218 Dr. BooTT on a species of Carex 



I had observed the fact of C.pulla, Good., being the true C.saxatilis, Linn., 

 by an examination of the Linnean and Banksian herbaria, and corrected the 

 error of Goodenough in Hooker's 'Brit. Flora,' ed, 4. 1838, without having 

 been aware of Hartman's observation, which I met with in the ' Ann. des Sc. 

 Nat.' vol. xi., published in 1839. 



I am informed by Mr. Robert Brown, that a single specimen of this species 

 was discovered in Scotland first by the Rev. Mr. Stuart of Luss, and sent to 

 Lightfoot, who declared it to be a Linnean species ; but to what species he 

 referred it, Mr. Stuart had forgotten, as he told Mr. Brown, who on August 11, 

 1793, showed Mr. Stuart, then at Killin, specimens which he had found that 

 day on Ben Teskerney, a mountain at the head of Glenlochai, near Loch Tay, 

 the station of Mr. Stuart's specimen. 



Don, in his ' Herb. Brit.,' fasc. 8. 190, states that he found it on Ben Lomond 

 in 1789 (the year after the death of Lightfoot), on Ben Lawers in 1793, and on 

 Ben Nevis in 1 794 ; and that he sent it that year to Dickson, who acknowledged 

 it as an undescribed plant. The specimen figured in the ' Linn. Trans.' iii. 1. 14. 

 (1795) is in 'Herb. Smith,' recorded there by him as the plant so figured; it 

 was received from Mr. J. Mackay as gathered on Ben Lawers in 1793, and is 

 with two other specimens from the same mountain gathered by Mackay in 

 1796. 



Linnaeus, in the 'Sp. Plant.' 1753, quotes with a query under C.saxatilis, 

 " Micheli, Gen. 63. t. 32. f. 4," which Lightfoot refers, perhaps correctly, to 

 C. montana, Linn., and which, as Willdenow (Sp. Plant, iv. 274) remarks, cannot 

 apply to C. saxatilis or C. rigida, as the character " capsulis subhirsutis" would 

 prove. 



The characters distinguishing C. Grahami from C.saxatilis, Linn., as will be 

 seen on a comparison between them, are the greater height of the first ; the 

 more numerous and cylindrical spikes, of a ferruginous colour ; the more in- 

 flated and elongated, bifurcate, nerved perigynium, twice the length of the 

 scales ; and the proportionately narrower leaves, which are shorter than the 

 stem. 



C. saxatilis, Linn., is described by all those who particularly notice the 

 fruit as having a nerveless perigynium. Mr. Babington, it is true, in his 

 ' Manual,' p. 342, says the fruit is " slightly nerved ;" but he remarks, that the
