thorough treatment of the
whole group and has found it necessary to establish several new
genera and restore others not recently accepted. The number of
sheets studied belonging to the National Herbarium was 1,068. Of
the 50 new species here described the types of 20 are in the National
Herbarium, and others are represented here by duplicate types. The
illustrations, except Plates XXXIV and XXXV, are from drawings
made by Mr. Standley himself.

THE ALLIONTACEAE OF THE UNITED STATES, WITH
NOTES ON MEXICAN SPECIES.

By Taunt (. STANDLEY,

INTRODUCTION.

Of all the families of North American plants none, probably, have
been more neglected than the Allioniaceae. In the last fifty-five vears
no monograph of the American representatives of the family has ap-
peared, Linneus in the Species Plantarum published two North
American genera of this family—Mirabilis, with one species, and
Boerhaavia with four species, only two of which, however, occur in
the region under consideration. Other genera and species of the
family were soon published, all of them in scattered publications.
The first treatment of the family as a whole was that of Choisy in
De Candolle’s Prodromus. In that work, 10 North American genera
were described and, under them, 31 species, not including several
species of Pisonia. Choisy’s work is interesting and at times help-
ful, but the author labored under the difficulty of not having seen
some of the plants of which he wrote, as a result of which some seri-
ous mistakes were made. The next work of any importance dealing
with the family was that of Asa Gray, in the Botany of the Mexican
Boundary Survey;¢ that paper is a very brief one and includes de-
scriptions of but few species, although Gray described at various
times a considerable number of new genera and species in the Al-
lioniaceae,

Dr. Anton Heimerl, of Vienna, probably the foremost student of
this group of plants, contributed to Engler and Prantl’s Natiirlichen
Pflanzen-Familien ’ the section dealing with the Allioniaceae, a paper
valuable for the excellent discussion it contains of the various genera.
The work is exceedingly conservative, and the family is treated as

European botanists so commonly treat groups of American plants.
The genus Allionia, for instance, is made a mere section of Mirabilis,
and other adjustments of the same kind are made which. although
they may be the easiest way of disposing of genera, are certainly not
conducive to clearness.

In 1902 Mr. M. E. Jones published in his Contributions to West-
ern Botany“ a paper dealing with the family as it is represented in
the Great Plateau region, an area in which are found almost all the
species at that time known to occur in the United States. In the
same year there appeared in the Bulletin of the Torrey Botanical
Club? a paper by Dr. Per Axel Rydberg dealing with the Allioniaceae
of the Rocky Mountains and containing descriptions of a number of
new species, which is undoubtedly the most critical and valuable
publication dealing with any group of the American representatives
of the family.

The work, the results of which are here discussed, was carried on
at the New Mexico Agricultural College during the years 1907 and
1908. The writer had the privilege of examining all the material
of the Allioniaceae to be found in the herbaria of the following insti-
tutions and individuals: National Herbarium; Missouri Botanical
Garden, including the Engelmann and Bernhardi herbaria: Field
Museum of Natural History; University of California, including
the Brandegee Herbarium; University of Wyoming; University of
Nevada; University of Arizona; Mr. A. A. Heller, Mr. K. K. Mac-
kenzie, Prof. E. O. Wooton, and the New Mexico Agricultural Col-
lege. He wishes here to express his obligations to the curators or
owners of these collections; also to Mr. G. E. Osterhout, who furnished
material for examination. It was only through the kindness of those
who have charge of these various collections that this work was made
possible. The author is under special obligations to Prof. E. O.
Wooton, under whose direction the work was begun and completed,

The present paper is intended to cover all the representatives of
the family occurring within the United States and most of those
found in Mexico and the West Indies, with the exception of the genus
Pisonia.

The drawings are by the author, with the exception of Plates
AXNIV and XXXV, which are by the German artist, W. Liepoldt.
The author wishes especially to express his indebtedness to Dr. Anton
Heimerl, who forwarded to him the two latter drawings and the
descriptions which accompany them, with permission to use them
here. Doctor Heimerl’s notes attached to the sheets of the National
Herbarium have also in several instances been of great help in the
preparation of this paper.

SYSTEMATIC TREATMENT.

ALLIONIACEAE Reichenb. Consp. 85. 1828.
Nyctaginaceae Lindl, Nat. Syst. ed. 2. 213. 1836,

Annual or perennial herbs, often shrubs or trees, with branching or dichoto-
mous-forking stems; stems usually with swollen joints, sometimes armed with
spines; leaves opposite or alternate, simple, entire, or sometimes repand,
exstipulate; inflorescence various; flowers regular, perfect or sometimes uni-
sexual, often subtended by bracts which form a calyx-like involucre; perianth
consisting of a calyx only, this often showy and corolla-like, tubular, funnel-
form, or campanulate, usually deciduous above the ovary ; stamens 1 to many;
filaments filiform, distinct or united at the base, often unequal in length, ex-
serted or ineluded: anthers 2-celled, opening by longitudinal fissures; ovary
1-celled, superior but surrounded by the calyx tube, sessile or short-stalked ;
style slender; stigma usually capitate; ovule solitary, erect, sessile; fruit an
anthocarp, indehiscent, fleshy, leathery, or hard, angled, ribbed, grooved, or
winged: seed erect, with a hyaline testa which is free from or adnate to the
pericarp; endosperm variable; embryo straight or curved,

The fhmily consists of about 26 genera and 250 species. Most of the genera
and species are confined to the Western Hemisphere. In the Old World there are
found one species of Allionia, several of Boerhaayvia and Pisonia, and the mono-
typic South African genus Phaeoptilon, Of these only one, a species of Boer-
haavia, occurs in Europe (in southern Spain), the others being confined to
Africa, southern and eastern Asia, and the islands of the Pacific. Doctor
Heimerl mentions the fact that one or two American species have become
naturalized at various places in Europe.

In the Western Hemisphere there seem to be two centers of distribution, one
in tropical and subtropical South America and the West Indies, characterized
by such genera as Pisonia, Neea, Bougainvillea, and others; the other in
‘fexus, New Mexico, Arizona, California, and northern Mexico, especially
characterized by such genera as Boerhaavia, Abronia, Acleisanthes, Allionia,
but presenting several others. Of the entire number of genera included in
the family 16 occur in the latter region ewbracing more than 160 species. It
is the region about this center that this paper attempts to cover.

corolla-like, with an elongated tube which is constricted above the ovary,
expanding above into a 5-lobed limb; stamens 3 to 5, included, their filaments
unequal; fruit leathery, usually 3 to S-winged but sometimes only ribbed or
almost smooth: seed filling the pericarp, to which it adheres; one of the coty-
ledons abortive, the seedling thus appearing monocotyledonous,

Of the history of this genus Doctor Rydberg says: “tn the original publi-
cation no type species was mentioned. The genus was described from a plant
collected on Dé la Pérouse’s journey in California and cultivated by Mr.
Colignon. Hooker, in his Exotic Flora,’ identifies Colignon’s plant as A broenia
umbellata. The type of Tricratus is the same.”

The genus is a North American one and is confined chiefly to the western
part of the United States. One or two species extend into southwestern
Canada and three into northwestern and northeastern Mexico, On the east
the range extends into western Nebraska and IKkansas, and on the west to the
acifie const. The writer has seen no specimens from southern central Arizona,
where the genus would be expected to occur, since it is conmon to the east in
southern New Mexico and to the west in California, but Prof. J. J. Thornber
states that it is represented in that part of the Territory by one or more species.

Most if not all the species seem to be in a yariable or mutating state. They
are rather numerous and most of them are confined to comparatively small
areas. One of the most striking illustrations of the latter fact is found in
A. carletoni, the type of which was collected about sixteen years ago in eastern
Colorado. but which, as far as the writer is able to learn, has never been col-
lected since. Its closest ally has not been collected nearer than 350 miles to the
south.

The writer has tried, but with little success, to arrange the species in a lineal
sequence, There are so many different lines along which different species vary
that it is almost, if not quite, impossible to do this. There are several groups
of species, for instance, which are closely related to .t. fragrans; but these
groups vary in different directions so that it is impracticable to arrange them
in a lineal succession which will show their closest relationships. This is true
of sections as well as of species and applies equally to the other large genera such
as Allionia nnd Boerhaavia. It is also difficult to arrange the species in sections,
and the arrangement which is given here is not at all satisfactory on account
of the many intergradient species. The maritinut and latifolia groups are dis-
tinct enough. The fragrans and turbinata groups are most difficult of separa-
tion on account of such forms as A. carlefoni and uA. nealleyi, either of which
is as closely related to A. fragrans as to 1. turbinata, The nana group is
easiest to separate because of the peculiar habit of the plants, a habit with
which other peculiar characteristics are concurrent.

Among the various characters which are of use in separating species of
Abronia the habit is of importance, especially in the turbinata group. This is
a character that is not well shown in dried specimens generally, for in such
specimens it is difficult to tell whether a stem is erect, ascending, or prostrate.
The pubescence is variable, but not nearly so much so as in the genus Boer-
haavia. While the leaves upon a single plant are usually of the same general
shape, the earlier ones commonly differ somewhat from the later, especially in
size, It is worthy of note that in all the Abronias the opposite leaves are
unequal in size, sometimes very strikingly so, a peculiarity Characteristic of
some other genera of the family. The difference in outline in opposite leaves is
also sometimes conspicuous.

The size and shape of the involucral bracts are among the best characters
by which to distinguish species in this genus, for they show little variation

Within a group of plants that may be taken as a species; the same is true of
the size of the flowers. The color of the flowers is more or less variable, white-
flowered forms of normally red-tlowered species being occasionally found. The
fruit is perhaps of the most importance. The outer and inner fruits in a single
head are often very different in form: but the inver ones in different heads on
the same plant are remarkably uniform in shape. A word may be necessary
in explanation of the terms ‘“ turbinate” and “ biturbinate,” as employed by
Doctor Rydberg, whose usage I have followed. The distinction between the two
is difficult to understand from mere descriptions, but | hope that by reference
to the accompanying drawings it may be more easily grasped.

This is easily distinguished by its vellow flowers and orbicular
leaves. The species is variable in several respects; the Oregon
and Washington plants have broader leaves and thicker petioles
than those from California; their fruit has wider wings, which
are more often truncate above; and their bracts are frequently
much wider than those of southern specimens. Heller’s 8948 — Fic. 49.— Fruit

very long, so that the plant does not appear at all leafy, Type U. S. National
Herbarium no. 444666, collected on San Clemente Island off the coast of south-
erm California, by Mrs. Blanche Trask, October, 1902) (no. 50). A younger
plant from the same locality has slightly puberulent stems, leaves broader and
orbicular or broadly elliptical, the petioles longer than the blades. I doubt if
it is the same as the plant described above. Another specimen probably to be
placed here is one collected at Santa Barbara, 1902, Hlmer 38754.

large, 28 to 42 mm, long and almost as wide, very broadly ovate or rhomboidal,
thick and fleshy, minutely puberulent beneath and on the margins, the midrib

Distinguished from A. umbellata by its broader and slightly sinuate leaves,
its more scarious bracts, and its whiter fruit, the wings of which are much
broader and less narrowed below as well as more prolonged above. From
A. gracilis it differs in the thinner and much broader wings; in the shape of
the fruit, which is broader than long; and in the leaves being less sinuate and
the whole plant larger and stouter. From A. variabilis it is readily separated
by its larger leaves, more pubescent stems and leaves, broader bracts, and
larger flowers. Type in the herbarium of. the University of California, col-

This is much like A. villosa, but is a larger and stouter plaut; its flowers are
considerably larger, sometimes 3 cm. long; and its fruit is
broader than long, the body thick and large, vertically ribbed,
but with few or no transverse ribs, so that the fruit has not
the pitted appearance of that of A. villosa; the wings very
broad and usually elevated above the body of the fruit.

The plant differs from A. nana in its very minute pubescence which is not
glandular and its ovate leaves, in having lanceolate bracts which are not scart-
ous und are smaller than in that species, and in its smaller flowers.

truncate at the base, narrowed above to the obtuse apex, glabrous, or minutely
and sparingly puberulent on the lower surface; petioles as long as the blades or

below and sloping slightly above from the beak, not rising above it; outer fruits
irregular, with wings very narrow or wanting, sometimes biturbinate.

From A. torrceyi, to which this is most closely related, it may be separated
by its larger bracts, broader and more glabrous leaves, almost glabrous stem,
and wings without disks above; from A. lobatifolia it is distinguished by its
different leaves, more glabrous stem, and larger bracts.

or acutish at the apex, the base varying, unequal, semicordate, rounded, trun-
cate, or broadly cuneate, very minutely and sparsely puberulent; petioles

narrow beak, which is usually depressed below the wings; wings narrow, thin,
their corners rounded above, surmounted by conspicuous flat disks; seed 2 to
2.5 mm. long, lanceolate in outline, black, smooth.

This plant can be separated from A, angustifolia, its nearest relative, by
its smaller, narrower seed, broader leaves which are not attenuate at the base,
and more densely pubescent stem. Type U. S. National Herbarium no. 8380254,
collected at Mesilla, Donna Ana County, New Mexico, June 15, 1897, Wooton 11.
The plant is very common on the sandhills of the Mesilla Valley, flowering
from early spring until late in autumn, It has been confused with A. turbinata,
from which it can readily be distinguished by its prostrate habit and red flow-
ers, The fruit is distinct, also, and the general appearance of the plant is very
different. I have little doubt that this is the plant to which Doctor Torrey
originally applied the name A, turbinata. Doctor Watson, however, in publish-
ing the description had in mind another plant, one from Nevada which he bim-
self had collected and which he took to be the same as Doctor Torrey’s. It
is the Nevada plant which is figured in the plate accompanying the original
description of A. turbinata, and which is accordingly to be taken as the type,
although Doctor Watson also mentions several plants which are to be placed
‘ather in A. torreyi.

graph of the specimen which shows the characteristics of the plant almost
as well as the specimen itself could do, It is not the same as A. angustifolia,
as Mr. Jones claims, but seems to me much nearer A, fragrans, The bracts

I have seen no specimens besides the type that could be referred here. The
plant differs from A, sa/sa, which it most resembles, in its nar-
rower, lanceolate leaves, more densely leafy stem, smaller bracts,
and slightly different fruit.
The type is from Salt Lake City, Utah, 1879, Jones 1887,

long, densely puberulent; bracts scarious, broadly ovate, acute, 4 to 6 min. long
and 3 mm. wide; flowers 12 mm. long, numerous, their tubes puberulent; fruit
biturbinate, broadest about one-third below the sununit, 4 mm. long and almost

as wide, narrowly ridged.

This is a very distinct species because of its small bracts, harrow leaves, sinall
fruit and flowers, and low habit; the plant appears to be vigorous and not at
all like a depauperate form. Type in the herbarium of the Missouri Botanical
Garden, collected at Screw Bean, Reeves County, Texas, in 1893, by G. C. Nea l-
ley. In the National Herbarium there is another plant, collected October, ISS1,
in Texas by Havard, that should probably be placed here. One collected by
Havard at Odessa Tank, September, 1881, with the habit and general appearance
of A. nealleyi, but the fruit with prominent wings and not biturbinate, is prob-
ably of an undescribed species, but the material is insufficient for determination,

Perennial; stems erect, GO cm. high or less, very thick and stout, as much as
15 mm. in diameter, covered with an exceedingly dense short-hirsute pubescence :
plant very leafy; leaf blades ovate, 4 to 8 em. long, 2 to 5 em. broad, obtuse or
acute, cordate or trunente or broadly rounded at the base, densely puberulent
on both surfaces or sometimes almost glabrous above; petioles thick, as long as
or longer than the lower blades, those of the upper leaves shorter than the
blades; peduncles § to 11 cm. long, stout, hirsute: bracts 6, puberulent, scarious,
lanceolate, acuminate, 7 mm. long and 2 or 8 mm. wide: flowers numerous in
rather dense heads, 2 em. long, their tubes almost glabrous; fruits biturbinate,
the outer ones of the head strongly so, the inner less markedly so, narrow,
5 to Timm, Jong and 3 mm. wide, with a stout beak above; the outer fruits
merely ridged, the inner with narrow, thick wings or ridges, these not more
than 1 mm. wide,

Nearest A. fragrans, but more robust, its bracts nurrower, its stem densely
hirsute. The type material in the herbarium of the Missouri Botanical Garden
consists of 4 sheets collected on sand hills near Monahans, Ward County, Texas,
May 10, 1901, by H. Eggert. This is the most densely pubescent Abronia that I
have seen.

throughout; leaf blades rather broadly lanceolate, rather obtuse or acute at the
apex, unequally and rather broadly cuneate at the base or subcordate in young
Plants, 25 to 50 mm. long and 12 to 20 mm. wide, sparingly puberulent on both
surfaces, especially on the veins: petioles of the lower leaves as long as the
blades, those of the stem leaves shorter, hirsute; peduncles 2h to 60 min. long,
hirsute, stout: bracts elliptical, scarious, 12 to 15 mim. long and 5 to 8 mm,
wide, acute or sometimes cuspidate ; flowers many, 2 cm. long, with a limb about
3mm. wide, tubes densely puberulent : fruit harrowly turbinate, 9 mm. long and
© mun. wide, with a very small body and 4 or 5 narrow wings which are 2.5 mm.
wide, thin, rounded above, and projecting considerably above the body; the
outline of the fruit harrowly obcordate, the beak short and small, hispidulous
on beak and top of wings: seed 2 mun. long, dark brown, linear in outline.

