“supra pallidis, subtus subglaucis,”’ but as the leaves of Q. austrina are bright 
green on both surfaces, WALTER’s Q. sinuata was probably not that species. The 
description of the leaves would better apply to Q. Durandii Buckl., although 
the leaves of that. species are not ‘‘supra pallidis,”’ but, ‘‘subplanis”’ might be 
used to describe the very shallow cups. Q. Durandii, however, is not known to 
grow in Carolina or nearer Charleston than Albany, Georgia, which so far as I 
know is the eastern station for this oak, and it is hardly safe to take up WAL- 
TER’s name for Q. Durandii, especially as his specimen is not found in his 
herbarium in the British Museum. 
QUERCUS STELLATA Wang.—That the post oak should have 
developed many forms is not surprising, for it is distributed from 
southern Massachusetts to western Oklahoma and to western 
Texas, and is found on dry hillsides, sandy plains, and deep bottom 
lands often inundated for several weeks at a time. Except in size, 
the fruit of Q. stellata shows little variation, and the leaves, which 
vary greatly in shape and in the character of their pubescence, 
cannot be depended upon to separate the different forms. On 
what is considered the typical post oak the upper lateral lobes of the 
leaves are broad and truncate or slightly lobed at apex. On trees 
with leaves of this shape leaves are often found with the upper lobes 
narrowed and rounded at apex; and the clusters of fascicled hairs on 
the upper surface, which usually well distinguish through the season 
the northern or typical form of this tree, are often early deciduous 
or entirely wanting from other forms. On the northern tree the 
branchlets of the year are stout and thickly covered with pale 
tomentum, and on some of the southern forms the branches are more 
slender and glabrous or only slightly pubescent when they. first 
appear, and in the branchlets is the best character I have found by 
which to group the different forms. The pubescence on the lower 
surface of the leaves of forms with glabrous branchlets is usually 
loose or floccose and sometimes deciduous. The close pubescence 
of fascicled hairs, however, found on the lower surface of the leaves 
of the typical post oak, is found also on some of the forms with the 
glabrous branchlets. Forms of the post oak with scaly bark, like 
that of the white oak, have always with one exception, so far as I 
have been able to observe, glabrous branchlets and occur only in 
the south, and the forms on which all or nearly all of the leaves have 
rounded lobes are also southern,
