THRINCIA NUDICAULIS IN PERTHSHIRE 45 



THRINCIA NUDICAULIS, BRITT., IN 

 PERTHSHIRE. 



By WILLIAM BARCLAY. 



IN August last Mr. David Campbell, a keen botanist and 

 one of the most promising recruits of the P.S.N.S., brought 

 me a specimen of Tkrincia nudicaulis, Britt, which he had 

 found by the roadside at the policies of Dupplin Castle. 

 He recognised the plant from having seen it in Haddington- 

 shire, where it occurs in various places in considerable 

 quantity. On visiting the station at Dupplin I found the 

 plant growing in patches along one side of the road, at the 

 base of the boundary wall, for a distance of about a hundred 

 yards or more. It was not to be found on the other side 

 of the road. 



In Dr. White's " Flora of Perthshire," under its synonym 

 Leontodon hirtus, two old records are given. One " in a 

 field below the garden at the Earl of Kinnoull's seat near 

 Perth (Mr. Miller in Smith's ' Fl. Brit.,' 1800) has not been 

 verified." The other, " Steirck-an- Lochan, Ben Lawers " 

 (W. Gardiner, 1842), is probably an error. 



On reading this, one would suppose that Mr. Campbell's 

 discovery was simply a verification of the first of these old 

 records, for Mr. Miller's station, as given in the " Fl. Brit," 

 is almost the same as Mr. Campbell's. But on referring to 

 the " Flora Britannica " itself, I found, to my surprise, that 

 there is no such record in that work. There the plant is 

 given under the name Hedypnois hirta, with amongst other 

 synonyms Leontodon hirtum, Lin., but no localities are men- 

 tioned except " in pascuis et ericetis glareosis." After some 

 trouble, however, I found the key to the mystery. In the 

 "Addenda et corrigenda" to Smith's work, at page 1401, 

 No. 684, we read : " TJdaspi Jiirtum. In a field below the 

 garden at the Earl of Kinnoul's seat near Perth." In the 

 " English Flora " of the same author (1825), vol. iii. page 167, 

 Lepidium hirtum, the TJdaspi hirtum of the Flora, is stated 

 to occur " in Perthshire, near the seat of the Earl of Kinnoul.
