A CONTRIBUTION TO THE BOTANY OF THE ISLE OF PINES, CUBA, BASED UPON THE SPECIMENS OF PLANTS FROM THAT ISLAND CONTAINED IN THE HERBARIUM OF THE CARNEGIE MUSEUM UNDER DATE OF OCTOBER, 1916. By O. E. Jennings. (Plates V-XXVIII.) Introductory. The present paper is primarily an annotated list of the planib collected in the Isle of Pines and now contained in the Herbarium of the Carnegie Museum. The list has been supplemented by references to other specimens collected in the Island, wherever records of such specimens ha\« been found in the literature consulted. The greater part of the material studied in the preparation of this list was collected by the writer from May 5 to 26, 1910, while a member of a party sent out by the Carnegie Museum to make col- lections in the Isle of Pines. The party consisted of Dr. D. A. Atkin- son, Mr. J. L. Graf, Mr. G. A. Link, Sr., and the writer. Most of the time was devoted to the exploration of the northern and north- western par.ts of the island. Nueva Gerona was made the base of operations, and the surrounding savannas and the rugged mountains nearby were quite thoroughly explored. On May 7 the writer visited the ridge at Bibijagua in the northeastern part of the island. On May 16 a trip was made to the mouth of the Nuevas River in the northwestern corner of the island. On May 17 a move was made to Los Indios and from this base the surrounding region was explored. On May 21 in company with Mr. Graf the writer visited the Canada Mountains and climbed the highest peak. On May 21 in company with Dr. Atkinson and Col. T. J. Keenan a trip was made on foot to Siguanea. On the following day we crossed Siguanea Bay in a launch to Bogarona, and thence walked about six miles to Caleta Grande on the southern coast. The last two days of our stay on the island, May 25 and 26, were spent collecting in the vicinity of Santa Fe. 19 20 Annals of the Carnegie Museum. The collections made comprised about two thousand specimens, included under about six hundred and fifty field-numbers. In addi- tion to those specimens collected by the writer, there are in the Herbarium of the Carnegie Museum two hundred and ninety-eight specimens collected in the Isle of Pines by Mr. A. H. Curliss in 1903 and 1904, these having been distributed from the New York Botanical Garden a number of years ago as one of a number of sets into which the Curtiss Collection was divided. There are also in the Carnegie Museum a small number of specimens obtained in the Isle of Pines in 1910 by Dr. Jared F. Shafer, of Pittsburgh, and a small collection made by Mr. G. A. Link, Sr.. on the occasion of his sojourn in the island in 1912-1913. The Curtiss Collection was made in the vicinity of Nueva Gerona, that of Dr. Shafer mainly in the vicinity of Columbia and Nueva Gerona, and that of Mr. Link in the vicinity of Nueva Gerona and Los Indios. The most complete set of the specimens collected by the writer in the Isle of Pines, the set which is now in the Herbarium of the Car- negie Museum, together with a duplicate set now in the Herbarium of the New York Botanical Garden, was submitted during the summer of 1910 to Dr. N. L. Britton, Director of the New York Botanical Garden. The specimens were studied by Dr. Britton and Mr. Percy Wilson, many of them being submitted to specialists both at the New York Botanical Garden and elsewhere. The fungi were studied by Professor D. R. Sumstine, of Pittsburgh. To all of these gentle- men I take the present opportunity to extend my grateful acknowledg- ment for their labors, which have facilitated my own. In the preparation of the present report it has been found necessary to reexamine the specimens, because during the past few years great progress has been made in the study of the flora of the West Indies. Much of the credit for this progress belongs to the gentlemen con- nected with the New York Botanical Garden, whose explorations and collections in the West Indies have been extensive and thorough. Dr. Ignatius Urban, of Berlin, assisted by various collaborators, has published much upon the flora of the West Indies in the seven volumes of his SymholcE AniillancB; and in the United States a number of specialists have monographed the North American plants of certain groups, including the West Indian species. An examination of the specimens of the Curtiss Collection shows that quite a number of them, according to the latest literature, belong to species other than Jennings: Contribution to Botany of Isle of Pines. 21 those originally indicated on the labels. As these specimens supple- ment those collected by the writer, it has been thought advisable to include in this list a reference to them also. To facilitate further work upon the flora of this interesting island analytical keys for the species of the various families have been incorporated. These keys have been mainly based on the more readily observable characters of leaves and flowers. In some of the more difficult families the writer has taken the liberty of remodelling certain keys published by other authors, to whom he renders thanks and makes apology, if apology be necessary. The sequence followed in this list is essentially that of Engler's Syllabus der Pflanzenjamilien and the nomenclature is based upon the International Rules of Botanical Nomenclature, excepting as to the "Nomina Conservanda" in matters of priority. Great care has been exercised in the preparation of the synonymy. When synonyms are very numerous a selection has been made, preference being given to those based upon West Indian material, or most likely to be accessible to American botanists working upon W^est Indian plants. Before closing these brief preliminary remarks I wish to express my sense of indebtedness to Dr. C. F. Millspaugh for his kindness in identifying certain of the Euphorbiacece. I wish also to put upon record my appreciation of the services rendered me by my travelling companions during the expedition of 1910, and of the courtesy and hospitality shown us on that occasion by Colonel Thomas J. Keenan, a citizen of Pittsburgh, who has done much to promote the industrial development of the Isle of Pines. To Dr. Jared F. Shafer the Car- negie Museum is indebted for the specimens collected by him, and the writer, in particular, wishes to acknowledge the assistance re- ceived from him in the study of the orchids, some of which he has successfully propagated and brought to flower in his conservatory, where it has been possible to view them from time to time and to obtain additional specimens. To Mrs. O. E. Jennings, for assistance in consulting the literature and in preparing photographs, and to Mr. Sidney Prentice, for his careful drawings of the plates, my thanks are due. I wish gratefully to acknowledge the support and encourage- ment given me by Dr. W. J. Holland, the Director of the Carnegie Museum, which made possible the collection of the specimens and the preparation of the present report. I am indebted to him for his 22 Annals of the Carnegie Museum. editorial revision of the manuscript and the care bestowed upon the preparation of the plates. Finally, I wish to pay my tribute of respect to the memory of my associate, Mr. G. A. Link, Sr., who since the completion of the following catalog passed away on August i6, 1916, under tragic circumstances. By his labors, which already have been referred to, he contributed to the formation of the collections upon which this catalog is based, and the writer will always cherish pleasant memories of the weeks spent with him during the expedition of 1910. Botanical Collections made in the Isle of Pines. Botanical collections have been made in the Isle of Pines as follows*: 1. A collection was made in 1831 by A. H. Lanier, the French consul at Trinidad, Cuba. This collection was studied and reported upon by Achille Richard in the botanical volumes of Sagra's Historia fisica, politica y natural de la Isla de Cuba, Volumes X and XI, 1845 and 1850, Volume XII, plates. Note has been made under various species listed in the following pages when Lanier's specimens have been mentioned by Richard. Richard cites thirty-eight species as having been collected by Lanier. 2. A collection of about one hundred and eighty-five specimens was made by Don Jose Blain, probably about 1849, or 1850, and was studied and listed by Dr. C. F. Millspaugh, Field Columbian Museum, Botanical Series, I, 1900, pp. 425-439. A number of new species based on Blain's specimens were described by Millspaugh. These specimens are noted in the following pages under the various species. 3. A small collection was made at the southwestern corner of the island (Pedernales Poini) by Dr. C. F. Millspaugh, February 16, 1899, when the yacht Utotvana stopped there for a few hours. These specimens were studied and listed, with notes and ciitical reports upon a number of the species, by Millspaugh (Field Columbian Museum, Botanical Series, II, 1900, pp. i-iio. " Plantse Utowanse.") 4. In 1900, from June 27 to July 13 inclusive, Messrs. William Palmer and Joseph H. Riley, under the auspices of the Smithsonian Institution, collected in the vicinity of Nueva Gerona, excepting for a part of two days which Mr. Palmer spent at Manigua, a plantation along the Nuevas River above McKinley, which since has been abandoned. A rather large collection was made by these gentlemen. 5. In the spring of 1901, Mr. A. A. Taylor, principally under the *See also, p. 95, reference to Dr. Wm. Trelease. Jennings: Contribution to Botany of Isle of Pines. 23 auspices of Cornell University, made a collection of about two hundred species, mostly in the vicinity of Columbia. 6. During the winter of 1 901-1902 Dr. \V. W. Rowlee, of Cornell University, made a small collection, adding a few species to the Taylor Collection. 7. From November, 1903, to June, 1904, Mr. A. H. Curtiss made a fine collection, practically all from the vicinity of Nueva Gerona. This collection was studied at the New York Botanical Garden and a number of sets distributed. One of these sets is in the Carnegie Museum and its specimens have been included in the present anno- tated list. 8. In February and March, 1910, Dr. Jared F. Shafer, of Pittsburgh, an enthusiastic collector and grower of orchids, visited the island and made a collection of botanical specimens chiefly in the vicinity of Columbia and of Nueva Gerona. These collections were turned over to the Carnegie Museum. Dr. Shafei brought to Pittsburgh quite a number of live orchids, most of which grew and flowered in his con- servatory. Dr. Shafer's specimens are reported upon in the present list. 9. About two thousand specimens (about six hundred and fifty field-numbers) were collected from May 5 to May 26, 1910, by the writer and they constitute the basis of the present report. The main collection is in the herbarium of the Carnegie Museum, and a number of smaller sets have been distributed in exchange, the next largest set being now in the Herbarium of the New York Botanical Garden. 10. A collection of about sixty specimens was collected by Mr. G. A. Link, Sr., during May and June, 1912, in the vicinity of Nueva Gerona, and in November, 1912, at Los Indios. These specimens are in the herbarium of the Carnegie Museum, and have been listed in the present report. * 11. A large collection has been recently made by Dr. N. L. Britton, Mrs. Britton, and INIr. Percy Wilson, of the New York Botanical Garden, the expedition occupying the period from the middle of February to the latter part of March, 1916. In a recent account of this trip Dr. Britton notes that the flora of the island has been repre- sented up to this date by specimens in the various collections to the number of seven hundred and forty species. Writing of the recent collection he notes: "Our collection aggregates one thousand six 24 Annals of the Carnegie Museum. hundred and fifty-seven numbers, and, taken with the others, indi- cates that the total natural flora of the island is not less than one thousand five hundred species." — Britton, Journal of the New York Botanical Garden, XVIII, 191 6, pp. 64-71. Publications relating to the flora of the Isle of Pines.* The following list includes the titles of all publications relating to the flora of the Isle of Pines, so far as known to the writer. No mention has been made in this list of various popular articles, which have little or no botanical value: 1. Richard, Achille. In Sagra, Historia fisica, poJtica y natural de la Isla de Cuba, X, 1845, XI, 1850, and XII, plates, no date. Richard, under various species in these volumes, refers to the Lanier Collection made in the Isle of Pines in 1831, by noting " Cresctt in insula Pinorum." A few of the plates in volume XII were made from Lanier's specimens. 2. The collections made about i860 in the Isle of Pines by Don Joss Blain were reported on by Dr. C. F. Millspaugh, " Plantce Insulcs Ananasensis." Field Columbian Museum, Botanical Series, I, 1900, pp. 425-439- This report consists of an annotated list, with discussions as to the botanical relationships or characteristics of a number of the species, and descriptions of a few species proposed as new. Don Jose Blain is mentioned in one of Charles Wright's letters to Asa Gray as a botanical enthusiast of some ability. 3. Under the title "Plantce Utowance," Dr. C. F. Millspaugh pub- lished an annotated list of the plants collected during a West Indian cruise of the yacht Utowana in the winter of 1 898-1 899. — Field Columbian Museum, II, 1900, pp. i-iio. During the course of this cruise, a stop of a few hours was made at Pedernales Point, on the southwestern corner of the island, February 16, 1899, when a small botanical collection was made. Millspaugh's list contains the names of a number of species which have not otherwise been reported for the Isle of Pines. 4. Rowlee, W. W. " Conditions of Plant Growth in the Isle of Pines."

