I learned today that this Encyclia hybrid is registered as Encyclia Hoosier Ruffels.
It seems dickinsoniana is a syn. for guatemalensis and so Encyclia guatemalensis x edithiana is Hoosier Ruffels, created by Leon Glicenstein ( formerly at Hoosier Orchids) and registered as such.
Well, it seems at the time of Hoosier sale seedlings were sold as guatemalensis x edithiana and dickinsoniana x edithiana.
Aren't synonyms fun?