The fruit of this plant is quite unlike that of A. fragrans, to which the species
is most closely related: the pubescence, too, is more dense. Type in the

Perennial, erect: stems more or less puberulent
throughout, rather stout; leaf blades ovate or elliptical,
rounded or narrowed at the base, mostly obtuse or
acutish at the apex, minutely puberulent and rough-
ened on both surfaces or glabrous above: bracts ovate
or broadly elliptical, acute or attenuate, 10 to 15 mm.
long and about 8 mm, wide; flowers 2 cm. long or more,
greenish-white; fruit 6 mm. long and 4 mm. wide or
often larger, usually distinctly biturbinate, the outer
ones strongly so and often irregular ; fruit not winged, but with low, thickened
ridges which are strongly veined.

The plants included here are, as a whole, remarkably uniform, although a
few variant forms will be found. A form of the species which extends into
western Kansas differs considerably in general appearance, but I have been
unable to separate it. A plant from Oklahoma is reported to have red flowers,
but otherwise it does not seem remarkable.

Abronia of various authors, in part.

Stout, much branched annuals, usually more or less pubescent, the pubescence
consisting of flattened, several-celled hairs: stems erect, ascending, or rarely
procumbent; leaves opposite, entire, usually unequal; involucral bracts 4 to G,
separate, folded over the flowers in the bud; perianth with a long slender tube
and a broad, expanded, 5-lobed limb: flowers in the involucre numerous; sta-
mens 5, with very short filaments, attached at irregular intervals to the upper
part of the tube of the perianth ; fruit almost orbicular in outline, with a cori-
neeous or spongious body, this often ribbed and completely surrounded by the
© to 4 broad wings, which are thin and strongly reticulate-veined ; stipe pro-
longed below through the membranous wings; seeds narrowly elliptical, cylin-
drical.

Type species, Abronia micrantha Torr. This is also the type of the genera
Cyeloptera and Apaloptera

This genus is well worthy of sepa ‘ation from the true Abronias because of
its peculiar fruit, whose wings completely surround the body. The central
cavity, moreover, does not extend into the wings as it does in all or most
species of Abronia. The plants are so different in general appearance, habit.
and especially in the appearance of the heads of the fruit, that no one can have
any difficulty in distinguishing the two genera at a glance, The two are
sharply defined, there being no intergradient forms.

Abronia cycloptera A. Gray, Am. Journ. Sci, If. 15: 319, 1853, excluding
synonyms,

Abronia carnea Greene, Pittonia 3: 343, 1898,

This name might very properly be reduced to synonymy if it were not for the
fact that certain excuses can be offered for it. Doctor G ‘ay evidently intended
it merely as a new name for Abronia micrantha because he considered the latter
naine inapplicable to specimens he had examined which were really not A.
micrantha at all, but a southwestern plant which resembles it somewhat. From
what he says at the time he proposed the name it can be definitely stated that
he had in mind the specimens collected by Wright in western Texas and not
the northern plant to which the name micrantha was originally applied. The
name will be considered a nomen nudum by some, or a mere synonym of 7.
micranthus, but the present author believes that long-established usage makes
it allowable and preferable to retain it.

Abronia carnea is certainly a synonym of 7, cyclopterus; the types of the two
came from localities separated by not more than 40 miles. The plant is not a
perennial, as Doctor Greene surmises in his description, but an annual which
blooms from early in the spring until late in the summer.

Annual: stems ascending. 25 em. high, with scattered rough pubescence
throughout, finer than that of 7. cyclopterus; leaf blades rather broadly lanceo-
late, 80 or 40 mm. long and 10 to 15 mm. wide, the margins sometimes slightly
undulate, ciliolate; blades with rather abundant chaffy pubescence beneath and
frequently above, acute or rarely rather obtuse, narrowed at the base into a
petiole as long as the blade or shorter: peduncle 6 cin. long, with rather abun-
dant viscid pubescence; bracts 11 to 15 mm. long and 2 mm. wide, narrowly
lanceolate, long-acuminate; flowers 25 to 30 mm. long, whitish or very pale
pink, tube densely glandular-pubescent, limb 9 mm. broad: fruit 15 to 20 mm.
long and almost as broad, hispidulous especially on the ribs and along the mar-
gins of the wings: wings not as much narrowed below as those of 7. cyclopterus,
rounded above, finely reticulate-veined, the body with usually 3 strong ribs be-
tween each pair of wings; seed 5 mm. long.

Most of the material from northwestern New Mexico and northeastern
Arizona which has passed as 7’. cyclopterus is to be placed here. This species
is distinguished from that by its considerably smaller, hispidulous fruit (the
fruit of some of the northern plants is much smaller than that of the type),
narrower bracts, more pubescent stems and peduncles. and pale flowers, and
by its lower, less erect habit: the leaves when fresh have a peculiar glaucous
appearance different from leaves of 7. cyclopterus, The differences in general
appearance between the two species are less apparent in dried than in living
material. Type in the herbarium of the New Mexico Agricultural College, con-

This plant differs from A. capitata in its thicker, subhastate leaves, rather
smaller flowers, and less exserted stamens. The difference in number of sta-
mens mentioned by Professor Nelson does not hold, neither does the difference
in their insertion. I have not been able to see any essential difference in the
shape of the lobes of the perianth in the two species. The flowers in this spe-
cies are of a mueh deeper red color, The plant seems to be a very distinct one,
readily distinguishable almost at a glance by its appearance, a species contined
in its range to the upper valley of the Rio Pecos,

Prof, 'T. D. A. Cockerell,* guided evidently by the original description of this
species, was led to found upon it a separate section of the genus under the name
Roswellia. The plant certainly does not differ generically from A. capitata,
us he was inclined to believe, and I think it can not be worthy even of a
separate section.

of each fruit in most species furnished in place of the ventral nerve with a crest
1 mm. high or more, with the margin entire or slightly toothed, the crest wider

The remarkable fruit of this plant separates it at once from any other
species of the genus. Type U. S. National Herbarium no, 349027, collected at

2. Wedelia glabra (Choisy) Standley.

Allionia incarnata glabra Choisy in DC, Prod, 18°: 435, 1849.

Annual; stems reddish, prostrate, much branched from the base, slender,
sparingly white-puberulent with rarely a few longer, soft, white hairs: leaf
blades oblong or elliptical, 28 mm. or less in length and 11 mm. or less in
width, obtuse at the apex, rounded or sometimes oblique at the base, almost
glabrous, yellowish-green above, glaucous below and usually conspicuously
purplish; petioles shorter than the blades, mostly about one-third as long,
slender; peduncles 11 mm. or less in length, usually one at each node; bracts
somewhat saccate, broudly obtuse, ciliolate, puberulent; flowers 4 mm. long or
less, rose-red; stamens included; fruit light straw-color or greenish, + mm.
long and about as wide, with 8 prominent vertical ribs on the ventral surface
and about 7 sharp, narrow, long teeth on each side, these usually not incurved,
but extended in the same plane as the body of the fruit; on the dorsal surface
of the fruit are two rows of short-pediceled glands, about 6 glands in each
row; leaves more or less wiavy-margined and the whole surface of the blade
often more or less wavy.

The deseription is based upon plants collected in the Mesilla Valley, New
Mexico, which seem well to match portions of the type collection preserved in
the Bernbardi Herbarium. The name glabra is not an especially appropriate
one,

The species is distinguished by its peculiar fruit whose wings are not in-
curved as they are in other species; whose teeth, too, are sharper and more
numerous. It is also separated by its small, obtuse, purplish and often
glaucous, undulate leaves, and by its slender stems. It is, in New Mexico
and in other places from which I have examined specimens with roots, an
annual plant, while most of the other species are perennials.

Perennial herbs, glabrous or pubescent, with the branches of the stem and
inflorescence opposite or alternate; leaves opposite, rather fleshy, entire, petioled
or sessile; flowers 1 to 5 in each involucre, white, pink, purplish red, or crimson,
surrounded by a gamophyllous, 5-lobed involucre which is enlarged and mem-
branous in fruit; perianth campanulate or infundibuliform, often oblique,
with an erect or spreading limb; stamens 2 to 5, unequal, filaments very slen-
der, united at the base; fruit club-shaped, 5-angled or 5-ribbed, pubescent or
glabrous.

The genus was based upon a plant which was later named Allionia violacea

A, glabrifolia; and Calymenia upon six species, all true Allionias, without the
designation of any one of them as the type.

STANDLEY—ALLIONIACEAE OF THE UNITED STATES. 335

The genus Allionia contains about 20 species besides those cited here. It is
best represented in the western and southwestern parts of the United States
and in Mexico; it extends into South America as far as Chile and Peru. It is
a remarkable fact that one species, A. Wimalaica, extends into the Himalaya
Mountains of Asia, the only species to be found outside the western hemisphere.
A number of species occur in Mexico which are not included in this paper
because of the inability of the author to secure reliable material of them. A
considerable number of sheets of Mexican origin were seen which were referred
by their collectors to A. violacea, A. glabrifolia, and similar species, but the
author was unable to determine them satisfactorily, the only material in whose
identity any confidence could be placed being that in the Bernhardi Herbarium.

The various species, although they do not usually cover such wide ranges as
the species of Boerhaavia, extend sometimes over rather large areas. Some
species, such as A. hirsuta and A. nyctaginea, are found almost throughout
the central-western part of the United States, while others, judging from the
material now in the various herbaria, are confined to very small areas, areas as
small as those occupied by species of Abronia. In this matter of the extent of
distribution of individual species this genus stands midway between Abronia
and Boerhaavia.

Allionin can be at once divided into two natural sections, one with flowers
whose perianths are crimson in color and have a conspicuous tube, and the
other with flowers whose perianths are purplish, pink, white, or greenish, but
never scarlet, and are campanulate in form,: It is possible that at some time
the crimson-flowered species will be found worth separating as a new genus.
They are so like the other species in habit and general appearance, however,
that the writer has thought best to leave them in the genus Allionia.

There is room for some interesting field work in this genus, especially in
order to determine the relation of the forms with axillary infiorescence to those
with panicled or cymose inflorescence. ‘The opinion has been expressed by
various persons that some of the forms with axillary flowers may be merely
depauperate or shade forms of species with more numerous flowers. A. aggre-
gata bears a very striking resemblance to A. hirsuta, A. decumbens to A. lanec-
olata, and A. bodini to A. linearis, Several other similar cases could be men-
tioned. The possibility of A. aggregata and A. hirsuta being variations of the
same plant is made more plausible by the fact that they occupy practically the
same area of distribution; the same is true in the other two instances men-
tioned. If it should be proved that one of. these pairs is related in the way
suggested—that is, that the axillary-flowered plant is merely a form of another
larger plant induced by peculiar environmental conditions—then such plants as
A. decumbens, A. aggregata, and others should, of course, take the rank of
subspecies of the species to which they are most closely related. There are a
few of the forms with axillary involucres which do not seem to be closely
related to other more complex forms, but perhaps this is because the plants to
which they are related have not yet been collected.

+. Allionia gracillima Standley, sp. nov.

Stems 20 to 50 cm. long, from a slender woody root, very slender, much
branched, dichotomous, frequently 4 branches from a single node, the branches
rather densely interlacing, the plant erect or decumbent, the stems glabrous
throughout, more or less glaucous, especially near the nodes; leaf blades thin,
linear, acute, bright green, sessile, 10 cm. or less in length; involucres single
in the axils of the leaves on filiform pedicels, which are G mm. or less. in
length, the pedicels glabrous or with a few minute, appressed hairs; flowers
apparently all cleistogamous; involucres cleft almost. to the base, the lobes
narrowly elliptical, acutish, finely pubescent, about 4 mm. high; fruit 5.5 mi.
or less in length, acutish above, slightly narrowed below with 5 very prominent
and thick, obtuse ribs, finely hispidulous,

I first saw this plant in the herbarium of the University of Arizona, but
hesitated to describe it, thinking it merely an abnormal form. Later, on ex-
amination of the excellent series of specimens of the plant collected by Mr.
Blumer, it could be seen that the plant was distinct from its nearest ally,
A. coccinea, From that species it differs in its more slender and much branched
stem, less erect habit, cleistogamous flowers, and the usually single fruit in the
involucre; the method of inflorescence, too, is very different.

Type in the herbarium of the New Mexico Agricultural College, collected in
the Chiracahua Mountains, Arizona, 1907, /. C0. Blumer 1769, near Paradise,

2a. Allionia gracillima filifolia Standley, subsp. noy.

This differs from the species in having smaller and thicker filiform leaves.
It also appears to be a smaller plant. The leaves of the species, although
harrow, are not filiform but flat. .

Type in the herbarium of the New Mexico Agricultural College, collected nt
Mangas Springs, New Mexico, August 17, 1902, Wooton.

2b. Allionia gracillima scabridata (Heimer!) Standley.

Mirabilis coccinea scabridata Heimerl, Aun. Cons. et Jard. Geney. 5: 186.
1901.

In the herbarium of the University of Arizona there is a specimen collected
in the Santa Rita Mountains, Arizona, 1903, Thornber 252, that answers well
to the description of Doctor Heimerl’s variety, in having its stem and leaves
covered with a fine appressed pubescence almost throughout. The type was
collected in the Santa Rita Mountains by Pringle. If this plant is the same
as the type, and I have little doubt that it is, it is more closely related to A,
gracillima than to A, coccinea, differing from the former chiefly in its pubes-
cence and rather wider leaves.

3. Allionia petrophila Standley, sp. nov.

Perennial from a thick root, 50 to 60 em. high; branches erect, strict: stems
sparingly branched, very slender, glabrous except the branches of the in-
florescence, which are finely and sparingly puberulent, pale or glaucous: leaf
blades linear, 75 mm. long or less, of medium texture, glabrous, acutish, ses-
sile; inflorescence dichotomously cymose, the cymes narrow, few-flowered ;
involucres on pedicels about 5 mm. long and densely soft-pubescent ; involucres
about 10 mm. in diameter, the lobes broadly ovate, obtuse, densely soft-
pubescent, the lobes as long as the tube or shorter; fruit brown, 4 mm. long,
‘ather obtuse above or acutish, narrowed below, with 5 very thick, tuberculate
ribs, the narrow spaces between the ribs tuberculate, glabrous.

habit. Type in the herbarium of the University of California (sheet 101176),

Oxrybaphus glaber S. Wats. Am, Nat. 7: 301, 1875.

On account of its glabrous fruit and stems this is a very distinct species.
The involucres are usually 1-flowered. The type material consisted of merely
a few panicles in fruit broken from the ends of the stems, but there is little
doubt about the identity of the plant.

This is an exceedingly variable species, and one that is difficult to study from
herburium material. Such muterial usually does not show the color of the
flowers, nor, what is of more importance, the habit of the plant. As it is defined
here it is probably a composite species, and some of the specimens should per-
haps even be placed in some of the closely related species. Some of the plants
are noteworthy because of their bracted inflorescence which has slender and
much jointed branches. Whether this form is worthy of separation I have
been unable to determine.

Mr. K. K. Mackenzie writes me that 1. bushii Britton, which he has seen in
its type locality, Jackson County. Missouri, is an artificial form of 1. linearis,
which grows rather commonly along the railroad tracks. When this is cut down
by the section men small, depauperate shoots spring up from the stubs that are
Jeft, and one of these was described as A. bushii,

The following collections could be referred here, if anyone cares to maintain
this form as a variety:

da. Allionia linearis subhispida (Heimerl) Standley.
Mirabilis linearis subhispida Heimer], Ann. Cons. et Jard. Genev, 5:186. 1901.
This is distinguished from the species by its stem which is more or less
hirsute throughout, the pubescence extending to the leaves. It seems to be a
smaller plant, too, and is probably a good species, but the author has seen no
very good material.