H. Curtiss Collection. Volumes V, VI, and VII of the Symbolce Antillance also contain a number of references to plants from the Isle of Pines, mainly from the Curtiss Collection. Descriptions of new, and reports as to the distribution of previously described, species are given. 7. Britton, N. L. In the Bulletin of the Torrey Botanical Club there have appeared at irregular intervals for a number of years past a series of articles, entitled "Studies of West Indian Plants." In these articles Dr. Britton has dealt to a limited extent with specimens col- lected in the Isle of Pines, giving descriptions of a few new species. 8. North Aynerican Flora. In certain recent numbers of the North American Flora there are to be found references to the Isle of Pines, either in the paragraphs on general distribution of the species, or, in a few cases, new species are proposed based on specimens from the Isle of Pines.

Physical Features. For the purposes of the present paper it suffices to say that the Isle of Pines lies about sixty miles south of the west central portion of Cuba, somewhat farther west than Havana, and has an area of about eight hundred square miles. ^ The Island consists, generally speaking, of a northern and a southern part, separated by a fresh- water swamp which, to the east and west, passes into salt-water marshes and mangrove swamps, the latter eventually opening out into wide bays. The northern portion of the island is roughly elliptic in shape averaging about twenty-live miles in diameter. It consists of a low-lying and rather level plain, from which, in the noitheastern part of the island, the Caballos Mountains rise to a height of about one thousand feet. The mountains consist of crystalline limestone lying in thick strata which dip steeply to the east-northeast, the general trend of the ridges being from northwest to southeast. A short 1 See in this connection the general discussion of the physiography and geology of the island in Jennings, "Notes on the Ferns on the Isle of Pines," American Fern Journal, I, 1911, pp. 129-136 and "A Note on the Geology of the Isle of Pines," Journal of Geology, XXI, 1912, pp. 367-369; Britton, "The Natural Vegeta- tion of the Isle of Pines, Cuba," Journal of the New York Botanical Garden, XVIII, 1916, pp. 64-67; also (mainly contributed by the present writer) the discussion of the general natural features and vegetation in Todd, W.

