ingly broadly oblanceolate leaves, which except on vigorous shoots are 
entire and acute. The leaves when entire resemble those of Q. lauri- 
folia, although when 3-notched on vigorous shoots they are charac- 
teristic. Many of the trees in eastern Texas and adjacent parts of 
Louisiana have only entire foliage, and for such, which without the 
distinctive fruit are with difficulty separated from large-leaved forms 
of Q. laurifolia, there 1s suggested the name: 
Q. ARENICOLA integran. var. This differs from the type in having 
all the leaves on the tree entire; fruit as in type. Sandy bluffs along 
Sabine River, Texas, and Louisiana (type from Haddon Ferry, La. 
No. 1100). 
Quercus oBTUsA (Willd.) Ashe. Torreya 18: 4, 72 (May 8, 1918.)

307 (1887). Houba gives an excellent illustration showing character- 
istic foliage of this tree, but mistakes it for the typical laurifolia. This 
tree is common throughout the entire coastal plain region of the South- 
ern States and has been generally confused with Q. laurifolia. In 
Texas it occurs as far inland as Harrison County, in Louisiana to 
Sabine Parish and in Alabama as far north as Tuscaloosa, where it 
has been extensively planted as a shade tree and where it is regarded 
as being Q. laurifolia Mx. It seems to be as distinct from Q. lawrifolia 
in southern Louisiana where the two are frequently associated as it 
is in Georgia and North Carolina. It is locally esteemed for its timber 
which is regarded as equal to that of Q. laurifolia, the best of the water 
oak group. 
Q. optusa obovatifolia (Sarg.) n. c. Q. rhombica var. obovatifolia 
Sarg. l. c. Specimens of this variety, which differs from the type 
only in its spatulate leaves with rounded apices, were noted in Cald- 
well Parish, Louisiana. On one specimen the acorns were oblong in 
place of ovoid. 
Quercus moultonensis n.n. Q. hybrida, Houba, Chênes de l'Am. 
Sept., 310 (1887). Q. phellos L. x Q. shumardii Buckl. A number of 
fine specimens of this were noted in the Moulton Valley of the Tennes- 
see River in Lawrence County, Ala., where both of the supposed 
parents are common. The leaf blades are oblong, with 5-7 mostly 
entire spreading or ascending lobes, and with tuft of pubescence in
