cuneate at base, slightly or deeply lobed with 2-4 pairs of rounded 
lobes, or undulate or rarely entire; on vigorous shoots they are 
oblong-obovate with the broad upper lobes of the leaves of the post 
oak, 6-7 cm. long and 3.5—4 cm. wide; petioles densely pubescent, 
4-5 mm. in length. Leaves collected in the spring and flowers not 
seen. Leaves on some individuals oblong-obovate, broad or grad- 
ually narrowed and rounded at apex, cuneate at base, slightly 
divided into two or three pairs of broad rounded lobes, 5—7.5 cm. 
long and 3.5~4.5 cm. wide; on others oblong-obovate, 7-lobed, the 
lateral lobes of the upper pair rounded or truncate at apex, or 
occasionally 5-lobed, the truncate upper lateral lobes like those of 
the type. Fruit sessile or short-pedunculate; cup turbinate, rusty 
pubescent, the lower scales often much thickened, inclosing one- 
half to three-quarters of the nut, and 1.2—1.8 cm. in diameter. 
Shrubs 4-5 m. high, with scaly bark, spreading by underground stems into 
large thickets, and slender branchlets thickly covered during their first two 
seasons with rusty brown pubescence; rarely small trees.

Texas.—Big Springs, Howard County, E. J. Palmer, July 9 and October 
23, 1917 (nos. 12489, 13063, 13064, with oblong-obovate leaves with rounded 
or truncate upper lobes. ~ “In sandy soil this shrubby post oak grows in large 
clumps to a maximum height of 4 m.; it suckers freely and is a very conspicuous 
feature of the flora on account of its peculiar growth, dark green foliage, and 
greater height among large areas of 0. Mohreana)”; Fort Chadburn, Coke 
County, E. J. Palmer, July 7, 1917 (no. 12462, ‘‘shrubs or small trees 2-3 ™. 
high’’); dry gravel hills, Sweetwater, Nolan County, Texas, E. J. Palmer, 
Onan 21, 1917 (no. 13054, with narrow slightly lobed or undulate leaves; 
‘a tree 6-8 m. high; branches stout, rigid; bark rough”). 
The following varieties with glabrous or nearly glabrous branch- 
lets can be distinguished: 
QUERCUS STELLATA var. MARGARETTA Sargent in Trees and 
Shrubs 2:219. 1913.—Q. minor var. Margaretta Ashe, Jour. Elisha 
Mitchell Sci. Soc. 11:94. 1894; Q. Margaretta Small, FI. South- 
eastern U.S. 355. 1903.—Differing from the type in the usually 
rounded lobes of the leaves soon glabrous on the upper surface, 
in the less dense sometimes nearly deciduous pubescence on the 
lower surface, and in the slender glabrous reddish branchlets.
