A peculiar mor- phology and life-history is found in Streptocarpus (). Us- sol. or in cymose infls. of various types, ? , usu. markedly •[•. K (5), us>u. with very stout teeth, generally valvate; C (5), often 2-lipped, imhr. (in Kamondia, &c. it is nearly rotate and reg.); A usu. 4, didyna- mous, or 2, or 5 (Ramondia, &c.), alt. with corolla lobes; stds. often found. At the base of the flower-tube is a dic, whose various shapes form important marks in distinguishing gen. ; it may be ring-shaped (thin or thick), 5-angled, 5-lobed, or re- duced to 5 or fewer glands. G sup., or ± inf. (see below); always (2), i-loc. with parietal plac. which sometimes project inwards so far that it becomes imperfectly 2-loc. ; ovules oo, anatr. ; style simple ; stigma often bilobed. Fr. usu. a caps , splitting loculic. into 2 valves, each of which may again split into 2 ; sometimes (Ramondia) the caps, is septicidal, or opens only at the tip, or the fr. may be ± fleshy or berry-like. Seeds small and numerous, with endosperm (§ II) or without (most of § i). Embryo straight. Fls. mostly protandrous; their large size and bright colours suit them to insects. Saintpaulia (</.».), Klugia, and others exhibit two types of symmetry on the same plant, the fls. (and usu. the 1.) on the left side of the infl. being like the reflections of those on the right (enantiostyly). Germin. interesting, Streptocarpus ( ). The cots, are epigeal, and usu. thin, one larger than the other and often growing subsequently to some size: buds are often found in their axils. Anisophylly is very common, and usu. alt. on one side and the other. None of the G. are economic plants; many are hothouse tavourites. Classification a
