XCI. — Report on the Ploea oe the Mountains oe Mayo and Galwat. 

 By H. C. Haet, B.A. 



[Read, January 22, 1883.] 



Having received a grant from the Eoyal Irish Academy' for the pur- 

 pose of continuing my examination of the Botany of the Irish mountains 

 in 1882, I resolved to devote my exertions to those situate in Mayo 

 and Grdway. In a little less than a month, during two visits in June 

 and July, I traversed all the mountains of important height — about 

 2000 feet and upwards. Some were so utterly barren that a single 

 visit sufficed. I have, however, taken each chain separately in my 

 report and dealt with its peculiarities, and will, therefore, merely 

 enumerate them here, starting at the north-east. The figures are 

 the height in feet, from the Ordnance Map. 



In Mayo : — 



Nephin, 2646. 



Knockaffertagh, 1695; Birreencorragh, 2295; andBuckoogh,. 1935. 



Laghtdauhybaun, 2369; Corslieve, 1785; JSTephinbeg, 2065; XJlena- 



morig, 2067 ; and others of the range. 

 Curraun Achill, 1784 and 1715. 

 Achill, 2204 and 2192. 

 Croaghpatrick, 2510. 

 Mweelrea group ; Delphi Mt. 2504 and 2474 ; Ben Gorm and Ben 



Cregan, 2383 and 2283 ; and Mweelrea, 2688 and 2610. 



In Mayo and Galway : — 



Slieve Partly or Maamtrasna group; Devilsmother, 2131; Maam- 

 trasna (Formnamore), 2239 and 2209. 



In Gralway : — 



Maamturk range ; Leckavrea, 2012; Corcogemore, 2045; Maumeen, 

 2076, &c. ; Letterbrickaun, 2195; Maamturkmore, 2300; and 

 others of the chain. 



Benchoona, 1975. 



Bennabeola or Twelve Bens ; Benbaun, 2395; Ben Lettery, 1904; Muc- 

 kanagbt, 2153, &c. 



A short sketch of the botany of eacb of these groups will be given, 

 and finally a general view of the vertical range of plants throughout 

 the Mayo and Galway mountains. As heretofore, I refrain from com- 

 paring these results with those obtained in other parts of Ireland until 



the whole be completed.
