I bought this Cattleya with a missing tag and the flower almost at the end of the life. Is large about 6 inches, color yellow with the lip in purple, was in bloom in Feb.
Species can be identified, but hybrids are so variable and there are so many of them that correct identification is impossible and attaching a name to them because a person thinks it looks like a certain hybrid is irresponsible.
Fully back the statement about being irresponible to attach a name to something thats not 100% that plant.
However, I do think you could do your own investigating and come up with your own set of determinants and I will help you in that direction. It looks to me very much like a Blc. Chunyeah. Look that up, look up the hybrids that comprise it and hybrids using that as a parent and Im certain you could find somewhere to settle.
