Dear Wikiwand AI, let's keep it short by simply answering these key questions:

Can you list the top facts and stats about Petunioideae?

Summarize this article for a 10 years old


Petunioideae is a subfamily of the flowering plant family Solanaceae, the nightshades. It contains thirteen genera, as follows:[1][2][3][4]

  • Benthamiella Speg. 12 species native to Patagonia: caespitose ("cushion-forming") dwarf shrubs. The species B. pycnophylloides Speg. bears the Spanish common name leña de piedra ("the kindling that grows on rock") in its native Argentina.[5]
  • Bouchetia Dunal 3 neotropical species.
  • Brunfelsia L. Approximately 45 neotropical species. Shrubs with lavender or white flowers with slender tubes and narrow mouths in the centre of broad salver-form corolla lobes. Several species with medicinal and hallucinogenic properties.
  • Combera Sandw. 2 species native to Patagonia: C. paradoxa Sandw. from Argentina (provinces of Neuquén and Rio Negro and adjoining parts of Chile) and C. minima Sandw., a very rare species endemic to the Chilean province of Valdivia. Dwarf herbaceous perennials – alpine xerophytes. C. paradoxa is an attractive plant meriting cultivation as an ornamental, bearing rosettes of dark green leaves contrasting with pale, fragrant flowers borne in profusion. Corollas white, tinged violet, contrasting with showy, bright yellow stamens and narrow-lobed, hairy, purple calyces.[3][5][6]
  • Fabiana Ruiz & Pav. known as pichi or false heath, 15 species from the Andes.
  • Hunzikeria D'Arcy 3 species from the southwestern United States and Mexico.
  • Leptoglossis Benth. 7 species from western South America.
  • Nierembergia Ruiz & Pav. cup flowers, 21 species from South America.
  • Pantacantha Speg. monotypic genus from western Argentina and Patagonia, the single species being Pantacantha ameghinoi Speg.,[7] a low (usually less than 1 m), spiny-leaved shrub bearing small, pale yellow, urceolate ("urn-shaped") flowers attractively striated with purple, native to the south of Mendoza Province in western Argentina and also to the Argentinian provinces of Neuquén, Río Negro and Chubut. The small, bell-like flowers and linear leaves give the shrub an Erica-like appearance. Common names in its native Argentina: quila or quilla (Spanish quilla translates as "keel" but the plant name may be a Mapuche language homonym with an entirely different meaning).[3][5]
  • Calibrachoa Cerv. ex La Llave & Lex 32 neotropical species segregated from Petunia.
  • Petunia (Juss.) Wijsman 18 species from South America.
  • Plowmania Hunz. & Subils monotypic genus with only 1 species, Plowmania nyctaginoides (Standl.) Hunz. & Subils., (common name Chiapas red trumpet) endemic to the Montane rainforests of southern Mexico and Guatemala. A small, scandent shrub with large and attractive flame-coloured flowers (somewhat reminiscent of those of the better-known ornamental Ipomoea coccinea), cultivated as an ornamental in the United States. First classified as a Brunfelsia (synonym B. nyctaginoides Standl).[3][8] The genus Plowmania is named in honour of ethnobotanist and expert on the genus Brunfelsia, Timothy Plowman (1944–1989).[9]
