The Flora of thf. Cayuga Lake I'.asin 183 



Forest Home Drive; island in Beebe Lake (D.) ; near Fall Creek, e. of Freeville 

 (D.) ; " Round Marsh and several places in the interior of Beaver Creek Swamp, 

 where it is manifestly native" (D.) ; McLean Bogs; South Cortland; thicket n. e. 

 of Mud Pond, Conquest. Escaped from cultivation at many of the above-named 

 stations.

 Its indigenous range in the East is now obscure. Found also in Eurasia. 



Plants from the above-named stations correspond mostly to H. americanus Nutt. 

 as treated by Bailey (Man. Cult. PI., p. 240. 1924), but this is doubtfully a distinct 

 species.