Jennings: Contribution to Botany of Isle of Pines. 27 distance to the west of these mountains are the Casas Mountains, slightly lower, but very similar in their general features. On the northeastern coast is. a still lower ridge (Bibijagua) of the same char- acter as the other two. In the southwest, the Canada Mountains rise to about one thousand feet (985 feet, Jennings; 1015 feet, Britton), being composed of an impure quartzose mica-schist, with some sandstone, and they have generally gentle slopes. The mountains and hills in the south-central and southeastern parts of the island were not explored by me, but according to Britton, /. c, they are partly limestone and partly sandstone and schist. The plains of the northern part of the island, from which rise the hills and mountains just mentioned, are gently undulating, reaching an elevation of about two hundred feet above the sea in the central portion whence the drainage systems radiate towards the sea with broad, gently sloping valleys. This plain is mainly of subaerial erosion, but around the bases of the northern mountains there is a fine series of wave-cut cliffs at about fifty or sixty feet above the present sea-level. The outer margins of the plain mostly slope gently into the sea and marginal coastal deposits are of considerable extent- There appears to have been in geologically recent times an eleva- tion sufficient to enable the streams to cut down steep channels, at least in their lower courses, and subsequent depression has converted! the lower parts of the rivers into deep inlets which are subject to tide- water for several miles above their outlets. The soil of the plain in the northern part of the island consists mainly of a yellowish-red or brownish-red (iron-stained) gravelly clay, known as the "Mai Pais" gravel. This soil is evidently residual and has been derived by subaerial erosion from underlying marbles and schists. In depressions, however, and especially on the low plain below the level of the ancient sea-cliffs, the soil is more largely a yellowish or grayish sandy loam, while towards Los Indies in the western part of the island the soil becomes chiefly sand, or sometimes a pure white, angular, quartz gravel, with more or less iron ore (li- monite). The part of the island south of the swamps consists of a rather narrow area convex to the south and extending out to the west and northwest in a long curve. This component of the island, known locally as the "South Coast," is essentially a low plain of coralline (or partly aeolian) limestone, rising somewhat to the south, where it 28 Annals of the Carnegie Museum. faces the sea in a more or less prominent, perpendicular, and ex- tremely jagged cliff, broken here and there by inlets and sandy beaches, but constituting, altogether, a dangerous coast with but very few- harbors. This "South Coast" plain has a very scanty, but yet rich, dark, loamy soil filling the holes and pockets in the jagged surface of the rock and supporting a hardwood forest with many large trees. The climate of the island is, of course, oceanic and equable. The extreme annual range of temperature lies between 50° and 100° Fahr., the temperature duiing May, 1910, ranging from 82° to 92° during the warmest part of the day, the minimum rarely falling to 70° at night. The water taken from the wells and springs usually registered between 70° and 80° Fahr., while the temperature of the ocean water on the beaches was 8o°-82° Fahr. The season is sharply divided into a wet season and a dry season. The rains, frequently torrential thunderstorms, occur from May or ■early June to about November, then occur scattering showers until early spring, followed by a severe drought till the rains begin again. The drought must be ecologically a very important factor in deter- mining the character of the vegetation of the island, particularly where associated with extensive grass and brush fires, as appears to ."have been the case at least since the occupation of the island by Europeans. Plant Associations. 'The vegetation of the various parts of the island is very closely related to the major features of the physiography and geology as outlined above. Briefly, the following ecological groups are out- standing features of the landscape. For purposes of uniformity the nomenclature adopted for these groups is essentially that of Harshberger's Phytogeo graphic Survey of North America. I. The Mangrove Forest Formation. This formation consists of a low thick forest of halophytic shrubs fringing the low coasts of the island and extending inland, particularly along the lower courses of the rivers, up to the limits of brackish water. Towards the mouth of the Nuevas River, in particular, the man- groves have been instrumental in catching and retaining river sands and coastal debris to the extent of adding considerably to the area of the island. The margin of the mangrove forest nearest the water consists, in Jennings: Contribution to Botany of Isle of Pines. 29 the Isle of Pines, of Rhizophora Mangle but, towards the land, this species is mainly supplanted by the White Mangrove, Avicennia nitida. Under these latter trees are large tussocks of Acrostichiim aur.eum, the leaves of this fern often reaching a height of five or six feet. In the clumps of Acrostichiim, but apparently rarely forming tussocks independently, are great clumps of Nephrolepis biserrata. The -ground under the Avicennia is often covered almost completely by Batis mantima, this species constituting there a distinct society. 2. The River-hank Forest Formation. This forest constitutes a veritable jungle along the banks of the rivers where the water is non-saline. Among the various trees of this forest some of the most prominent are the royal palm (Roystonea regia), the majagua {Hibiscus tiliaceus), and the alligator-apple {Annona paliistris). There are a large number of smaller trees, shrubs, and herbaceous plants competing vigorously for space, among these being Lonchocarpiis latif alius, Hirtella mollicoma, Eugenia fara- moides, Ternstrmmia obovalis, Dendropanax cuneifolium, Xylopia grandiflora, Matayba oppositifolia, Cyrilla racemiflora, Cecropia peltata, Miconia tomentosa, and Miconia prasina. This forest extends in an ever narrowing fringe up the rivers and terminates in a scattering fringe, or in a series of individuals, along the banks of periodically dry arroyos. This constitutes a more or less distinct vegetational unit, which may be termed the "Arroyo Formation." 3. The Arroyo Formation. This vegetation is characterized best, perhaps, by Chrysobalanus pellocarpus, the Coco-plum. Accompanying this species are various other shrubs and smaller plants, many of them common in the river- bank forest. This is the habitat of the tree-fern, Alsophila myostiroides and of A diantum fragile and Adiantiim cristatum. 4. The Freshivater Lagoon Formation. While there are apparently some good examples of this formation in the southern portion of the island, little opportunity was afforded to study them. At Los Indios the river forms an ox-bow approaching lagoon conditions. Here were Castalia ampla and Uiricularia spir- andra, and the small pond about one and one-half miles east of Nueva Gerona also shows this formation. 30 Annals of the Carnegie Museum. 5. The Mud-swamp Formation. Probably the nearest approach to this formation in the region explored by the writer is the muddy margin of the pond about one and one-half miles east of Nueva Gerona. One of the most striking plants is Odontosoria Wrightiana forming large clumps or tussocks, much in the same manner as does Osmunda cinnamomea in our North- ern swamps. 6. The Strand Formation. The strand formation is well developed near Bibijagua, and at that place it may be seen to consist of three well-defined members, as follows: (a) The Ipomma Pes-Caprce Association characterized by the beach morning-glory {Ipomcea Pes-Caprce). (See Plate V.) (b) The Suriana- SccBvola Association characterized by Suriana maritima and Sccevola Plumierii. (c) The Coccolohis uvifera Association. The sea grape is some- times supplanted in such locations by the poisonous Metopium Brownei, as at Siguanea Beach. 7. The Salt-marsh Formation. Very little salt-marsh was seen on the Isle of Pines. Near the mouth of the Nuevas River there was a small area of it and some of the halophytic swamp between the northern and southern portions of the island probably should be so classed. Photographs taken up the channels of this swamp by Dr. D. A. Atkinson show Mariscus jamaicensis to be apparently a characteristic member of this salt marsh. Distichlis spicata is also a member of this formation. 8. The Fresh-water Marsh Formation. This formation is probably represented in the middle portions of the swamp mentioned above, but it was not personally studied. 9. The Sand-plain Formation. Near the mouth of the Nuevas River there are areas probably derived from a salt-marsh by the accumulation of loose sand. This is perhaps best characterized by Andropogon tenuispathaceus and includes Opuntia. 10. The Savanna Formation. This is one of the most prominent and characteristic formations on the island, occupying most of the lower areas of the plain, excepting Jennings: Contribution to Botany of Isle of Pines. 31 where too sandy. It is preeminently characteristic of the " Mai Pais " gravels near Nueva Gerona, and is itself characterized by a con- siderable number of species of scraggly shrubs and palmettoes, asso- ciated rather openly on a more or less grassy plain. The most char- acteristic of these shrubs are Byrsonima crassifolia, Miconia delicatula, Tahehuia lepidophylla, Brya Ebenus, Curatella americana, the large- leaved and mullein-like Byrsonima verbascifolia, and the common palmetto, perhaps the most characteristic species of the savanna, Accelorraphe Wrightii. Probably these savannas largely owe their existence, at least their very open character, to the grass and brush fires which formerly were of common occurrence during the dry season. If left undisturbed, there can be little doubt that much of the savanna would eventually pass more or less completely into the Open Forest Formation. 11. The Open Forest Formation. This consists of an open pine forest with palmettoes and a sparse undergrowth of many of the species characteristic of the savanna. The pine is Finns carihcea and the formation occupies the higher and drier parts of the "Mai Pais" gravel plain, towards Los Indios merg- ing into the pine-barren forest. The open forest formation, as noted above, would very likely succeed much of the savanna were it not for man's use of the trees and for the fires. 12. The Pine-barren Formation. I have seen fit to distinguish between this open pine forest, of the white sands and gravels of the Los Indios region, and the "Open Forest Formation." In the pine barrens the soil shows its acid char- acter and the undergrowth is not to any large extent composed of species characteristic of the savanna. These lower plants constituting the undergrowth are Pachyanthus cubensis, Pachyanthus ovatus, Kalmiella aggregata, Miconia delicatula, Polygala uncinata, Xolisma myrtilloides, Pinguicula filifolia, Stenor- rhynchos sqiiamulosus, Tetramicra Eulophice, etc., altogether a con- siderable number of interesting plants not found elsewhere on the island but some of them occurring also in Pinar del Rio Province, Cuba. 13, The Tropical Forest Formation. This is the hardwood forest formation covering the crystalline limestone hills and ridges and the limestone plain constituting the 32 Annals of the Carnegie Museum. southern portion of the island. The forest is dense and contains many vines and epiphytes. On the hills and ridges near Nueva Gerona this forest is characterized by the large-trunked Bomhax emarginata, the cabbage-palm {Sabal parviflora), Casearia sylvestris, Trichilia hirta, Amyris balsamifera, Cordia glohosa, etc. On open exposed knobs and cliffs Agave papyro- car pa, and Plumiera emarginata become conspicuous. The forest on the limestone plain of the "South Coast" is quite similar but with a larger proportion of leguminous plants. Here occur Bauhinia, Lysiloma hahamense, etc., and towards the interior, especially where burned or where lumbered, there are areas which may be termed "chaparral." 14. The Chaparral Formation. This formation, as exemplified near Hato, in the interior of the peninsula between Bogarona and Caleta Grande, is a dry forest of small -leaved trees of low stature, and with a rather large proportion of thorny species. Here occur Bucida Buceras, Tecoma pentaphylla, Pithecolohium arboreum, Lysiloma bahamense, Ouratea agrophylla, etc. 15. The Sea-cliff Formation. Wherever the mountains or the limestone plains form a cliff along the coast, there appears a very characteristic fringe composed of a palm, Thrinax Wendlandiana, and the peculiar clubby, branched Apocynaceous plant, Plumiera emarginata, accompanied by a number of other less conspicuous species, these constituting altogether what may be termed the Sea-cliff Formation. Good examples of this vegetation are to be seen along the steeper seaward slopes and cliffs of the Colombo and Bibijagua mountains. Owing to the brief time spent in the Isle of Pines no attempt was made to study the marine formations along the coasts, although the few observations which were made indicated a rich flora.

