GENUS. Thpnbergia. Linn^us. Calyx brevis cupuliformis, truncatus 
aut pluridentatus, dentibiis turn pliiribus quam decern. Bracte^ duae ad basin 
calycis, calyce majores eumque ante anthesin valvatim tegentes. Corolla 
campanulato-infundibuliformis, fauce inflata, limbo quinquefido patente sub- 
sequali. Stamina quatiior didynama. Antherai erecta?, adnatae, bilocellatEe, 
locellis parallelis margine ciliato-barbatis, altero basi paulo breviore ibidemque 
in calcar aristiforme producto. Stigma infundibuliforme, transverse emargin- 
atum sub-bilabiatum. Annulus nectarifer crassus, lobatus, ovarium cingens. 
Capsula ad basin globosa, bilocellata, di-tetrasjierma; superiora versus rostra- 
to-attenuata,depressa, commisura plana contigna. Dissepimentum membran- 
aceum, in centro cobserens, a valvis solubile. Retinacula nulla, quorum loco

calyx, larger than and including it. Corolla campanuIato-funneU 
shaped, throat inflated, limb five-cleft, spreading, subequal. Stamens 
four, didynamous, anthers erect, adnate, bilocular, the lobes parallel, 
coarsely ciliated, unecjual at the base, the shorter having a bristle-like 
spur. Stigma funnel-shaped, sub-bilabiate; a thick nectariferous 
lobed ring embracing the base of the germen. Capsule globular at 
the base, bilocular, two-four seeded, attenuated into a beak. Dissepi¬ 
ment membranaceous, cohering in the centre, separable from the 
valves. Retinacula wanting, and the place supplied by a cartilagi¬ 
nous ring, embracing the base of the seed. Seeds globular, perfo¬ 
rated at the base, where the podosperm enters. Flowers axillary, 
pedunculate, solitary, or in racemes. Scandent plant, with handsome 
flowers, which are blue or yellow, the throat being generally darker.
