PSYCHOTRIA YUNGASENSIS, sp. n. (Eupsychotria) Stout, the branches 
erete, greenish, glabrous; stipules triangular-lanceolate to 
subulate, acute, 3 mm. long, one-half as broad; petioles 1-2 
cm. long, broad, divaricate, rigid, glabrous; leaves ovate to 
obovate, short-acuminate, acute, the base cuneate in variable 
degree, 1-3 dm. long by .5 to 2 dm. wide, dull or obscurely 
А the 
branches at about 40°, dichotomous, sparingly subulate-bracted 
at the base and upon a variable number of the branches, the 
latter flattened, channelled, and peculiarly pubescent along the 
upper side with stout, stiff hairs; flowers and fruits in the 
forks nearly or quite sessile, or adnate upon the branch at one 
side; buds regularly broadening to the truncate apex, where 
they are externally 5-saccate, pale; expanded flowers not seen; 
calyx constricted above the shining ovary, the limb broader, 2 
mm. long with short triangular, pubescent teeth; corolla strongly 
pubescent, slightly constricted above the base, the tube 4.5 
mm. long, bearing a circle of stiff hairs at the insertion of the 
stamens, the thickish lobes triangular-oblong, 2.5 mm. long, 
obtuse, each bearing a yellow protuberance at the tip, within; 
anthers clavate, black with white margins, 3 mm. long, one- 
sixth as broad at the rounded apex ; ovary 2-celled, black, the 
style stout, white, the two spreading stigmas black; fruit de- 
pressed and compressed-globose, 2-lobed, 4-5 mm. broad, each 
half with 3 principal sharp nerves. 
Yungas, 1890 (597 and 598).— Rusby 1865, determined as Р. 
cornigera, Benth. (?) This name appears not to have been pub- 
lished, and as there is doubt as to the identity, it is deemed best 
to publish a new name. The species seems nearest to P. pubigera, 
Muell. Arg.
