PERESKIA. 



densely branched bush, but is sometimes grown as a chmber, as a basket plant, or in the form 

 of a pyramid. It is especially distinguished by the rich coloration of the leaves, which are 

 variously mottled or blotched above with crimson, apricot-yellow, and green, but of a 

 uniform purphsh crimson beneath. We have seen this form in the New York Botanical 

 Garden, where it is grown only as a bush. It was exhibited first at Ghent, Belgium, in 

 1908, and is supposed to have originated in Queensland, Australia.
