In the shape of the leaves this is the most abnormal i the Se os of the post 
oak which I have seen and, as PALMER suggests, it may possibly be a hybrid 
between Q. annulata and Q. stellata which grow with it. 
¥ QUERCUS STELLATA var. Palmeri, nov. var.—Differing from the 
type in its narrow oblong or slightly obovate 5~7-lobed leaves with 
narrow lobes, in the dense tomentum on their lower surface, and in 
the thicker more closely appressed tomentose scales of the turbinate 
cup. The leaves are deeply divided by wide sinuses into narrow 
acute or rounded, or rarely obliquely truncate lobes and are obtusely 
pointed at apex, rounded at base, pubescent on the upper surface, 
coated below with a thick coat of pale tomentum of fascicled hairs, 
8-9 cm. long and 3-5 cm. wide; petioles tomentose, 5-8 mm. in 
length. Flowers and spring leaves not seen. Fruit sessile or short- 
pedunculate, the cup turbinate with the lower scales often much 
thickened, and 1.2-1.8 cm. in diameter. 
A shrub 2-3.5 m. high, with scaly bark, forming large clumps by under- 
ground stems, the tallest specimens in the center of the clump, the smallest near 
its margins.

\ QUERCUS STELLATA var. rufescens, n. var.—Differing from the 
type in the rusty brown pubescence on the lower surface of the poly- 
morphous leaves and on the branchlets, in the deeper cups of the 
fruit, and in their thicker basal scales. The leaves are pubes- 
cent above throughout the season and thickly covered with close 
rusty brown pubescence on the lower surface. They are 5-6 cm. 
long, 1-1.5 cm. wide, rounded or acute at apex, rounded or
