 iparqanium chlorocarpum 



/ar. acaule (Beeby)Fern. 



occurs on the low borders of lakes, streams, and sloughs and in ponds 

 and springy places. 



N. S., Maine, Que. to B. C, southw. to Fla., Mo., Utah, and Calif. 



2. Sparganium androcladum (Engelm.) Morong. {Sparganium lucidum 

 Fern. & Eames.) Map 72. My only specimen is from a slough about 4 

 miles northwest of Grayville, Sullivan County. A specimen reported from 

 St. Joseph County should now be referred to Sparganium chlorocarpum. 

 The species of this genus are not well known, hence their distribution is 

 not, as yet, understood. 



Newf. to Man., southw. to Fla. and westw. 



3. Sparganium americanum Nutt. (Including var. androcladum Fern. 

 & Eames of Gray, Man., ed. 7.) Map 73. Infrequent in the lake area and 

 probably very local south of it. All of my specimens are from ditches, 

 sloughs, and outlets of lakes. 



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



4. Sparganium chlorocarpum Rydb. {Sparganium diversifolium of au- 

 thors.) Map 74. All of the specimens, with one exception, and reports are 

 restricted to the lake area where it is infrequent. It is found in habitats 

 similar to those of the preceding species. 



Newf. to Iowa, southw. to N. J., N. Y., and Ind. 



4a. Sparganium chlorocarpum var. acaule (Beeby) Fern. {Sparganium 

 diversifolium var. acaule (Beeby) Fern. & Eames and Sparganium acaule 

 (Beeby) Rydb.) Map 75. All of my specimens are from the lake area 

 except one which was found in Hancock County in a springy place along 

 a creek. It is infrequent but probably more common in the state than the 

 species. The habitat is that of the other species of the genus. 



Newf. to N. Dak., southw. to Va. and W. Va.
