Shingle and the Willow oaks, producing thereby varieties that are 
recognizable and have in consequence been named. Quercus tlict- 
Solia is likewise known to be one of the parents of a hybrid form. 
The cross between nigra and tlictfolia, however, is not men- 
tioned, and as it isalso a recognizable form I wish to propose for 
it the name of Quercus Brittoni, after Dr. N. L. Britton, who 
was born on the island, and who, with Mr. Arthur Hollick, has 
done so much in making known its flora. 
Il—A single oak of much interest stands in a thick growth 
of trees in moist ground not far from the specimens of Quercus 
Srittoni mentioned above. It is sixteen inches in circumference 
several feet from its base, and once stood about twenty-five feet 
high, as proved by measurement, though in consequence of a de- 
cayed base the trunk is now partly prostrate. A considerable 
portion of the tree is still clothed in leaves, which are white-downy 
beneath, and it produces acorns, but neither the fruit nor the foli- 
age is distinguishable from that usually borne by the diminutive 
tlictfolia, which commonly has a trunk no larger round than one 
of the branches borne by this tree. 
Wood says of Quercus ilictfolia: “a shrub” three to four feet 
high; Eaton and Wright give two to eight feet, and Loudon, in 
his Encyclopedia of Trees and Shrubs, says: “This very remark- 
able little tree is generally found about three or four feet high ; 
but in favorable situations it is sometimes found to reach the 
height of eight or ten feet.” Lastly, in the recent edition of 
Gray’s Manual it is mentioned as dwarf and straggling, and eight 
is given as the maximum height. 
It will be seen from these facts that this tree has attained 
ver twice the size heretofore accorded the species, which cer- 
tainly makes it interesting and noteworthy. 
Buchloe dactyloides, Englm., not a Dicecious Grass. 
The common buffalo grass of the “ plains ” is well known to 
botanists. It begins to appear near the ninety-fourth meridian, 
and extends westward to the Rocky Mountains, northward into 
the British possessions, and southward to the sands of the 
Gulf coast, It is a grass of short stature, seldom more than six 
inches tall, though I have specimens collected in this State more
