THE AGAVES OF LOWER CALIFORNIA. 53 
branched; pedicels slender, about 5 mm. long, irregularly fasciately 
coherent. Flowers chrome-yellow, rather fetid, about 35 mm. long: 
ovary flask-shaped with a distinct neck, 15-20 mm. long, about equaling 
the perianth; tube 3-4 mm. deep: segments about 4% 15 mm., much 
ionger than the tube but shorter than the ovary: filaments inserted 
nearly in the throat, 25-30 mm. long and nearly twice as long as the 
segments. Capsules about 15 < 45 mm., scarcely stipitate but beaked: 
seeds about 4 5 mm. 
Western border of the Colorado Desert in California at an 
altitude of about 3,000 feet.—Deserti,—of the desert, from 
its habitat. Pl. 41, 42. 
Specimens examined:—Cauirornia. East of San Felipe 
(Emory, 1846; Hitchcock, 1875; Palmer, 1875,—the types). 
Not known to extend into Lower California, but introduced 
here because of the close relationship borne it by the next 
two species.

Aspect of A. deserti, Leaves more oblong, nearly smooth, about 
6 X 20-80 cm.: spine brown, becoming drab toward the base, variously 
acicular-conical or compressed, straight, 3-4>< 25-30 mm., openly 
grooved below the middle or involutely closed: prickles similarly col- 
ored, rather firm, 10-25 or 30 mm. apart, 4-8 mm. long, triangular, 
nearly straight or variously curved, the intervening margin at most 
gently undulated. Inflorescence 5-7 m. high: pedicels as in A. deserti. 
Flowers 40-50 mm. long: ovary fusiform, 25-80 mm. long, considerably 
exceeding the perianth: tube about 5 mm. deep: segments 5 15mm., 
much longer than the tube but only about half as long as the ovary: 
filaments inserted nearly in the throat, scarcely 80 mm. long or twice 
as long as thesegments. Capsules light brown, 15 X 35 mm., scarcely 
ez ete peeked: seeds?
