The Flora of the Cayuga Lake Basin 215 



2a. T. polygamum Muhl., var. hebecarpum Fernald. 

 In situations similar to the preceding ; scarce. 

 Renwick ; Taughannock Point. 

 Newf. to Ont., southw. to N. H. and N. Y. 



3. T. revolutum DC. (T. purpurascens of Cayuga Fl.?) 



Sandy banks and open sandy woods; rare. June 10-30. 



Scrubby bank and near-by woods along road about % mile s. w. of Pout Pond, 

 growing with Monarda punctata, 1919 (K.' M. W ., A. J. E., & L. F. Randolph) ; 

 one plant in field at Esty's, 1922; "scarce, in Fall Cr. and elsewhere" (D.). Not 

 seen since at the last-named station, and the record is probably an error as this 

 species would not be expected in the locality cited. 



Mass* to Ont., southw. to S. C, Tenn., and Ind., including the Coastal Plain. 



10. Anemonella Spach 

 1. A. thalictroides (L.) Spach. Rue Anemone. 



Dry open woodlands and banks, in noncalcareous gravel, clay-gravel, or stony soil ; 

 common. Apr.-May 30. 



Common about the ravines and on the slopes of Cayuga Lake, occasional on the 

 higher hills, and rare or absent in the McLean region. 



S. N. H. and e. Mass. to Ont. and Minn., southw. to Fla., Tenn., and Kans. ; less 

 common on the Coastal Plain. 



Abnormal forms, with flowers double or wholly green, occur occasionally. 



11. Anemone (Tourn.) L. 



«. Achenes densely woolly ; plants tall, with petioled cauline leaves. 



b. Divisions of the cauline leaves 3-5 cm. long, cleft into rather narrow segments ; 

 heads of fruit cylindrical, very woolly, only the tips of the styles showing. 



1. A. cylindrica 

 b. Divisions of the cauline leaves 6-10 cm. long, much less finely cleft; heads of 

 fruit ovoid or oval, less woolly, the outlines of the achenes showing. 



2. A. virginiana 

 a. Achenes not woolly. 



b. Plants tall, 25-60 cm. high, several-flowered ; cauline leaves sessile ; achenes flat, 

 suborbicular, wing-margined, with straight or curved beaks. 



3. A. canadensis 

 b. Plants low, 8-20 cm. high, one-flowered ; cauline leaves slender-petioled ; achenes 



subterete, oblong, with hooked beaks. 4. A. quinquc folia 



1. A. cylindrica Gray. 



Dry open woods and banks, in sandy soils ; rare. June. 



Sandy crest of Salmon Creek ravine, e. of Five Corners ; roadside, Sherwood to 

 Auburn, 1880 (Miss I. Howland, D.) ; near Lowery Ponds and near Vandemark 

 Pond. 



W. Me. and e. Mass. to Sask., southw. to n. N. J., Pa., 111., Mo., Kans., N. Mex., 

 and Ariz. 



In sandy acid soils in the Cayuga Lake Basin, but apparently rare on the Coastal 

 Plain. Taylor (Fl. Vic. N. Y.) says, "most common on limestone." 



[A. riparia Fernald. 



Fernald cites this species from Tompkins Co. (see Rhodora 19:139. 1917), but 

 the authors have been unable to detect it here.]
