Quercus breviloba Sarg.

Leaves oblong to oblong-obovate or elliptic, rounded or acute at apex, cuneate or rounded at base, entire, undulate, slightly lobed with rounded or acute lobes, or 3-lobed, when they unfold covered above with fascicled hairs and tomentose below, and at maturity green, glabrous and lustrous above, green and pubescent below on lower branches, often pale or hoary tomentose on upper branches, 1¼′—2½′ long, ½′—1¼′ wide; petioles covered when they first appear with fascicled hairs, soon glabrous, ¼′—½′ in length; on vigorous branchlets sometimes thinner, glabrous, divided into broad rounded lateral lobes, gradually narrowed and cuneate at the long base, 4′ long and 2½′ wide. Flowers: staminate in pubescent aments 1′—2′ long; calyx deeply divided in villose rounded lobes, shorter than the stamens; anthers red; pistillate on tomentose peduncles, their scales rounded, tomentose; stigmas red. Fruit solitary or in 2 or 3-fruited clusters, sessile or short-stalked, oblong-ovoid to ellipsoidal, slightly narrowed and rounded at apex, light yellow-brown and lustrous, ¾′—1′ long, ⅓′—½′ in diameter; inclosed for about a quarter of its length in the cup-shaped cup, tomentose on the inner surface, covered with acute tomentose scales somewhat thickened and closely appressed below the middle of the cup, their tips chestnut-brown, free and often glabrous.

A tree, 20°—30° tall with a trunk rarely more than 1° in diameter, small spreading often slightly pendulous branches forming a round-topped head, and slender branches covered when they first appear with fascicled hairs, soon becoming glabrous and gray or grayish brown; the large stems often surrounded by a ring of smaller stems produced from its roots; more often a shrub than a tree spreading into broad thickets. Winter-buds ovoid to ellipsoidal, acute, ⅛′—¼′ long, with closely imbricated chestnut-brown puberulous scales ciliate on the margins. Bark thick, rough, deeply ridged.

Distribution. Dry limestone hills and bluffs; central and western Texas, from the neighborhood of Dallas, Dallas County, and Palo Pinto County to Kendall, Kerr, Brown, Bandera, Real and Menard Counties.

Quercus breviloba Sarg. in part.

Leaves thin, obovate to elliptic, entire, 3-lobed toward the rounded or acute apex or irregularly laterally lobed, the three forms appearing on different branches of the same tree, on lower branches usually lobed, dark green and lustrous above, often green and glabrous below, sometimes 6′ or 7′ long and 3′ or 3½′ wide, on upper branches mostly entire, white and pubescent or tomentose below, 2½′—3′ long, ½′—1½′ wide; falling late in the autumn; petioles glabrous, ⅓′—¼′ in length. Flowers: staminate in slender villose aments 3′—4′ in length; calyx deeply divided into acute villose lobes shorter than the stamens; pistillate on a short tomentose peduncle, the linear acuminate bract and involucral scales hoary-tomentose; stigmas red. Fruit solitary or in pairs, short-stalked or nearly sessile; nut ovoid, or slightly obovoid, rounded or rarely acute at apex, nearly truncate at base, pale chestnut-brown, lustrous, ½′—⅔′ long, ⅓′—½′ thick, barely inclosed at base in the thin, shallow saucer-shaped cup, pale tomentose on the inner surface, and covered with small acuminate closely appressed tomentose scales slightly thickened on the back.

A tree, often 60°—90° high with a tall trunk 2°—3° in diameter, comparatively small branches, the lower horizontal, the upper ascending, forming a dense round-topped handsome head, and slender pale gray-brown branchlets covered when they first appear with fascicled hairs, soon glabrous, or puberulous during their first season, and darker in their second season. Winter-buds ovoid, acute, ¼′—⅓′ long with dark chestnut-brown rounded scales ciliate on the margins. Bark thin, light gray or nearly white and broken into thin loosely appressed scales.
