Dr. Bromfield remarks that this species invariably blooms a 
month before G. binervis. It is distinguished from that plant by 
its colour, more graceful female spiculse, the acuminate and longer 
cuspidate squamae, the elliptic, more equally triquetrous perigy¬ 
nium, which is closely applied to the achenium, of an olive-green 
colour dotted uniformly with small reddish points ; a longer and 
more slender rostrum ; and by its broader leaves. Smith says the 
male spiculse are usually two, but, like Bromfield, I have only ob¬ 
served one. 
I have never seen any specimen from the north of Europe, and 
it is not noticed by Fries or Andersson. No one has found it in 
North America since Greene. His specimen is in Herb. Hooker.
