Columnea
genus of plants
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 (see also the related Nematanthus) due to the unusual flower shape.
The genus was named by Carl Linnaeus after the Latinized spelling of the name of the 16th-century Italian botanist Fabio Colonna (Latin: Fabius Columnus).
The segregate genus Bucinellina is considered by many botanists a synonym of Columnea. A full list of the species now accepted in the genus, along with their synonyms, can be found at the World Checklist of Gesneriaceae.
Cultivation
Columnea species grow as epiphytic plants in the wild and require bright light, good air circulation, and a well-drained growing medium that is allowed to dry out slightly between waterings. They are very tolerant of underpotting and seem to bloom best when potbound. Most are tropical plants and are easy to grow under indoor or greenhouse conditions but some species come from high altitudes and require cooler temperatures to grow well or bloom. Many of the species are seasonal bloomers, but hybrids and cultivars can be more or less continuously blooming.
This brief starts where responsible research should: with the source description of “Columnea” as genus of plants. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of plants. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 17, 2025. The linked authority identifier is Q2573370. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
