CHAP. Jor 
OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER FICOIDA‘CEX, 
OR MESEMBRYA‘CEX. 
Mesembryinthemum L. There are a great many species and varieties of this genus described by 
botanists, no fewer than 339 being enumerated in Don’s Miller. Most of them are natives of dry 
sandy soils at the Cape of Good Hope, and in other parts of Africa ; and many sorts will live through 
the winter on rockwork, in the neighbourhood of London, if protected with dry litter. When they 
can be preserved through the winter, they make a splendid appearance in the summer, with their 
brilliant flowers of scarlet, yellow, purple, or white. Several species have stood through the winter, 
without any protection, on the rockwork in the Chelsea Botanic Garden ; and a number of sorts 
were, till lately, preserved in a cold-pit in the garden of the London Horticultural Society.
