THUNBERGIA ALATA. 
(winged thunbergia.) 
ORDER. 
ANGIOSPERMIA. 
NATURAL order. 
ACANTHACE^. 
Generic Character. — Calyx double, outer one consisting of two heart-shaped leaflets, each having three 
nerves, inner one smaller, and toothed. Corolla consisting of one petal somewhat bell-shaped, with 
a limb divided into five spreading lobes. 
Specific Character. — A twining shrub, Stem slender, covered thickly with soft white hairs. Leaves 
heartshaped, sagittate, opposite, pubescent, five nerved. Flowers solitary, springing from the axils 
of the leaves. Calyx double, yellow-green. Corolla orange-yellow, or buff ; inside of the tube 
dark purple, giving a striking appearance to the eye. 
This beautiful plant is a native of the island of Zanzebar, in the East Indies, 
whence seeds were received by the late Mr. Barclay, of Bury Hill, in 1823, and 
in whose splendid collection it flowered for the first time in this country. 
It is a stove climbing plant, where it grows and flowers with the greatest 
luxuriance, a single plant covering a space of four feet broad by ten feet high, and 
when in full bloom it makes a gay appearance, the dark purple visible at the 
mouth of the tube, forming so conspicuous a contrast with the delicate buff colour 
of the expanded limb of the corolla. 
The best soil is light sandy loam and peat, mixed with a small portion of well 
rotted dung or leaf-mould. It is easily propagated by cuttings, which should be 
taken off when half ripened ; plant in pots of light soil mixed with sand, and 
plunge in a little heat. 
Plants raised from seeds are preferable, when seed can be obtained, for they 
grow stronger, and survive the winter better than those raised from cuttings. 
Water sparingly in the winter and spring months, until they begin to push 
vigorously. 
The plants should be regularly syringed over the leaves to check the red spider, 
to which they are very subject. Water heated to about 120 degrees Fahr. will 
kill them with greater certainty than when cold.
