petio es 1 to 1.5 cm long, glabrous or nearly so. Panicles ter- 
minal, pyramidal, branched from the base or peduncled 7 to 9 
cm long, many-flowered, the rachis and branches glabrous or 
nearly so, the branches few. Male flowers yellowish, somewhat 
crowded at the ends of the branchlets. 5-merous, their pedicels 
up to 2 mm long. Calyx cup-shaped, 2 mm in diameter, obscurely 
5-toothed, outside rather densely pale-lepidote. Petals very 
broadly ovate to ovate-orbicular, about 1.3 mm long, rounded 
base with a very short, broad claw. Stamens 10, short. ■ Ovary 
entirely wanting.

This species, as here interpreted, is the most common and widely dis- 
tributed one in the Philippines, extending from northern Luzon to Basilan ; 
It has also been reported from northeastern Celebes by Reorders. The 
type is Cuming 999 from the Province of Pangasinan, Luzon, of which 
there is a mere fragment in the herbarium of the Bureau of Science. In 
describing the species Vidal also referred here Nos. SiS, 6U, and 1387 of 
his own collection, the first two from Rizal Province, the last from Lepanto 
bubprovmce. Among the specimens referred here some are distinctly 
3-nerved, agreeing with the type number, Cuming 999, while others are 
as distinctly 3-plinerved, agreeing with the specimens of Vidal's own collec- 
tion cited by him; it should be noted that in the original description of 
the species that it is described as having 3-plinerved leaves. From an 
examination of our large series of specimens it is evident that the 3-nerved 
and 3-plinerved forms referred here represent but a single species in spite 
of the differences in the extreme cases as to the disposition of the nerves. 
Ihe vegetative characters otherwise, the indumentum generally, the in- 
florescences, and the flowers are fairly uniform in all the specimens. In
