Rolla Milton Tryon Jr. (August 26, 1916 – August 20, 2001) was an American botanist who specialized in the systematics and evolution of ferns and other spore-dispersed plants (pteridology). His particular focus and interest lay in two areas, historical biogeography of ferns and the taxonomy of tropical American ferns.
