Hierochloe odorata, Wahl. — I should like to correct a mistake 

 regarding the refinding of Hierochloe odorata recorded by Don from 

 Glen Calla. Mr. Arthur Bennett, in the "Annals of Scottish Natural 

 History," October 19 11, refers to a post-card he had received from 

 the late Mr. A. Somerville, dated 14th June 1904, in which Mr. 

 Somerville states that he possessed a letter from Mr. J. Smith NicoU 

 of Arbroath regarding this plant. In the letter Mr. NicoU says that 

 he knew a Dundee botanist who had found Hierochloe in Glen 

 Calla. I have spoken to Mr. NicoU on the subject, and he tells me 

 that the botanist he referred to was Mr. William Smith, who, however, 

 informs me that there must have been some misunderstanding, as he 

 has never seen Hierochloe^ and Mr. NicoU himself says that he has 

 been mistaken as to the plant found by Mr. Smith. On several 

 occasions in May of this year I searched the Glen, but without 

 success. R. H. Corstorphine. 



Mr. G. C. Druce ("Journal of Botany," June 19 12), in a note 

 upon Alchemilla acutidens Buser, discovered on Ben Lawers last 

 summer by Dr. Ostenfeld, refers specimens collected by Mr. E. S. 

 Marshall at Inchory, Banff, and by myself in Linlithgowshire in 19 10, 

 to that species, and quotes Lindberg's descriptions of this and 

 A. alpestris Schmidt, with which it has formerly been confused in 

 Britain. It would be well if Scottish botanists would pay special 

 attention to the genus, as A. acutidens may be expected in many other 

 counties. There is also another very distinct-looking plant which 

 occurs in Linlithgowshire for which I have been unable to obtain a 

 name so far. M'Taggart Cowan, Jr. 



Note on the Calluna-Mat Association of the Mountain Tops 

 OF the Northern Highlands. — Some description of this plant 

 association was given in the "Vegetation of Caithness" (1911), and 

 it is hoped in the near future to publish a fuller account of its geologi- 

 cal and other relations as found in the Ben Armine district. Here 

 ^ve wish to draw attention to the habit of some of the typical plants 

 of the association. These include, Calluna vulgaris, Erica cinerea 

 (frequent), Arctosiaphylos alpitia and A. uva-ursi, Thymus Serpyllum 

 (frequent), Aira flexuosa. Azalea procit7nbe7is, Lycopodium alpinum, 

 Antennaria dioica, Carex rigida, and species of Vaccinium occur 

 sometimes.
