Cult. All the species of Manettia 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.

LIN. SYST. Tetrandria, Monogynia. Calyx with a subglobose 

 tube (f. 89. a.), and a 4-parted limb (f. 89. 6.) ; lobes linear- 

 subulate (f. 89. 6.), sometimes with a tooth between each lobe. 

 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. rf.). Stamens having the filaments 

 adnate to the tube at the base, and free from about the middle 

 (f. 89. e.) ; anthers linear, inclosed. Stigma bilamellate (f. 89. 

 g.), exserted. Superior part of the ovarium naked. Capsule 

 membranaceous, globose, a little compressed, 2-celled, and 

 dehiscing at the cells above ; valves semi-septiferous. Pla- 

 centas orbicular. Seeds many in each cell, compressed, imbri- 

 cated downwards according to the figure of Salisbury, but up- 

 wards according to the figure in fl. mex., girded by a membra- 

 nous wing. Shrubs, natives of Mexico. Leaves opposite or in 

 whorles. Stipulas narrow, acute, adnate to the petioles on both
