Thank you, Ray. I'm also looking for the more detailed RULES re: the use of Latin, priority in naming and other rules that taxonomists battle over with each other. I have read some real doozies through the years on other Forums!

With additional effort, I came across the following resources:
Robert Bedard Horticulture : Orchid Nomenclature
In Bedard's article cited above, he references:
"The Handbook on Orchid Nomenclature and Registration" is perhaps the definitive source for information on this subject. You should be able to obtain it from the American Orchid Society

First, lancifolium is a straightforward synonym of cochleatum.

Second, for most of its existence trulla was mistakenly called lancifolium.

Third, the hybrid was made as cochleatum x lancifolium but the lancifolium was actually trulla. That is to say the actual plant used was trulla.

Fourth, both cochleatum and trulla are put in either Anacheilium or Prosthechea by authors but they are absolutely of the same genus and neither one is an Encyclia.

So it is either Anacheilium Green Hornet or Prosthechea Green Hornet but it is a hybrid and not just a crossing of two cochleatums.