These specimens, perhaps referable to A. dentatum, have been listed separately while undergoing further investigation. The stipe and rachis are sparsely stipitate-glandular with dark brown glands, often several on the petiolules, which latter are slightly more distinct than in the material from Florida and Cuba which appears to be referable to A. dentatum. A smaller specimen in the Herbarium of the Carnegie Museum from the Guttenberg collection from Jamaica (no data) appears to be identical with Mr. Link's collection. 45. Blechnum occidentale Linnaeus.

The specimen collected by Mr. Link, is a carpellate plant with a fine ripe cone. The cone is oblong-ovoid, 5 cm. long by nearly 3 cm. thick, mounted on a stout peduncle which is 3 cm. long and 4 mm. thick, and densely and softly brownish-pubescent. The cone con- tains about twenty carpels, the peltate flat-topped scales being densely brown pubescent, hexagonal, in lateral diameter about 12-15 mm., the vertical dimension about 6 mm., and the middle portion being marked off by a light colored line and somewhat sunken. The apex of the cone consists of a stout point about 5 mm. long. Family PINACE^. Key to the species enumerated.

Jennings, No, 685; Sante Fe, February 11, 1903, George R. Shaw. General Distribution: Southern Florida to Georgia and Mississippi, the Bahamas, Cuba, and the Isle of Pines. In the Bulletin of the Torrey Botanical Club (XXX, 1903, pp. 106-108.) \V. \V. Rowlee has published some notes on the pines of the Isle of Pines, including in these notes descriptions of a new species (Pinus recurvata Rowlee) and a new variety [Pinus cubensis var. anomala Rowlee), also recording the occurrence on the island of Pinus cubensis Grisebach. Pinus caribcea is the common pine which probably formerly covered almost completely the " Mai Pais" gravel plains, the sandy or gravelly (quartzose) plains in the western and southwestern parts of the island, and the gentle slopes and rounded tops of the mica-schist hills and mountains in the south -central and southwestern parts. At the time of the writer's visit in 1910, the view from the top of the Canada Mts., looking to the west and northwest over the pine-barrens, was as over a sea of light green, broken here and there in the hazy distance by the darker green jungle and mangrove forest along the moist valleys and near the coast. 65.

Rowlee's description of Piniis cubensis var. anomala {Bulletin of the Torrey Botanical Club, XXX, 1903, pp. 106-108), as collected by him at Jucaro Landing in 1901, is as follows: "Tree 6-9 m. high. Slender needles 3, bracts 6-8 mm. long, green and remaining on the shoots the first season, resembling the leaves of a spruce." Family TYPHACE^. 66. Typha angustifolia Linnaeus.

The hairs accompanying the pistillate flowers do not have the club- shaped tips which are supposed to indicate the distinctive character of Typha domingensis Persoon, and, it appears probable that there are good reasons for reducing the latter species to the position of a form of T. angustifolia, or even to pure synonymy, as has been done by Wilson, in the "North American Flora," XVII, 1909, p. 3.

This species, now reported to extend from " Delaware to Florida, Texas, and Mexico" ("North American Flora," XVII, 1909, p. 57), has probably been confused with typical Sagittaria lancifoUa, as to a number of West Indian records. It is quite distinct from S. lancifoUa, however, in the specimens from the Isle of Pines. A brief description of the specimen from the Isle of Pines follows: Jennings: Contribution to Botany of Isle of Pines. 51 Leaves emersed, arising from a strong horizontal rhizome, the petioles about 15 to 20 cm. long, the blades about 6 to 10 cm. long by 3 to 5 mm. wide, thick, pseudo-penninervate, with usually 5 nerves, the apex narrow but obtuse, scape simple, 6 to 6.5 dm. tall, the whorls of the inflorescence 4 to 7 in number, peduncles of the stami- nate flowers 1.5 to 2 cm. long, slender, ascending, those of the pistillate flowers about 8 to 17 mm. long, somewhat thicker than those of the staminate flowers, bracts ovate, acute, strongly veined, dorsally minutely papillose, 8 to 13 mm. long, sepals obtuse, about 6 mm. long, petals about 1.5 cm. long, anthers slightly shorter than the very sparingly pubescent filaments, mature achenes rounded-obovate, about 2 mm. long by 1.2 mm. wide, margined all around by a lighter colored wing, the beak about 0.5 mm. long, spreading horizontally from the apex of the achene, but with the extreme tip usually upturned.

This is the common palmetto of the savannas of the northern part of the island, where it grows either singly or in clumps. The plants reach a height of fifteen feet, or occasionally more. The writer has followed Sargent, "Trees and Shrubs," II, 1913, p. 119, in the synonymy of this species. Sargent distinguishes between this species and Accelorraphe arborescens of Southern Florida, the latter species not having the petioles strongly toothed throughout their whole length as in A.

Its trunk is straight, smooth, reaching perhaps a height of thirty feet, but very slender, usually not over two or three inches in diameter. The leaves are borne in a close cluster at the apex, very soon dropping when dead, rarely reaching a diameter of two feet, and being borne on smooth slender petioles. The palm is fairly common on the "Mai Pais" gravel of the savannas in the northern part of the island, reaching also the sandy pine-barrens around Los Indios. Some fine specimens were seen on the upper slopes (mica-schist) of the Canada Mts. See Plate VII. 179. Copernicia Curlisoii Beccari. Copernicia Curlissii Beccari, in Webbia, II, 1908, p. 176.

This is the large-leaved "cabbage palm" of the Isle of Pines. It is quite largely used for purposes of thatching, and trees with a full crop of leaves are difficult to find. It occurs not only upon the savanna but also upon the slopes of the crystalline-limestone hills and moun- tains in the northeastern part of the island. 86 Annals of the Carnegie Museum. i8i.

General Distribution: Southern Florida, the West Indies, and Central America. The Royal palm is a beautiful object, its tall white trunk usually standing sharply outlined against the other colors of the landscape. The trees occur in the moister spots along the streams and in the lower spots on the savanna. They commonly form clumps or small groves about the bases of the Casas and Caballos Mts., the roots here evidently reaching the moisture which drains away from the mountains. See Plate IX. 183. Cocos nucifera Linnaeus. Cocos nucifera Linnaeus, Species Plantarum, 1753, p. 1188. The coconut palm is commonly cultivated in the Isle of Pines. Along the "South Coast" at Caleta Grande, as well as along the coast near Bibijagua, specimens were seen which, from their location, would indicate that they had not been planted there. The coconut palm, now widely distributed through the tropics, probably had its origin in the tropics of America. See Cook, "History of the Coconut Palm in America," Contributions from the United States National Herbarium, XIV, 1910, pp. 271-342.

