jamesonia การใช้

• The name honored Tryon for her fern systematics and published taxonomic revisions of both Jamesonia sensu stricto and Eriosorus.
• In 2014, Tryonia was described as a new taenitidoid fern genus segregated from Jamesonia and Eriosorus ( Pteridaceae ).
• "Jamesonia " species are also found in cooler regions, but extending from Mexico to Bolivia and upland Brazil.
• The two genera are being temporarily considered here under " Jamesonia ", because 1 ) this is the older genus name, and 2 ) the core genus forms a clearly defined monophyletic group considered by itself, while there is no such clear clade for " Eriosorus ".
