1918] SARGENT—QUERCUS 459 
This plant has every appearance of being a Q. stellata-virginiana cross. 
The thickened leaves with thickened revolute margins and the conspicuous 
reticulate veinlets point to var. geminata of Q. virginiana as one of the parents; 
the narrow and often rounded lobes of many of the leaves, the character of 
the pubescence on their lower surface, and the slender reddish slightly pubes- 
cent branchlets and globose nearly glabrous buds point to var. Margaretta of 
Q. stellata as the other parent. 
A small tree 4-5 cm. tall found by E. J. Palmer at Fort Chadbourn, 
Coke County, Texas, July 9, 1917 (no. 1 2463), i is probably a hybrid between the 
typical Q. virginiana and one of the dwarf forms of Q. stellata, but without 
fruit it is not desirable to describe it. 
In the hope of drawing attention to them, names are proposed 
for the following hybrid oaks, although the material available is 
not sufficient to make their description possible: 
Quercus Lowellii, n. hyb. (Q. borealis Xilicifolia). 
Seabury, York County, Maine, Percival Lowell, September 8, 1914 (without 
ruit). 
Quercus oviedoensis, n. hyb. (Q. cinerea X myriifolia). 
Oviedo, Orange County, Florida, T. G. Harbison, May 29, 1917 (nos. 10, 
20, type). A small tree with leaves intermediate in shape between those of its 
supposed parent. 
Quercus Cocksii, n. hyb. (Q. rhombica Xvelutina). 
Pineville, Rapides Parish, Louisiana, R. S. Cocks, April 18, 1917 (no. 4702, 
type). The leaves of this tree generally resemble in shape those of Q. rhombica, 
but occasionally are slightly lobed and are rusty and thickly covered below 
with pubescence.
