description. I have examined the specimen collected by Lobb (herb. Kew. ), cited 
by A. DeCandolle as doubtfully referable to B. manillensis, but consider Lobb’s 
specimen rather referable to Begonia, luzonensis Warb. 
Endemic. 
56. Begonia alvarezii sp. nov. 
Herba succulenta partibus basilaribus brunneo-ciliatis exceptis glabra; 
foliis 11 ad 18 cm longis, in siccitate membranaceis, oblique oblongo- 
ovatis, integris, basi lateraliter valde cordatis, apice rotundatis; pedun- 
culis elongatis, quam folia longioribns ; floribus ignotis ; capsulis 
obovatis, circiter 15 mm longis, 15 ad 18 mm latis, basi acutis, apice late 
rotundatis vel truneatis, inaequaliter 3-alatis. 
A succulent herb the rootstocks and bases of the petioles and peduncles

glabrous or nearly so. Leaves oblong-ovate, membranaceous when dry, 
entire, 11 to 18 cm long, 6 to 11 cm wide, the apex rounded, the base 
laterally deeply cordate, the sinus narrow, both lobes broadly rounded; 
nerves about 10, radiate; petioles 11 to 20 cm long. Peduncles up to 
40 cm in length, dichotomously branched above, the capsule bearing parts 
10 to 12 cm long. Flowers unknown. Capsules broadly obovate, about 
15 mm long, 15 to 18 mm wide, unequally 3-winged, the base subacute,

Well characterized by its entire leaves, the whole plant being glabrous except 
for the long brown ciliate hairs at the base. 
57. Begonia gracilipes sp. nov. 
Suffruticosa, scandens, ramulis petiolisque parcissime setosis exceptis 
glabra; caulibus radicantibus, brunneis; foliis leviter oblique ovatis,

gulariter dentatis denticulatisque, vix lobatis, membranaceis, usque ad 8 
cm longis, petiolo 5 ad 7 cm longo; inflorescentiis axillaribus, brevibus, 
paucifloris ; floribus masculinis longe pedicellatis, circiter 2 cm diametro ; 
capsulis turbinatis, circiter 1.8 cm diametro, aequaliter 3-alatis.
