The spongy perigynium and the dense hairs separate this spe¬ 
cies from G. montana and G. ericetorum, with which it is asso¬ 
ciated by European authors, and ally it to G. lanuginosa and 
G. jiliformis. Kunth refers C. Thuringiaca , Schk. f. 155, to G. 
glauca, and I defer to his opinion, though Koch refers it to 
G. tomentosa. "Why he should suppose that Willdenow’s plant 
was different from Schkuhr’s, I know not. Kunth had examined 
Willdenow’s specimen, and there is no evidence that Koch or 
Lange, who equally refers Schkuhr’s to 0. tomentosa, had seen 
either.

ferioribus omnino femineis ; perigyniis majoribus pilosis, ner¬ 
vis paucis remotis, faciebus planis; squamis masculis mucro-

On the death of Mr. Nuttall, I obtained the Carices in his Her¬ 
barium, and have been enabled to correct the description I gave 
of this species in the ‘ Linnean Transactions,’ in which I mistook 
the terminal abortive female florets for male ones. I noticed in 
that description the resemblance of the species to the G. gynobasis, 
Villars, which has since been discovered in New Mexico. 
Through the kindness of Dr. Torrey, I have had the opportunity 
of seeing the plant of Parry, from St. Diego, a very poor speci¬ 
men. There are but five in Nuttall’s collection, of which I have 
figured the best.
