Rhodophiala

Rhodophiala is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae[2]). It consists of about 30 South American species distributed in southern Brazil, Argentina, and, specially, in Chile. Most of the species are known colloquially as añañuca.

Rhodophiala species resemble small-flowered Hippeastrum or multiflowered Habranthus species. Their narrow parallel-sided leaves are unlike that of Hippeastrum, more closely resembling that of Habranthus or Zephyranthes.[3]

At one stage, Rhodophiala was considered a subgenus of the closely related Hippeastrum.[4]

Although as of February 2016 not yet accepted by the World Checklist of Selected Plant Families a number of species of Rhodophiala have been rehabilitated as Rhodolirium.[5][6]
