98 ENGLISH BOTANY. 



M. Crepin (in the fourth fasciculus of his notes, p. 49) considers 

 this as a hybrid between C. remota and C. vulpina, while other authors 

 regard it as a hybrid between C. remota and C. muricata.

Kootstock very densely ca^spitose, ^rith very shortly creeping chor- 

 dorrhizal branches, but no elongate stolons. Stems slender, stiff, 

 acutely triangular, very rough below the spike. Leaves about as long 

 as the stem, linear, channelled, very rough on the margins towards the 

 apex, bright deep green, not glaucous. Spike very long, decompound, 

 greatly interrupted below, with a foliaceous bract at the base usually 

 equalling or slightly exceeding the spike. Spikelets 6 to 15, fusiform, 

 the lower ones spicately compound, the upper simple, all male at the 

 base or at the base and apex, female in the middle or at the middle 

 and apex, except the uppermost ones, which are often wholly male ; the 

 lowest or only 1 or 2 of the lowest spikelets with long foliaceous bracts. 

 Glumes of the female flowers ovate, acute, pale reddish-bro^vn with 

 broad white scarious margins, as long as the fruit. Fruit erect, pale 

 brown, substipitate, lanceolate, plano-convex, with 3 to 5 slender ribs 

 on the back and numerous faint ones on the face, rather gradually 

 acuminated into a rough-edged shortly-bifid beak not half the length 

 of the rest of the fruit. Nut "ovate-elliptical" (Bab.). 



In woods and by the margins of ponds. Rare. Qunarr Copse, Isle

A puzzling plant, bearing much resemblance to C. axillaris, espe- 

 cially in the dried state, but it grows in denser tufts, the stems are 

 more slender and rigid, the leaves darker green, more evidently chan- 

 nelled, the spike longer; the lower spikelets in both plants are com- 

 pound, but in C. axillaris the primary spikelet has several smaller 

 secondary ones at its base; while in C. Boiininghausiana the secondary 

 spikelets are placed on the rachis, one above the other, the primary 

 spikelet being consequently much longer. In C. Boiminghausiana 

 the gliunes are browner tluui in C. axillaris, witli well-marked white
