96 TETRANDRIA. MONOGYNIA. 



138. MITCHELLA. L. (Partridge-berry.) 

 Flowers by pairs upon the same germ, supe- 

 rior. — Calix 4-tootbed. Corolla fi^niiel form, 

 tube eyiiiidric; limb 4 parted, spreading vili--us 

 on tlie inner side. Stamina 4, scarcely exserted. 

 Stigma 4-cleft. Berry^ by the union of the 2 

 germs, didymous, 4-seeded. 



An herbaceous repent evergreen; flowers by pairs ter- 

 minal or axillary, berry scarlet, hibernal, edible, but in- 

 sipid. 



Species. 1. M. repens. The only species known; 

 extending in the shade of forests from Canada to Georgia. 

 The genus JHiichcUa appears to be somewhat allied to 

 JiegipUla or JWixia, and also to Symphoricarpos. 



139. LINN^A. Gronovius, L. 



Calix double: that of the fruit 2- leaved, of the 

 flower 5-partcd, superior. Corolla turbinate, 

 subcampanulate, 5-lobed. Stamina somewhat 

 didynamous. Stigma globose. Berry small, 

 ovate, diy, 3-celled, cells 2-seeded. 



Herbaceous, creeping, and semperrirent; leaves oppo- 

 site; surculi erect, the upper part naked and 2-flowered» 

 fruii crowned by the permanent calix. 



Species. 1. L. borealis. A small plant dedicated by 

 Gronovius to the name of Linnaeus, who discovered it in 

 the wilds of Liipland; it was afterwards found in Sweden, 

 in Germany, and in Scotland, where it had been overlook- 

 ed or neglected, and it is now also met with in all the 

 northern regions of the American continent, from the 

 mountainous banks of the Susquehannah, to the arctic cir- 

 cle: (abundant in the shady pine forests of Lake Huron.) 

 In America, the Linncea is confined to the dark forests of 

 the Abies canadensis^ A. nigra, and A. balsamea, accom- 

 panied by the Tnentalis, Polygala paticifoUuy JMitchellaf 

 and Gatilthena. Unchanged by the vicissitudes of cli- - 

 mate, it always apparently presents the same character, 

 whether growing in the forests of America or of Europe, 

 and in every system it stands alone, without distinct af- 

 finity to any other genus. Bauhin, indeed, after the man- 

 ner of the older botanists, judj^ing from the mere form of 

 the corolla, referred it to Campanula, and called it C. ser- 

 pyllifolia.
