Vascular Flora of the Deep Fork River in Okmulgee, Creek and Okfuskee Counties, Oklahoma

Abstract

This paper reports the results of an inventory of the vascular plants on the Deep Fork River in Creek, Okfuskee, and Okmulgee counties. A total of 500 taxa of vascular plant species in 293 genera and 99 families was collected. The largest families were the Poaceae (77 species), Asteraceae (58), Cyperaceae (46) and Fabaceae (36). One hundred and thirty-five species were annuals, 11 biennials, and 354 perennials. Seventy-four woody plant species were collected. Thirty-eight exotic species (7.6% of the total flora) were collected. No federally listed threatened or endangered species were found, but eight species tracked by the Oklahoma Natural Heritage Inventory were present.
