In a former number of this work we gave a figure and defcription of the Carex pendula, one of the largefr, as we^ 

 as raoft diitinct fpecies of this genus ; we here prefent our readers with three more of this numerous and difficult 

 tribe. Our motive for publishing them in the lame number is, that they may the more readily be compared together, 

 and their feveral diftinguifhing characters be more forcibly imprefTed. 



In herborizing it is a practice with me to endeavour at acquiring a perfect 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 latisfaction often terminated in fome new difcovery, which has placed the plant in a 

 more confpicuous light than before ; fuch has been the happy refult in the prefent inftance. In pafling through Bat- 

 terfiea meadows I had frequently noticed the three Carices here figured, which I was taught to confider as the fame 

 fpecies, varying only from particular circumitances, but fo great was the variation, that 1 never could perfectly recon- 

 cile myfelf to the idea. I (hall here relate the feveral characters which ftruck me firfr, 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
