distinctly elevated, the edge scabrous, with minute denticulation. Scape 
none, or very short. Flowers in a close, oblong panicle, 9-12 inches . 
long, by about half as broad, with very numerous ascending branches, 
into a flat anceolate base; lower branchlets copiously panicled; 
the flowers moderately close. Pedicels sometimes as long as the perianth, 
in hyaline lanceolate, as long as the pedicels. Stamens 
the base and apex, very membranous, breaking away and leaving the 
usually solitary globose pea-like seed exposed.

and C. Wright, 693; in New Mexico by Bigelow, and in Sonora 
by Schott. Not now in cultivation. Trunk reaching a height of 
4-5 feet. Leaves like those of B. Hartwegiana in shape, size, and 
blade not so thick and rigid in texture and nea ly flat on both sides, 
narrowed to an entire point, the edge distinctly serrulate, the lower part 
with 10-12 distinct veins. Scape 1-2 feet long, bracteated with 3—4 
lacerated, usually shorter than the pedicels. Capsule 4 lines each way, 
emarginate at both ends, thin and membranous, the angles conspicuously 
long.
