Beaver Dam Wash Vascular Plant Lists Stanley L. Welsh 13 February 2007

There are more than 400 species of plants Araliaceae known from the Utah portion of Beaver Dam Hedra helix Wash, including the Beaver Dam Slope and the Asclepiadaceae Beaver Dam Mountains. The first list is of those Asclepias erosa Torrey whose distribution is principally in Beaver Dam Wash. Mainly they are indigenous species, but Bignoniaceae some are cultivated species (*) whose distribution Campsis radicans (L.) Seemann* in Utah is confined to Washington County; a few Chilopsis linearis (Cavanilles) Sweet are weedy species (**). The unique species total 174 and represent 43.5% of the total species Boraginaceae known for the Wash, and about 5.6% of the Cryptantha barbigera (A. Gray) Greene! indigenous flora of the state. Cryptantha dicipiens (M. E. Jones) Heller A second list of riparian plant species is Cryptantha dumetorum Greene presented following the first list. The 42 species Cryptantha racemosa (S. Watson) Greene from the second list represent 10.5% of the known Cryptantha virginensis (M. E. Jones) Payson flora of the wash. Both lists are organized Pectocarya platycarpa (Munz & Johnston) alphabetically by family, genus, and species. Munz & Johnston! Pectocarya recurvata Johnston! Coniferous plants: Pectocarya setosa A. Gray! Tiquilia canescens (Hooker) A. Richardson! Ephedra fasciculata A. Nelson Buddlejaceae Ferns and relatives: Buddleja utahensis Coville
