The species, according to Jacquin, come* from the pro- 

 vince of Caraccas in South America. In the plant that 

 flowered at Vienna, the panicles were short and the pe- 

 duncles generally triehotomous and 3-flowered, in Mr. Cat- 

 ley's plant the panicle was long, but the two side flowers 

 on each peduncle were almost always abortive, and the 

 main peduncle had no side branches like the specimen 

 figured in Jacquin's work. 



A high climbing shrub: branches round, roughened, as 

 well as the main petioles and peduncles, with ferruginously 

 coloured excrescences. Leaves opposite, conjugate, cir- 

 rhose: main petiole thick firm round an inch long; partial 

 ones smooth half an inch long: leaflets ovate or ovately lan- 

 ceolate, entire, pointed, veiny, firm and slightly coriaceous, 

 deep green and bright above, paler underneath and ribbed, 

 from 6 inches to a foot and a half long, 4-9 inches broad : 

 tendril simple strong, at the back of the apex of the main 

 petiole, (this is sometimes converted into a leaflet, when the 

 leaf becomes ternate, instead of conjugate and eirrhose.) Pa- 

 nicles terminal between two leaves, generally in threes or 

 triehotomous, the middle much the largest, with 3-flowered 

 peduncles: bractes single linear subulate, one to every pe- 

 dicle. Calyx short and tubular, obsoletely 5-toothed, green, 

 sometimes suffused with purple, cleft on one side. Corolla 

 deep yellow, nearly 3 inches long, smooth, without scent : 

 tube very short, constricted above the calyx, having a 

 shaggy ring on the inside at the mouth where the stamens 

 are inserted: faux very long, much wider, compressed; 

 limb bilabiate, widespread; segments roundish, equal, 3 

 lower subundulate, middlemost of these crenate. The fifth 

 stamen, a mere rudiment. Germen stalked, standing on a 

 circular fleshy disk. 



We have trusted chiefly to Jacquin for the description 

 of the species ; having missed the opportunity of inspecting 

 the fresh blossom.
