Collierara is a multigeneric hybrid in the Cattleya Alliance.1 Three of the genera involved, Brassavola, Cattleya, and Laelia, are pretty ordinary -- everything has them in it -- but then there's a new one: Caularthron, which sounds less like a flower and more like someone from Greek mythology. Good old star-eyed Caularthron, people would say. Shame about that thing with Poseidon.
Judging from the pictures that come up when one searches Caularthron, I'm guessing that's where the pointier, more angular aspect of Collierara (compared to, say, Brassolaeliocattleya) comes from.
Anyway. I'm extremely fond of this one, more for the shape than the color, though the color is very nice too. I think I might even want one.
1 Or should it be, "Cattleya alliance?" When I capitalize "alliance" I feel like I'm writing a report for history class about World War II or something.
