Agrostis nigra not in Ireland. 



An Agrostis which is abuudaut on islands in Lough Carra, which I 

 took to be a form of A. alba, I labelled by inadvertence A- nigra, a species 

 not yet recorded from Ireland. The specimens went with others to a 

 specialist, who, curiously enough, passed the name as correct, and the 

 plant was referred to as /?. nigra in my paper on the flora of Lough Carra 

 {Irish Nainralist, xv., 210, 1906). Only lately I noticed the discrepancy, 

 and, for safety's sake, submitted the specimens to Mr. Druce, whose 

 verdict is A. alba var, coarctata (Hoffm.).

Helleborine longifolia in Co. Derry. 



Last August I found this species (formerly known as Epipactis pahtstris 



Crantz) growing in a damp meadow between Magilligan Station and the 



sea coast. It has never been discovered previous!}^ in Co. Derry, and was 



thought to be extinct in the North-East. The only previous records for 



that region were one for Co. Down made by Templeton in 1820, and one 



for Co. Antrim b}^ Dr. David Moore in the ist edition of •' Cybele Hiber- 



nica," 1S66.

Erica Mackaii on TJrrisbeg. 



In view of the limited range of this Heath, it may be worth recording 

 that, in company with the members of the Central Committee for the 

 Survey and Study of British Vegetation, at the end of August last I 

 found a small colony of it on L^rrisbeg, about a quarter of a mile N.E. of 

 the summit, at about 600 feet elevation. Its former stations do not exceed 

 200 feet in elevation. The locality furnishes some confirmation of 

 Ogilbj-'s Letterdife record of 1845, where the plant has not been found 

 since. This station lies about a mile east of the Urrisbeg one, both 

 being situated about three miles south of the plant's headquarters at 

 Craigga More.
