Greetings!
I have been looking high nd low for a plant of the primary hybrid once known as Brassoepidendrum Jim Wallace-- B. digbyana x E. mariae (now purportedly with a grex generic name of Rhynchothechea-- if one accepts lumping Encyclia mariae into Prosthechea* -- which I don't-- I hold it to be in either Encyclia (sensu latu) or Euchile, IMHO.
(* I find the name Prosthechea to be ugly, objectionably so for such a lovely plant as E. mariae-- "prosthechea" sounds like someone beginning to say "prostate"-- then clearing their throat. Decidedly unlovely! And certainly, from a taxonomic standpoint, this species and its congener E. citrina are as different from Prosthechea sensu strictu-- represented by such plants as P. vespa, P. vitellina and P. crassilabia -- as they are from Encyclia sensu strictu: if they're not Encyclias, then we should follow Carl Withner's segregation of these two Mexican species into their own genus Euchile.)
Anyhow, if somerone knows how, or from where or whom, I can obtain a plant of this hybrid, do please let me know!
Best regards, John Marmaro
