STANDLEY—TROPICAL AMERICAN PHANEROGAMS, 181 
Psychotria albonervia Standley, sp. nov. 
Shrub; young branches stout, obscurely angled, green, glabrous; stipules distinct, 
12 to 17 mm. long, 6 to 8 mm, wide, coriaceous, green tinged with purple, conspicu- 
ously parallel-veined, soon deciduous, each 2-lobed to the middle, the lobes narrowly 
lanceolate, acuminate, ciliolate; petioles 5 to 15 mm. long, stout, leaf blades narrowly 
oblong-oval to elliptic-oblong or rarely obovate, 10 to 16 cm. long, 2.5 to 6 cm. wide, 
abruptly acuminate or attenuate, obtuse and somewhat decurrent to cuneate at the 
base, coriaceous, bright green, shining, and glabrous on the upper surface, beneath 
paler, glabrous except along the veins, these very conspicuous, broad, white, minutely 
ciliolate, the lateral ones 17 to 25 on each side, parallel, anastomosing to form an 
irregular marginal vein; peduncles terminal, 3 to 5.5 cm. long, glabrous, the inflo- 
rescence thyrsoid-paniculate, 3 to 6 cm. long, 3 to 5.5 cm. wide, the main branches 
verticillate, divaricate, stout, sparsely pubescent with short spreading white hairs; 
flowers clustered at the ends of the peduncles, sessile or subsessile; bracts whitish, 
6 to 8 mm. long, lanceolate to oblong or oval, obtuse or acutish, ciliolate, prominently 
veined; calyx very short, the teeth triangular, acute; corolla 8 to 10 mm. long, white, 
glabrous outside, villous within near the base, the tube 1.5 to 2 mm. in diameter, 
the lobes oblong to broadly ovate, half as long as the tube, obtuse or acutish; filaments 
elongate, the anthers exserted; fruit not seen. 
Type in the U. 8. National Herbarium, no. 47282, collected in the vicinity of 
Chagres, Panama, in February or March, 1850, by August Fendler (no. 62). Another 
specimen of the same collection is in the Gray Herbarium. 
Also collected in the Sabana de Marcelito near El Vigfa, Panama, on edge of forest, 
January 12, 1911 (Pattier 2379). 
This finds its nearest ally in Psychotria arcuata Benth.,’ described from British 
Guiana, but occurring also in Grenada, Tobago, and Trinidad, according to Urban,? 
and in Brazil, according to Schumann.’ Schumann considers P. arcuata a synonym 
of P. inundata Benth., published at the same time, but specimens of the type collec- 
tions in the U. 8. National Herbarium appear to represent distinct species. Psychotria 
arcuata is distinguished from the Panamanian species here proposed as new by the 
very different persistent stipules and the thinner, smaller leaves. 
Psychotria magna Standley, sp. nov. 
A shrub 3 meters high; young branches stout, obtusely angled, minutely puberulent 
or glabrate; stipules not seen, evidently soon deciduous; petioles stout, 2 to 4 cm. 
long, glabrous; leaf blades oval or elliptic-oval, 18 to 25 cm. long, 8 to 11.5 cm. wide, 
abruptly caudate or attenuate from an obtuse apex, the tip narrowly triangular, 2 to 
3 cm. long, obtuse or broadly cuneate at the base, herbaceous, drying dark brown, 
glabrous, or very minutely puberulent on the veins beneath, the lateral veins promi- 
nent, 17 to 20 on each side, parallel, scarcely anastomosing at the margin; inflorescence 
terminal, cymose-paniculate, sessile, about 10 cm. long and broad, much branched, 
the branches spreading, very minutely puberulent; flowers sessile, capitate at the ends 
of the peduncles; no bracts seen; calyx and ovary together 1.5 mm. long, the limb 
of the calyx undulate, ciliolate; corolla yellowish white, 3 to 4 mm. long, glabrous 
outside, densely white-villous within, the tube thick, the lobes as long as the tube, 
oblong or ovate-oblong, obtuse or acutish, spreading: filaments stout, elongate, the 
anthers exserted; fruit not seen. 
Type in the U. 8. National Herbarium, no. 679188, collected in forests, Loma de la 
Gloria, near Faté, Province of Colén, Panama, at an altitude of 10 to 100 meters, 
August, 1911, by H. Pittier (no. 4092).
