from North Mexico, through Texas, to Arizona. It has been said that its 
flowers, contrary to the habit of the genus (which has diurnal flowers—i. é, 
open in sunlight), are nocturnal, which, however, is now positively denied.

* FicoipbE£.— “A miscellaneous group, chiefly of fleshy or succulent plants, with mostly opposite 
leaves and no stipules; differing from Caryophyllacee and Portulacacew by havin g distinct partitions to 
the ovary and capsule (which are therefore 2-many-celled) ; the petals and stamens sometimes numerous 
in the manner of Cactacew (but the former wanting in most of the genera) ; agreeing with all these 
orders in the campylotropous or amphitropous seeds; the slender embryo curved partly or completely 
round a mealy albumen.”—FI. Cal. p. 250.

small, depressed, styles rather short. Fruit ovate, slightly compressed on the side, commissure rather 
broad ; carpels 5-angled, a little compressed on the back, with the primary ribs filiform, rather promi- 
nent, lateral ones contiguous. Vitts many. Carpophore bifid. Seed compressed a little on the back, 
with the sides a little incurved.—Perennial, cxspitose herbs, branching from the base, smooth. Leaves
