what ciliate, about 1 cm long, and with a few fimbriate-ciliate 

 paleae. Inf ructescences long-peduncled, 20 to 30 cm 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.

 June 7, 1918, altitude about 1,000 meters. 



This species is allied to Begonia, copelandii Merr. and B. alva- 

 rezii 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. § Diploclinium. 



Herba prostrata, repens, leviter ciliatis, internodiis 1 ad 3 

 cm 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 3 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 cm. Leaves irregularly rhomboid, inequilateral, 

 base more or less cordate, apex shortly acuminate, 1.5 to 2.5 

 cm 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. 



Panay, Antique Province, Culasi, Bur. Sci. 32588 (type), 

 S25U McGregor, May and June, 1918, on damp forested slopes, 

 altitude 500 to 900 meters. 



This species is as closely allied to, Begonia nigritarum Steud. 

 as to any other but is readily distinguished by its smaller leaves, 

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