2A. Diguetit Simon, Cat. [1900]: 15, not Weber !—Name only. 
Habit? Leaves grayish for glaucous, slightly granular-roughened, 
linear- or oblong-triangular, gradually acute, deeply concave, becom- 
ing channeled near the end, 2-4 < about 30 cm.: spine acicular, nearly 
straight, finally gray-brown, 2>< 25-30 mm., slit-grooved below, 
decurrent for scarcely its own length: prickles dull brown, graying, 
10 or 15-25 mm. apart, scarcely 3 mm. long, mammaeform or trian- 
gular, friable and easily detached, on fleshy prominences between 
which the margin is rather straight. Inflorescence 3-4 m. high, 
slender, paniculate, with the ultimate branches subracemosely fasciate, 
at first blue-waxen, much as in Negundo: pedicels thick, free for 
scarcely 5mm. Flowers yellow, 35 mm. long: ovary stout, 5 15-20 
mm., oblong, rather exceeding the perianth: tube cup-shaped, about 
8 mm. deep: segments oblong, 412-15 mm., much exceeding the 
tube and approximating the ovary in length: filaments inserted 
nearly in the throat, about 25 mm. long, and little more than twice as 
long as the segments. Capsules pyriform-oblong, thick-walled, 
glaucous, 20> 55 mm., scarcely stipitate and little beaked: seeds?

Agave carminis Trelease 
Habit? Leaves smooth, gray-green, triangular-oblong, acute, 
thick, becoming channeled near the end, about 5 < 30-40 cm.: spine 
slightly glossy, from light brown becoming rather gray, acicular, 
gently a little upcurved, 2 35 mm., slit-grooved to the middle, very 
long-decurrent; prickles similarly colored, firm, 20-30 mm. apart, 
about 5 mm. long, narrowly triangular, variously and irregularly 
curved, slightly lunately widened onto the tops of low fleshy prom- 
inences between which the margin is nearly straight. Inflorescence 
paniculate with slender scape and short ascending nearly simple 
branches at the ends of which the very short but rather thick pedicels 
are compactly clustered. Flowers and fruit?
