Ok, I have collected a number of articles on slipper phylogenetics and wonder if I am missing any (from 1978 on, before then I'm ignoring for the moment). If anyone sees any gaps, please let me know!

Those are some from my advisor Dr. Martha A. Case. Hopefully some will be of interest to you.

Thanks, I have them all! very interesting articles on cyps.

Really? There are actually a few of those I couldn't track down. I'll PM you a few I've been looking for in a few minutes.

Stephen,
Most of your citations are relatively recent. Are you interested in any of the older cytogenetic literature on slippers.
Dean Stock

Dean,

At the moment I'm sticking to the more recent stuff. I have a few of the older cytological articles, but it's a lot of literature.

Cox, A. V had constructed a phylogeny tree of Cypripedium, but only abstract was available in Am. J. Bot. 81 (6 SUPPL.) : 150 1994. I really want to know the relationship of the 47 species of Cypripedium.
