Ng Chi Leng, McClure 8702, December 20, 1921. On forested 
slopes, altitude 700 meters. 
A form first identified by me with Antidesma apiculatum 
Hemsl. but differing from that species in very numerous char- 
acters, notably in its smaller, fewer-nerved leaves which are 
pilose on the nerves beneath, shorter pedicels, much shorter 
racemes, and differently shaped fruits. 
MALLOTUS MACLUREI sp. nov. § Axenfeldia. 
Frutex circiter 1.5 cm altus, ramis teretibus, glabris, ramulis 
obscure puberulis; foliis suboppositis, in paribus inaequimagnis, 
haud granulari-glandulosis, chartaceis, in siccitate pallidis, supra 
glabris, subtus ad costa leviter pilosis, subcaudato-acuminatis, 
deorsum leviter angustatis, basi truncato-rotundatis vel subcor- 
datis, nervis utrinque 7 vel 8, perspicuis, irregulariter dentatis, 
foliis majoribus usque ad 13 cm longis et 4.5 cm latis, minor- 
ibus 6 cm longis et 2 cm latis; petiolo foliis majoribus 1 ad 2 
cm longo; infructescentiis simplex, racemosis, circiter 6 cm 
longis, capsulis 10 ad 12 mm diametro, granulari-glandulosis, 
echinatis, echinis sparsis, submollis, 2 ad 3 mm longis, curva- 
tis, glabris. 
Ng Chi Leng, McClure 8558, December 20, 1921. In forested 
ravines, altitude 600 meters. 
This species is allied to Mallotus esquirolii Lév. from which 
it differs in its smaller leaves which are not strictly opposite, 
and which are truncate-rounded or even slightly cordate at the 
base. The capsules are not densely echinate, the spines being 
distinctly scattered.
