Gga quinquinervis alba x2
?? I thought there shouldn't be any red/brown (anthocyanins) color in an
alba... K Barrett "v_coerulea" wrote in message ... These are 3" flowers on 1 1/2' long stems and quite fragrant. Gary |

Right you are, Kathy. I purchased this from Carter & Holmes as Gga
quinquinervis alba x self. As far as I know, there's no way an alba x self can revert to the colored form. I wrote to C&H and haven't heard back yet. I'll let you know if there's a reasonable answer. Unless anyone else knows anything about alba Gongoras not being real albas or having complex genes as in white Catts? Gary "K Barrett" wrote in message . .. ??

Gga quinquinervis alba x2
All I know is many times a vendor will get what's purported to be an alba.
Their plant has white flowers but the only way to be sure if its a true alba is to self it and see if all the progeny are white too. Of course many times ~3/4 of them are colored and ~1/4 are true albas. Maybe less, actually, because in orchids color is controlled by 2 genes, they both have to be switched 'off' in order for true albinism to occur. The color reversion comes from a white flower having just a hint of color elsewhere in the flower - like in the throat, a tinge on the back of the sepal or someplace else. When crossed to itself the genes all pair up and yeild colored flowers. Only the lucky few are all switched off and therefore albas. Koopowitz talks about this in his book on paphs, about how they (Paphfanatics) used to do alot of this sort of cross testing in order to find/create the one true alba. I guess they had bench space...

Gga quinquinervis alba x2
I checked everywhere I could think of and the pictures of quinquenervis had
no where near as much white as mine does. So maybe it's only half alba. Anyway, I'll let you know what Gene Crocker or Mac Holmes have to say about it. They're usually very good about answering questions even though Gene has a schedule that would make your head spin. And he still manages to get all the crosses done that he does each year.
