lobe, and 3-lobed toward the apex, the terminal lobe gradually 
narrowed and rounded at apex or sometimes divided into 3 small 
rounded terminal lobes, the lateral lobes gradually narrowed, 
rounded and entire, or broader, nearly truncate and slightly 2-lobed 
at apex; when they unfold thickly covered above with fascicled 
hairs and below with thick persistent tawny pubescence; at 
maturity thick, dark green, lustrous and scabrate on the upper sur- 
face, 8-12 cm. long and 4-6 cm. wide across the lobes, with stout 
midribs and two prominent veins running to the ends of the lobes, 
and thickened slightly revolute margins; petioles covered when 
the leaves first appear with pubescence, soon mostly deciduous, and 
1o-12 mm. in length. Flowers and fruit as in the species. 
A tree 20-25 m. tall, with a trunk sometimes 1 m. in diameter, covered with 
pale bark separating into thin usually appressed scales, stout branches forming 
a narrow round-topped head, and slender branchlets dark red and sparingly 
stellate-pubescent when they first appear, and red-brown or gray-brown and 
slightly pubescent or nearly glabrous later in the season. Winter buds ovate, 
obtusely pointed, with red-brown pubescent scales.

there are 8 trees of this distinct variety of the post oak. 
“ QueRcuUS MUEHLENBERGII var. Brayi, n. var—Q. Brayi 
Small, Bull. Torr. Bot. Club 28:358. 1901.—The chestnut oak of 
western Texas differs from Q. Muehlenbergii Englem. only in its 
larger fruits, which are sometimes 3 cm. long with cups 1.5 cm. 
deep and 2.5 cm. in diameter, with slightly more thickened scales. 
Such fruit is found on trees on the Edwards Plateau where this oak is not 
rare in low ground in the neighborhood of streams. The type tree is a large 
specimen on the bottom lands of a small stream at Lacey’s Ranch near Kerr- 
ville, Kerr County. Farther west the fruit is smaller, and on the Guadalupe 
Mountains, which is the western known limit of the range of this chestnut 
oak, the fruit is small, with cups not more than 1.5 cm. in diameter. 
~ QUERCUS UTAHENSIS var. submollis, n. var.—Q. submollis Ryd- 
berg, Bull. N.Y. Bot. Garden 2: 202. 1901.—Differing from the type 
only in the thinner scales of the cup of the fruit. 
Q. submollis as a species was based on the thin scales of the cup of the 
fruit. The cup-scales of Quercus do not, however, afford a valuable character
