13 cm longis, basi rotundatis, leviter cordatis, apice tenuiter 
caudato-acuminatis, margine irregulariter dentatis; petiolo 15 cm 
longo; inflorescentiis foliis subaequantibus, paucifloris; floribus 
é@ circiter 3 cm diametro. 
An entirely glabrous herb, the rhizomes creeping, simple, 
about 5 mm in diameter, supplied with numerous, lanceolate, 
caudate-acuminate, brown stipules, 1 to 1.5 cmin length. Leaves 
pale-green on both surfaces when fresh, when dry membrana- 
ceous, somewhat shiny, oblong to oblong-lanceolate, nearly equi- 
lateral, 7 to 13 cm long, 2.5 to 4 cm wide, base rounded and very 
slightly cordate, narrowed upward from the lower one-third to 
the slenderly caudate-acuminate apex, the margin irregularly 
toothed, a few of the teeth rather large, most of them small; 
basal nerves about 8 ascending, a few lateral nerves leaving the 
midrib at and above the middle; petioles about 15 cm long. Pe- 
duncles of the staminate inflorescences 19 to 24 cm long, usually 
with 2 short branches at the apex, each bearing about 2 rela- 
tively large white flowers about 3 cm in diameter. Sepals 2, 
oblong-elliptic rounded, about 1.8 mm long, 10 mm wide. Petals 
narrowly oblong, equaling the sepals, 3 to 3.5 mm wide, rounded. 
Stamens about 35, the anthers oblong, about 1.5 mm long; fila- 
ments about 1 to 2 mm long.

This species is not closely allied to any previously described 
Philippine form and is very strongly characterized by being en- 
tirely glabrous; by its nearly equilateral, oblong-lanceolate to lan- 
ceolate, caudate-acuminate leaves which are slightly cordate at 
the base; by its long peduncles; and its few, comparatively large, 
white flowers. 
BEGONIA OBTUSIFOLIA sp. nov. § Diploclinium. 
Herba prostrata, petiolis et subtus foliis ad nervis adpresse 
ferrugineo-pubescentibus; foliis longe petiolatis, oblongis, inae- 
quilateralibus, 7 ad 10 cm longis, apice obtuse rotundatis, basi 
leviter oblique cordatis, margine late lobatis vel undulatis, lobis 
rotundatis; inflorescentiis quam foliis longioribus, paucifloris; 
floribus ¢ circiter 3 cm diametro; capsulis aequaliter 3-alatis, 
junioribus circiter 14 mm latis et 10 mm longis, apice subtrun- 
catis, basi rotundatis. 
Rhizomes slender, creeping, the petioles and nerves on the 
lower surface of the leaves appressed ferruginous-pubescent.
