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

Of the seven parts composing volume 18 of the Contributions, tho first is by Mr. W. E. Safford, of the Bureau of Plant Industry, United States Department of Agriculture. It represents an extension of his work on the family Annonaceae. In various preliminary papers Mr. Safford has proposed several new sections of the genus Annona and has described many of the tropical American species. The present treatment is more comprehensive, embracing a synoptical view of the genus by natural groups and sections, with descriptions of additional new or inadequately known species. There are given, also, descriptions of two closely allied new genera, Fusaea and Gean- themum, and critical notes upon Rollinia, Duguetia, and Raimondia. This last genus, recently founded upon a single species, is found prop- erly to include also a Colombian plant, described long ago by Hum- boldt, Bonpland, and Kunth as Anona quinduensis. The second paper, by Mr. Henry Pittier, also of the Bureau of Plant Industry, United States Department of Agriculture, is in continua- tion of a series begun by him several years ago in the Contributions, dealing principally with Colombian and Central American plants which are of economic value. Besides descriptions of two new species of Brosimum and Spondias there are included further notes upon the difficult genus Sapium and a discussion of the nomenclature of the sapote and sapodilla, two important tropical American fruit trees whose taxonomic history is exceedingly involved. The third part consists of a second installment of studies by Mr. Paul C. Standley, of the United States National Herbarium, upon the flowering plants of tropical America. The new species described and the changes of nomenclature proposed are largely the result of work upon certain groups, chiefly Rubiaceae, Malvaceae, and Legu- minosae, as represented in the extensive collections obtained recently in Panama during the progress of the Smithsonian Biological Survey of the Panama Canal Zone. A large part of the paper consists of descriptions and nomenclatorial changes in the Amaranthaceae and Allioniaceae incidental to monographic work upon these families. Two new genera are proposed in the Malvaceae. Part 4 is the fifth paper of Mr. Pittier’s series mentioned above. In this part are discussed various trees and shrubs of Central America v VI PREFACE, and the northern part of South America, hitherto imperfectly or not at all known. Most of them are components of the wonder- fully rich native Isthmian silva and several aro of importance as timber trees. \V the common A. reticulata by the na- i\ (\ tives of Alta Verapaz, who call it A “anona amarilla.” In general appear- ance the fruit resembles very closely the common alligator apple of trop- ical mangrove swamps (A.glabra L.). \ but the latter may easily be distin- \ guished by its large flowers with 6 |/\ \ ovate valvate petals, its laurel-like leaves, its edible fruit, and its yellow RQ or tan-colored seeds.

On account of the broad connective and the perfectly formed inner petals, the writer provisionally assigns A. palmeri to the section Atta, which includes A. sguamosa and its allies. It has, however, the habit of certain species of Rollinia, and its short, round-pointed, thick petals, together with its Rollinia-like seeds may indicate that it is a link between the genera Annona and Rollinia.

LocaL NAMES: Chirimoya de la barranca (Guadalajara, Jalisco) ; Chirimoya cimarrona (Tequila, Jalisco). Annona longifiora is very closely allied to A. cherimola Mill, but is easily distinguished from that species by its longer flowers with shorter pe- duncles and loose floccose hairs about the base of the corolla (fig. 56), by its leaves, which are at length glabrate instead of persistently pubescent be- tween the lateral nerves, and by its peculiar seeds, which resemble large pine nuts rather than the seeds of an Annona. It was originally described as a shrub 8 feet high; but specimens collected from the type locality by Mr. Cc. G. Pringle grew to the height of 10 feet. About the base of the young branchlets, where they issue from the bud, is a collar of soft plushlike pu- bescence. As in many other species of the Annonaceae, the lowermost leaves of the flowering branchlets are smaller than the succeeding ones, in this spe- cies often suborbicular; the peduncles are extra-axillary, usually issuing from near the base of a branchlet and often opposite a small suborbicular leaf.

The minute inner petals scarcely exceed the stamens in length and might easily escape observation. In the type collection the fruits were immature. They were of two distinct forms analogous to the umbonate and smooth forms of Annona cherimola and of A. diversifolia. That in the Gray Herbarium is globose-ovate and “ covered with flat reticulations,” as described by Doctor Watson. In the National Herba- rium, however, the fruit of the type collection is conoid and bears numerous SAFFORD—CLASSIFICATION OF ANNONA, 47 umbonate protuberances, as shown in figure 55. Mature seeds collected by Pringle in the Barranea of Guadalajara in 1902 are very different from those of Annona cherimola, being truncate or obpyramidal in form without a caruncle at the base, and having the testa quite smooth and nutlike, thicker than those of the common edible custard apples and similar in texture to the seeds of Annona diversifolia. They differ so much from those of all other species of Annona that they alone would be sufficient to identify this species. According to Doctor Palmer’s notes, the fruit is edible either raw or cooked. A sweetmeat is made by boiling it with sugar, together with the fruit of the tejocote (Crataegus mexicana).

Smith is very closely allied to A. diversifolia Safford,’ the “ilama” of Colima and Acapulco (figs. 27, 28, pp. 19, 20) ; but it differs in its shorter-petioled, smaller leaves, its oblong flowers and thicker peduncles, and its persistently ciliate, smaller bracts or prophylla. Mr. O. F. Cook, of the Bureau of Plant Industry, U. S. Department of Agri- culture, while on a mission of agricultural exploration, found this species near Tapachula, in the State of Chiapas, southern Mexico, in 1902, 7 years before the type specimen described by Capt. Donnell Smith was collected, and describes it in his field notes as follows: “May 8, 1902. There is an Anona with glaucous leaves not infrequent at Tapachula, State of Chiapas. The smaller leaves or bracts are, like the bud scales, clothed on the back with long, silky, brown hairs. The mature petals are greenish at the base and become yellow in the distal half; along the margins and on the inside they are tinged and mottled with pink and deep red like the flesh of a peach. The clustered apices [con- nective heads] of the stamens are dull pinkish when fresh. The pollen lies in the anthers in chains [of tetrads], two chains in each of the two sacs. The stigmas have a joint or collar at the base and are bathed in a transparent fluid [at the time of polli- nation]. The petals turn dark brown within a few minutes after being placed in alcohol.” EXPLANATION OF PLATE 26.—Photograph taken in the field, at Tapachula, State of Chiapas, Mexico, near the Guatemala boundary, May 7, 1902, by Mr, Guy N.

These were nearly all detached from the branches, from which the leaves had also sepa- rated, as seen in the specimens in the De Candolle Herbarium as cited. The leaves agree in shape and texture with the specimens collected by Wright in the Province of Matanzas, here figured, except that several of the latter are more distinctly mucronulate than any of the leaves of the type. The normally shaped ones, growing on the upper portions of the branches, shown in figure 30 (p. 20), are distinctly oblong, and not suborbicular as in the closely allied A. crassivenia of Almacigos (fig. 31, p. 20), which has hitherto been confused with this species. From the camera lucida drawings of the essential parts (fig. 58) it will be seen that the mature stamens of Annona bullata are broader, thinner, and flatter, the hairy carpels more slender, and the (ovoid) terminal 50 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. styles more pointed than Richard’s figures of the corresponding organs would indicate, while plate 27 shows that the flowers are not subterminal as originally described, but issue normally from the base of the branchlets, and that the mature petals are almost flat and rounded at the apex, instead of subtriquetrous and subacute. The indument of the peduncle and calyx is ferrugineous or deep cinnamon color, while that of the outer petals is composed of much finer hairs and is pale rufous or fulvous. Richard is quite right in recognizing the relation of this species to Annona cherimola, but, for the reasons assigned in describing the section Saxigena, it seems advisable to place this and A. crassivenia in a special section. This species, on account of the aromatic properties of the wood, is called “laurel.” The leaves are eaten by horses and cattle and the fruit by pigs. The latter is described as hard and sour and unfit for the table. The pubescence of its surface is fulvous rather than ferrugineous. Its seeds are remarkable for the bright golden, smooth, waxlike surface of their thin testa. They are in- closed when fresh by a thin membranous aril and are surrounded by scant pulp.

Annona cascarilloides owes its specific name to ‘the resemblance of the vena- tion of its leaves (fig. 61) to that of the leaves of certain species of the genus Cascarilla. The flowers were said in the original description to resemble those of the genus Rollinia, but this statement is quite misleading (see fig. 60). They appear to be intermediate in form between the flowers of Annona cherimola and those of A. globifiora. In their swollen base and slender apex they are not unlike the flowers of A. acutiflora Mart. of Brazil, but the latter have conspicuous inner petals, and these are quite lacking in the specimens of A, cascarilloides examined. The fruit, which is about as large as a plum, is devoid of protuberances or stigmatic scars.

DISTRIBUTION: Known only from the type locality. SPECIMENS EXAMINED: CuBa: Type material as cited. This species was found growing in the form of a much branching shrub, about 8 feet high, at an elevation of about 680 to 1,000 meters above sea level in thin soil. The aromatic, brittle leaves have very much the flavor of nutmeg and bear a resemblance to those of Annona cascarilloides of western Cuba. However, they are covered beneath with persistent fulvous feltlike tomentulum and are devoid of the bright-ferrugineous hairs which occur on the midrib and lower surface in the latter species, while the lateral nerves are peculiar and differ from those of all other known species of the genus in curving backward or downward toward the petiole, as shown in figure 33.

In the type specimens, as described by Schlechtendal, more or less imperfect minute inner petals were present, but in the specimens examined by the present writer no inner petals were observed. It is quite probable, however, that they are sometimes present, as in Annona rosei. Annona globiflora was first collected the latter part of the 18th century near the village of Espinal, in the State of Vera- cruz, by Mocifio, and it was described under the name Annona fruticosa in Mocifio & Sesse’s Flora Mexicana. This work, however, remained in manuscript for nearly a century, and the description was not published until 1894, as above cited. The name Annona globiflora, very appropriately applied to it by Schlechtendal in 18386, must therefore take precedence.

(PLATE 34. Ficures 64, 65.) Type in the herbarium of the Royal Botanical Museum, Berlin (without fruit) collected near Barahona, south coast of Santo Domingo, near the Haitian frontier, in April, 1911, by Rev. Miguel Fuertes (no. 258). DISTRIBUTION: Santo Domingo. SPECIMENS EXAMINED: Santo Dominco: Duplicate of type; same locality and collector, fruits, September, 1912 (both U. 8. Nat. Herb.). LocaAL NAME: Guanabanita (Barahona, Santo Domingo). The closest ally of Annona bicolor is Annona globiflora Schlecht. of eastern Mexico. From this species it differs in its thicker, broader, coriaceous leaves, its smoother black-seeded fruits, and its pointed flower buds. A specimen of the type collection in the United States National Herbarium bearing the label “Anona avillifiora Spr.?” was recognized as a new species by the writer, who communicated the fact to Professor Urban, asking that Father Fuertes be re- quested to secure fruit from the type specimen, in order that the description of the species might be completed. Professor Urban replied that he had already “published the new Anona of Santo Domingo as A. bicolor in Symb. Antill. VIL. (June, 1912), p. 223.—Fuertes no. 258,” and added that he had not seen fruits. Fruits of the type plant were afterwards received by the writer directly from Padre Fuertes, who described them as of a green color on the exterior when fresh and cream color in the interior. “The fruit,” he added, “smells like some of the other Anonaceae and keeps the characteristic odor of the family. The leaves and wood are fragrant, and I do not doubt but that they would yield a good [aromatic] extract.” The species was previously collected in 1819 to 1820 by Carlos Bertero on the island of Hispaniola, and was referred by Sprengel to Annona awilli- flora DC., but the latter is a Guiana plant with much longer peduncles, as Professor Urban has already pointed out. From figure 64, showing a flower bud with one petal removed, and figure 65, showing a stamen and carpel, it will be seen at a glance that the present species is closely allied to the Mexican A. globifilora Schlecht., the type of the section Annonella. The recent discovery by Dr. J. N. Rose of another species of this section on the island of Santo Domingo, not very far from the type locality of A. UVicolor is interesting.

