172 ANNALS OF SCOTTISH NATURAL HISTORY 



*R. stenophyllus, Schur. Thurso, and near John o' Groat's, etc, 



Lamium intermedium, Fries. - - Garden ground, Scrabster and 

 Thurso. 



L. purpureum, L. John o' Groat's. 



Stachys ambigua, Sm. (S. silvaticus palustris). Thurso. 



Galeopsis Tetrahit, Z., var. bifida (Boenn.). Scrabster, John o' 

 Groat's, etc. 



*var. nova. In potato fields. A form occurred with more 

 glabrous foliage and differently outlined leaves and 

 flowers, which as yet I have been unable to match. 



Prunella vulgaris, L. The flowers of this were conspicuously larger 

 than those of our Midland plant. 



*Stachys arvensis, L. Castleton, in cornfields. 



Ajuga pyramidalis, L. We saw only the root-leaves of the young 

 plant, which were pointed out to us by Mr. Lindsay, whose 

 great kindness it is impossible to do justice to. The plant 

 likes the shelter afforded by gorse bushes, although just growing 

 out of their shade on a steep earthy cliff of glacial clay with 

 shallow loamy subsoil, and not 100 feet above sea-level. 



Plantago coronopus, Z., var. pygmcea, Lange. Common on the 

 Holburn sea-cliffs at Downreay, etc. 



var. maritima, Gren. and Godr. Near Clairdon. 



P. maritima, Z., var. latifolia, Syme. With very broad leaves 

 (nearly an inch), on a precipitous rock near Downreay. 

 Forma vivipara occurred near Downreay, also with broad 

 slightly dentate leaves. The var. dentata, Wirtgen (teste E. G. 

 Baker), a monstrous form with foliaceous bracts, also occurred 

 on the cliffs. 



var. minor, Hook, and Arnott. Scrabster, Downreay. 



P. lanceolata, Z., var. capitellata, Koch (? capitata, Presl.). Holburn 

 cliffs. Also a form near P. glareosa, A. Kerner (teste E. G. 

 Baker), at Downreay. 



Rumex crispus, Z., var. trigranulatus. Thurso. The form with 

 a tubercle on only one perianth segment was seen at John o' 

 Groat's. 



fFagus sylvatica, Z. Planted about Castleton. 



tQuercus sessiliflora, Salisb. Planted near Castleton. 



Salix repens, Z. On the Holborn sea-cliffs. 



Empetrum nigrum, Z. On the Holborn cliffs in full exposure. 



Juniperus communis, Z. By the Thurso river.
