A. January 22, 1930 PRINTED IN THE UNITED STATES OF AMERICA BY FIELD MUSEUM PRESS v, 7' THE RUBIACEAE OF COLOMBIA PAUL C. STANDLEY The family Rubiaceae is an essentially tropical group. Although in America it is represented in the North Temperate Zone by a substantial number of species, these belong to only a few genera, and chiefly to Galium and Houstonia. The temperate Rubiaceae are mostly herbs, but those of the tropics are preponderantly shrubs, or occasionally large trees. The shrubs, particularly those belonging to the genera Palicourea and Psychotria, often form a conspicuous part of the undergrowth in the primeval forests, from- southern Mexico southward through Brazil, and along the Andes as far as southern Peru. In America it is in the vicinity of the equator, probably, that the family is most lavishly represented, but in Central America, especially in the mountains of Costa Rica and Panama, there exist many species. The genus Psychotria is well represented there, but it is worthy of note that the vast genus Palicourea, so profusely represented in the Andes, has but few Central American species. There has been published an adequate account of the Rubiaceae of only one South American country — Brazil. The text of Schumann, who treated the majority of the genera in Martius' FloraBrasiliensis, is a model of monographic work, and his exact and lucid account of the family must command the respect and admiration of all students of the group. Mueller's treatment of the Psychotrieae, the more difficult portion of the family, it must be admitted, is sadly inferior. In Colombia the Rubiaceae are exceptionally well represented, by a larger number of species, perhaps, than in any other American country except Brazil. This eminence may not be maintained when other regions have been explored more thoroughly, and I suspect that Colombia's present excellent showing in the Rubiaceae results largely from the extensive exploration carried on there in recent years. Nevertheless, consideration of the large number of Colombian species now known from a single collection leads to the presumption 4 FIELD MUSEUM OF NATURAL HISTORY— BOTANY, VOL. VII that many additions to the present species list may be expected as exploration progresses. Aside from their purely taxonomic interest the Colombian Rubiaceae demand attention because of their practical value. Some of the trees furnish wood of superior quality, and several yield drugs which are in demand abroad. Ipecac is the product of two or more low shrubs of the family, and from the Cinchonas, of romantic history, is obtained Peruvian bark, the source of quinine, one of nature's kindliest gifts to the world, and, above all, to dwellers in the malaria-infested tropics. For the natural product obtained from the bark of these Andean trees, now grown on so vast a scale in the distant East Indies, no satisfactory substitute has been found. One introduced plant of the same family has become of para- mount importance to Colombia. In the product of the Arabian coffee trees she finds one of the chief sources of wealth of her mountain departments. For the preparation of the present account of the Colombian Rubiaceae the writer has been exceptionally fortunate in being able to examine practically all the material existing in American herbaria. There have been studied the collections from the following insti- tutions, the letters in parenthesis being those used on the succeeding pages to indicate the location of the specimens cited : Field Museum of Natural History (F); United States National Herbarium (W); Gray Herbarium (G); Missouri Botanical Garden (M); New York Botanical Garden (Y ) ; Academy of Natural Sciences of Philadelphia (P). In addition, there have been received on loan more than 700 sheets from the Royal Botanic Gardens, Kew (K), and a smaller but interesting series from the Royal Museum of Stockholm (S). To the custodians of the herbaria from which specimens were lent the writer is deeply indebted. The collection received from Kew was of particular interest, as illustrating so characteristically the conditions existing with respect to South American material in most herbaria, in the case of families not monographed recently. Some of the specimens, if not from Colombia at least from other Andean countries, were collected more than a hundred years ago by classical collectors in these regions. Many of these relatively ancient specimens represent species described recently from collections made within the past thirty years, and others belong to species still undescribed. One wonders THE RUBIACEAE OF COLOMBIA 5 whether some of our own collections will lie in the herbarium an equally long time, to be studied by botanists whose grandfathers are not yet born. 1.

CINCHONA L. The species of Cinchona are the source of the drug quinine. Although several species of the genus occur in Colombia, the col- lection of the bark was never so important in that country as in Ecuador, Peru, and Bolivia. The genus has always been considered a difficult one. This results from the fact that the forms have been separated and named upon almost as slight characters as the Crataegus species of the THE RUBIACEAE OF COLOMBIA 11 United States. The trees were studied by men who were interested primarily in their products, which seem to vary greatly even within the species. Examination of a large amount of material in connection with a careful study of the extensive literature dealing with the taxonomy of the Cinchonas has convinced the writer that the actual number of recognizable species, according to our usual species standards, is a small one, and that most of the names must be reduced to synonymy. Cinchona barbacoensis Karst. in Koch & Fint. Wochenschr. 2: 31. 1859; Fl. Columb. 1: 47. pi 23. 1859.

