'''''Aa''''' Rchb.f. 1854, is a [[genus]] of plants belonging to the family [[Orchidaceae]]. The genus name apparently was rendered by the author to always appear first in alphabetical listings. Another - disputed - explanation, is that [[Heinrich Gustav Reichenbach]] named this genus after [[Pieter van der Aa]]; the printer of the Dutch botanist Paul Herman's "Paradisus Batavus"<ref>[http://falco.elte.hu/eoc/ParadisusBatavus.htm Paradisus batavus]</ref>.<br />
<br />
Species in this genus can be found growing [[Soil|terrestrially]] in cold habitats near the snowline in the [[Andes]] and also in [[Costa Rica]]; they are usually found close to small streams. The elongated [[inflorescence]] grows from a basal rosette of [[Leaf|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 pungent smell that attracts [[Fly|flies]]. This genus has often been confused with the orchid genus ''[[Altensteinia]]''.<br />