Growing in dry, rocky situations, associated with Cactaceae and other xerophi- lous plants. DISTRIBUTION: Known only from the type locality. According to Doctor Rose’s field notes, Annona rosei is a bush or small tree from 6 to 20 feet in height. It was found mostly on the banks of a stream and adjacent low hills, in association with Agaves, Opuntias, and Acacias, the exact type locality being about 3 miles above the town of Azua along the little stream which is the source of its water supply. Azua is located in a great cactus desert on the leeward or southern side of the island and is probably one of the driest parts of Santo Domingo, the annual rainfall of the region being about 8 inches. Doctor Rose spent about ten days at Azua, collecting in all directions and looking out especially for Annonaceae, but the present species was seen only on this one occasion; not many individuals were observed, and these were in- cluded within the radius of a mile. Fortunately it was in bloom, and Doctor Rose collected fully developed flowers which were preserved in formalin. Though normally having three fleshy thick outer petals and three small scale- like inner ones, both the dry herbarium material and the flowers in formalin 58 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, include specimens in which one of the inner petals is abnormally enlarged and is wedged between two of the outer petals, as shown in plate 36.

Among the plants originally described under the generic name Annona several were found to differ so radically from the type of that genus that it became necessary to place them in distinct genera. Among the related genera are Rollinia and Duguetia, established in 1825 by Augustin de St. Hilaire, and Raimondia, recently estab- lished by the present author. ROLLINIA St. Hil. Rollinia was named in honor of the French historian Charles Rollin. Its type is Rollinia longifolia St. Hil. discovered by St. Hilaire on the Lagoa de Fretas, near Rio de Janeiro (pl. 38). The plants included in this genus do not differ trom those of Annona in their essential parts nor in their fruits, but they have a peculiar gamopetalous corolla, the parts of which corresponding to the outer petals of the Annonas are developed into three obtuse wings or spurs, which leave only a very small-opening above the essential parts. This genus includes the following species, originally referred to Annona. Rollinia mucosa (Jacq.) Baill. Anona mucosa Jacq. Obs. Bot, 16. 1764, excel. syn, Rumph. Anona obtusiflora De Tussac, Fl.

Rollinia mucosa is a species with large edible fruit, but this not equal in flavor to that of the chirimoya or sugar apple. It was first described by Jacquin from specimens of plants growing wild and sometimes cultivated on the Island of Martinique; and afterwards, under the name of Anona obtusiflora, by Tussae from a specimen growing in an orchard at the western extremity of the Island of Hayti. It is possible that more than one species is included by authors under this specific name and that wild plants with smaller flowers and inedible fruit have been erroneously referred to the species. The accompany- ing figure shows that the lobes of the corolla are widely diverging but with an upward curve. Other closely related species in Central America, with geminate instead of solitary flowers, decurved corolla lobes, and small fruit with seeds very much smaller than those of A. mucosa have been referred to the latter EXPLANATION OF PLATES 38, 39.—PI. 38, type specimen, Reproduced from St. Hilaire.

It is fortunate that the type lo- ealities of the plants described under the names Anona mucosa, A. obtusifiora, and Rollinia sieberi, all of them West Indian, are definitely known, so that specimens from the same localities can be carefully compared. It must be borne in mind that the fruits of Rollinia are even more important than the flowers and leaves in the identification of species, as in the case of Anona reticulata and A. squamosa, species which can be distinguished from each other only with diffi- culty without specimens of the fruit. Very closely related to Rollinia mucosa are R. orthopetala A. DC., from British Guiana, and R. pulchrinervia A. DC., from French Guiana, Delicious fruits grown at Miami, Florida, from seed received from Paré, Brazil, have been transmitted to Mr. David Fairchild, of the Bureau of Plant Industry, at Washington, under the name R. orthopetala. But the flowers of R. orthopetala (which have never been figured) are described as having their corolla lobes erect and incurved, while those of the Miami plants have their lobes widely di- verging and decurved toward the peduncle, agreeing in this respect with the description of the flowers of R. pul- chrinervia, which is said in the original description to be very closely allied to R. orthopetala, as both of them are also said to be to R. sieberi of Trinidad.

Fur- ther, the indument of the lower surface of the leaves, petioles, and peduncles in this genus is scurfy and stellate-pilose, while in Annona the hairs are simple or sometimes fascicled in clusters of 2 to 6. It proved afterwards that Anona fur- furacea St. Hil. (figs. 69, 70), described and figured in the same work in which it was published, had to be included in the genus Duguetia. Many species have since been added to this genus, all of which appear to have the new parts clothed with stellate pubescence or tomentum. Duguetia was regarded by Baillon as a synonym of Aublet’s Aberemoa, and Robert E. Fries transferred all the species of Duguetia known to him to this 4 ‘2 "Fl. Bras. Merid. 1: 35. pl. 7. 1825. SAFFORD—CLASSIFICATION OF ANNONA, ; 61 genus;’* but Aublet’s figure of Aberemoa guianensis (fig. 71), on which the genus was based, represents the carpels as pediceled and ovate, very much like those of certain species of Guatteria, while the leaf, as figured by Aublet, does not appear to be that of a true Duguetia. The type locality of Aberemoa guianensis (“ Habitat in sylvis remotis sinemarien- sibus”) is not indicated with precision. Flowers were lacking in the type ma- terial and there is no specimen identified with certainty as Aberemoa guianensis in any herbarium, nor has its flower ever been described. An imperfect specimen in the herbarium of the Museum of Paris of a plant collected by Perrotet and Poiteau was regarded as a variety gla- brescens of Aublet’s species by Sagot, who calls attention to the fact that Aublet’s type, with tomentose branchlets and slightly tomentose leaves, is absent from the herbaria of Paris, and characterizes it as “rara et pulcherrima planta nondum bene nota, insignis foliis maximis, fructu Fic. 69.—Flower of Duguetia furfuracea.

Its type species is Raimondia mon- oica Safford* from the Cor- dillera Central of Colombia. The fruit in this genus is a solid fleshy syncarpium very much as in Annona, but the flowers are monece- cious and the stamens dif- fer radically from those of both Annona and Rollinia in being devoid of the char- acteristic terminal swollen heads above the pollen sacs at the tips of the con- nectives. To this genus must now be transferred the following species: 1Vet. Akad. Handl. Stockholm 34°:19. 1900. ? Ann. Sci. Nat. Bot. VI. 2:1386. 1880. *Contr. U. S. Nat.

FUSAEA AND GEANTHEMUM, NEW GENERA. One noteworthy plant which has been placed under Duguetia must undoubtedly be removed from that genus. It was originally described (1775) by Aublet under the name Annona longifolia; but Baillon, notwithstanding the fact that the carpels become solidified into a fleshy syncarpium instead of remaining discrete, as in Dugue- tia, that the hairs of the indument clothing its new growth are simple instead of stellate, and that the stamens are radically different from those of the latter genus, placed this plant in the genus Duguetia, under the name D. longifolia, setting it apart, however, from the rest of the genus under the sectional name Fusaea. That it is not congeneric with the plants of the genus Duguetia is so evident that the present writer does not hesitate to raise Baillon’s section to the dignity of a genus, which must also include Annona rhombipetala Ruiz & Pav. Another plant which must receive generic distinction is Anona rhizantha Eichl2 This species, though resembling Duguetia in its stellate-hairy and scurfy indument and in the discrete carpels of its fruit, differs radically from it as well as from Annona in its peculiar stamens, which closely resemble those of the genus Raimondia, in being devoid of an expanded head or swelling at the tip of the con- nective above the pollen sacs. From Raimondia it is separated by the character of its fruit as well as by its indument and the much greater development of the inner petals of its corolla. This plant was placed in the genus Aberemoa (Duguetia) by Robert E. F ries, who set it apart from the rest of the genus under the sectional name Geanthemum. From the peculiarities above noted, however, it is evident that it cannot be included in the genus and the present writer feels compelled to raise Fries’s section to generic dignity. FUSAEA (Baill.)

Type species, Fusaea longifolia (Aubl.) Safford. The distinctive characters of the type of this genus were first noted by Baillon, who pointed out that its fruit (fig. 74), instead of being composed (as in Duguetia of distinct woody ecarpels, inserted in cavities in the hardened torus, is a solid mass, “une véritable boule de bois, sans asperités de la surface rappelant la presence de ses nombreux carpelles;” and that the outer stamens are modified into “lamelles pétaloides, imbriquées, longuement obovées;”* and Robert BH. Fries, who followed Baillon in regard- ing Fusaea as the section of a genus (Aberemoa), says that “this section departs in so many respects from the j.,, 72__mower of Fueaea longifolia.

Paraense 5: 356. 1908. Type collected in the moist primeval forests between the rivers Cumand- mirim and Ariramba, December 18, 1906, by A. Ducke (no. 7995). Closely allied to these two species and probably congeneric with them is a plant described and figured by Velloso under the name of Uvaria sessilis* (fig. 75), which Martius erroneously regarded as a synonym of his Duguetia bracteosa. If the two species were identical, the specific name of Velloso would take precedence. As seen in Velloso’s figure, however, both the leaves and flowers of his plant bear a close resemblance to those of Geanthemum rhizanthum and apparently represent a closely allied form. The fruit of Duguetia bracteosa has never been figured, but it is described by Martius as equal in size to the nut of Juglans regia, globose, with about 30 to 40 pentagonal obovate carpels, mucro- nate with the persistent style, and of a scarlet to brownish color. The type locality of D. bracteosa is the primeval forests of the Province of Bahia, near St. George of the Islands. The flowering branch of a plant in the Museum of St. Petersburg identified as Duguetia bracteosa, collected by Riedel at Castel- novo, Province of Bahia (no, 493), and figured by Robert E. Fries,’ shows the inflorescence bearing large, persistent, sessile, ovate bracts which are absent from Velloso’s figure of Uvaria sessilis. Martius was then, in all probability, mistaken in regarding the latter species as identical with the former, the fruit of which is described as being subtended by a persistent involucre. ADDENDUM.

Under the name Annona jamaicensis at least two species have been included, growing wild in the mountains of Jamaica. Annona jamaicensis, based upon Annona sericea Griseb. (not Dunal), was described by Sprague from specimens collected (1) by William Purdie, in 1844, near Bath, at the eastern extremity of the island; (2) by William Thomas March, who lived at Spanish Town (nos. 4, 7, 1571, without definite locality, collected in 1849-50); (3) by Alex- ander Prior, who collected in the Blue Mountains, in the eastern portion of Jamaica, and in the vicinity of Moneague, near the central part of the island north of the dividing ridge (locality not cited). Of these specimens it is probably Prior’s which Grisebach referred to Annona sericea, since duplicates of Prior’s collections were in Grisebach’s Herbarium. This is the plant fig- ured by the writer in volume 16 of the Contributions, plate 98, with subglobose flower bud. 1 Fl. Flum. 238. 1825. Atlas 5: pl. 125. 1827, ? Arkiv Bot. 54: pl. 1. f. 6, 1905, 68 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. A second species, with obpyriform or pyramidal, acuminate flower buds and long, narrow petals, figured by the writer under the name Annona jamaicensis, as cited in the above synonymy, has recently been described by Fawcett and Rendle as Annona praetermissa. The specimen from which the figure was drawn was received by the writer from its collector, Mr. William Harris, who found it growing on Sheldon Road, St. Andrew, at an altitude of 750 meters, September 10, 1897 (no. 6861). It was distributed under the name of “A. jamaicensis Sprague.” Its single flower differed greatly from that of A. jamaicensis as described by Sprague and as observed on Prior’s specimen in the Gray Herbarium. This led the writer to ask for further material, in a letter to Mr. Harris, dated November 29, 1912, in which he made the follow- ing notes and queries: Annona jamaicensis, as described by Sprague (A. sericea Griseb. non Dun.), has ovate petals 11 to 12 mm. long and 8 mm. broad, while in the specimen collected by you the flower has quite a different shape, with linear-oblong petals 23 mm. long and 6 mm. broad. The fruit of your specimen and also the seeds are larger than those described by Sprague. * * * The cotype of A. jamaicensis in the Gray Herbarium has a single globose flower, like that shown in the accompanying figure. Can it be that specimens seen by Sprague had only immature flowers; or is it possible that there are two similar wild Annonas growing in the mountains of Jamaica, one with globose buds and broadly ovate petals, the other with elongate buds like those of A. reticulata and linear-oblong, or broadly linear petals? * * * Mr. Harris had at this time no further material available; but on October 18, 1913, he sent a number of fine specimens with abundance of flowers, both imma- ture and mature (collected June 25, 1913, near Petersfield, St. Andrew, no. 11,648). This new material showed by the acuminate, pyramidal or obpyri- form buds that it represented a species distinct from Annona jamaicensis, but it was too late to make any changes in the writer’s paper on “Annona sericea and its allies.’ The writer then sent a photograph of Alexander Prior’s speci- men of A. jamaicensis to Mr. Harris,’ and once more called his attention to the marked difference between it and the specimens collected by Mr. Harris. In a letter dated December 19, 1913, Mr. Harris acknowledged the receipt of the photograph and conceded it to be quite possible that the specimen represents another species. Annona praetermissa may be properly called the ‘wild chirimoya of Jamaica.” It must not only be separated from A. jamaicensis, but it must take its place with A. cherimola Mill., A. longiflora S. Wats., and their allies in the section Atta. It is described as having 3-petaled flowers, but like A. cherimola it has in addition to the three outer elongated petals three minute inner petals, ovate in shape, not exceeding half the length of a stamen, and clothed with tomen- tum. These are so small that they can be seen only with the aid of a lens; so that it is not strange that, like those of the chirimoya (first described as Annona tripetala), they should have escaped observation. The close affinity of this species with A. cherimola Mill. is shown by its flowers, fruit, and leaves. As in the latter species, the flowers never open widely. They are solitary or geminate and are extra-axillary or leaf-opposed. The fruit is distinctly areo- late, resembling that variety of chirimoya in which the areoles are concave; and each areole bears a mammiform tubercle slightly incurved or hooked at the tip. The leaves, persistently pubescent beneath, are often relatively narrower than those of a typical chirimoya leaf, and are chiefly to be distinguished by the reddish brown midrib and lateral nerves which are conspicuously con- trasted with the dull greenish color of the remainder of the lower surface. 1 See loc. cit. pl. 98, Contr.

