Luzon, Province of Cagayan, Claveria, Bur. Sei. 1393 (type), 7881 Ramos, 
March, 1909, on rocks along streams.

suhorbicular-ovate, entire leaves. 
35. Begonia rufipila sp. nov. 
Species B. hernandioidei valde affinis, differt omnibus partibus, prac- 
sertim junioribus, plus minus dense molliter rufo-villosis. 
An herbaceous plant, the rootstock creeping. Stipules linear or linear- 
lanceolate, about 1 cm long, acuminate, densely brown-viilous. Leaves 
ovate or suborbicular-ovate, peltate, entire, base broad, apex somewhat 
lateral, acuminate, membranaceous, 6 to 9 cm long, 4 to 6 cm wide, the 
lower surface with numerous, long, soft, brown hairs, the upper surface 
ultimately nearly glabrous, radiately about 9-nerved ; petioles 5 to 8 cm 
long, densely villous with long, soft, brown hairs, inserted at about 1.5 
em from the basal margin of the leaf-blade. Inflorescence about as long 
as the leaves, dichotomously branched above, ultimately nearly glabrous. 
Flowers unknown. Capsules about 12 mm long, 15 mm wide, the ba?e 
acute, the apex truncate, unequally 3-winged, the wings reticulate, one 
about 6 mm wide, the other two about one-half as wide. 
Luzon, Province of Ilocos Sur, Dolores, For. Bur. 566o Klcmmc, October 31, 
1906, on moist boulders in shaded places. 
A species similar to and manifestly very cicely allied to Begonia he^ti^n- 
noides Merr., differing manifestly in its rather dense, brown indumentTim which is 
composed of long, soft, hairs.

^' 'Amon>r the numerous specimens of this genus in our herbarium I have found 
none tliat agree at all well with the description of the above species. It seems 
to be well characterized by its capsules which are described as 6 lines long, 4 
lines wide, with equal wings a line in width.
