Couplets have not yet been developed beyond the last choice you made (use the back button to return to that page). Our Key to the Grasses of Hawai‘i and Guam covers 171 taxa (species, subspecies, and varieties) of grasses (over 90%) and 87 taxa of grasses found on Guam (nearly 67%). The majority of grasses found in Hawai‘i below about 760 m (2500 ft) elevation should be identifiable with the key; and species are being added all of the time. If you reached this page, you might START OVER and check for a list at the bottom of each page giving species not covered in the key.

The author would appreciate constructive input where problems are encounterted in the key or a specimen in hand cannot be correctly identified using the key. You may send comments to the author (guinther@hawaii.rr.com). If you encounter a grass you cannot identify with this key you may place it in an envelope (there must be an inflorescence, but specimen can be dried) with a note that includes location and island and your email address for a return answer (if I can identify it). Mail the specimen to "E. Guinther, 45-309 Akimala Pl. Kāne‘ohe, Hawai‘i, 96744".
