 Cape ; the fourth is common to the tropics of both hemispheres. 



1. B. calycinum, Salisb. ; DC. Prod. iii. 396. Shrubby, 2-4 ft. 

 high, branched from the base, glabrous throughout. Barren stems 

 ascending ; flowering stems erect, cylindrical, spotted with dark purple. 

 Leaves fleshy, crenate, ovate orbicular, or unequally pinnate with ovate 

 segments, the terminal one larger than the rest. Flowers 1J— 2 in. 

 long, pendulous. Calyx inflated, 1-1 \ in. long, green, striped with 

 purple at the base. Corolla-tube green below, bright reddish-purple in 

 the exserted portion, globose-octagonous at the base, abruptly con- 

 stricted immediately above, then produced into an elongated, 4-angled, 

 ventricose tube ; limb 4-fid, segments abruptly acuminate, very acute, 

 spreading. Stamens slightly exceeding the corolla-tube. Styles 

 equalling the stamens, erect, filiform. Stigmas sparingly papillose. 

 Squamuke truncate, short, nearly as broad as long, free, or very slightly 

 adhering to the carpels. — Bot. Mag. t. 1409.

Calyx 4-partite, rarely 4-fid, segments linear-ovate or subulate, 

 shorter than the corolla-tube, usually deciduous. Corolla hypocrateri- 

 form, tube usually urceolate, limb 4-partite, spreading (except in 

 K. humilis), persistent. Stamens 8, adnate to the corolla-tube, in two 

 series, all antheriferous, filaments rather short; anthers oblong, in- 

 cluded. Squamulae 4, linear or oblong. Carpels of the ovary 4, adnate 

 to the base of the corolla-tube (except in K. humilis), lanceolate, nar- 

 rowed into slender styles with obliquely truncate stigmas; ovules 

 many, multiseriate. Follicles membranaceous, many-seeded. — Robust 

 erect herbs or shrubs. Leaves fleshy, opposite, sessile or petiolate, 

 entire crenate or pinnatifid. Flowers rather large, usually in many- 

 flowered paniculate cymes, yellow purple or scarlet. 



A genus of about thirty species, having its head-quarters in Tropical Africa, but also 

 represented at the Cape, in Tropical Asia, and in Brazil.
