The Quercitron is infrequent in Iowa, and occurs in 
upland woods. The species is readily distinguished in the 
woods, but not so readily from the herbarium specimens. 
The color of the outer and inner bark is the safest guide. 
The pubescence in the axils of the veins beneath varies, 
and is to be found in Quercus coccinea Wang. The squar- 
roseness of the scales intergrades. 
The Quercitron has been confused with the scarlet oak 
to such a degree by Iowa botanists that it is extremely 
difficult to give any definite information regarding its 
range in Iowa. The reports of the species from eastern 
Iowa seem the more credible. We have looked upon 
the reports from western Iowa with considerable suspicion. 
For many years the species has been recognized as 
occurring in Johnson county. Dr. White reported the 
species from Iowa, and was quoted by Professor Bessey. 
Professor Macbride reported the species from Dubuque and 
Humboldt counties; Messrs. Nagel and Haupt, from Scott 
county; Professor Pammel, from Hardin county; Profes- 
sor Fink, from Fayette county; Mr. Glow, from Adair 
county; Mr. Bigg, from Calhoun county; and Messrs. 
Barnes, Reppert, and Miller, from Scott and Muscatine 
counties.
