Described from small specimens raised from seed at Kew, which formed flowers 

 ■when only 4 inches high. Unfortunately no specimens were preserved, and at 

 present the plant is leafless. As the plant is described as a large floriferous shrub, 

 the cultivated specimen perhaps represents a starved form. 



149. I. setifera, Poir. Encycl. vi. 17. Perennial. Stem slender, 

 twining or trailing, the younger portions clothed with long spreading 

 bristly hairs. Leaves entire, glabrous, cordate to ovate-cordate, sub- 

 acute or blunt, 3-5 in. long, with a deep or broad open basal sinus, 

 rarely orbicular emarginate ; petiole as long as the blade. Flowers 

 solitary on short pedicels from the axils of the leaves or 2-3-nate on a 

 long peduncle, with several large ovate foliaceous bracts at the base of 

 the pedicels, which are 1-1 \ in. long. Calyx glabrous, reaching 1 in. 

 long ; sepals ovate, apex obtuse, setiferous, back prominently longi- 

 tudinally 5-veined and plicate, the two inner much smaller. Corolla 

 funnel-shaped, bright red, 2f-4 in. long. Seeds blackish, glabrous in 

 African specimens (described by Choisy I.e. as tomentoso-puberulis). —
