About the year 1846, we received from Mr. Repper, of the 
Real del Monte Company’s establishment, Mexico, some re- 
markable plants.in the form of tubers, a foot and half long, and 
nearly as high aboveground, the surface of which is formed by 
a number of wrinkled tubercles, slightly elevated, and somewhat 
circinately wrinkled ; from a few of which appeared tufts of rigid, 
subulate leaves, one to two feet long, in form and texture resem- 
bling those of some Dasylirium. The general aspect of the tubers 
reminded one of the well-known “ Elephant’s-foot” of South 
Africa, or of some remarkable Dioscoree which we cultivate from 
Mexico. These remained dormant for some years, but one of 
them has lately produced more copious tufts of foliage and panicles 
of flowers ; and precisely accord (the female flowers are however 
wanting to our plants) with the Dasylirium Hartwegianum of 
Zuccarini, which Hartweg sent from Zacatecas, in Mexico ; and 
a Dasylirium of Mr. Charles Wright (“ Coll. N. Mex. 1851-2”), 
n. 1918, also seems to be identical; but neither of these collec- 
tors has made a note on the nature of the plant ; so that whether
