Oerstedina is a genus of epiphytic flowering plants in the family Gesneriaceae. The relationship of Oerstedina with the genus Rufodorsia is uncertain, as of April 2021.
Description
Species of Oerstedina are epiphytic perennial plants, with upright or hanging stems. The flowers comprising the inflorescence are tightly arranged in the leaf axils. The fused petals (corolla) are white to pinkish in colour and form a short, rather inflated tube. The fruit is a pointed berry. The genus is distinguished from Rufodorsia by the shape of the corolla and the lack of a reddish colour on its back, and the pointed shape of the berry.
Taxonomy
The genus was erected by Hans Joachim Wiehler in 1977, initially with two new species. The genus name honours 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. Molecular phylogenetic studies have shown a sister relationship to Rufodorsia, and in 2010, Ricardo Kriebel transferred one species from Oerstedina to Rufodorsia as Rufodorsia cerricola. However, the other two species of Oerstedina have not been formally transferred as of April 2021, so the two genera are not fully synonymized.
Species
Three species were recognized in a 2020 list of New World members of the family Gesneriaceae:
- Oerstedina cerricola Wiehler, syn. Rufodorsia cerricola (Wiehler) Kriebel
- Oerstedina mexicana Wiehler
- Oerstedina suffrutescens L.E.Skog
Distribution
Oerstedina is native to southwest Mexico (O. mexicana), Costa Rica and Panama.Cite error: A <ref> tag is missing the closing </ref> (see the help page).
