Excluded Species 1077 



species will sooner or later become established in the state if it has not 

 already done so. Britton and Brown in Illus. Flora, ed. 2, say: "Large- 

 flowered races of the preceding species (Oenothera biennis) have been mis- 

 taken for it." Therefore our reports may not be authentic. 



468. Oenothera fruticosa L. {Oenothera linearis Michx. of Gray, 

 Man., ed. 7 and Kneiffia linearis (Michx.) Spach of Britton and Brown, 

 Illus. Flora, ed. 2.) Reports of this species for Indiana no doubt should be 

 referred to some other species and I am referring the reports from Jasper 

 County by Welch and from Lake County by Pepoon and by Peattie to 

 Oenothera tetragona var. longistipata. 



469. Oenothera OakesiAna Robbins. Reported from Putnam County 

 by Cook, who found it in a quarry in Greencastle. In this habitat it should 

 be regarded as a waif. 



Sandy fields, e. Mass. to Long Island. 



470. Oenothera albicaulis Pursh. Reported from Hamilton County 

 by Wilson, who found it along a railroad. He reported it also from Tippe- 

 canoe County where he collected it in a meadow (probably a hayfield) 

 east of Lafayette. There are no specimens nor any evidence that it has 

 become established. 



Dry plains and prairies, Sask. to w. Minn., westw. and southw. 



471. Oenothera triloba var. parviflora Wats. This variety was reported 

 in Coulter's Catalogue for Blatchley as found in Monroe County. 



Munz (American Jour. Bot. 17: 360. 1930) now refers this variety to 

 the species which see on page 707. 



472. Circaea canadensis Hill. (Rhodora 19: 87. 1917.) (Circaea 

 intermedia Ehrh. of Gray, Man., ed. 7 and Britton and Brown, Illus. Flora, 

 ed. 2.) Reported from Lake and Porter Counties by Pepoon. Since he does 

 not report Circaea alpina L. which is known to occur there, and since the 

 range of this species is far to the east of Indiana, I believe that Pepoon 

 confused the species. Buhl (Amer. Midland Nat. 16: 252. 1935) says 

 there are no confirming specimens. 



E. Que. and N. S. to w. Mass and N. Y. ; found also in Eu. 



473. Myriophyllum humile (Raf.) Morong. This species was reported 

 from the area of Delaware, Jay, Randolph, and Wayne Counties by 

 Phinney. There is no specimen. 



Coastal Plain from Maine to Md. ; also reported in the interior from Ind., 

 111. to Tenn. 



474. Myriophyllum humile var. capillaceum (Torr.) Fern. Reported 

 from the Lower Wabash Valley by Schneck who says "in ponds, not rare." 

 There are no specimens. 



475. Myriophyllum verticillatum L. All of our reports for this 

 species were made before the last editions of our manuals were published. 

 Our latest manuals regard this species as Eurasian and refer the American 

 plants to var. pectinatum Wallr.
