【實用教育app】TwigID|最夯免費app-綠色工廠好玩App

Winter twig keys to common, fully deciduous trees and phanerophyte shrubs of the North Carolina eastern Piedmont. This app was developed primarily for use in a Local Flora course at North Carolina State University. As others may find it useful, we are releasing it here. Please note that the key is not comprehensive for all trees in the Piedmont area, but limited to the common species. Taxa included in the keys are those which the senior author has encountered commonly during field trips in the eastern Piedmont throughout the last thirty years. Keys are based on the author’s observations of living material and herbarium specimens in the North Carolina State University Herbarium.

The keys benefited from an unpublished key written by Dr. James Hardin and from keys presented by Brown and Brown (1972: Woody plants of Maryland, Port City Press) and Preston and Wright (1988: Identification of Southeastern Trees in Winter, NC Agr. Exp. Sta. AG-42). Nomenclature and taxonomic concepts follow Weakley (2010: Flora of the southern and mid-Atlantic states). A list of excluded species is included in the app. Images were captured by Dr. Jon Stucky and Dr. Alexander Krings, with additional contributions by Will Cook (Duke University), Dr. Paul G. Davison (University of North Alabama), and Jeffrey Pippen (Duke University).
