Flora of the . iltegany State Park Region 107 



Viola palmata L. Palmate-leaved Blue Violet 



In sterile or acid (gravelly, stony or sandy soil of 

 the slopes and bluffs along the east side of the Alle- 

 gheny valley and on the conglomerate soils of the 

 higher ridgeSj in thin woods and thickets. Frequent. 

 Practically no specimens were seen with the typical 

 palmately-lobed leaves and rather soft pubescence 

 characteristic of this species in the Hudson valley. 

 Plants approaching the typical form were found on 

 Seneca mountain and on Butler run. Most of the 

 plants have the mature leaves of the "dilatata" or 

 "triloba" type, many of them unlobed or nearly so. 

 Numerous gradations occur to plants which are quite 

 glabrous (slopes of Elko mountain, Seneca mountain, 

 summit on Stony run trail), or with a minute white 

 puberulence on the petioles. On Huckleberry hill 

 occurs a form with almost truncate, triangular leaf- 

 blades, entirely glabrous even to the petioles, and 

 which would scarcely be connected with V . palmata 

 if occasional plants did not possess lobed leaves and 

 varying degrees of pubescence connecting with the 

 "dilatata" form. This smooth triangular-leaved 

 form on Huckleberry hill possesses a striking simi- 

 larity in leaf form to the coastal Viola emarginata. 



Viola sororia Willd. Meadow Blue Violet 



In moist, open woodlands, fields and alluvial bot- 

 tomlands. Infrequent and for the most part lacking 

 the characteristic soft pubescence of this species. 



Viola rotundifolia Michx. Stemless Yellow Violet 



In moist, fertile humus of damp woodlands and 

 forests throughout the park area. Common and con- 

 spicuous on the forest floor by its dark green orbicu- 

 lar or ovate leaves, Adiich in late summer are pressed 

 rather flat to the leafv litter.
