Scirpeae

Deergrass Trichophorum cespitosum, copyright S. Rae.

Belongs within: Cyperaceae.
Contains: Kyllinga, Scirpus, Eriophorum, Carex.

The Scirpeae are a tribe of sedges in which all flowers are hermaphroditic, and the glumes are spirally arranged and all floriferous except the lowest (Healy & Edgar 1980). Members of the tribe are found in wetland habitats, some in standing water. Phylogenetic analysis indicates that the group is paraphyletic to the genus Carex which produces unisexual flowers.
