1. Utricularia purpurea Walt. (Vesiculina purpurea (Walt.) Raf.) 

 Purple Bladder wort. Map 1883. Local and sometimes common. In 1930, 

 in a bayou of about 5-10 acres in Lake Cicott, Cass County, it was com- 

 mon in about 3-5 feet of water, associated with Utricularia macrorhiza, 

 Nuphar advena, and Nymphaea tuberosa. It has been reported also from 

 Marshall County. 



Maine to Fla. and La., near the coast; also in Mich., Ind. to Minn. 



2. Utricularia resupinata B. D. Greene. (Lecticula resupinata (B. D. 

 Greene) Barnhart.) Map 1884. Reported from Lake, Marshall, Noble, and 

 Whitley Counties. It is local and grows on wet, sandy or marl borders of 

 lakes or in shallow water up to 10 inches deep. 



N. B. to w. Ont. and Pa., southw. to S. C. and Fla. 



3. Utricularia cornuta Michx. (Stomoisia cornuta (Michx.) Raf.) 

 Horned Bladderwort. Map 1885. This is one of our rarest species. It 

 has been found only in St. Joseph, Elkhart, and Lake Counties. It was 

 formerly common on the wet, sandy borders of sloughs near Lake Michi- 

 gan in Lake County. 



Newf. to Minn., southw. to Fla. and Tex. 



4. Utricularia gibba L. Humped Bladderwort. Map 1886. This is a 

 small species usually found on the wet sandy or mucky borders of lakes 

 and sloughs. A few years after the highway was built around Bass Lake, 

 Starke County, I found this species and Utricularia resupinata by the 

 thousands in the bottom of the moist, sandy roadside ditch. It was no 

 doubt frequent throughout the lake area before it was drained, and rare 

 elsewhere. 



Maine to Mich., southw. to Fla. and Tex. 



5. Utricularia intermedia Hayne. Map 1888. This species has been re- 

 ported from Kosciusko and Marshall Counties by Clark, and from Lake
