RANUNCULACEAE OF IOWA. 107 



leaves slender-petioled or 3-cleft; involucre far below the 

 flower; sepals 6-20, linear, purplish varying to whitish, head 

 of fruit oblong. 



This species blooms in April and May and within our 

 limits it is of infrequent occurrence though often abundant 

 over small areas. Our specimens are from Muscatine county 

 contributed by Mr. Reppert who sends the following note: 

 "Sandy soil, Muscatine Island, and along Cedar river. 

 Flowers vary from white to bluish-purple . ' ' The State 

 University herbarium has specimens from Hancock and 

 Hardin counties. Dr. C. C. Parry reported the species 

 from Scott county which report is confirmed by Messrs. 

 Barnes, Reppert and Miller; and Prof. Bessey from Story 

 county which report is confirmed by Prof. Hitchcock. This 

 seems to confine the species within our limits to the north- 

 ern half of the state. The species ranges from Illinois to 

 Wisconsin and Nebraska, south to Georgia and Texas. Dr. 

 Parry in his catalogue has the following interesting note: 

 "Anemone caroliniana Walt., May 3d. Mississippi river 

 bank, Davenport and Rock Island. The geographical range 

 of this interesting species is deserving of notice. First 

 known as a native of the Carolinas, it is again met with in 

 Louisiana, Texas, and Arkansas, thence finding its way to 

 the Missouri and Platte rivers; the locality just specified, 

 probably determining its northeastern limits. It here grows 

 always associated with Draba caroliniana and Androsace 

 occidentalism a significant relationship, connecting as it 

 were the two extremes, Carolina and Nebraska."
