Greetings:
Let's try again (first thread was "lost" in cyberspace when previewing the post).
The attached jpg is of a marking that appeared on a leaf of a cattleya that I've had for several years. It's an "orphan", but I think that it's probably a hybrid of C. bowingiana, based on the bulbous base of the pseudobulbs.
Any thoughts?
Regards,
Dan