G. Allionia divaricata Rydb. Bull. Torr. Club 29: 691. 1902,

From A. /inearis this is distinguished chiefly by its long, thin, acuminate
leaves, which are also wider, and by the prominent petioles: from A. diffusa by
the less pubescent peduncles, taller and less branched stem, and the petioled
leaves; from A. glandulifera by its less branched habit, narrower and petioled
leaves, and Jess abundant and different pubescence. The species is also more
or less closely related to A. melanotricha. :

This is a plant that is very difficult to understand and determine from her-

Various authorities have stated that this is the same as A. diffusa, Tt cer-
tninly resembles that species very closely, but I do not believe that it can he
the sume. 1. glandulifera is a larger, rather more branched plant of a much
brighter green color. It also seems to be more pubescent and glandular.

Perennial from a thick, fleshy root about 18 mm. thick or less; stems few
from each root, rarely more than 2. 35 cm. or less in height, very slender, sim-
ple or very sparingly branched, glabrous below, very minutely soft-puberulent
above; leaves sessile, narrowly linear, thin, 65 mm, long and 3 mm. wide or
less, sharp-pointed, glabrous, divaricate or asc ending; inflorescence axillary or
of small, loose, terminal, few-flowered cymes; involucres on pubescent pedicels &
mm. long or less; upper leaves sometimes reduced to bracts; involucres 8 min.
wide and 6 mm. high or less, the lobes elliptical or oblong, obtuse, rather densely
soft-puberulent: flowers apparently all cleistogamous: fruit 3.5 mm. long, in-

Plant low, 20 cm. high, erect, abundantly dichotomous-branched, especially
near the base; stems angled, at least when dry, glabrous below, with a few
scattered, weak hairs above; leaf blades linear-lanceolate, thin, blunt-pointed,
rounded, cuneate, or attenuate at the base, the margins very irregular and with
a few conspicuous long, soft, white hairs, a few such hairs seattered over the
surfaces of the leaves as well; petioles 7 mm. long or less, with a few hairs
like those on the blades; inflorescence axillary or a few of the involucres
clustered at the ends of the branches; involucres short-pediceled, the pedicels
rather densely long-pubescent, not at all viscid: involucres about 10> mm.
wide and 8 or 9 mm. high, the lobes about as long as the tube, acutish, sparingly
puberulent or glabrous, ciliolate-margined; fruit + mim. long, brown, rather
obtuse above, slightly narrowed below, 5-ribbed, the ribs thick and more or
less tuberculate, the narrow spaces between them also tuberculate, glabrous.

15, Allionia pumila Standley, sp. nov.

Plant low, about 12 cm. high, much branched from a thick, woody root, the
stems sparingly branched: stems rather slender, densely soft-pubescent; leaf
blades ovate or oblong, small, 25 mm. long and 16 mm. wide or less, obtuse
or rounded at the apex, rounded or mostly somewhat attenuate at the base,
rather thick but soft, finely puberulent on both surfaces, yellowish-green : peti-
oles slender, pubescent, mostly as long as the blades or longer, some of the upper-
most a little shorter: involucres solitary in the axils of the leaves, drooping on
short, densely pubescent pedicels; bracts ovate, obtuse, densely soft-pubescent,
10 mm. or less in diameter, about 5 to 6 mm. high; fruit not seen,

A very distinet species on account of its low, dense habit, finely pubescent
stems, and long petioles. It is as closely related to A. aggregata as to any
species, but is different in habit and pubescence. Doctor Heimer! in the National
Herbarium has labeled it A. pilosa (A. Gray) (A. comata Small), but the
latter is a much larger plant with quite different inflorescence. Type U. 8.

16. Allionia brandegei Standley, sp. noy.

Perennial from a very thick and woody root; stems many from each root,
18 em. high or Jess, erect or spreading, viscid-pubescent throughout, densely so
above; stems mostly simple, sometimes sparingly branched; leaf blades lanceo-
late, 35 mm. long and 14 mm, wide or tess, thick, densely viscid-puberulent on
both surfaces, attenuate toward the apex, cuneate or attenuate at the base;
petioles one-half as long as the blades or usually less, those of the uppermost
blades very short, densely viscid-pubescent; involucres few, axillary, not
more than 1 at any single node, about 18 mm. in diameter and 10 mm. high,
the bracts ovate or triangular-ovate, acute, longer than the tube, densely
puberulent within and without, thick; fruit G mm. long, dark olive, acutish,
with 4 or 5 low, more or less tuberculate ribs, the spaces between the ribs also
tuberculate, very sparingly puberulent, some of the fruits even glabrous;
flowers not seen but probably cleistogamous,

This is most like A. pumila, but its leaves are thicker and more densely
pubescent and of a different shape, the petioles shorter, and the lobes of the
involucre more acute. Type in the herbarium of the University of California
(no. 10164), collected in the Providence Mountains, California, June 2, 1902,
Brandegee. Purpus’s 5905 from Highland Peak, Nevada, seems to be a glabrate
form of this: aside from its less abundant pubescence it does not seem to
differ, and is probably merely an older plant.

17. Allionia pachyphylla Standley, sp. nov.

Low, 30 em. high or less, from a woody root; stems stout, much branched,
with short internodes, low and more or Jess spreading; stems with abundant,
‘ather hispid pubescence throughout; leaf blades ovate, obtuse, truncate, or
subcordate at the base or sometimes attenuate, thick, more or less puberulent
on both surfaces, paler beneath; petioles of the lowest leaves almost as long
as the blades, becoming shorter above, the uppermost leaves almost sessile,
the petioles stout; inflorescence subcymose, of few branches, the branches
with conspicuous, broadly ovate, thick bracts, densely pubescent; involucres
on short, densely pubescent pedicels, about 1 cm. in diameter, their lobes
ovate and densely pubescent; fruit 5 mm. long, acutish above, prominently
5-ribbed, very finely puberulent.

A very distinct species referred to A. pilosa (Gray), from which it is quite
different in habit; its leaves, too, are much thicker, and the fruit more acute.

Krect from a rather thick and woody root; stems sparingly branched, stout,
hirsute below, the branches of the inflorescence soft-pubescent; leaf blades
ovate, the uppermost rather narrowly so, thick, glabrous or sparingly pilose,
obtuse or rounded at the apex, rounded or truncate at the base, large, 7 em.

densely soft-pubescent; fruit clavate, minutely strigose, rather obtuse above, 4
or 5 mm. long.

This is not likely to be confused with any species except A. pachyphylla,
It is distinguished from that species by its larger leaves and hirsute pubes-
cence; the stem, too, is less branched. Type in the herbarium of the University
of California (no. 101182) collected at Canyon City, Colo,, August 13, 1872,

20. Allionia rotata Standley, sp. nov.

Plant probably tall (there are only the ends of branches upon the sheets) ;
stems sparingly puberulent throughout but not viscid, almost glabrous below,
sparingly branched, the branching mostly dichotomous; leaf blades ovate,
obtuse, cordate at the base, glabrous or the uppermost more or less puberulent ;
petioles very short, the uppermost leaves sessile; inflorescence subcymose, its
branches slender and covered with much reduced, bract-like leaves; involucres
on slender pedicels 7 mm. long or less, when mature circular in outline or
scarcely lobed, sparingly soft-puberulent, about 25 mm. in diameter, ciliolate;
fruit 4 mm, long, much narrowed below, obtuse above, 5-ribbed, prominently
transversely ridged or tuberculate, glabrous or minutely puberulent.

From A. viscosa the plant is distinguished by its less pubescent and not
viscid stems and leaves, shorter petioles, alternate branching, and more tubercu-
Inte fruit. The plant has also 2 or 3 flowers and fruits in each involucre while
A. viscosa has uniformly only one. Type in the herbarium of the Missouri
Botanical Garden, collected at Azufrora near Saltillo, Mexico, September 22,
1848, Gregg 511.

21. Allionia coahuilensis Standley, sp. nov.

Stems stout, erect, about 1 meter high, pale below, darker above, with more
or less abundant, short, soft pubescence below which becomes more dense above:
leaf blades lanceolate, 50 mm. long and 17 mm. wide or less, cuneate or rounded
at the base, blunt-pointed, of medium thickness, densely soft-pubescent on both
surfaces, the margins irregular, all leaves except those of the inflorescence
with conspicuous petioles 20 mni. long or less; inflorescence paniculaite, its
branches stout, opposite, very densely viscid-pubescent throughout, the hairs
‘ather long and spreading; branches of the inflorescence with conspicuous.
much-reduced, bract-like leaves, these 5 mm. long or less, ovate, densely viscid-
pubescent ; involucres 12 mm. wide or less and about S min, high. glandular-
villous, on short glandular-villous, often bracted pedicels; lobes of the involucre
broadly ovate or orbicular, broadly obtuse, short; fruit 4 mmm. long, obtuse above,
slightly narrowed below, with 5 smooth, rather prominent ribs, the spaces
between them transversely rugulose and hirtellous,

This somewhat resembles A. pseudaggregata, but is a larger plant, with
pubescent stems and more densely pubescent inflorescence, the pubescence being
also of a different character; the leaves, too, are prominently petioled, while
those of A. pseudaggregata are mostly sessile, and the inflorescence is paniculate
‘uther than dichotomously branched as it is in the latter species. Type in the
herbarium of the University of California, collected at Saltillo, Coahuila,
Mexico, 1898, Palmer 158.

22. Allionia greggii Standley, sp. nov.

Stems erect, rather slender, more or less subhirsute below, densely glandular-
pubescent above, the branching dichotomous; leaf blades lanceolate or lance-
ovate, mostly blunt-pointed but some of them acutish, rounded or cuneate at the
base, glabrous; petioles one-half as long as the blades, sparingly subhirsute, the
uppermost leaves sessile: inflorescence congested, subcymose; involucres short-
pediceled, the lobes ovate, acute, densely covered with matted hairs, 3-flowered ;
fruit 4 mim. long, with 5 thick but low ribs, not tuberculate, sparingly puberulent.

The smooth and puberulent fruit, obtuse and narrower leaves which are not
cordate at the base, and $-flowered involuecres separate this from A, glebri-
folia, From A. pscudaggregata it is readily distinguished by the blunt, petioled
leaves and more pubescent stem. Type in the herbarium of the Missouri: Botan-

Stems erect, simple below or sparingly branched, very stout and tall, probably
considerably over 1 meter in height, softly dappressed-puberulent throughout ;
leaf blades thick, the lower ones large, 10.5 ecm. long and 8 cm. wide or less,
broadly ovate, obtuse, truncate at the base, almost sessile; the upper leaves
oblong, 8.5 cm. long and 4.5 em. broad or less, obtuse, broadly cuneate or
rounded at the base, prominently veined, short-petioled, the uppermost ones
sessile; inflorescence paniculate, its branches opposite: involueres on pedicels
10 mm. long or Jess, 10 mm. wide, and about 7 mm, high, the lobes broadly ovate,
obtuse, densely and finely puberulent; flowers about 10 mm. long, the stamens
slightly exserted; fruit 5 mm. long, 5-ribbed, the ribs tuberculate, the spaces
between them puberulent, acutish above, somewhat narrowed below.

The large size, thick and peculiarly seen leaves, small involucres, and
pubescent stem separate this plant from A. floribunda and A. nyctaginea, to
which it is most closely related. Type wna duplicate in the herbarium of the
Missouri Botanical Garden, collected in Texas, on sands at Buzzards Spring,
August 1, 1902, Reverchon. It was also collected by the same collector on sinds
at Handley, October 38, 1902.

Tracy's 8342 from Weatherford, 1902, seems to be the same plant at a more
mature stage; its involucres are larger, about 16 mm. wide and 10 min. high.
The plant is rather smaller, but it has the peculiar leaves and pubescent stems
of the type,

In the herbarium of the Missouri Botanical Garden there is a sheet of this

It is barely possible that this may be one of the specimens from which the plant
was first described, for this is the locality given with the original description.

It is questionable whether this should be maintained as a species or reduced
to a variety of A. nyctaginea; both treatments have been given it by various
authors. The northern plant, the typical form, seems to vary from A. nycta-
ginea principally in the shape of the leaves, certainly not a very good specific
difference. In Texas, however, shading gradually into the northern form, there
is a plant which is very different from A. nyctaginea, Not only are its leaves
different in shape, but the plant is much more slender in every part, and
there are other differences. This plant, I think, certainly deserves specific rank,
and it is so closely related to A. floribunda that IT have thought it better to
include it here under that name rather than give it a new name.

29. Allionia pratensis Standley, sp. noy.

Root perennial, long and slender; stems much branched from near the base,
sparingly dichotomous above, erect or ascending, about 40 cm. high, more or
less densely subhispid or subpilose throughout, the uppermost branches densely
so, the hairs more scattered below; leaf blades deltoid-ovate to broadly lanceo-
late, 4.5 cm. long, 8 cm. wide or less, obtuse or the uppermost acute, the lower
ones glabrous, the upper more or less pubescent; petioles as long as the blades
or longer, the uppermost blades sessile; inflorescence cymose, rather dense, its
branches densely puberulent; involucres on pedicels 10 nim. long or less, about
9mm. wide and 7 mim. high or less, the lobes elliptical or ovate, obtuse or acutish,
densely covered with rather long, soft, pale hairs, the free portion as long as
the tube or longer; perianth about 12 mm. long and 17 mm. wide, rose-purple;
stamens 5, exserted: fruit 4 mm. long, obtuse, 5-ribbed, the ribs low and almost
smooth, the spaces between them smooth and minutely hispidulous.

Although rather closely related to A. melanotricha, this plant seems amply dis-
tinct. Its flowers are broader, the stamens more numerous, the pubescence much
more abundant, the petioles longer, the leaves broader and more numerous, the
plant lower and lacking the black hairs found upon the involucres of the latter
species. Type in the herbarium of the New Mexico Agricultural College, col-
lected at Barfoot Park, in the Chiracahua Mountains, Arizona, L907, Blumer

Stems erect, abundantly dichotomous-branched, about GO cm. high, glab-
rous except the branches of the inflorescence, these rather closely covered
with moderately stiff, rather spreading viscid pubescence; leaf blades lance-
olate, 8 cm. long and 38 em. wide or less, bright yellowish-green, attenuate
at the apex, broadly cuneate or rounded at the base, glabrous except the
sparingly ciliolate margins; petioles one-half as long as the blades or shorter,
those of the uppermost leaves very short; inflorescence cCymose; involucres
numerous on short, densely pubescent pedicels, not more than S mim. broad
and 6 mm. high, densely covered with short, soft hairs, these light-colored
along the margins of the lobes but black elsewhere, the lobes oblong, rounded ,
at the apex, twice as long as the tube; flowers about 16 mm. long and 12 mim.
wide, bright rose-purple; stamens 8, exserted; fruit about 3 mm. long, with
+ or 5 narrow, tuberculate ribs, the smooth surfaces between them sparingly
puberulent.

Docter Heimer] in his notes which are attached to the sheets in the National
Werbarium has called this A. oblongifolia, but the specimens of the type
collection of that species in the National Herbarium «and the Missouri Botanical
Garden are of very different plants. The two differ in the form of the leaves,
in their pubescence and their inflorescence, and in the size of their involucres,

With regard to this and the preceding species, Mr. Blumer writes: " Nos,
147 and 148 are perfectly distinct in the field, though collected within a stone’s
throw of each other—you need have no hesitancy about that. The new one
(A. pratensis) is a cespitose plant and the flowers open wider. That the
flowers are larger and the leaves very different you can see by the specimens.
in all of my Barfoot Park specimens [ made it a point, if possible, to represent
in my gathering the range of variation of the species, and [ remember that in
this case there was no suggestion of intergrades.”’

of the uppermost blades ovate, mostly obtuse or rounded at the apex, rounded
at the base, the lower ones with short but distinct petioles, the upper sessile,
soft-pubescent or pilose on both surfaces or sometimes almost glabrous, thin and
soft, the leaves spreading; inflorescence panicled, its branches opposite and soft-
pubescent, leafy, the reduced leaves oblong and rounded at each end, the
branches with many glandular hairs among the pubescence; involucres on
pedicels 10 mim, long or less, about 12 mim. in diameter and 7 mim. high, the
lobes ovate, obtuse, soft-pubescent; flowers 10 mm. long, rose-purple; stamens
3, scarcely exserted, the style long-exserted; fruit 4 mm. long, rather obtuse,

Allionia hirsuta rotundifolia Lunell @ seems to be a form of this species. It
uppears to be a depauperate state, produced, probably, in the same way
as A. bushii.

