Thunbergia angulata, Helsinboro et Boyer, MSS. 
A slender, graceful climbing plant, with glabrous stems and altogether the 
habit of Maurandia antirrhinifolia. Leaves upon footstalks longer than 
themselves, opposite, broadly cordate, glabrous, somewhat acuminated, 
angulated at the base, with three principal and several smaller branch- 
ing and anastomosing nerves. The bases of the petioles are connected 
by a short ciliated pair of stipules. 
Flowers axillary, solitary, opposite, upon long peduncles. Exterior calyx of 
2 rather large, ovate, opposite, appressed, 1 -nerved leaflets, ciliated on 
the nerve and at the margins. Inner calyx small, of one piece, with 
many nearly equal, short linear segments. Corolla nearly thrice as long 
as the outer calyx, about an inch long, rather tubular than campanu- 
late : tube swelling on the under side near the middle : the mouth open, 
the limb cut into 5 shortish, obtusely rounded, spreading, or even re- 
curved segments. Stamens included. Anthers large, sagittate, 2-celled, 
their margins fringed with long hairs. Germen ovate. Style longer 
than the anthers. Stigma bilabiate *. 
Whilst the Continent boasts of her magnificent public in- 
stitutions, endowed and supported by the governments of the 
various countries to which they belong, it is the peculiar boast 
of Britain that so much is here done by the liberality and zeal 
of private individuals. What is so often said of the collections 
in the fine arts of this country, may with equal truth be as- 
" The capsule of this plant will be found figured and described at t. 177. of this 
work, under Th. alata.
