242 MINNESOTA BOTANICAL STUDIES. 



nesota specimens in the University Herbarium. They have 

 previously been confused with the two Minnesota species of 

 Zizia. 



Thaspium barbinode (Michx.) Nutt. Gen. PI. i : 196. 1818. 

 Hairy-jointed meadow-parsnip. 



Infrequent south. 



Herb.: Ballard 971, Nicollet county; Sheldon 791, 989, 

 Sleepy Eye, 1180, New Ulm ; Holzinger, Winona. 



Conioselinum chinense (L.) B.S.P. Prel. Cat. N. Y. 22. 1888. 

 Hemlock parsley. 

 Selinum canadense Michx. Fl. Bor. Am. 1 : 165. 1803. 

 Reported by Upham as occurring along the upper Mississippi 

 river. There are no authentic collections known from Minne- 

 sota. Its range apparently does not extend so far west as this 

 state. 



Angelica villosa (Walt.) B.S.P. Prel. Cat. N. Y. 22. 1888. 

 Pubescent angelica. 

 Archangelica hirsuta T. & G. Fl. 1 : 622. 1840. 

 Reported by Upham as collected in Wabasha and Anoka 

 counties. These collections were probably incorrectly deter- 

 mined as Minnesota is rather too far north to be included in 

 the natural range of this species. 



Angelica atropurpurea L. Sp. PI. 1: 251. 1753. Great an- 

 gelica. 

 Archangelica atropurpurea Hoff. Umbel. 162. 1814. 

 In moist soil, east. 

 Herb. : Several collections from eastern Minnesota. 



Cymopterus acaulis (Pursh) Rydb. Bot. Surv. Neb. 3: 38. 

 1894. Plains cymopterus. 

 Cymopterus glomeratus DC. Prodr. 4 : 204. 1830. 

 Reported by Upham as collected by Lapham in the Red 

 river valley. Its occurrence, however, is rather doubtful. 

 Polytaenia nuttalli DC. Coll. Mem. 5: 54. 1829. 

 In dry soil, southeast. 



Herb. : Hvoslef, Lanesboro ; Sandberg, Vasa. 

 Oxypolis rigidior (L.) Raf. in Seringe, Bull. Bot. 218. 1830. 

 Cowbane. 

 Archemora rigida DC. Prodr. 4 : 188. 1830.