35. Allionia chersophila Standley, sp. nov.

Stems erect, tall, 1 meter high or even more at times, stout, simple below or
sparingly branched, densely soft-pubescent throughout, not glandular above;
leaves linear-lanceolate, rather thick, sessile, blunt-pointed, tapering to the base,
more or less soft-puberulent ou both surfaces, especially beneath: inflorescence
ample, paniculate, branches opposite; involucres on pedicels 10 mm. long or
less, 15 mm, broad, and 10 mm. high or less, the lobes broadly ovate, obtuse,
sometimes mucronate, densely soft-pubescent; fruit 5 mm. long, narrow, acute,
narrowed below, with 5 conspicuous ribs, these almost smooth, the spaces be-
tween them finely tuberculate, minutely hispidulous.

This is perhaps as closely related to A. pilosa as to any species, but is readily
separated by its denser and softer short pubescence and stouter habit. Type
in the herbarium of the University of Wyoming, cotype in that of Mr. K. K.
Mackenzie; collected in barrens at Lees Summit, Jackson County, Missouri, Sep-
tember 9, 1901, Maekenzie 421; also collected in Jackson County, 1891, by Mr.
BR. I’. Bush, who says that the plant is rare.

36. Allionia trichodonta Standley, sp. nov.

Stems erect or ascending, sparingly branched, the branches alternate, slender,
rather sparingly puberulent throughout or almost glabrous below: leaf blades
linear or linear-lanceolate, 45 mm. long and 7 mm. wide or less, of medium
thickness, attenuate to the apex and to the base, sessile, the margins Wavy and
ciliolate, with a few long, weak hairs on both surfaces; inflorescence narrowly
cymose, its branches densely short-villous; involucres almost sessile or some-
times pediceled in the axils of the lower leaves, 11 mm. in diameter or less,
densely short-villous, the pubescence having a silky appearance, especially on
the margins of the lobes, these elliptical or lanceolate, acute or acutish ;
flowers not seen; fruit 4 mm. long, rather obtuse above, slightly narrowed
below, with 5 very thick, smooth ribs, so thick that there are scarcely any
spaces between them, minutely hispidulous.

Distinguished from A. codhuilensis and A. pseudaggrcgata, its nearest allies,
hy its narrower leaves and bracts and the thicker ribs of the fruit: from A.
codhuilensis Dy its alternate branching, and from A. pseudaggregata by its
more pubescent stems. Type in the herbarium of the University of California
(no, 101379), collected at Ixmiquilpan, Hidalgo, Mexico, 1905, Purpus.

37, Allionia carletoni Standley, sp. nov.

Plant about 1 meter high; stems simple below or more or less branched,
stout, whitish, soft-pubescent throughout; leaf blades lanceolate, very thick,
acutish, somewhat wavy-margined, conspicuously veined, rounded or cuneate
at the base, 7 cm. long and 3 cm, wide or less, puberulent on both surfaces,
almost or quite sessile; inflorescence paniculate, the branches mostly opposite,
stout, open; involucres about 15 mm. in diameter, the lobes rounded or obtuse
and short, with rather copious soft pubescence, ciliolate; involucres on pedicels
about 10 mm. long, the pedicels subtended by very small and inconspicuous
bracts: fruit 5 mm. long, acutish above, narrowed below, with 5 prominent
smooth ribs, the spaces between the ribs each with a single vertical row of
tubercles; fruit glabrous, ,

Easily distinguished by the glabrous fruit and the fine, short pubescence of
the stems. Type U. 8. National Herbarium no, 22755, collected in Barber

The specific name was adopted from Doctor Heimerl in herbarium under
Mirabilis.

38. Allionia exaltata Standley, sp. nov.

Plant about 1.5 meters high from a rather thick, woody root; stem little
branched below, glabrous throughout, glaucous, stout below, but slender above;
lenf blades rather narrowly lanceolate, 70 min. long and 18 mm. wide or less,
neutish, attenuate at the base to a very short, thick petiole, or sessile, more
or less wavy-margined, glabrous; inflorescence very openly paniculate, its
branches slender and opposite; involucres on pedicels mostly about 10 mim.
long, mostly glabrous or with a very few minute hairs; involucres 15 mm. in
diameter. their lobes broadly ovate and rounded, glabrous or with a few
minute hairs when young; fruit obtuse or acutish above, narrowed below,
rugulose between the ribs, prominently 5-angled, glabrous.

This is u more slender plant than A. carletoni, and is probably ordinarily
tnller. It is readily separated from that species by its glabrous stem and
leaves, the latter also being narrower. Type U. 8S. National Herbarium no.

Irom the species this differs in its stouter habit, thicker aud more erect
leaves, 1-fruited involucres (there are sometimes 3 flowers in the involuere, but
only one matures), and the form of the fruit. The fruit of the species is merely
faintly angled, acutish above, minutely hispidulous, and not very prominently
tuberculate, while that of subspecies uniflora is larger, with 5 prominent and
thick ribs, strongly transversely ridged or tuberculate between the ribs. and
more densely and more prominently hispidulous as well as more obtuse above.

Quamoclidion Choisy in DC. Prod. 137: 429. 1849.

Perennial herbs, erect, branched, glabrous or pubescent; leaves opposite,
entire, thick, petioled or sessile; flowers mostly large, several together sur-
rounded by a gamophyllous, calyx-like involucre; perianth showy, corolla-like,
with a tube of medium length, which is expanded into a wide or rather narrow,
erect, or spreading limb; stamens 5, exserted; fruit hard, smooth, ellipsoidal
to almost spherical, glabrous.

The genus was founded by Choisy upon two species: The first, which is to
be taken as the type, he called Q. nyctagineum, of which Mirabilis triflora
Benth. was said to be a synonym; the second species was called Q. angulatum,
and was referred doubtfully to the genus. Doctor Rydberg, in his treatment
of the Rocky Mountain Allioniaceae. placed Orybaphus laevis Benth. in the
genus, a plant which differs so widely from the type species in several respects
that it has been placed in a new genus in this work,

83a. Quamoclidion multiflorum glandulosum Standley, subsp. nov.

Stems stout, rather abundantly glandular-puberulent throughout; leaf blades
ovate, thick, acutish, rounded or subcordate at the base; petioles about one-
third as long as the blades, glandular-puberulent; peduncles stout, densely
glandular-puberulent, 2 cm. long or less: bracts about 2 cm, long, the free
portion a little longer than the tube, obtuse or acutish, densely glandular-
puberulent; flowers 4 em. long or less; leaves a-rather light yellowish-green,

This subspecies is distinguished by its yellowish-green, puberulent leaves, ¢glan-
dular stem, and puberulent, obtuse bracts. Type in the National Herbarium,
cotype in the Missouri Botanical Garden, collected in Colorado on a dry mesa
at Grand Junction, May 28, 1894, Crandall 423, altitude 1575 meters. There
is no mature fruit on either of these specimens, but a plant in the Rocky
Mountain Herbarium that seems to be the same, collected at Deer Run, Colo-
‘ado, 1901, C. F. Baker S81, has fruit elliptical or oblong-elliptical in outline,
about 9 mm, long, dark reddish brown in color, obscurely 10-nerved, glabrous,
This last plant has rather thin and almost scarious reddish bracts,

Other specimens examined:
CoLoraAbo: Mancos, 1890, Kastiwood; Grand Junction, 1894, Jones 5476,

Baker's 304 from Rosa, New Mexico, is probably the same, although it does
not match the type in all particulars.

2b. Quamoclidion multiflorum obtusum Standley, subsp. nov.

Stems rather slender, with short, rather viscid pubescence throughout which
consists of flattened, white hairs: leaf blades very broadly ovate or almost
reniform, thin, bright green, almost glabrous, broadly obtuse and apiculate at
the apex, semicordate to rounded at the base, the blades somewhat decurrent
upon the petiole which is half as long as the blade or shorter; bracts broadly
ovate, acutish, apiculate, about 3 em. long and 15 mm. wide, the free portion
one-half as long as the tube or longer. bright green; flowers like those of the
species.

Distinguished by the large and broad bracts and especially by the shape
of the leaves. Type in the herbarium of the University of Wyoming, col. -
lected on rocky ledges at Kernan, Nevada, 1902, Goodding 658, The plant is
covered with what appears to be the web of some insect, giving it a peculiar
woolly appearance,

The following plants should probably be placed here, although they have
thicker leaves and the leaves are not acuminate. They have dark-colored
fruits, showing that they are more closely related to Q. multiflorian than to
Q. froebelii, They with the subspecies glabratum of the latter species form a
close transition between the two species.

Hesperonia Standley, gen, nov.

Mirabilis of various authors, in part, not L.

Quamoclidion Rydb. Bull, Torr, Club 29: 686, in part; not Choisy.

Perennial herbs; leaves opposite, thick, entire, petioled or sessile; inflorescence
axillary or terminal; involucres campanulate, composed of 5 bracts which are
united by their bases for about half their length, not enlarged in fruit: flowers
1 in each involucre; perianth campanulate, white or purplish red: stamens
usually 5, distinet; fruit ellipsoidal or spherical, not angled or ribbed, smooth
or sometimes very faintly tuberculate, glabrous,

The plants of this proposed genus have been variously placed in Mirabilis,
Quamoclidion, and Oxybaphus, to all of which the genus is closely related,
But besides differing considerably from all those genera in general appearance,
Hesperonia is separated from Allionia and Mirabilis by the form of the
fruit, differs decidedly from Mirabilis and Quamoclidion in the shape of the
perianth, and is separated at once from Quamoclidion by the number of flowers
in the involucre,

2. Hesperonia aspera (Greene) Standley.

Mirabilis aspera Greene, Erythea 4: 67. 1896,

Stems stout, dichotomously branched, roughly retrorse-pubescent, leaf blades
ovate, subcordate, thics, rough-puberulent, 25 mm. long and 18 mm. wide or
less, obtuse or the uppermost ones subacute; petioles very short, some of the

bracts.

LOWER CALIFORNIA: Signal Mountain, Colorado Desert, 1901, Brandegee.

In the national herbarium there are two sheets of a Hesperonia labeled
Mirabilis tenuiloba, collected in the Colorado Desert, 1889, by W. G. Wright.
This is the type locality and the collector is the same as the collector of the type.
I am not certain, however, that these belong to the type collection. The plant is
hardly separable from H. californica except that it has narrower bracts. If
this is H. tenuiloba, and it answers to the brief original description about as
well as the plants I have listed under that name, the others should have a new
name, for they are certainly not the same as these plants of Mr. Wright’s.

4. Hesperonia laevis (Benth.) Standley.

Ozrybaphus laevis Benth. Bot. Voy. Sulph. 44. 1844.

Mirabilis laevis Curran, Proc. Cal. Acad. Sci. II. 1: 235. 1889,

_ In the herbarium of the University of California there is a specimen of what
I take to be this species, collected at the type locality, Magdalena Bay, Lower
California, by Doctor Lung, U. 8. N., no. 28. The plant has no fruit, but other-
wise the characters can be determined fairly well, although the specimen is not
of the best.

Branches dichotomous, straight, perfectly glabrous, rather slender, with long
internodes; leaf blades ovate, somewhat sinuate-margined, rather thin, acutish:
leaves 30 mm. long and 20 mm. wide or less, the uppermost considerably smaller ;
petioles almost as long as the blades in the lowest leaves, the uppermost blades
almost sessile; leaves glabrous; flowers single in the axils of the leaves or
apparently clustered at times at the ends of the branches; bracts mostly 10 mm.
long, the free portion as long as the tube or longer, the segments lanceolate,
acute, glabrous, or with a very few minute, appressed hairs; flowers about 16
mm. long.

‘The type was described as glabrous, and it seems quite probable that this is
the same plant as the one collected at the same place during the voyage of the
Sulphur. It is the only quite glabrous plant that I have seen in the genus.

5. Hesperonia oligantha Standley, sp. nov.

Stems branching from a woody base, the lower branches suffrutescent; stems
slender, very closely and sparingly puberulent or almost glabrous; internodes
25 to 50 mm. long; leaf blades ovate, subcordate at the base or rounded or
rarely somewhat narrowed, thin, sparingly puberulent, with prominent lateral
veins, the lower leaves obtuse, the upper ones acute; petioles one-third as long

364 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

as the blades; flowers on peduncles almost as long as the involucre; bracts
lanceolate, acute, the free portion as long as the tube, finely and densely
puberulent, the whole about 9 mm. long; flowers about 12 mm. long, the stamens
long-exserted ; fruit cylindrical; acutish at both ends, dark brown, smooth, T
or 8 mm. long, and almost 38 mm. thick.

From H, polyphylla this differs in its obtuse lower leaves, which nre some-
times cordate at the base, thinner blades, less pubescent stem, longer and nar-
rower fruit, and fewer flowers; from //. tenuiloba, in its more slender stems,
obtuse lower leaves, thinner blades, and longer and narrower fruit. Type in the
herbarium of the University of California, collected at Calmalli, Lower Cali-
fornia, 1898, Purpus 82.

6. Hesperonia polyphylla Standley, sp. nov.

Perennial; much branched from a woody base, the lower branches suffrutes-
cent; stems stout, glabrous below, finely short-pubescent above, not viscid, the
nodes swollen and conspicuous, the internodes short: leaf blades ovate, acute,
rounded at the base, glabrous or the younger ones sparingly puberulent, thick
and fleshy, the lateral veins inconspicuous; blades small, less than 20 mm. long
and about 10 mm. wide; petioles not more than one-third as long as the blades,
stout; most of the flowers on peduncles which are about as long as the invo-
lucre; bracts lanceolate or ovate-lanceolate, the free portion about as long as
the tube, the whole about 9 mm, long, thick and puberulent: flowers about 2 em,
long and almost as wide; the stamens included; fruit oblong in outline, broadly
obtuse at both ends, smooth, brown, about 4 mm. long and almost 8 mm. wide.

From i. tenuiloba this differs in the smaller size of the plant, shorter inter-
nodes, more leafy appearance of the plant, smaller and thicker leaves which
are not cordate at the base, and the broader segments of the involucre. The
internodes near the ends of the branches are very short, so that the branches
are densely leafy; there is a flower in almost every axil and at least one at each
node, so that the flowers appear numerous. Type in the herbarium of the
University of California, collected at San Borga, Lower California, May 6, 1889,

A plant in the herbarium of Nevada State University collected at Highlands,
San Bernardino County, California, 1904, by N. KX. Berg, is an interesting form
with long-petioled leaves which are rounded and cordate at the base and some-
times reniform in outline, and with stout, suffrutescent stem.

7a. Hesperonia californica microphylla Standley, subsp. nov.

Much branched from 2 woody base, the lower branches woody and whitish,
glabrous, the internodes short, the nodes large and swollen; leaf blades irreg-
ularly ovate or deltoid-ovate, obtuse or acutish, mostly semicordate at the base,
thick, 15 mm. long and 8 mm. wide or usually less; petioles about half as long
as the blades; branches of the inflorescence slender, not much branched, 2 or
sometimes more flowers at each node, the flowers on short pedicels which are
sparingly scabrate; flowers about 11 mm. long; stamens included; bracts 4 or
5 mm. long, the free portion rather narrowly triangular, acute, a little longer
than the tube or as long; fruit elliptical in outline, 4 mm. or less in length,
dark brown.

Type in the herbarium of the University of California (no. 101214), collected
by Brandegee on San Martin Island, Lower Californin, Mareh 12, 1897. Also

Mirabilis retrorsa Heller, Muhlenbergia 2: 198. 1906.

I can not see how this can be separated from HH. glutinosa except as a sub-
species. It differs from that species in having narrower and more acute leaves
and less abundantly pubescent stem; but aside from these minor differences I
ean see little to separate the two plants.

37 mm. wide or less, rather thin, obtuse or broadly rounded at the apex, semi-
cordate or rounded at the base, more or less puberulent on both surfaces, except
the oldest blades, which are sometimes quite glabrous; petioles about one-third
as long as the blades, villous; inflorescence slender, few-flowered, the separate
flowers almost sessile; bracts 5 or 6 mm. long, lanceolate or narrowly triangu-

fruits subelliptical, narrowed at both ends, brown marked with transverse darker
inarks.

Type U. S. National Herbarium (no. 212108), collected in Sabino Canyon,
Arizona, 1892, Toumey 471c. The plant is distinguished by its villous pubes-
cence and slender stems.

Other specimens examined:
ARIZONA: Tempe, 1896, Towmey, not as villous as the type; Arizona, 1876,
Palmer, 644, not typical, but with the villous pubescence; Hardyville,

The label states that the last-cited plant is from New Mexico, but it is prob-
ably incorrect. No specimen of any species of the genus has been found in
New Mexico at any other time so far as the author is able to learn,

2a. Mirabilis jalapa volecanica Standley, subsp. nov.

