stipules ovate, acuminate, about 4 mm long, deciduous, the 
stipular scar on the branchlets usually castaneous-villous. In- 
fructescences terminal, solitary, less than 1 cm long without 
the fruits, 3-branched, the branches short, each bearing at its 
tip from 1 to 5 shortly pedicelled, oblong-ellipsoid, 7 mm long 
fruits. Bracteoles ovate-lanceolate, acuminate, about 3 mm long. 
Fruits dark-purple or black when fresh, castaneous when dry, 
longitudinally sulcate, their pedicels 1 mm long or less. Py- 
renes plano-convex, prominently 4-keeled, the albumen uniform.

This species is well characterized by its small size, in size 
resembling Psychotria repens Elm. It differs radically from 
Elmer’s species not only in its habit, but also in being entirely 
glabrous except for its pubescent stipular scars. 
PSYCHOTRIA SCABERULA sp. nov. 
Frutex erectus, inflorescentiis leviter hirsutis vel pubescens, 
foliis subtus scabridis; foliis chartaceis, oblongo-ellipticis ad 
elliptico-obovatis, olivaceis, 16 ad 20 cm longis, breviter acu- 
minatis, basi decurrentibus, nervis utrinque circiter 15, perspi- 
cuis ; inflorescentiiis circiter 3 cm longis, ramis primariis paucis, 
usque ad 2 cm longis, floribus sessilibus, in capitulis globosis 
circiter 1.5 cm diametro dispositis, calycis usque ad 8 mm longis. 
An erect shrub or small tree, the inflorescences slightly hir- 
sute or pubescent with short hairs, the leaves distinctly scabrid 
on the lower surface by scattered, short, stiff, projecting hairs. 
Leaves chartaceous, oblong-elliptic to elliptic-obovate, dark 
olivaceous when dry, 16 to 20 cm long, 7.5 to 11 cm wide, the 
apex shortly acuminate, the base somewhat decurrent, the upper 
surface smooth, glabrous, the lower surface distinctly hirsute 
with short hairs on the midrib and nerves and with short, pro- 
jecting, stiff hairs from thickened bases on the epidermis; 
lateral nerves about 15 on each side of the midrib, distinct, 
the reticulations lax, not prominent; petioles about 4 cm long. 
Inflorescences terminal, 3 cm long or less, sparingly branched, 
the primary branches 2 cm long or less, somewhat hirsute, each 
bearing a rather dense, globose head of sessile flowers, about 
1.5 cm in diameter. The calyces up to 8 mm long, the limb 
distinctly produced above the ovary.
