78 MONOECIA-TRIANDRIA. Carex. 



There is now and then a fertile ^oref at the base of the barren 

 catkin, or a few barren^oreis at the summit of the fertile one. 



C. capitata, Fl.Dan. t. 372. Schk. i. Y./. 80, is always monoecious, 

 and has a smooth-edged corolla ; nor has it ever been found in 

 Britain. 



2. C. Davalliana. Prickly Separate-headed Carex. 



Catkins simple, dioecious. Fruit lanceolate, triangular, 

 ribbed, deflexed ; its angles rough towards the summit. 

 Root tufted.

In boggy mountainous situations, but rare, though very common 

 in Switzerland. 



In marshy ground in Mearns-shire, North Britain. Frof. James

 Guillon loch, Edinburgh ; Mr. Maughan. Hooker. On Lands- 

 down near Bath. Jllr. Groult, and Mr. E. Forster. On spongy 

 bogs in the county of Down, Ireland. Sherard, thejirst observer 

 of this species. Near Belfast. Mr. Templeton. 



Perennial. May, June. 



Taller than the preceding ; the root tufted, with strong zigzag 

 fibres, not creeping. Stem sometimes very rough. Catkins twice 

 the length of C. dioica, from which moreover the long-beaked, 

 more or less reflexed, strongly ribbed corolla, rough-edged near 

 the top, but not serrated as in that species, clearly distinguishes 

 the present. The generally accurate Dr. Wahlenberg neverthe- 

 less unites them ; an error almost as great as that relating to 

 my Eleocharis multicaulis, v. ].64. 



Mr. Sieber sent me specimens, from the alps of Carinthia, having 

 several barren as well as fertile^ore/y, in each catkin. 



3. Qj.puUcaris. Flea Carex. 



Catkin simple ; florets in the upper half barren ; in the 

 lower fertile. Fruit spreading, deflexed, polished, taper- 

 ing at each end. Stigmas two.
