In a former number of this work we gave a figure and defcription of the Care. x pendula , one of the largeft, as well 
as moft diftind fpecies of this genus ; we here prefent our readers with three more of this numerous and 'difficult 
tribe. Our motive for publilhing them in the fame number is, that they may the more readily he compared together, 
and their feveral diftinguilhing charaders be more forcibly impreffed. 
In herborizing it is a pradice with me to endeavour at acquiring a perfed knowledge of every plant which occurs 
in all its poffible varieties ; the greater the difficulty I find in the attempt, the more minute is my enquiry. Thefe' 
inveftigations have^ to my great latisfadion often terminated in fome new difcovery, which has placed the plant in a 
more conlpicuous light than before ; fuch has been the happy refult in the prefent inftance. In palling through Bat- 
terj'ea meadows I had frequently noticed the three Carices here figured, which I was taught to conflder as the lame 
fpecies, varying only from particular circumftances, but fo great was the variation, that 1 never could perfedly recon- 
cile myfelf to the idea. I fliall here relate the feveral charaders which ftruck me firft, and gave me the idea of their 
being different. It was the pointed, triangular, black heads or male fpikes of the riparia, the bluntnefs not only of
