its elongate, slender, staminate inflorescence, which is 10 to 15 cm in 
length, and its somewhat rugose capsules. 
Alchomea sicca (Blanco) Merr. is glabrous or nearly so, and its dense 
male spikes are usually less than 2 cm long, rarely 4 to 5 cm in length. 
In addition to the material previously referred here, it is represented 
by Merrill ^100, Phil. PL 988 Merrill, and Didrichsen 3146, 3170, all from 
Manila.

This widely distributed species is represented in our herbarium by about 
30 specimens from the Philippines, for the most part determined and dis- 
tributed as Alchomea javensis Muell.-Arg. It extends from northern 
Luzon to southern Mindanao. It is represented also by Ridley 107, from 
Christmas Island (south of Java), and by specimens from Java collected 
by Boerlage. India, through Malaya to the Admiralty Islands. 
ANTIDESMA Burmann. 
ANTIDESMA CRASSIFOLIUM (Elm.) comb. nov. 
Sapium crassifolium Elm. Leafl. Philip. Bot. 2 (1908) 485. 
Negros, Cuernos Mountains, Elmer 10312, June, 1908, type number. 
This species is an Antidesma in all respects, and is apparently very 
closely allied to Antidesma bunius Spreng. It differs from that species 
in its more pubescent spikes, and thicker, fewer-nerved leaves. Mature 
leaves are very thickly coriaceous, but immature ones, distributed under 
the type number, are membranaceous or chartaceous. Pax and K. Hoff- 
mann * state that the species does not belong in the Euphorbiaceae, as 
the specimen examined by them appeared to have perfect flowers. All 
the flowers on my specimens are staminate, and are the characteristic 
ones of Antidesma; in poor material the rather prominent pistillode might 
have been mistaken for a fertile ovary. 
ANTIDESMA MINDANAENSE sp. nov. 
Frutex 3 ad 4 m altus ramulis inflorescentiisque exceptis 
glaber; foliis oblongis vel anguste oblongo-ovatis, acuminatis, 
usque ad 20 cm longis, breviter petiolatis, nervis utrinque 
circiter 7, prominentibus, anastomosantibus ; stipulis oblongo- 
lanceolatis, acuminatis, 8 ad 10 mm longis; racemis termina- 
libus, pubescentibus, 5 ad 15 cm longis, solitariis; floribus 5 
4-meris, sepalis ovatis, acutis, circiter 4 mm longis; fructibus 
ovoideis, purpureis, in siccitate rugosis, 4 ad 5 mm longis. 
A shrub or small tree 3 to 4 m in height. Branches slender, 
terete, grayish, glabrous, the younger ones somewhat pubescent.
