The figure of Gmelin quoted as above by Mr. Hudson for 
this plant, if it had a mid-rib would be a much better represen- 
tation of the F. rubens of the English botanists than 24. 1, of 
the same author; I have never seen a specimen of Mr. Hud. 
son’s F. fimbriatus, bat suspect that he may have only had 
before him a large and perfect plant of the F. rubens.

This plant is subject to great variations, as is evident from 
the figures. It is green, purple, or brownish yellow. Cartila- 
inous in the narrower, membranaceous and pellucid in the 
roader parts. Branches ribless, all of one height; from 2 to 
4 inches high. It has been considered by our botanists as the 
F. ceranoides of Linneus, but besides other differences, its want 
of terminating tubercles or masses of seed.vessels will always
