Description
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]
