Family Gesneriaceae

Herbs, shrubs , or rarely trees . Leaves opposite or rarely alternate, whorled or basal, rosette forming; exstipulate ; usually simple , rarely shallowly to deeply lobed , pinnately or rarely palmately veined. Inflorescences usually cymes, rarely racemes , axillary , often near apex and appearing terminal ; usually pedunculate . Flowers perfect , zygomorphic, seldom actinomorphic . Calyx actinomorphic, rarely zygomorphic; usually (4 or) 5-divided. Corolla gamopetalous, zygomorphic, rarely actinomorphic; usually 2-lipped. Fertile stamens 2 or 4, then often didynamous , rarely 5, epipetalous ; anthers free or coherent, thecae 2, parallel, divergent, or divaricate ; staminodes 1-3 or absent. Disc ringlike to cupular, rarely absent. Ovary superior in all Old World taxa [half inferior, or inferior], 1-loculed; gynophore seldom present; placentas (1 or) 2, parietal , rarely 2-loculed, placenta 1 per locule and axile ; ovules numerous , anatropous . Style 1; stigmas 1 or 2. Fruit usually capsular , loculicidal, septicidal , or circumscissile, rarely a berry, indehiscent. Seeds numerous, fusiform to ellipsoid or ovoid , minute, sometimes with appendages at 1 or both ends, with or without endosperm; embryo straight, cotyledons equal or unequal after germination.

About 133 genera and 3000 species: Africa, Central and South America, E and S Asia, S Europe, Oceania; 56 genera (25 endemic) and 442 species (354 endemic) in China.

A few foreign well-known ornamental species are cultivated in China, including the florist's gloxinia, Sinningia speciosa (Loddiges) Hiern, and African violet, Saintpaulia ionantha Wendland.

The two ovary carpels may each produce a stigma; these stigmas are fused into a single structure. Some students of Gesneriaceae have considered the stigma to be single and either simple (capitate) or 2-lobed, whereas others consider each of the two stigmas as units . We have maintained the latter usage , but a family-wide investigation of stigma development is needed. The distinction can be blurred, however, because the stigmas may be completely fused into one with a capitate apex (as in Didymocarpus) or one of the two carpels or stigmas may be aborted resulting in a single stigma that may or may not be 2-lobed.[1]

Genus Cyrtandra

Herbs, shrubs , or seldom small trees , perennial , terrestrial , not rhizomatous . Stems branched or simple . Leaves usually few, along stem, opposite, whorled , or rarely alternate, equal to subequal in a pair; leaf blade glabrous to densely pubescent , pilose , villous , or sericeous , base attenuate to cuneate, rarely to cordate. Inflorescences lax or dense, axillary or rarely cauliflorous , 1- to many-flowered cymes; bracts 2 or absent, opposite. Calyx actinomorphic or zygomorphic; 2-5(or 6) -lobed; lobes equal to unequal. Corolla white to yellow, occasionally green, orange, reddish, or purplish, zygomorphic or rarely actinomorphic, inside glabrous to pubescent; tube campanulate to salverform , funnelform , or cylindric , not swollen, usually much longer than limb; limb usually 2-lipped; adaxial lip 2-lobed, shorter than to slightly exceeding abaxial lip; abaxial lip 3-lobed, lobes equal or central lobe longer, apex rounded or obtuse , rarely acute. Stamens 2, adnate to abaxial side of corolla tube near middle , usually included ; anthers basifixed to dorsifixed , coherent or free , thecae slightly divergent to divergent, confluent or not, dehiscing longitudinally; connective not projecting or apiculate ; staminodes 2 or 3, adnate to adaxial side of corolla tube. Disc ringlike or rarely cupular. Ovary ovoid to oblong , 1-loculed; placentas 2, parietal , projecting inward, 2-cleft. Stigma 1, terminal , capitate to ovoid or obtriangular, undivided or sometimes 2-lobed. Berry fleshy to leathery, ovoid to oblong, slightly longer to shorter than calyx, indehiscent. Seeds unappendaged.

About 350-600 species: SE Asia, Pacific Islands; one species in China.[2]
