L. Spec. Plant. I, p. 311. — Stem slender, twining, shortly hairy, or 
pubescent along two lines or all round, Leaves spreading, thin; 
petiole 1—2,5 cm long, pubescent; blade 27/,—6 cm long, 1 to 
21/, em broad, elongate-ovate or oblong-lanceolate, acuminate, cor- 
date at the base, both sides nearly glabrous, ciliolate. Flowers 
numerous, in short umbel-like racemes; peduncles 1—5 cm long, 
pubescent or shortly hairy; bracts 2-—6 mm long, subulate or fili- 
form, pubescent; pedicels 5—10 mm long, pubescent. Sepals 21/, to 
5 mm long, ovate or lanceolate, acute, pubescent. Corolla 1—2 cm 
in diam., rotate; lobes 51/,—8 mm long, 2—21/, mm broad, lanceo- 
late-attenuate, obtuse, with a scattered pubescence on the back, 
puberulous within. Corona tubular, toothed at the top, arising near 
the base of the staminal-column; tube 2—-27/, mm long, principal 
teeth 5, filiform or subulate, 5—5'/, mm long, with 5 short exce- 
edingly variable lobes alternating with them, these are subulate, 
tapering from the base or deltoid-ovate or abruptly contracted into 
a short linear recurved tooth, or 3—4-denticulate; within the tube 
are 5 other filiform or subulate teeth with ovate or deltoid bases, 
1,—*/, as long as the long teeth in front of which they arise. 
Staminal-column scarcely as long as the coronal-tube; anther-appen- 
dages broadly ovate, obtuse, inflexed or connivent over the convex
