An old inhabitant of the Cactus house of the Royal Gardens, 
originally received from Mexico. A very dingy looking species 
except when in flower, when the pure white corollas, with a 
slightly pink tinge, have a very pretty effect. 
Desor. Stem sometimes attaining a height of three feet, 
erect, terete or cylindrical, four to five inches broad, dingy glau- 
cous-green, deeply furrowed longitudinally with about fourteen 
or fifteen furrows, the ridges tuberculate or mamillate ; ma- 
mille large, in a regular series, very convex, oval or obscurely 
six-sided, compressed, the centre having a conspicuous woolly 
areola from whence diverge about eleven sharp aciculated spines, 
of which the greater number are large, tawny in the young state, 
brown when old, always deeper at the base, three or four are 
much the smaller of the cluster. Flowers two or three or more 
together, from the summit of the plant. Calyx-tube dark green, 
glabrous, scaly with remote scales, which upwards gradually 
pass into oblong sepals with white margins, and those again 
into the spreading petals, white, partially tinged with rose, 
the apex slightly serrated and mucronate. Stamens numerous,
