of the spikes ; beak of peiigyniura is recurved ; fertile spikes 

 distant. Var. (Ederi is smallei', and has the spikes close together. 



27. C. Distans. — This, with Fulva, Binervis, and Lwviyata, 

 form a group of which it is difficult to catch the specific characters. 

 Distans (proper) is found near the sea in brackish marshes ; distant 

 interval between the two lower fertile spikes ; Colvend. 



28. C. Fulva. — In damp places in the hills ; known by its leafy 

 stem and by the long sheath which accompanies the lowest bract. 

 Some consider it a form of Distans. 



29. C. Binervis. — So called from two green nerves or ribs on 

 the outside of the perigynium. Very like Distans, but larger and 

 stouter, often 4 feet high. Very common on dry moors and 

 similar places. The slender stems droop on all sides ; male 

 spike is neat and spindle-shaped ; bracts leafy, except tlie upper 

 one, which is veiy minute, forming scarious or callous tips to the 

 slightly slit sheath. 



30. G. Laevigata. — Like a large form of Binervis, but its male 

 sjiike is trigonous, while that of Binervis is round ; stem smooth, 

 while that of Binervis is rough at the top. I have only found 

 it on Aii-ds, a farm on the river Dee opposite Hensol. 



31. C. Fujictata. — This is the rarest Carex I have gathered in 

 the Stewartry. The Rev. Mr Fraser, Colvend, found it in his 

 parish some time ago, and specimens sent by him from Colvend 

 are still, I understand, in the Herbarium of the British Museum. 

 Two years ago he showed Dr Gilchrist and me the plant. I do 

 not think that any other person has found it in Scotland. Grows 

 only near the sea. 



32. C. Sylvatica. — An elegant Carex ; flat, broad, soft leaves ; 

 long-pedicelled, lax-flowered spikes ; very slender and droojjing. 

 In woods in damp places — Holm Glen, <fec., and at Kirk dale, and 

 at Rerrick. Linnteus tells us that the Laplanders dress it, and 

 use it for keeping their feet dry. 



33. G. Vesicaria. — This and G. Ampullacea are very like each 

 other, both having inflated perigynia — called the bladder Carex — 

 stem rough, while AmjMllacea has it smooth ; light green leaves, 

 and Amjmllacea has long, channelled, glaucous leaves. Often these 

 two grow together, and are very common in bogs and marshes, by 

 the sides of lakes, rivers, &c. 



34. G. Aniimllacea. — Bottle Carex. The pi-incipal points of 

 difTerence between this and Vesicaria have been noted above.
