surface with much more numerous setae ; lateral nerves 10 to 12 
on each side of the midrib, prominent, curved, anastomosing, 
the reticulations prominent; petioles densely setose, 1.5 to 2.5 
cm long. Flowers axillary, solitary, the pedicels and the sepals 
externally very densely setose, the pedicels, in fruit, 2 to 4 cm 
long, often with one or two scars at about the middle. Sepals 
subcoriaceous, elliptic-ovate to broadly ovate, or the inner ones 
obovate, 12 to 14 mm long, very densely setose, glabrous inside, 
the marginal parts of the inner ones thinner, mostly acute. 
Fruit capsular, about 12 mm long, subellipsoid, 4-celled, ex- 
ternally puberulent, dehiscing in the upper part only.

rez, March 21, 1916, in dipterocarp forests, altitude about 1,000 meters, 
locally known as carimog. 
A very characteristic species, distinguishable by its long-pedicelled, 
rather large flowers; its dense indumentum which consists of pale-brownish, 
spreading, acuminate, rather soft setae, the setae themselves puberulent; 
and its capsular fruits.

Frutex circiter 2 m altus vix setosus, subtus foliis et inflor-

A shrub about 2 m high, the younger branchlets, petioles, in- 
florescences, and lower surface of the leaves very densely cinna- 
momeous-pubescent, the indumentum felted. Branches terete, 
dark reddish-brown, glabrous, the branchlets and petioles with 
few, widely scattered, appressed, oblong-ovate scales 2 mm long 
or less. Leaves chartaceous, oblong to oblanceolate, 11 to 20 
cm long, 4 to 8 cm wide, narrowed below to the cuneate base, 
the apex shortly and sharply acuminate, the margins, except at 
the base, conspicuously denticulate with somewhat spreading, 
oblong-obtuse, gland-like teeth about 1 mm in length, the upper 
surface smooth, glabrous, or when young sparingly puberulent, 
dark-brown or dark-olivaceous, in striking contrast to the densely 
cinnamomeous-pubescent lower surface where the indumentum 
is closely felted; lateral nerves 13 to 15 on each side of the
