II-' Geminiflor^e. 
Flores e bractearum axillis bini oppositi, dense spicati. 
The species appertaining to this section, 40 or 50 in the books J 
4 of which belong to our Flora, are usually stouter, sometime^ 
with a short trunk, leaves rarely soft and almost herbaceous, but: 
perhaps always perennial, often tough and sometimes the tough-j 
est in the whole genus ; their margin is most variable, entire, of 
with small pale cartilaginous teeth, or filamentose, or with stout,! 
horny, brown spines. — Together with the first section they con¬ 
stitute the Agaves spicatce of some authors; others, who have ■ ■ 
principally regarded the growth and foliage of cultivated plants,! 
have scattered them in various groups, niixed with the species! 
of the next section.

Saltillo, Buena Vista, and apparently all over that northern! 
part of Mexico, abundantly collected by Drs. Wislizenus and! 
Gregg in 1846-48 ; flowering in the, latter part of May, and again ! 
in July and August, probably at different seasons, as many Mexi-j 
can plants do, stimulated to development by a few rains or even *j 
a single heavy one. —As the plant is common in a region often 4 
traversed by collectors, it seems strange that it should not have; 1 
become known and been brought into cultivation long since ; but! 
I can find no description^ which I might refer here, unless it bq! 
/ the A. Californica , Hort. Kew^of which I find a notice in Jaco-j 
bi’s Agave, App. p. 47 ; but I strongly suspect that this refers tq 9 
no Agave at all, but to Yucca Whipplei .
