Microthelys Garay
Microthelys is a genus of about ten species once thought to be restricted to scattered
montane habitats in Mexico, Central America, and Ecuador (Pridgeon et al. 2003 ).
However, M. rubrocallosa (Robins and Greenm.) Garay (green medusa orchid) was
recently discovered in the Sacramento Mountains in New Mexico (R. A. Coleman
and Baker 2006 ). No detailed studies have been published on its pollination, but
some plants or populations are apparently autogamous. The putatively self-pollinat-
ing individuals include forms with both poorly developed and normal-appearing
rostella. The pollinia lie in direct contact with the rim of the stigma in both (Pridgeon
et al. 2003 ).
