Is anyone familiar with any good online plant keys? Of particular interest would be a key that could be used when the plant is not in flower.

Thanks,
Matt Blake

I am not aware of any online keys (although sites like Missouri Botanical Garden may have one). However, Flora ID Northwest produces computer driven interactive keys that use many different plant characteristics such as flower, fruit, stem, leaves, roots, etc. They have produced mostly regional keys. I have used the one for Minnesota. Check out their website for other keys at http://www.xidservices.com/FID

You can pull a good deal of the Flora of North America work pff the web.

You can get a review copy of Alan Weakley's Flora of the Carolinas, Virginia, and Georgia
from the web at: http://www.herbarium.unc.edu/flora.htm

Common,Woody, Piedmont and Coastal Plain, Wetland Plants of the Carolinas, by Stucky, J.M., A. Krings, A.L. Belskis, J.M. Cianchetta, E.S. Niven, and A.B. Russell. is available at
