This delicate species, though allied to the Ferruginece, contrasts 
in its perigynium especially, with the characteristic forms of that 
group, but I do not know where it can be more appropriately 
placed. Lange associates it with 0. sylvatica , but I think Gaudin 
more correctly allies it with his 0. Scopolii. I do not find any 
reference in authors to the terminal spike being occasionally male 
at base. Several specimens I have from Schleicher so exhibit it, 
and one is figured; nor do I find any allusion to the female 
spiculse being compound. The specimen from Reichenbach, from 
the Tyrol, occasionally has such. The other specimen is from the 
Jura, from Mr. Bentham.

"Wahlenberg renaarks that in habit it differs from all other spe¬ 
cies, no doubt in allusion to the branched culm. The American 
plant has acuminate squamae. Carey places it with C. tenella, 
from the resemblance of the perigynium. I have no hesitation 
in referring C. fulvicoma here, though the specimens are too 
young for any positive opinion.
