Aspect of A. deserti. Leaves triangular-oblong, essentially smooth, 
about 5 X 15-40 em.: spine drab with glossy brown apex, acicular, 
nearly straight, 3-5 X 25-85 mm., openly grooved below the middle or 
involute: prickles similarly colored, more or less firm, 15-25 mm. 
apart, 3-5 mm. long, triangular, rather straight or upcurved, some- 
what lenticularly hardened into the nearly straight margin. Inflor- 
escence as in A. deserti, with rather more divided branches, about 
2m. high. Flowers 40-50 mm. long: ovary fusiform, in age develop- 
ing a rather long neck, 25-30 mm. long, considerably exceeding the 
perianth; tube 4-6 mm. deep: segments about 4 x 15 mm., much longer 
than the tube and fully half as long as the ovary: filaments inserted 
nearly in the throat, 30-35 mm. long, rather more than twice as long 
as the segments. Capsules beaked, becoming grayish straw-color, 
otherwise strikingly diverse: narrow (12 45 mm.), evidently stipi- 
tate and slender-pediceled; or short (15 < 30-35 mm.), little stipitate 
and stouter-pediceled; seeds 3-4 X 5-7 mm.
