}}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. Circa 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 ( see below ).
  • Combera Sandw. 2 species native to Patagonia : Combera paradoxa Sandw. from Argentina ( provinces of Neuquén and Rio Negro and adjoining parts of Chile ) and Combera minima Sandw., a very rare species endemic to the Chilean province of Valdivia. Dwarf herbaceous perennials - alpine xerophytes growing in scree. C. paradoxa is a most 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. pichi, 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 1m ), 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 plant name may be Mapuche language homonym with 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 : only species Plowmania nyctaginoides (Standl.) Hunz. & Subils., ( common name in English Chiapas red trumpet ) endemic to the Montane rainforests of southern Mexico and Guatemala. A small, scandent (= scrambling ) 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 ( syn. B. nyctaginoides Standl. ).[3][8] The genus Plowmania is named in honour of ethnobotanist and expert on the genus Brunfelsia the late Dr. Timothy Plowman (1944-1989).[9]

The Patagonian genera Benthamiella, Combera and Pantacantha merit referral from subfamily Petunioideae to subfamily Goetzeoideae of the Solanaceae.

Ornamental use

The genera Brunfelsia, Plowmania ( see above ), Fabiana, Nierembergia and Petunia furnish garden plants bearing attractive flowers. Brunfelsia and Plowmania are genera of tropical shrubs requiring glasshouse protection in temperate climate areas; Fabiana species are hardy shrubs; Nierembergia species are dwarf, hardy herbaceous perennials or sub-shrubs, and Petunia × atkinsiana has yielded a huge variety of flower colours, forms and patterns that have made it deservedly a favourite summer bedding plant. Petunia is by far the best-known genus of the subfamily in popular temperate zone horticulture.[10]

Medicinal use

Fabiana imbricata ( Chilean vernacular name pichi ) is used as a diuretic and digestive in the folk medicine of Chile. Studies have revealed it to contain sesquiterpenes possessing gastroprotective properties.[11]

A number of Brunfelsia species have played very important rôles in the folk medicine of peoples indigenous to South America, having been used to treat conditions as diverse as syphilis, rheumatism, yellow fever and snakebite. The roots are the most effective parts of the plants and possess diuretic and diaphoretic ( = sweat-inducing ) properties.

Medications prepared from Brunfelsia species have the curious effect of producing the sensation of chills, this being the rationale for their folk use in the treatment of fevers.[12]

Hallucinogenic use

Species belonging to the genera Brunfelsia, and Petunia have been employed as entheogens in South America,[12] while the species Nierembergia hippomanica has been reported to have toxic and hallucinogen-like ( whence the specific name hippomanica ) effects upon horses and to have similarities in its chemistry to that of the genus Brunfelsia.[13][14][15]

Note : the unusual epithet hippomanica is a compound of the Greek elements ἵππος (= (h)ippos ) horse and μανία (= mania ) insanity / frenzy - hence "sending horses insane". Botanist John Miers references in the species name a plant hippomanes of uncertain identity mentioned in the idyll of Theocritus and the works of Theophrastus - so called either because horses were madly fond of it, or because it sent them mad if they fed upon it. The Greek name hippomanes was also referenced in the creation of the genus name Hippomane for an extremely toxic genus in the Euphorbiaceae.[16]

Petunia violacea Lindl. has been reported to be used as a hallucinogen in Ecuador, where it has the vernacular name shanín. The drug is said to cause sensations of levitation and flight - a type of hallucination often associated with the use of the more toxic hallucinogenic plants of the deliriant type e.g. the tropane-containing Atropa and Hyoscyamus - active constituents of the witches' flying ointments.[17]
