Hab. — Ben Lawers, from 1070 to 11 30 m. Ben Ein, from 976 

 to 1070 m. Ben Dothaidh, above 915 m. Specimens from all three 

 mountains in Herb. Brit. Ben Lawers (E. S. Marshall, 1887, n. 

 199, n. 894, 1 89 1, n. 84, C. P. Hurst, 1906). Ben Ein (E. S. 

 Marshall, 1889, n. 198). Ben Dothaidh (E. S. Marshall, 1893, n. 

 1012). The long-fruited form mentioned in the description was 

 found by Messrs. Marshall and' Hanbury on Ben Ein. The refer- 

 ence-numbers are taken from the type-specimens, and are not cited 

 by Mr. Marshall in his English description of the plant. 



Mr. Marshall also states on the label that his plant proved 

 distinct from C. alpina and C. danica by five years' cultivation. In 

 all three stations it grows in company with Cerastiiuji arcftcum, and 

 may be presumed to belong to a dying-out arctic vegetation. Mr. 

 Marshall also identifies with this plant an example of C. alpina in 

 Herb. Kew. gathered by H. C. Watson near the summit of Ben 

 Lawers in 1832.
