PHILIPPINE SPECIES OF BEGONIA. 
399 
ad 15 cm diametro, integris, plus minus obliquis, basi cordatis, apice 
brevissime acuminatis ; floribus masculinus sepalis 6 ad 7 mm diametro, 
extus parce ciliato-setosis ; petalis 2, obovatis ; staminibus cireiter 40 ; 
capsulis obliquis, cireiter 1.5 cm longis, 5-alatis, alis inaequalibus, una 
lata, concava, aliis multo angustioribus, planis. 
Stems prostrate, creeping and rooting, red when fresh, setose-ciliate 
with brown hairs. Leaves suborbicular to subreniform, somewhat obli- 
que, 5 to 15 cm long, often a little wider, entire, when fresh very thick 
and fleshy, firmly chartaceous when dry, base deeply cordate, apex with 
a short, stout, lateral acumen, the upper surface glabrous except for few 
long brown hairs on the nerves, the lower surface brown when dry, the 
nerves densely brown-setose-ciliate ; nerves about 9, radiate, often forked ; 
petioles red when fresh, stout, 8 to 15 cm long, densely brown-setose- 
ciliate; stipules ovate, acuminate, brown-setose, about 1 cm long. In- 
florescence as long as the leaves and petioles, erect, glabrous or nearly 
so, branched at the top, the branches divaricate or spreading, few-flowered, 
the bracteoles small, deciduous. Male flowers pink. Sepals 2, subor- 
bicular, rounded, 6 to 7 mm in diameter, slightly brown-setose on the 
nerves outside. Petals 2, oblong-obovate. Stamens about 40; filaments 
free or nearly so, nearly as long as the anthers, which are oblongs about 
1.5 mm long, the connective slightly produced. Female flowers not seen. 
Capsules oblique, about 1.5 cm long and 2 cm wide with one large concave, 
oblique wing, and 5 subequal much narrower ones. 
Palawan, Malampaya Bay, Merrill 7229, September 18, 1910, on ledges in 
forests near the seashore. 
A very characteristic species on account of its 5-winged capsules, one wing being 
concave and very much larger than the other four which are flat. Perhaps not 
truly referable to the section Diploclinium.

This species was based on Lobb 465, but on account of the different localities 
given on the labels, A. DeCandolle considered the original home of the plant to 
be uncertain; on the four specimens of this number examined by him, one label 
(Kew) gave the locality as Luzon, one (St. Petersburg), gave the locality as Java, 
and two gave no locality. As the species is not uncommon in central Luzon, 
and as it has not as yet been found outside of the Philippines, it is safe to 
assume that in this case the locality given on the Kew label is correct. It has 
been assumed by some botanists that the localities given on Lobb’s plants in the 
Kew set are the correct ones, but this is certainly not always the case. About 
seven species so far credited to the Philippines solely on the authority of Lobb’s 
specimens, so labelled, almost certainly did not come from the Archipelago, but
