Download or read book The Vascular Flora of Pennsylvania written by Ann Fowler Rhoads and published by American Philosophical Society. This book was released on 1993 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "The Flora of Missouri project, directed by Garden Curator, Dr. George Yatskievych, is an ongoing effort to update and compile information on the state's flora. It began in 1987 as a joint effort of the Missouri Botanical Garden and the Missouri Department of Conservation. One of its main goals is a three-volume revision of former Missouri Botanical Garden curator Julian A. Steyermark's 'Flora of Missouri', first published in 1963. Missouri's ever changing plant diversity, the shifting distributions of its plant species, and the many new records of plants in the state have necessitated an expansion of Steyermark's original publication into three volumes."--
