Dear Bryon,

Your Sobralia is without a doubt S. sessilis. This is a South American species that is more boldly colored than the various things lumped under the Central American S. decora. Most (?) S. decora produce branched growths while S. sessilis tends to produce unbranched stems about 3 feet long (depending on growing conditions). Both have short black hairs on the leaf sheaths.

At the moment, though, I am trying to finalize a manuscript on Stenorrhynchos - with at least two new species hiding within the entity we call S. speciosum. A messy business that seems to be resolving itself - finally.

All for now, Eric

Here are some color photos of the Sobralia species I sent to you for an ID about 1 year ago. I do not know the country of origin. I don't know if these will help you any more. Did you get the box of things I needed to have ID'd? I was mailed 10/05/2003?
