PLANTS OF CAITHNESS 169 



Lychnis dioica, L. Abundant on sea-cliffs at Duncansbay, and also 

 seen near Holborn Head. 



Cerastium tetrandrum, Curt. A large form near the White Sands, 

 and very condensed floriferous forms at Downreay, where 

 exposed to full wind and sun. A lax form grew on the Reay 

 sand-hills where sheltered. 



C. semidecandrum, L. Downreay, Holborn Head. 



C. vulgatum, Z. Occurred as a glabrous and very stunted form on 

 the sea-cliffs of Holborn Head, growing in short turf, and also 

 as a very hairy form at Reay. 



Arenaria peploides, var. diffusa (Hornem). Lax plants a foot long 

 grew out of the crevices of the sea-cliffs near Downreay, near 

 Murkle Bay. The type also occurred. 



Spergula sativa, Boenn. Castleton. 



*Buda rubra, Dum. On the railway at Georgemas. 



Sagina nodosa, Fcnzl. On the Holborn cliffs in short turf, and at 

 Reay. 



S. maritima, Don. Rather plentiful on the cliffs 250 feet above sea- 

 level, growing under the partial shelter of rocks, but there 

 subject to the sea spray. Also on low cliffs near Murkle Bay. 

 Some luxuriant specimens also seen near Downreay. 



Montia fontana, L.. var. major, All. Near Rattar Moss. 



Trifolium pratense, L. This was also conspicuous from its large 

 and bright-coloured flowers, reminding one of T. medium, 

 which I did not see. 



Anthyllis vulneraria, Z., var. Dillenii (Schultz). - - Reay cliffs. 

 But the corolla is not wholly pink with red tips, but cream- 

 coloured. That is, it is the var. Dillenii of the third, not of 

 the second, edition of Hooker's Student's Flora. The flowers 

 of plants of Dillenii from Anglesey are pink and crimson, and 

 are typical. 



Vicia cracca, Z. The beautifully blue flowers, which are conspicu- 

 ously larger than those of our Midland plant, were a great 

 ornament to the hedges near Castleton. 



V. sylvatica, Z. By the Thurso river. 



Lathyrus pratensis, Z. The flowers of this also were distinctly 

 larger than those of our southern plant. 



Rubus Rogersii, Linton. Near John o' Groat's. 



R. corylifolius, Sm. About Thurso in several places. 



Alchemilla vulgaris, Z., var. alpestris (Schmidt). Between Castleton 

 and John o' Groat's. The type grew by the Thurso river.
