116 MONOECIA—TRIANDRIA. Carex. 



p has smooth fruit, which in this case appears to constitute no 

 specific difference. 



By the description this is shown to be a very variable species. 

 Yet it is not the only one which varies in the number of the 

 harren. catkins, or in having some barren ^ore^s at the top of 

 the fertile catkins, which latter circumstance occurs in the last 

 described. 



With regard to its name, the Carex in question has been unfortu- 

 nate. It was first called ^acca by Schreber, and, in the year 

 following, glauca by Scopoli. Hudson ought to have retained 

 one of these, had he been informed of them, when he first de- 

 scribed the plant in his 2nd edition 3 but he took the appellation 

 of recurva from Morison's synonym. I might now perhaps have 

 attempted to restore^acccr, as most prevalent on the continent j 

 but as Willdenow has sanctioned recurva, and he is one of the 

 best writers upon this genus, this name, being in itself unex- 

 ceptionable, may as well remain.
