A scandent shrub, the branchlets and panicles rather promi- 
nently hirsute with short, stiff, dark, spreading hairs. Branches 
terete, reddish-brown, glabrous, usually with rather numerous 
roots, the branchlets slender, the younger ones rather densely 
hirsute. Leaves numerous, rather crowded on the branchlets, 
oblong-ovate, subcoriaceous, 2 to 2.5 cm long, 8 to 12 mm wide, 
dark-brown when dry, rather brittle, glabrous, or with few 
scattered hairs on the lower surface, acuminate, base subacute, 
margins usually recurved; lateral nerves 4 or 5 on each side of 
the midrib, prominent on the lower surface, the reticulations 
subobsolete; petioles about 1 mm long, more or less hirsute. 
Panicles terminal, pyramidal, about 4 cm long and wide, sessile 
or nearly so, the branches few, spreading. Fruits ovoid or 
narrowly ovoid, glabrous, about 4.5 mm long, dark-brown and 
sulcate when dry, somewhat urceolate. Seeds flat on the inner 
surface, prominently longitudinally 3-sulcate or 3-keeled on the 
back, albumen not at all ruminate.

The alliance of this species is with Psychotria elliptifolia Elm., from 
which it is at once distinguished by its much more prominently nerved 
leaves and its pubescent branchlets. 
PSYCHOTRIA BALABACENSIS sp. nov. 
Frutex erectus, circiter 4 m altus, glaber; foliis membrana- 
ceis, ellipticis ad oblongo-ellipticis, usque ad 14 cm longis, in 
siccitate pallidis, nitidis, apice abrupte breviter obtuseque acu- 
minatis, basi decurrento-acuminatis, nervis lateralibus 7 vel 8, 
tenuibus; infructescentiis terminalibus, brevissime pedunculatis, 
laxis; fructibus circiter 9 mm longis, globoso-ovoideis ad obov- 
oideis, laevis, pyrenis plano-convexis, laevis, albumine aequabile. 
An erect glabrous shrub about 4 m high. Branches terete, 
reddish-brown, the branchlets slender, pale-greenish. Leaves 
membranaceous, pale and shining when dry, elliptic to oblong- 
elliptic, 9 to 14 cm long, 4.7 to 7 cm wide, apex rather abruptly, 
shortly, and broadly acuminate, the base somewhat decurrent- 
acuminate; lateral nerves 7 or 8 on each side of the midrib, 
slender, spreading, distant, somewhat curved, anastomosing, the 
reticulations very lax, obscure; petioles 1.5 to 2 cm long; stipules 
very broad, subacute, pale, about 3 mm long. Infructescence 
terminal, lax, 4 to 6 cm long, the peduncles 5 mm long or less, 
the branches few, elongated, slender, pale. Fruits about 9 mm
