Generic Character. — See Vol. 3, page 50. 
Specific Character. — Plant herbaceous, with smooth, twining, roundish branches. Leaves alternate, 
palish green, acuminate, entire, undulated, veined. Footstalks the length of the leaves. Flower- 
stalks somewhat racemose, axillary, producing three or four flowers. Calyx five-parted, small, 
erect, of a brownish puiple colour, with a pale, nearly white margin. Corolla^ before expanded, 
white, with the limb of a rich red, which when fully developed assumes a fine purplish blue, with 
five angles. Filaments unequal, arising from the base of the tube. Anthers oblong, yellow. 
Germen oblong. Style filiform. Stigma two-lobed. 
The seeds of this splendid plant were collected by Mr. Samuel Richardson, 
(an officer in the Anglo-Mexican Mining Association,) in the province of Guanax- 
uato in Mexico, by whom they were presented to I. D. Powles, Esq., of Stamford 
Hill. 
In the stove, about the months of July and August, this plant makes a very 
pretty show when trained up the rafters, or other parts of the house where it can 
be clearly seen. It flowers freely, and will grow well in soil composed of equal 
portions of loam and peat, with a little well-rotted dung. 
About the middle of October last, we were favoured with the sample from 
which our drawing was made, by Mr. Cameron, Curator of the Birmingham Botanic 
Garden, where it flowered profusely in the stove. 
Although it has been considered to flower only in the stove, there is no doubt 
but it would produce abundance of blossoms in a sheltered situation, against a 
south wall, in the open air, especially if the wall is flued.
