Columnea ambigua, also known as tibey de cresta, is a species of epiphytic shrub endemic to the island of Puerto Rico. It adheres to rocks[2] in humid premontane and montane forests such as El Yunque.[3]

Description

Columnea ambigua has glossy, green, egg-shaped leaves and yellow flowers with green or red calyxes, supported by slender pedicels.[3] The floral morphology is assumed to be adaptive for hummingbird pollination.[4] The pollinated plant produces spherical, snow-white berries each around 7 mm in diameter.[3] Tibey de Cresta is distinguished from other Columnea species by the ratio between the length of the corolla tube and the length of the corolla lobe.[4]

Etymology

The genus was named by Carl Linnaeus for the 16th-century Italian botanist Fabio Colonna with the Latinized spelling Fabius Columnus.[5][6] The specific epithet ambigua comes from the Latin word ambiguus, meaning doubtful or uncertain.

Conservation

Tibey de Cresta was identified as a conservation concern by Miller et al. (2013), who gave it a provisional global rank of Near Threatened using the IUCN Red List criteria.[7]
