Rufodorsia is a genus of epiphytic flowering plants in the family Gesneriaceae. The genus name refers to the reddish back of the upper lobes of the flower. It is native to montane cloud forest in Central America.

Description

Rufodorsia species are epiphytic perennial plants, with little-branched upright or hanging stems. The leaves are opposite and of similar sizes with a leathery blade. The inflorescence is an axillary cyme with one to ten flowers. The flowers are short, with fused petals forming a bell shape. The free ends of the petals (lobes) differ: the lowest is larger, making the flower appear two-lipped. The flower is whitish, except for the back of the upper two lobes which is reddish. There are four stamens, included within the flower. The fruit is an almost translucent white berry with fleshy pulp. [2]

Taxonomy

The genus was erected by Hans Joachim Wiehler in 1975 for four species, three new and one originally described in the genus Besleria . The genus name is derived from Latin rufus 'red' and dorsum 'back', referring to the reddish back of the flowers. [2]

Genus Oerstedina was erected in 1977, initially with two new species. The genus name honoured Anders Sandøe Ørsted, a Danish botanist who explored and collected in the neotropics between 1845 and 1848. Wiehler noted that Oerstedina was close to the genus Rufodorsia. [3] }}

Molecular phylogenetic studies showed a sister relationship between Rufodorsia and Oerstedina, [4] [5] and in 2010, Ricardo Kriebel transferred one species from Oerstedina to Rufodorsia as Rufodorsia cerricola. [6] Plants of the World Online treats Oerstedina as a synonym, and its former species have been placed in Rufodorsia. [1] [7] [8]

Species

Four species were originally placed in the genus, [2] and are recognized in a 2020 list of New World members of the family Gesneriaceae, [9] as well as by Plants of the World Online as of April 2021: [1]

One additional species transferred from Oerstedina is accepted by Plants of the World Online as of April 2021: [1]

Distribution and habitat

The four original species of Rufodorsia are native to Central America, from Nicaragua through Costa Rica to Panama. They are found in montane cloud forest and sub-cloud forest at elevations of 450–1,500 m (1,500–4,900 ft), R. major at the lowest levels and R. congestiflora at the highest. [2]

Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World and the New World, with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.

<i>Columnea</i> Genus of epiphytes

Columnea is a genus of around 200 species of epiphytic herbs and shrubs in the family Gesneriaceae, native to the tropics of the Americas and the Caribbean. The tubular or oddly shaped flowers are usually large and brightly colored – usually red, yellow, or orange – sometimes resembling a fish in shape. A common name is flying goldfish plants due to the unusual flower shape.

<i>Kohleria</i> Genus of flowering plants

Kohleria is a New World genus of the flowering plant family Gesneriaceae. The plants are generally tropical herbs or subshrubs with velvety stems and foliage and brightly colored flowers with spots or markings in contrasting colors. They are rhizomatous and commonly include a period of dormancy in their growth cycle. The genus was revised in 1992 and was then recognized as having 19 species distributed in Central America and South America. phylogenetic in 2005 indicated that the epiphytic genus Capanea is derived from within Kohleria, and the two species of Capanea were subsequently transferred to Kohleria. The genus Pearcea is closely related.

<i>Seemannia</i> Genus of flowering plants

Seemannia is a New World genus in the flowering plant family Gesneriaceae. There are four species in the genus, primarily found in the Andean regions of South America. The name honors the German botanist Berthold Carl Seemann.

<i>Pearcea</i> Genus of flowering plants

Pearcea is a genus of tropical herbaceous plants in the family Gesneriaceae native to western South America. It is classified in tribe Gloxinieae and is closely related to the genus Kohleria, in which some of its species were previously included. The genus Parakohleria has recently been synonymized under Pearcea, a conclusion later supported by molecular analyses that showed that Pearcea hypocyrtiflora was nested within the former Parakohlerias.

<i>Gasteranthus</i> Genus of flowering plants

Gasteranthus is a genus of 35 species of herbs and soft-stemmed subshrubs in the flowering plant family Gesneriaceae. The species occur in Central America and South America, from southernmost Mexico to Bolivia. Numerous species are threatened with extinction, mainly due to deforestation. This is due to two reasons: For one thing, Gasteranthus species are native to countries in which destruction of primary forest runs rampant; also, these plants do not distribute well and therefore endemism is very frequent, for example on isolated mountain ranges.

<i>Nematanthus</i> Genus of epiphytes

Nematanthus is a genus of flowering plants in the family Gesneriaceae. All of its species are endemic to Brazil. Compared to other gesneriads, Nematanthus has leaves that are small, succulent, and hard-surfaced. The plant has a trailing, branching, and spreading habit; it is generally an epiphyte in nature and a hanging-basket plant in cultivation. The flower has fused petals. In some species, the flower has a "pouch" at the bottom. The fancied resemblance of such flowers to a goldfish gives these plants the common name goldfish plant or guppy plant.

<i>Alloplectus</i> Genus of flowering plants

Alloplectus is a genus of Neotropical plants in the family Gesneriaceae. A 2005 revision of the genus included five species, with the majority of species in the genus as traditionally circumscribed being transferred to Crantzia, Glossoloma, and Drymonia. Plants of the World Online currently accepts seven species.

<i>Nautilocalyx</i> Genus of flowering plants

Nautilocalyx is a genus of plants in the family Gesneriaceae. Its native range stretches from Costa Rica to southern Tropical America and to Trinidad. It is also found in Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Panamá, Peru, Suriname, Trinidad-Tobago and Venezuela.

<i>Codonanthe</i> Genus of epiphytes grown as houseplants

Codonanthe is a genus of mainly epiphytic plants in the family Gesneriaceae, endemic to the Atlantic Forest of Brazil. The botanical name comes from the Ancient Greek for 'bellflower'. They have white or pale pink flowers and somewhat fleshy leaves. In 2013, the genus was reduced in size when more than half of the species were transferred to Codonanthopsis. They can be grown as houseplants, particularly in hanging baskets. Artificial crosses with Nematanthus hybrids have produced the hybrid genus × Codonatanthus.

<i>Corytoplectus</i> Genus of flowering plants

Corytoplectus is a genus in the plant family Gesneriaceae. Plants from Corytoplectus are found in Bolivia, Brazil North, Colombia, Ecuador, Guyana, southwestern Mexico, Peru, Venezuela, in the cloud-forests of the high cordillera. The genus contains c. 12 species. The genus differs from the closely related Alloplectus in having an erect umbellate inflorescence and berries. The type species is C. capitatus.

<i>Trichodrymonia</i> Genus of flowering plants

<i>Codonanthopsis</i> Genus of flowering plants

Codonanthopsis is a genus of flowering plants in the family Gesneriaceae. Its native range is from southern Mexico through tropical America to Bolivia and most of Brazil. Codonanthopsis species are generally trailing epiphytes with pale flowers. Most have a mutualistic relationship with tree-living ants: the plants provide the ants with food, including nectar, and give their nests structure and support, while the ants disperse the plants' seeds. The genus was considerably expanded in 2013 when species were transferred from Codonanthe. Some Codonanthopsis species are cultivated as houseplants, when they may be grown in hanging baskets.
