Support the Plant Atlas

The mission of the Institute for Systematic Botany is to promote basic research in plant systematics and to coordinate research, education, and service programs in plant systematics at USF.  The ISB staff maintain the Atlas of Florida Vascular Plants, a comprehensive source of information of distribution and nomenclature for the more than 4,200 native and naturalized vascular plants in the state of Florida. The Atlas of Florida Vascular Plants provides information to public agencies, private companies, non-profit organizations, schools, and individuals around the state for environmental decision making and education.

As a product of a not-for profit institute within the University of South Florida, the Atlas is funded through contracts with a variety of agencies. We are therefore subject to inevitable fluctuations of interest and economics by these agencies who cannot guarantee our continued maintenance.  You can help, however, because the Institute for Systematic Botany is eligible to receive donations via the USF Foundation. Your valued contribution will help fund the mission of the ISB and the continuation of the Atlas of Florida Vascular Plants website. If you are interested in making a tax-deductible donation, please contact Richard P. Wunderlin, ISB Director, at
