The Flora of the Cayuga Lake Basin 361 



Lake marshes (D.) ; Ringwood (£>.!) ; Freeville (D.) ; McLean (D. !) ; Taughannock 

 Gorge; Paine Creek; Big Gully; and elsewhere. 



W. Que. to Ont. and Mich., southw. to Ga., Ala., and Tenn. ; rare or absent on the 

 Coastal Plain. 



The flowers vary in color from cerise to almost scarlet. 



A form with purple corollas and bracts, and somewhat intermediate between 

 M. didyma and M. fishllosa in texture, color, and pubescence of the foliage, is 

 M. fistulosa, var. rubra, of Gray, and is probably a hybrid of the two species 

 mentioned. A study of the material in several large herbaria tends to support this 

 view. In the Cayuga Lake Basin this form has been found : "on the wild bank 

 beyond the Fleming S. H." (D. !) ; by the roadside northw. from the mouth of Enfield 

 Glen; s. crest of upper Buttermilk Glen; lower end of Big Gully (K. M. W ., A. J. E., 

 & L. F. Randolph). 



2. M. clinopodia L. Balm. 



Damp thickets in ravines ; rare. July-Aug. 



Six Mile Creek, near Green Tree Falls (£>.!); base of hill n. of Lick Brook; 

 Trumansburg ravine (£>.). 



Ont. and N. Y. to 111., southw. to Ga. and Ky. A plant of the western slope of 

 the Allegheny Mts., and of the Ohio Valley. 



3. M. fistulosa L. Wild Bergamot. 



Dry gravelly river banks, shores, and hills, the lime preference not known; 

 frequent. July 20-Sept. 10. 



Dry hilltop fields, North Spencer; roadside n. e. of mouth of Enfield Glen; 

 Negundo Woods, and up the Inlet Valley to Newfield (D.) ; Renwick (D.) ; region 

 of Mud Creek, Freeville; Myers Point (D.) ; Taughannock (D.) ; Salmon Creek, 

 s. of Genoa; Paine Creek (D.l) ; Utt Point; Union Springs (D,). 



Me. to Minn, and Colo., southw. to Fla., La., and Tex. ; rare on the Coastal Plain. 



3a. M. fistulosa L., var. mollis (L.) Benth. (Var. mollis, in part, of Cayuga Fl. 

 M. mollis of Gray's Man., ed. 7.) 



Of same habitat as the typical form, and often growing with it; more frequent. 

 July 20-Sept. 10. 



Roadside thicket n. of mouth of Enfield Glen ; Buttermilk Glen ; hilltop s. e. of 

 Brookton ; s. w. corner of Cayuga Lake ; Fall Creek, above Forest Home ; near 

 Mud Creek, Freeville ; Salmon Creek, s. of Genoa. 



Range nearly the same as that of the typical form of the species. 



This can scarcely be considered a separate species, as it differs from the typical 

 form of M. fistulosa only in the absence of the longer type of hairs in the pubescence. 



4. M. punctata L. Horse Mint. 



Dry acid sandy fields and roadsides ; rare. Aug. 20-Sept. 15. 



Abundant along the Phelps-Junius town-line road s. w. of Junius ponds, 1920 

 (K. M. W., A. J. E., & L. F. Randolph), doubtfully native. 



N. Y. to Minn., southw. to Fla. and Tex., including the Coastal Plain ; adventive 

 also in N. E. 



15. Hedeoma Pers. 

 1. H. pulegioides (L.) Pers. American Pennyroyal. 



Dry sandy or stony soil in exposed places, apparently showing no lime preference ; 

 common. Aug. 



N. S. and Que. to N. Dak., southw. to Fla., Ala., Ark., and Nebr., including the 

 Coastal Plain. 



The European pennyroyal is Mentha Pulegium L.
