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.

 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.