PREFACKE. The present paper, by Mr. Henry Pittier, of the Bureau of Plant Industry, United States Department of Agriculture, is in continua- tion of a series begun by him several yea‘rs ago in the Contributions, - dealing principally with Colombian anc. Central American plants which are of economic value. Besides descriptions of two new species of Brosimum and Spondias there are here included further notes upon the difficult genus Sapium and a discussion of the nomenclature of the sapote and sapodilla, two important topical American fruit trees whose taxonomic history is exceedingly involved.

The present paper, relating mainly to economically important trees of the families Euphorbiaceae and Sapotaceae, is in continuation of several others which have appeared in the Contributions from the United States National Herbarium ! and is similar in scope. MORACEAE. A NEW SPECIES OF BROSIMUM FROM COSTA RICA. Brosimum terrabanum Pittier, sp. nov. Fiaure 76. A large, lactiferous forest tree. Bark smooth, grayish. Crown elongate. Leavesrather large, chartaceous, glabrous, petiolate. Petiolesrather thick, shallow- canaliculate, 8 to 12 mm. long. Leaf blades elliptic, slightly rounded at the base, long and acutely acuminate, 10 to 18 cm. long, 4 to 7 cm. broad. Costa prominent beneath; primary nerves parallel, forming with the costa a very open angle (about 80°). Margin entire. Stipules narrowly lanceolate, acute, about 1 cm. long, smooth, caducous. Receptacles axillary, globose, about 9 mm. in diameter, pedunculate. Peduncles 10 to 14 mm. long, slender, smooth. Bracts of the recep- tacle surface orbiculate, peltate, pedicellate, hairy-ciliate, not over 0.6 mm. in diameter; pedicels hairy, 0.8 to 1 mm. long. Bractlets at the base of the stamens broad and very short (about 0.7 mm.), hairy and ciliate. Stamen 1 to 2.5 mm. long; filament sparsely pubescent; anther l-celled, peltate. Style about 5 mm. long, bifurcate Fie. 76.—Flowers of Brosi- at the middle, dark purple, densely hairy-pubescent. mum terrabanum. a, Male Fruit not known. flower; 6, female flower. . . . a, Scale 6; b, scale 3. Type in the U. S. National Herbarium, no. 577522, col- lected in forests of Pefias Blancas del General, Diquis Valley, Costa Rica, at about 600 meters above sea level, February 9, 1898, flowers, by H. Pittier (Inst. Fis. Geogr. Costa Rica, no. 12029). The type specimen includes a few detached receptacles, gathered on the ground, and two or three branchlets which may have been culled from the baseof the trunk. A few notes taken at the same time give some supplemental information. These materials are certainly not a very satisfactory foundation for a new species, but the leaves differ greatly from those of Brosimum costaricanum Liebm. in having longer petioles, a large blade, and primary nerves almost perpendicular to the costa, and in being thin and G 112:171-181. pls. 18, 19. figs. 11-19.

The receptacles also are larger, with much longer peduncles, and they all seem to be distinctly monoclinous, with well developed and fertile ovaries. On the other hand, they bear a somewhat close resemblance to John Donnell Smith’s no. 2603, collected in Guatemala and distributed as B. alicastrum Swartz. EUPHORBIACEAE.

A tree 20 to 30 meters high, with ascending, slightly divaricate limbs, and a rounded crown. Floriferous branchlets thick. Leaves bunched at the ends of the branchlets and rather large; petiole 2.5 to 4cm. long (1 to 5 cm., Hemsley), thick, hardly sulcate, provided above with two short, rounded glands. Leaf blades oblong or ovate-elliptic, 8 to 16 cm. long (12 to 20 cm., Hemsley), 3 to 5 cm. broad, more or less rounded or cuneate at base, obtuse at tip and provided with a slightly inflexed, cucullate-glandulose acumen; margin glandulose- denticulate; costa impressed above, prominent beneath; primary veins over 20, slender, sinuate, and anastomosed. Stipules suboval, 3 to 4 mm. long and broad, with a broadly scarious, more or less fimbriate margin. Floral spikes 14 to 15 cm. long, inserted in the axils of the upper leaves.

National Herbarium, nos. 530906-7. The foregoing descrip- tion is mainly based on these Tocoté specimens). In December, 1905, after several unsuccessful attempts to find in the forests and on the farms of the Cauca Valley this important rubber tree, which is one of the prin- cipal sources of the virgin or white rubber of Colombia, the writer was directed to the Cuesta de Tocoté Rubber Plantation, situated in a rather wet district of the seaward slope of the Western Cordillera, on the road leading from Calf to Buenaventura. It was soon found that the plantation really consisted of two fully grown trees, said to be 14 years old, another tree about 4 years old and blooming for the first time, and a few dozen seedlings under 1 year of age. According to the owner, the tree was formerly plentiful in the surrounding woods, but it has been so utterly destroyed by rubber gatherers that not a single sapling could be found. The larger tree had attained almost portly dimensions, being about 18 meters high and 65 cm. in diameter and branching at about 2.5 meters from the ground. The smaller tree, of which a picture is given here (pl. 43), was 25 cm. in diameter and about 8 meters high. The leaves of the seedlings are twice as large as those of the grown trees and are generally of a deep purple color. The larger trees bore only young capsules, of which I obtained later some mature specimens, unfortunately all detached from the rachis. On the younger tree there PLATE 42. Vol. 18. erb., H Nat.

At the time of my visit one of the older trees had just been tapped and had given about 500 grams of an amber yellow, translucent scrap rubber, apparently of excellent quality. The collected materials were identified later as belonging to Sapium verum Hemsl., the small noticed differences in the characters of the leaf being ascribed to their rather immature condition. When, however, our herbarium sheets were submitted to the authorities at the Kew Herbarium, they were very emphatic in their belief that my determination was wrong: “The specimen sent as Sapium verum Hemsl. is not that species, and it appears to be distinct from any other in the Kew Herbarium. It has oblong-oblanceolate leaves, acutely cuneate at the base, with sharply serrulate mar- gins, and the upper surface is not papillous, whereas in S. verum the leaves are oblong, obtuse at the base, and the margin is very remotely glandular-denticulate, and the upper surface, when seen through a pocket lens, is minutely papillous.”? The devia- tion in the shape of the leaf and the details of the margin is, as mentioned above, merely an exponent of the undeveloped condition of the former organ. The papille of the upper surface are a general character of the genus, and their absence on a few leaves can not be in any way conclusive. The shape and size of the capsules and seeds, as well as the angle formed by the primary veins and the costa, are far more important and correspond in our specimens with the description given by Mr. Hemsley. Ina further communication from the Kew Gardens it is stated that the seeds ‘‘are identical with a first sample received in 1901 from Mr. R. Thomson, but smaller than those received from the same source in 1890, and figured by Mr. Hemsley in Ic. Plant., pl. 2647, fig. 5-8.’ 1 (See also pl. 44, B, herewith.) Now, I think we have here a fair illustration of the danger of describing a new species on heterogeneous materials. In the plate referred to, figures 2 to 4 represent exactly the seeds which came from the large tree at Tocoté, the smaller tree from which the herbarium specimens were gathered being a seedling obtained from the former. Figures 5 to 8 of thesame plate, however, represent seeds of a distinct species. The seeds received in 1890 accompanied the specimens figured by Hemsley and belonged to them. They were sent by a Mr. R. B. White and were understood to have come from the middle belt, at altitudes of from 2,000 to 2,380 meters, of the mountainous departments of Tolima and Cauca in Colombia. The seeds sent by Mr. R. Thomson in 1901 came from La Mesa, in the State of Cundinamerca, near the upper limit of the lower belt (1,000 meters). They are identical with those accom- panying specimens received by me from El Chaparral, about 800 meters above sea level, in the State of Tolima, through the kindness of Mr. Andrés Roché. These two localities, situated on the opposite watersheds of the Magdalena, are not far distant. The identity of the seeds from La Mesa and El Chaparral is confirmed by the fact that Mr. Thomson sent to Dr. E. M. Holmes, the able curator of the Museum of the Phar- maceutical Society of Great Britain, not only a quantity of these, a few of which were presented to the Kew collections, but also leaves of the tree producing them. Mr. Holmes had the kindness to send me an impression of one of the latter and it agrees in its least details with our specimens from El Chaparral. My attention was first called to the Tolima Sapium by some imperfect and badly prepared herbarium specimens brought from El Chaparral by Mr. C. Wercklé, a botanist residing in San José, Costa Rica. These specimens were sent to Kew with those from Tocoté and were referred to S. verum Hemsl., while the latter were pro- + This explanation is in contradiction with those given by Mr. Hemsley in the text accompanying plate 2647. Figures 2 to 4 were drawn from specimens supplied by Mr. White and correspond evidently with his herbarium specimens, while figures 5 to 8 represent seeds sent by Mr. Thomson. The sources, consequently, are not the same, and the localities whence the samples came are far apart geographically and as to climate. 72 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, nounced distinct. These Chaparral samples differ, however, from the species described by Mr. Hemsley in several details, which are better seen in the new mate- rials which I succeeded later in obtaining from the same locality. The materials at hand enable me to show conclusively that the rubber tree of the lower part of Tolima is quite distinct from the S. verum growing at high altitudes. Perusing now the literature of the subject, I find that Prof. Henri Jumelle, of the Faculty of Sciences of Marseille, gave in 1903! an incomplete description of a Sapium tolimense Hort., which corresponds to our specimens as to the leaves, but shows again confusion as to the seeds, attributing to this species the smaller ones of S. verum. Nevertheless, Professor Jumelle is categorical in his opinion that S. tolimense is distinct from 8. verum: “Tl ne nous est cependant pas possible d’identifier, comme ena tendance Mr. Hemsley, le Sapium tolimense avec le S. verum.’’? The confusion of the seeds again prevents a clear recog- Fia. 77.—Male flower of Sapium tolimense, nition of the fact that the species grow at different a, Floral bud; b, open flower; c,stamens, ltitudes.

In conclusion, the following description, drawn from the specimens sent by Mr. A. Rocha, is believed to show clearly that Sapium tolimense is not a synonym of Sapium verum, but the name of a legitimate and well-characterized species.

