Cattleya dolosa alba
 

Cattleya dolosa alba

I don't think I've seen one that open and wide! Do you know the parents? It's beautiful!

No, no idea about the background.
I have this one already about 20 years.
Its an old one

Oh, it’s a stunner! Any chance you’ll ever self it?

I dont think so.
I sent pollen around the world now and then when somebody ask me, i dont make seed myself.

its a primary cross,
Cattleya loddigesii × Cattleya walkeriana
I have 2 that are almost blooming size both sunbulb baggie plants in 4 inch pots, $16.98

nice one. dolosa is considered loddigesii x walkeriana by the RHS but I think some suspect a hybrid swarm in nature. wild-collected dolosa are probably some combination of these two species, but I wouldn't bank on a straight up 50/50 genetic makeup

I would refine that to say wild hybrids between the two species are known (called x dolosa), but I haven't ever heard it called a hybrid swarm, which denotes many species involved (think Encyclia). The artificial hybrid is called Cattleya Heathii, so the correct name on this one would be determined by who made it: nature or a person with a toothpick.

technically Heathii is harrisoniana x walk. Dolosa is the primary hybrid loddigesii x walk.

Heathii appears to be harrisoniana x walkeriana in RHS, which is news to me. I've never heard of this since in practice, it's always the artificial hybrid of loddigesii x walkeriana.

Here's a link to the OrchidRoots page...which links to the RHS page! Cattleya Heathii 1

I have to admit, I don't know why this discrepancy exists. Still, x dolosa is only for the natural hybrid, not the artificial one.
