1918] SARGENT—QUERCUS 437 
In the woods 12 miles west of Opelousas, Louisiana, in wet, often 
inundated ground, there are large post oaks with square lobed leaves 
glabrous on the upper surface in April, tomentose branchlets, and 
pale scaly bark. These trees most resemble, except in their bark, 
the typical post oak, but there is not now sufficient material avail- 
able to make it possible to treat them as a variety. The following 
varieties with tomentose branchlets can be distinguished: 
v QUERCUS STELLATA var. Boyntonii, n. var.—Q. Boyntonii 
Beadle, Bilt. Bot. Studies 1:47. 1901.—Differing from the type in 
the shape of its obovate leaves mostly 3—-5-lobed toward the apex 
with small rounded lobes, and in their yellowish brown pubes- 
cence. The leaves are oblong-obovate, gradually narrowed and 
cuneate or rarely rounded at base, and 3~5-lobed above the middle 
with broad rounded lobes; when they unfold they are stellate- 
pubescent above and tomentose below with a thick coat of rusty 
brown stellate hairs, and at maturity are subcoriaceous, dark green, 
lustrous and glabrous on the upper surface, tomentose on the 
lower surface, 9-12 cm. long and 4—7 cm. wide; petioles pubescent, 
5-10 cm. in length. The cups of the fruit vary from cup shape to 
turbinate and their scales are thin and sometimes much thickened 
toward the base of the cup and are hoary tomentose. 
A shrub or small tree spreading into thickets, 1-5 m. tall, with stems 
covered with rough dark gray furrowed bark, gray-brown branches, and 
branchlets coated during their first season with yellowish brown tomentum, 
and glabrous or slightly pubescent in their second season. In the shelter of 
narrow glades on the summit of Lookout Mountain above Gadsden and 
- Attala, Etowah County, Alabama. 
The dwarf habit of this little oak is due probably to the exposed position 
and high altitude where it grows. It is best distinguished from other forms 
of dwarf post oaks by the color of the yellow-brown pubescence on the leaves 
and branchlets, for the fruit is not different from that of the typical post oak, 
and the shape of the leaves is similar to that of many post oak leaves with 
rounded lobes. 
/ QUERCUS STELLATA vat. attenuata, n. var.—Differing from the 
type in the oblong to oblong-obovate narrow leaves 3-lobed at 
the apex with small, usually rounded lobes, the lateral rarely trun- 
cate at the apex, below slightly undulate or lobed with one or 
with two small lobes and gradually narrowed to the cuneate base;
