Cult. All the species of Manéttia are worth cultivating for 
the beauty and elegance of their flowers. A mixture of loam 
peat and sand is the best soil for them. They are easily pro- 
pagated by young cuttings in the same kind of soil under a hand- 
glass, in a moderate heat.

Corolla funnel-shaped (f. 89. e.), tubular, elongated, beset with 
velvety papillae outside, with a naked throat, and a 4-parted 
spreading short limb (f. 89. d.). Stamens having the filaments
