The Vascular Flora of Pennsylvania
Author: Ann Fowler Rhoads
Publisher: American Philosophical Society
ISBN: 9780871692078
Category : Botany
Languages : en
Pages : 658
Book Description
This vol. is the first published product of the Pennsylvania Flora Database, created & maintained at the Morris Arboretum of the U. of Pennsylvania. The database has its roots in the work of Edgar T. Wherry, John M. Fogg, Jr., & Herbert A. Wahl, the Atlas of the Flora of PennsylvaniaÓ (Wherry et al. 1979), published by the Morris Arboretum. Over a period of 40 years, Wherry & his colleagues gathered data from the major Pennsylvania herbaria & manually placed a quarter of a million dots on over 3500 maps (Fogg 1944). The Pennsylvania Flora Database retains the emphasis on specimen-based, site-specific data. The checklist of included taxa has undergone extensive review to reflect recent taxonomic & nomenclatural revisions. Questionable specimens have been re-evaluated with the result that several taxa included in earlier works were dropped. Recent discoveries have been added & distribution data has been updated. This vol. also includes collections made in the 1990s in conjunction with the Pennsylvania Natural Diversity Inventory (PNDI), the state heritage program. The maps present the accumulated collection of information for each taxon as represented in the herbaria. Illus., reprinted 1996.
