Opuntia hybrids and selected types. Hybrids 
are frequent among the Opuntias, and I 
have selected and propagated several of 
the finest small-growing types; nursery - 
grown plants. 
Juniperus scopulorum 
Opuntia, Apache. (Rutila x polyacantha.) 
Thick, oblong joints, connected in an 
erect clump formation to 10 or 12 inches

numerous and ferocious brown-red spines. 
Outstanding, and attracts much atten¬ 
tion. 50c. 
Opuntia, Cimarron (fragilis x rutila). A 
high-altitude form of extra hardiness; 
small semi-cylindrical joints, strongly 
tinged red or purple, flowers apricot- 
yellow. A gem for the small garden. 50c.

flowering profusely. Flowers yellow, 
with red center, and a crown (corona) 
of red filaments. 50c.

large-growing variety with few spines. 
Flowers very showy, yellow, with a red 
center and deep red filaments. 50c.
