96 TETRANDRIA. MONOGYNIA. 



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

 Flowers by pairs upon the same gtM-m, supe- 

 rior — Calix 4-t()(»(hed. Corolla fiiiinel form, 

 tube eylimlric; limb 4 parted, spreading viil us 

 on the inner side. Stamina 4, scarcely exserted.

 germs, didymous, 4-seedpd. 



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 gi nus JVIitchella appears to be somewhai allied to 

 ^iegiphila or JVuxia, and also to Symphoricarpos. 



139. LINN^A. Gronovius. L. 



Calix double: that of the fruit Sleaved, of the 

 flower 5-parted, superior. Corolla turbinate, 

 subcanipanulate, 5-lobed. Stamina somewhat 

 di'lynamous. Stigma globose. Berry sniall> 

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



Herbaceous, creeping, and semperrirent; leaves oppo- 

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

 fruit crowned by the permanent calix. 



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

 Gronovius to the name of Lmnseus, who discovered it in 

 the wilds of Lf.pland: 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 Susquehannali, to the arctic cir- 

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

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

 the cities canadensis, A. nigra, and .i. bahamea, accom- 

 panied by the THoitalisy Polygalu paitcifolia, Jllitchella, 

 and Gaultliena. Unchanged by the vicissitudes of cli- 

 mate, it always apparently presents the san.e character, 

 whether grow. ng in the fortsis of A.merica 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, jud.aing from the mere form of 

 the corolla, referred it to Ca?npa7iula, and called it C ser- 

 pylUfolia.
