(white- FLOWERED 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, 
v/ith a limb divided into five equal lobes. 
Specific Character. — A twining shrub. Stem slender, covered thickly with soft white hairs. Leaves 
heart-shaped, sagittate, opposite, pubescent, five-nerved. Flowers solitary, springing from the axils of 
the leaves. Ca/j/c*" double, yellow green. Corolla 0X2MgQ yellower buff; inside of the tube dark 
purple, giving a striking appearance to the eye. 
Var Alba. — Habit very like the alata, but with broader leaves, and larger flowers, its beautiful deliQate 
Avhite corolla, and the conspicuous dark spot in the centre. 
This beautiful and interesting- plant has so striking a resemblance to Thunhergia 
alata, in every important particular, except the colour of the corolla, that we are 
lead to consider it merely a variety of that species. 
It is unquestionably a most desirable plant, being so vi^ell adapted for training 
up the rafters of the stove, or other convenient places, where its loveliness can be 
clearly seen. 
It grows freely, and produces its blossoms in great abundance, and no doubt 
will be found to propagate with great ease. For further particulars see Vol. IL 
page 2, where T. alata is treated of. 
We are obliged to Mrs. Lawrence, of Ealing, for our drawing, in whose collection 
the plant flowered beautifully in the early part of last summer. 
The generic name is given in honour of Charles Peter Thunberg, M. D., Pro- 
fessor of Botany in the University of Upsal.