My collection embraced only sterile specimens, but the leaf- and stem-characters agree so closely with those given for Philodendron Krebsii that I have no hesitation in referring the specimens to that species. The petiole is little or not at all sheathing at the base, and is sub- terete, slightly flattened on the upper side, reaching a length of 8-10 cm. The lamina is 10-18 cm. long, the upper two-thirds being oblong, about 3-4 cm. wide, with an abrupt acumination, the basal one-third of the lamina being rounded, rather deeply cordate, 6-8 cm. wide, the basal three or four pairs of the primary veins being slightly stronger than the secondary veins. 185.

This plant agrees very closely with the description of the Cuban plant, although the leaves are shorter, about 3-5 cm. instead of 8 cm. and the peduncles are shorter, being at the longest 13 cm. instead of 30 cm. This may possibly be found to be a variety of P. seslerioides, but a larger series of specimens are needed for study before such a decision can be made.

Plant perennial (?), stem ca^spitose-branched up to 3 cm. high, leaves densely tufted towards the top of the stems and branches, linear from a dilated, subamplexicaul, ciliate base, rather thick, rigid, finally somewhat obtuse, 6-8 mm. long, peduncles solitary in the axils of upper leaves, rigid, 3-costate, soon glabrate, 1.5-2 cm. long, sheaths about 3 mm. long, the lamina about 4 mm. long, linear-acuminate, the heads broadly obconic, about 2-4 mm. in diameter, hairs of the flowers acute, nearly hyaline, outwardly smooth, nodose at the septa, the interior surface of the wall scarcely at all granulose. Planta perennis (?), caule caespitoso-ramoso usque ad 3 cm. alti- tudine, foliis prsesertim in apice dense confertis, e basi dilatata sub- amplexicauli ciliata linearibus, crassiusculo-rigidis, demum obtusius- culis, 6-8 mm. longis, medio vix I mm. latis; pedunculis in axillis foliorum superiorum solitariis, rigidulis, 3-costatis, mox glaberrimis, 1.5-2 cm. longis; vaginis circiter 3 mm. longis, laminis circiter 4 mm. longis, lineari-acuminatis; capitulis lato-obconicis, circiter 2-4 mm. diametro, pilis florum acutis, paene hyaline, extus laevibus, ad septa nodulosis, intus vix granulosis. Type: On gravelly soil in the pine-barrens one mile north of Los Indios, May 19, 1910, 0. E. Jennings, No. 387. This plant is evidently to be regarded as a derivative of the Cuban PcEpalanthiis alsinoides. It was found growing on the coarse, glisten- ing, white quartzose gravel in the pine-barrens north of Los Indios, and it was associated with a number of plants with decided inclina- tions towards a habitat of acid soil: Pinguicula filifolia, Kalmia sp., Xyris ambigua. The variety differs from the typical species in that it has leaves only half as long as the latter, the peduncles only about one-third as long, and the hairs of the flowers scarcely or not at all granulose on the inside surface of the cell-wall. In most of the other characters the variety agrees well with the species. The flowers were too far past maturity to be studied satisfactorily, but were seen to be about 1.8 mm. long, the three outer segments i mm. long, obcuneate, the truncate apex piliferous and erose, the inner segments as long, united into a slender tube with the small lobes and, after maturity, strongly infolded. 90 Annals of the Carnegie Museum. 190.

This was identified as H. juncea Smith, but as the writer under- stands that species it is far different from the plant found in the Isle of Pines. H.juncea, in the form in which it occurs in our South- ern States, has far more filiform-linear leaves. The plants from the Isle of Pines have the free portion of the perianth-parts about i cm. long, the corms semiglobose and often 1.5 cm. thick, and the inner perianth segments only about three-fourths as wide and three-fourths as long as the outer ones. Growing together with this species in the dry open fields just south of Sante Fe, and apparently related to it, were similar but considerably smaller plants, the leaves being usually less than 3 mm.

The general color of the fresh flowers was yellowish with a purple tinge: the sepals and petals were yellow, often shading to brownish; the lip was a creamy yellow, usually with more or less of a crimson spot and rather prominently marked, especially towards the base, with purple lines. The general habitat of the species is the forks of trees. The plant apparently flowers most profusely at a height of about ten or fifteen feet above the ground. The species is not confined, however, to such habitats, but it occurs on palm trunks, posts, etc., where it may receive little or no shade. Type. — Near Nueva Gerona, May 12, 1910, 0. E.

The flowers are apparently somewhat smaller than those of E. fucatum. E. tampense Lindley is also very closely related to E. obcordatum, but the flowers of E. tampense are much larger than those of the Isle of Pines species. 226. Epidendrum brevifolium sp. nov. (Plates X and XIX.) Epiphytes. Pseudo-bulbs aggregated, about 20-30 in number, ovoid, somewhat compressed, at the apex 2- (i-3)-leaved, 3-5 cm. long, leaves coriaceous, erect-spreading, narrowly oblong-ligulate, somewhat obtuse, conduplicate at the base, 5-9 cm. long, 1.2-2 cm. wide, peduncle simple or laxly sparsely branched, 3-4 dm. long, above laxly few-flowered, much longer than the leaves, pedicels slender, with the ovary 2-2.5 cm. long, bracts broadly triangular, acute or somewhat obtuse, the lower up to 10 mm. long, sheathing, the upper about 3-4 mm. long, flowers spreading, with spreading segments; sepals narrowly obovate, 2-2.5 cm. long, 6-8 mm. wide, acute to somewhat obtuse, 7-nerved, petals narrowly oblong spatulate, some- what obtuse, 2-2.5 cm. long, 5-7 mm. wide, the lip short-clawed, 25-30 mm. long, about 20 mm. wide, deeply three-lobed, the lateral lobes 12-15 i^rn- long, oblong, subfalcate, obtuse, erect, the apex somewhat recurved, the middle lobe shortly clawed, broadly rounded, at the base broadly cuneate, at the apex deeply emarginate, the margin crisped, the disk bicarinate below with fleshy ridges, column triquetrous, 10-12 mm. long, canaliculate along the front side, the apex with membranaceous, incurved, rounded auricles.

Flores purpureo- fusci; labello albo, inferne lineis numerosis radiantibus purpureis ornato. This species dififers from Epidendrum plicatum Lindley in that the former has a deeply emarginate lip, the sinus being 6-8 mm. deep and cutting the median lobe about one-third across. E. hrevifolium is most nearly related to Epidendrum phosniceum Lindley but differs from the latter particularly in the much shorter leaves, which in E. phosniceum are 25-30 cm. long. E. hrevifolium has also fewer flowers, longer pedicels, the base of the median lobe of the lip not truncate but broadly regularly narrowed, while the color of the lip is white marked below with purple lines, not purplish-violet nor crim- son as described for E. phceniceum. The flowers had no odor. Abundant on palm trunks in the Los Indios pine-barrens. Type. — Pine-barrens near Los Indios, on palmetto trunk, May 17, 1910, 0. E.

Collected but once, in thicket at side of a pool near the base of Caballos Mts., east of Nueva Gerona, May 9, 1910, 0. E. Jennings, No. 168. General Distribution: Cuba, the Isle of Pines, and Mexico. Although first identified with Piper elongatiim the specimen is certainly not of that species. The specimen has rather densely vil- lous branches, the leaves are rather densely and more or less ap- pressed-villous below, eventually smoothish but minutely scabrous above, there are four stamens, the bracts being villous above, and the ovary is sub-tetragonal, almost three-angled, and at first hirtellous on the top. The leaves reach a length of about 16 cm. and a width of 5 cm., and when mature become sub-lustrous above. After an examination of specimens in the herbarium, it becomes plainly evident that many of the narrower-leaved specimens from Cuba and Mexico belonging to this species have been erroneously labeled ''Piper aduncum L."

