310 MERRILL. 



differs especially in its smaller size, and in its smaller entire leaves which 

 are nearly glabrous on the upper surface, not prominently ciliate with 

 long hairs. In habit and general appearance it approximates some species 

 of Elatostevia, from which the specific name. 



BEGONIA OBLONGATA sp. nov. § Petermannia. 



Species B. contractae Warb. affinis, differt foliis angustioribus, 

 valde oblique cordatis, capsulis majoribus, circiter 15 mm longis. 



An erect, glabrous, sparingly branched, succulent herb up to 

 60 cm in height, the stems often somewhat prostrate below, the 

 nodes sometimes emitting rootlets. Leaves membranaceous, 

 green, oblong to oblong-lanceolate, 8 to 12 cm long, 1.2 to 3 cm 

 wide, often somewhat falcate, gradually narrowed above and 

 slenderly acuminate, the base very strongly inequilateral, cordate, 

 the sinus lateral, the lower lobe very much larger than the upper 

 one, usually about 2 cm wide, rounded-angular, the upper lobe 

 acute or slightly rounded, about 5 mm wide, the sinus narrow, 

 acute, the lobes not overlapping ; basal nerves 1 or 2 in the narrow 

 lobe, 4 or 5 in the broader one, radiate, the lateral ones above 

 the base 2 to 4, ascending, anastomosing, the margins rather 

 prominently but irregularly toothed; petioles 1.5 to 3 cm long; 

 stipules membranaceous, oblong-lanceolate, acuminate, about 1 

 cm long. Inflorescence terminal, slender, 6 cm long or less, 

 divaricately branched, few-flowered, the basal flower female, 

 the upper ones male. Male flowers : Sepals 2, suborbicular, pink, 

 rounded, about 4 mm in diameter, slenderly 7-nerved. Petals 

 none. Stamens 30 to 35 ; anthers obovoid, slightly refuse, 0.8 to 

 1 mm long, the filaments less than 1 mm in length. Female 

 flowers not seen. Capsules ovoid, truncate, about 15 mm long, 

 15 to 17 mm wide, equally 3-winged, the outer angles of the wings 

 subacute, the base broadly rounded.

 rill 8166 (type) 8175, December 6, 1911, in damp shaded ravines, altitude 

 100 m and above. 



A species manifestly allied to Begonia contracta Warb., but differing in 

 a number of characters, especially in its relatively narrow leaves and its 

 much larger capsules. 



BEGONIA MACGREGORII sp. nov. § Petermannia. 



Species ut videtur B. cumingii A. Gray affinis, differt floribus 

 masculinis multo minoribus, partibus junioribus ramisque longe 

 ciliato-setosis. 



An erect or ascending sparingly branched plant 20 to 100 cm 

 high, the stems with numerous, long, slender, brownish, ciliate-
