other plants, especially Dianthera americana, which is now clogging some 

 of our smaller streams. 



Pa. to Minn., southw. to Fla. and La. 



2. Hibiscus Moscheutos L. Common Rosemallow. Map 1398. Local 

 in the lake area of the state on the borders of streams and in roadside 

 ditches, millraces, and drained ponds. This species prefers a habitat with 

 more organic matter than the preceding species. Usually the colonies are 

 small but once I saw in a drained pond in Wabash County three acres of a 

 complete stand of this species. 



It has been reported also from Clark, Jefferson, Knox, and Posey Coun- 

 ties. All of these reports, how r ever, were made before our manuals sepa- 

 rated Hibiscus palustris from this species and doubtless all of these re- 

 ports should be referred to Hibiscus palustris. 



Along the Atlantic coast from Mass. to Fla. ; inland from Ont. and Mich, 

 to Mo. 



3. Hibiscus palustris L. (Hibiscus oculiroseus Britt. and Hibiscus 

 palustris L. f. oculiroseus (Britt.) Fern.) Map 1399. In ditches and ponds 

 in the southwestern part of the state. It is local but common where it is 

 found. The largest colony I ever saw was in hard, clay soil in a button- 

 bush pond of about 3 acres in a low, flat pin oak woods about 10 

 miles southwest of Mt. Vernon. I think all of the reports for Hibiscus 

 Moscheutos from southern Indiana should be referred to this species. I 

 saw it from a train window in a ditch in Jennings County. 



Along the Atlantic coast and up the Mississippi Valley to s. Ind. 



4. Hibiscus lasiocarpos Cav. Hairy-fruited Rosemallow. Map 1400. 

 I have found this species only on the muddy borders of ponds in the 

 southwestern part of Knox County, and in the southern part of Gibson 

 County. It has been reported from Daviess, Hamilton, and Vigo Counties. 

 It is probable that these reports should all be referred to the preceding
