plates have been published as far as I know, but it has been other- 
wise illustrated several times, the best figures being probably those 
by Boott (Ill. Carex 4: 150. pl. 484) in 1867. 
From its first discovery authors have felt that this plant did not 
fit in with the members of the vast and widely distributed genus 
Carex and have expressed themselves to this effect. Thus we find 
Gawler rather quaintly saying “‘ the character of our plant does not 
entirely agree with that of the Uncinia of Mr. Brown, and we have 
placed it under Carex, leaving its transposition, if necessary, to 
some one better acquainted with its kind than we profess to be.”’ 
It has accordingly seemed better to make it the type of a separate 
genus, which has been named Cymophyllus, in allusion to the un- 
dulate-margined leaves. This genus differs from Carex in producing 
but one blade-bearing leaf to a culm, which leaf is entirely without 
sheath, ligule, or midvein. 
A most careful and detailed study of the anatomy and morphology 
of this species was made by Dr. Theodor Holm in 1897 (Am. Jour. 
Sci. IV. 3: 121-128. pl. 4).