A tree 4-9 m. high, the branchlets appressed-pilose; stipules lanceolate, acute, pilosulous; leaves short-petiolate, oblong-elliptic to oblong-oblanceolate, 10-18 cm. long, 6-7 cm. wide, acute, attenuate to the base, glabrate above, beneath pilose, especially on the nerves, with short stiff subappressed hairs; inflorescence sessile, large, broad, the flowers congested; hypanthium sericeous; calyx glabrate, the teeth short, triangular, acute; corolla sericeous, white or pink, 1 cm. long, the 5 lobes lanceolate, obtuse, shorter than the tube; capsule linear, 5-9 cm. long, 3-5 mm. broad, glabrate. Cinchona barbacoensis is remarkable because of the fact that it grows at a lower altitude than any other species of the genus. It is well marked by the long and very slender capsules, which often are curved. Cinchona Henleana Karst. in Koch & Fint. Wochenschr. 2: 31. 1859; Fl. Columb. 1: 55. pi 27. 1859.

"Quina amarilla," "quina terciopelo," "quina calisaya." The species as here treated is a highly variable one as regards shape and pubescence of the leaves, form of calyx lobes, and size of corolla. It seems impossible, however, at least with the information now available, to divide it into species or varieties which can be recognized with any considerable degree of accuracy. The forms of C. pubescens are the chief source of quinine. They vary greatly as to their quinine content. Cinchona rosulenta Howard ex Wedd. Ann. Sci. Nat. V. 12: 66. 1869.

H. Smith 414 (F, W, P). Widely distributed in tropical America. A medium-sized tree; leaves ovate to rounded-oval, abruptly acuminate, 5-12 cm. long, nearly glabrous; flowers small, white, in terminal corymbose panicles; calyces partly with one large foliaceous petioled white lobe; fruit a cylindric capsule 6-10 mm. long. In Panama the tree is called "alazano," "harino," "salamo," "madrono," and "guayabo alazano." The wood is heavy, strong, and very fine-grained. It is employed in Central America for making combs, and burned for charcoal. The tree is an exceptionally beau- tiful one when in flower, because of the abundance of long-persisting, white or cream-colored calyx lobes, which give it the appearance of a huge bouquet. 12.

It is doubtful whether the other species listed here are distinct from C. grandiflora. I have not seen type material of them, and the descriptions do not mention any characters which seem very impor- tant. The corolla evidently exhibits great variation in length. Cinchona grandiflora was described from Peru, but Ruiz and Pavon cite also specimens from Colombia, collected near Quebrada Larga by Sebastian Jose" Lopez Ruiz. They give the vernacular names as "mestiza," "azuceno," "capecape," "capecito," and "cape negro." Lehmann reports the vernacular name as "narciso." Cosmibuena macrocarpa (Benth.) Klotzsch ex Walp.

Toro 749, a fruiting specimen, differs from the other collections in its smaller leaves, laxer inflorescence, and longer calyx lobes, but it is probably only a variant from the typical form. R. euryphylla is easily recognized by the abundant, soft or somewhat rough pubes- cence of the leaves, and by the complete absence of tomentum except sometimes on the corolla.

The corolla is described as "red," "pale carmine," and "tube pink, lobes white, pink-tinged." The specimens cited are variable in size of corolla and in leaf pubescence. It may well be that they represent more than a single species, but the material at hand is not sufficiently extensive to enable one to determine the importance of the variations. Either all the material represents one species, or else it should be separated into three to five, and the propriety of such a separation is very doubtful under present conditions. R. inconstans agrees in most details with the description of R. orthoneura Schum. & Krause, but in that the flowers are said to be pentamerous. Rondeletia orthoneura Schum. & Krause, Bot. Jahrb. Engler 40: 314. 1908. Type reported as from Colombia, Warscewicz 622. Stipules ovate-oblong, 6-8 mm. long; petioles 3-6 mm. long; leaf blades elliptic or oblong-elliptic, 6-14 cm. long, acuminate, at the base acutish or rounded, villous-tomentose when young, in age arachnoid-pilose; flowers 5-parted, the panicle long-pedunculate; calyx lobes linear, 2 mm. long, acute; corolla tube 12-15 mm. long, tomentose. It is quite possible that the type of this species is from Panama rather than Colombia.

