1. Scirpus subterminalis Torr. Map. 365. My only specimens were 

 found in a colony on the muddy border of the south side of Long Lake, 

 Porter County, about a mile east of the Lake County line, where it was 

 associated with Scirpus validus. In walking the entire length of the lake 

 I noted only one colony. This was in very mucky soil from which the 

 water had receded just far enough to expose the soil.

2. Scirpus debilis Pursh. Map 366. This species has been found in a 

 few counties only in wet or mucky soil about sloughs in the dunes.
