PHILIPPINE SPECIES OF BEGONIA. 
393 
cm long, 1.5 cm wide, the apex truncate, the base subtruncate or broadly- 
rounded, unequally 3 -winged, one wing nearly 1 cm wide, obtuse or 
subacute, the other two wings rounded, less than 5 mm wide, all reticulate. 
Placentae 2-partite. Pedicels in fruit about 1.5 cm long. 
Luzon, Province of Cagayan, Claveria, Bur. Sci. 7393 (type), 7387 Ramos, 
March, 1909, on rocks along streams. 
A strongly marked species, well characterized by its broadly peltate, glabrous, 
suborbicular-ovate, entire leaves. 
35. Begonia rufipila sp. nov. 
Species B. hernandioidei valde affinis, dilfert omnibus partibus, prae- 
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-villous. 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 
cm 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 base 
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. 5665 Klemme, October 31, 
1906, on moist boulders in shaded places. 
A species similar to and manifestly very closely allied to Begonia hernan- 
dioides Merr., differing manifestly in its rather dense, brown indumentum which is 
composed of long, soft, hairs. 
36. Begonia longovillosa A. DC. in Ann. Sci. Nat. IV 1 1 (1859) 130, Prodr.

Among the numerous specimens of this genus in our herbarium I have found 
none that 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. 
37. Begonia longiscapa Warb. in Perk. Frag. FI. Philip. (1904) 52. 
Leyte, Jagor s. n., 1861, type in herb. Berol. ! 
This species does not appear to be matched in any of the recent collections.
