III. A Determination of Three British Species of Juncus, with 

 jointed Leaves. Bi/ the Rev. Hugh Davies, F.L.S. 



Read November 1, 1808. 



In the course of a morning's walk having been fortunate in an 

 opportunity of examining the knottj-leaved division of the ge-

 I am induced to request leave to lay before the Linnean Society 

 the result of my observations. 



Here then I must premise, that the want of an opportunity of 

 examining them in a proper state, and comparing them together, 

 I take to have been the cause that what seem to me to be di- 

 stinct species have been treated as varieties only, by men of 

 eminence in the science of botany. 



In consequence of the attention which I bestowed on them, I 

 anrmuch inclined to suppose that I can determine into three 

 very distinct species, what have been deemed two varieties only 

 of the species J. articulatus, Linn. Sp. PL, Sm. Fl. Brit., and 

 Leers FL Ilerhorn.; but are considered as two species, indeed, 

 by Dr. Sibthorp, viz. compressus and nemorosiis ; and two species, 

 likewise, by Mr. Rclhan, viz. compressus and articulatus. 



My <Arfe species I shall at present distinguish as first, se-

In the FfRST the branches of the panicle are strong, erect, 

 fewer, and less diffuse than in the other two ; the capsule is 

 large, of a deep reddish brown colour, and finely glossed ; of