It is evidently not that species, but may be 8S. utile or an allied species. (July 15, 1910.) The leaves drop off the branches in drying and it is difficult to get nice specimens, but no doubt they will answer your purpose. I may mention that the leaves of the wee yer much larger when it was younger, say three or four years ago. (August 11, We sent flowering specimens of this tree to Kew in 1907 and they referred it doubt- fully to S. obtusilobum. It did not seem to agree with the figure given in Bull. Herb. Boiss. 6, p. 357 (fig. 17), and I named the tree provisionally 8. utile. This is the first year that the tree has fruited with us and consequently the first time that we could get complete material for identification. You will notice in the figure of 8. obtusilobum in Bull. Herb. Boiss. that the petiolar glands are shown to be at the base of the leaf blade, whereas in our tree these glands are 7 or 8 mm. below the base of the leaf blade. The apical gland is an important character. I find that the capsules are not all sessile, but occasionally one is furnished with a short, thick pedicel. I hope to send you a photogra h of our tree in a few days. Our specimen is a round-headed tree 35 feet high, with a trunk girth of 24 inches at 3 feet from the ground. It is furnished with numerous leafy branches, the lower ones drooping and touching the ground. All parts of the tree, but especially the young shoots and leaves, contain an abundance of milky juice. We received the young plant from the late Mons. PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 75 Chas. Patin in September, 1899, and it was planted out in its present position in October, 1902; Hope, with its dry, hot climate, is probably not the most favorable situation for this tree. The late M. Patin was a planter and Belgian consul at Medellin, Colombia, and I believe the species comes from that neighborhood. M. Patin was keenly interested in plants, especially those of an economic nature, and on his rather frequent visits to Europe or the United States he always stopped at Jamaica and came to see us at the Gardens and usually brought something to add to our collections. He thought very highly of this Sapium as a probable source of rubber and showed me samples of rubber produced by it. He was very anxious to introduce the species to Jamaica, and I find that he brought four plants in 1899, but two were dead and one was very weak and finally succumbed. (September 22, 1910.) The examination of the specimens showed that the tree could not be Sapium utile Preuss, since it belongs to the subsection Cucullata (Pax & Hoffm.); so, in a letter answering those of August 11 (cited above) and 17, and subsequent to that of Septem- ber 22 of Mr. Harris, I expressed the opinion that the species might be either “‘S. obtusilobum Muell.-Arg. or S. hemsleyanum Huber,” coinciding in the first surmise with the tentative identification made at Kew. Further study showed that, while our specimens agreed in almost every detail with the incomplete description of the former by Mueller, they differed in several ways from S. hemsleyanum Huber. The petioles, namely, are longer, the petiolar glands more distant from the blade, the marginal teeth rather distant and obsolete, the primary veins less numerous, the floral spikes shorter and more slender, the basal bract of the male flowers cut straight or hardly rounded, with a fimbriate margin, etc.—all these differences found while comparing our Jamaican specimens with nos. 7509 and 7674 of Jenman from British Guiana. But again S. hemsleyanum is now considered by Dr. Pax! to be the same as, or, at the utmost, a simple form of, a species of broad scope, S. hippomane Meyer, in which our Jamaican specimens can also be included. And as, on the other hand, S. hippo- mane and S. obtusilobum do not seem to differ in any essential details, the texture of the leaf being rather the result of certain environmental conditions, I feel justified in considering also the name S. obtusilobum Muell.-Arg. as merely another synonym for S. hippomane Meyer. The above description and, unless otherwise indicated, the accompanying drawings have been made from our Jamaican materials.

Of the genus Spondias three species, or perhaps only two, have been known hitherto in Central America, one or two of them (S. purpurea, S. dulcis) in a state of semiculti- vation; the other (S. lutea) a large forest tree, which is certainly indigenous, notwith- standing Seemann’s assertion of its having been introduced in Panama. The discovery by Mr. Tonduz of a second native species is highly interesting. SAPOTACEAE. ZAPOTES AND ZAPOTILLOS. In a recent paper! Mr. O. F. Cook has shown that the binomial Achras zapota of the first edition of Linnseus’s Species Plantarum is based upon the type of Plumier’s Sapota; in other words, on the tree known over most of its area in Central and South America as “nfispero,” in Mexico and Guatemala, as “chicozapote,” or errone- ously as “zapote chico,”’ and in the British West Indies as “sapodilla.”’ Mr. Cook agrees in this with the European botanists and any further reference would be uncalled for but for the fact that, owing to a mis- identification of Plumier’s plate, the name Sapota zapotilla Coville was substituted in 1905 and has since been used by the, American botanists who have dealt with that well-known fruit tree of the - Tropics. On the other hand, the naming of an allied species, the zapote tree, also important economically, has resulted in an unfortunate imbroglio. Originally placed in the genus Sideroxylum by Jacquin (1760), then in Achras by Linneus (1762), and used to resuscitate Plumier’s genus Sapota in 1768, it was transferred to Lucuma by Gaertner in 1807 and to Vitellaria by Radlkofer in 1882, while Pierre created successively for it the two names Calospermum and Calocarpum in 1890 and 1904, 1 Nomenclature of the Sapote and Sapodilla, Contr. U. 8. Nat. Herb. 16: 279-282. 1913. Also Journ. Washington Acad. Sci. 3:158-160. 1913. PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 77 the last being rejected in the paper referred to by Mr. Cook, who pro- poses Achradelpha as a definite substitute. This would be the eighth change of the generic status of the zapote tree, an extraordinary fate, indeed, with very few parallels in botanical taxonomy. For brevity’s sake the reasons will not be repeated here why the zapote had no standing in any of the first six of the genera just cited. Those who wish for a full explanation of the case are referred to Mr. Cook’s very complete presentation of it. This 1s the place, however, to state my reasons for differing from my colleague as to the necessity of a new generic name. My contention is that Calocarpum is a perfectly valid name and therefore has to be preserved. It is neither a taxonomic nor even a philologic homonym of Callicarpa. Indeed, the two vocables are so distinct from each other as even to escape in a way the criticism of being synonyms. A taxonomic homonym is a word (the same word with the same spelling, as I understand it) that has been used to name distinct genera. Thus Calospermum, as applied to an alga genus and to the zapote, is both homonymous and homophonous, and had to be rejected in its second application. Donatia Forst., Donatia Bert., and Donatia Loefl. were perfect homonyms, of which only the earliest, first mentioned, could be used. The use of names differing only by their ending in -us, -a, or -um should be absolutely discouraged, as well as that of all those homonymous in the usual sense of the word, that is to say, agreeing in sound and more or less in spelling. But in our case we can reasonably contend that Calli- carpa and Calocarpum are quite heteronymous and can not therefore be confused nor identified as one single term. It is true that these two words are very similar, but they differ in formation, spelling, and pronunciation. The principle of exclusion of generic names should never be extended to such cases, and there is apparently no well- grounded reason to drop Calocarpum and to encumber the already too intricate nomenclature of the genus with a new name. The preservation of Pierre’s name does not interfere in any way with the American method of types and serves as well as any other to perma- nently fix the nomenclature of the zapote type. As to the specific name of the type species, the priority of Calo- carpum sapota over C. mammosum could perhaps be sustained, since Jacquin’s name Siderozylum sapota is anterior by two years to Miller’s Sapota mammosa. But in order to avoid the confusion which may result from the use of a homonymous specific name in two closely related genera, and because mammosum or mammosa has been used through no less than seven changes of the generic name, I agree with Mr. Cook as to the convenience of retaining it as the specific designa- tion of the zapote. 11692°—14——-2 78 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. With reference to the vernacular nomenclature of the same trees, it seems necessary to insist on the fact that the name “chicozapote,” sometimes wrongly given as “‘zapote chico,’”’ as applied to the sapo- dilla, is not intended as a counterpart of “zapote grande,” an expres- sion used rarely, if at all, in connection with Calocarpum mammosum. “‘Chicozapote”’ is simply a modern form of the Nahuatl name “ tzico- zapotl”’, or “gum zapote”’, still used by the native Indians of Mexico. This term, “chicozapote,” besides, is known only in the restricted northwest end of the natural range of Achras zapota and “nispero” isa name of much more general use, borrowed from the Castilian denomi- nation for Mespilus germanica. On the other hand, I do not remem- ber ever having heard the expression “‘zapote grande” used by the natives of Mexico and Guatemala, “zapote” being the name of the fruit all over the natural territory of the species, while in the countries where it has been introduced it has generally been compared with and named after the mamey or mammee (Mammea americana). The spelling of the native name “zapote,” as used by Mr. Cook and authorized by the more recent English dictionaries, is not exempt from criticism. Following the rules of derivation, the z initial should be preserved. That “zapote” proceeds from the Nahuatl “tzapotl” is not a mere supposition, but a well-established fact. In passing to the Spanish language, it has dropped the initial “t,” in accordance with one of its universally adopted rules. ‘‘Zapote” is a Spanish word, figuring in Spanish dictionaries, and as such its original spelling should be respected. ‘Sapodilla”’ is an English name derived from “‘zapotillo.” It is unfortunate that the word was originally mis- spelled, but a mistake once made is no reason for a repetition. As Mr. Cook further observes, “sapodilla” has only a limited use, and that is why I prefer “zapotillo,” which is currently applied to sev- eral species of the same family. Achras zapota L. Sp.

The sapodilla tree is certainly indigenous in Mexico south of the Isthmus of Tehuan- tepec or of a parallel a, little farther north, in Guatemala, and possibly in Salvador and northern Honduras. It is especially abundant in the lowlands of Tabasco and Chiapas and the western part of Yucatan, where lie the principal centers of production of the chicle gum. Farther north, as well as in Nicaragua, Costa Rica, Panama, and the West Indies, it seems to appear only as a cultivated tree. Hum- boldt, in referring to it, says, ‘‘Crescit et colitur prope Cumana, Caracas, etc.”?! It isalso reported by Planchon *as being abundant in the forests of Venezuela and J: amaica, and from my own recent observations I feel also inclined to believe it a native of the former country, as well as of Colombia. \ It was made known from Nicaragua by Oviedo,? who called it the best of all fruits and expressly mentions that it was “in the power of the Indians of the Chorotegan stock (esta fructa estA en poder de los indios de la lengua de los chorotegas), who are known to have migrated from the North, following the coast of the Pacific Ocean as far as Costa Rica. On the eastern seaboard of this last country, however, it is posi- tively said to have been brought from Jamaica in recent times. There do not seem to be any available data as to its introduction into other countries of Tropical America. In Ecuador it was well known in Velasco’s time as a specialty of Quito. We have 1H. B. K.

