Clo. Black Jade

[Roberta]

I looked this one up, and there are some cultivars with dark red on the lip - might have been the first one to bloom and so inspired the name. It's Cl. russelliana (very green) x Ctsm. expansum (some cultivars are green with yellow throat, but some have a lot of red... so the color of the hybrid would depend on which Ctsm. expansum was used, any cross of different individuals of the two species would have the same name)
