Anemone virginiana L. 



it prefers a dry habitat, although the only place I ever saw it growing 

 in abundance was on a gravelly bench on the north side of Wall Lake in 

 Lagrange County, which was only a few feet above the water level. This 

 bench was made several years ago when the water level of the lake 

 receded. In this moist habitat the plants were common and vigorous, one 

 of the specimens having 7 fruiting heads.

5. Anemone virginiana L. Tall Anemone. Map 948. Infrequent to 

 frequent throughout the state. This is a woodland species and is rarely 

 found in the open along roads and railroads. It generally grows in dry 

 soil on wooded slopes and has a decided preference for slopes along 

 streams. 



The species varies considerably in the length of its stamens and in the 



size, shape, texture, and color of its sepals. Some of the variations have 



been given names but after a careful study of my 77 specimens from all 



parts of the state I have decided that the characters are too variable to be 



of taxonomic value.

1. Anemonella thalictroides (L.) Spach. (Syndesmon tlmlictroides 

 (L.) Hoffmg.) Map 949. Infrequent to very frequent in all parts of the 

 state except in the prairie areas and in very sandy areas. This is strictly 

 a woodland plant which is found generally in dry soil, usually on slopes 

 and banks along streams and ravines. 



This species is variable in many ways and some of the variations have 

 received names. Hill (Bot. Gaz. 10: 262. 1885.) wrote of finding speci- 

 mens near Hobart, Lake County, with "flowers greatly doubled, of 20-30 

 purplish petals, alternating in whorls."