It may have reached Cuba from Yucatan in prehistoric times and spread from there to the other islands. Although it is seldom met with in Central America and Mexico above 1,000 meters, the upper limit of the tierra caliente, the sapodilla tree reaches far up into the tem- -perate belt of Colombia and is even grown around Quito, in Ecuador, at an altitude of about 2,800 meters. . The adult trees seem to vary greatly in size according to locality. Cook and Collins! give 7 to 9 feet (2 to 3 meters) for its stature in Porto Rico; Jacquin * gives 10 to 15 feet (3 to 5 meters); P. Browne ® says that it “‘rises to a considerable height.”” In Guatemala and Colombia I have often seen specimens 18 theters high and over. As a general rule, it seems that the tree is of a lower stature in the West Indies. The specimens seen by me in Port Limon and on the plains of Santa Clara in Costa Rica were also of less size and more densely foliated than those on the Pacific coast. This can, however, be accounted for by differences of age, climate, and other local con- ditions. Pierre ¢ has described several varieties which have not been found among the numerous specimens investigated in connection with the preparation of this paper.® Frequent and considerable variation was noted in the relative length of the calyx and corolla, or of the latter’s lobules and the staminodes, these being in most cases adherent to the lobules and not free above the insertion of the stamens as represented by Engler.® With reference to the general form of the flowers an old observation of Loefling was confirmed and thus quoted by Jacquin: 7 ‘‘Flores inodori, corolla albida, diu persistentes. Hi ante fecundationem figuram habent ovatam, in ipso autem fecundationis actutoti explicantur magis, ut evadant campanulati; quod, ut ista succedat, antherae inclusae stylusque corolla longior videntur exigere: unde tunc in situ figuraque mutatio partibus accidit insignis. Fecundatione auctem peracta, ovatam denuo assumunt. Extra hunc actum florem descripsisse videtur beatus Loeflingius, cujusmodi ipse illum ego saepissime examinavi: addidi igitur charac- terem, qualem in ipsamet fecundatione semper se mihi exhibuit.”’ , The seeds also vary widely, not only in number but also in shape, as can be seen from the accompanying plate. As to their number, I found that in the Cauca Valley it is usually not over three and very often less, and it was with no little surprise that I saw later in Velasco a reference to the Ecuador fruit as being also 3-seeded, while my own experience in Central America, as well as that of most authors, indicates a larger number. On the occasion of a recent trip to Venezuela, where the fruit is a 1 Contr. U. 8. Nat. Herb. 8: 66. 1903. 2 Loc. cit. 3 Civ. Nat. Hist. Jam. 200. 1789. 4In Urban, Symb. Antill. 5: 97. 1904. 5In the course of my recent investigation of the flora of Panama, I discovered a remarkable variety of this species at Patifio, on the southeastern shore of San Miguel Bay. The tree is rather small, not reaching over 8 meters high; the trunk is straight and the branching divaricate, almost horizontal, with the lower limbs drooping; the crown, the lower part of which is only about 1.5 meters above the ground, is regular and oblong-elongate. The tree was loaded with fruits, these forming dense clusters at the end of the branchlets. The peduncles are 1.5 to 2 meters long; the berries themselves not over 4 cm. in diameter and 3.5 cm. long, globose-depressed in shape; the scaly skin is gray, the mesocarp greenish yellow, and the seeds, usually 5 to 7 in number, always without rostrum. According to the information obtained at the place, the tree is commonly found in the surrounding woods, and goes under the name of ‘‘nispero de monte.”’ 6 Pflanzenfam. 4!: 197. 1889. 7 Stirp.

PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 81 common article of consumption, I investigated a large number of specimens and found the seeds to vary usually in number from 0 to 5. Mr. G. N. Collins, who has paid special attention to the fruits from the economic standpoint in his travels in Central America and the West Indies, has brought back specimens of three types. An ovate and small type (5 to6 cm. long, 4 cm. in diameter) seems to be commonest; another, observed in Jamaica, assumes @ more spherical shape (diameter about 8 cm.) and is considerably larger; while a third, from Oaxaca (Mexico), has just the shape and dimensions (5 cm. high, 8 cm. in diameter) of an ordinary apple. The naseberry or sapodilla is regarded by many as one of the best tropical American fruits. The skin is thin, the meat reddish, somewhat milky, melting, and sweet, with a peculiar flavor. If picked at the right time and handled carefully, this fruit will keep from 8 to 12 days, and there is no reason why it could not reach our markets. Moreover, the broad altitudinal range of the tree above mentioned, that is, between 0 and about 2,800 meters, leads to the supposition that there are well-differentiated and hardy mountain varieties that could be made to grow and, bear fruit farther north in the United States than Florida and southern California, where the Cuban and Mex- ican kinds have been tried with encouraging results. The sapodilla tree has a further importance as being the source of the “chicle’’ or chewing gum of commerce. That substance is the condensed latex of the tree and is extracted on a large scale in the forests of Tabasco and Chiapas, whence it is shipped, mainly to this country. The sapodilla wood is of fine texture, hard, and reddish, with darker veins, and is of current use in the building of the native carts. The infusion of the bark is sometimes administered as a febrifuge, while the seeds are said to be diuretic and very effective also in the cure of certain diseases of the bladder. According to other information, however, the first is only a poor substitute for quinine, and the use of the seeds can provoke serious accidents. On account of the sweetness of its fruits, the sapodilla tree attracts many guests of the animal kingdom, such as birds, bats, squirrels, and others. Jacquin gives a lively description of the struggles that go on under its dense cover, the frugivorous hokkoes, wild turkeys, and other fowls being an easy prey to carnivorous enemies, not excepting’ the native hunter.

The shape of the leaves and fruits, the degree of pubescence of the former and of the flower, the number of the segments of the calyx, etc., are characters which, though subject to variation, have been taken as ground for creating several varieties. The constancy of these it is difficult to prove on account of the scarcity of adequate speci- mens in most herbaria.

PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 83 localities in Central America and the West Indies, 9 were found to have 9 sepals, while 4 had 10 and 2 only 8. The normal number seems to be 9, though Pierre gives 4 to 7 such divisions. The stamens were found to be generally inserted a little lower than the staminodes, indicating that they belong to the inner whorl of the andreecium. The stigma is seldom distinctly or even obscurely radiate, the style ending simply in an obtuse point. Has Calocarpum mammosum ever been found in a truly wild state by botanical collec- tors? It isone of the principal fruit trees in its area and assuch belongs rather to the class of semicultivated plants, like Biza orellana, Mammea americana, Persea gratissima, Crescentia cujete, and others. De la Maza?‘ indicates it as cultivated in Cuba, and Cook and Collins ? say it is rare in Porto Rico. While the product of the cacao tree was highly prized by the Mexicans and constituted the usual beverage among the nobility, Peschel * reports that the peoples of Central America, among them prin- cipally the Chorotegas, gave the preference to the zapote, which was generally culti- vated for a similar use. And again, Juarros* informs us that the sapuyul, or kernel of the zapote seed, was one of the main exchange products of the people of Suchilte- pequez, in Guatemala, at the end of the eighteenth century. According to Mr. G. N. Collins’ the peeled kernels of the same seeds are still offered for sale in the markets of the Isthmus of Tehuantepec. In Nicaragua, Costa Rica, and Panama the zapote tree is often met with in the forests, in isolated specimens, but almost always in places that are known to have been formerly inhabited by man. Notwithstanding the lack of evidence as to the existence of Calocarpum mammosum in the wild condition, it seems that it must be considered a native of Central America. The showy appearance and cleanliness of the seeds may have helped in some wise in the dissemination of the tree. In Santa Marta (Colombia) I have seen them carried as a curiosity by the Indians of the mountains, who did not seem to know the tree and had no name for it, although they readily assimilated it to their own “‘manzana” (Lucuma argoacoensis Karst.). The reddish zapote wood is said by Grosourdy ° to be fine-grained, compact, hard, and apparently suitable for cabinetwork. The supply, however, would always be very limited, as the tree is rather protected by the natives on account of the fruit. Besides, it usually forks very low, so that trunks of any good length are seldom available. The fruit has a thick, juicy mesocarp, of a reddish or pinkish color, and a little sticky on account of the latex it contains. The flavor is sweetish, with a peculiar squashy strain, quite delectable if we believe some Spanish authors, but not generally to the taste of foreigners. This strain might, however, be removed or improved by 1 Gomez de la Maza, Manuel. Nociones de Botanica sistematica. 76. 1893. 2 Contr. U. S. Nat. Herb. 8: 178. 1903. 3 Peschel, Oscar.

Historia de la ciudad de Guatemala, edicién del Museo euatemalteco 23. 1857. As the note here referred to is a very interesting addition to the economic history of the zapote tree, it is well to reproduce it in whole: “ Sapuyul es la almendra del zapote, fruta como de medio pié de largo: la almendra tiene de dos 4 tres pulgadas: se halla dentro de una cdscara, como la de la avellana; sobre ella hay una médula de color encarnado, tan hermosa 4 la vista como deleitosa al gusto, y encima de esta una corteza un poco dura. Los Indios y gente pobre se sirven del sapuyul para hacer chocolate, mezcléndolo con cacao: es tanta la abun- dancia de zapotes en esta provincia, que botan la fruta, por cojer el sapuyul, y éste tiene tal consumo, que solo en la plaza de Quezaltenango se venden de cuatro 4 cinco mil pesos de dicha almendra al afio.”’ 5 Manuscript notes. 6 Grosourdy, Renéde, M.

That same mesocarp can also be turned into an excellent marmalade, or into jelly, and although the fruit does not yet seem to have met with any great favor in our markets, it is not altogether without importance among tropical fruits. The seed contains a large, oily almond, which has a strong smell and a bitter taste. According to de la Maza! it has stupefying properties. Grosourdy calls it a diuretic, and in Costa Rica the oil is used in the treatment of persistent catarrhal complaints, while the whole almond, finely ground, is made into an exquisite confection.? More- over, as seen above, it seems to have been extensively used, and is still used on a small scale, in conjunction with cacao, in the preparation of the current beverage of the natives of Central America. It is called ‘‘sapuyul” (Nahuatl tzap-ullul, i. e., zapote resin or gum?). According to Mr. G. N. Collins (MS. notes), the Kekchi Indians of Verapaz still use it in the preparation of a drink, in conjunction with cacao and parched corn; it imparts a bitter taste to the beverage. These Indians gather all the seeds they find along the trail; the almonds are first boiled, then roasted and grated. As a historical memorandum, we may also mention that during the first half of the nineteenth century the same seed was still used in Costa Rica in lieu of the present iron to smooth starched white linen.® EXPLANATION OF PLATES 48-51.—All from photographs taken by G.

This species, which curiously enough seems to have hitherto escaped the attention of botanists, is closely related to Achras mammosa, differing, nevertheless, by the smaller leaves, downy and white beneath, the smaller and differently shaped sepals, the shorter staminodes and stamens, the latter with broadly ovate anthers, and above all the comparatively small, green, and thin- skinned fruit and the smaller, ovate seed. Morelet? calls it Lucuma salicifolia, but there can be no possi- ble confusion with that Mexican species of Humboldt and Bonpland. Calocarpum viride is known so far only from Guatemala (where it seems to be rather frequent in Alta Verapaz), from Honduras, and from Costa Rica. It is likely to be found in all the intervening region.

Corolla broad, 10 to 11 mm. long, 5 or 6 lobed, pubescent outside, the margins minutely ciliate or denticulate ; lobes ovate, equal in length to the tube, rounded at the tip. Staminodes 5, 3.5 to 4 mm. long, papillose, linear, rounded-obtuse at the end, alternating with and one-third shorter than the corolla lobes. Stamens 5, 2 to 3.5 mm. long, glabrous, inserted a little lower than the staminodes; filaments short, attenuate at tip; anthers extrorse, ovate or ovate-elliptic, slightly emarginate at base. Pistil about 10 mm. long; ovary rounded, 6-celled, densely hairy; style smooth; stigma obtuse, hardly distinct from the style. Fruits fusiform, 1-seeded, 10 to 12 cm. long, 4 to 5 em. in diameter, rounded at base with the persistent, 5-parted calyx attached, attenuate and rounded-obtuse at the tip (and often with a lateral stigmatic spot). Skin thick, leathery, smooth, yellow; pulp mealy, sweet, edible, the color and consistence of the yolk of a hard-boiled egg. Seed fusiform, 4 to 5 cm. long, 1.5 to 2 cm. in diameter, apiculate at the hilum end, light brown and polished outside the umbilical area, this broad, elliptic-elongate, neither impressed nor salient, whitish and almost smooth. Description based on the fine Costa Rican specimens sent by Mr. O. Jimé- nez Luthmer (no. 513). Mexico: The species was originally described from this country upon spee- imensor notes obtained from Cervantes by Bonpland. The fruit and seed are described and figured here probably for the first time.

Costa Rica: Occasionally cultivated in the valley of San Jose, but never met with in a wild condition. Panama: Vicinity of Penonomé, Province of Coclé, in the zone below 300 meters, flowers, between February 23 and March 22, 1908, R. S. Williams 56 (U. 8. National Herbarium, no. 677891). There is no indication as to the presence or absence of the species in the northern and middle part of Central America, but it is very likely to be met with in that inter- vening region. COMMON NAMES: Mexico—Central Mexico and Guanajuato, zapote borracho; Oaxaca and Morelos, zapote amarillo; Guadalajara, mamey de Cartagena; Michoacan, huicwmo (Safford), Costa Rica, zapotillo, siguapa, and canistel, the latter probably from “canisté,”? the Maya name for Lucuma multiflora. This species seems to vary as to pubescence, number and disposition of flowers, etc., the only really constant characters being those shown by the fruit and seed. In the absence of these it is likely that several forms of L. salicifolia have been described as distinct species. FXPLANATION OF PLATES 55,56.—From photographs taken by C. B.

