I've been trying to compile pictures and information on all the Cypripedium species. However, I haven't been able to track anything down on the following 4. I figure they are either very newly described or are synonyms. Any idea, anyone? Thanks.

Cypripedium morinanthum
Cypripedium neoparviflorum
Cypripedium roseum
Cypripedium sinapoides

Hmm, I have no references to any of those. Many Paphs were once in Cypripedium but the names you mention do not ring bells for me there either. Where did you find the names?

Dear Zach,
I found the following data about these species
Cypripedium morinanthum Y.N.Lee
described in Bull. Korea Pl. Res. 2: 31 (2002).
Distribution: Manchuria?
Type Information
Collector(s): Y.Lee; Y.Kim
Locality: Mt. Baektu (Mt. Jangbaek)
Collection Date: 2002-6-1
Type Location: holotype Korea Plant Research Institute

Cypripedium neoparviflorum Y.N.Lee
described in Bull. Korea Pl. Res. 2: 31 (2002).
Distribution: Manchuria?
Type Information
Collector(s): Y.Lee; Y.Kim
Locality: Mt. Baektu (Mt. Jangbaek)
Collection Date: 2002-6-9
Type Location: holotype Korea Plant Research Institute

Cypripedium roseum Y.N.Lee
Bull. Korea Pl. Res. 2: 32 (2002).
Distribution: Manchuria?
Type Information
Collector(s):Y.Lee; Y.Kim
Locality: Mt. Baektu (Mt. Jangbaek)
Collection Date: 2002-6-1
Type Location: holotype Korea Plant Research Institute

Cypripedium sinapoides Y.N.Lee
Bull. Korea Pl. Res. 2: 30 (2002).
Distribution: Manchuria?
Type Information

I am looking also for the original description and have no possibility to get the korean journal. Perhaps somebody can help with a scan.

Best greetings

Olaf

Dear Zach,
there is also a 5th species.
Cypripedium agnicapitatum Y.N.Lee in Bull. Korea Pl. Res. 2: 28 (2002)-Manchuria?

Have you any information about this?

Best greetings

Olaf

WOW that's a lot of information.... Thank you! As for Cyp. agnicapitatum, this is the only image/information I could find:

Whether or not the image acually displays an agnicapitatum, I have no idea.

Zach,

All of these plants currently fall outside the boundaries of accepted botanical knowledge, at least in the west. Perhaps some of the folks from China on this forum can be more of service in telling what these are or even have experience growing them.

My own take on it is that they are just various hybrids belonging to the highly variable group of plants that fall under the name C. x ventricosum. It is well known that Manchuria and adjacent parts of Russia (and perhaps North Korea) have a hybrid swarm of the two species C. calceolus and C. macranthos (even C. shaxiense may be involved in some). The complexity of these cannot be known, but no doubt there has been a lot of back crossing between the hybrids themselves as well as to the original two species. To me it sounds like a couple scientists got into a naming spree one day (notice they are all from the exact same area).

Time will tell what they really are, but for now I wouldn't expect too much hard information or published pictures of them. BTW the following plants are also considered by most botanists to be synonymous with x ventricosum: C. x barbeyi, C. x freynii, C. x krylowii, C. x manschuricum, and C. x rubronerve.

TomTom, I'd have to agree on that hybrid thing. Exact same location and everything. Anyway, thanks for that list of x ventorsicum synonyms, that'll help.

Has somebody the article, where these plants were described and could mail it.

Best greetings and many thanks for the information

Olaf

There is a description in Der Orchidee about the trip Holger Perner took to Sibiria. It is a two part article and I only have the first part. This part has only little of the good pictures of that trip.
If You were talking about the Lee article I know knothing.


I think it is possible through the Orchidee webpage to find what written in Each number.
Good luck finding the article.
Kind regards
Joakim
