vailingly down-curved below and upcurved above, little widened onto 
the tops of low fleshy prominences between which the margin is some- 
what concave. Inflorescence 3-4 m. high, the upper third or less pan- 
iculate with short outcurved-ascending little-divided branches: pedi- ~ 
cels 2-8 mm. long. Flowers light yellow,45-50 mm. long: ovary 25-30 
mm. long, fusiform: tube deep for the group, about 10mm. : segments 
attenuate, short, 5X 15 mm., one-half longer than the tube and about 
half as long as the ovary: filaments inserted nearly in the throat of 
the tube, scarcely 25 mm. long and less than twice as long as the seg- 
ments. Capsules brown, oblong or pyriform, 15-20 30-50 mm., not 
stipitate but somewhat beaked: ‘‘seeds 3-4 mm. in diameter, smooth.’’
