The Flora of the Cayuga Lake Basin 401 



8. S. arguta Ait. 



Dry stony or rocky noncalcareous sandstone crests and hillsides, or in sandy woods ; 

 frequent. Aug.-Sept. 



Frequent in the chestnut soils of the higher hills of the basin, on the ravine 

 crests, along the shores of Cayuga Lake, and in the sandy country n. of the lake; 

 rare in- the McLean region (found near Mud Pond, McLean Bogs), and on the 

 clays and richer soils of the basin. Dudley mentions the species as inhabiting 

 sphagnum swamps, but it is not now known in such locations. .From the context, 

 it seems that Dudley's plants may have been forms of S. patula Muhl., and an old 

 specimen from "Malloryville Marsh" in the C. U. Herbarium, labeled S. arguta, is 

 6". patula. 



W. Me. to Ont, southw. to N. C. and Tenn., mostly in the mts. ; infrequent or rare 

 on the Coastal Plain. 



9. S. patula Muhl. 



Marl springs and meadows ; frequent. Sept. 



Larch Meadow ; Coy Glen ; Fall Creek, toward Varna ; e. of Freeville station ; 

 Mud Creek, Freeville ; McLean Bogs ; and elsewhere. 



W. Me. to Minn., southw. to Ga., Mo., and Tex. ; rare or absent on the Coastal 

 Plain. 



10. S. nemoralis Ait. 



Dry gravelly or sandy sterile fields, mostly in noncalcareous soils; common. 

 Aug. 20-Sept. 



Generally distributed throughout the basin, but most abundant in the chestnut soils 

 of the higher hills and along the shores of Cayuga Lake. 



P. E. I. to Sask., southw. to Fla., Tex., and Ariz. ; common along the coast. 



11. S. rugosa Mill. 



Dry fields and hedgerows, in gravelly soils ; common. Aug. 20-Sept. 



Abundant in the more sterile soils of the hills of the basin, as well as in the 

 more calcareous gravels of the McLean region, and even in the alluvium ; less 

 abundant, or rare, in the clays. 



Newf. to w. Ont., southw. to Fla. and Tex., including the Coastal Plain. 



11a. S. rugosa Mill., var. sphagnophila Graves. 



Boggy meadows; rare. Aug. 1-Sept. or rarely Oct. 



Moor of Lowery Ponds (F. P. Metcalf) ; Westbury Prairie (F. P. Meftalf & 

 A. H. Wright). In both these localities the plants grow in marly and sedgy 

 meadows. 



E. Mass. to Conn, and N. Y. 



12. S. ulmifolia Muhl. 



Dry rocky or stony banks, where the soils are not too acid and where there is 

 some admixture of clay; scarce. Aug. 15-Sept.

 abund. north of Myers Point" (£>.) ; s. of Willets station (D.) ; Big Gully (D.). 



N. S. and s. Me. to Minn., southw. to Ga., Mo., and Tex.; infrequent on the Coastal 

 Plain.

Fields and thickets, on low or at least poorly drained soils of very diverse types; 

 common. July 15-Sept.; early-flowering.
