well as by its very slender, greatly elongated rhizomes; the 
internodes vary from 1 to 3 cm in length. 
BEGONIA PANAYENSIS sp. nov. § Petermannia. 
Herba suffruticosa, erecta, ramosa, glabra, circiter 1.5 m alta; 
foliis in siccitate membranaceis, nitidis, oblongis, usque ad 20 cm 
longis, inaequilateralibus, apice angustatis, tenuiter acuminatis, 
basi rotundatis, baud cordatis, margine distanter et irregulariter 
dentatis; inflorescentiis terminalibus, cymoso-paniculatis, usque 
ad 17 cm longis; floribus S numerosis, circiter 1.5 cm diametro; 
sepalis orbicularis, 7 ad 8 mm diametro; petalis 0; capsulis 
ellipticis vel obovato-ellipticis, circiter 2.5 cm longis et 2 cm 
latis, aequaliter 3-alatis, apice truncato-rotundatis, basi vix an- 
gustatis, rotundatis. 
An erect, branched, glabrous, suffrutescent herb, about 1.5 
m high, the stems and branches stout. Leaves when dry mem- 
branaceous, shining, inequilateral, oblong, 16 to 20 cm long, 
4 to 6 cm wide, narrowed upward to the slenderly acuminate 
apex and somewhat narrowed below to the rounded base, or the 
narrower side of the lamina acute and the broader side rounded, 
not at all cordate, margins distantly and irregularly dentate, 
or that of the narrower side often nearly entire except near 
the apex; nerves prominent, ascending; petioles stout, 1 to 1.5 
cm long; stipules membranaceous, oblong to oblong-lanceolate, 
acuminate, 1.5 to 2 cm long. Inflorescences terminal, cymose- 
paniculate, up to 17 cm in length, the staminate flowers numer- 
ous, the pistillate flowers apparently few and only at the base 
of the inflorescence, none present on the type, but represented 
by mature capsules. Staminate flowers pink, about 1.5 cm in 
diameter. Sepals orbicular, 7 to 8 mm in diameter. Petals 
none. Stamens about 35, the anthers narrowly oblong to oblong- 
obovoid, 1.2 to 1.5 mm long, longer than the filaments. Cap- 
sules one or two at the base of the inflorescence, including the 
three equal wings about 2.5 cm long, 2 cm wide, elliptic to 
obovate-elliptic, apex rounded-truncate, base scarcely narrowed, 
usually rounded; pedicels 1,5 to 2 cm long.

This unusually robust species is manifestly allied to Begonia 
longistipula Merr., from which it is distinguished by its larger 
leaves and flowers and by its much larger, differently shaped 
capsules.
