Description of the Variety, Thunbergia alata-clorantha. 
Stem twining, branched, hairy, compressed, hairs loosely reflexed. 
Leaves (two-and-half inches long, one-and-half broad) smaller up¬ 
wards, petiolate, sagettato- deltoid, sinuated, pubescent on both sides, 
wrinkled, dark green above, paler below, midrib and veins channelled 
above, prominent below; petiole as long as the leaf, bordered with a 
narrow waved wing. Peduncles solitary, axillary, opposite, single 
flowered. Bracts coherent to about a quarter of their length on the 
lower side, rather more above, waved and pubescent. Calyx a small 
many-tootiled cup, pale green, and pubescent. Corolla small, outside 
slightly glanduloso-pubescent; tube narrow, sub-cylindrical, and dark 
purple for about three times the length of the calyx, above this 
enlarged, compressed, paler and more leaden coloured, slightly falcate; 
limb orange-coloured, of five sub-linear emarginate lobes, concave, 
and tipped on the outer surface with green ; faux deep purple, and, as 
well as the upper part of the inside of the tube, clothed with short 
purple hairs, two broad hairy lines extend from this along the inner 
side of the back of the tube, to the top of the narrow portion of the 
tube where the hairs are numerous, around the origin of the stamens; 
hairs jointed. Stamens subequal, filaments glabrous, green. An¬ 
thers yellow, cells unequal, the shorter cells in all the four stamens, 
spurred at the base, bursting along the front, and there ciliated. Stig¬ 
ma bilabiate, concave, the lower lip the shortest and broadest. Style 
straight, glabrous, much longer than the stamens. Germen bilocular, 
seated on a yellow disk, dark green, glabrous, compressed, sand-glass¬ 
shaped, the lower portion the largest, the upper nearly solid, each cell 
of the lower portion containing two ovules. 
Popular and Geographical Notice. Nees von Esenbeck 
subdivides this genus, in the work quoted above, and describes several 
species not before published. He doubts whether this should not, 
Thunbergia angulata, Hooker, and Thunbergia tomentosa. Wall, be 
removed from Thunbergia. The varieties of this species in point 
of colour, are now very numerous in our stoves. The one now 
figured diflers materially from any of them, but 1 doubt whether it 
will be permanent. 
Introduction; Where grown; Culture. I have only seen 
this form in the nursery garden of Mr. Cunningham, Comely Bank, 
Edinburgh. It succeeds best in the stove, but I have seen it in flower 
in the open air, though of much smaller beauty. Grah.
