Flora of the Malayan Peninsula. 
lobed or -partite, lobes usually persistent in fruit, valvate or imbricate 
in bud. Corolla gamopetalous, tubular, rotate or campanulate, superior, 
sometimes bilabiate ; lobes as many as those of the calyx, valvate or 
induplicate-valvate, sometimes 1, 2, or all free to the base. Stamens 
equal in number to the corolla-lobes and alternate with them ; inserted 
on the epig'ynous disk or (in Sphenoclea) on the corolla-tube ; filaments 
free or connate in a tube ; anthers linear, oblong or ovate, free or 
connate in a tube, 2-celled, the cells parallel, dehiscing longitudinally and 
introrsely. Ovary usually inferior, 2-5- rarely more-celled ; placentas 
axile, many ovuled; style simple, clavate, within the staminal tube; 
stigma-lobes as many as the ovary-cells ; ovules anatropous, erect 
horizontal or pendulous. Fruit capsular or baccate, crowned by the 
persistent calyx-lobes, dehiscing vertically or laterally, or indehiscent. 
Seeds very many, small, albuminous ; testa thin, coriaceous ; embryo^ 
erect, radicle inferior. — Distrib. Over 1,000 species, scattered 
throughout the globe, chiefly in temperate regions.
