PERESKIA. 



II 



densely branched bush, but is sometimes grown as a climber, 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 purplish 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.

In this series we include 18 species, all tropical American, both continental and insular.
