The fact that Cacti are sufficiently hardy to bear English 
winters has long been known, and is set forth in this work 
when figuring Opuntia vulgaris (Cactus Opuntia, t. 2398), 
but it is comparatively of late that their cultivation in 
the open air with protection from damp only in the winter 
months has been successfully pursued to any extent; and 
when the number of large and-brilliantly flowered species 
that inhabit countries to which such treatment in England 
is well adapted is considered, a very great development of 
this branch of Horticulture is to be anticipated. O. Ra- 
Jinesquii has a wide range in North America, from Wisconsin 
in the north and Kentucky in the east, and probably to 
Louisiana and Texas in the south and west. For a full
