I'm not saying it was. The tag was gone so I went through pictures and found one that I thought looked like it. So either someone did, or I am associating an old photo with the wrong plant. I don't see any record of me ever having a ramispina x ventricosa hybrid though. :-\ But I do see I received a black knight from @uphwiz back in 2011, I wonder if that's it! I have other black knights now (more recent much smaller) so seeing that name on my lists didn't really stand out as a possibility.I'm disappointed by whoever is distributing that plant labeled as sib x copelandii. It's one of the ramispina x ventricosa variations.
Actual sibuyanensis x copelandii look about like you'd expect a sib x alata cross to look like, but darker. Fat, heavily patterned, broad peristome, etc.
Well, there is a photo of one of them here from 2008, so before that.Those albos are seriously nice. How long from seed are they?
