Alice Faber Tryon (1920–2009) was an American botanist who specialized in the systematics of ferns and other spore-dispersed plants (pteridology).

[1] She completed her master’s thesis on the taxonomic utility of spore characters in the spikemoss genus Selaginella at the University of Wisconsin in 1945.

Her Doctoral degree she received at Washington University in 1952, where her PhD dissertation was on the diversity and taxonomy of the New World species of Pellaea, a genus of xerically adapted ferns in the Pteridaceae.

[3] At Harvard, they organized and offered an annual New England Fern Conference, which brought students and professors together in an informal and productive setting.

[5] Throughout her career she worked closely with her husband, traveling internationally and frequently publishing together—including their systematic survey of the ferns, with emphasis on tropical America.
