Identificaciones de threepogonias

Stored at home too long so some of the heads fell off but it had multiple heads in the field. It was raining the day of the fieldwork so it was difficult to get good photos. The site also had Eriophorum tenellum, so I could never assume the photos of the cottony heads I was taking were this species and not the other, unless the upper bract was extremely long, which isn't always the case. It is probably rare for these to occur together.
