Cult. The species of this genus are very different in habit 
from the rest of the genera of the present order, from the 
branches being woody and furnished with proper leaves; but 
the flowers resemble the other genera of the order. They are 
of easy culture, growing freely in any light earth; and cuttings 
of them are readily rooted in mould or sand, under a hand- 
glass, in heat. A large plant of any of the species has a very 
grotesque and ornamental appearance, when several species of 
Cereus and Epiphyllum has been grafted or inserted on it. 
Very like the preceding
