NOTES ON HIGHLAND PLANTS. 155 



Norvegiae prope Christianiam, Blytt ! Ab habitu C. vaginata 

 colore livido-glauco totius plantae longe differt. Bracteae vagi- 

 nan tes. Vaginae foliorum integerrimse." — P. 0. Lang, in ' Cari- 

 cineae Germanicae et Scandinavian' Linnea (1851) vol. 24. Nyman 

 places it as a subspecies of C. panicea L. My specimens appear 

 much nearer to that than to C. vaginata ; but I do not yet clearly 

 understand the differences, owing to their shabby condition. They 

 were gathered in torrents of rain.— *0. capillaris L. Stob Ban (97). 

 No doubt simply overlooked before, being one of the commonest 

 "alpines." — C. binervis Sm. Exceedingly variable. With glaucous 

 leaves, in very wet ground, Mamore Forest. Nearly 4 ft. high, on 

 the heaths above Loch Assynt.— C. flava L. Ascends to 3000 ft. 



on Meall Garbh, Ben Lawers. — C. (Eden Ehrh. Sea-coast, 

 Durness. 



Phleum pratense L. A very slender state of this [fide Haeckel), 



with small oval heads, grew at over 2000 ft. above Lochan-na- 

 Laii' 



ige. 



Ayrostis alba L., c. maritima Mey. Coast near Durness ; 

 frequent.— A. vulgaris With, {fide Haeckel). A very dark and 

 compact-flowered form grows on Ben Lawers, at fully 3500 ft. — b. 

 pumila (L.). Meall Garbh (ascending to 3000 ft.) Cliffs above 

 Lochan-na-Lairige. Roadside, Altnaharra. — c. nigra (With.). 

 Plentiful in oat-fields, Lawers. 



Deschampsia cmpitosa Beauv., b. brevifolia Parn. In several 

 localities about Lawers. Specimens from ledges on the W. side of 

 Ben Lawers are named by Prof. Haeckel " var. alpina Gaud." — c. 

 pseudo-alp ina Syme. Ben Nevis. Ben Klibreck. Coniveall. — Var. 

 pallida Koch, which I reported doubtfully from Betty Hill, last 

 year, was found in beautiful condition, in the neighbourhood of 

 Durness. — D. alpina Roem. & Schult. Ben Lawers; flowering. 

 Ben Nevis (fide Haeckel); viviparous only.— *D. fie.vuosa Trin. 

 Plentiful, E. side of Ben Klibreck (107). 



Arrhenatherum avenaceum Beauv., b. nodosum Reichb. Abun- 

 dant and well-marked in oatfields at Lawers. 



Phragmites communis Trin., b. nigricans Gren. & Godr. Bogs 

 about Altnaharra. 



Molinia ccerulea Moench, b. depauperata (Lindl.). Mamore 

 Forest. Heath near Loch Enboll (108). — Var. minima Bab. 

 Below Stob Ban, at 2000 ft. I rather doubt the value of these 

 " varieties." 



Poa annua L., var. supina (Schrad.). Wet shale, Ben Lawers, 

 above 3000 ft. A form scarcely separable from this, but with green 

 mstead of variegated spikelets, grows in mossy rills on Coniveall. 

 Prostrate. I have seen specimens from the tableland above Corne 

 Ceannder, S. Aberdeen.— P. glaum Sm. A tall plant from Meall 

 Garbh, which appeared to tone down on exposed rocks into the 

 ordinary form of this, was sent to Prof. Haeckel, who writes :— 

 " This is, I think, the true glaucu Sm. ; which, however, I cannot 

 separate from the P. casta of the same author." I do not yet 

 kaow how to distinguish /?. Balfourii from it, though there clear y 

 «« at least two forms in the Ben Lawers district. — l\ nemoralu