Stems rather slender, strongly angled when dry, with rather soft pubescence
throughout; leaf blades ovate or narrowly ovate, rather acuminate at the
apex, subcordate or rounded at the base, with prominent pubescent veins,
35 to 70 mm. long and 25 to 45 mm. wide; petioles 1 cm. long or less; inflor-

368 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

This differs from the species in its narrower, thinner leaves, which are
attenuate at the base, longer petioles, more slender stems, and pubescent
fruit; from subspecies volcanica in its different leaves, longer petioles, tuber-
culate fruit, and more slender stems. Type in the herbarium of the Univer-
sity of California; collected at Culiacan, Sinaloa, Mexico, September 17, 1904,
Brandegee.

2c. Mirabilis jalapa lindheimeri Standley, subsp. nov.

Stems rather slender, glabrous; leaf blades broadly deltoid-ovate to ovate,
thin, short-acuminate or acute, truncate, rounded, or narrowed at the base,
the blades always slightly decurrent upon the glabrous, slender petioles, which
are usually half as long as the blades or longer; involucres in clusters of
about 3, or sometimes solitary, mostly pediceled; bracts lanceolate-ovate,
minutely puberulent, not usually ciliolate, the free portion about as long as
the tube; flowers about 5.5 em. long; limb about 2.5 em. wide, with prominent
rounded lobes, the tube almost or quite glabrous; stamens about as long as
the perianth; fruit about 10 mm, long and 5 mm. thick, ovoid, with 5 incon-
spicuous, broad ribs, not angled, smooth, not tuberculate, pubescent with
fine, short, soft, yellowish, appressed hairs.

This can at once be distinguished by its broad leaves. Its pubescent fruit
Separates it from the species, and its longer petioles and glabrous stem from
subspecies volcanica. Type in the herbarium of the Missouri Botanical Gar-
den, collected at New Braunfels, Tex., June, 1846, Lindheimer.

2d. Mirabilis jalapa ciliata Standley, subsp. noy.

Stems slender, abundantly furnished with fine, soft pubescence which is
almost villous, the pubescence especially abundant on the voung stems; leaf
blades ovate, subacuminate, oblique at the base, about 11 cm. long and 6 em.
wide or less, thin, glabrous above, more or less puberulent below, all con-
spicuously ciliate along the margins, the hairs soft and tawny; petioles short,
25 mm. long or less; flowers sessile or short-pediceled: bracts 12 mm. long
or less, ovate, short-acuminate, ciliolate: flowers about 55 mm. long, their
tubes rather thick, the limb about 30 mm. broad; fruit (immature) in shape
like that of M/. jalapa, tuberculate, finely pubescent.

The most striking characteristic of the plant is found in the ciliate leaves and
bracts. Type in the herbarium of the Missouri Botanical Garden, collected

2. Acleisanthes acutifolia Standley, sp. nov.

Perennial from a woody base; stems rather slender with minute and seattering
pubescence composed of short, appressed, blunt, white hairs and, scattered
among them, 2 few short, gland-tipped hairs; leaf blades lanceolate or ellip-
tical, 4.5 em. or Jess in length and J8 mm. or less wide, acute, narrowed to
the base and somewhat decurrent upon the petioles, which are one-third or
less as long as the blades, the margins wavy, both surfaces .very sparingly
puberulent; flowers short-pediceled, the pedicels about 3 mm. long; involucral
bracts 8, linear, as long as the fruit or longer; flowers funnelform, 4 cm. long
or more, rather densely puberulent without, the limb about 18 mm. wide; sta-
mens 5, exserted; some of the flowers cleistogamous, their undeveloped peri-
anths with 5 small stamens; fruit 7 to 8 mm. long, oblong, with 5 thick, smooth
ribs separated by very shallow and inconspicuous depressions; ribs ending in
small, knoblike bodies detached from the ribs proper by shallow depressions, the
latter containing small glands.

The acute leaves with narrowed bases and short petioles will separate this
plant from A. wrightii, with which it has been confused; it is also distinguished
by its different fruits, pedicels, and bracts. In A. wrightii the glands are
located at the very ends of the ribs instead of in depressions below their sum-
mits, as in this species. Type in the National Herbarium (no, 155669), col-
lected at Maxon’s Spring, Texas, by Havard. Also collected in the Santa
Eulalia Mountains, Chihuahua, 1885, Pringle 671 (plant with rather shorter
perianths and shorter pedicels than the type).

northwest,

Attached to his no. 355 in the herbarium of the Missouri Botanical Garden is
the following interesting note by Doctor Gregg regarding this plant: “ Yerba
santa (or yerba de la rabia) ; the root in a decoction is used for cholera, fevers,
ete. Said to have acquired the name of yerba santa (holy herb) in 1814 on ac-
count of its wonderful virtues in curing a plague of that year.”

4a. Acleisanthes longiflora hirtella Standley, subsp. nov.

Stems hirtellous throughout; leaves like those of the species, but broader
and not attenuate, more or less puberulent on both surfaces, thick; otherwise
like the species; “flowers white,” the perianth more puberulent than in the
species. ;

Type in the herbarium of the Missouri Botanical Garden collected near
Saltillo, Coahuila, Mexico, September 20, 1848, Gregg 463. Gregg’s 725 from
“highlands near Patos” is probably the same; it has, however, very small
leaves, and the collector says of it “ flowers scarlet; a small shrub.”

13. COMMICARPUS Standley.

Commicarpus Standley, gen. nov.

Boerhaavia l., in part.

Perennial plants with long and slender, climbing or reclining stems; leaves
thin, mostly ovate-cordate, with conspicuous petioles, entire, opposite; flowers
in umbels on moderately long pedicels; perianth short-funnelform, with a very
short tube below the broad limb; flowers small; stamens exserted; fruit rather
obscurely 10-ribbed, clavate, with numerous, rather large, mucilaginous glands
scattered over its surface.

The plants included here have always passed as Boerhaavias, but they differ
widely from the plants of that genus in the habit of the plant, form of the
fruit, and shape of the perianth. Boerhaavia scandens and several related

This closely resembles C. scandens in general appearance. The flowers, how-
ever, are much larger, 8 to 10 mm. in diameter and much longer than the small
ovary; the pedicels are pubescent instead of glabrous; the leaves are distinctly
mucronate or apiculate, and the fruit has mucilaginous glands which form hori-
zontal bands about it instead of being scattered irregularly as in C. scandens,

are more slender; the pedicels are glabrous instead of pubescent, and the leaves
are broadly lanceolate and apiculate.

14. ANULOCAULIS Standley.

Anulocaulis Standley, gen. nov.

Boerhaavia of various authors, in part, not L.

Perennial herbs, stout and erect; stems glabrous, but the middle of each
internode usually provided with a reddish ring which exudes a mucilaginous
fluid; leaves with very thick, rigid, rather fleshy blades, opposite, margins fre-
quently lacerate, petioled; flowers in small clusters, these variously arranged,
sessile or pediceled, sometimes subumbellate, the clusters subtended by a few
small bracts; perianth funnelform with a prominent tube; fruit turbinate or
biturbinate, rather obscurely 10-ribbed.

There is no good reason why plants which differ so markedly as these from
typical Boerhaavias should be included in the genus Boerhaavia. Such treat-
ment is certainly not conducive to generic unity. The plants included in the
new genus may be separated at once by their distinct general appearance, due
especially to their large, thick leaves, the shape of the perianth which has a

distinct tube instead of being campanulate, and the 10-ribbed fruit of different
shape.

Doctor Heimerl® placed Boerhaavia leiosolena and B. eriosolena in a sep-
arate section of the genus, which he named Solenanthae. He remarks that
these two plants differ very much from the other species of the genus, but he
did not see fit to separate them more definitely.

15. BOERHAAVIA L.

-—«

Boerhaavia L. Sp. Pl. 38. 1753.

Annual or perennial herbs, slender, glabrous or pubescent, often with
glandular rings about the internodes; leaves opposite, the blades unequal, entire,
petioled or sessile; flowers small, variously arranged, each usually subtended by
1 or 2 minute bracts, on jointed pedicels; perianth campanulate, 5-lobed ; stamens
1 to 5, exserted or included, with very slender filaments which are united at
the base; fruit club-shaped to obpyramidal, 3 to 5-ribbed, 3 to 5-angled, or
sometimes with 3 to 5 low, thick, not membranous wings,

Type species, Boerhaavia erecta L.

The genus has probably a wider distribution than any other of the genera of
the Allioniaceae. It includes about fifty species besides those mentioned here.
They occur through the southern part of the United States, through Mexico, the
West Indies, a large part of South America, and the islands of the Pacific, in-
cluding Australia, and through southern and eastern Asia, Africa, and Spain.

The individual species differ from those of Abronia in that they often extend
over relatively large areas; wide distribution seems to be characteristic of a
majority of the species. B. erecta is a good example of such distribution.

Doctor Heimer] divided the genus (as it is defined here) into two sections,
the first, Pterocarpon, containing B. pterocarpa (several other related species
such as B, alata and B. megaptera should be included here); and the second,
Micranthae, including the rest of the species. The two sections are hardly
worthy of being maintained. The wings of the former section differ from the
ridges of the second merely in degree and it would be difficult to tell to which
some of the species should be referred. The genus as it is defined here is com-
posed of closely related species and is the most satisfactory of the large genera
of the family in this respect. '

A sheet of Palmer’s in the herbarium of the University of California and
one in the National Herbarium bearing this number contain a very different
plant described elsewhere as a new species.

3. Boerhaavia megaptera Standley, sp. nov.

Annual; erect, about 30 cm. high; branched from neur the base; stems
slender, sparingly short-puberulent; leaf blades 20 to 25 mm. long and 8 to
12 mm. wide, narrowly elliptical to almost linear above, of about the same
color on both surfaces, rather obtuse or mostly acute at the apex, obtuse at
the base; petioles about one-half as long as the blades: branches of the
inflorescence alternate, forming a narrow panicle; peduncles 1 cm. long or
more, each bearing an umbel of 8 to 5 pedicellate flowers; perianth about 1 mm.
long or slightly longer, pinkish; fruit 3.5 mm. long and about 2.5 mm. wide,
with 5 thin, broad wings, these only slightly narrowed toward the base and
above rounded slightly above the body of the fruit; body and wings glabrous
and smooth, not at all rugulose.

The only species with which this is likely to be confused is B. alata, from
which it may be distinguished by its fruit being acute below, while that of the
latter species is only slightly narrowed; by the fact, also, that the fruit is col-
lected in fascicles of 5 or 6 and is on shorter pedicels, and that the flowers of the
new species are much smaller. The fruit of the plant might almost place it
in Selinocarpus, but the wings, although large, are not membranous as in that
genus; the habit and flowers, too, show at once that it is a Boerhaavia rather
than a Selinocarpus, for which it has been mistaken. Type in the herbarium
of the University of Arizona, collected by Prof. J. J. Thornber on Flattop
Mountain, Tucson Mountains, altitude 850 meters, September 8, 1903, no. 162.

5. Boerhaavia maculata Standley, sp. nov.

Annual, erect; stems slender, much branched, minutely puberulent below or
mostly glabrous, brown-dotted, not glutinous above; blades lanceolate, about
25 mm. long and 5 mm. wide, acute, rounded at the base, brown-dotted on both
surfaces, paler below, mostly glabrous; petioles very short; inflorescence panicu-
late, much branched; flowers 2 or 3 mm. long, single or 2 or 3 in a fascicle, on

slender pedicels which are 6 mm. long or less; stamens included; fruit nar-
rowly obpyramidal in outline, almost 4 mm. high, truncate above, acute below,
with 5 comparatively thin, narrow, transversely wrinkled wings.

Type U. S. National Herbarium no. 22987, cotype in the herbarium of the
University of California; collected at Guaymas, Sonora, Mexico, 1887, Palmer
332, in part. The type sheet of B. alata S. Wats. also bears the same number,
but the plant is different, its fruit having thick,-corrugated wings, while that
of B. alata has much wider, thin, and rather membranous wings, which are but
little narrowed below. From B. triquetra this species is distinguished by its
larger fruit, its wider and more numerous wings, and the much narrower
spaces between the wings.

On the sheet in the National Herbarium which contains the type is a packet
containing fruit which seems not to belong to this plant, and which is probably
the fruit of an undescribed species, for it does not seem to agree with that of
any plant reported from Guaymas.

6. Boerhaavia universitatis Standley, sp. nov.

Annual erect, branched from near the base; stems with a short, rather pul-
verulent pubescence on almost every part, slender, conspicuously brown-dotted ;
leaf blades lanceolate, 20 to 50 mm. long and 5 to 10 mm. wide, acute, rather
obtuse at the base, of about the same color on both surfaces, conspicuously
black-dotted below; petioles very short; branches of the inflorescence alternate,
paniculate, slender; ultimate peduncles 10 to 12 mm. long; flowers almost ses-
sile, in umbels of about 5, whitish, 1.5 mm. long; fruit 2.5 mm. long, very nar-
rowly obpyramidal, with 5 thin, winglike ridges which are truncate above, the
body of the fruit rugulose between the wings.

This is nearest B. intermedia, from which it differs in its black-dotted leaves
and stems, lanceolate leaves, and more distinctly winged fruit. From B, erecta
it is distinguished by its narrower leaves, by the arrangement of the flowers in
umbels, all of the pedicels being attached at the very end of the peduncle
instead of at various points near its end, and by its more distinctly winged
fruit. Type in the herbarium of the University of Arizona, collected by
Thornber, September 2, 1903, on the campus of the university, Tucson, Arizona;
altitude 740 meters.

7. Boerhaavia erecta L. Sp. Pl. 3. 1753.

Type locality, “In Vera Cruce.”’

An erect annual; stems usually reddish below, simple at the base but branched
above, glabrous, or roughened below; leaf blades oblong-ovate, mostly obtuse
or acutish, 50 or 40 mm. long and 25 mm. wide, rounded or broadly cuneate at
the base, glabrous, paler beneath, black-dotted on the lower surface, the upper
blades narrower and more acute; inflorescence dichotomously paniculate-
branched; flowers about 1 mm. long, the perianth sparingly hispid; stamens
exserted; fruit in clusters of 8 to 6 at the ends of the slender peduncles, the
pedicels not attached at the very end of the peduncle, but at various points near
the end, each fruit on a pedicel as long as itself or shorter; fruit 3 or 4 mm.
long, narrow, truncate above, narrowly obpyramidal, with 5 ridges which are
low but distinct, the spaces between them more or Jess rugulose; fruit usually
green,

This is scarcely separable from B. erecta, as a species at least. The plant
is erect and rather more slender than the species, and its leaves are without
black dots benenth. Aside from these minor differences there seems to be little
variation from typical B. erecta,

Perennial, ascending; stems slender, minutely and sparsely puberulent
throughout, slightly glandular above, the stem appearing glabrous to the naked
eye; internodes long, 8 to 12 cm. ; leaf blades broadly ovate, obtuse at the apex
and conspicuously apiculate, broadly rounded at the base; petioles about one-
half as long as the blades; branches of the inflorescence very slender, forming
a narrow, mostly alternately branched panicle; fruit like that of the species.

Boerhaavia ramulosa Jones, Contr. Western Bot. 10: 40. 1902.

This differs from B. viscosa in the following particulars: The stems are not
glandular below but have a_ short, seattered, appressed, almost pulverulent
pubescence; the petioles and the branches of the inflorescence, especially the
pedicels, have a short, close, glandular pubescence. The variety is founded
on two sheets, one collected in the Organ Mountains, New Mexico, 1897, Wooton
421; the other collected on Perico Island, Florida, 1900, Tracy 6654. The two
plants, although widely separated geographically, appear to be the same in
all essential characters.

These Arizona collections are of rather doubtful determination; they seem
to have the small flowers, included stamens, and slender spikes of B. watsoni,
yet their localities should place them rather with B. coulteri:

19. Boerhaavia organensis Standley, sp. nov.

Annual ?, low, 20 to 25 em. high, branched from the base; stems minutely
puberulent below, glutinous above; blades 2 cm. long or less, elliptical to
lanceolate, thick, glabrous, paler below, rather obtuse at both ends, the petioles
short and thick; inflorescence diffusely paniculate, the branches rather stouter
than in B. gracillima; flowers solitary on filiform pedicels which vary in length
from 1 em. to shorter than the flower; no very good flowers on the type but
those present about 1 mm. long, each subtended by a short, lanceolate bract;
fruit glabrous, 3 mm. long and about 2 mm. wide, the ribs rather acute, much
wider above than below, almost truncate above, the ribs rugulose.

This is nearest B. gracillima, from which it differs in the smaller size of
the plant, less diffuse panicles, much smaller flowers, and the glabrous fruit
of different form. Type in the herbarium of the New Mexico Agricultural
College, collected in Filmore Canyon, Organ Mountains, New Mexico, October
23, 1904, Wooton. B. gracillima is common in the same locality.

tioned in the original description of that variety.

distinguishing this from the preceding species; there does not seem to be any
remarkable difference in size judging from type material of both species.

