Abstract

Pucara leucantha is transferred to Stenomesson as Stenomesson leucanthum based on the phylogenetic position of Pucara resolved by nuclear and plastid DNA sequences. An allied species, Stenomesson chloranthum, is described from the Departments of Amazonas and Cajamarca in Peru, but at lower elevations. Both of these species release their pollen in tetrads, unique within Amaryllidaceae, and have tri-lobed stigmas, unique within Stenomesson.
