Carex Working Group

Carex hystericina

The Carex Working Group formed in 1993 out of a common interest in the genus Carex (sedges) and to work toward the following goals:

The Carex Working Group annotated all Oregon Carex in the OSU herbarium and many of the other herbaria around the state. With the aid of Dr. Jon Kimmerling (Geosciences), Manuela Huso (Forest Science), and the Oregon Flora Project they produced the Atlas of Oregon Carex which contains distribution maps for all Oregon Carex taxa. More recently, they wrote the well-illustrated Field Guide to the Sedges of the Pacific Northwest, published by OSU Press. Members of the Carex Working Group have described a new species that occurs in southern Oregon (Carex serpenticola) and have written keys to regional Carex, grasses, Juncus, Luzula, and Salix keys. In addition, they provide input to the Oregon Biodiversity Information Center (ORBIC) on rare graminoid taxa of Oregon.

Some of the original Carex Working Group members incorporated as a small botanical consulting firm with the same name. More information can be obtained by contacting any of the current members:
