PLANTS OF W. SUTHERLAND AND CAITHNESS 171 



becomes remarkably fine, and sometimes has the flowers bluish, 

 instead of the usual white. It is plentiful near Strathy Point. 



E. horealis Towns. 109. A strong, large-flowered form occurs 

 plentifully by the roadside, four miles west of Thurso. Small 

 states abound on Dunnet Links. 



E. gracilis Fr. 108. Barren heaths at Melvich and Strathy ; 

 but it seems to be rather scarce in the district. 



E. citrta Wettst. 108, 109. Broad-leaved coast-forms, closely 

 resembling the original plant of Fries, and superficially approaching 

 E. latifolia, are locally plentiful near Melvich, and east of Eeay. 



Bartsia Odontites Huds., var. -'' litoralis Reichb. 109. By 

 small ponds, at Lower Dounreay, east of Eeay, and four miles 

 west of Thurso ; passed by Mr. Arthur Bennett, but not extreme. 



Bhinanthus monticola Jord. 108. Locally plentiful on high, 

 heathery ground, east of Strathy ; flowers of a peculiar treacly 

 brown, as in my Glen Doll plant determined by Sterneck. 



B. . On the grassy cliffs at Melvich we found a Yellow- 

 rattle, evidently near B. stenophyllus, but perhaps distinct ; the 

 flowers were pale yellow, and the seeds have a rather broad 

 wing. 



Melampynmi pratense L., var. " hicms Druce. 108. Boggy 

 moorlands, south of Melvich. 



Lamium molucellifolimn Fr. {intcrjiiedium Fr.). 108. In the 

 Hotel kitchen-garden at Melvich this is luxuriant, associated with 

 L. piuyiireuni L. ; intermediates (probably hybrids) are not un- 

 common there. Mr. Bennett writes : — " Neuman, in Sveriges Flora 

 (1901), p. 173, considers that intermedium Fr. is L. imrpureum x 

 amjAexicaule." If so, the apparent absence of amplexicaiile from 

 places where intermedium (a fully fertile plant) abounds is hard to 

 account for. 



Plantago major L., var. " intermedia Syme (non P. intermedia 

 Gilib.). 108. To this I refer a small form, with hairy leaves 

 and scapes, found sparingly in damp, stony ground, south of 

 Strathy Point. 



P. Goronopus L. 108, 109. On cliffs, west of Melvich, and 

 in plenty at Dunnet Bay, we found a biennial plant, having leaves 

 mostly broad, acutely toothed, and both foliage and scapes densely 

 covered with white, spreading hairs, which may be var. latifolia 

 DC, as defined by Wilhams, Prodromus Fl. Brit., p. 366. 



Euphorbia Cyparissias L. 108. To this must, I beheve, be 

 referred a small Spurge, found growing (one good patch) in sandy, 

 submaritime soil near Farr Bay. It was almost prostrate, with 

 crowded, very narrow, glaucous leaves, like young larch-shoots. 

 Probably a recent escape, as we had not met with it on several 

 previous visits. Bracts red. 



Bet'ula puhescens Ehrh., var. microphylla E. S. Marshall. 108. 

 A birch-wood of considerable extent, above the Armadale Burn, 

 appears to consist mainly, if not entirely, of this. 



Carex incurva Lightf., var. ■'' erecta Lange. 109. Extremely 

 scarce among rocks just above high-water mark, east of Eeay. 



C. disticha Huds. 109. With darker glumes than usual ;
