T. V. 



A 



Of the foliated Mops. 



S the plants of this kind are very numerous, I have been obliged to divide 



them into claues j and to range thofe that feem to anfwer in the generaf diipo- 



fitioo of their fructifications, together under the fame generic appellations/ 



I p . In this manner I have placed all thofe that bear oblong feed-venets on long and 

 llender foot-ftalks ; (whether they rife from the top, or inferior parts of either branch, 

 or ftalk,) under the generic name of Polytricum. And thofe that bear coronated or 

 angular feed vefiels at the top of the ftalk or branches, and without any remarkable 

 foot-ftalks, I have alio placed under another Genus which we have called Mnium. 



°. We have difpofed thofe that bear fquamofe heads at the alae of the leaves, and 

 have thefe difpofed in three or four regular fcries along the trunk and branches, under 

 the generic name of Selago. 



HI°. Such as we have obferved to bear their feed-vefiels, in the fame manner, at 

 the alae of the leaves, and thefe placed without any determinate order, I have difpofed 

 under the generic denomination of Sphagnum, 



IV . We have clafled fuch as have fmall fimple heads placed at the alae of 

 the upper leaves, and thefe difpofed into oblong fpikes, under the name of Lyco- 

 podium. 



V e . Thofe that bear ftnall warted heads upon the very leaves, we have ranged un- 

 der the appellation of Hypnum. *j
