AGAVES OF THE GROUP APPLANATAE. 95 
em., erect-spreading: spine somewhat flexuous, from garnet becoming 
blackish gray, 3 20mm., openly grooved nearly to the end, rather 
long-decurrent: prickles similarly colored, 15-25 mm. apart, 2-3 mm. 
long, straight or variously and often abruptly curved in either direc- 
tion, narrowly triangular, somewhat lunately widened onto the tops 
of low fleshy prominences between which the margin is rather straight. 
Inflorescence 3 m. or exceptionally 5 high, the upper third oblong- 
paniculate, with nearly horizontal branches: pedicels about 2 < 5-10 
mm. Flowers yellow, fragrant, 25-40 mm. long; ovary about 20 mm. 
long, oblong; tube open and shallow, about 3 mm. deep; segments 
about 3 15 mm., much exceeding the tube but considerably shorter 
than the ovary: filaments inserted in the throat, scarcely 20 mm. long 
or twice as long as the segments. Capsules purplish, small, 15 x 25 
mm., oblong-pyriform, somewhat contracted at base and apex: seeds 
3-4 < 5-6 mm. 
West-central Arizona.—Pl. 94-97. 
Specimens examined :—Arizona. Date Creek, Fort Whip- 
ple (Coues & Palmer, 263, June 5, 1865,—the type). Pres- 
cott (Miss Kate T. Cory, September 1911). 
' An interesting species, long-overlooked, which should 
prove to be one of the hardiest in cultivation, since it with- 
stands a winter temperature often below 0°F. 
For the material on which its general characters are based, 
I am indebted to the interest of Dr. R. E. Kunzé and the 
kindness and energy of Miss Cory, to whom the habit photo- 
graph is also due.
