I've been trying to figure this one out for a while now. What I've got so far is “Potamogeton hybridum varietas natantum”, “in stagni Carolinae”, “schedulo in herb. Michaux, musei regdi”, "A v. Chamisso" (Adelbert von Chamisso). I can't figure out the word I've got as "regdi"... do you think I transcribed it correctly? I can't figure out what Latin word it should be.

Thanks so much for your help!
