1839, bearing both flowers and young fruit. In Prerrrer’s 
** Enumeratio Cactearum,” it is placed next to the well- 
known Cereus flagelliformis (that frequent ornament of 
cottage windows), but may readily be known by its differ- 
ent mode of growth, its deeply furrowed stem, and much 
slenderer hair-like aculei. It is a native of Mexico, and 
flowers readily and copiously in the spring months. 
Descr. Stem nearly erect, but weak, branched, terete, 
obtuse, about three-fourths of an inch in diameter, about 
eight-angled, the angles obtuse : studded with areola about 
half an inch asunder, each containing a small white tuft, 
whence arise six to eight hair-like aculei. Flowers large, 
handsome, of a deep-red rose-colour. Calyx of several 
narrow-lanceolate, acuminated scales, gradually enlarging, 
and passing into numerous spreading petals. Germen sub- 
globose, and, as well as the elongated tube of the flower, 
beset with tufts of hair-like aculei. Young fruit globose, 
green, larger than a hasel-nut, and partially clothed with 
the persistent tufts of hairs.
