basi longe angustatis, chartaceis vel subcoriaceis, nitidis, nervis 
utrinque circiter 20, subtus valde prominentibus; paniculis ter- 
minalibus, longe pedunculatis, multifloris, ramis primariis secun- 
dariisque subumbellatim dispositis; floribus circiter 6 mm longis. 
A small tree, 3 m high according to the collector, glabrous 
or nearly so. Branches terete, light grayish-brown, the ultimate 
ones about 4 mm in diameter. Leaves oblong to broadly oblong- 
oblanceolate, 15 to 20 cm long, 6 to 7.5 em wide, chartaceous to 
subcoriaceous, the apex acute or obscurely acuminate, base grad- 
ually narrowed and acute or cuneate, the upper surface brown- 
ish-olivaceous when dry, somewhat shining, the lower much 
paler, shining, sometimes slightly pubescent along the midrib; 
lateral nerves 20 on each side of the midrib, very prominent 
on the lower surface, curved, anastomosing very close to the 
margin, the reticulations slender, subparallel, lax; petioles 2 
to 3 cm long; stipules not seen, very early deciduous. Inflor- 
escence terminal, up to 18 cm in length, usually about 3 peduncles 
from each branchlet, the peduncles 8 to 11 cm long, black when 
dry, each bearing 5 umbellately disposed primary branches 1.5 
to 3.5 cm in length, the tertiary and the ultimate branchlets 
also umbellately arranged. Flowers white, usually about 3 on 
each ultimate branchlet, their pedicels 1 mm long or less, the 
whole inflorescence black when dry. Calyx cup-shaped, about 
2 mm long, truncate or irregularly toothed. Corolla-tube cyl- 
indric, villous inside, 4 mm long, the lobes 4, oblong, obtuse, 
2 mm long, thickened at the apex inside; anthers 1 mm long. 
Luzon, Subprovince of Bontoc, Bauco, Vanoverbergh 2610, March 9, 
1913, along streams, altitude about 1,500 meters. 
A species in the group with Psychotria banahaensis Elm., but not 
closely allied to that species. It is characterized by its long-peduncled, 
many-flowered inflorescence with its umbellately arranged branches and 
branchlets, and its many-nerved, comparatively large leaves. 
PSYCHOTRIA VANOVERBERGHII sp. nov. 
Arbor parva, glabra, circiter 4 m alta, ramis teretibus; foliis 
oblongo-ellipticis ad late oblongo-lanceolatis, coriaceis, utrinque 
-angustatis, usque ad 8 cm longis, obscure obtuse acuminatis, basi 
acutis, in siccitate nitidis, virdis vel brunneis, nervis utrinque 
circiter 15, tenuibus, vix prominentibus; inflorescentiis terminal- 
ibus, usque ad 4 cm longis, paucifloris; floribus pedicellatis, 
circiter 6 mm longis. 
A small tree, glabrous throughout. Branches slender, terete,
