COMMELINACEAE, the Dayflower & Spiderwort Family by Robert B. Faden & Christopher R. Hardy. Keywords: Commeliaceae, Commelina, Murdannia, Callisia, Tradescantia, Flora, Floristics, North America. http://dx.doi.org/1021135/893275471.047.
In the New Manual of Vascular Plants of Northeastern United States and Adjacent Canada the Commelinaceae is represented by eleven species. 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
