A large twining, branched, milky shrub, the young shoots strigose. 

 Leaves alternate, on long petioles, which are round, and furnished at 

 the base with 2 thick oblong glands ; limb broadly cordate-ovate, rather 

 acute, entire, glabrous, dark shining green above, beneath strigosely 

 hirsute, and somewhat silky. Peduncles axillary, rather longer than 

 the petioles, dividing at the extremity into 2 or 3 branches, with a sessile 

 ebracteated flower in the fork ; each branch divides again in the same 

 manner : the solitary flower in the second and all succeeding divisions 

 furnished with a long, lanceolate, waved, pale green, hairy bractea. In 

 this manner, what was at first an umbel, progressively becomes a panicle, 

 bearing flowers and fruit in all stages, each of the pedicelled flowers 

 having 3 bracteas closely appressed to the base of the calyx. Calyx of 

 5 ovate and mucronate hairy sepals. Corolla campanulate, externally 

 hairy, of a purplish-white colour; within, near the bottom, deep-purple, 

 becoming paler near the throat : limb spreading, cream-coloured. 

 Stamens 5; filaments unequal, enlarged at the base. Ovary superior, 

 seated in a yellow glandular cup-shaped disk. Style as long as the 

 stamens. Stigma 2-lobed, Pericarp a 3- to 4-seeded berry, deep 

 orange-coloured when ripe. Seeds imbedded in pulp. Wight and Amotl. 

 — Decoctions of the leaves are used by the natives as fomentations in 

 cases of scrophulous enlargements of the joints; the boiled leaves 

 being employed as a poultice at the same time. Juice milky. Wight. 



IPOIVLEA.