Kew., type). Coteje, Rio Timbiqui, November, 1898, Lehmann B.T.519 (K). The true position of this plant is quite uncertain. Evidently it is closely related to Sabicea umbrosa Wernh., but both these species are so unlike other members of the genus Sabicea that I was at first inclined to make them the basis of a new genus. After learning that one of them had been referred to Sabicea without question by Wernham, I decided to leave the two plants temporarily in that genus, until better material of them may be obtained. The leaves in both these species seem to me to be alternate, with a stipule opposite each leaf. Wernham, however, illustrates the type spec- imen of S. umbrosa with opposite leaves. I have not seen the type, but a second specimen of the same species which I have seen, prob- ably a part of the type collection, seems to me to have alternate rather than opposite leaves, a condition almost unknown in the family Rubiaceae.

The species is widely distributed in tropical America. A glabrous tree, sometimes 6 m. high; leaves mostly oval or oblong and 8-20 cm. long, acute or short-acuminate, coriaceous; flowers white, in dense terminal cymes; corolla tube slender, 13-18 cm. long; fruit globose, 4-5 cm. in diameter, yellow, edible, full of large seeds. "Narciso de monte" (Turdie); "cachaco" (Villavicencio); "chu- rumbelo" (Cartagena). Called in Panama "borajo," "boca vieja," "fruta de mono," "huevo de mono," and "fruta de murcie*lago." The tree is a very showy one in flower. P. platysiphonia is distin- guishable only by the broad corolla tube, and I suspect that this had its origin only in heavy pressure during the drying of the speci- mens. Killip & Hazen 8794 is a fruiting specimen, remarkable for its broad rounded leaves. Flowering material may show it to be a distinct species.

Called "jagua" in Panama; "caruto" in Venezuela; "bi," "bicito," and "tutumillo" in Bolivia; "jenipapa," "jenipabo," in Brazil; "tapuripa" in Surinam. This tree and the preceding one are common and widely dispersed in tropical America. Their wood is strong and resistant, flexible, whitish, tinged with gray. It is used for many purposes. The bark is rich in tannin. The scant pulp of the fruit is edible, but not very palatable, and its juice is sometimes fermented to produce an intoxicating beverage. Upon cloth the juice produces a permanent brownish or blackish stain, and it was much used by the Indians for dyeing. It was employed commonly, and is still utilized in some regions, for painting the body, giving almost the same general effect as tattooing. 47. DUROIA L. f. Duroia genipoides Hook. f. in B. & H. Gen.

The Holton collection, which is in fruit, although having much smaller leaves than the type, is almost certainly conspecific. The fruit, still immature, is globose, 6 mm. in diameter, and obtusely tuberculate. In the form of the corolla F. Lehmannii suggests F. occidentalis, but in that the leaves are thinner and less conspicuously veined and the calyx is dentate.

Anti- oquia, alt. 2,100 m., December 25, 1879, Kalbreyer (Herb. Kew., type). This is very unlike any of the other Farameas of western South America, being especially well marked by the very small narrow leaves, slender habit, and solitary flowers. The form of the calyx, also, is unusual, but the characters of the plant as a whole seem to agree well enough with those of other species of the genus Faramea. Faramea Purdieana Benth.

PSYCHOTRIA L. Psychotria is the largest genus of the family Rubiaceae, and almost pan-tropic in its distribution. In Colombia it is represented by about 75 species, a number which will increase with later explo- ration, since many species of the genus are known to be local in distribution. The genus is a difficult one. The species often seem to be separated only by slight characters, yet as material accumulates, it usually strengthens the species and emphasizes the importance of the distinguishing characters, despite the apparent triviality of the latter. This genus exhibits a far greater amount of variation than its close relative, Palicourea. While the inflorescence of Palicourea is constant as to form, that of Psychotria follows no special pattern, but is susceptible of almost endless variety. The stipules, likewise, which are so uniform in general appearance in Palicourea, are greatly diversified in Psychotria. Mueller, in his treatment of Psychotria and allied genera in Martius' Flora Brasiliensis, employed a generic arrangement which has been adopted by few subsequent authors. He united with Psychotria the genera Palicourea, Geophila, and Cephaelis, but kept as distinct Mapouria, here merged in Psychotria. It must be admitted by all who know these groups that the genera are difficult of separation. There are no sharp lines of demar- cation between Psychotria and Cephaelis, or between Psychotria and Palicourea. Often it is a matter of personal judgment, rather intuition than a result of conviction based upon examination of structural details, which determines the allocation of a given plant 84 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. VII in one or the other group. But the groups are all so large, and for the most part so easy of recognition, at least after considerable experience, that it seems advisable to recognize them. Mapouria possesses good claims for recognition, but it and Psychotria can be distinguished definitely only with mature fruit. Since in many species the fruit is unknown, it is not practical at the present time to accord generic rank to Mapouria. Psychotria alba R. & P. Fl. Peruv. 2: 58. pi. 205, f. a. 1799.

