than the stems ; spikelets 4-6, sessile, very close together, ovoid, 

 brownish green, about inch long, chiefly female, with a few male 

 flowers at the base ; fruits flat, winged, shortly beaked. Moist 

 meadows ; common. Fl. June, July. Perennial. 



24. C. lagopina (Hare's-foot Sedge). Similar to C. leporina, bu< 

 smaller, and there are usually only 3 or 4 spikelets ; fruits flat, 

 but not winged. Damp rocks and grassy places on mountains in 

 Aberdeenshire and Inverness-shire ; very rare. Fl. July, August. 

 Perennial. 



25. C. elongata (Elongated Sedge). Much taller than the two 

 preceding species, often 2 feet high ; spikelets longer, narrower, and 

 not so close together as in C. leporina, and the fruits are not winged. 

 Marshes ; rare. Fl. July, August. Perennial. 



3. Spikelets several, the terminal one or more usually wholly male, 

 the others wholly female, or sometimes male and female 



* Fruit with a short beak 



I Style 2-branchcd ; fruit plano-convex 



26. C. elata (Tufted Sedge). Densely tufted ; stems 1^-2 feet 

 high, surrounded at the base by the brown sheaths of the leaves, 

 the outer of which are split into ragged fibres ; leaves &-J inch 

 broad ; spikelets 3-6, -2 inches long, the terminal one and the 

 upper portion or whole of the next male, the others female ; lowest 

 spikelet usually shortly stalked ; glumes dark brown or black, often 

 with a green midrib ; fruit almost flat, with a short point. Marshes ; 

 common. Fl. June. Perennial. 



27. C. acuta (Slender-spiked Sedge). More luxuriant than 

 C. elata, with long, flaccid leaves and leafy bracts ; female spikelets 

 often 3 inches long or more ; glumes narrow and acute ; fruits 

 ribbed. Wet places ; not uncommon. Fl. June. Perennial. 



28. C. rigida (Stiff Mountain-Sedge). Appears to be a dwarf 

 Alpine form of C. elata ; it is about 6 inches high, with short, flat, 

 ri^id leaves, short spikelets, and ribless fruits. Stony and wet 

 places on mountains ; rather common. Fl. June, July. Perennial. 



29. C. aqualilis (Water-Sedge). A very tall leafy plant with 

 slender spikelets ; it resembles C. acuta, but it has ribless fruits, as 

 in C. rigida. Alpine bogs and river-sides ; rare. Fl. July. Peren- 

 nial. 



30. C. salina is a very variable species, a form of which has been 

 found in Caithness ; it is allied to C. aquatilis, but the glumes of 

 the lower part of the female spikelets have a long, rigid point, and 

 the fruits have many veins. Fl. July, August. Perennial.
