 518. HALBERD-LEAVED ROSE-MALLOW 



HIBISCUS MILITARIS Cav. 



A few clumps down toward the mouth of the Outlet, not far 

 from the Tippecanoe River ; not found in the immediate vicinity of 

 the lake ; abundant along the Kankakee River. 



Although large insects, such as bumblebees, frequently visit the 

 flowers of this plant, probably for pollen, the nectaries are hidden 

 in the little tent formed about the base of the column which bears 

 the stamens, the only entrance to this tent being the five narrow 

 clefts between the lobes, of the corolla. This tent is usually in- 

 habited by a large number of minute beetles which are able to enter 

 the clefts. 



519. BLADDER KETMIA 



* 



HIBISCUS TRIONUM L. 



A few plants found along the north shore of the lake, near 

 Morris's boathouse. This low herb with its conspicuous creamy 

 black-eyed blossoms was a favorite in old fashioned gardens. It 

 has escaped, and in many parts of the state is becoming one of the 

 most pestiferous weeds. A well developed plant bears an enormous 

 number of seeds. These have great germinating power and will 

 spring up in cultivated ground almost at any time during the sum- 

 mer even after the cultivation for the year is over and rapidly pro- 

 duce seed. The seeds are easily distributed through hauling hay, 

 manure, etc.

HYPERICUM PUNCTATUM Lam. 



A few plants found along the lake shore south of Green's. 

 Rather common throughout the state in moist soil.
