Encyclia fragrans?

[Connie Star]

I bought this mounted orchid last year and the woman at the Feria in Atenas Costa Rica said it was an Encyclia. I think it is probably Encyclia fragrans but the petals look a little small- is this just variability?
I'm pleased that I got it to rebloom.

There are at least a couple other accepted Prosthechea species (sorry, I just can't call this Encyclia) in Costa Rica that superficially would be difficult to tell apart from Prosthechea fragrans - Psh. chacaoensis and Psh. ionophlebia.

Psh. fragrans should be a gray/green plant with a single leaf on most pseudobulbs.

Psh. chacaoensis should be a distinctly yellow/green plant with 2 leaves on most pseudobulbs.

Psh. ionophlebia should also generally have 2 leaves, but I can't find a color description.

If a mature open flower is much over 5cm it probably isn't Psh. chacoensis. A flower that small doesn't necessarily rule out the others though.

I don't know if that narrows it down for you. Pictures (plant too) and measurements when the spike is mature might help.

It has two leaves per pseudobulb, so I guess that rules out Prosthecia fragrans. The flowers are only about 2 cm. Thanks for your help.
The lady I often buy orchids from here is generally pretty good at identifying the plants but not always.

I have a set of Orchids of Costa Rica books, and going through it the flowers look most like those of Prosthecea chacoensis. The flowers are described as 1-3 cm, and these flowers are about 2 cm.
I had an Encyclia fragrans when I lived in the US (where I still spend the summers) and the flowers were different, another reason I was uncertain of the identity.
Thanks for your help, PaphMadMan!