A large part of the paper consists of descriptions and nomenclatorial changes in the Amaranthaceae and Allioniaceae incidental to monographic work upon these families. Two new genera are proposed in the Malvaceae. FREDERICK V. CovILLE, Curator of the United States National Herbarium. II CONTENTS.

The present paper is in continuation of a series begun in 1914." It contains descriptions of new species and taxonomic notes upon various groups of plants, but chiefly the Amaranthaceae, Allioniaceae, Mal- vaceae, and Rubiaceae, and the group of families formerly known as the Leguminosae. There are included descriptions of two new genera in the Malvaceae. The new species described are based chiefly upon the extensive col- lections obtained in Panama by Mr. H. Pittier. Study of the Panama collections shows very clearly the close alliance of the flora of the Isthmus with that of Colombia, as was to be expected. Quite unfore- seen, however, is its inclusion of certain genera which are character- istically Brazilian, a fact recently pointed out by Mr. Pittier.2 Two Brazilian genera, Cassupa and Stachyarrhena, are here reported for the first time from North America. Moreover, several of the species described as new have their closest allies in Brazilian plants. NEW CYPERACEAE FROM PANAMA. While working with the Cyperaceae of Panama, the writer discov- ered two apparently undescribed species, a Rynchospora and a Scleria, descriptions of which are published below. The Rynchospora is particularly interesting, being very unlike any species previously reported from North America. There are also included new combinations in Cyperus, Stenophyllus, and Calyptrocarya, which are necessary for properly listing the Panama Cyperaceae. Rynchospora argentea Standley, sp. nov. Tufted perennial; leaves 30 to 40 cm. long, 2 to 3 cm. wide, acuminate, narrowed at the base into broadly winged petioles, prominently nerved, scabrous on the margins, elsewhere glabrous, silvery white, especially on the upper surface, at least when dry; 1Contr.

Sci. 5: 468-469, 1915. 87 88 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, inflorescence 20 cm. long or less, much shorter than the leaves, nearly naked, bearing only 1 or 2 much reduced thin pale leaves, paniculate but only sparingly branched, the branches angled, glabrous; spikelets solitary, on peduncles 1.5 to 3 mm. long; empty scales several, nearly white, hyaline, lanceolate or oblong, acute, with short subulate tips, glabrous except for the scaberulous midnerve; bristles of the involucre 6, white, scaberulous; style branches very short; fruit not seen. Type in the U. 8. National Herbarium, no. 679431, collected on high hills back of Puerto Obaldia, on the San Blas Coast, Panama, August, 1911, by H. Pittier (no. 4307). In general appearance this is very unlike any other species of which material or descriptions have been seen. Its broad, elongated, silvery leaves and the very short inflorescence, nearly leafless and bearing but few spikelets, will enable one to recog- nize it readily. Scleria hitchcockii Standley, sp. nov. Underground parts not seen; plants slender, about 70 cm. high, rather sparingly leafy; culms triquetrous, sharply angled, striate, yellowish green, obscurely scaberu- lous; sheaths closely investing the culms and nearly covering them, 3 to 5 cm, long, sharply angled, striate, glabrous, or hirsutulous near the summit; ligule very short, about 1 mm. long, truncate, hirsute; leaf blades 12 to 18 cm. long, narrow, 2 to 4mm. wide, yellowish green, acute, conspicuously nerved, nearly glabrous, but often hirsute-ciliate on the margins and on the midvein beneath; inflorescence much exserted, on a slender peduncle; panicle about 11 cm. long, composed of few very slender spikes, the branches short-ciliate on the angles; bract subtending the inflores- cence 3.5 cm. long, very narrow; spikelets in sessile fascicles of 2, each consisting of one fertile and one sterile flower; glumes of the fertile flower about 2 mm. long, reddish brown, ovate, oblong-ovate, or lanceolate, thin, strongly keeled, the midnerve extended as a short awn; glumes of the sterile flowers slightly longer, about 3 mm. long, nar- rower; achenes smooth and shining, white, spherical or depressed, 1.2 mm. in diameter, disk fused with the achenes as a short thick stipe. Type in the U.S. National Herbarium, no. 678393, collected on a grassy hillside in the foothills near El Boquete, Province of Chiriqui, Panama, altitude 1,000 to 1,300 meters, September 28 to October 7, 1911, by A. 8. Hitchcock (no. 8326). The proposed species is related to Scleria lithosperma, but differs conspicuously in the slender branches, short scales of the flowers, and small, depressed achenes.

NEW AMARANTHACEAE FROM TROPICAL NORTH AMERICA. Recently the writer has been engaged in monographing the family Amaranthaceae for the North American Flora. In a group to which so little attention had been given it was to be expected that more STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 89 than a few new species would be discovered. Some of these have been published during the past year. A considerable number of others, chiefly in the genera Iresine and Achyranthes, are described in the present paper. The name Achyranthes is here used for the genus generally known as Alternanthera. The reasons for the use of the name in this sense the writer has recently explained at length.? He has also published a synoptic account of the North American representatives of the family.* Achyranthes panamensis Standley, sp. nov. Stems weak and probably clambering over shrubs, herbaceous, much branched, the branches slender, angulate, short-pilose with solitary or fasciculate, spreading or reflexed hairs; petioles 1 to 4 mm. long; leaf blades oblong-elliptic or ovate- oblong, 2 to 5.5 cm. long, 0.6 to 2 cm. wide, acute or acuminate, acutish at the base, firm, bright green, appressed-pilose on both surfaces with short slender fulvous hairs; peduncles axillary and terminal, simple or usually branched, 1 to 6 cm. long, slender, densely short-pilose; spikes usually solitary, globose-ovoid or short-cylindric, 8 to 11 mm. long, 7 mm. thick; bracts broadly ovate, acuminate, glabrous; bractlets broadly ovate, half as long as the sepals, aristate-acuminate, sparsely short-villous; sepals lance-oblong, 2.5 mm. long, acute or acutish, 3-nerved, purplish (brownish or fuscous when dry), glabrous; filaments short, linear-subulate; staminodia equaling or exceed- ing the anthers, two-thirds as long as the sepals or shorter, lacerate at the apex; style short, the stigma entire; seed subglobose, 1 mm, long, black and shining. Type in the Herbarium of Columbia College (New York Botanical Garden), collected in Panama by Sutton Hayes (no. 944). In floral characters this plant is similar to Achyranthes mexicana (Schlecht. & Cham.) Standley, but in that species the slender peduncles are simple and the flowers are white or slightly stramineous. Achyranthes williamsii Standley, sp. nov. Stems herbaceous, clambering over shrubs and herbs, sparsely branched, the branches stout, striate, cinereous-puberulent; petioles stout, 2 to 10 mm. long: leaf blades oblong, ovate-oblong, or rarely elliptic, 2.5 to 8 cm. long, 8 to 33 mm. wide, acute, acutish, or obtuse at the apex, acute or obtuse at the base, pubescent on both surfaces with very short, lightly appressed hairs, bright green, rather thick; peduncles axillary, simple or rarely branched, 2 to 6 cm. long, stout, cinereous or glabrate; heads solitary, short-cylindric or ovoid, 1 to 3 cm. long, 10 to 12 mm. thick; bracts broadly ovate, acuminate, glabrous; bractlets half as long as the sepals, ovate, aristate-acuminate, short-pilose; sepals narrowly lance-oblong, 5 mm. long, acuminate, whitish or stramin- eous, 3-nerved, short-pilose, the tips slightly spreading; filaments very short, the staminodia ligulate, longer than the anthers and slightly shorter than the sepals, lacerate at the apex; style evident, the stigma entire. Type in the U. 8. National Herbarium, no. 678206, collected near Citura, Panama, April 14, 1908, by R. S. Williams (no. 675). 1 Standley, Paul C. New or notable species of Amaranthus. Bull.

Nicaracua: San Juan del Sur, Torrey (Herb. Gray). Island Ometepe, Lake Nicaragua, January, 1893, C. L. Smith (Herb. Gray). This plant has no very close relatives among the previously described species reported from Central America, unless it may be Achyranthes pycnantha (Benth.) Standley. In that the sepals are densely long-pilose and 6 to 7 mm. long, the leaves are nearly glabrous, and the peduncles are usually branched. Achyranthes stenophylla Standley, sp. nov. Stems slender, branched, the branches ascending or suberect, striate, very sparsely pilose or glabrate; leaves numerous, the internodes short, the petioles 2 to 10 mm. long; leaf blades linear to elliptic-linear, 2.5 to 5 em. long, 3 to6 mm, wide, acute or acutish, acuminate at the base, very sparsely appressed-pilose or glabrate; peduncles axillary, simple, 2 to 5 cm. long, short-pilose, very slender; spikes ovoid or short-cylindric, 6 to 10 mm. long,6 mm. thick; bracts broadly ovate, acute, glabrous: bractlets half as long as the sepals, acuminate, long-aristate, sparsely short-villous; sepals lance-oblong, 2.5 mm. long, acute or acutish, membranaceous, 3-nerved, sparsely short-pilose, stramineous, the tips erect or slightly incurved; filaments short, the staminodia ligulate, longer than the anthers, two-thirds as long as the sepals, lacerate at the apex; style evident, the stigma entire. Type in the Herbarium of Columbia College (New York Botanical Garden), col- lected in Panama by Sutton Hayes (no. 941). This plant belongs to the same group as A. pycnantha, A. williamsii, and A. cordo- bensis, but it is very distinct from all of them in its smaller spikes and very narrow leaves. Achyranthes laguroides Standley, sp. nov. Erect or ascending, suffruticose below, the stems 1 meter long or less, much branched, the branches striate, sparsely pilose-strigose or glabrate; leaves very shortly petiolate, the blades narrowly lanceolate to elliptic-linear, 1.5 to 5.5 cm. long, 2 to 6 mm. wide, acuminate or attenuate at both ends, pilose-sericeous, densely so beneath; peduncles simple or branched, 5 to 20 mm. long, or the heads often sessile or subsessile, the pedun- cles densely pilose-sericeous; spikes ovoid or short-cylindric, 1 to 2 em. long, 9 mm. thick, the flowers whitish-stramineous; bracts and bractlets ovate-triangular, half as long as the sepals, acuminate or long-acuminate, sparsely pilose or glabrate; sepals linear-oblong, 4 to 5 mm, long, acuminate, membranaceous, l-nerved, pilose near the base with straight erect jointed white hairs, these equaling or slightly exceeding the sepals; stamen tube elongate, the antheriferous lobes short; staminodia ligulate, exceeding the anthers, deeply and acutely laciniate at the apex; style elongate. Type in the U. 8. National Herbarium, no. 471849, collected near San Francisco de Guadalupe, Costa Rica, May, 1893, by A. Tonduz (Inst. Fis. Geogr. Costa Rica no, 8006). There is a specimen of the same plant in the herbarium of the Missouri Botan- ical Garden, collected somewhere in Costa Rica in April, 1910, by G. C. Worthen. The species is a very distinct one. It is to be placed nearest Achyranthes stenophylla, but that has flowers only half as large and sparsely short-pilose sepals, Achyranthes cordobensis Standley, sp, nov. Plants much branched, the branches spreading, loosely short-pilose, or glabrate in age; petioles 1 to 3 mm. long; leaf blades ovate-oblong or oval, or the uppermost lance-oblong, 3 to 6 cm. long, 8 to 20 mm. wide, rather abruptly long-acuminate, obtuse at the base, thin, densely pilose-sericeous beneath, less densely so on the upper surface; peduncles simple, axillary, 2 to 6 cm. long, pilose with ascending hairs; spikes solitary, rarely sessile, ovoid or short-cylindric, 8 to 15 mm. long, 11 mm. thick; STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 91 bracts and bractlets half as long as the sepals, broadly ovate, aristate-acuminate, subscarious, stramineous; sepals lance-oblong, 5 mm. long, acutish, subcartilaginous in age, 3-nerved, stramineous, sparsely short-pilose, the tips slightly spreading; stamen tube short; staminodia much exceeding the anthers, less than half as long as the sepals, ligulate, deeply fimbriate at the apex; style evident, the stigma entire. Type in the U. 8. National Herbarium, no. 125547, collected in the Valley of Cérdoba, Mexico, February 11, 1866, by Bourgeau (no. 1946). Related to A. williamsii, described above, but differing in the long-acuminate or abruptly acuminate leaves, which are densely pilose-sericeous beneath, and in the merely acutish, rather than acuminate, sepals.

