I hope you find them, I have never been able to locate them. I remember my SYstematics Prof. saying they hadn't been reported in 20 years. That was in the early 80's. Sounds like thing might have changed and that would be great!
Dustin thanks for the list. You can add U. cornuta to that list, I found it in Oneonta, NY. I don't think D. anglica has ever been in NY, but I could be wrong I suppose. Ihave never found U. inflata or U. purpurea, but if anyone ever hears of a site where they are, please let me know! It must be well South of us Dustin. I had both species thriving outside in a minibog along with U. gibba. None of them made it through the winter, for what that's worth.
Tomorrow I am going hunting for U. intermedia. You can see that at Fair Haven, State Park if you have a row boat or rent a canoe. It should likewise be in flower.
Another cheery note is I found D. intermedia in my local bog, which I have not found in 15 years. YAY! I also learned that the property did not change ownership as I had feared. The logging company that owns it posted it, but the caretaker is the guy that always comes and checks me out when I go to the bog. I have explained my interest and he is all fine with it. I would be utterly devestated should something happen to my bog. As it is, ATV's have altered the drainage characteristics, and there are discernable differences in the phytosociology there. As bogs go, it is an older one, not yet compromised by the presence of hardwood trees, but in goeological terms, it won't be long.
