Louisa county. Professor Macbride reports the species 
from Johnson county; Professor Bessey, from Des Moines 
county; and Messrs. Barnes, Reppert, and Miller, from 
Scott county. Thus it will be seen that there is a cres- 
cent distribution of this species in Iowa, the localities all 
being southeastern. The species ranges northward to Wis- 
consin, southward to Arkansas, eastward to Massachusetts 
and Delaware.

Quercus texana Buckley, Proc. Phila. Acad., 1860:444,, 
1860. Texan Red Oak. This oak is very similar to Quercus 
palustris DuRoi, becoming a large tree; bark reddish- 
brown, with broad ridges; leaves obovate in outline,, 
bright green above; paler and with tufts of wool in the axils 
beneath, deeply pinnatifid into 5-9 triangular or oblong 
lobes which are entire or coarsely few-toothed, the lobes 
and teeth bristle-tipped; acorn ovoid, 2-3 times the height 
of the deeply saucer-shaped cup; scales obtusish or acute,, 
appressed. 
The Texan red oak we have not seen. We include it on 
the authority of Professor Pammel, who states that it 
occurs at Webster City, Hamilton county. Britton and 
Brown refer the species to Iowa.
