178 TRANSACTIONS OF THE [Sess. lxxxvii 



Bennett, " Suppl. Top. Bot./' p. 31 (1905) ; and Spence, 

 " Flora Orcadensis," p. 21 (1914) ; but, having been planted 

 in an artificial plantation of trees, and being still confined 

 to that plantation, it has no claim to be included in the 

 flora of Orkney, any more than the exotic trees in the 

 same plantation.] 



[Rubus spectabilis, Pursh (Jide D. K. Hughes).— Rocky 

 ravine at waterfall, 120 feet above sea-level. Burn of Laro, 

 Rousay, 24th May 1922, H. H. Johnston. Not native. 

 Planted by man, but by whom I have not as yet ascertained. 

 Ten shrubs, 4-7 feet high, in full flower, with large rose-pink 

 petals, only seen by me at the Burn of Laro. This pretty- 

 flowered Bramble is a native of North America, and, on 27th 

 May 1922, I also saw it growing in a plantation of trees at 

 Trumland House, Rousay.] 



[Rosa gallica, Linn, {fide William Barclay).— Grassy bank at 

 roadside on the outer side of a garden stone wall, 20 feet above 

 sea-level, Castlegreen, Saint Ola, Mainland, 28th August 1922, 

 H. H. Johnston. Not native. Planted by man both inside 

 and outside the garden of Castlegreen House. Very rare. 

 Plants sparingly in flower-bud. This species is recorded from 

 the same station by Dr. G. Claridge Druce in " Bot. Exch. 

 Club Secretary's Report for 1920," vol. vi, part i, p. 123 

 (September 1921), but, being merely a cultivated garden 

 plant, it has no claim to be included in the flora of Orkney.] 



[Cratcegus Oxyacantha, Linn., probably (fide D. K. Hughes, 

 who states that "it is not possible to decide in the absence 

 of both flowers and fruit ").— Near the edge of grassy cliffs 

 at seashore, 50 feet above sea-level, Berstane, Saint Ola, 

 Mainland, 19th October 1922, H. H. Johnston. Not native. 

 Three shrubs, planted by man, only seen by me on the top 

 of the highest part of the clifTs between Berstane Bay and 

 Wideford Burn.] 



[Sambmus nigra, Linn. — Whin and elder hedge, 50 feet 

 above sea-level. The Loan, Gyre, Orphir, Mainland, 11th 

 August 1879, H. H. Johnston ; not native, planted by the 

 late James Johnston of Coubister on 6th April 1841, plants 

 in flower ; and marsh, 80 feet above sea-level, between Fursan 

 and the Burn of Woodwick, Evie, Mainland, 28th July 1922, 

 H. H. Johnston, not native, planted by man along with a few 

 bushes of Salix viminalis, Linn., forming a small clump of
