Species in this genus can be found growing 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 leaves, terminating in a small white non-resupinate flower. This lip is fringed and hood-shaped. The flower gives off a pungent smell that attracts flies. This genus has often been included in the orchid genus '' Altensteinia''. The first scientific description of a species of this genus was made in 1815 by Karl Sigismund Kunth, naming it first ''Ophrys paleacea'' Kunth (1806)., and later ''Altensteinia paleacea''. In 1854 Heinrich Gustav Reichenbach separated ''Aa'' from ''Altensteinia'', to include two species ''Aa argyrolepis'' and ''Aa paleacea''. The genus name apparently was rendered by the author to always appear first in alphabetical listings. Another - disputed - explanation, is that H ...

He became a Doctor in Botany with his work on the pollen of orchids (see ‘Selected Works’). Soon after his graduation, Reichenbach was appointed to the post of extraordinary professor of botany at the Leipzig in 1855. He then became director of the botanical gardens at the Hamburg University (1863-1889). At that time, thousands of newly discovered orchids were being sent back to Europe. He was responsible for identifying, describing, classifying. Reichenbach named and recorded many of these new discoveries. He probably was not the easiest of personalities, and used to boast about h ...
