The above map[1] gives the larger natural areas of the state. The prairie regions afford the most profuse display of wild flowers. In the wooded area of East Texas, the shortleaf pine is abundant in the northern part, the loblolly in the southwestern part, and the longleaf pine in the southeastern part of the area, while hardwoods are found in the river bottoms. The chief trees in the post oak strip are post oak and black jack oak. Among the mountain cedars, live oaks and Spanish oaks, so common in the limestone hill region, may be found scattered trees and shrubs of the chaparral. The chaparral region is often broken by prairies but in some places is densely covered with shrubs and small trees which are usually thorny. The mesquite is abundant in this region and is more or less scattered throughout the prairie regions.
