12 Bigelow on the Medical Botany of Ohio. [Nov. 



Sp. 42. Robinia pseudacacta. Linn. 



Com. names — Common Locust, False Acacia, Black Locust- 

 Flowers white; fragrant; large tree. — June. 



Inner bark sweetish, like liquorice, emetic, cathartic and 

 pectoral, according to doses; root best. Blossoms laxative. — 

 (Rafinesque Med. Flor. Vol. II. p. 258.) 



Sp. 43. Baptisia leucantha. Torr. and Gr. 



Com. name — Tall White False Indigo. Flowers white. — 

 Pods 2' long. — July. 



Closely allied to B. Tinctoria, of which a tolerable good his- 

 tory is given by Rafinesque, (Med. Flor. Vol. I. p. 79,) and 

 Wood and Bache. It possesses the same properties and is 

 considered valuable by some physicians. 



Sp. 44. Cassia cham.ecrista. Linn. 



Com. names — Prairie Senna, Partridge Pea, Wild Senna. — 

 Stems spreading; 1° long; showy, bright yellow petals. — Aug. 



Riddell says that this is a better cathartic than the C. Mari- 

 landica, and most writers, that this last is better than the Egyp- 

 tian Senna of the shops. I have used C. Marilandica, but have 

 not been pleased with it. My ill-success with it however, may 

 have been caused by its not having been gathered and cured 

 in a proper manner, and at a proper season. I gathered in 

 Summer, when it was in blossom; but Rafinesque says it 

 should be collected in Autumn after the fruit has ripened. If 

 it is worthy, it should certainly supersede the foreign article. 



Sp. 45. Tephrosia virginiana. Pers. 



Com. names — Hoary Pea, Turkey Pea, Goat's Rue, Catgut, 

 Devil's Shoe Strings — 1° high; large, handsome blossoms, yel- 

 lowish-white, marked with red-purple. — June. 



Griffith, (Med. Bot., 248,) recommends giving it a fair trial, 

 from the fact that other species of the genus are known to 

 possess active qualities, especially of a purgative character. 



Order XVIII.— ROSACEA. (Rose Family.) 

 A well known order, possessing valuable astringent, tonic, 

 and anodyne properties. 



Sp. 46. Spiraea opulifolia. Linn. 

 Com. name — Nine Bark. Shrub 4° — 10° high. Flowers 

 white ; pods tinged with purple. — June. 



Sp. 47. S. Salicifoua. Linn. 

 Com. name — Willow-leaved Meadow Sweet. Shrub 2° — 

 5° high. Flowers white; tinged with purple. — July.