Among the many varieties and subvarieties described by Warburg, op. cit., pp. 471-479, the specimen from the Isle of Pines can be best referred to sub- variety subcordata, as indicated, but there is considerable difference be- tween this specimen and the No. 6ogo, Sintenis, from Porto Rico, which Warburg cites as of this subvariety. The Isle of Pines specimen has much smaller leaves, the largest being only about 6.5 cm. long by 3.5 cm. wide, the petioles are shorter, and the base is more decidedly cordate. 242.

The writer has not seen the Blain specimen reported by Millspaugh as C. retusa, but there is a strong possibility that the specimen here referred to {Jennings, No. 6j6) is the same species. Specimens such as the Porto Rican Sintenis, No. 3945, referred by Lindau (Symbolae 112 Annals of the Carnegie Museum. Antillanae, I, 1899, p. 227) to C. laurijolia, represent a form having a large leaf with an obtuse base and a strong wide petiole, very much in contrast to the specimens from the Isle of Pines. The latter speci- mens have leaves up to about 7 cm. long and 2.5 cm. wide, acute or even acuminate at the base, while the petiole is comparatively slender. Florida plants referable to Lindau's C. Curtissii are, in fact, very closely related to the specimens from the Isle of Pines, as to leaf characters. Family AMARANTACE^. Key to the Species Enumerated. Leaves alternate.

The variety was said to be known in the Isle of Pines as " Ycaco negro" and it was described by Richard as having smaller leaves and flowers, with the flowers in fewer num- bers, so that the plants would answer very well to the description of Meyer's Chrysobalanus pellocarpus. 278.

Jennings, No. SSQ. General Distribution: Cuba, Isle of Pines, Jamaica, Porto Rico, Haiti, Mexico, and Central America. Together with Thrinax Wendlandiana and Bucida Buceras, this species forms, in large part, the sparse and low forest growth (chapar- ral) near Hato, in the interior part of the peninsula which runs out from the island to the southwest and is comprised in the term "south coast." In this particular locality the original forest had probably been removed and the chaparral can perhaps be regarded as an inter- mediate stage in the plant successions which would eventually result in the establishment of a denser forest of taller hardwood species. The specimens from the Isle of Pines, almost without exception, have fewer pinnae (usually four pairs) and fewer leaflets to a pinna (usually less than twenty pairs) than are stated for the species in the older descriptions. 280.

The specimens secured at Sante Fe were borne on a large spreading tree about forty feet high, with rather light green foliage somewhat resembling that of Fraxinns americana. The flowers borne in dense racemes about two or three inches in length, were light yellow in color and faintly but not very pleasantly scented. Note. — Lonchocarpus sericeus Humboldt, Bonpland & Kunth, was reported as growing in Cuba and the Isle of Pines by Achille Richard, in Sagra, "Historia Fisica, Politica y Natural de la Isle de Cuba," X, 1845, p. 179. The Isle of Pines was included in this distribution on the basis of specimens collected there by Lanier in 1831. The writer is not satisfied that Lonchocarpus sericeus is properly to be included in the list for the Isle of Pines. Richard's description for that species is mainly as follows: Branches, petioles, and peduncles densely tomentose-sericeous; leaflets 7-11, oval, acuminate, the base obtuse, above pubescent, below densely tomentose-sericeous; racemes terminal, numerous, as long as or longer than the leaves; petals externally sericeous; legumes short, 1-3-seeded, densely fulvous- velvety. 315.

Distribution: In fields, Guiana, Venezuela, Brazil, and Isle of Pines. Curtiss's plant was distributed (No. 448, West Indian Plants) under the name Clitoria cajanifolia, and subsequent collections from the Isle of Pines seem to have been labeled the same ( = Clitoria laurifolia), but a careful examination of various descriptions have led the writer to believe that the plants should be called Clitoria guianensis. The plants have a thick woody taproot and, from the crown, are sent up erect branches to a height of from 5 to 20 cm., bearing in the upper axils one or two flowers. The flowers are quite striking objects, the standard often reaching a length of 6 cm. and a width of 5 cm., the color varying from blue to rose or fading to almost white. The leaflets are narrowly oblong, about 8-12 mm. wide and from 6-10 cm. long, sometimes longer in vegetative shoots. The leaves are sparingly pubescent on the veins beneath, strongly reticu- lated, minutely glandular on both sides, paler and somewhat glaucous beneath. The apex is obtuse but mucronulate. The pods are about 4 cm. long by 6 mm. wide, their valves being strongly costate, the apex tapering into a beak about 5-8 mm. long. The writer has notseen Blain'scoUections, now in theHerbarium of the Field Museum, but it is probable that the specimen reported by Mills- paugh for the Isle of Pines, Blain, No. 2Q, is also Clitoria guianensis. 320.

General Distribution: Cuba, the Isle of Pines, Jamaica, Haiti, St. Kitts, Guadeloupe, Martinique, St. Vincent, Panama, and Brazil. A vine, climbing in the dense jungle to a height of eight or ten feet. The pods (on our specimen) are borne, four together, on a long hanging peduncle. The largest pods are 20 cm. long, 5 cm. in width, and on one edge ridged with two somewhat scalloped flanges. The valves are irregularly ridged, and are more or less brown-velvety with fine stiff hairs, which, to the skin, are very irritating and some- what poisonous, evidently in this respect resembling closely the notori- ous "cowhage" {Mucnna pruriens). The seeds are borne one to four in a pod and are a dirty yellow-brown, shading towards the raphe into a lighter ashy color, the raphe itself being black and extending about four-fifths the way around the seed. The beans are about 2.5 cm. in diameter, almost orbicular, and about 1.5 cm. in thickness. 326. Calopogoniuin caeruleum Desvaux.

This species is remarkable for the great variation in the shape of its leaves. In the savannas and open woods of the northern part of the island it grows as a low shrub with oval, oboval, or oblong leaves, while in the southern part of the island, on the coralline lime- stone of the "South Coast," it grows as a vine and its leaves there become very narrowly lance-oblong or even linear. The writer is not yet prepared to claim that the differences noted are due to the differ- ences in the soil, but our collections would seem to indicate such a relationship.

General Distribution: Isle of Pines, Trinidad, northern South America. The specific name verbascifolia is especially well chosen. The plants grow scattered about the open savanna with large mullein- like leaves arising in groups of one to several, rosette-like, from the apex of a short, gnarled, woody stem, which is often prostrate or at least ascending but a few inches above the ground. At a short distance the resemblance to rosettes of Verbascum Thapsiis is particularly striking. 362. Byrsonima coccolobaefolia Humboldt, Bonpland, & Kunth.

The plants, as seen growing on the savanna near Santa Fe, were small bushy trees rising to a height of ten feet, with much the general habit of growth and appearance of Curatella americana (the "Sand- paper Oak"). The flowers generally are white, tinged with pink, the stamens being yellow. Note. — Malphigia urens Linnaeus, and M. setosa Sprengel, Blain, Nos. 37 and 144 respectively, were reported for the island by Mills- paugh, but these records seem not to have been accepted in the North American Flora, XXV, Pt. II, 1910, the former species being credited to "Jamaica and the lesser Antilles," the latter to " His- paniola" only. Family POLYGALACE.'E. Key to the Species Enumerated.

From the descriptions and from such specimens as he has seen, the writer must claim inability to distinguish this species from Polygala glochidiata Humboldt, Bonpland, & Kunth, a species reported as widely distributed from Mexico through continental tropical America to Brazil, with a few localities reported in the West Indies. The fully ripened seeds of the plants from the Isle of Pines, are "obovate- elliptic" (Wright) to almost perfectly spherical, the apex apiculate, the surface dark brown and somewhat shining, the hairs being white, erect, and hooked at the tip. The seeds are about 0.7-0.8 mm. in diameter. Flowers are light rose-purple in color. •-* 366. Polygala gracilis Humboldt, Bonpland, & Kunth.

