Beautiful specimens of this plant, together with the charm- 
ing drawing by Dr Greville (which is here engraved) were 
communicated to me in the month of December last (1825) by 
Dr Graham, from the stove of the Royal Botanic Garden of 
Edinburgh. The seeds were received from the Calcutta Bo- 
tanic Garden, but without any history of the plant ; and the 
only description hitherto published, is that by Dr Graham 
himself in the Edinburgh Philosophical Journal above quoted, 
from which excellent account I have compiled much of that 
here given. 
This is by far the most showy species of the genus we 
know, the brilliant red flowers of the graceful racemes forming 
a fine contrast with the delicate green of the leaves. The other 
hitherto known species of Thunbergia have solitary and axil- 
lary flowers, and a distinctly two-leaved outer calyx. In the 
structure of its calyx, our plant approaches the Thunbergia 
grandiflora of Dr Roxburgh, and Bot. Reg. t. 495.
