Well, I don't know about Orostachys, but in Trillium, "I have" several
recominations that were independantly re-combined.  The O.thyrsiflorus
citation could be an example of an old one.  In some of the older
(1800s) nomenclatural articals that *I* have, frequently the originating
author (here DC) is not indicated in a recombination.  Neither are
"in" and "ex" consistently used like they are in the more mordern
citations.  From my experience with Trillium, I'd say that it's a good
bet that O.spinosus and O.malacophyllus were just independantly recombined.
Do you have the dates for these taxa?  Have you checked the IK?

Good luck,
