long, 0.5 to 1 cm. broad, very oblique, glaucous beneath, blunt, crenate- 



serrate, sparingly pilose; stipules setaceous: cymes dense, 1 or 2 cm.

1 In tlie preparation of the descriptions of these Euphorbias the writer lias 

 been greatly assisted by Professor C. I'. Millspaugh, who lias generously examined 

 mens, and who baa already pointed out (Bot. (Jaz. xxr. 13) the impor-
