Turfy bogs, frequent.' — j3. moist sandy places or heaths. — 7. 

 perhaps not rare ; marsh (now drained) near the mouth of the Pow- 

 burn, Ayrshire (1850), ^. 5,^. — Stems 6 — 8 inches or a foot 

 high, Bracteas very foliaceous, the lower one resembling the broad 

 acuminated leaves, Spikelets, and indeed the whole plant, of a yellowish 

 hue. Achene ohovate, with 3 nearly equal flat sides and thick angles, 

 very minutely and closely dotted with impressed points, at length 

 jiearly quite smooth. Our )8. is what is usually called C (Ederi by 

 .British collectors. The 7, is C. (Ederi of Andersson and the bota- 

 'nists of the north of Europe, and has much more the aspect of C 

 •extensa, but the achene is quite as in C.Jlava. It is difficult to say 

 what C, (Ederi of Smith is; the figure in E, B, is not good, but the 

 Jiccompanying description points to our 7 : it is, however, probable 

 that Smith had both the iS, and 7. in view at a later period.

 edged beak bifid at the point, glumes acute (not mucronate).
