IOWA ACADEMY OE SCIENCES. 
The flowers appear in May and June, and the acorns 
ripen in September and October. Within Iowa the species 
is widely distributed. The species ranges northward into 
Minnesota, southward into Missouri, eastward to Maine, 
but apparently not to the westward of Iowa. Our speci- 
mens are from Johnson, Appanoose, Decatur, Ringgold, 
Fremont, and Pottawattamie counties. We have observed 
the species in Allamakee, Dubuque, Jackson, Scott, and 
Taylor counties. The State University herbarium con- 
tains specimens from Delaware county. Professor Fink 
reports the species from Fayette county; Mr. Reppert, 
from Muscatine county; Professor Hitchcock, from Story 
and Blackhawk counties; Professor Macbride, from Hum- 
boldt county; and Mr. Mills, by letter, from Henry county.

Quercitron. This species very much resembles Quercus 
coccinea Wang.; the outer bark is dark brown, rougher, the 
inner bright orange; leaves pinnatifid or lobed to beyond 
the middle, brown-pubescent or stellate-pubescent when 
young, glabrous when mature, dull green above, pale 
green and usually pubescent on the veins beneath, leaf- 
lobes triangular-lanceolate or broad-oblong, usually 
coarsely toothed at the apex, lobes and teeth bristle- 
tipped; acorn ovoid, about twice the length of the cup, cup 
hemispheric or top-shaped, commonly short-stalked, scales 
more or less pubescent, the upper somewhat squarrose.
