Eithealagopaivae a new critically endangered species in the previously monotypic genus Eithea Ravenna (Amaryllidaceae)

摘要

Eithea lagopaivae Campos-Rocha & Dutilh, >sp. nov. is described as the second species of the formerly monotypic genus Eithea. It is characterized by a one flowered inflorescence, completely hollow scape, white or lightly magenta-striated flower that is enclosed by spathe bracts fused for more than the lower fifth of its length. Comments on its range, habitat, phenology, as well as photographs and illustrations are provided. In addition, a distribution map and an identification key for the two species of the genus are presented and anatomical and ecological differences compared. Known by only two small populations exposed to several types of threats and without any guarantee of protection, E. lagopaivae is considered a Critically Endangered (CR) species.
