Mexico. 
Stems attaining a height of twelve to eighteen inches, three- 
fourths to one inch thick, light green, the scars roundish-oblong. 
Leaves laxly aggregated towards the summit of the stem, obovate- 
spathulate, when fully developed two to two and a half inches 
long by one to one and a quarter inch broad three-quarters of the 
way up, the apex rounded to a blunt point, the lower two-thirds 
spathulately narrowed, the centre of the lamina half an inch 
thick, the face decidedly flattened, the back rounded, both sides a 
bright ight apple-green, not glaucous. lowering branch more 
than a foot long, its leaves few and scattered, oblong, an inch or 
less long. Flowers twenty to thirty in a moderately close 
drooping equilateral raceme, which is sometimes a little com- 
pound towards the base. Bracts narrow-oblong, very thick, 
three-eighths to half an inch long, exceeding the simple pedicels, 
which are spreading or the lower ones deflexed. Sepals linear- 
lanceolate, equal, very thick, appressed to the corolla, which is 
dull straw-coloured, three-eighths of an inch long and hardly at 
all pentagonal.—J. G. B. 
This robust and remarkable species will grow freely in any 
ordinary greenhouse, if kept moderately dry at the roots during 
the winter months. It should be potted in a mixture of turfy 
loam and sand, and is easily increased by cuttings or by the 
leaves, which will root readily if placed in light sandy soil, the 
larger portion of the leaf being above the ground. My plants 
were obtained from one of the Belgium nurseries.—W. W. S.
