Ron Heberle's Cyrtostylis

(Mosquito Orchids).

There are just three named species in the south west of WA.

These have been proved to be present as far north as Kalbarri and as far east as Israelite Bay. However the major distribution is in the high rainfall areas of the extreme southwest where these colony forming species can be abundant.

The three species are C. heugelii, C. robusta and C. tennuissima. There is also an unnamed species from the Tone River featured here.
