Sp. 48. S. Tomentosa. Linn. 



Com. names — Hard Hack, Steeple Bush, Rosy Bush. Shrub 

 3° high. Flowers rose color. — July. 



Not well recognised in our books. Griffith, (Med. Bot. 281,) 

 states that the part recognised in the U. S. Pharmacopoeia, is 

 the least valuable; and S. Tomentosa, is the only one noticed. 

 They should be further and more closely investigated. 



Sp. 49. S. Lob ata. Murr. 



Com. name — Queen of the Prairie. Herbaceous, perennial. 

 Stem 4° — 8° high. Flowers deep peach blossom color; very 

 handsome. 



The blossoms, and probably the young seed pods, possess a 

 peculiar fragant and aromatic astringency, that will doubtless 

 render it valuable when we come toknowmore of its properties. 



Sp. 50. Agrimonia eupatoria. Linn. 



Com. names — Common Agrimony, Cockle Burr, Stick-wort. 

 Root sweet scented. — July, Sept. 



Mild astringent, tonic and corroborant. Useiul in coughs, 

 and bowel complaints, (Rafinesque Med. Flor. 1-34.) 



Sp. 51. Sanguisorba canadensis. Linn. 

 Com. name — Canada Burnett. A tall herb; flowers white, 

 sometimes purple. — August, Oct. 



Slightly astringent and tonic — (Riddell Syn. West. Flor. 17.) 



Sp. 52. Geum virginianum. Linn. 



Com. names — White Avens, Evan root, Avens, Chocolate 

 root, Cure-all, Throat-root. 



Sp. 53. Geum vernum. Torr. and Gr. Syn. Stylipus. Raf. 



Com. name — Western early Avens. Flowers small, yellow. 

 — April, June. 



These, as also all the others of the genus, are astringent, 

 styptic, tonic, febrifuge, and stomachic. Much neglected by 

 the profession, from no other cause that I know of, but that 

 they are so easily obtained. 



Sp. 54. PoTENTILLA CANADENSIS. Lind. 



Com. names — Cinque-foil, Five-finger. Very common. — 

 Flowers yellow. — April, October. 



Sp. 55. P. Norvegica. Linn. 



Com. name — Norway Cinque-foil. A coarse, homely, an- 

 nual or biennial weed. — July, Sept. 

 A very good mild astringent. 



Sp. 56. Comarumpalustre. Linn. Syn. PotentUla Palustris. Scop. <fec. 



Com. name — Marsh Cinque-foil. Stems 1° — 2° high.— June. 

 Another active and useful astringent.