General Distribution: Cuba, the Isle of Pines, Mexico, Costa Rica, Colombia, and Venezuela. These specimens are too near Polygala paniculata Linnaeus, one of the four plants on the sheet being well branched. As now understood the writer considers these two species to be practically synonymous. Family DICHAPETALACE.^. 367. Tapura obovata Britton & W^ilson.

This is a sparsely branched shrub about two to four feet high, growing quite commonly in the sandy pine woods, rocky slopes, or even in swampy woods, in nearly every part of the island visited. 164 Annals of the Carnegie Museum. Some of the flat-topped inflorescences are composed of as many as fifty flowers, several of which are usually in bloom at once and, on account of the bright scarlet color, they make the plant quite striking. The flowers vary somewhat in color, some of them showing a tinge of yellow. Added to the striking character of the flowers, the bright green oblanceolate leaves, towards the lower part of the branches, have an unusual form. They usually swing out at the base into one or two sharply acuminate lobes. 392. Jatropha angustifolia var. glauca (Grisebach) Pax. Jatropha glauca Grisebach, Nachrichten Kgl.

General Distribution: Western Cuba and the Isle of Pines. The flowers and fruit of the two varieties are identical in character, but the shape of the leaves is so strikingly different that were it not for occasional transitional forms one would have good reason for regarding them as distinct species. The plants are low, usually not over two or three feet high, simple or sparsely branched, woody, par- ticularly below, and at the base there is often an enlarged woody stem, just underneath the soil, often an inch or more in diameter. The flowers are not so brilliantly scarlet as are those of Jatropha glaucovirens, the color ranging from a purplish or rose pink to a pure white. In some localities only white ones were seen.

The writer was told that this plant has been found wild upon the island, but no specimens were seen. Dr. J. F. Shafer collected a specimen (root) in 1910, probably cultivated. General Distribution: American tropics, especially South America. The natives of the island still use the plant for food, cooking the large roots, so that there is a chance that it may be given good oppor- tunities to become naturalized, if it has not already done so. 397.

The fruit of this tree is of about the size of a small orange, finally becoming dry and bursting apart with much force. The seeds rattle about in the dry fruit, hence the name "Sand-box Tree." The trees are fairly large, with a spreading crown, so that they are of consider- able value as shade trees, and are so used in some of the West Indian islands. 398.

General Distribution: From the Bahamas and Cuba south through the West Indies and in continental tropical America. Now quite generally naturalized throughout the tropics. See Plate IX. The cashew is a very valuable tree, as yet not sufficiently appre- ciated. The wood is strong, hard, and useful in a variety of ways; the peduncle of the fruit becomes enlarged and pear-shaped, and, when mature, constitutes a subacid, slightly astringent edible fruit, which is either eaten raw or prepared in various ways by cooking; and the nut, which is kidney-shaped and about one inch long, is claimed to be a strong competitor of the almond when properly roasted. The middle layer of the shell of this nut is poisonous, but the poisonous property may be destroyed by heat. Altogether the Jennings: Contribution to Botany of Isle of Pines. 169 various uses of this plant, many of them not here mentioned, give it a very prominent place among the useful trees of the tropics. {See Cook and Collins, "Economic Plants of Porto Rico," Contrib.

Near Nueva Gerona, December 16, 1903, A. H. Curtiss, No. 234. General Distribution: Bahamas, West Indies, and continental tropical America. In the present unsatisfactory condition of the genus Triumfetta, the determination of species is not easy. The specimen from the Isle of Pines is probably correctly placed under Lamarck's species althceoides, but the writer is not entirely satisfied with this disposition. The leaves are distinctly and acuminately three-lobed, in general outline very similar to those of Acer spicatum. The basal teeth are not conspicuously transformed into glands, the calyx is densely tomentose, the sepals and petals are narrow and about 7-8 mm. long, the stamens are about twenty-five in number, and the body of the fruit, as well as the spines, is pubescent. Although Triumfetta althceoides is regarded as quite variable, the writer is of the opinion that the plant from the Isle of Pines will be found eventually to be distinct from that species, and, possibly, more nearly related to some of the numerous South American species. 430.

The bast of this plant furnishes a valuable fiber, used in many places in the tropics for making ropes, and having also other uses, mainly domestic. The fiber becomes stronger after long maceration in water, and, as the plant grows very readily from cuttings or from 182 Annals of the Carnegie Museum. the cut stumps, it is highly probable that, in the future, the plant will be cultivated and appreciated to a much greater extent than is the case at the present time.

This species is a native of the Old World tropics and is rather widely cultivated for the acid, fleshy calyx, which, when cooked, much resembles cranberry sauce. The stems are also used in some countries as a source of fiber, which is strong, silky, and quite highly esteemed especially in the Asiatic tropics, where it is known as the "Roselle Hemp." 453.

Britton notes that the steep slopes of the rough hills and mountains in the northeastern part of the island are "dotted by the large and peculiar green-barked ceibon tree (Bombax emarginata), 184 Annals of the Carnegie Museum. one of the few deciduous-leaved trees of the flora, essentially bare of foliage at the time of our visit." No good specimens are at hand representing this species, it being leafless at the time of our visit also. It is the most conspicuous tree on the upper slopes of the Caballos Mts., at least during the dry- season. See photograph (Plate XII). Towards the top of the mountains the large sprawling limbs of the trees furnish favorite habitats for a considerable number of epiphytic orchids and brome- liads. Family STERCULIACE^.

To the excellent recent description of this peculiar plant, as given by Urban in the Symbolse Antillanae, V, 1908, p. 426, it should be added that the leaves on vigorous non-fruiting branches tend to have a decidedly obtuse or rounded outline at the apex and that the 188 Annals of the Carnegie Museum. base is then often quite strongly cordate, thus presenting quite a contrast to the leaves of the fruiting branches on the same plant. The shrubs, as the writer found them on the Isle of Pines, have a maximum of about seven feet in height. They are rather straggling in habit, and the flowers are a bright yellow or golden-yellow. The leaves are lustrous on the upper surface but dull below. 464. Ouratea cubensis Urban, Gomphia acuminata A.

Shafer. General Distribution: Cuba and the Isle of Pines. Unfortunately the plants were not in such condition when found as to furnish good specimens of flowers or fruit. For this reason it has been thought best to regard the plant provisionally as Hypericum styphelioides, although a comparison of the specimens with a fine sheet of specimens of that species collected by J. A. Shafer (No. 432) at Herradura, Pinar del Rio Province, Cuba, April 30, 1903, leaves considerable doubt as to the identity of the plants from the two islands. The Isle of Pines specimens have larger, thicker, more closely imbri- cated, and more conspicuously 4-ranked leaves, and it is not unlikely that they represent an undescribed species. 470.

Curtiss, No. jSg. General Distribution: Western Cuba and the Isle of Pines. Urban (Synibolce AntillancE, I, 1899, pp. 368-369) has described as Rheedia portoricensis a plant of Porto Rico very closely related to R. aristata, but having the petioles 5-8 mm. long, instead of 2-3 mm., lateral nerves 25-35, instead of 15-20, and pedicels 2-3 cm. long, instead of but 1-1.5 cm. Curtiss's specimen from the Isle of Pines is intermediate in most characters; the petioles often reach 5 mm. in length, the lateral nerves on the larger leaves are between 20 and 25 in number, and the longer pedicels reach a length of over 2 cm. Further study of more extensive collections will probably show good reasons for regarding Rheedia portoricensis as a variety of R. aristata. 472. Clusia rosea Jacquin.

General Distribution: The species has been variously reported from Cuba, Jamaica, and Santo Domingo, but with the more recent description of new species, e. g., Lagetta Wrightiana Krug & Urban, it is likely that this distribution will be decreased in extent. The writer is not prepared, however, to dispute the correctness of the reference of Blain's specimen to Lagetta lintearia. The lace-bark tree is said to be common in some parts of the island. Dr. Britton has this to say of it in the San Juan region: "The Loma Daguilla (Lace-bark Hill), an isolated mountain about 600 feet high, situated about two miles west-southwest of the San Juan Hills, is of exceptional interest. It takes its name from the lace-bark tree (La Daguilla), a near relative of the Jamaica lace-bark, here rather abundant; its inner bark is separable into a beautiful netted fiber." Family LYTHRACE^.

