Wislizenus ; Karwinski, Poselger. FI. in May.—I have ventured 
to unite the different forms under the oldest (Zuccarini’s) name, 
the more so, as I was able to compare the original specimen in the 
Munich botanical garden, where I found it in flower in August, 
1869. Whether several other garden-forms, described under dif¬ 
ferent names, all characterized by soluble corneous leaf-edges, 
belong here, or constitute distinct species, can be decided only 
when their flowers become known. Zuccarini’s typical speci¬ 
men has leaves 18 inches long and 2\ inches wide, with a spine 
1 i inches long, the spiny teeth straight or curved up or down, 
whence the specific name ; scape 6 feet high ; flowers only 1 inch 
long (ovary 5, perigon 7* tube over 1?, filaments 15 lines long 
from base of tube) ; no fruit was matured, but many bulbilli were 
sprouting from the top of the scape. Gen. Jacobi (Ag. app. p. 14) 
•describes a specimen which flowered at Brussels with perigon 
•divided to the base, most probably inaccurate, as no Agave is 
known with such a flower. 
Our plant grows in mountainous and rocky localities, is called 
Lechuguilla (“Lecheguilla” in the Mex. Bound. Bot. is a mis¬ 
print), and its rootstock Am ole ; the leaves furnish excellent but 
rather coarse fibre, and the rootstock is used as soap and is a 
“ savory food” when roasted ; trunk 4-6 inches high ; leaves (be¬ 
fore me) 10-20 inches long and 1-1J inches wide, margin and its 
teeth dark red-brown, at last fading to ash-color and becoming 
detached from the leaf, but adhering long to the terminal spine; 
teeth 9-12 or 15 lines apart, below smaller and straight, upward 
larger (15-2 or even 3 lines long) and strongly uncinate, not irre¬ 
gular, as in the original specimen ; terminal spine 7-9 lines long, 
slightly grooved on lower third or fourth. Scape 6-10 feet high, 
its bracts from 2 inches down to 1 inch long, deciduous, so that 
in the flowering spike little of them is seen. The flowers before 
me indicate two forms, one with a slender ovary, 7-9 lines long,
