— Couplets have not yet been developed beyond the last choice you made (use the back arrow to return to that choice). Our Key to the Grasses and Sedges of Hawai‘i covers 118 taxa (species, subspecies, and varieties) of grasses and 24 taxa of sedges found in the Islands. The majority of grasses and sedges found below about 760 m (2500 ft) elevation, other than rare or newly introduced ones, should key out. You might start over and (if appropriate) note lists at the botttom of "genus" pages for possibilities not yet covered in the key.
Buffel grass (Cenchrus ciliaris) in anthesis.
