with rare articles : in both the calyx burfts on one fide, and 

 has three or four very fmall teeth at the end. In the Supple- 

 inentum PlantaYum this form of the calyx is particularly men- 

 tioned, and it appears, though rather obfeurely, in Gmelin's 

 figure, but not in that of Pallas, although very evident in 

 his fpecimen preferved in the Bankfian Herbarium. Radical 

 leaves are for the mofl part longer and flenderer than in our 

 figure and only three-nerved : Cauline ones grow by pairs, but 

 frequently face one way. The ftalks, at firft decumbent, rife 

 up, though flender and weak ; branches oppofite, lower ones 

 long. Flowers both-axillary and terminal on peduncles vary- 

 ing in length. Segments of corolla more obtufe than in 

 Gentian a Pneumonanthe^ and the whole plant much more 

 lax. 



Native of Siberia, where it is ufed in medicine as a mild 

 aromatic bitter. 



Introduced into this country by Mr. Loddiges, to whofe 

 fkill and indefatigable zeal our gardens are indebted for a 

 greater number of their prefent ornamental inhabitants than 

 is generally known. Is perfectly hardy. Flowers in }uly 

 and continues in bloffom a confiderable time. Can fcarcely 

 be piopagated but by feeds, having a tap-root, which feldom 

 . produces any offsets.
