248 ANNALS OF SCOTTISH NATURAL HISTORY 



(White in "Scot. Nat." i. 122 [1871]). Descends to sea-level in 

 Cork. 



30. Euphrasia Rostkoviana, var. borealis, Towns. Ben Lawers 

 and Ben Ein, between 1070 and 1130 m. ("Fl. Perthsh." 234). 

 Ben Lawers (W. Gardiner, 1842, in Herb. Brit. but no height 

 given). Dwarf specimens. 



31. Euphrasia Foulaensis, Towns. On Cairn Gorm up to 

 1070 m. (E. S. Marshall, 1898, in Herb. Brit.). Mr. Townsend 

 does not give any limits of height for these species in his mono- 

 graphic revision. 



32. Alectorolophus crista-galli, Bieb. Ascends to 1022 m. on 

 mountains of the Breadalbane district (" Fl. Perthsh." 234). Neither 

 Rev. E. S. Marshall nor Mr. G. C. Druce indicate any heights 

 above 1000 m. for segregates of this species; so that I leave Dr. 

 White's statement as I find it, " the altitudinal range of the lowland 

 form usually stops far below the height at which the alpine variety 

 begins to appear." Descends to sea-level in Cork. 



Fam. 8. LAMIACE/E. 



33. Thymus serpyllum, L. Ascends to 1130 m. on rocks in 

 the Breadalbane district (" Fl. Perthsh." 239). Descends to sea- 

 level in Cork. 



Fam. 9. PLUMBAGINACE^E. 



34. Armeria pubescens, var. plaiiifolia, Nyman, Consp. Summit 

 of Ben Lawers (\V. Gardiner, 1842), and of Snowdon (J. F. Young, 

 1839), and of Cam Tual (H. N. Ridley, 1883) all three speci- 

 mens in Herb. Brit. At 1130 m. on Ben-na-Bourd (Watson, 

 1832). Cliffs of Ben Dearg (in Ross-shire) up to noo m. (G. C. 

 Druce in "Ann. Scot. Nat. Hist." 1904, 171). Syn. Armeria 

 vn/gans, var. planifolia, Syme, " Engl. Botany," ed. 3, vii. 158, t. 

 1153 (1869). Syme's variety is not at all a satisfactory one, being 

 founded on cultivated specimens in Watson's garden, and not on 

 the original high alpine plant, which was not described at the time. 

 All the three specimens mentioned above seem to me to be distinct 

 from Armeria pubescens, and severally agree with Spanish specimens 

 of Armeria alpina, W. Syme mentions also this plant, but he 

 certainly does not clearly distinguish his variety from it, and 

 adduces only the most trivial separating character (and this might 

 readily have been modified under cultivation). Gardiner also must 

 have had this in mind, since he labels his specimen " Armeria 

 maritima, var. alpina, Hopped Unless more definite evidence is 

 forthcoming, I should be very much disposed to consider these 

 high alpine examples as true Armeria alpina, W. All three of the 

 specimens are much nearer to the latter than to A. pubescens, Link,
