Calyx 5- rarely 6-partite, equalling or shorter than the corolla-tube. 
Corolla-tube narrow or wide, urceolate or cylindrical, terete or 9- 
gonous, limb 5-6-fid, seements usually spreading. Stamens 10-12, 
inserted on the corolla-tube, filaments filiform, short or elongated ; 
anthers oblong, exserted or included. Squamule linear, oblong or 
square, sometimes broader than long. Carpels 5—6, free, attenuated into 
filiform or subulate often exserted styles, with obliquely capitellate 
stigmas ; ovulesmany. Follicles many-seeded.—Herbaceous or shrubby, 
branched or scapigerous, varying much in habit. Leaves opposite or 
alternate, sessile or petiolate, often very thick and fleshy, rarely peltate, 
sparse or rosulate. Flowers erect or pendulous, varying in size, race- 
mose or cymose, often showy. Corolla-lobes twisted in wstivation. 
A genus of about 70 species, occurring in West and South Europe, throughout 
Africa especially at the Cape, in Eastern Asia, the Himalayas, and Mexico.
