10. C. Fendleri, E. in PI. Fendl. : ovato-cylindricus; costis 9 - 
12 ; areolis subconfertis ; aculeis basi bulbosis, radialibus 7- 10 rectis 
seu curvatis albidis et fuscis, inferioribus robustioribus, centrali va-

New Mexico, from Santa Fe to below El Paso, and from east of 
the Pecos to Zuni: fl. in May and June. — Stems 3-8 inches high, 
not many from the same base ; spines very variable, but always very 
bulbous at the base, and some of them white, some deep brown or 
black, and others party-colored ; radial ones £ - 1 inch, and the cen¬ 
tral one 1-2 inches long. Flower 2\ - 3| inches in diameter, of a 
deep purple color. Berry 1 - 1J inch long, edible. Seed deeply and 
irregularly pitted by the confluence of many of the tubercles, un¬ 
usually oblique.

pitosus, glaucescens, 10 - 12 costatus; areolis remotis ; aculeis va- 
lidis curvatis, radialibus 7 — 8, lateralibus robustioribus longioribus, 
centrali singulo sursum curvato elongato. 
Var. /3. ? Zuniensis : 10-costatus ; aculeis debilioribus 4-angulatis 
bulbosis rectis vel flexuosis, radialibus 8, summo longiore robustiore; 
centrali recto seu sursum curvato longiore, omnibus bulbosis. 
On the Mojave River in California, and /3. farther east, on the Col¬ 
orado Chiquito. Ovate heads 2-3 inches high, forming dense CEespi- 
tose masses ; ^upper and lower spines 9-15 lines, lateral ones 15 - 
25 lines long, central spine 1$ - 2| inches long, dusky. Var. /3. is 
distinguished by having the upper radial spine almost as stout and 
long as the central spine, the former being 12 - 18, the latter 18-24 
lines long. Both seem to be distinguished from the nearly allied C. 
Fendleri by having the lowest spfties weakest, while in that species 
they are the stoutest of the exterior ones. The resemblance to C.
