NOTES ON HIGHLAND PLANTS. 281 



referring it here ; but the fruit seems typical. Still, it is a very 

 marked form, and quite constant in its native station. — R. auri- 

 covius L. Ascends to fully 2000 ft. in Corrie Winter, Clova. No 

 personal authority for 90. 



Caltha palustris L. On Clach Leathad, Kingshouse, I found the 

 type ascending to 2500 ft., associated with var. 7ninor. 



"^Fumaria densijiora DC. Railway-bank near Ballinluig Station 

 (89). Just inside E. Perth. Casual only. 



Arabis sagittata DC. The alpine state of this, about Clova {e. g. 

 at the head of Glen Doll, and the Falls of the Unich), bears some 

 superficial resemblance to A. ciliata, and is doubtless the plant 

 recorded under that name by Gr. Don, as Watson suggests. 



Cardamine ^^ratensis L. A state with very large leaflets occurs 

 near Dalnaspidal ; it did not fruit, and has produced double flowers 

 in cultivation. — "^^Cfiexiiosa With. Near Fort Wilham (97). It 

 ascends to 2000 ft. near Clova. 



Cochlearia granlandica L. (non Sm.). I believe that a plant 

 gathered by me in fruit, high up on Ben Lawers, in 1887, is 

 referable to this species. It has flowered well in the garden, both 

 this year and last, and has not in the least lost its dwarf, compact, 

 very distinct habit. The radical leaves are small, very numerous, 

 on foot-stalks from ^-1 in. long, ascending, entire or with one or 

 two obsolete teeth on either side ; flowers much the same as in 

 aJjnna Wats. The seedlings are equally typical. I have before 

 seen it somewhere suggested that C. arctica Schlecht. was the true 

 name for this Ben Lawers form ; and that is apparently a synonym. 

 Slugs are so fond of these plants that I have failed to get ripe fruit. 

 The pouches in my herbarium specimens are longer than those of 

 alpina, which appear to be subglobose. That plant has also a 

 straggling habit, and is on a larger scale. — *C'. dcinica L. Summit 

 of the Little Culrannoch (90). This appeared to me very different 

 fi'om all ^'alpina'' that I had seen before, and Dr. Lange names it 

 as above ; a determination assented to by Prof. Babington. It 

 seems to be a biennial, plants sent home having died before the 

 approach of winter ; whereas alpina survived, and is still quite 

 vigorous. The appearance is decidedly towards danica ; and I 

 suspect that the ''alpina'' of the Teesdale meadows, which seems 

 to die after fruiting, would be equally so named by Dr. Lange. The 

 occurrence of this species at such an altitude is not in itself at all 

 improbable, though in Britain, at least, it has hitherto been regarded 

 as exclusively a coast-plant. 



"^'Suhidaria aquatica L. In Lochan Mathair Etive (98) ; abundant. 

 *Cerastium arcticum Lange. E. side of Ben Nevis (97), among 

 loose stones, at over 2500 ft. 



Stellaria Holosiea L. Ascends to quite 2000 ft., near Clova. 

 '^^Sagina Linncei Presl. Clach Leathad (98). 

 "^Rosa mollis Sm. (fide Baker). Above Braedownie, at the 

 entrance to Glen Doll (90) ; both white and pink-flowered. 



Saxifraga rividaris L. was already flowering upon Ben Nevis on 

 June 23rd. — 8. sponhemica Gmel. This is certainly a very protean 

 species. Mr. Baker remarked on a bright green, densely -tufted
