A.F.Tryon
Alice Faber Tryon (1920–2009) was an American botanist who specialized in the systematics of ferns and other spore-dispersed plants (pteridology). She had two general areas of interest in her work, first incorporating the use of spore surface patterns into the understanding of fern diversity and systematics, and second the fern family Pteridaceae. Biography Alice Faber Tryon was born Alice Elizabeth Faber in Milwaukee, Wisconsin, on August 2, 1920, to Arthur and Laura Bindrich Faber. Alice Tryon completed her Bachelor's degree in 1941 at Milwaukee State Teacher’s College (now the University of Wisconsin). 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 Pter ...

Eriosorus
''Jamesonia'' is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. It now includes the formerly separate genus ''Eriosorus''. Description Species of ''Jamesonia'' are terrestrial or grow on rocks. They vary considerably in their detailed morphology. The rhizomes are short, dark brown, and creeping, with a more or less dense covering of hairs and bristles. The fertile and infertile fronds are similar. Species show one of two different frond morphologies, related to habitat. These were formerly used to distinguish ''Jamesonia'' and ''Eriosorus'', but do not correspond to the evolutionary history of the species. Species with "''Jamesonia''-type" morphology have many fronds with short, often leathery Glossary of botanical terms#pinna, pinnae, and are associated with exposed habitats. Species with "''Eriosorus''-type" morphology have fewer fronds with longer, thinner pinnae, and are associated with more sheltered areas including cloud forests. The stalks (Petiol ...

Pellaea (plant)
''Pellaea'' is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. The genus name is derived from the Greek word πελλος (''pellos''), meaning "dark," and refers to the brown stems. Many members of the genus are commonly known as cliffbrakes. They primarily grow in rocky habitats, including moist rocky canyons, slopes, and bluffs. Distribution Ferns in this genus are most abundant and diverse in the southwestern United States south into Andean South America, central and southern Africa, and eastern Australia to New Zealand. Description These ferns typically have creeping rhizomes and pinnately to bipinnately compound leaves lacking prominent scales or trichomes on the blades. Like most members of Pteridaceae, they have marginal sori protected by a false indusium formed from the reflexed leaf margin. The distinction of ''Pellaea'' from the typically hairier or scalier ''Cheilanthes'' has proven difficult, with some members being of uncertain affinity, li ...

Tryonia (plant)
''Tryonia'' is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are native to the east of Brazil and to Uruguay. The genus was circumscribed by Eric Schuettpelz, Jefferson Prado and Alyssa T. Cochran in PhytoKeys vol.35 on page 35 in 2014. The genus name of ''Tryonia'' is in honour of Alice F. Tryon (1920–2009), who was an American botanist (mainly pteridology). She examined the taxonomy of the fern genera ''Jamesonia ''Jamesonia'' is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae.

University Of Wisconsin–Milwaukee Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Middl ...
