The South African genus Haworthia, according to the 
recent monograph which we owe to Mr. A. Berger, in- 
cludes some three score species, and it is somewhat 
remarkable that in the case of five-sixths of the species 
_ enumerated in the ‘ Flora Capensis’ the precise habitat 
was unknown in 1896. Most of these species were intro- 
duced to cultivation in Europe towards the close of the 
18th and the beginning of the 19th Centuries, during a 
period when the growing of succulent plants was much 
in vogue. Many of these were first described by the 
late Mr. A. H. Haworth, one of the founders of the Hull 
Botanic Garden, in whose honour Mr. H. A. Duval 
named the genus to which the plant here figured belongs. 
A few of the members of this genus had been described 
by earlier authors as species of Aloe, from which, how- 
ever, J/aworthia, as understood by Duval, differs in 
having a perianth with an oblong tube and a bilabiate
