PHILIPPINE PLANTS, IX. 309 



the inner three as long as the outer ones, about 4 mm wide, 

 slenderly 5-nerved. Styles 3, forked, 4 mm long ; stigmas spirally 

 arranged. Capsules about 1.5 cm long, 1.5 to 2 cm wide, equally 

 3-winged, somewhat depressed-rhomboid in outline, the wings 

 subequally rounded at their tips. 



Mindanao, District of Zamboanga, Sax River Mountains back of San 

 Ramon, Merrill 8251 (type), 82^8, November 27, 1911, in damp ravines, 

 altitude about 900 m. 



A species manifestly closely allied to Begonia agusanensis Merr., dis- 

 tinguished chiefly by its larger capsules and its densely ciliate branchlets. 



BEGONIA ELATOSTEMATOIDES sp. nov. § Petermannia. 



Species B. ciliiferae affinis, differt foliis minoribus, integris vel 

 subintegris. 



An erect or ascending, simple or slightly branched suffrutes- 

 cent herb, the stems often prostrate below, 20 to 40 cm high, 

 the stems, petioles, and lower surfaces of the leaves, at least on 

 the veins, prominently ciliate with brown hairs. Leaves green 

 above, red beneath when fresh, membranaceous, oblong to nar- 

 rowly oblong-obovate, often subequally narrowed at both ends, 

 3.5 to 7 cm long, 1 to 2.5 cm wide, slightly acuminate, entire, 

 base slightly inequilateral and slightly cordate, the upper surface 

 with very few, short, scattered, brown hairs or nearly glabrous, 

 the lower surface prominently ciliate with brown hairs on the 

 nerves, and with scattered shorter hairs on the surface; nerves 

 pinnately arranged, 3 or 4 on each side of the midrib, ascending ; 

 stipules lanceolate, acuminate, brown-ciliate, about 1 mm long; 

 petioles 1 to 3 mm long. Flowers pink and white, in axillary 

 fascicles, but one or two opening at a time. Male flowers : Ped- 

 icels slender, 4 to 5 mm long, subtended by several, lanceolate, 

 long-acuminate, brown-ciliate bracts about 2 mm wide, 5 to 7 

 mm long, their margins prominently fimbriate-ciliate. Sepals 2, 

 broadly ovate, acute, 8 to 9 mm long, 5 to 6 mm wide, slenderly 

 7-nerved, outside with few, scattered, short hairs. Petals 2, 

 oblong, obtuse, about 6 mm long, 2 mm wide. Stamens about 

 30, the torus somewhat elongated; filaments about 0.5 mm long; 

 anthers oblong-obovate, retuse, about 1 mm long. Capsules 

 broadly subrhomboid-obovate, truncate, about 8 mm long, 1 cm 

 wide, equally 3-winged, the outer upper angles of the wings 

 subacute, base narrowed and acute. 



Mindanao, District of Zamboanga, Sax River Mountains back of San 

 Ramon, Merrill 8232, November 27, 1911, in damp shaded ravines, and on 

 forested slopes, altitude 800 to 1000 m. 



A species manifestly closely allied to Begonia ciliifera Merr., a species 

 also known only from the Zamboanga Peninsula. The present species
