Kunth thought this species was a form of C. bracliystachys, 
Schrank ; but it essentially differs from it in its evaginate bracts, 
and the roughness of the perigynium at the apex, and the scat¬ 
tered hairs on the leaves and vaginse. Kunze confounded it with 
0. astivalis, Curtis, as I have remarked, p. 54. I have figured 
the best specimens I have. Those of n. 1 are the C. miser of 
Buckley, which I owe to the kindness of Dr. Gray and Mr. 
Tuckerman; and n. 2 is a specimen from Herb. Hooker, sent by 
Kunze from Rugel as 0. Rugeliana (exparte).

This was undoubtedly the C. leporina of the FI. Lap. of Lin¬ 
naeus, and is in his herbarium under that name; but in the FI. 
Sueoica he described the C. ovalis, Good., under the name of C. 
leporina, quoting the FI. Lap. plant,—thus confounding the two. 
Authors have since generally adopted the name of C. leporina for 
the plant of the FI. Suecica. As Andersson remarks, there are 
forms very like C. festiva, but distinguished by the inalate perigy¬ 
nium. Wahlenberg says “ Capsulse tantum acutse et hreviter ros- 
tellatse (uec acuminatse), colore fulvescentes vel rufescentes, unde 
tota spica eundem colorem acquirit.” I find they vary iu size 
and form, often acuminate with a cylmdric elongate rostrum. 
The form with 4-6 spiculse is the “ var. /3. pleiostaohya” of Drejer. 
It is distinguished from C. leporina by its spike, perigynium, and 
alpine habitat.
