I have not seen this species. If a constant character, the triangular stems 
readily distinguish it from all other species hitherto known.

Stems erect, branching, glabrous ; branches erect, 5-8 in. long, attenuated 
upwards, 4-angled ; angles slightly toothed ; teeth furnished with fleshy 
terete acuminate deciduous leaves 1-3 lin. long. Flowers solitary or 
occasionally two together, subaxillary along the upper part of the stem ; 
pedicels jin. long, elongating to 4-4 in. long when in fruit, glabrous,