The species appears to be very abundant in the Greater Antilles and along the eastern coast of Central America, occurring chiefly as a weed in waste or cultivated ground. It has always been confused with Gomphrena decumbens Jacq., described in 1804. It is remarkable that a plant so common in the West Indies has never received a name, but apparently no one has ever questioned its identity with Jacquin’s species. Gomphrena decumbens was described! from cultivated specimens whose origin was not known. The description is ample and fortunately is accompanied by an excellent plate. There is no doubt that it applies to a plant which is common from eastern and central Mexico to Guatemala and is found also in South America. So far as the writer knows, it does not occur in the West Indies. It differs from Gomphrena dispersa in having the crests of the bractlets widest much below the apex, if they are perceptibly widest anywhere, the flowers thus appearing pointed or acuminate. Moreover, the bractlets are much longer than the flowers, while in G. dispersa they equal or are shorter than the perianth. In the latter species the crests are widest at or near the apex of the bractlets, and the flowers thus appear obtuse or merely acutish. In Gomphrena decumbens, furthermore, the flowers are very frequently tinged with red, or are yellowish, while in the proposed new species they are a dull, clear white. It is very probable that G. dispersa is to be found also in northern South America, but so far no specimens have been seen nor do any of the descriptions of species from that region appear to apply to it. Gomphrena parviceps Standley, sp. nov. Gomphrena decumbens pringlei Stuchlfk, Repert. Nov. Sp. Fedde 11: 156. 1912, in part, not G. pringlei Coult. & Fish. 1892. Prostrate or procumbent annual, much branched, the stems 10 to 30 cm. long, slender or stout, often tinged with red, appressed-pilose; leaves numerous, subsessile, the blades oblong or spatulate, 1 to 3.5 cm. long, 4 to 10 mm. wide, rounded or obtuse at the apex, acutish at the base, green, appressed-pilose beneath, glabrate above; spikes solitary or glomerate, terminal or axillary, subglobose, 7 mm. in diameter, each spike or cluster of spikes subtended by 2 or several sessile leaves, these usually 2 to 3 times as long as the spikes; bracts broadly ovate, acuminate; bractlets 3 mm. long, scarious, white, tinged with pink, twice as long as the bracts, narrowly cristate at the apex, the crest obscurely denticulate, pink or white; perianth conspicuously exceed- ing the bractlets, the lobes oblong, obtuse, truncate, or emarginate at the apex, the outer ones subcoriaceous, white or pink, glabrous, the inner ones thin, bright green except along the margin, very sparsely lanate; stamen tube about equaling the perianth; style elongate, the stigmas filiform; seed ovoid, 1.5 mm. long, reddish brown. Type in the U. 8. National Herbarium, no. 354471, collected in the Valley of Mexico, Federal District, Mexico, altitude 2,190 meters, October 3, 1899, by C. G. Pringle (no. 8251). Related to Gomphrena pringlei Coult. & Fish., but in that species the calyx lobes are acute and the perianth merely equals the bractlets instead of exceeding them. Gossypianthus brittonii Standley, sp. nov. Caudex much branched both above and below the surface of the soil, the branches stout or slender; stems numerous, prostrate, 4 to 9 cm. long, slender, lanate when young but soon glabrate; basal leaves petiolate, the blades oblanceolate, 6 to 8 mm. long, 1.5 to 2 mm. wide, obtuse or acutish, pilose above, pilose-sericeous beneath; cauline leaves short-petiolate, the blades orbicular to oval, 2 to 4 mm. long, obtuse or rounded at the apex, glabrate above, pilose beneath; flowers glomerate, the glomer- * Jacq.

STANDLEY—TROPICAL AMERICAN PHANEROGAMS, 93 ules much longer than the subtending leaves; bracts ovate to orbicular-ovate, nearly equaling the sepals, obtuse or rounded at the apex, white, scarious, glabrous; sepals 2.5 to 3 mm. long, lance-oblong, acute, faintly 3-nerved, green along the nerves, the margins white and scarious; filaments linear, dilated at the base; utricle oval; seed oval, 1.2 mm. long, brown, shining. Type in the herbarium of the New York Botanical Garden, collected on arocky hill in a palm barren, Santa Clara, Cuba, April, 1912, by N. L. Britton and J. F. Cowell (no. 13318). Apparently there are two species of Gossypianthus in the West Indies. One of these, G. lanuginosus, was described from Santo Domingo, and is known also from Mexico and Texas. In the Bernhardi Herbarium (Herb. Mo. Bot. Gard.) there is a specimen from Santo Domingo, labeled Achyranthes piloselloides Poit., which agrees in all respects with the common Texan plant. The Cuban Gossypianthus is appar- ently distinct in having obtuse rather than acute or acuminate bracts and bractlets, a much branched caudex, and much smaller leaves. Iresine acicularis Standley, sp. nov. Stems erect, stout, very sparsely pubescent with short slender hairs, the internodes 10 to 23 cm. long; petioles slender, 1 to 5.5 cm. long; leaf blades ovate or broadly ovate, 6.5 to 20 cm. long, 3.5 to 10 cm. wide, or those within the inflorescence some- what smaller, rather abruptly long-attenuate or acute, rounded or obtuse at the base and abruptly short-decurrent, thin, bright green, very sparsely villous on the upper surface with short remote soft yellowish white hairs, similarly pubescent beneath and furnished in addition with numerous appressed shining amber-colored or bright yellow acicular hairs, villous-ciliate, rather prominently veined, but the veins slender, diverging at angles of from 50 to 70 degrees; inflorescence a broad, dense, somewhat leafy panicle, 25 cm. long and 15 cm. broad, the rachises sparsely villous and bearing in addition numerous stout, acicular, glistening amber-colored or yellow hairs, these most abundant at the base of the spikelets; spikelets alternate, pediceled or sessile, densely flowered, stout, 4 to 12 mm. long; bracts white, rounded-ovate to narrowly ovate, acute, from half as long to fully as long as the sepals; sepals about 1.5 mm. long, narrowly oblong, acute, those of the pistillate flowers 3-nerved, the flowers furnished at the base with copious long white wool; staminal cup not lobed; utricle shorter than the sepals; seed suborbicular, 0.5 mm. in diameter, dark reddish brown, shining. Type in the U. 8. National Herbarium, no. 399603, collected on the Volcdn de Fuego, Department of Sacatepequez, Guatemala, at an altitude of 2,700 meters, Feb- ruary 20, 1905, by W. A.

The proposed species is related to Iresine celosioides L., but is distinguished by the dentate bracts, and more strongly by the peculiar pubescence of the inflorescence. No other species of the genus is known to have trichomes of the same form. Iresine arenaria Standley, sp. nov. Erect perennial, suffrutescent at the base, much branched, the branches slender, erect-ascending, green, striate, glabrous; petioles slender, 4 to 5 mm. long; leaf blades linear to narrowly ovate, 2.5 to 4.5 cm. long, 2 to 12 mm. wide, acute or acumi- nate, obtuse to acuminate at the base, rather thick, deep green, glabrous; flowers polygamous, narrowly paniculate, the panicles open or congested, nearly naked, 4 to 20 cm. long, the branches slender or stout, ascending, short, the spikelets few, short or elongate, pedunculate or sessile, the rachis densely lanate; bracts and bractlets rounded-ovate, obtuse or acutish, short-cuspidate, hyaline, whitish-stramineous, 94 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. densely short-villous; sepals oblong-oval, 1.5 mm. long, rounded at the apex, 3-nerved, densely pilose with soft white hairs; filaments subulate-linear, shorter than the sepals, the staminodia one-third as long as the filaments, narrowly triangular, entire; style short, the stigmas slender; utricle orbicular, compressed; seed orbicular, 1 mm. broad, dark reddish brown, shining.

Acad. 21: 454, 1886, There are very few North American species of Iresine which have so extensive a list of synonyms as the present species. Usually it has been known as Jresine latifolia (Mart. & Gal.) Benth. & Hook., but that name is homonymous and consequently not available, In spite of the fact that Ibéfiez uses several large pages of text and a col- ored plate to characterize his proposed species, the present writer is not absolutely certain that that plant is the same as the one heretofore known as Iresine latifolia. Ibafiez’s description, however, applies better to the latter species than to any other of which the writer has seen specimens, and his material came from a region in which I, latifolia is known to grow; for which reasons it seems best to use Ibéfiez’s name in this application, at least for the present. Iresine costaricensis Standley, sp. nov. Scandent shrub, much branched, the branches stout, terete, smooth, the younger ones and those of the inflorescence densely pubescent with short stout appressed ful- vous hairs; petioles stout, 7 to 17 mm. long; leaf blades oval to oblong-elliptic, 11 to 18 cm. long, 4 to 7 cm. wide, abruptly acuminate or long-attenuate, obtuse at the base, thick, sparsely short-villous on the upper surface and deep green, appressed-pilose beneath with slender stiff hairs; flowers perfect, in a loose, much branched, naked, terminal panicle sometimes 50 cm. long, the branches slender, spreading, opposite or verticillate, the spikelets 3 mm, thick or less, sessile, few-flowered, the rachis canes- cent; bracts and bractlets less than half as long as the sepals, suborbicular, fuscous- stramineous, sparsely short-villous; sepals oval-oblong, 1.5 mm. long, obtuse, 3-nerved, brownish-fuscous, densely pilose, the hairs stiff, grayish, scarcely exceeding the sepals; filaments shorter than the sepals, the staminodia short, entire; style short, the stigmas short and stout. Type in the U.S. National Herbarium, no. 861225, collected at Las Vueltas, Tucu- rrique, Costa Rica, in 1899, by A. Tonduz (Inst. Fis. Geogr. Costa Rica, no, 13183). Also collected at the same locality by the same collector in 1898 (no. 12919). The proposed species belongs to that section of the genus which was once given generic rank by Martius under the name Trommsdorffia. It is a relative of Iresine argentata (Mart.) D, Dietr., a species occurring in Porto Rico, Colombia, and Venezuela, which has larger flowers, mostly pedunculate spikelets, and acute or abruptly acute leaf blades.

Purpus (no. 5864), this also in the herbarium of the University of California. A very distinct species, because of the prevailingly suborbicular leaves and the peculiar form of the staminate inflorescence.