In recent years the lines of demarcation between the West Indian species of Calyptranthes have been drawn very closely — it seems to the writer too closely in some cases — so that ordinary variations are in many cases very difficult to place in the species, as they are now described. The two specimens catalogued above perhaps represent the same species, the Bibijagua specimen having slightly narrower leaves and more nearly glabrous twigs. 512. Calyptranthes punctata Grisebach.

A slender tree about fifteen feet high, with pink flowers. Tamonea tomentosa, ranging from Trinidad to Guiana and Brazil, apparently varies considerably in the shape of the base of the leaf, but it is possible that the plant here described as a variety may prove to be a distinct species. The brown-tomentose character of the axis and branches of the inflorescence and of the under side of the leaves makes it a striking plant. The upper surface of the leaves is only slightly stellate-pubescent and turns blackish in drying. The leaves are 9-nerved, the outermost nerve being rather indistinct and bordering closely the bases of the low closely approximate crenations, the innermost nerve being placed about half-way between the mid- nerve and the margin. The inflorescence is compact, in our specimen being 6 cm. in diameter by 19 cm. long. Calyx-tube about 10-12 mm. long, the lower third about 4 mm. in diameter, cjdindric, the upper third abruptly enlarging into a campanulate portion with widely rounded lobes only about i mm. high, and tuberculate on Jennings: Contribution to Botany of Isle of Pines. 209 the back of the tip. Petals about 8-10 mm. long, narrowed below^ into a claw, the upper portion obliquely ovate, about 5 mm. wide, oblique and retuse at apex, finely stellate tomentose on the outside, glabrous and pinkish inside.

Type. — Along arroyo bank near Los Indios, May 19, 1910, 0. E. Jennings, No. 426. Herbarium, Carnegie Museum. Other specimens ■of the same species were collected as follows: Swampy margin of pond one mile east of Nueva Gerona, May 6, 1910, 0. E. Jennings, No. 5(5, and a small tree along an arroyo near Sante Fe, May 25, 1910, O. E. Jennings, No. 553. Flowers white. This species is a small tree or perhaps more commonly a tall shrub growing in the marginal thicket of ponds, or along the banks of arroyos, and is closely related to Pachyanthus ovatus Cogniaux and P. cordifolius Cogniaux, and there is a possibility that with more complete collections available for study these three species will be best treated as one, under the name of Pachyanthus ovatus Cogniaux. The present status of the group would not, however, justify such a decision. The specimen {No. JJ4, Jennings) collected in the xero- phytic sandy pine-barren at Los Indios fits the description of Cog- niaux's ovatus very closely, thus indicating a possible ecological relationship between that species and longijolius.

Jennings, No. 324 (Type); same date and locality, No. 625. General Distribution: Known only from the type-locality. The plants grew scattered about in the pine-barrens, the growth always open and scraggly, the branches few and more or less erect, the leaves small and closely bunched towards the ends of the branches. The flowers occur densely bunched at the apex of the branches, the corolla being light pink and up to 20 mm. broad, glandular-pubescent, as is also practically the whole upper part of the plant. The lance- olate, acute sepals are about 4 mm. long, copiously soft-ciliate with gland-tipped and naked hairs, the peduncles and calyx more or less deeply reddish-purple in color. The filaments are pubescent near the base, this not being a good distinguishing character between K. aggregata and the closely related Kalmiella ericoides of western Cuba (Small, /. c, in the key to species of Kalmiella, noting for K. aggregata: "Filaments glabrous"). 537.

Type. — Scrubby woods southwest of Bibijagua, May 7, 1910, 0. E. Jennings, No. 86. Specimen in the herbarium of the Carnegie Museum. Of the same species is also No. 264, A. H. Curtiss, "West Indian Plants." Near Nueva Gerona, January i, 1904. The latter specimen was distributed as Mesosphcerum rugosum (Linnaeus) Pollard. Mesosphcerum Hollandianiim is most closely related to M. rugosum (Linnaeus) Pollard {Hyptis radiata Willdenow), a rather common plant of wet places and swamps from North Carolina to Florida and Texas and by various authors identified and reported for localities southward in continental tropical America as far as Colombia. M. Hollandianum differs, however, from the continental species in the very much narrower and blunter and more remotely crenate leaves, the plant much more nearly glabrous, and the bracts and calyx-lobes practically glabrous, but decidedly, although minutely, ciliate. M. angustifolium is to be regarded probably as having been derived by isolation from M. rugosum. This species has been named in honor of Dr. W. J. Holland, the Director of the Carnegie Museum, to whom much credit is due for his support and encouragement of the studies of the natural history oi the Isle of Pines. Hyptis (1786) has been adopted by the International Congress in place of Mesosphcerum (1756), contrary to the principle of priority, hence the name of the species described above would be, according to the International Rules of Botanical Nomenclature, Hyptis Hollandi- ana. 246 Annals of the Carnegie Museum. 624.

Type. — Near Nueva Gerona, Isla de Pinos, W. I., January 19, 1904, A. H. Curfiss, "West Indian Plants," N'o. 301. Specimen in the herbarium of the Carnegie Museum. This species belongs to the section Cyrta Bentham (under Hyptis) and is most closely related to the Brazilian species MesosphcBrum clavelliferum (Bentham) O. Kuntze and M. microphyllum (Pohl) O. Kuntze. The fruiting heads of M. clavelliferum, however, are stated as being 1.5 cm. or more in diameter, nearly three times the dimension of the Isle of Pines plant. The leaves of M. microphyllum differ from the plant from the Isle of Pines in that they are hardly 7 or 8 mm. long, and there is a further difference in that the peduncles of the former species are two or three times as long as the heads. The writer has had access to but few specimens from this large and difficult genus, but a careful comparison of the various descriptions available would leave little doubt of the specific distinctness of the plant from the Isle of Pines. To those botanists who abide by the Nomina Conservanda of the International Rules of Botanical Nomenclature this plant should be known as Hyptis capitellata. 248 Annals of the Carnegie Museum, 627.

Type. — Growing in the white sand of the pine-barrens at Los Indios, May 21, 1910, No. 456, 0. E. Jennings. Specimen in the Herbarium of the Carnegie Museum. The type consists of but two specimens, collected in flower, and, unfortunately, none of the capsules were mature. The plants were growing near the stations for Stenandrium droseroides, but they differ from that species markedly in the much larger flowers of a totally different color. The two species are quite similar in general ap- pearance. Family BIGNONIACE^. Key to the Species Enumerated. Leaves simple. Leaves practically or entirely smooth above.

Jennings, No. j^i; abundant but growing singly in the pine-barrens north of Los Indios near the Majagua River, May 19, 1910, 0. E. Jennings, No. jpQ. General Distribution: Cuba and the Isle of Pines. A low rosette plant with a short erect subterranean rhizome and roots bearing fusiform tuberous thickenings, and growing rather commonly on the sandy soil of the pine-barrens at Los Indios. The flowers are white with a minute crimson eye. The corolla is some- what two-lipped, the two narrower upper lobes being connate to about one-half their length. Considering the variation of the specimens in size, number of flowers, length of floral bracts, leaves, hairs, etc., as well as the fact that the specimens have tuberous roots, it appears doubtful if consistent differences can be established between the three species Stenandrium tuberosum (Linnaeus) Urban {S. riipestre Nees), S. acuminatum Urban, and S. droseroides Nees. If these plants should prove to be synonymous the species would bear the name Stenandrium tuberosum (Linnaeus) Urban, = Gerardia tuberosa Linnaeus.

General Distribution: Quite generally distributed in the West Indies and in tropical South America. The species is a forest tree reaching a height of fifty feet or more. It is frequently cultivated for the sake of the fruit, which often reaches a length of four or five inches and is much used in some places in mak- ing a refreshing drink. The fruit is sometimes eaten but is not very highly esteemed, being said to contain a large amount of tannic acid. 678. Amaioua fagifolia Desfontaines.
