Gary,
I googled C. mossiae (didn't know it was the national flower of Venezuela).
The photo I found at:
http://www.orchidworks.com/orchids/cattleya/july070.htm illustrates an
orchid very similar if not identical to mine. Could it be I have the
species? The plant came from the same Chinese flower shop I found the cym in
and the pot it came in is the kind associated with outdoor nursery stock,
not orchids.
Took your advice on the cym and divided it. I'm glad I did because the roots
were not that vigorous and I found some rot at the core. I used 2 - 8" bell
clay pots. See the result at: www.riva.ca/cym.jpg
