Fraxinus quadrangulata Michx 



6. Fraxinus quadrangulata Michx. BLUE Ash. Map 1614. Found spar- 

 ingly throughout the state, although we have no records from the north- 

 western counties. It is generally found on high ground and where its 

 distribution is limited, it is usually restricted to the high banks of streams. 



Ont. to Iowa, southw. to Tenn. and Ark. 



7. Fraxinus nigra L. Black Ash. Map 1615. Rather local but usually 

 of considerable abundance in its preferred habitat. Found in wet and 

 swampy woods throughout the lake area ; southward it becomes an infre- 

 quent tree of swampy places. There are no records for the unglaciated 

 area except in the White River Valley. The species is more frequent in 

 northern Indiana than our map indicates. 



Newf. to Lake Winnipeg, southw. to W. Va., Ind., and northwestern 

 Ark. 



6427. FORESTIERA Poir. 



1. Forestiera acuminata (Michx.) Poir. (Adelia acuminata Michx.) 

 Texas Adelia. Map 1616. Low borders of sloughs, swamps, and river 

 banks. It is usually associated with buttonbush. Very local. 



Sw. Ind. to Mo., southw. to Tex. 



245. LOGANIACEAE Dumort. Logania Family 

 6453. SPIGELIA L. 



1. Spigelia marilandica L. Pinkroot. Map 1617. Our only known 

 station for this plant is a post oak flat just south of Half Moon Pond about 

 10 miles southwest of Mt. Vernon, Posey County. It is frequent here over 

 several acres. The report for Marion County is doubtless an error. 



Ohio, s. Ind. to Mo., southw. to Fla. and Tex.
