'''''Sinningia''''' ({{pron-en|sɨˈnɪndʒiə}})<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is a genus of [[flowering plant]]s in the family [[Gesneriaceae]]. There are about 65 species of [[tuberous]] [[perennial plant|perennial]] [[herb]]s, all occurring in [[Central America]] and [[South America]], with the greatest concentration of species occurring in southern [[Brazil]]. The best-known species, ''[[Sinningia speciosa]]'', was originally introduced to cultivation as ''Gloxinia speciosa'' and is still commonly known to gardeners and in the horticultural trade as "gloxinia". The true genus ''[[Gloxinia (genus)|Gloxinia]]'' is distinguished by having scaly [[rhizomes]] rather than tubers. ''Sinningia'' species often grow on rocks or cliffs and most are pollinated by [[hummingbirds]] or [[bees]] but ''Sinningia brasiliensis'' is [[bat]]-pollinated, and ''Sinningia tubiflora'', with large, powerfully fragrant tubular white flowers, is apparently pollinated by [[sphinx moth]]s. Most of the species have large, brightly colored flowers because of this, numerous species and a large number of hybrids and cultivars are cultivated as [[houseplants]]. Some species with particularly large tubers are cultivated by [[cactus]] and [[succulent]] enthusiasts as [[caudiciforms]]. One such example is ''[[Sinningia leucotricha]]'', often listed under the older name ''Rechsteineria leucotricha'' and dubbed "Brazilian edelweiss" for its covering of silvery, silky hairs. Other species with large tubers are ''[[Sinningia iarae]]'', ''[[Sinningia lineata]]'', and ''[[Sinningia macropoda]].'' {{Inc| Sinningia (for Wilhelm Sinning, gardener at the University of Bonn). Including Dolichodeira, Ligeria, and Rosanowia. Gesneriaceae. Tropical herbs with handsome tubular flowers, of glasshouse culture; includes the florists' gloxinia. Pubescent or villous, from a tuberous rhizome: lvs. opposite, usually large, petioled; the floral ones reduced to bracts: fls. usually large, solitary or fascicled in the axils, pedicelled; calyx-tube shortly and broadly turbinate, adnate, 5-angled or 5-winged, the limb foliaceous, broadly 5-cleft or -parted; corolla-tube nearly equal at the base or the posterior gibbous, long or broadly cylindrical, the upper part swollen or bell-shaped; lobes 5, spreading, or the 2 posterior smaller; stamens included, attached to the tube of the corolla; anthers broad, the cells confluent at the apex; glands of the disk 5, distinct, or the 2 posterior more crowded together or connate; ovary half inferior; style dilated at the tip; stigma concave, entire or slightly 2-lobed. —Species 20-25, Brazil. Allied to Gesnera, Isoloma, and Achimenes, and of similar cultural requirements. The genus includes the cult. gloxinia, which is properly Sinningia speciosa, Benth. & Hook., but which is treated in this book under Gloxinia. Other than this species, the sinningias are little known horticulturally, although some of the species have much merit. {{SCH}} }} ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Species== *''[[Sinningia aggregata]]'' *''[[Sinningia brasiliensis]]'' *''[[Sinningia canescens]]'' *''[[Sinningia cardinalis]]'' *''[[Sinningia cooperi]]'' *''[[Sinningia iarae]]'' *''[[Sinningia incarnata]]'' *''[[Sinningia leucotricha]]'' *''[[Sinningia lineata]]'' *''[[Sinningia macropoda]]'' *''[[Sinningia × pumila]]'' *''[[Sinningia speciosa]]'' *''[[Sinningia tubiflora]]'' The Brazilian genera ''[[Paliavana]]'' and ''[[Vanhouttea]]'', consisting of shrubby plants without tubers, are closely related to ''Sinningia'' and recent morphological and molecular analyses (Boggan 1991, Perret et al. 2003) suggest that these genera are, in fact, nontuberous ''Sinningia'' species. All three genera were included in tribe Gloxinieae in the classification system of [[Hans Wiehler]] but are now recognized in their own tribe, Sinningieae. Numerous genera, including ''Corytholoma'', ''Rechsteineria'' and ''Lietzia'', have been synonymized under ''Sinningia''. ==Gallery== <gallery perrow=5> Image:Sinningia speciosa (cultivar) 01.jpg| Sinningia speciosa (cultivar) Image:Sinningia canescens.jpg| Sinningia leucotricha Image:Upload.png| photo 3 </gallery> ==References== <references/> <!--- xxxxx *Flora: The Gardener's Bible, by Sean Hogan.
