to 3 cm long ; stipules ovate, acuminate, 5 to 7 mm long. Panicles 
terminal, solitary, including the peduncle 11 to 14 cm in length, 
the peduncles 7 to 8 cm long; branches spreading, the lower 
ones up to 4 cm in length. Fruits subellipsoid, yellowish when 
fresh, black and somewhat shining and slightly rugose when dry, 
7 to 8 mm long, often with faint longitudinal lines but scarcely 
ridged or sulcate. Seeds plano-convex, the albumen very prom- 
inently ruminate.

(type), 29632 Ramos & Edaho, August 23, 1917, in forests near 
the summit, apparently at an altitude of about 1,000 meters. 
This species is in the group with Psychotria malayana Jack, 
and is probably as closely allied to P. luconiensis (Cham.) F.- 
Vill. as to any other species. It is readily distinguished by its 
larger leaves and long-peduncled panicles. 
PSYCHOTRIA MAGNIFOLIA sp. nov. 
Frutex 3 ad 4 m altus, glaber, vel inflorescentiis junior ibus 
obscure pubescens; ramulis compressis, 1 ad 1.5 cm diametro; 
foliis obovatis ad oblanceolatis, usque ad 55 cm longis, brevis- 
sime et obtuse acuminatis, deorsum angustatis, basi acutis vel 
cuneatis, breviter petiolatis, nervis utrinque circiter 25; stipulis 
membranaceis, ovatis, ad oblongo-ovatis, 3 ad 5 cm longis; in- 
florescentiis e basi 3-ramosis, ramis elongatis, usque ad 20 cm 
longis, partibus floriferis 3 ad 6 cm longis, floribus fasciculato- 
confertis, pedicellatis, circiter 8 mm longis. 
An erect, glabrous shrub, 3 to 4 m high, the branchlets stout, 
compressed, 1 to 1.5 cm in diameter, brownish. Leaves un- 
usually large for the genus, obovate to oblanceolate, 45 to 55 
cm long, 14 to 22 cm wide, subolivaceous and shining when dry, 
chartaceous, the apex broadly and shortly blunt-acuminate, 
below narrowed to the acute or cuneate base; lateral nerves 
about 25, prominent, curved, scarcely anastomosing, the reticula- 
tions lax, not prominent; petioles stout, 1.5 to 2.5 cm long; 
stipules membranaceous, nearly black when dry, ovate to oblong- 
ovate, acute, 3 to 5 cm long. Inflorescences 3-branched from 
th,e base, the central branch up to 20 cm in length, the lateral 
ones 10 to 15 cm long, flower-bearing only in the upper 3 to 6 
cm, the flowers here fascicled, crowded, forming a subcylindric 
partial inflorescence, or interruptedly glomerate; pedicels about 
6 mm long. Calyx turbinate, about 3 mm in diameter, the 
teeth 5, short. Corolla white, the tube 3 mm long, the lobes 
elliptic-ovate, acute, 5 mm long, the throat densely bearded.
