32 ANNALS OF SCOTTISH NATURAL HISTORY 



50. Cochlearia arctica, Schlecht. Mr. Marshall thinks it possible 

 that a peculiar smooth-podded plant found on the upper part of Ben 

 Lawers might be referred to this species, but its admission to the 

 British list is not yet sufficiently definite. 



51. Cochlearia alpina, Watson. Ascends to 1175 m. on the 

 mountains of the Breadalbane district, and probably rarely descends 

 below 6 10 m., a plant of alpine springs, rills, and wet rocks (" Fl. 

 Perthsh." 66). On Ben Ein up to about 1070 m. (E. S. Marshall 

 and F. J. Hanbury). Ben Ein (E. S. Marshall, 1889, in Herb. Brit). 

 Ben Lawers (Herb. Kew. and C. P. Hurst, 1906, in Herb. Brit. 

 but no height given on either specimen). Ben Lawers (W. 

 Gardiner, 1842, in Herb. Brit.). Stob-Coire-an-Easain, Glen 

 Nevis, at 1037 m. (E. S. Marshall, 1896, in Herb. Brit.). Top of 

 Ben Lawers (J. Carroll, 1864, in Herb. Brit.). On all the damp 

 ledges of rocks on Snowdon and Carnedd Llewelyn (Banks's herb. 

 1773, in Herb. Brit.). 



52. Cochlearia grcenlandica, L. Ben Ein, from 1006 to 1070 

 m., also on Ben Lawers, at a high level (E. S. Marshall and F. J. 

 Hanbury). For a critical note on this plant by Mr. Marshall, and 

 the only good figure which has been made of it, see " Journ. Bot." 

 1892, p. 225, t. 326 a, where the writer states that he suspects it is 

 often biennial. 



Fam. 19. RANUNCULACE^E. 



53. Thalictrum alpinum, L. Alpine rock ledges up to the 

 summit of Ben Lawers (" Fl. Perthsh." 45). " Ben Lawers in Bread- 

 albane" (R. Brown, 1794, in Herb. Brit.). Within 10-12 feet of 

 the top of Ben Lawers (G. C. Druce). Descends to 274 m. in 

 Donegal. 



54. Ranunculus acer, L. Ascends to the summit of Ben Lawers 

 ("Fl. Perthsh." 51). "At considerable heights on Ben Lawers, 

 Breadalbane" (R. Brown, 1794, in Herb. Brit.). Ascends almost 

 to the summit of Ben Lawers ("Cyb. Brit." i. 87). Ben Nevis, at 

 1026 m. (J. Sadler in "Trans. Proc. Bot. Soc. Edinb." xiii. 50-54 

 [1878]), and at noo m. and upwards ("Cyb. Brit." i. 87). Cairn 

 Toul, at 1067 m. (F. J. Hanbury, 1887, ex "Journ. Bot." 1890, 

 1 80). Descends to sea-level in Cork. 



f. Nathorstii, G. C. Druce in "Ann. Scot. Nat. Hist." 1900, 

 1 6 6. Up to 1070 m. on Ben Lawers. 



f. humilis, G. C. Druce in "Ann. Scot. Nat. Hist." 1904, 

 115. At 1037 m. on Ben Dearg, in Ross-shire. 



Var. piimilus, Wahlenb. " Fl. Lapponica," 159. Corrie