STANDLEY—ALLIONIACEAR OF THE UNITED STATES. 387

23a. Boerhaavia linearifolia glandulosa Standley, subsp. nov.

Perennial from a woody root; stems prostrate, branched, spreading, glandu-
lar-pubescent below, glandular above; leaves lanceolate, thin, green on both
surfaces, black-dotted below, short-petioled; flowers larger than those of B.
lincarifolia or B, tenuifolia, stamens 3.

Type in the herbarium of the Missouri Botanical Garden, collected in Texas
by Lindheimer in 1846, no. 510, as well as several other numbers of various
years’ collections. Also collected in southwestern Texas by Reverchon (no.
126). This is the only form belonging to this group that I have seen with
glandular hairs on the lower part of the stem; the plant, too, is larger and
more robust than the species; it may be specifically distinct.

The writer has seen representatives of all of the North American species
of Boerhaavia except the following:

BoERHAAVIA PALMERI 8S. Wats. Proc. Am, Acad. 24: 69. 1889.

Selinocarpus A, Gray, Am. Journ, Sci. II. 15: 262. 1853.

Perennial herbs or sometimes somewhat shrubby plants, ascending, erect,
or prostrate; leaves opposite, often unequal, sessile or petioled, entire, thick
and sometimes fleshy; flowers solitary in the axils of the leaves or clustered
at the ends of the branches; bracts when present, small and inconspicuous;
calyx funnelform, with a short and thick or long and slender tube which ex-
pands into a spreading limb; stamens 2 to 5, exserted; fruit with 3 to 5 prom-
inent, membranous wings.

2. Selinocarpus palmeri Hemsl. Biol. Centr. Am. 3:6, 1882,

The leaves of this plant are much like those of S, angustifolius, but are
covered with a close, appressed, whitish pubescence; young branches glabrous;
flowers funnelform, the perianth about 15 mm. long and 11 mm. wide, gradu-
ally widening from the base upward; stamens much exserted: leaves on the
young branches linear, thick, 25 mm. long.

lection; 5 miles east of Estelline, 1904, Reverchon 283; Estelline,

New Mexico: Delaware Creek, 1893, Nealley 10; south of Carrizozo, 1904,
Wooton 2821; Acoma, 1884, Lemmon,
The flowers of this species are often cleistogamous, but on specimens of the
species proper fully developed flowers can almost always be found.

4a. Selinocarpus diffusus nevadensis Standley, subsp. nov,

Leaves ovate, 15 to 18 mm. long and about 13 mm. wide, broadly obtuse,
often mucronate, rounded or truncate at the base, their margins entire and
smooth, the blades thickish, puberulent or often glabrous above: flowers all
cleistogamous,

This form differs from the species in its broader and more obtuse leaves
with entire margins; the leaves are also a bright yellowish-green in color; the
flowers seem to be always precociously fertilized. ‘The plant is readily dis-
tinguished by its general appearance and is probably a good species, but the
differences are difficult of definition.

THOMPSONELLA, A NEW GENUS OF CRASSULACEAE
FROM MEXICO.

By N. L. Brrrron and J. N. Rose.

In 1905 E'cheveria minutifora first bloomed in cultivation. It
flowered in the Missouri Botanical Garden, the New York Botanical
Garden, and one of the greenhouses of the Department of Agriculture
in Washington at the same time. It was studied independently by
the writers and Mr. C. Hf. Thompson, and all reached the conclusion
that it represented a distinct generic type. Material has repeatedly
flowered since that time, and now we feel justified in proposing this
new genus, named in honor of Charles Henry Thompson of the
Missouri Botanical Garden.

In 1907 Mr. C. G. Pringle collected a second species, which flowered
in the spring of 1908. This is described below.

Mr. Thompson has had under observation for several years two very
distinct species, one of which is probably 7. ménutifora and the
other an undescribed species. It seems best not to describe this
species at present, but to wait until further field work has been done.
Several years ago a plant bloomed in Washington which seemed to
suggest a fourth species, but as there is some doubt as to place of
collection it seems best to delay the publication of this also. The
genus with two species is described as follows:

Thompsonella Britton & Rose.

Acaulescent; basal leaves few, spreading, thick, oblong; inflorescence a loose
simple spike or in large specimens more or less compound: sepals 5, turgid,
erect, clavate: corolla somewhat angled in the bud, rotate, the tube proper very
short, the lobes lanceolate, spreading horizontally or somewhat detlexed between
the sepals: stamens 10, erect, about as long as the petals; carpels erect, con-
stricted at base; styles slender; scales minute.

Type species Echeveria minutifiora Rose.

The inflorescence is very unlike any other in this family which we have yet
studied. The flowers are arranged in spirals of three and are not. strictly
axillary, but stand, though directly over, at some distance above the subtending
bract; they are very unlike those of all the true Echeverias in having a strictly
rotate corolla and thinner petals.

REDISCOVERY OF ECHEVERIA CARNICOLOR.

By J. N. Rose.

When Britton and Rose published their revision of the Crassu-
laceae* they recognized 58 species of Echeveria. Most of these they
described from living material. It is probable that no one had ever
before had so full a representation of this genus, since only 4 known
species were wanting from their collections, viz, /. canaliculata
Hook., 2. carnicolor Baker, 2’. bifida Lindl, and F. teretifolia DC.
It isa great gratification now to be able to announce the rediscovery
of one of these. .

In October, 1906, Dr. C. A. Purpus, the well-known Mexican col-
lector, sent to the National Museum an Echeveria from the Barranca
de Tenampa, in the State of Vera Cruz. The three specimens sent
were at once planted, but did not flower until January, 1908, when
they were found to be #. carnicolor. This species has heretofore
been known only from the specimens in the conservatory of the late
W. W. Saunders, upon the basis of which it was described and figured
by Dr. J. G. Baker, in 1870, in Saunders’s Refugium Botanicum.?
As stated by Doctor Baker, this species is nearest 2’. Jurida, but it is
a much smaller plant with weaker flower stems and fewer flowers.
The leaves have a decided bluish tinge with hints of pink, and, espe-
cially when young, have a decided metallic sparkle, perhaps caused
by the papilla-like plates which cover their surfaces. The flowers
are sometimes more numerous than in the plant figured by Doctor
Baker, and the inflorescence is often compound. The plant is
easily propagated, since the small leaves of the flowering stems
readily fall off, soon rooting and forming new plants. In some
respects it is a more attractive plant than “’cheveria lurida, and it
may prove a useful plant for formal bedding.

The accompanying illustration will give a good idea of the habit
of a plant in flower. A description of this species follows:

Echeveria carnicolor Baker. PLATE XLVI.
Leaves 20 or more, forming a dense rosette, thickish but flattened, oblance-
olate-spatulate, 3 to 4 cm. long, acute, with a bluish metallic luster; flowering
stems 2 or 3, at first spreading, the upper part ascending or erect, very leafy
below; flowers 6 to 15; sepals ovate to lanceolate, spreading; corolla orange-
red, 12 mm. long.

THREE NEW SPECIES OF CRASSULACEAE FROM
GUATEMALA.

By J. N. Roser.

In 1906 Mr. Wilham R. Maxon was sent to Guatemala by the
United States Department of Agriculture. At my request he col-
lected and sent to Washington living and herbarium specimens of all
the Crassulaceae he could find. Three of these proved to be unde-
scribed. They have all flowered here in Washington, and small
plants are available for distribution. One of the illustrations here
used was made from a photograph taken in Guatemala, while the
other was taken from a potted plant in Washington.

Echeveria guatemalensis Rose, sp. nov. PLATE XLVII.

Stems branching especially at base, resembling somewhat both in habit and
foliage Sedum prealtum, 10 to 15 em. high; leaves equally distributed on the
stem, alternate, spreading nearly at right angles to the stem, fleshy but flattened
and thinner than in most species of this genus, 2 to 4 em. long, 2 em. or Jess
broad, spatulate, with a flat surface above, rounded at apex but with » decided
mucro, rounded below into a broad petiole, pale green, slightly glaucous, the
margius sometimes tinged reddish; flowering branch 20 to 30 em. long, from the
axil of a leaf near the middle of the stem, reddish, bearing numerous reddish
leaves: inflorescence an equilateral raceme bearing 20 or more flowers : pedicels
3 to 4 mm. long; sepals linear, acute, spreading nearly at right angles to the
pedicels; corolla buds broadly ovoid, acute, the corolla when open 10 mm, long
and broad in) proportion, pinkish below, yellowish above, the lobes acute;
stamens 10, shorter than the corolla.

Collected by Mr. William R. Maxon, on Volean de Agua, at an altitude of
2,700 to 8,000 meters, Guatemala, March 22, 1905 (no, 3726) and flowered in
Washington, May, 1907,

Echeveria maxonii Rose, sp. nov. PLATE XLVITI,

Stems glabrous, frutescent, at first erect, becoming decumbent, 60 to SO em.
long, naked below, very leafy near tips; leaves on young or slowly growing
plants massed near the top but in vigorous shoots rather distant, standing at
right angles to the stem, 3 to 10 em. long, spatulate, narrowed at base into a
more or less definite petiole, rounded below, decidedly trowel-shaped above,

obtuse or acutish, green on the under surface, not at all glaucous, the margins
more or less purplish; inflorescence an equilateral raceme or sometimes becom-
ing a narrow panicle; peduncle elongated, 20 to 30 cm. long, leafy (in our
herbarium specimens often naked); sepals distinct, semiterete, acute, glaucous,
unequal, spreading with age; petals distinct nearly to the base, erect except the
tips, these spreading, salmon-pink in color; stamens 10; scales white.

Collected by William R, Maxon, at Chuacts, between Salama and Las Canoas,
January 22, 1905 (no, 3406, tvpe), and at Zunil, Department of Quezaltenango,
Guatemala, February 24, 1905 (no. 3605). Ample living material of the first
number was sent to Washington and has been used in drawing up this descrip-
tion. These plants grew in the pockets of nearly solid rocky slopes, falling
down over the surface, as shown in the accompanying illustration. Here they

REDISCOVERY OF CEREUS NUDIFLORUS.
By J. N. Rose.

About 1854 Charles Wright collected in Cuba a tree cactus which
Dr. George Engelmann described in 1869 as Cereus nudiflorus. Since
its publication, so far as I can learn, this species has not until re-
cently been re-collected, and has received very little further notice.
Engelmann himself published nothing additional upon it, and the
name fails to appear at all in the index to his “ Botanical Works.”
The name is also entirely overlooked by the “ Kew Index.” Schu-
mann, in his * Monograph of the Cactaceae,” merely refers the species
to Cereus lepidotus. Material lately collected, however, places the
species in full light and vindicates its claims to independent standing.
In the spring of 1907 Mr. William R. Maxon was detailed by the U.S.
National Museum to carry on botanical explorations in eastern Cuba,
with verbal instructions to pay especial attention to the Cactaceae.
This work was carried on with much enthusiasm and thoroughness,
and one of the results was the collection of a fine series of speci-
mens of Cereus nudiforus. A number of cuttings were sent to Wash-
ington, but these unfortunately rotted during shipment.

Flowers were preserved in alcohol, however, good herbarium speci-
mens were obtained, and arrangements were made for obtaining
additional material and photographs. Soon after Mr. Maxon’s return
Mr. Theodore’ Brooks, of Guantanamo, sent him a photograph of an
old tree taken in the winter of 1888-1889 near Novaliches not far from
Cafos. Unfortunately this photograph is too much faded to admit
of reproduction. It is of interest as showing not only the tree, which
is a very large one, but the figure of Baron Eggers standing near it.
The species is thus shown to have been known to Baron Eggers, but
whether or not he actually collected specimens I do not know. Again
in August, 1906, Mr. Brooks sent two negatives and two prints of a
tree 8 meters high, in fruit, found at Los Canos. One of the prints
is here reproduced. He also sent, in sections, two mature fruits, one
of which has been reconstructed and photographed for reproduction
here. This seems to be the first time the fruit has ever been preserved

Besides Mr. Brooks’s contributions Mr. Maxon received from Mr.
Jennings 5. Cox, of Santiago de Cuba, in July, 1907, 4 photographs
representing different views of a tree of this species, one of which is
here reproduced.

FRUITING BRANCHES OF PERESKIA AUTUMNALIS (EICHLAM) ROSE.

A SPECIES OF PERESKIA FROM GUATEMALA.

By J. N. Rosr.

Since 1902 I have had knowledge of a most remarkable species of
Pereskia in Guatemala. My attention was first called to it by Dr.
QO. F. Cook, who collected specimens and, with Mr. G. N. Collins,
obtained several excellent photographs. Soon after that time, and

again in 1906, as also in 1907, Prof. W. A. Kellerman obtained photo-

graphs and some excellent specimens. This last material, received

coon after the death of Professor Kellerman, has led me to re-examine
all the material at hand and to describe it as new. It has been sug-
gested that there may be more than one species in Guatemala, but
while my material shows considerable variation this is not such that
I feel warranted in dividing it. This Guatemalan species has some-
times been called P. nicoyana, but it differs from that species in habit,
the petals are not fringed, and the axils of the leaves are not hairy.

Pereskia autumnalis (KEichlam) Rose. Puates LII, LIII, LIV.

Pereskiopsis autumnalis Eichlam, Monatsch. Kakteenk, 19: 22, 1909.

Tree 6 to 9 meters high, with a large, rounded, much branched top, the trunk
usually very definite and 40 cm, or more in diameter; young branches cherry-
brown, smooth: axillary spines usually very slender, generally single, some-
times in threes, 3 to 4 cm., rarely 8 cm. long; leaves thickish, oblong to orbicu-
lar, 4 to 8 em. long by 3 to + cm. broad, round or somewhat narrowed at base,
mucronate-tipped ; flowers sessile or nearly so; ovary bearing ovate leafy bracts ;
sepals ovate, acute, naked in the axils; petals entire, perhaps about 1 cm. long,
red: fruit globular, 4 to 5 cm. in diameter, fleshy, glabrous, bearing scattered
leafy bracts, these naked in the axils: seeds black, glossy, 4 mm. long.

The following herbarium material has been examined :

From El Rancho, W. A. Kellerman, December 28, 1908, nos. 7011 and 7014;
also from the same locality, O. F. Cook, April 9, 1902.

In addition to this I have examined various bottled specimens and a fine
series of 9 photographs, a part of which are here reproduced.

aAfter this paper had gone to the printer I learned from Mr. Eichlam, of
Juatemala City, that he was about to publish a new species of Pereskiopsis.
His paper is now at hand and contains a very full and interesting account of
his species. A careful reading of the description of Pereskiopsis autumnalis
convinees me that his species is the same as the one I had proposed to publish
here as new. I have therefore substituted his specific name in place of the one
I had in proof. I can not agree with him, however, that it belongs to Pereski-
opsis. The fruit and seeds are very different from those of that genus. The
seeds of this species, as described above, accord with Pereskia while those of
true Pereskiopsis approach those of Opuntia.

NEW SPECIES OF OPUNTIA FROM ARIZONA,

By J. N. Roser.

During a part of April and May of 1908 TI was located at Tucson,
Arizona, the guest of the director of the Desert Laboratory of the
Carnegie Institution. While there I frequently visited Tumamoce
Hill, upon which the laboratory is built. Upon this hill was found a
profusion of the prickly pears or flat-jointed Opuntias. A careful
examination of these plants led me to believe that there were among
them at least four well-defined species. Further study in the Cata-
lina Mountains, Tucson Mountains, Tortolitas Mountains about
Tucson, and the Whetstone Mountains about Benson, convinced me
that these were not mere mutations but well-established species ex-
tending over large areas of southeastern Arizona. After reaching
the conclusion that there were four species on Tumamoe Hill, I went
over the material with Dr. D. T. MacDougal, Prof. J. J. Thornber,
and Mr. J. C. Blumer, all of whom agreed with me in my conclusion,
Since returning to Washington I find that Prof. J. W. Toumey has
collected three of the species, considering them distinct. One of these
he has called O. lindheimeri, but this was at a time when 0. Jind-
heimeri was supposed to be a very polymorphic species and to extend
from eastern Texas to the Pacific Ocean. O. “indheimeri is now
known tobe a pretty uniform species with a much more limited range.
O. engelmanni, which has also passed as O. lindheimeri, has been
rediscovered at the type locality and found to be, not only very
different from O. lindheimer?, but very unlike any of our Arizona
species. Another of the three Professor Toumey called O. phaea-
cantha, but an examination of the type sheet of that species, now in
the Missouri Botanical Garden herbarium, shows that this reference
also is a misidentification, and I have named the plant O. blakeana.

