Hello Michael,

Your notes on dark colored Cyp. tibeticums are quite good. However, tibeticums can be "black", as black as a "black" tulip for example. In an article on the relatives of Cyp. macranthos (Die Orchidee Vol. 51, issue 6, pages 696-709, 2000) I published some photos of "black" Cyp. tibeticums. Unfortunately the reproduction was extremly lousy. The flowers are of course not as dark as coal (this is what the printed illustrations suggest) but of a dark violet-brown. When taking photos of these tibeticums with a flash on the camera, the color becomes darker and when scanned uncarefully seems to be pretty close to black. However, this depends also on the film type and the background. With daylight (overcast, afternoon or morning) the color is brighter, sometimes too bright.

So, what is the real color of a "black" Cyp. tibeticum? Well, in the field it is like blakish at first glance, i.e. the flowers are like very dark spots between the green of the surrounding vegetation. I have enclosed a photo taken in the field (an alpine meadow, very steep slope in northern Sichuan, June 2000) showing a "normal" colored Cyp. tibeticum (that means it is of an intensive purplish red) which grew as a single specimen between thousands of dark purplish brown Cyp. tibeticums, a few of them are the "black" flowers around the red one. The second photo is a close up of such a flower at this slope with my hand as background. Here the color of the flower is a bit brighter in the picture than it is in reality.

The yellowish cypripedium on the second picture is a hybrid. If it is a plant from the wild-collecting Cypripedium trade (i.e. most vendors of flowering sized species cypripediums offer mainly wild-collected material) and not an artificial hybrid from cultivation (like the ones Werner Frosch, Carson Whitlow or other well known specialists are producing and offering), then it is a Cyp. x ventricosum (macranthos x calceolus). At least it looks perfectly like a yellowish form of this natural hybrid.
