Caliphruria is a genus in the Amaryllidaceae family with 4 species native to northern Peru and low montane forests in Colombia. It is closely related to Eucharis in the Eucharideae tribe. Only two species are common in cultivation.
Caliphruria subedentata (syn. Eucharis fosteri) is native to northwestern Colombia. This plant should be grown like a Eucharis with good warm temps and filtered sunlight. Flowering is unpredictable, and probably requires a dry-ish winter dormancy. The flowers do not seem to have a scent. Photos 1-2 were taken in July 2003 by Lee Poulsen given to him by Charles Hardman. Charles says it's easier to flower than Eucharis x grandiflora. Photos 3-4 was from Hans Joschko.
