As family treatments are completed for the New Manual, these are being made available as downloadable PDFs. The New Manual is a multi-year project by the New York Botanical Garden to fully revise and update the classic Manual of Vascular Plants of Northeastern United States and Adjacent Canada, Second Edition, by Gleason and Cronquist (1991, NYBG Press), in order to enable identification of all plants growing spontaneously in a vast region comprising portions or entirety of 22 states and 5 Canadian provinces (see map here). These family treatments are indispensable to all those interested having the most up-to-date information for this region of North America's rich botanical resources, serving the vascular plant reference needs especially of students, conservationists, wildlife managers, educators, gardeners, and citizen scientists.

"A brand new flora of vascular plants from The New York Botanical Garden is available as digital PDF downloads and will soon be printed as a complete hardbound version! The area covered includes Nova Scotia, Prince Edward Island, New Brunswick, and southern Quebec and Ontario. The New Manual of Vascular Plants of Northeastern United States and Adjacent Canada is under preparation, representing a revised enlarged update of the 1991 classic Gleason & Cronquist Manual, with approximately 20% more species. This is good news for many different biologists. The botanical treatments will be particularly useful for American and Canadian botanists as well as other scientists, naturalists, ecologists, foresters, conservationists, and students in all fields of natural history, as well as public or private organizations involved in environmental and plant protection. In contrast to the 1991 Manual, plant families are treated by specialists of these groups. Because so much information has been added in recent years, this new edition is very welcome, and the editors and the numerous authors deserve praise."- Jacques Cayouette, Ph.D., Research Scientist, Agriculture and Agri-Food Canada; Assistant Curator, Department of Agriculture Ottawa Herbarium
The major focus of my research is the floristics of eastern North America. Specifically, my research entails study of the identification, geographic distribution, frequency, ecology, and conservation of plants growing wild in this region. The chief aim of this research is revision of Gleason and Cronquist's Manual of Vascular Plants of Northeastern United States and Adjacent Canada (The New York Botanical Garden Press, 1991). The Gleason & Cronquist Manual is the latest in a rich tradition of books on plants of northeastern North America published by New York Botanical Garden staff. Since Nathaniel Lord Britton published his Illustrated Flora in 1896, the goal of these books has been to enable the user to correctly identify plants growing in the wild in a vast region. The geographic coverage of the Gleason & Cronquist Manual encompasses all or portions of 22 states of the U.S.A. and five Canadian provinces. Major advances in botanical science since the last edition of the Manual mean the time is ripe for a revision. In addition, I conduct research in plant systematics. Much of this research is devoted to revisionary systematics of sedges, particularly the genera Carex and Rhynchospora (Cyperaceae). Carex, with about 2000 species, is the largest genus of flowering plants in North America and one of the world's largest genera. Data from field, laboratory, and herbarium studies permit me to describe new sedge species, reconstruct their phylogenies, and improve their classifications. I am especially keen on utilizing phylogenetic trees to understand sedge morphology, chromosome number variation, and biogeography. I also study the systematics of the Western Hemisphere Pitcher Plants (Sarraceniaceae), carnivorous plants with pitcher-like leaves functioning as traps. Despite their inherent interest and popularity in horticulture, pitcher plants remain poorly understood. I am applying novel approaches to study their systematics. Robert F.C. Naczi's Author Page
