Bur. Sci. 23490 Ramos, August 3, 1915, with staminate flowers 

 and the local Bikol name buyong halas: Laguna Province, Mount 

 Maquiling, For. Bur. 26751 Mabesa, March, 1917, Elmer 18059, 

 June, 1917. In damp forests at low and medium altitudes, as- 

 cending to 450 meters on Mount Maquiling. 



A remarkable species not at all resembling any previously 

 described form, easily recognizable by its broadly ovate, deeply 

 cordate, equilateral leaves which are softly pubescent beneath; 

 by its rather stout, cylindric, elongated spikes and their pubes- 

 cent bracts ; and by its large, long-pedicelled fruits.

Arbor magna, plus minusve pubescens; foliis tenuiter char-

A tree, about 25 m high, more or less pubescent. Leaves 

 thinly chartaceous, rather scabrous, both surfaces with scat- 

 tered, very short hairs, ovate, entire, 5 to 8 cm long, 3 to 5 cm 

 wide, the base inequilateral, 3-nerved, somewhat oblique-truncate 

 to rounded or even shallowly cordate, the younger leaves some- 

 times acute, apex acuminate; nerves slender, including the basal 

 pair usually 3 on each side of the midrib; petioles pubescent, 

 about 5 mm long. Inflorescences axillary and from the axils of 

 fallen leaves, the latter usually wholly staminate, the former with 

 both male and perfect flowers, cinereous-pubescent, up to 5 cm 

 long. Male flowers sessile, somewhat glomerate on the branch- 

 lets, 5-merous, about 4 mm in diameter, the sepals distinctly 

 pubescent, oblong-obovate, 2 mm long. Stamens equaling the 

 sepals. Perfect flowers fewer than the male, sessile or short- 

 pedicelled, the sepals 5, elliptic to oblong-elliptic, 2 to 2.5 mm 

 long. Ovary oblong-ovoid, pubescent, the style arms forked. 

 Stamens 5, filaments 2 mm long.

 the local Tagakaolo name sikim. 



This species does not appear to be very closely allied to any 

 previously described form. It is easily distinguished among 

 the Oriental species with entire leaves by its indumentum and
