25. C. Buxbaum'ii, Wahl. (Fig. 1408.) (hoary Carex). ‘“ Spikelets 
three to five, terminal one barren at the base, fertile, sessile, except 
the lowest, which is on a short stalk, and sub-remote ; fruit oblong, 
oval, obtuse, triquetrous, nerved, bi-dentate, pellucidly asperate, 
shorter than the ovate cuspidate scales.” 
Hooker, British Flora, ed. 4. vol. i. p. 385-—C. polygama, Schkh. 
X. G. g. f. 76.—C. canescens, Linn. 
“ Root creeping. Stem one to two feet high, erect, acutely tri- 
angular, rough, leafy at the base, and clothed with purple sheaths, 
which are torn and reticulated at theiredges. Leaves straight, shorter 
than the stem, middle spikes smallest, more or less approximate. 
Bracteas rough, auriculated, but without sheaths, the lowest some- 
times longer than the stem, upper ones setaceous. rutt glaucous, 
green, stained with brown, shorter at the base of the spikelets than 
the cuspidate scales, which are brown, with a pale green nerve.” 
Habitat.—On a rocky island in Lough Neagh, Ireland.—-Mr. 
Moore. 
Perennial; flowering in July. 
“ Linneus confounded C. alpina, Vahl. (C. Vahlit, Schkh.) and 
C. curta, Gooden. with this species. The specimens from Lapland 
are of the present plant. ©. curta was described by the late Bishop 
of Carlisle, in the Linn. Trans. v. 2. p. 145, in 1792, eleven years be- 
fore Wahlenberg ; in Act. Holm. (1803) described the present species 
under the name of C. Bux-baumii. The original name of C. canescens 
must be restored io it. Boott. in Hooker, British Flora, ed. 4. vol. i. 
p. 335.” 
We have given the above description from Hooker, rather than 
describe foreign specimens, with which we are only acquainted, 
though they do not in any respect differ from the above description. 
26. C. atra’ta, Linn. (Fig. 1409.) Black Careaz. Spike compound ; 
spikelets three to five, ovate, pedunculated, the terminal one erect, 
barren at the base, the others fertile, drooping ; lower bractea leafy ; 
stigmas three ; fruit roundish ovate, compressed, with a short scarcely 
bifid beak, as long as the dark ovate acute scales; stem smooth ; 
root tufted.
