RANUNCUEACEAE OF IOWA. H7 



Allamakee, Emmet, and Shelby counties. The State Uni- 

 versity herbarium has specimens from Delaware, Hardin, 

 Calhoun, and Lyon counties. We have seen a specimen 

 from Crawford county. Prof. Bessey reports the species 

 from Fayette and Floyd counties; Prof. Hitchcock from 

 Story county; and Prof. Pammel from Woodbury county. 

 This restricts the species in our state to the northern half, 

 reaching its southern limit on the western border.

Clematis virginiana L. Amoen. Acad., vol. 4, p. 

 275. 1759. Virgin's Bower. 



A rather long, trailing vine, with opposite trifoliolate 

 leaves, and small, white, polygamo-dioecious, cymose- 

 paniculate flowers. Sepals 4. Petals wanting. Stamens 

 many. Achenes many, in a globular head, with long, 

 persistent, plumose styles. 



The Virgin's Bower is rather common in low grounds in 

 thickets or along fenceways, flowering from July until 

 September. Our specimens are from Winneshiek, Alla- 

 makee, Fayette, Muscatine, Johnson, Appanoose, Decatur, 

 Ringgold, Page, Fremont, and Dickinson counties. We 

 have observed the species in Scott, Des Moines, and Union 

 counties. The State University herbarium has specimens 

 from Delaware, Jones, Lee, Story, Cerro Gordo, and Lyon 

 counties. Prof. Bessey reports the species from Floyd 

 county; Prof. Pammel from Woodbury county; and Mr. 

 Mills by letter from Henry county. This shows that the 

 distribution of this species is general throughout the state.
