at all sulcate, the seeds plano-convex, ruminate, not at all sulcate 
or ridged on the back. 
Luzon, Province of Cagayan, Abulug River, Bur. Sci. H582 (type), 
13928 Ramos, For. Bur. 19638 Curran, January, 1912, in forests. 
A species manifestly allied to Psychotria tayabensis Elm., differing 
especially in its larger, more numerously nerved leaves. 
PSYCHOTRIA ALVAREZII sp. nov. 
Species P. bataanensi Elm. valde affinis, differt foliis majo- 
ribus, usque ad 15 cm longis, basi late rotundato-cordatis, nervis 
utrinque circiter 25, fructibus obovoideis, conspicue 8-alatis. 
A shrub or small tree, somewhat pubescent, or nearly glabrous, 
the leaves reddish-brown when dry. Branches terete, dark- 
grayish. Leaves oblong to oblong-ovate, coriaceous, 12 to 15 
cm long, 4 to 7 cm wide, somewhat narrowed to the rather 
broadly rounded-cordate base, more narrowed towards the obtuse 
or rounded apex, the upper surface smooth, glabrous, shining, 
the lower often slightly pubescent, reddish-brown, the lateral 
nerves very prominent, 18 to 25 or more on each side of the 
midrib, slightly curved, anastomosing, the reticulations distinct; 
petioles 1 to 2 cm long, usually somewhat pubescent; stipules 
early deciduous, not seen. Flowers not seen. Infrutescence ter- 
minal, simple and unbranched or with three branches from the 
base, the branches or peduncles 1.5 cm long or less, the fruits 
capitately arranged, few to many, forming subglobose heads, the 
individual fruits obovoid, shortly pedicelled, about 7 mm long, 
longitudinally 8-winged, the wing-like ridges rather thin, 1 to 
1.5 mm wide. Seeds plano-convex, ruminate, not longitudinally 
ridged or sulcate on the back. 
Luzon, Province of Nueva Ecija, For. Bur. 22189 Alvarez, December, 
1910. 
A species manifestly allied to Psychotria bataanensis Elmer, but with 
larger, more numerously nerved, differently shaped leaves, and its fruits 
with the longitudinal ridges developed into 8 narrow wings. In Psychotria 
bataanensis the fruits are sulcate or ridged, but in no degree approach 
the fruits of the present species in this respect. 
PSYCHOTRIA RIZALENSIS sp. nov. 
Species P. bataanensi Elm. valde affinis et similis, differt foliis 
basi acutis vel subrotundatis, vix anguste cordatulis. 
A shrub or small tree, the branchlets, petioles, younger leaves 
on the midrib and lateral nerves beneath pubescent with 
dark-brown hairs, the branches terete, brownish, glabrous. 
Leaves oblong to oblong-elliptic, coriaceous, 8 to 10 cm long, 2 
to 4 cm wide, the upper surface smooth and shining, quite gla- 
brous, the lower somewhat paler, the lateral nerves very prom-
