1895 (not Buckley).—Q. Schneckii Britton, Man. 333. 1901.— 
Differing from the type in the cup-shaped cups of the fruit covered . 
with thin or rarely toward the base with much thickened scales. 
This is the more common form in the Mississippi valley, and although not 
rare in the Gulf and south Atlantic states, it is less common there than the 
type. Forms with thickened cup-scales I have seen only on specimens collected 
by T. G. Harbison “from large wide-spreading trees in low rich soil in river 
bottoms north of Vicksburg, Mississippi,’ October 27, 1916. 
QuERcUS coccINEA Moench.—An interesting form of the 
scarlet oak may be distinguished as 
/ QUERCUS COCCINEA var. tuberculata, n. var.—Differing from 
the type in the much larger fruit, with cup-scales more or less thick- 
ened below the middle of the cup-shaped or turbinate cup, those 
of the upper row thin and forming a distinct marginal ring. 
Bluffs of the Alabama River, near Berlin, Dallas County, Alabama. C. 5. 
Sargent, April 19, 1915; R. S. Cocks, August 27, 1915 (no. 912), September 1, 
1915 (no. 940), August 24, 1916 (no. 8098, type). 
In the habit of this oak, which is a large tree, in the bark of the trunk, and 
in the leaves there is nothing to distinguish it from the typical Q. coccinea. 
The location is exceptional, for this tree ranges south along the Appalachian 
Mountains and their foothills, and has not been found before east of the Missis- 
sippi River south of northern Georgia and northeastern Mississippi. In other 
parts of the country the cup-scales of Q. coccinea sometimes show a tendency 
to thicken, although in a less degree than those on these Alabama trees; and 
I have seen specimens with such thickened scales from a tree growing near New 
Bedford, Massachusetts, and on one from Tennessee without exact locality. 
QUERCUS RUBRA L.—The specimen on which Linnaeus based 
his Q. rubra (Q. falcata Michx.) came from Virginia and has ovate 
to obovate long-stalked leaves narrowed and rounded or cuneate 
at base, with a long acuminate entire or slightly lobed terminal lobe 
and 2 or 4 large acuminate lateral lobes pointing forward. Leaves 
of this form, which must be considered the typical form of Q. rubra, 
are pubescent early in the season on the upper surface, becoming 
nearly glabrous before autumn. The lower surface is covered 
more or less thickly with rusty or pale pubescence. This is 
the common form of the southern red oak in the Atlantic states 
north of Virginia. On some trees leaves occur which are broadly