P. floribunda HBK. (Nov. Gen. & Sp. 3: 359. 1820) must be closely related, if not a synonym of this species. The type locality is given doubtfully as Turbaco. Jacquin's brief description and his plate (Sel. Stirp. Amer. pi. 174, f 22) are far from satisfactory for the identification of his species, which is probably the same as either P. foveolata or P. alba R. & P. Since there is at hand a specimen from Cartagena referable to P. foveolata, and none referable to P. alba, I have assumed that the Jacquin plant is conspecific with the former.

PALICOUREA Aubl. Palicourea is an American genus which reaches its greatest development in the South American Andes. It extends northward to central Mexico, and ranges through the West Indies, but with only a small number of representatives. In Central America the species are very few until Costa Rica is reached. In that country, whose flora shows such striking affinities with that of Ecuador, the number of Palicoureas is a substantial one, and the shrubs form a conspicu- ous part of the undergrowth in the cold wet mountain forests. Psychotria is represented in Mexico by a respectable number of species, and in the West Indies by a very large number. THE RUBIACEAE OF COLOMBIA 117 Most of the members of both genera are quite without economic importance. Although the Psychotrias, except sometimes in fruit, are inconspicuous, with chiefly whitish or greenish flowers, the Palicoureas often are strikingly beautiful, with blossoms in varying shades of yellow, orange, red, blue and purple. The stipules in Palicourea are always, probably, persistent, green, and united into a sheath which terminates in four broad or narrow lobes. The leaves are much more uniform than in Psychotria. The inflorescence is terminal and generally thyrsiform, although not invariably so. The corolla is usually longer and narrower than in Psychotria, and nearly always has an evident "bulge" at the base. When dry, the inflorescence almost always has a yellowish or reddish tinge, which is rare in Psychotria. The corollas often change color in drying, especially if they are blue or purple. About 70 species of Palicourea are known at present from Colombia. Probably no other country can produce so large a number, unless it be Ecuador. The Ecuadorian flora is still so little known that one can not make estimates regarding its composition with any high degree of safety. Palicourea abbreviata Rusby, Descr. N. Sp. S. Amer.

The sheet of Pennell 2394 in the herbarium of the New York Botanical Garden bears an annotation to the effect that it was compared at Kew in September, 1920, and found to be P. popaya- nensis Benth., equaling " Hartweg 1055." The type of P. popayanen- sis, however, is Hartweg 1058, and No. 1055 is listed (PI. Hartw. 192. 1845) as Gonzaka pulveruknta H. & B. The plant here described does not agree in various details with Bentham's description, and I can not believe that P. ionantha belongs to that species. The leaves of P. popayanensis are described as appreciably larger, and the corolla as orange-colored.

This species does not appear to be closely related to any of those described previously from Colombia. It is distinguished particularly by the abundant pubescence, the large calyx of dis- tinctive form, and the very broad corolla clothed with long shaggy pubescence. Kalbreyer describes the plant as a shrub of 1.5-2 m., with light blue inflorescence and blue corolla.

Although referred by Schumann to the genus Rudgea, I see no reason for excluding this plant from Palicourea. The long appendages of the corolla lobes are very unusual in Palicourea, it is true, but they would be exceptional also in Rudgea, and the stipules are quite unlike those found in the latter genus.

A shrub or small tree, nearly glabrous, the branches quadrangular; stipule sheath 5-10 mm. long, truncate, biaristate, the aristae subu- late, about as long as the sheath; leaves short-petiolate, thick and firm, elliptic or oblong-elliptic, 12-25 cm. long, 5-11 cm. wide, abruptly short-acuminate, acute at the base, many-veined, hirsute- pilosulpus beneath along the costa; panicle pedunculate or sessile, thyrsoid, up to 30 cm. long, narrow, the short branches divaricate, glabrous; flowers usually long-pedicellate; calyx lobes ovate, obtuse; corolla glabrous, 7 mm. long; fruit 5 mm. long. The corolla is variously described as "pale yellow," "light blue," and "blue," but all the specimens appear to be conspecific. The flower colors reported for some of the species of Palicourea are very confusing and inconsistent, and it seems certain that in many cases they have been noted carelessly, perhaps from memory, or by persons who had no definite idea of the definition of color terms, a class to which many of our botanists seem to belong. The size of the plant, likewise, seems to have been reported too often from memory alone. THE RUBIACEAE OF COLOMBIA 147 Palicourea popayanensis Benth. PI. Hartw. 193. 1845.

The Pennell specimen, however, does not agree with the original description of P. popayanensis, while the specimens here cited do agree with it in most details. Palicourea populifolia Rusby, Descr.
