Excluded Species 1023 



22. Pinus rigida Mill. Pitch Pine. Reported from Clark County, but 

 there is no verifying evidence that it was a native of the state. 



Maine to Ont, southw. to Va. and e. Ohio and in the mts. to Ga. and 

 Tenn. 



23. Abies BalsAmea (L.) Mill. Balsam Fir. Reported from Porter 

 County (Proc. Indiana Acad. Sci. 1900: 141. 1901). The report was an 

 error in quoting from Cowle's paper on the dunes of Lake Michigan. Not 

 found south of Michigan. 



24. Chamaecyparis thyoides (L.) BSP. Southern White Cedar. 

 See Deam's "Trees of Indiana," ed. 2, p. 306. 1932, for details of reports. 

 The range of the species is east of the Allegheny Mountains and no doubt it 

 never was a native of Indiana. 



25. Juniperus communis L. A small tree of pyramidal habit up to 35 

 feet high occurs in certain parts of North America and Eurasia. The up- 

 right form of the juniper does not occur in Indiana and all reports for it 

 should be referred to Juniperus communis var. depressa Pursh. 



26. Sparganium angustifolium Michx. (Sparganium simplex Fern. & 

 Eames as to plant, not Huds.) Reported by Buhl (Amer. Midland Nat. 16: 

 248. 1935) as found in the Indiana Dunes. He cites a specimen in the 

 herbarium of the University of Illinois and one in the herbarium of the 

 University of Notre Dame. I have seen both specimens and I refer them 

 to other species. Fassett writes me that there are three of Umbach's 

 specimens in the herbarium of the University of Wisconsin labeled Spar- 

 ganium simplex Huds. and they should be referred to Sparganium ameri- 

 canum and Sparganium chlorocarpum var. acaule. 



Newf., Que. to Alaska, southw. to Conn., N. Y., uplands of n. N. J. and 

 Pa., Mich., n. Wis., Colo., and Calif. 



27. Sparganium minimum Fries. This species was reported fifty years 

 ago from Lake County by Babcock and by Hill. The recent reports, I 

 believe, are based upon these old reports. Nieuwland reported it from St. 

 Joseph County, but the specimen proves to be Sparganium chlorocarpum 

 var. acaule. The range of this species seems to be north of Indiana. 



Newf., Que., Man., and Alaska, southw. to Conn., cent, and w. N. Y., 

 uplands of n. N. J. and Pa., Mich., n. Wis., Utah, and Oreg. ; Eurasia. 



28. Potamogeton dimorphus Raf. This species was reported from Vigo 

 County by Blatchley. Since I have not seen the Blatchley specimen, it 

 can not be properly referred, and it is best to omit this report. 



29. Potamogeton filiformis Pers. This species has been reported 

 from Lake and Marshall Counties. Since this is a northern species, and 

 there are no specimens from Indiana, it is excluded. 



Newf. to Alaska, southw. to Maine, Pa., and Colo. 



30. Potamogeton perfoliatus L. There are early reports from Kos- 

 ciusko, Lake, and Marshall Counties. As now understood, this species
