toothed, sometimes with outer bracts seated close to 
the sepals. Corolla monopetalous, hypogynous, two- 
lipped ; upper lip emarginate, lower divided into three 
or four lobes. Stamens four, inserted in the tube of the 
corolla. Anthers two-lobed or two-celled. Ovary two- 
celled. Style simple. Stigma undivided. 
Specific Character. — Perennial. Stems round; 
leaves opposite, ovate, notched. Flowers tubuli 
violet-purple. Calyx five narrow green segmen

This desirable perennial has been lately introduced into our gardens froi 
China, by Mr. Fortune, who “ found it growing on hill sides and near streams : 
the Island of Hong-Kong.' ! It is of easy cultivation, and will grow freely in any lig 
soil where it has good drainage. Usually it has been grown in a pot as a sto 1 
plant, but it will probably be found to thrive much better in the greenhouse, 
grows eighteen inches or more high ; and although not very showy, is yet w( 
deserving of cultivation. Its situation in the house should be one where it is n 
too much exposed to bright sunshine, as it seldom thrives under those circur 
stances. Increase by division of the roots and by seeds. 
The plant from which our drawing was taken flowered in the stove of G. Terrain 
Esq., Wallington Lodge, Carshalton, Surrey. 
The generic name is given in allusion to the singular form of the stigma, (whit 
ends in a thin broad plate, curving forwards, and forming a stigma on its anteri 
edge,) from pteron, a wing, and stigma , a point.
