Clematis simsii Sweet, Hort. Brit., vol. 1, p. 1. 



A rather high climbing vine, with opposite, pinnate 

 leaves, terminating in tendrils, and large purplish, solitary- 

 flowers. Leaflets 3-7, ovate, entire, lobed or trifoliolate, 

 thick, reticulated, more or less mucronate. Calyx cam- 

 panulate, pubescent, less than an inch in length; sepals 

 thin, tips recurved. Acheneswith filiform, persistent, silky 

 but not plumose styles. Clematis pitchcri T. & G., Fl. 

 N. A., vol. 1, p. 10, 1838. C/emat/s cordata Sims, Bot. 

 Mag. pi. 1816, 1816. Not Pursh, 1814. 



This species is frequent in thickets, flowering from June 

 until August. Our specimens are from Muscatine, John- 

 son, Appanoose, Decatur, Pottawattamie, and Shelby coun- 

 ties. We have observed the species in Union and Fremont 

 counties. The State University herbarium has specimens 

 from Louisa, Henry, Lee, and Story counties. Messrs. 

 Nagel and Haupt report the species from Scott county. 

 Our present information indicates that within our limits 

 this species is restricted to the southern portion of the 

 state. Britton and Brown give the range as southern In- 

 diana to Missouri and Texas which indicates a range south 

 of Iowa, a mistake however. A form with cream colored 

 flowers occurs at Moscow, Muscatine county.
