equal and much longer than fruit, or two segments growing out into long 
wings. So far as known, the cells of the cotyledons filled with starch. 
“Pith of internode with 10 to 20 small peripheral resin-canals. 
Petiole; peripheral bundle-system with 3 to 10 resin-canals, the central 
with a few resin-canals or without them.” 
About 45 species known, with probably 5 species in the Philippines. 
Quite probably, some of the very variable material which is lumped 
under V. mangachapoi may be referable to other species when more 
complete specimens are secured.

This species is very incompletely understood ; but, I have followed the 
interpretation accepted by Brandis. 
A moderate-sized tree of the hill forests. Not gregarious. Bark light- 
grayish and rather smooth. Wood hard and heavy, brownish, fine-grained, 
resembling yacal but finer- and straighter-grained. ‘Glabrous, excepting 
inflorescence and young shoots, which are clothed with stellate tomentum. 
Stipules small, caducous. Leaves pale on both sides, coriaceous, lanceo- 
late; blade 7.5 to 12.5 cm long; petiole 1 cm long. Secondary nerves 
7 to 9 pairs; tertiary reticulate. Flowers 1 cm long, on. pedicels nearly 
as long as the calyx, in racemes which are not unilateral, these arranged 
in terminal and axillary racemose panicles. Pseudoterminal flowers 
frequent between the main axis and a branch of panicle. Calyx-segments
