This very distinct species of Agave, long cultivated in the 
Royal Gardens of Kew, but whose native country is hitherto 
unrecorded, was received by us from the Rio del Monte district, 
Mexico, and is remarkable for the great length of the flower- 
stem or scape in proportion to the rest of the plant,—so tall, 
that long before the flowers began to expand, we were obliged 
to remove the plant from a greenhouse fifteen feet high to a 
loftier building, and support the continually elongating scape 
against the wall. The flowers did not expand till this had at- 
tained a height of twenty feet. The distance of the flowers from 
the spectator renders them inconspicuous ; but when more closely 
inspected, they are by no means insignificantly small, of a bright 
yellow-green, with much exserted yellow large stamens, ‘whose 
filaments and anthers are partially tinged with red. Its flowers 
are produced in a cool greenhouse, in the summer months. 
Descr. Stem or caudex in our plant short, erect, about two 
to three inches thick, scarred with the persistent bases of fallen 
foliage. Leaves numerous, outer and older ones curved, inner 
and younger ones more erect, one to one and a half foot long, 
nearly two inches wide in the broadest part, lorato-acuminate, 
coriaceo-carnose, glaucous, canaliculato-concave above, very ob-
