wooded regions in many localities from Region 16 westward. Yaupon, crooked bush, agarita, Mexican cedar and other sorts are all common, the last two being confined mostly to limestone soils. Grasses prominent in all the oak-hickory regions are: triple-awn, crab-an especially vicious weed in cultivated fields-Triodia, bluestems, bromes, gramas, and buffalo on tighter alkaline soils, bur-grass, sprangle-top, needle-grass, panics, hurrah, love-grass, dropseed, Bermuda and some Johnson grass. A wide variety of sedges also occurs, especially in damper situations, as in wet weather ponds and around their edges. Families of wild flowers are much the same as those found in other regions, but in many places having specific representatives, which give a characteristically different appearance to the landscape in blossom. Nuttall's chickweed, pilose and slender Phlox, lance-leaved and deep red Gaillardia, red paint-brush, cottony Froelichia, umbrellawort, daisies, bitterweed (Helenium spp.) goat weed (Croton spp.) and many others contribute their specific bits to the general oak-hickory wild-flower landscape.

The regions are all well adapted to corn and cotton and to such truck crops as peas, peanuts, tomatoes, sweet potatoes, sorghum, watermelons and others. The land is not as productive of the staple field crops as is that of regions 7, 12, 13, and 18; but it makes up, in a measure, by being much more productive of those crops which enable a farmer to "live at home."
