Thunbergia alata, Bosrr, MSS. 
Stem long, slender, twining, clothed as well as the leaves and calyx, with a 
yellowish, silky, pubescence. Leaves cordate, or cordato-hastate, acute, 
angular at the margin, particularly near the base, with five principal 
and several smaller nerves, dark green above, paler beneath ; petioles as 
long as, or longer than, the leaves, winged on both sides from the base 
to the extremity. : 
Peduncles solitary, axillary, opposite, somewhat shorter than the leaves. 
Ext. calyx of 2 large ovato-cordate, opposite, pubescent leaves ; inner 
one small, embracing the base of the germen with several short irregu- 
lar teeth or segments. Corolla large; tube subcylindrical, broader up- 
wards, not much longer than the outer calyx, deep purple, especially 
within ; limb of 5 obcordate, large spreading, yellowish-buff coloured 
segments. Stamens included within the tube *. 
This is a second new species of Thunbergia, which has 
been discovered by Messrs HetstnporG and BoJEr, and 
communicated by CHARLES TELFAIR, Esq. of the Mauritius, 
* Mr Barcray having, along with Th. alata, sent to me the fruit of Th. angulata, 
a species given at t. 166. of this work, I here figure and describe it : : 
Capsule globose, with a long acuminated beak, surrounded at the base by the persistent 
inner calyx, opening elastically, and with a considerable report, into two equal 
valves; 2-celled partition of the cells contrary to the valves, membranaceous, easily 
separating from the valves, and supporting 4 seeds, which are laterally attached, 
two on each side. Seeds half-oval, brown, convex, and wrinkled without: the inner 
side having an oblong smooth depression.
