Cypère doré[e] which in Latin would be Cyperus aureus doesn't seem to exist since I could not find it anywhere on the Net. On the other hand, Wikipedia and others give souchet tubéreux, souchet sucré, souchet sultan, amande de terre, gland de terre, noix tigrée ou pois sucré as common French names for Cyperus Esculentus.
ReplyDeleteHmm, you are right. Tela Botanica doesn't list Cypère doré as a name for this species. I've written it in my notes for this species which I made on the outing when this was photographed, so someone must have referred to it in that way. Perhaps I misunderstood and thought they were referring to it by name rather than describing it. I don't know, I can't remember. I'll change the entry.
DeleteCypère doré could be a good neologism for Yellow Nutsedge !
