Some new Hybrid Oaks from the Southern States. 
By JouHNn K. SMALL. 
(PLATES 232-235.) 
The following is a record of some observations on several 
interesting forms of Quercus growing in North Carolina and 
Georgia, together with a striking hybrid existing in two well- 
marked forms, found in Lake county, Florida, by Mr. Geo. V. 
Nash, during his collecting trip of last season. : 
Quercus PHELLOS X Q. DIGITATA. 
A large and stout tree with rough scaly bark, reaching a 
height of from twenty to thirty-five meters, and. having a trunk | 
diameter ranging from six to nine decimeters. Trunk forking 
several feet from the ground, the divisions thence branching, the 
branches rather erect and the branchlets straggling ; leaves oblong, 
obovate or oblanceolate, 5-20 cm. long, 2-10 cm. broad, mostly 
entire and undulate or somewhat crisped, or more or iess twO-  ~ 
_ lobed or three-lobed near the apex, acute or obtuse at the apex, 
acute, obtuse or subcordate at the base, the upper surface dark- 
green and glabrous, the lower brown and more or less tomentose 
with reddish brown, stellate hairs, especially about the midrib and 
principal nerves ; mature fruit not seen. (Plate 232.) 
Hills west of the Falls of the Yadkin River, North Carolina. 
In 1892 I found a small grove of peculiar looking oak trees in 
a very shallow depression in the foot-hills of the Falls Mountains, 
just west of the Falls of the Yadkin River, in Stanley county, 
North Carolina. Specimens were collected, but there was not 
time for a thorough investigation of the case. The specimens 
suggested a form of Q. Rudkini(Q. Phellos * Q. nigra), and some 
were distributed under that name. Each succeeding year I have > 
observed the trees and their surroundings, and am now confident 
that the parents are not those of QO. Rudkini, but Q. Phellos and 
Q. digitata, the two prevailing species of the immediate region. 
Q. mgra, one of the undoubted parents of Q. Rudkini, was not 
observed within several miles. The form of Q. digitata, which iS 
apparently one of the parents of the hybrid under considera- 
tion, is not that with long, falcate leaf-lobes, but one common 
through the pine woods in the middle country of the Southern — 
States. Its leaf is not as deeply lobed and has a more cuneate
