sand hills it is rarely more than ro m. tall and usually much smaller, 
with a short trunk and rigid erect branches which form a rather 
open and unsymmetrical head, but in the richer moist soil of the 
flats covered by pine woods in the center of the Florida peninsula 
it is often a tree 20-25 m. high. with a tall trunk and a wide head of 
gracefully drooping branches. The leaves of Q. cinerea are usually 
entire, but on the ends of branches of occasional trees leaves occur 
which are oblong-obovate and more or less lobed at the acute or 
rounded apex, or are divided into short lateral acuminate lobes. 
This form has been described as 
QUERCUS CINEREA $8 DENTATO-LOBATA A. DC. Prodr. 16°:73. 
1864. 
Specimens of such leaves I have seen only from Lumber City and Climax, 
Georgia, San Mateo and Orlando, Florida, and from Cottondale and Mount 
Vernon, Alabama, where they were collected in May and November 1917 
by T. G. Harbison; from Chestnut, Natchitoches Parish, Louisiana (Palmer 
no. 9471); and from San Augustine, San Augustine County (Palmer no. 9511), 
and Bryan, Brazos County, Texas (Palmer no. 10747). . 
QueERCcUS ALBA L.—There are three varieties of the eastern 
white oak. 
1. The tree with leaves deeply divided, sometimes nearly to the 
midrib, into narrow lobes lanceolate or obovate and often toothed 
at apex, and sessile or long-stalked fruit, the scales of the cup being 
often much thickened. This is the Q. alba of Linnaeus, his “Quer- 
cus foliis oblique pinnatifidis: sinubus angulisque obtusis,” as 
he quotes CaTEsBy’s description and figure which represents this 
form with deeply divided leaves. It is the Q. alba pinnatifida of 
Micuavux (Hist. Chénes Amér. pl. 3. fig. 1. 1801), who considered 
it the type, as did Micuavx fils; and it is this form, although it has 
been usually treated as a variety in recent years, which must be 
considered the type of the species. 
2. The tree with leaves less deeply divided, with broad rounded 
lobes and usually smaller generally sessile fruit. This form appears 
to have been first figured by Du Ror in 1772 in his Harbk. Baumz. 
pl. 5. fig. 1. It is the Q. alba of Asporr and Situ (Insects of 
Georgia, pl. 85) and of Emerson’s Trees of Massachusetts; and it is 
this form which later authors have usually considered to be the type 
of the white oak. This variety may be distinguished as
