and by Fin Lougli. A curiously stunted variety, with broad 

 leaves, and stem an inch and a-half high, occiu's at 2400 to 2300 

 on the Ascokeerin ridge, Mweelrea ; and on the summit of Delphi 

 mountain, 2550. 



Salix herlacea (Linn.)— I^Tephin, 2450 to 1880 ; Corslieve and ISTephin- 

 beg, 2320 to 1700; Curraun Achill, 1560; AchiU, 2100 to 1900; 

 Croaghpatrick, 1850 to 1750; Mweelrea group, to 1850; Maam- 

 trasna range, 1850; Maamturk range, 2000 to 1600; Benchoona, 

 1900 to 1680; Twelve Bens, 2130 to 1570. Possibly occurs 

 lower on low summits, since it prefers the tops and ridges of 

 moimtains in perfectly exposed situations. This is the common- 

 est alpine' plant, and occurs on very nearly all the mountains I 

 visited. More abundant on Mweelrea than elsewhere ; on the 

 northern summit it is the chief vegetation straggling amongst 

 moss. 



Carex rigida (Good.) — ISTephin, 2500; Corslieve and JSTephinbeg, 2320 

 to 1600, and at 860 feet at Scardaun Lake ; Achill, 2030 to 1825 ; 

 Mweelrea group, to 1640. Next to the last, this is the com- 

 monest truly alpine species in the west ; they are frequently in 

 company on wet ledges, and both thrive on the quartzite. 



MWEELEEA. 



2590 feet. 



Ry77ienophyUum imilalerale (y(\\ldi.) — Corslieve, 1750; Achill, 1730; 

 Ben Gorm, 2080. Prequent at low levels in both counties. 



Delphi Mt. (Mweeleea Geoup). 

 2550 feet. 



Achillea millefolium (Linn.) — At 2350 above Lough Brawn on Loughty 

 Mt. Met with nowhere else on the mountains ; here it was 

 stunted, consisting of a few rigid radical leaves without stem or 

 flowers. Frequent below. 



Plantago lanceolata (Linn.) — ^A very diminutive form, with slightly 

 succulent, narrow., lanceolate leaves, about an inch in length, and 

 a flowering stem not much higher. Eesembles the form of P. 

 maritima, mentioned above, in general appearance. Ordinary P. 

 lanceolata finds upper limits — on Croaghpatrick, 1630 ; Mweelrea, 

 1520. 



Summit oe Ceoaghpateick. 



2510 feet. 



Poa ani\ua (Linn.) — Ben Gorm and Glenamorig, 2200 ; Buckoogh and 

 Mweelrea, 1900. Accidentally distributed amongst these heights. 

 Probably the seeds are transported hither by sheep, as this grass 

 only occurred at great heights in the neighbourhood of their runs.
