Two feet and more high. Leaves rough, filamentous near the base. 



Spikes very long, erect. Cal. glumes lanceolate, dark brown, 

 ft Sterile spikes several on a culm (in C. Isevigata mostly solitary). 

 * Stigmas 2. 



39. C. acuta (slender -spiked Carex), sheaths none, bracteas 

 long foliaceous, fertile spikes long cylindrical acuminate slen- 

 der erect when in fr., fruit oval swelling subacuminate entire 

 at the point, culm acutely angular scabrous. E. B. t. 580. 



HAB. Moist meadows and watery places, frequent. Fl. May. If. .

 ** Stigmas 3. 



40. C. paludosa (lesser common Car ex), sheaths none, bracteas 

 very long foliaceous, cal. of the sterile spike obtuse, fertile 

 spikes cylindrical obtuse, fruit oblongo-ovate acute bifid at the 

 point striated. Lightf. p. 566 (C. riparia p.). E. B. t. 807. 



HAB. Banks of rivers and ditches, common. Fl. May. If- 

 Two feet or more high. Leaves very broad, keeled, rough. 



41. C. riparia (great common Carex), sheaths none, bracteas 

 rery long foliaceous, cal. of the sterile spike acuminate, fertile 

 spikes scarcely pedunculated broadly cylindrical acute, fruit 

 ovate subacuminated bifid at the point. Lightf. p. 565 (C. 

 acuta). E. B.t. 579. 



HAB. Sides of ditches and rivers, common. Fl. May. I/. 

 Larger than the last, with much broader leaves and spikes; and well 

 distinguished by the acuminated cal. scales of the sterile spike. 



42. C. Icevlgata (smooth-stalked leaked Carex), sheaths elon- 

 gated shorter than the flowerstalks, bracteas foliaceous, fertile 

 spikes drooping cylindrical, all the cal. acuminated or mucro- 

 nate, fruit ovate triangular with rather a long acuminated 

 beak bifid at the point. E. B. t. 1387. 



HAB. Marshes in Angus-shire, G. Don. Cardenden, 4 m. N. W. 

 from Kirkcaldy, Mr. Chalmers. Marshes N. of Milngaire and wet 

 woods E. of Mugdoch-castle, Hopk. Fl. June. 3/. 



One foot and a half high. Leaves broad, but rather short. It has 

 rarely more than 1 sterile spike ; but its similarity to the follow- 

 ing species induces me, as Smith has done, to place it in this di- 

 vision. Besides the difference in the fruit, the want of a sheathing 

 base to the bracteas will always distinguish C. vesicaria from this 

 species. 



43. C. vesicaria (large -fruited Bladder Car ex) > sheaths none, 

 bracteas foliaceous long, fertile spikes cylindrical slightly droop- 

 ing, cal. lanceolate, fruit broadly ovate inflated subulato-rostrate 

 deeply bifid at the point. Lightf. p.' 567 (C. inflata). E. B. 

 1.779. 



HAB. Bogs and marshes. Fl. June. I/ . 



One foot and a half high. Leaves rather broad. Culms acute, angu- 

 lar. Fruit tawny, very large, shining, much inflated.
