11 Fruit downy, hairy or scabrous 



45. C. humilis (Dwarf Silvery Sedge). A densely tufted plant ; 

 stems 3-5 inches high ; leaves very narrow, much longer than the 

 stems ; spikelets 4 or 5, the terminal one male, about inch long, 

 the others female and much smaller, placed far apart almost to 

 the base of the stems, their stalks enveloped in the white mem- 

 branous sheaths of the bracts ; fruits obtuse, more or less ribbed, 

 slightly downy. Dry hills in some of the southern and south- 

 western counties, and in Herefordshire. Fl. June. Perennial. 



46. C. digitata (Fingered Sedge). Densely tufted, 6-12 inches 

 high ; leaves short ; mule spikelct about inch long ; female spikelets 

 3 or 4, all shortly stalked, more or less spreading ; flowers rather 

 distant ; bracts brown, sheathing, without leafy tips or only very 

 short ones ; fruits minutely downy. Woods on limestone hills ; 

 rare. Fl. April, May. Perennial. 



47. C. omithopoda (Bird's-foot Sedge). Very similar to the last, 

 but the female spikelets are more distant and the fruits are longer 

 than the glumes. Derbyshire and Yorkshire. Fl. April to July. 

 Perennial. 



48. C. ericetorum (Heath Sedge). Differs from C. digitata in 

 having keeled leaves and smaller, shorter, crowded spikelets. 

 Chalk hills in some of the eastern counties ; rare. Fl. April, 

 May. Perennial. 



49. C. pilulifera (Round-headed or Pill-headed Sedge). Stems 

 6-12 inches high, in broad tufts ; leaves shorter than the stems, 

 weak ; female spikelets 2 or 3, short and compact, close to the 

 terminal male one ; bracts leafy, usually short, sheathless ; glumes 

 brown ; fruits small, obovoid or nearly globose, scarcely beaked, 

 very shortly downy. Hilly pastures and moors ; common. Fl. 

 May. Perennial. 



50. C. verna (Spring or Vernal Sedge). Similar to C. pilulifera, 

 but the leaves are shorter and stiffer, the spikelets are not so close 

 together, and the lowest bract has a short sheath with a small 

 leafy point. Dry pastures and heaths ; uncommon. Fl. April, 

 May. Perennial. 



51. C. montana (Mountain-Sedge). This is distinguished from 

 C. pilulifera by the bracts having scarcely any leafy points, the 

 shorter female spikelets with much darker glumes, and by the 

 much longer hairy rather than downy fruits with acute angles. 

 Pastures and heaths in Sussex, Monmouth, Hereford, and Wor- 

 cester ; rare. Fl. April, May. Perennial. 



52. C. tomentosa (Downy-fruited Sedge). Rootstock creeping ;
