Faculty profile

James Seago

Professor Emeritus


My interests include: plant anatomy and development; root apical meristems; structural adaptations of plants to wetland habitats, esp., invasive vs. native plants; trees and shrubs of Oswego.  Plants I continue to study include, but are not limited to: water lilies of the world, basal angiosperms, Gunnera of the southern hemisphere, plants of the Yangtze River floodplain (China), aquatic and wetland plants around Oswego NY, and the living fossil Ginkgo biloba.  I work with colleagues in the Czech Republic, China, Germany, Canada, Brazil, SUNY ESF, SUNY Oswego, and with former students, and I use the department’s Zeiss LSM laser confocal microscope and Zeiss Stemi2000 dissecting scope.
