ovate acuminate lobes shorter than the stamens; pistillate flowers not seen. Fruit solitary 

 or in pairs, sessile or raised on a stem up to \' in length; nut ellipsoidal or oblong-ovoid, 

 rounded at apex, slightly narrowed and nearly truncate at base, light chestnut-brown and 

 lustrous, f'-l' long, \'-\' in diameter, the base inclosed in the thick, cup-shaped to 

 rarely saucer-shaped cup, tomentose on the inner surface, covered with acute much 

 thickened pale tomentose scales. 



A tree, 30-45 high, with a trunk 20'-30' in diameter, heavy erect and spreading branches 

 and slender branchlets villose when they first appear, soon becoming glabrous and red- 

 brown or gray during their second season; often a tall shrub with numerous stems. Win- 

 ter-buds ovoid, acute, \' long, with chestnut-brown scales ciliate on the margins. Bark

Distribution. Rocky banks of streams, the steep sides of canons and on limestone 

 bluffs; common in the southern and southwestern parts of the Edwards Plateau, western 

 Texas (Kendall, Kerr, Bandera, Uvalde, Menard, Kemble, Real and Edwards Counties); 

 easily distinguished in the field by the peculiar smoky or waxy appearance of the foliage.

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 ma- 

 turity green, glabrous and lustrous above, green and pubescent below on lower branches, 

 often pale or hoary tomentose on upper branches, 1|'-2|' long, |'-lj' wide; petioles 

 covered when they first appear with fascicled hairs, soon glabrous, \'-\' in length; on vig- 

 orous branchlets sometimes thinner, glabrous, divided into broad rounded lateral lobes, 

 gradually narrowed and cuneate at the long base, 4' long and 2^' wide. Flowers: stami- 

 nate in pubescent aments l'-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, f'-l' long, \'-%' 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 chest- 

 nut-brown, free and often glabrous.
