Q. Similar to group P except that stem and base are straight. They are symmetric and well finished, vary more in size than those of the last group, being from 1¼ to 4¼ inches long, the others not reaching either of these limits.
The type ([figure 216]) comes from Knox county, Ohio, and other specimens from Miami valley and central Ohio; Keokuk, Iowa; northeastern Kentucky; Kanawha valley; eastern and western Tennessee; eastern, southeastern, and southwestern Arkansas; eastern and southwestern Wisconsin; northwestern Georgia; and southwestern Illinois.
R. Edges generally convex, sometimes straight; base straight or convex, only rarely concave; shoulders usually square, sometimes rounded; stem expanding by straight lines. From less than an inch to 3½ inches long, mostly about the medium.
The form, which resembles that shown in [figure 216] in a general way, is widely distributed, its range including Keokuk, Iowa; Miami and Scioto valleys, Ohio; Bibb county and Savannah, Georgia, as well as the northwestern part of the state; eastern Tennessee; Kanawha valley, West Virginia; southeastern and southwestern Arkansas; southwestern Illinois, and Brown county in the same state; northeastern Kentucky; southern and southwestern Wisconsin; western and central North Carolina; and northeastern Alabama.
S. Differing from group Q in having the blade short, stem long (in some cases longer than blade), and only slight shoulders. Base somewhat convex in a few specimens; from an inch to 2¼ inches in length. From Kanawha valley; northwestern Georgia; Miami and Scioto valleys, Ohio; southwestern Arkansas; southern Wisconsin; and northeastern Alabama.
Beginning with those of group N and ending with those last described, all the best worked and most finely finished specimens are from Kanawha valley, West Virginia; northeastern Kentucky, and the central and southern parts of Ohio.
T. Convex edges; square shoulders; slender; very long and slender tapering or straight stem, coming almost to a point at the base. Illustrated in [figure 217] (from Kanawha valley). Others are from central North Carolina; Kanawha valley; southwestern Arkansas; and Catahoula parish, Louisiana. The specimens from the two latter districts have the stem wider and less pointed than the others.