It was my original expectation to publish all four of these species
as new, but long after this paper had been prepared and just as it
was going to press I discovered that one of the species had been
described by Dr. David Griffiths as O. discata.

FLOWER OF ECHINOCE REUS BAILEY! ROSE,

ECHINOCEREUS BATLEYT, A NEW CACTUS FROM
OKLAHOMA,

By J. N. Roser.

In 1904, James H. Gaut while collecting in the Wichita Mountains
for the Biological Survey of the Department of Agriculture sent me
two specimens of an Echinocereus. which at first T supposed to be a
peculiar form of Echinocercus cuespitosus. Further examination of
these plants showed very marked difference in the habit and in the
arrangement of spines. Both these plants died without flowering.
In 1906 Mr, Vernon Bailey also obtained from the Wichita Moun-
tains several specimens, one of which flowered in 1907,

The species may be described as follows:

Echinocereus baileyi Rose, sp. nov. Puates LVI, LVIT.

Plant body cylindrical, 10 cm. or so high; ribs 15, straight or perhaps some-
times spiral; areoles elongated, separated from the adjacent ones by a space
of about their own -length; spines at first white, when mature brownish or
yellowish, about 16, somewhat spreading, those at the top and base of the
areole smaller; central spines none; areoles when young clothed with dense
white wool, this nearly or quite wanting in age; flowers from the youngest
growth appearing terminal; corolla widely spreading, 6 cm. or more broad:
petals light purple, oblong to spatulate-oblong, the broad apex toothed or
jagged, the terminal tooth tapering into a slender awn: filaments short, yellow:
style stout, longer than the filaments: stigmas 10, obtuse, green; areoles of the
ovary bearing 10 or 12 slender spines intermixed with cohbwebby wool, the spines
whitish, or the central ones brownish ; areoles of the tube crowning an elongated
tubercle, not so closely set, bearing spines subtended by minute leaves.

In October, 1907, IT described * Vopalea quatemalensis, which was
then supposed to be the only endemic species of the genus in Guate-
mala. In December of the same year Prof. W. A. Kellerman wrote
me from El] Rancho that he had discovered there a second species.
Abundance of material was collected, which, after the lamentable
death of Professor Kellerman, was sent to Washington by his assist-
ants, Mr. H. E. Barber and Mr. J. F. Zimmer.

Nopalea lutea Rose, sp. nov. PLATE LVIIT.

Probably arborescent, joints obovate to spatulate, 1 to 1.5 cm. Jong; areoles
about 2 cm. apart, large, made up of a prominent cushion of short hairs filled
with numerous yellow spines and bristles; spines weak, usually about 2 em.
long; flower 5 cm. long; petals red, 2 cm. long; ovary covered with prominent
areoles filled with weak yellow spines and bristles.

Collected by Prof. W. A. Kellerman and assistants, near El Rancho, Guate-
mala, altitude 800 meters, December 28, 1907 (no. 7046).

This species is very unlike the other known Nopaleas in having weak spines.
Professor Kellerman says it differs from N. guatemalensis in having a honey-
yellow green color instead of gray green. The flowers are smaller and of a
lighter red color.

CONZATTIA A NEW GENUS OF CAESALPINTACEAE.

By J. N. Rose.

ry

While collecting on the dry limestone hills west of Tehuacan, Mex-
ico, in 1905, with Mr. Jos. H. Painter, I found a very curious legu-
minous tree which much resembles an Acacia in habit and foliage.
It was long past flowering time and most of the pods were deformed
or abortive, due to the sting of some insect, but a few unripe ones
were found to which a stamen or two still clung, showing the rela-
tionship to be not with Acacia but with the Caesalpiniaceae. This
material was brought to Washington and carefully examined, but
could not be identified. In 1906, a little later in the season, I again
visited Tehuacan and succeeded in gathering mature seeds, but still
no flowers. Later in the same year Prof. C. Conzatti sent me speci-
mens with immature pods, which he had obtained in June, and, finally,
in 1907. he sent me flowers collected by him on May 12 of that year.
Upon this material, together with a photograph showing the habit
and also a seedling now growing in Washington, I am able to present
a full diagnosis of this tree. It proves to be a very distinct genns,
perhaps nearest Cercidium, but never thorny, and differing from it
decidedly in other respects, especially in foliage and fruit. It gives
me great pleasure to name it for my good friend, Prof. C. Conzatti,
director de la Escuela Normal in the city of Oaxaca, Mexico, author
of “Los Generos Vegetales Mexicanos,” and a most painstaking
botanical collector. He has on several occasions assisted me in my
field work, as he has also many other naturalists, and has contributed
many valuable specimens to the National Herbarium.

Conzattia Rose, gen. nov.

Calyx tube campanulate, very short. much shorter than the lobes; lobes
valvate, becoming reflexed, subequal; petals 5, yellow, equal, distinct; stamens
10, erect: filaments glabrous except at the base, here hairy; ovary (in all
specimens seen apparently abortive) white-woolly;: legume strongly flattened,
few-seeded, dehiscent, the seeds oblong, albuminous; cotyledons oblong, entire.
Tree or large shrub, usually with a very distinct trunk and a broadly spreading
top. Leaves large, twice-pinnate (seedling leaves onece-pinnate) with many
pinne and leaflets, Stipules minute. Flowers yellow, in slender racemes.

CONZATTIA ARBOREA ROSE.

TWO NEW SPECIES OF ACACIA OF THE SERIES
FILICIN AE.

By J. N. Roser.

When Bentham published his great work on the “ Mimosaeae,”
in 1874, he reduced some 23 species of Acacia belonging to the series
Filicinae to the two species Acacia villosa and A. filicina. Since then
no one has published on the group and Bentham’s conclusions have
been generally accepted. Doctor Small, in his “ Flora of the South-
eastern United States,” has restored one of these names, viz, A.
cuspidata, and Dr. William Trelease has supplanted filécina by the
older filicioides.. A study of the material from Mexico and our border
States convinces me that the group is sadly in need of revision.
Recently I examined material grown near Tucson, where there seem
to be two distinct species. One of them may be the Texan species
A. texana, but the other is certainly undescribed. In the herbarium
was found a third species from the Huachuca Mountains, likewise un-
described. These two species may be characterized as follows:

Acacia lemmoni Rose, sp. nov.

Branches stout, pilose; pinnze 5 to S pairs; leaflets 9 to 20 pairs, green,
oblong, acute, 6 to 8 mm. long, both middle and lateral nerves prominent ;
sepals and petals glabrous; pods pubescent, 4 to 6 cm. long, 8 mm. broad.

Collected by J. G. Lemmon on Huachuca Mountains, September, 1882,

Type U. S. National Herbarium no. 41089,

This species is stouter than the next and with larger acute and prominently
veined leaflets.

Acacia suffrutescens Rose, sp. nov.

Stems low, 10 to 30 cm. high, shrubby at base, the top killing back each year;
branches, rachis of leaves, and peduncle pilose; pinnz usually 8 to 12 pairs;
leaflets numerous, linear-oblong, 4 to 5 mm. long, acutish, glabrous, the veins
indistinct except the central one; sepals and petals glabrous; fruit glabrous,
4 to 5 em. long, 6 to 7 mm. broad.

Common in the valley and mountains near Tucson.

The Chinese fern here described as new was detected several years
ago in the course of a study of Asplenium trichomanes and its allies.
Its relationship is discussed below.

Asplenium microtum Maxon, sp. nov. PLATE LX.

Rhizome suberect, 5 to 7 mm. in diameter, thickly beset with rigid linear-
lanceolate dark brownish scales about 2 mm. in length; fronds few (4 to 8),
cespitose, divergent, subarcuate, 15 to 20 cm. long; stipes dull purplish black,

flexuose, 2 to 3 em. long; lamina 12 to 17 em. long, 11 to 13.5 mm. broad,

linear: pinnze subcoriaceous, deciduous, 25 to 32-jugate, mostly opposite or sub-
opposite, approximate or their width apart, gradually reduced both above and
below; characteristic middle pinnre 6 to 7 mm. long, sessile, subrhombic to
oblong, the base appearing (in dried specimens) narrowly long-cuneate, some-
what excised below, auriculate above, the apex rounded, the margins lightly
crenate-sinuate, revolute in drying; lower pinnze shorter, broader, decidedly
auriculate, somewhat refiexed, easily deciduous, the lowermost 2 or 3 distant,
greatly reduced, subalternate or alternate, a minute, persistent bud with con-
spicuous chaff borne commonly at the base of the last or next to the last;
stipe and rachis narrowly alate, the wing conspicuously erose-dentate or even
serrate; sori medial, linear-oblong, usually 6 (in 3 pairs) or 7, the odd one
in the upper row; indusia ample, firm, glabrous, the margin lightly sinuate ;
spores dark brown, ovoid, somewhat cristate, conspicuously alate and reticulate.

Type in the U. S. National Herbarium, no. 455004; from Mengtse, Yunnan,
China, A. Henry (no. 10344). The same number in the herbarium of the
Missouri Botanical Garden bears the additional data: “s, w. mts., alt. 6000 ft.”

Mentioned by Christ,* some time ago, under the name Asplenium trichomanes,
as a form ‘“ with distant strongly auriculate pinne.” A. microtum is, appar-
ently, a near relative of A. trichomanes; but from this, which, in a typical
state at least, seems to be confined to North America and Europe, it differs
very noticeably in (1) its subcoriaceous texture, (2) its auriculate pinne, these
narrowly cuneate at the base (really less so than appears in the dried plants),
(3) its strongly revolute and lightly crenate-sinuate murgins, and (4) the
presence of a minute but very chaffy bud upon the rachis, near its base.
This last is a character noted hitherto, in the group of Asplenium trichomanes,
only in A. platyneuron and A. monanthes; in the former very rarely; in the
latter commonly, sometimes near the base, but often in the apical portion.
A Mexican species of this group, as yet undescribed, has the fronds radicant
and proliferous at the very apex.

For the drawing herewith reproduced the writer is indebted to Dr. H. D.
House, of the Biltmore Forest School.

PREFACE.

The present issue of the Contributions is made up of miscellaneous
papers. The first three are continuations of studies published earlier
in this series respectively on the Cactaceae, Crassulaceae, and Apiaceae,
families which have presented unusual difficulties to botanists, and to
which Dr. J. N. Rose, Associate Curator of the National Herbarium,
has devoted special study in collaboration with Dr. N. L. Britton, of
the New York Botanical Garden, and Prof. John M. Coulter, of the
University of Chicago. The last paper, by G. N. Collins, Assistant
Botanist in the Department of Agriculture, is an account of a remark-
able development in a maize plant grown in a temperate climate from
seed produced in the tropics. It is a suggestive illustration of the
effect of environmental change.

These papers form the concluding part of Volume XII of the
Contributions. The title-page and index of the volume will be issued
later.

THE GENUS CEREUS AND ITS ALLIES IN NORTH AMERICA,

By N. L. Brirron and J. N. Roser.

INTRODUCTION.

Studies of North American Cactaceae, conducted now for several
years in the museums and greenhouses at New York and Washington
and supplemented by field work in the West Indies, Mexico, and the
southwestern United States, have rendered us familiar with the habit
and morphology of a large number of species. The information thus
obtained makes it clear that a considerable number of generic types
must be recognized, additional to those established by previous
authors, in order to present a rational classification of this family.
We have been greatly aided in our study by A. Berger’s admirable

paper entitled, “‘A systematic revision of ‘the genus Cereus Mill.”*
This is by far the most satisfactory treatment of the group which has
everappeared. We think, however, that he has erred in referring to
Cereus the genera Cephalocereus and Echinocereus, which are now
almost universally considered distinct.

But it is also true that these units have no more claim to generic rank
than most of the other subgenera established by him. While, there-
fore, we differ from Mr. Berger as to the importance of these groups,
we realize that he has been consistent and logical in his work. The

genera have very distinct flower and fruit characters as well as clearly
defined habit and stem structure. We have experienced some difli-
culty in forming a lineal arrangement of the genera which seemed to
be logical. Mr. Berger’s arrangement as given in his synopsis of the
subgenera of Cereus is in the main satisfactory but has certain defects.
We have formed a new arrangement which will be followed here,
although further study will doubtless lead to various changes in it.
Although the present paper deals only with North American species,
we may express the conviction incidentally that Eulychnia of Philippi
and Cleistocactus of Lemaire, South American groups, should be re-
stored to generic rank.

In the present communication we submit a list, with bibliographic
references and indication of geographic distribution and of type local-
ities, of the genera and species with descriptions of the genera.

Plates LXV and LXVI and LXVIII to LX XIII are from photo-
graphs furnished by Dr. D. T. MacDougal, which are here used by
courteous permission of the Carnegie Institute of W ashington.

This species was described from cultivated specimens which were said to have
come from ‘‘Sonora.’’ So far as we know no species of this genus has in ‘recent
years been collected in, Sonora, but Dr. E. Palmer collected from some Cephalo-
cereus in a barranca near Batopilas, Chihuahua, in 1885, long hair similar to that
figured by Lemaire. This barranca runs down into Sonora. Schumann onty refers
to a plant collected at Naulingo, between Vera Cruz and Jalapa. This is undoubtedly
a different species.

examined) 7, 2 em. deep, marked by a pair of grooves descending obliquely, one on
each side, from the areoles; areoles closely set, usually 1.5 cm. apart; radial spincs
at first 7 or 8, others apparently developing later; central normally one; all spincs
short, 1 em. or less long, at first straw-colored, in age grayish; all areoles producing
few or many cobwebby hairs; the flowering areoles appearing on one side of the
plant, in the specimen under observation on a single rib, and producing long white
hairs 4 to 6 cm. long; flowers 6 to 8 cm. long, ‘dirty rose red;”’ fruit red.

Described from two young plants and the top of an old one sent by Dr. C. A. Par-
pus and the late Dr. A. Sartorius from the State of Veracruz, Mexico.

This giant cactus is common on the edge of the pedregal near Cuernavaca and
extends for many miles down the valley southward.

The species is near P. pecten-aboriginuim but is generally more branched and prob-
ably larger. Technically, it has very different areoles and much longer spines.

Lemaireocereus treleasei Rose, sp. nov. Puate LXX.

Plants 5 to 7 meters high, simple or with a few strict branches; ribs about 20;
areoles closely set, each with a peculiar V-shaped depression just above it; spines
rather short, yellowish; flowers pinkish, 4 to 5 cm. long, diurnal; bracts on ovary
and flower tube bearing slender whitish bristles; fruit red, about 5 cm. in diameter,
covered with clusters of deciduous spines; seeds black with a dull rugose surface and
a large oblique basal hilum.

Collected by J. N. Rose on the road between Mitla and Oaxaca, September 5,
1906 (no. 11300, type). The species had previously been collected by Dr. William
Trelease in this same region.

Type U.S. National Herbarium no. 454090.

This species has flowers and fruit much resembling those of Lemaireocereus stellatus,
but it has a different habit, the stems have more ribs, and it has different areoles.
Mr. C. H. Thompson, of the Missouri Botanical Garden, has called my attention to

anomalus Cereus. The two seem to form a well defined group and are therefore
brought together under the above generic name.

The genus is named for Brig. Gen. Timothy EK. Wileox, U. 8S. A., retired, who
has been an enthusiastic student of plants for many years.

ECHEVUERIA TRIANTHINA ROSE

FIVE NEW SPECIES OF CRASSULACEAE FROM MEXICO,
By J. N. Rose.

No other group of flowering plants make in general such unsatis-
factory herbarium specimens as do the Crassulaceae when treated in the
usual way. In some species the stem leaves drop off easily, and in
nearly all they will gradually detach themselves unless specially
treated. Some species will grow in the herbarium for months, taking
on abnormal shapes and gradually becoming dismembered. In nearly
every case it is best to prepare herbarium specimens by plunging the
entire plant or its parts into boiling water, in some cases allowing
the material to remain seyeral minutes. In this way the tissues
are killed and the plant dries readily. By this treatment, how-
ever, the shape of the leaves is destroyed, and in the case of the thick
terete leaves some very important characters are lost. Indeed, it
seems almost impossible to identify some of the older species even with
the type‘in hand. Owing to the great number of species recently
described from Mexico, and the indications that many more are to be
described, it seems highly desirable that the habit and foliage especially
should be shown either by photographs or by drawings. In my own
work I shall try in the future to photograph all new species which are
described from living material.

The present paper contains descriptions of some miscellaneous new
species, all of which are accompanied by full-page illustrations.
Echeveria bifurcata Rose, sp, noy. Piate LXXVIT.

Caulescent, usually forming a simple rosette of leaves; basal leaves lanceolate,
acuminate, rather bright green, apparently never coloring very much, 5 to 7 em.

