128 ANNALS OF SCOTTISH NATURAL HISTORY 



was admitted as a naturalised plant under that name in the ninth 

 edition of the " London Catalogue of British Plants." In January of 

 this year Mr. James Groves asked me to compare our Scotch plant 

 with authentic examples of L. perennis, L., in the herbarium of the 

 British Museum, as he was not satisfied with the identification. On 

 doing so, I agreed with him that our plant was not perennis ; and an 

 examination of the Lupines in the Kew Herbarium a few days later 

 proved that it was undoubtedly L. Nootkatensis, Donn (in Sims' 

 " Botanical Magazine," pi. 1311). All the examples that I have seen 

 either growing or collected in Scotland belong to the one species. 

 I was interested to find in the Kew Herbarium two specimens con- 

 tributed by the Rev. M. J. Berkeley, (rather imperfect but easily 

 recognisable,) the earliest from Scotland that I have seen. Of 

 these one was labelled "Z. poly-phyllisst Naturalised on the banks 

 of the Dee near Aboyne, Aug. 1862"; the other bore " Lupinus 

 littoralis, Doug. Rocks in the river Dee, near Dinnet, Aberdeen- 

 shire ; from seed raised by the Rev. M. J. Berkeley, July 1871." 

 It has thus been well established beside the Dee near Aboyne for 

 nearly forty years at least. In January 1893, in a note in this 

 journal, I called attention to its prevalence in Scotland, under the 

 name L. perennis, L., as I then believed it to be. I am glad now 

 to be able to correct this error. 



In that note some observations were recorded of the action of 

 the lupine in changing the bed of the Dee and in diminishing the 

 growth of alpine plants along the lower course of the stream. Dur- 

 ing the past eight years these results have been very evident ; but a 

 further change has followed. The- lupines raise the beds of shingle 

 and water-borne sand and soil above the reach of all except the 

 highest floods in winter ; but their success leads to their undoing. 

 Grasses such as False Oatgrass, Couch Grass, etc., and other coarse 

 native perennials, take a firmer hold year by year of the ground so 

 gained, and the lupine tends to be crushed out. The great beds 

 of it are no longer seen where they were so conspicuous about 

 1890, and it is driven to new shingle beds and to the margins still 

 liable to be covered every winter by a moderate rise of the water.

" Mimulus luteus, Linn." of British Floras. This is another 

 native of Western North America that must be known to us in 

 future by a different name. Professor Edward L. Greene has made 

 us aware of the confusion that long existed as to the identity of 

 M. luteus, L., the name having been given by him to a plant 

 brought from temperate South America, and figured by Pere Feuille'e 

 as a new species of Gratlola in 1714. This plant was not intro- 

 duced into European gardens until more than a century later. Soon 

 after 1800 the Mimulus now so well known and widely naturalised 

 with us was introduced into European cultivation from the N.W.
