Caliphruria

Caliphruria is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae[2]). It consists of four species distributed in tropical regions of South America, three of them are endemic to Colombia. This genus is closely related with the genera Eucharis and Urceolina, all of them known as "Amazon Lilies". The species of Caliphruria are infrequent in nature.

Description

Members of Caliphruria have petiolate leaves with a distinctive cuticular striation and white flowers with the shape of a funnel. The six tepals are fused at their bases forming a straight perianth tube and the six stamens of the androecium are more or less fused developing an "staminal cup". Seeds are turgid, with a lustrous, usually black, testa.[3]

Species

The list of Caliphruria species, with their complete scientific name and authority, is given below.[4]

Distribution and habitat

The genus is restricted in distribution to the Cordillera Occidental and Cordillera Central of Colombia. The species of Caliphruria are rain forest geophytes adapted to the low light conditions of the forest understory.

Conservation status

Many of the species of the genus are endangered. Caliphruria korsakoffii, from Peru, is very infrequent; Caliphruria hartwegiana and Caliphruria subedentata are threatened by extinction; and Caliphruria tenera is considered to be extinct.[9]

Uses

C. korsakoffii is cultivated as an ornamental plant.
