Sandy bottoms of the Rio Grande at El Paso: flowers May and June. Stems 5-8 inches high, somewhat cespi- 
tose, of a pale green color, and a soft spied texture : ribs broad, fewer ; radial spines 6-12 or 15 ae ~_ central 
spines 14-3 inches long, flowers 2$ inches long, with fewer and narrower petals. Fruit 1-1} in ng, 
covered with bunches of spines which, as in the last species, on the flower are indicated only by few a Nis [283] 
bristles, Seed with tubercles confluent, and leaving pits between them. Nearly allied to the two last, but 
sufficiently well distinguished by the characters given.

Var. y. VARIEGATUS, E. & B. 1. c. : aculeis radialibus sub-13 albidis, centralibus 3 superioribus recurvatis divari- 
catis nigris corneo-variegatis, inferiore longiore albo decurvo, 
Lower Gila, Colorado, and westward to the California mountains: flowers June and July. — Stems 5-10 inches 
al spines slender, 3-6 lines, central ones 1-2 inches long. Fruit near the top of the plant. — Dr. Bigelow 
they differ from the species by having the fruit lower down on the plant; the arrangement of the spines, however, 
is entirely identical. Var. 8. has very stout central spines, 2-3 inches long, of a deep golden-yellow color, and the 
lower one shorter. In var. y. the central spines are only 1-2 inches long, much curved, and the upper ones white 
and black mottled. 
* * Coccinei; floribus diu noctuque apertis.

N in western New Mexieo co, under cedars. — Radial spines 8-15 lines long, upper one and central spine 
lg AO long, remarkably stout, angular and channelled. —I have not seen the flower of this — but place it 
ts resemblance to the next species ; on the other hand, it seems to be allied to C. Mojavensis