Shrub; branches slender, terete, smooth, the young ones and those of the inflo- rescence densely canescent; petioles stout, 3 to 7 mm. long; leaf blades obovate- oblong or oval-oblong, broadest above the middle, 7 to 9 cm. long, 3 to 4 cm. wide, acute at the apex, acute or acuminate at the base, rather thin, sparsely appressed- pilose beneath or glabrate; flowers perfect, paniculate, the panicles pyramidal, loosely branched, naked, the branches spreading, opposite, the spikelets short, pedunculate or sessile; bracts and bractlets one-third as long as the sepals, suborbicular, stramineous, sparsely short-villous or glabrate; sepals elliptic-oblong, 2.5 mm. long, acute, brownish- fuscous, faintly nerved, short-villous at the apex, pilose at the base, the hairs sordid white, stiff, about equaling the sepals; filaments filiform, shorter than the sepals, the staminodia very short, entire; style short, the stigmas short and stout. 5431°—16——2 98 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. Type in the U. 8. National Herbarium, no. 48566, collected in Nicaragua by Charles Wright. This, like Iresine costaricensis, is related to I. argentata. It differs from the latter, however, in having thin rather than subcoriaceous leaf blades, which are acute at the base and broadest above the middle, rather than rounded at the base and broadest at or below the middle. NEW OR NOTABLE ALLIONIACEAE. In the course of preparing a monograph of the North American representatives of the genus Torrubia two undescribed species have been discovered—one from Mexico and one from Guadeloupe. This group has usually been referred to Pisonia, but several years ago Dr. N. L. Britton showed ' the inconsistency of retaining it in that genus, and transferred to it all the West Indian species then known. A number of West Indian species of Pisonia have since been described which are properly referable to Torrubia and are here transferred to that genus. At the same time it seems desirable to make the proper nomenclatorial combinations for the South American species of Tor- rubia. There is appended also a description of a new Panamanian species of the closely related genus Neca. Several years ago the writer proposed the name Commicarpus ? for that section of the genus Boerhaavia having glanduliferous fruits borne in umbels or verticels. The genus is well marked, besides, by the scandent habit of the plants. At the time the new genus was proposed only the Mexican species were transferred to it. Most of the other species are African. The writer takes this opportunity of transferring them, also, to Commicarpus. Two South American Allioniaceae, also, described as species of Mirabilis, are here transferred to Allionia. Neea delicatula Standley, sp. nov. Branches slender, greenish gray, glabrous, the branchlets slender, ferrugino-puber- ulent when young but soon glabrate, the internodes short; petioles slender, 4 to 7 mm. long; leaves alternate, the blades elliptic, elliptic-obovate, or oblong-oval, 2.2 to 6 cm. long, 9 to 20 mm. wide, cuneate to acutish at the base, abruptly acuminate at the apex, the tip narrowly triangular, acutish or usually obtuse, the blades thin, deep green, concolorous, glabrous and dull on the upper surface, sparsely rufo-puberu- lent beneath along the midvein, the margins plane, the lateral veins obsolete or nearly so; peduncles of the staminate cymes 2.2 to 4.5 cm. long, terminal and axillary, nearly filiform, flexuous, glabrous, the cymes few or many-flowered, 2 to 5 cm. wide, the flowers on slender pedicels 4 to 15 mm. long; bractlets triangular-oblong, acute, 1 mm. long, puberulent; staminate perianth urceolate, acutish at the base, 4.5 mm. long, 3mm. wide, puberulent at the apex, elsewhere glabrate, minutely 5-dentate; stamens 7, the filaments very unequal, the anthers 1 mm. long; pistillate flowers and fruit not known. 1 Bull, Torrey Club 81: 611-615. 1904. ?

Type in the U. 8. National Herbarium, no. 592420, collected in Guadeloupe, April 15, 1893, by Pére Duss (no. 2170). Related to Torrubia fragrans, but distinct in the large, nearly glabrous staminate perianth and the glabrous branches of the inflorescence. Torrubia potosina Standley, sp. nov. Branches slender, grayish, striolate, the branchlets slender, sparsely ferrugino- puberulent when young, the internodes 1.5 to 7 cm. long; leaves opposite, subequal or unequal, the petioles slender, 4 to 6 mm. long, sparsely ferrugino-puberulent; leaf blades oval or oblong-oval, rarely orbicular-oval, 5 to 10.5, or rarely only 3.5, cm. long, 2.2 to 5 cm. wide, rounded or acutish at the base, acute or usually cuspidately acute or acuminate at the apex, thin, glabrous, concolorous, slightly lustrous on the upper surface, the lateral veins prominent, divergent, nearly straight, about 8 on each side, laxly anastomosing near the margins, the secondary veins laxly and inconspicuously reticulate; pistillate peduncles terminal and axillary, 2.5 to 7.5 cm. long, very slender, sparsely puberulent or glabrous, the inflorescence few-flowered, cymose-paniculate, 1.5 to 3.5 cm. long, the branches opposite or dichotomous, divergent, sparsely ferru- gino-puberulent, the flowers solitary or in cymules of 3, sessile or on pedicels 4 mm. long or shorter, the bractlets acute, about 0.5 mm. long, puberulent; pistillate perianth elliptic-oblong, 2.5 to 3 mm. long, slightly constricted in the throat, sparsely puberu- lent, the teeth triangular, acute, erect; anthocarp oval, 7 mm. long and 4.5 mm. in diameter; fruit finely striate; seed elliptic-oblong, 6 mm. long and 2.5 to 3 mm. in diameter, brown. Type in the U. 8. National Herbarium, no. 570197, collected near Rascén, San Luis Potosi, Mexico, June, 1905, by Edward Palmer (no. 675). The proposed species is of particular interest, since it is the second Torrubia to be reported north of Costa Rica. The other Mexican species, 7. linearibracteata, has been described only recently, from Yucatan. Torrubia potosina is related, apparently, to T. costaricana and T’. linearibracteata, but differs from both in its lax, few-flowered inflorescence and broader leaves. 100 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM.

NEW CAESALPINIACEAE FROM PANAMA. The genus Cassia is represented in Panama by at least 20 species of diverse forms. Three of them appear to be new and are described here. There occur in the same region 10 species of Chamaccrista, one of which is undescribed. In this connection there are included also two new combinations in Chamaecrista, for species occurring in Panama. Cassia falcinella Standley, sp. nov. Stems terete or very obscurely 5-angled, striate, copiously cinereous-puberulent with tawny hairs; leaves numerous, approximate; stipules lingar, falcate, 10 mm. long, 0.75 mm. wide, green, nerved, subulate-tipped, cinereous-puberulent; rachis of _ the leaf about 35 mm. long, tipped with a subulate appendage 3 mm. long, the lower pair of leaflets borne 20 to 25 mm. above the base; petiolar glands 2, one or rarely 2 glands borne between each pair of leaflets, 2 to 3 mm. long, slender-cylindric or rarely conic, acute, black; leaflets 2 pairs, asymmetrical, oblong-obovate to elliptic-oblong, 5 to 8 cm. long, 2 to 4 cm. wide, abruptly long-acuminate at the apex, the tip acute, 14 mm, long or less, obtuse or rounded and unequal at the base, firm in texture, subcoriaceous, glabrous, lustrous on the upper surface, concolorous, conspicuously veined; inflorescence a dense many-flowered leafy terminal panicle, its branches densely cinereous-puberulent with yellow hairs; peduncles rather stout, 7 to 18 mm, long; bracts similar to the stipules but shorter and thinner, some of them narrowly linear-lanceolate and not falcate; sepals subequal, 4 mm. long, oblong-ovate, obtuse, densely pubescent with short appressed curved yellow hairs; petals bright yellow, about 13 mm. long, oblong or oblong-oblanceolate, obtuse, clawed, abundantly cinereous on the outer surface; anthers glabrous, nearly equal, the 3 lower slightly beaked; ovary strongly curved, densely covered with appressed yellowish hairs, Type in the U. 8. National Herbarium, no, 715333, collected in the vicinity of San Felix, eastern Chiriqui, Panama, altitude 120 meters or less, December, 1911, by H. Pittier (no. 5147). Closely related to Cassia undulata, but distinguished readily by the narrower stipules and bracts and by the broader, abruptly acuminate leaflets. In that species the stipules are more than 2 mm, wideand the bracts of the inflorescence oblong-lanceo- late to oval, while the leaflets are acute or abruptly acute. Cassia caudata Standley, sp. nov. Mature stems not seen, the young ones slender, terete, glabrous; rachis of the leaves terete, striate, 15 to 19 cm. long, the lower pair of leaflets borne 9 to 12 cm. above the base; stipules not seen; petiolar gland one, 2.5 mm. long, obtusely conic, borne between the lower pair of leaflets; petiolules stout, about 5 mm. long; leaflets 2 pairs, elliptic- oblong to ovate, 13 to 21 cm. long, 7 to 9 cm. wide, obtuse or rounded at the base and slightly unequal, acutish at the apex and abruptly contracted into an acute caudate tip 15 to 30 mm. long, thin, glabrous, bright green on the upper surface but not lustrous, decidedly paler beneath; leaflets of the lower pair shorter and broader than those of the upper; inflorescence of axillary several-flowered racemes or panicles about 7 cm. long, the branches appressed-puberulent with yellowish hairs; bracts linear- subulate, 3 mm. long; pedicels ascending, 15 to 20 mm. long; calyx lobes unequal, 4to 7 mm. long, obtuse, sparingly puberulent, green; petals bright yellow with dark veins, about 20 mm. long, 12 mm. wide or less, rounded at the apex, conspicuously clawed; anthers glabrous, slightly unequal, the 3 lower with short cylindric beaks; ovary terete, densely appressed-pubescent. STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 103 Type in the U.S. National Herbarium, no. 679652, collected in forests of the upper Mamont River, Province of Panama, Panama, altitude 150 to 400 meters, October, 1911, by H. Pittier (no. 4491). In Bentham’s revision of the genus this falls into the section Chamaefistula, series Bacillares.! It is related to Cassia bacillaris and C. inaequilatera, but from these and their allies it differs in having long-caudate leaflets. From each species it differs also in various minor respects. Cassia regia Standley, sp. nov. Tree; older branches blackish gray, slightly furrowed; young branches succulent, obtusely 5-angled, densely velvety-pubescent with short yellowish hairs; stipules linear-subulate, 2 mm. long, early deciduous; rachis of the leaf about 30 cm. long, the lowest pair of leaflets borne 2 cm. above its base, densely velvety-pubescent; petiolar glands none; leaflets about 20 pairs, approximate, narrowly oblong, 26 to 60 mm. long, 10 to 16 mm. wide, the lower and the uppermost shorter than those along the middle of the rachis, all acute, or the lower obtuse, apiculate, slightly unequal at the base and from truncate to acute, lustrous on the upper surface, con- spicuously veined, and furnished with numerous fine short stiff appressed hairs, beneath slightly paler, with sparse, short, spreading or appressed hairs, more promi- nently veined than on the upper surface; petiolules very thick, about 1 mm. long; inflorescence of numerous slender, solitary or clustered racemes 10 to 16 mm. long, borne on the old branches, densely velvety-pubescent with short hairs; bracts subu- late, small, deciduous before anthesis; pedicels ascending, 14 to 18 mm. long; sepals subequal, 7 mm. long, 4 mm. wide, oval-oblong, rounded at the apex, purple, with rather few minute appressed hairs; petals 12 mm. long, 8 mm. wide, orbicular-oval or broadly obovate, rounded at the apex, contracted at the base into a slender claw, pale yellow with conspicuous purple veins, glabrous; anthers 2 mm. long, sparingly pilose, the lobes smooth; ovary strongly curved, densely covered with appressed whitish hairs. Type in the U. S. National Herbarium, no. 677196, collected around El Parafso, Canal Zone, Panama, altitude 30 to 100 meters, January 24, 1911, by H. Pittier (no. 2532). Additional material is mounted on sheet 677197. Similar to Cassia grandis, but readily distinguished by its purple, sparingly pubes- cent sepals, and by its acute leaflets. The pubescence of the leaflets is much less abundant than in C. grandis, where it might be called tomentose. Specimens of the two species are very unlike in general appearance. Chamaecrista simplex Standley, sp. nov. Annual; stems erect, very slender, simple or with a few erect branches above, sparingly cinereous below, densely so above; leaves few and distant; stipules narrowly linear-lanceolate, 10 to 13 mm. long, attenuate, aristate-tipped, appressed, strongly nerved, ciliolate; rachis of the leaf 65 to 80 mm. long, bearing leaflets to within 3 or4 mm. of the base; petiolar gland sessile, cup-shaped, inserted just below the lowest pair of leaflets; leaflets 18 to 25 pairs, oblong or linear-oblong, 5 to 7 mm. long, about 1.5 mm. wide, acutish, mucronate, very oblique at the base, glabrous, ciliolate, rather thick and subcoriaceous, very prominently pinnate-nerved, the midvein excentric; flowers few in each cluster, on pedicels 3 mm. long or less, the bracts similar to the stipules but smaller and broader; sepals lanceolate, 5 mm. long, acute or acumi- nate, appressed, pubescent; petals about 6 mm. long; legumes erect, 35 to 40 mm. long, 4 mm. wide, obtuse, short-beaked, abundantly hirtellous. Type in the U. 8. National Herbarium, no. 679815, collected in the Sabana de Dormisolo, near Chepo, Province of Panama, Panama, at an altitude of 60 to 80 meters, October, 1911, by H. Pittier (no. 4655). 1Trans. Linn. Soc. Bot. 27: 519. 1871. 104. CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. Related, perhaps, to C’. patellaria, which it resembles in the sessile petiolar glands, but from which it differs conspicuously enough in the slender, simple or nearly simple stems with appressed pubescence, and in the small, subcoriaceous leaflets which are very oblique at the base.
