112 EXGLISI! BOTANY. 



tains of Keny and Tipperary in the south of Ireland, and on most of 

 the high mountains in the north. 



England, Scotland, Ireland. Perennial. Summer. 



Plant growing in loose tufts with the greater part of the rhizomes 

 above ground when on rocky ledges, but buried when on stony 

 level places or in marshes. Stems 3 to 15 inches high, thick for tlic 

 size of the plant. Leaves broad in proportion to their length, usually 

 about ^ inch broad, numerous at the base of the stems, and in the 

 bai'ren tufts proceeding from the stolons. Male spikes about ^ inch 

 long ; female spikes ;f to f inch long. Fruit ^ inch long. 



A well-marked species, distinguished by its thick rigid stems, stiff 

 reflexed broad leaves, with the margins revolute when dried, short 

 spikes, and ribless fruit. 



In marshes on Loch-na-gar, and also on little Craigendal, near the 

 station for Astragalus alpinus, however, I have gathered a form which 

 closely approaches C. aquatilis : it has the stems quite smooth at the 

 summit and the glumes reddish-brown. Lower spike usually at some 

 distance from the others, longer, more slender, and more lax at the 

 base than in the common form.

Rootstock subca^spitose, shortly creeping, with elongate stolons. 

 Stem erect, rather stout, stiff, trigonous, smooth throughout. Leaves 

 nearly as long as the stem, erect, rather stiff, linear, flat or channelled, 

 very slightly rough on the margins, yellowish-green, slightly glaucous; 

 sheaths entire, not filamentous at the margins, all with laminaj except 

 the very lowest. Male spike 1 or rarely 2, cylindrical or fusiform- 

 cylindrical. Female spikes 2 to 4, rather remote, subsessile, except 

 the lower one, which is usually more or less longly stalked, erect, cylin- 

 drical, with the fruits densely imbricated all round. Bracts foliaceous, 

 the lowest one usually equalling or exceeding the apex of the male 

 spike, with 2 short prominent oblong nearly free brown scarious 

 auricles at the base. Glumes of the female flowers ovate-oval, obtuse 

 or acute, reddish-brown, vnth broad green or pale midribs with con- 

 colnrous margins, as long and usually nearly as broad as the fruit.
