successfully cultivated in a basket suspended from the roof of a low 
house; the hanging branches, bearing a succession of beautiful 
blossoms during the summer, make it a valuable addition to any 
collection; it should be prized especially by those who delight in 
graceful and charming basket plants. Our illustration is from a 
plant collected in Costa Rica by C. Wercklé, in 1905. 
The genus Columnea is widely distributed in tropical America, 
and more than one hundred species are known. ‘These vary con- 
siderably in habit; some have erect stems, while others, as in the 
example before us, have creeping stems with pendent branches. 
Columnea gloriosa belongs to the section Eucolumnea, and sub- 
section Macrocalyces. Eucolumnea is characterized by the usually 
small leaves, arranged in pairs, with one sometimes smaller than 
the other, and a strongly two-lipped corolla which has a narrowly 
cylindric tube, the upper lip being hood-shaped and formed of the 
four united lobes. The subsection Macrocalyces is distinguished 
primarily by the large calyx-lobes, and by the thicker hairy corolla 
with shorter tube. There are some ten or a dozen species of this 
subsection known, mostly natives of Central America, the most 
familiar species being perhaps Columnea Schiedeana Schlecht., from 
Mexico.