SUPPLEMENT TO THE MONOGRAPH OF THE NORTH AMERICAN
UMBELLIFERAE, *

By Jonn M. Courter and J, N. Ross.

INTRODUCTION.

In 1888 we published the Revision of this family, and in 1900 our
Monograph appeared. Since the latter publication enough material
has accumulated to justify a short Supplement. Itis to be remem-
bered that the area covered is North America north of Mexico. This
Supplement includes a record of all new species described since 1900 .
and of all transfers made by others which have seemed to us justifi-
able; descriptions of two new genera and six new species; the entry
of a well-established introduced species; certain transfers which have
seemed to us necessary; and a bibliography for the period since 1900.
We have not included all changes that have been proposed, either
because our material does not warrant an opinion, or because they do
not seem to us to be justified. It is to be understood, therefore, that
we have made no changes in the names used in the Monograph except
as they are indicated in this Supplement.

BIBLIOGRAPHY.

The following citations include all publications of new species and
varieties, within our range, since the appearance of the Monograph;
and also the transfers from one genus to another in so far as they
seem to us to be justified :

two preceding ones. Under the Vienna rules, it is made an exception to the rule for

the formation of family names.

GENERA AND SPECIES.
HYDROCOTYLE L. Sp. Pl. 234. 1753.

Hydrocotyle rotundifolia Roxb. Hort. Beng. 21. 1814.

This species is native of Tropical Asia and Africa. It is grown in many places as
a carpet plant under the name of Sibthorpia europea and is now an escape in a few
places in this country. It was observed a number of years ago by J. N. Rose in
Washington, where it now appears every year in the grounds about the National
Museum; again in lawns in West Chester, Pennsylvania, by F. Wendle; and more
recently at Louisville, Kentucky, by H. Garman, who states that it is a pest ina
cemetery there. For further comment see Bailey’s Cyclopedia of American Horti-
culture.

ERYNGIUM L. Sp. Pl. 232. 1753.

Dr. J. K. Small has described the following species, which is closely
related to AL diffusum:
Eryngium compactum Small, Fi. Southeast, U. 8. 865, 1903.
SANICULA L. Sp. Pl. 235. 1753.

Sanicula serpentina I ]mer, Bot. Gaz, 41: 312. 1906,

Sanicula tripartita Suksdorft, Allg. Bot. Zeit. 12:5. 1906.
We have not seen this species, which comes from Washington.

CHAEROPHYLLUM L. Sp. Pl. 258. 1753.

Mr. B. F. Bush has prepared a most excellent monograph of this
genus, which was published in the Transactions of the Academy of
Science of St. Louis.

His key to the species is as follows:

BUPLEURUM lL. Sp. Pl. 236, 1753.

Bupleurum purpureum Blankinship, Mont. Agric. Coll. Sci. Studies 1: 89. pl. 3.
1905.

This species is said by Blankinship to differ from B. americanum in its low sub-
acaulescent habit, shorter leaves, wider obtuse involucel bractlets, smaller heads,
smaller dark purple flowers, and shorter mericarp with fewer oil tubes in the inter-
vals, and in its alpine habitat.

ZIZIA Koch, Nov. Act. Caes. Leop. Acad. 12: 128. 1824.

The following species of Zizia from Georgia has been described
since the publication of our Monograph:

CARUM L. Sp. Pl. 263. 1753.

Carum montanum Blankinship, Mont. Agric. Coll. Sci. Studies 1: 89. pl. 4. 1906.
According to Blankinship it differs from C. gairdneri in its larger size, larger leaves,
pinnately incised leaflets, large fruit, and longer styles.

Carum garrettii A. Nelson, sp. nov.

From a fascicle of fusiform roots, 60 to 100 cm. high; stem stouter than that of C.
gairdneri; leaves simply pinnate or the uppermost simple, on long petioles gradually
dilated into the broad base; leaflets from narrowly to broadly lanceolate or oblanceo-
late, or even ovate, 2 to 6 em. long, from sessile to long-petioled; bracts 1 or 2;
bractlets several, small, subulate; rays 6 to 12, 2 to 4.cm. long; raylets about 20, the
pedicels very slender, less than 1 cm, long; fruit ovate, about 2 mm. long; stylo-
podium low-conical; oil tubes very large, filling the whole interval, only two on the
narrow commissure; seed terete but for the depressions below each oil tube.

All the specimens were secured by Mr. A. O. Garrett, of the Salt Lake City High
School; no, 2053 (in fruit), Wasatch Mountains, Utah, September 6, 1906 (type) ;
no. 2158 (in flower), City Creek Canyon, Utah, July 25, 1907.. Mr. Garrett is grow-

Discopleura costata Chap. Fl. South. U.S. 162. 1860.

Stems stout and erect, 120 to 150 em. high, 1 em. in diameter, hollow, strongly
fluted; leaves long-petioled, somewhat rigid, finely dissected, the segments verv nu-
merous, crowded, and appearing verticillate; peduncles short and stout, 10 em. long
or less; involucral bracts simple or deeply cleft; involucel bractlets linear, entire,
short; umbels few, large; rays 4 cm, long; pedicels 7 mm. long; flowers autumnal,
white; fruit ovate, 4 to5 mm. long, the dorsal and intermediate ribs prominent;
style slender, much longer than the prominent stylopodia.

“Swamps along the margin of the Ogeechee River,’? Georgia (type locality), and
swamps near Wilmington, North Carolina.

When the Monograph was written, our only material of this form consisted of
flowering specimens from G. MeCarthy, collected in swamps near Wilmington,
North Carolina, and attention was called to the stouter habit and the leaf characters
in which it differed from P. capillaceum. Edwin B. Bartram has now sent us
fruiting material from Wilmington which confirms Elliott’s statement as to its
autumnal habit and larger fruit with more prominent ribs. Mr, Bartram’s letter is
as follows:

In your Monograph of the Umbelliferae I notice a reference to aspecies of Ptilim-
nium from Wilmington, North Carolina, that had not at that time been collected
in good fruiting condition. While collecting in this region last fall, 1 noted this
plant with particular interest and was fortunate in securing one head with mature
fruit. The plants I observed had finely dissected, rather rigid leaves, and stout hol-
low stems about 1 em. in diameter at the base and averaged about 12 dm. in height.
It seems to be very distinet from P. capillaceum of the coastal plain, and the long
recurved styles as well as the size and shape of the fruit and general habit rather
suggest some specific if not generic distinetion.

Ptilimnium missouriense ©. & R. sp. noy,

Stems stout, 60 to 90 cm. high, somewhat fluted; leaves short-petioled, finely dis-
sected; peduncles 16 em. long or less; involucral bracts simple or cleft, linear or with
linear lobes; involucel bractlets linear, entire; rays 10 to 35, nearly equal in each
umbel, 2 to5 cm, long; pedicels 3 to 8 mm. long; flowers autumnal, white; calyx teeth
acute, prominent but shorter than the stylopodium; fruit broadly ovate, 2 to 3 mm.
long; dorsal and intermediate ribs filiform; stylopodia prominent; styles long, slender,

Collected by George W. Lettermann at Allenton, Missouri, August 27, 1878 (type),
and by B. F. Bush in Butler County, Missouri, October 16, 1905 (no. 3709).

Type in U. 8. National Herbarium no, 140648.

This species has been distributed as P. nuttallii, but its very different fruit justifies
our giving it specific rank.

Ptilimnium texense C. «& R. sp. nov.

Stems slender, erect, 70 to 90 em. high, somewhat branching near the top; leaves
short-petioled, finely dissected, the segments numerous and filiform; peduncles slen-
der, 10 em. long or less; involucral bracts numerous, 3-parted, the lobes linear;
involucel bractlets linear, entire; rays about 20, nearly equal, 4 em. long; pedicels
6 to 8 mm. long; flowers autumnal, white; calyx teeth large; fruit oblong, 2 mm.
long; dorsal and intermediate ribs filiform; stylopodia prominent, crowned by the
short styles.

Collected by F. W. Thurow, near Hockley, Texas, September, 1890.

Type U.S. National Museum no. 41256.

A reexamination of this material has convinced us that this is a good species, com-
bining, as stated in the Monograph, the cleft involucral bracts, characteristic fruit
ribs, and shorter styles of P. capillacewm with the stouter habit, smaller fruit, and
larger calyx teeth of P. nuttalli’.

C. & R34
Ligusticum affine A. Nelson, Bull. Torr, Club 28: 225. 1901.
LIGUSTICELLA ©. & R. gen. nov.

Calyx teeth evident; fruit ovate, flattened laterally, glabrous; carpel with filiform
ribs, the laterals no more prominent than the dorsals; stylopodium conical; oil tubes
2 or 3in the intervals, 4 on the commissural side; seed considerably broader than
thick, with nearly plane face.

Low, glabrous, acaulescent perennials, with small, simply pinnate leaves, no
involucre (rarely 1 or 2 caducous bracts), involucels of broad, toothed bractlets, and
yellowish green flowers in few-rayed, compact umbels.

The genus is founded on Ligusticum eastwoodae C. & R., and differs from Ligusticum
in its acaulescent habit, simply pinnate leavex, smatl and compact few-rayed umbels,
yellowish flowers, and equal filiform ribs of the fruit. It resembles Orumbella in
habit and foliage; but that genus has a conspicuous involucre, prominently ribbed
fruit, and purple flowers. Furthermore, Orumbella is an Alaskan coast plant, while
Ligusticella is a high alpine plant of Colorado.

30-rayed, the involucre wanting or represented by 1 or 2 more or less conspicuous
bracts; involucels none; rays 5 to 8 cm. long, nearly or quite glabrous; fruit oblong-
elliptic, obscurely and sparsely hirsute, less than 5 mm. long; lateral wings broader
than the low dorsal and intermediate ones; oil tubes solitary in all the intervals;

PSEUDOTAENIDIA Mackenzie, Torreya 3: 158. 1903.

‘This genus has been described since the publication of the Mono-
graph, and is represented by the following species from the moun-
tains of Virginia and West Virginia:

Pseudotaenidia montana Mackenzie, loc, cit. 159.
LEPTOTAENIA Nutt. in Torr. & Gr, Fl], 1: 629, 1840,

Cusickia Jones, Contr. Western Bot. 12: 39. 1908.

In the generic description published in the Monograph, the range in
number of oil tubes was not changed from its original statement. The
newer species showed that this range must be changed from *‘'3 to 6
in the intervals,” to read ‘* 1 to 6 in the intervals, and sometimes none
(L. anomata).”

Mr. Jones has established a new genus Cusickia, based upon our
LI. minor. A reexamination of the genus has not shown us any more
than specitic differences between this species and the other species of
Leptotaenia; and Mr. Jones has not called attention to the differential
characters he has in mind.

was a homonym escaped us, though made evident by Schultes’s observa-
tion appended to Sprengel’s description: ‘* Nomen mutandum, cum jam

Jones” has very properly transferred to Cogswellia most of our
species of Lomatium. We append a list of the species of Cogswellia,
with such modification of the list of Mr. Jones as seems to us neces-
sary. We can not follow him, however, in the merging of Euryptera
Nutt. and Cynomarathrum Nutt. under Cogswellia, for the general
reason intimated under Cymopterus above.

APOGAMY IN THE MAIZE PLANT,
By G. N. Couns. ¢

The behavior of some of the varieties of Indian corn, from Mexico
and Central America, with which the Department of Agriculture is
experimenting, exemplifies the tendency of plants to develop ab-
normally when placed under new and unusual conditions. Among the
large number of abnormalities which have come under observation a
case of apogamy appears worthy of special mention, since this phenom-
enon seems not to have been reported in Zea mays.

The abnormality here described was first observed by Mr. R. M.
Meade at Victoria, Texas, in a variety from Tuxtla Gutierrez, Chiapas,
Mexico. Briefly described, it consists in the production of branches
or young plants in the place of the spikelets of the male inflorescence
or tassel. Of this variety, which was grown only at Victoria, practi-
cally all the plants exhibited this character in a greater or less degree.
In other varieties, both at Victoria and elsewhere, a few individual
plants were subsequently found that showed a tendency in this direc-
tion. The production of these apogamous plants is doubtless a mani-
festation of the excessive vegetative growth shown by most of the
tropical varieties of corn when grown for the first time in the United
States. While not as prevalent as the branched ear, staminate flowers
in the ear, and other common eccentricities, these apogamous inflor-
escences are still of sufficiently frequent occurrence to indicate a definite
tendency which if properly interpreted might throw light on the
development of the corn plant.

Plants with this peculiarity have the tassel unusually large. The
lower spikelets are replaced by small plants or branches, many of
which have leaves 20 em. long. The first leaf of these young plants or
branches is undoubtedly a transformed outer glume. Though consider-
ably enlarged, in some cases 20 min. long, it is still easily recognizable
asa glume. The next organs are similar to the early leaves of normal
corn plants. Following 7 or 8 of these leaves a terminal female inflor-
escence can be made out, in most cases distinctly 8-rowed, but in some
cases with 4-rowed branches after the manner of the monstrous ears
occasionally produced at the ends of basal branches or suckers.

In passing upward from the base of the tassel the leaves of these
abnormal branches gradually decrease in size, and about midway on the
tassel there is only a rather unusual development of the lemma (flower-

ing glume) and palet, these inclosing normal stamens. At the tips of
most of the branches of the tassel the spikelets are normal. While
there is a gradual reduction in the size of the branches (see Pl. LX X XV)
there is a very abrupt transition from the last of the pistillate inflo-
rescences to the male flowers with three apparently normal stamens.
It would seem from this that the abnormality is not due merely toa
gradual transformation of the individual floral primordia into leaves
(phyllody), but rather that a change affecting the entire bud takes
place early in its history, causing the young bud to develop as a branch
or young plant instead of producing a normal staminate spikelet.
Furthermore, the number of primordia required for one of these
growths is vastly greater than the number required in a normal
spikelet.

That the inflorescences that terminate these branches or plants
should be pistillate is to be expected from their position on the upper
part of the plant. Branches from the lower nodes of ordinary plants
are the so-called ‘‘suckers,” which terminate in staminate inflores-
cences. Branches from the nodes farther up have the terminal inflor-
escence pistillate, forming the ears, while branches from the inter-
mediate nodes, below the normal ears, usually bear terminal inflores-
cences that contain both staminate and pistillate flowers.

In the axils of the first leaves, which correspond to the outer ¢lumes,
small roots could be seen (see Pl. LX XXIV), and when separated from
the tassel and placed in the ground these apogamous plants took root
and made considerable growth. Though none lived to maturity, they
continued to grow in an apparently normal manner for nearly two
months and produced roots over 1 foot in length.

The production of roots enabling these branches to maintain an inde-
pendent existence would seem to make this a true case of apogamy
similar to that in onions, Agave vivipara, and the Arctic species of
saxifrage. It would only remain for these apogamous plants to effect
a natural separation from the parent plant to make the agreement
perfect.¢

“The definition of apogamy given by Winkler in his ‘‘Parthenogenesis und
Apogamie im Pflanzenreiche,”’ as reviewed in Nature for March 18, 1909, would
seem to exclude all observed cases. The definition is given as follows: ‘‘Apogamy
is the apomictic formation of sporophytes from vegetative cells of the gametophyte.”’

Apomixis is previously defined as the production of a new individual not preceded
by fusion of nuclei. Hence apogamy is restricted to the formation of a new indi-
vidual with cells containing the double number of chromosomes (sporophytes) from .
cells containing the single number of chromosomes (gametophytes) without any
union of nuclei.

Even Yamonouchi’s case of a plant of Nephrodium molle developing from the pro-
thallus and retaining the single number of chromosomes could not be included,
since Leavitt's interpretation of this phenomenon as a case of homcosis seems well
taken and the plant can hardly be considered as a sporophyte.

It seems desirable to retain the term apogamy with its more general application to
cases where a new plant is produced asexually from tissues which normally give
rise to sexual organs.

BRANCH OF TASSEL OF APOGAMOUS MAIZE.

COLLINS—APOGAMY IN THE MAIZE PLANT. 455

While these young plants, being produced in the place of regular
sexual organs, may properly be called apogamous, yet the phenomenon
is closely related to the common forms of asexual reproduction, par-
ticularly to that observed in some of the small varieties of maize that
produce ears at the surface of the ground. Several such cases have
been observed in which roots were developed on the lower nodes of
these ear-bearing branches and the ear was able to continue an inde-
pendent existence after the main plant was dead, the husk leaves act-
ing as assimilating organs. This, it will be noted, exactly parallels
the present example even to the pistillate terminal inflorescence, the
only difference being that of location.

The development of these apogamous plants seems to prove that
even the most highly specialized organs of the corn plant still retain
in latent form the characters of the other parts of the plant.
