SCROPHULARIACEiE. 
Generic Character.— Calyx five-parted or five- 
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 tubular, 
violet-purple. Calyx five narrow green segments, 
having three bracts seated immediately outside of 
them, broader than the segments of the calyx. Corolla 
two-lipped ; upper lip broad, and notched in the 
middle, lower lip divided into three segments. Stamens 
only two, fertile. 
This desirable perennial has been lately introduced into our gardens from 
China, by Mr. Fortune, who " found it growing on hill sides and near streams in 
the Island of Hong-Kong." It is of easy cultivation, and will grow freely in any light 
soil where it has good drainage. Usually it has been grown in a pot as a stove 
plant, but it will probably be found to thrive much better in the greenhouse. It 
grows eighteen inches or more high ; and although not very showy, is yet well 
deserving of cultivation. Its situation in the house should be one where it is not 
too much exposed to bright sunshine, as it seldom thrives under those circum- 
stances. Increase by division of the roots and by seeds. 
The plant from which our drawing was taken flowered in the stove of G. Lorraine, 
Esq., Wallington Lodge, Carshalton, Surrey. 
The generic name is given in allusion to the singular form of the stigma, (which 
ends in a thin broad plate, curving forwards, and forming a stigma on its anterior 
edge,) from pteron, a wing, and stigmata point.
