axillary in few-flowered racemose panicles. Occasionally two inflores- 
cences from one axil. Eachis of inflorescence brownish pubescent. Fruit 
3 to 4 mm in diameter, 4 to 5 mm long; resin-cavities in lower part of 
fruit. Fruiting calyx with 2 long wings 3.5 to 4.3 cm long and 10 to 15 
mm wide, with about 9 principal veins. Wings yellow when dry, the veins, 
being of darker color and the fruit and base of wings very dark-brown. 
The bases of these two larger wings are expanded so as practically to 
conceal the small wings. 
Differs from H. odorata in shape of leaves and in its thick short petioles, 
in size of fruit and in expanded bases of the two enlarged calyx wings; 
from II. plagata in its narrower leaves, shorter petioles, smaller fruit, with 
expanded bases to calyx wings ; from H. philippinensis in fruit and the 
absence of the long stipules.
