Vaccinium vitis-idosa (Lian.) — Yery scarce, and unhealthy-looking here. 

 This plant has been recorded from several of the mountains I 

 examined in Mayo and Gal way, but I found it only in the present 

 situation. It appeared to me very rare indeed, and I was always 

 on the look out for it.

 1650; Croaghpatrick, 1740 to 1570; Twelve Bens (Muckanaght), 

 1900 to 1470. Yery scarce. On Croaghpatrick it is plentiful, 

 and very large and luxuriant. In the present locality it is very 

 rare. Never on quartzite. 



Cystopteris frayilis (Bernh.) — Yery rare in this the only Mayo habitat. 

 Maamturk range (Maumeen), 1100; Twelve Bens (Muckanaght), 

 2130 to 1600. Yery rare in the west, and quite alpine in its 

 mountain localities ; does not occur on the quartzite.
