 very dark green, two to three inches long, very coriaceous 

 and fleshy, on short petioles, ovate obovate or nearly orbi- 

 cular, obtuse or shortly acuminate, rounded or rarely almost 

 cordate at the base. Flowers white, tinged with pink in the 

 centre, in simple umbels, peduncles infcerpetiolar, rarely 

 exceeding the petioles ; pedicels pubescent, slender, half to 

 one inch long, or even more. Calyx-segments about one line 

 long. Corolla spreading to half an inch diameter, broadly 

 five-lobed, the upper surface nearly smooth and glabrous, 

 except towards the edges, which are slightly papillose and 

 not reflexed. Corona-segments expanded into concave (at 

 first almost cup-shaped) horizontally spreading laminae, very 

 obtuse on the outer margin, the inner margin acuminate 

 and incurved, the back prominently two-keeled.— G. BentL
