Iridaceae is a family of plants in order Asparagales, taking its name from the irises. It has a nearly global distribution, with 69 accepted genera with a total of c. 2500 species. It includes a number of economically important cultivated plants, such as species of Freesia, Gladiolus, and Crocus, as well as the crop saffron.
Begoniaceae is a family of flowering plants with two genera and about 2040 species occurring in the subtropics and tropics of both the New World and Old World. All but one of the species are in the genus Begonia. There have been many recent discoveries of species in the genus Begonia, such as Begonia truncatifolia which is endemic to San Vincente, Palawan. B. truncatifolia is smaller in size than other species of the genus Begonia and this new species is proposed Critically Endangered by standards set by the IUCN. The only other genus in the family, Hillebrandia, is endemic to the Hawaiian Islands and has a single species. Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family. The genus Symbegonia was reduced to a section of Begonia in 2003, as molecular phylogenies had shown it to be derived from within that genus. Members of the genus Begonia are well-known and popular houseplants.
Beaucarnea is a genus of flowering plants native to Mexico and Central America. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae. Beaucarnea is sometimes treated as a synonym of the genus Nolina, with the species being then transferred to that genus. However, recent research shows that Beaucarnea should be treated as an independent genus.
Turnera is a genus of flowering plants in the passionflower family, Passifloraceae. It contains more than 100 species native to tropical and subtropical America. The name honours English naturalist William Turner (1508–1568). It was previously placed in the family Turneraceae.
Afroqueta is a genus of flowering plants belonging to Turneroideae (Passifloraceae). It is a monotypic group, consisting of Afroqueta capensis(Harv.) Thulin & Razafim.
Oxossia is a genus of flowering plants in the subfamily Turneroideae (Passifloraceae) consisting of 15 species. This genus was recently defined in 2019 after a phylogenetic analysis of Turnera justified the creation of the genus. The genus is characterized by its stipules, small flowers, congested inflorescences, "hairy" stamen and style, and the attachment of stamen to the floral tube. All members of the genus are heterostylous with the exception of O. dasystyla. The genus can be divided into two morphological groups: those with white petals and those with yellow pink or red petals.
Oxossia albicans is a subshrub in the genus Oxossia. It is native to the wet tropics of eastern Brazil, specifically the Atlantic forest. It is 40 - 80 cm tall and has yellow heterostylous flowers.
Oxossia annularis is a shrub of Oxossia Turneroideae (Passifloraceae) native to eastern Brazil. It is found in Caatinga, Cerrado, and Atlantic Forest. O. annularis has 2–10 mm long petioles, rigid elliptical, ovate, or obovate leaves with serrated margins and heterostylous flowers.
Oxossia calyptrocarpa, a member of Turneroideae (Passifloraceae), is a shrub native to the wet tropics of eastern Brazil. It is found in the Caatinga, Cerrado, and Atlantic forest. It is 0.2-2.5 meter tall with highly plasticitic leaves and white to lilac flowers. It is a heterostylous species.
Oxossia capitata is a shrub native to the wet tropics of southern Brazil. It was previously classified as Turnera, however, recent phylogenetic analyses suggested the species should be placed in Oxossia.O. capitata has heterostylous white pointed flowers.
Oxossia dasystyla is a shrub native to southeast Brazil. It is native to the jungles and surrounding fields of Minas Gerais; specifically the Caatinga and Atlantic Forest.
Oxossia hatschbachii is a species of shrub in the genus Oxossia (Passifloraceae). It is native to the Atlantic Rainforest near Espírito Santo, Brazil. O. hatchbachii has heterostylous racemose flowers, ranging in color from white to red.
Oxossia hebepetala is shrub in the genus Oxossia (Passifloraceae). It is native to the Caatinga of Bahria and Piauí, Brazil.
Oxossia maracasana is a shrub in the genus Oxossia (Passifloraceae). It is native the Caatinga regions and Atlantic forest near Bahia, Brazil. It has white heterostylous flowers.
Oxossia marmorata is a shrub in the genus Oxossia (Passifloraceae). It is native to the Atlantic Rainforest of Brazil. It can be distinguished from other members of the genus by its yellow flowers. Similar to other members of Oxossia, O. marmorata has distylous flowers.
Oxossia princeps is a subshrub in the genus Oxossia (Passifloraceae). It is native to the savanna of Minas Gerais, Brazil. It is considered "rare", but its conservation classification is currently unknown.
Oxossia rubrobracteata is a shrub in the genus Oxossia (Passifloraceae). It is native to the Atlantic Rainforest of Brazil.
Oxossia schomburgkiana is a shrub in the genus Oxossia (Passifloraceae). It is native to the Amazon Rainforest of Brazil.
Oxossia spicata is a shrub in the genus Oxossia (Passifloraceae). It is native to the Atlantic Rainforest of Espírito Santo, Brazil. The species is known from three different populations, however, additional field work is needed to determine the conservation status of O. spicata.
Oxossia waltherioides is a subshrub in the genus Oxossia (Passifloraceae). It is native to the Amazon Rainforest of Roraima, Brazil.
