Aa erosa is a species of orchid in the genus Aa. [1] It is endemic to Peru and blooms in late winter and early spring.
As a member of the Orchidaceae family, Aa erosa (synonymous to the name Altensteinia erosa) exhibits protandy based on anatomical observations. [2] [3] In plants, protandry occurs when the male reproductive structure releases pollen before the female parts can.
The native range of this species is Peru. It is a tuberous geophyte and grows primarily in the subalpine or subarctic biome. [4]
