3. CIRCiEA. 



1. C. Liitetiana {common Enchanter's Nightshade), stem erect 

 pubescent, leaves ovato-cordate denticulate. Light/, p. 80. 

 E. B. I. 1056. 



Hab. Woods and coppices. H.June, July. 1/. 



Leaves delicate, on long footstalks, acute, scarcely cordate at the base ; 

 lipper ones nearly ovate. Racemes (as well as the stems) more or less- 

 branched, pubescent. Hott-ersw-hite or rose-coloured. Caly cine leaf- 

 lets reflexed. Petals obversely heart-shaped, patent, Germen hispid. 



2, C. alpiva [alpine Encha?iter's Nightshade), stem ascending 

 glabrous, leaves cordate toothed shining. Lightf. p. 80. 

 E. B. t. 1057. 



H.4B. Alpine woods and coppices, and by the side of the Highland 

 lochs frequent. Ft. June, July. 11 . 



Stems glabrous or nearly so, though they are represented, as well as 

 the leaves, as very pubescent in E. B. Leaves broadly cordate, gla- 

 brous, notched at the base, even in the upper ones, more decidedly 

 toothed and more shining than in C Lulet. : whole plant smaller. 

 Such are the principal marks I can discover that will serve for distin- 

 gui'ihing the two species. These differences however are retained in 

 cultivation, tit least in transplanted roots. Of the C.alpina I have 

 never .^jecn perfect seeds.
