Jacksonville there are 3 fruits on the peduncle. The type of Q. geminata is 
described as a shrub or small tree 2-2. 5 m. tall, with a trunk diameter of about 
1scm. Many of the Biloxi trees are 20-25 m. tall, with trunks up to 1 m. in 
diameter. A form of this variety may be distinguished as 
/ QUERCUS VIRGINIANA var. GEMINATA f. grandifolia, n. f.— 
Differing from the variety in its much larger mostly oblong-elliptic 
leaves. Leaves oblong-elliptic to slightly obovate, acute or 
rounded at the apex, narrowed and cuneate or rounded at the base, 
slightly lobed above the middle, pale on the upper surface, tomen- 
tose on the lower surface, 10-12 cm. long and 3-5 cm. wide, with 
thickened revolute margins and conspicuous reticulate veinlets. 
A tree 10-12 m. high, with stout pubescent or tomentose branchlets.

and cuneate at base, occasionally slightly undulate or rarely fur- 
nished, usually above the middle, with occasionally minute teeth 
thin (in June), dark green, glabrous and lustrous on the upper sur- 
face, green, lustrous, and sparingly and minutely pubescent or 
glabrous on the lower surface, 7-12 cm. long and 2.5~-5 cm. wide, 
with prominent midribs, slender primary veins, inconspicuous 
veinlets, and thin margins slightly or not at all revolute; petioles
