A Study of the Flowering Plants of Tulsa County, Oklahoma, Exclusive of the Grasses, Sedges, and Rushes

Abstract

A taxonomic study of the flowering plants of Tulsa County, Oklahoma, exclusive of the grasses, sedges, and rushes, was made from 1955 to 1959. A total of 585 species, representing 99 families and 335 genera, were identified and are on file in the herbarium of the University of Tulsa. The largest families in order of number of species are: Compositae [Asteraceae], 110 species; Leguminosae [Fabaceae], 50 species; Euphorbiaceae, 22 species; Cruciferae [Brassicaceae], 21 species; Rosaceae, 19 species; Scrophulariaceae [Linderniaceae, Orobanchaceae, Phrymaceae, Plantaginaceae, Scrophulariaceae], 18 species; Labiateae [Lamiaceae], 16 species; Polygonaceae, 16 species; and Onagraceae, 15 species. The number of plants found is comparable to similar collections in Muskogee County by Little (1938) and in Pontotoc County by McCoy (1958). The plant list of Tulsa County may be increased by further study.
