what ciliate, about 1 cm long, and with a few fimbriate-ciliate 
paleae. Infructescences long-peduncled, 20 to 30 em long, nearly 
glabrous, dichotomously branched at the apex of the peduncle, 
the primary branches about 5 cm long. Capsules few, including 
the wings about 12 mm long and 23 mm wide, inequally 3- 
winged, one wing about twice as large as the other two, the 
apex subtruncate, base broadly rounded, the outer upper angles 
of the wings rounded or obtuse.

_ This species is allied to Begonia copelandii Merr. and B. alva- 
rezti Merr., but its indumentum is very different from both. 
The leaves are characteristically reddish-purple on both sur- 
faces when dry. 
BEGONIA SERPENS sp. nov. § Diplocliniwm. 
Herba prostrata, repens, leviter ciliatis, internodiis 1 ad 3 
em longis; foliis breviter petiolatis, irregulariter rhomboideis, 
inaequilateralibus, 1.5 cm diametro, basi leviter cordatis, apice 
acutis vel acuminatis, margine irregulariter lobatis; inflorescen- 
tiis paucifloris, circiter 8 cm longis; floribus ¢ circiter 1.5 cm 
diametro. 
A very small, slender, prostrate, sparingly appressed-ciliate 
herb, the rhizomes 2 mm or less in diameter, attaining a length 
of at least 25 em. Leaves irregularly rhomboid, inequilateral, 
base more or less cordate, apex shortly acuminate, 1.5 to 2.5 
em in diameter, margins shallowly and irregularly lobed, the 
upper surface usually mottled with gray, glabrous, the lower 
surface sparingly ciliate on the nerves with appressed brown 
hairs, the margins more or less ciliate with short spreading 
hairs; petioles 1 to 1.5 cm long, sparingly ciliate; stipules brown, 
5 to 6 mm long, oblong-ovate, with a long slender tip. Peduncles 
slender, about 3 cm long, usually 2-flowered. Staminate flowers 
usually pink, about 1.5 cm in diameter. Sepals broadly obovate, 
rounded, 7 to 8 mm long, 6 to 7 mm wide. Petals equaling the 
sepals, oblong-obovate, rounded, 4 mm wide. Stamens about 35; 
anthers oblong-obovoid, 0.8 mm long; filaments 1 mm long or less.

This species is as closely allied to Begonia nigritarum Steud.

short petioles, and short, very few-flowered inflorescences as
