NOTES ON A TOUE IN N. SCOTLAND. 167 



Thalictnim culliniun Wallroth. 108." Melness Sands, Tongue 

 Bay, associated with T. dunense ; also on rocks at Ardsgionaich 

 Poiut, at the N.W. end of the Bay. 



Kamuiculus Flammula L. var. radicans Nolte. 108. Sandy shore 

 of Loch Naver, Altnaharra ; many of the specimens very charac- 

 teristic, but shading off into the ordinary form, and some quite 

 erect, though in other respects just like the prostrate, rooting state. 

 — Fi. scoticus E. S. Marshall (A', j^etio/aris ejusdem, non Bonpland, 

 Humboldt, & Kunth). 108. Lochan Hacoiu, near Tongue; Loch 

 nan Uan, below Ben Klibreck, Altnaharra. Our recent observation 

 of this plant in a wild state has confirmed us in the belief that it 

 should be separated from Fi. Flammula as a good subspecies ; as Mr. 

 Symers Macvicar has noticed, it appears to occur only on stony 

 lake-margins over a subsoil of peat. — Ft. Steveni Andiz. 108. Rocky 

 bay about a mile W. of Melvich. 109. Sparingly in a damp hollow 

 on Holburn Head, together with a curious dwarf state of R. Flam- 

 mula. — R. bulbosus L. 107. Sandhills, Brora; Golspie Links. 

 108. Melness Sands. — R. Ficaria L. 108. Ascends to 1800 ft. on 

 Ben Laoghal. 



Caltha radicans Forster. 108. ''^ By the Ribigill Burn, above the 

 bridge which crosses it about a mile from Tongue ; scarcely differing 

 from C. palustris in leaf-characters — it may perhaps be the var. 

 zetlandica Beeby, which we have not seen. 



Papaver duhium L. 107. Golspie. 



Neckeria claviculata N. E. Brown. 108. Tongue; only seen at 

 one spot. 



Cardamine jlexuosa With. 107.* Dunrobin Glen, Golspie. 



Draba incana L. 107. The small state mentioned by Syme as 

 growing near Tain is abundant on Golspie Links. 



Coclilearia officinalis L. 109. Very luxuriant in a gully on 

 Holburn Head. A peculiar scurvy-grass grows on the coast of the 

 Dornoch Firth, between Edderton and Tain, 106, with leaves much 

 like C. anglica, but approaching C. aljjina in the pods, which are 

 strongly reticulate when ripe. Prof. Hausskuecht suggests that 

 this may be a hybrid ; if so, it is pretty sure to be C. groenlandica 

 X officinalis ; but we did not notice the former thereabouts, and its 

 seeds appear to be perfect ; the shape of the fruit is also against this 

 view. — C. groenlandica L. 107.* Shores of Loch Fleet, near 

 Golspie; much eaten down by rabbits. 108. S.E. shore of the 

 Kyle of Tongue, on decomposing mica-schist. 109. Abundant and 

 very dwarf in short turf, Holburn Head. 



Sisymbrium Thalianum J. Gay. 107.* Golspie; Biovsi [TJilaspi 

 arvense is not uncommon at both these places). — [S. Sophia L. 

 107.* Shore at Golspie ; only one plant, evidently a mere casual.] 



Cakile maritima Scop. 107.* Coast between Brora and Golspie ; 

 also by Loch Fleet. 



Helianthemum Chamacistus Miller. 107. Scarce and very local 

 on cliffs half-way between Brora and Golspie. 



Viola ericetorum Schrader. 107.* Near Brora. — V. Curtisii 

 Forster. 107.* Between Brora and Golspie ; the same form which 

 is abundant on Dunnet Links, Caithness.
