Notable County records for rolling plains angiosperms of North Central Texas

Based on data from fieldwork in Wichita County on a privately owned ranch located in the Rolling Plains region of Texas, thirty-nine species of flowering plants in 23 families are reported as new distribution and occurrence records for Wichita County, Texas. Twenty-one of these species represent major range extensions for the species in Texas. These new distribution and occurrence records provide baseline floristic data from a region that is poorly known compared to other regions of the state. Most of the new distributions are native but 31% are introduced species. Distribution data is critical for understanding native plant ranges and the spread of introduced species in the state.
