ABSTRACT An inventory of the vascular plants of Kerr Wildlife Management Area, Kerr County, Texas, was conducted from 2006 to spring 2009. The area consists of 21 natural plant community associations and three land use classes. The Sawgrass-Spikesedge-Beakrush-Black Bogrush-Aparejograss Herbaceous Vegetation Association, and Ashe Juniper-Bastard Oak-Plateau Live Oak Woodland Association is reported as new to the state. The checklist reports 719 taxa from 106 families and 410 genera, with 27 of the species being endemic to the state. The largest families were Asteraceae (113 species), Poaceae (109 species), Fabaceae (38 species), and Euphorbiaceae (34 spe- cies). Non-native species comprised 9.04% (65 species) of the flora. Among the more unusual plant records for the area, which consists of a mixture of eastern and western species, are Rhynchospora capillacea, Petrophytum caespitosum, and Echeandia flavescens. Statistics on the adequacy of sampling and a comparative vegetation analysis are also presented.
