Yes, the S. truncata plants are the ones with pointy segments. The S. xbuckleyi are the ones that are rounded and scalloped. I have four of the xbuckleyi plants. One of them has longer and darker green segments than the others, but the other three appear to be uniform.
With the truncata hybrids, you can play with the day length and get them to bloom whenever you want. I just brought some up from the basement that I have had under lights all summer, and they have buds the size of a pea on them. I ran the lights for only about six hours, and it's pretty dark down there when the lights shut off, so I'm guessing that triggered "time to bloom" for most of them.
Another problem with Schlumbergera is that so many of them have plant patents on them. The way to get around that is to just drop the name and sell it as a NOID, or call it something else. And even now there are people on ebay selling patented Schlumbergeras, so the patent itself is no protection.
I think Easter Cactus has now been reassigned to the Hatiora family. I have a terrible time growing these; even so, I have three of them that at least aren't dying (yet) under lights. :-)
In any case, I started breeding Schlumbergeras in 2009, and have been looking for new breeding stock. I have 20 seedlings from a cross of Limelight Dancer x Beach Dancer. The majority of them will probably bloom this year. Hopefully, I will have something nice to put out there to those people who collect them.
Saw Aspen go a couple of times on ebay for over $50. YIKES!
