Habenaria erichmichaelii / rhodocheila / roblenii / xanthocheila

[thanos15084]

Hello,

I've been struggling with the nomenclature of the Habenaria rhodocheila complex.

Kew lists Hab. erichmichaelii, robelenii, and xanthocheila as synonyms of Hab. rhodocheila. I believe this to be wrong.

The RHS accepts all 4 taxa as distinct.

Hab. erichmichaelii is fairly easy to distinguish. The others other than color not so easy.


I guess my questions are:

Is there a dichotomous key to distinguish these 4 taxa?

In lieu of said key what are the distinguishing characters?

What are the distributional records for each taxa?

Thank you.

Tim
