Aa, is a genus in the Orchidaceae family, commonly known as orchids. It is classified in the subfamily Spiranthoideae, tribe Cranichideae, subtribe Cranichidinae.
The name apparently was rendered by the author to always appear first in alphabetical listings.
These species can be found in cold habitats, growing near the snowline in the Andes and also in Costa Rica. It usually appears close to small streams. The elongated inflorescence grows from a basal rosette of leaves, terminating in a small white upside down flower with the lip at the top. This lip is fringed and hood-shaped. The flower gives off a rather pungent smell, that attracts flies.
