PHILIPPINE DIPTEROCARPACEAE.

A translation of Blanco’s original description for Mocanera malaanonan 
is as follows : Leaves ' ovate, lanceolate, broad, abruptly pointed, whitish 
bbneath. Calyx divided almost to the base into five oblong parts, con- 
stricted a little above the fruit; the three exterior more than 7.5 cm 
long. Fruit oval, free at maturity, surrounded by the calyx, outer 
covering fragile, crowned with a long style, which bears three stigmas, 
and with a seed of three or four lobules in a compartment. Trees of 
some diameter, known at Angat by the rather equivocal name of mala- 
anonan g ; the leaves have a length of a span, they are broad and the new 
ones are whitish and soft beneath. This distinguishes it sufficiently from 
other members of the genus. The tree also gives an odorous resin, but 
in small quantity. 
yidal’s description of 8. polita evidently refers to a narrower form and 
is as follows : Leaves lanceolate-elliptic, acute at apex, rounded at base, 
the margin somewhat undulate; leaf blade 6 to 12 cm by 2 to 4 cm, 
petiole 2 to 3 cm; lateral nerves 12 to 15 pairs, slightly ascending (about 
60°) not very distinct, very smooth in the interspaces. Fruiting calyx 
of a brilliant gray, the part which envelops the nut very round, with 
three long, usually unequal (5 to 8 cm) wings and 2 short and narrow 
(3 cm) reddish-yellow which are much reticulated and with about 10 
nerves. 
It seems that a narrow-leaved and a broad-leaved form of malaanonang 
are recognized by the natives, but they seem to be connected by inter- 
mediate forms and it is for that reason that the two are here classed as 
one species. 
Closely resembling 8. coriacea Burck but with larger and more nearly 
glabrous fruit. Perhaps the same species which was described as S. 
hypocra by Hance from Cochinehina, but usually with a smaller number 
of secondary nerves.
