and 7 mm. in length. The flowers are yellowish, 14 mm. 
long, average diameter in bnd 3 mm., diameter of open 
flower 10 mm. (See pi. VII., figs. 8 and 9.) 
Calyx brown, densely pnbescent, 7 mm. long ; segments 
4-5, accrescent, acute apex, 4 mm. long. 
Corolla yellow, segments and throat covered with 
yellowish-brown hairs, 16 mm. long when open; segments 
4-5, rotate, very hairy on half of under surface, tapering 
acuminate apex, 4 mm. long. 
Stamens 5-7-9,epipetalous,glabrous, separate or united in 
pairs, unequal in length ; often the inner stamen of a pair 
is very small and contains very little pollen; anthers 
yellowish-brown, apieulate, 3 mm. long; filaments white, 
2 mm. long; pollen circular, yellowish-green, thick-walled, 
granular contents. 
Pistil absent or rudiment of unicellular hairs terminating 
receptacle. 
The female inflorescence is sessile and usually consists of

Calyx large, 12 mm. long, brown, both surfaces densely 
pubescent; segments 5-6, lanceolate, tapering acute apex, 
accrescent, small intersegmental groove, margins straight, 
Corolla yellow, large, 18 mm. long, diameter at base 6 mm., 
diameter of open flower 14 mm., outer surface pubescent; 
segments 5-6, rotate, reflexed, hairy beneath, subglabrous 
above, tapering apex, base 5*5 mm. wide, length 5*5 mm.
