176 The Irish Naturalist. 



Ball ; Urtica pihilifera, an alien nettle, noticed by the present 

 writer ; and the rare grass Festuca unigluniis, found on the 

 sandy shore at Baldoyle by Mr. H. C. Levinge, where, last 

 season, not knowing at the time of Mr. Levinge's discovery, I 

 was delighted to find fine specimens of it. In the Irish 

 Naturalist for 1893 (p. 174), Mr. David M'Ardle, who has dis- 

 covered so many interesting liverworts among the rocks cf 

 Howth,' added the little club-moss, Selaginella spiiiosa, to the 

 flora. In the Joztrnal of Botany for 1894 (p. 76), I record 

 seven Brambles not known on Howtli hitherto, nor most of 

 them in Co. Dublin or in District 5 ; these were gathered on a 

 pleasant July day spent with a number of members of the 

 Belfast and Dublin Naturalists' Field Clubs. In the same 

 journal (p. 359) I add R. viicans to this list. So far as I am 

 aware, this completes the enumeration of published additions 

 to the Flora of Howth. 



Of unpublished additions, it is probable that interesting 

 notes are in possession of some of the many wild-flower lovers 

 who spend summer da3^s or weeks on the breezy slopes of Ben 

 Edar; and if the present sketch has the result of bringing to 

 light information that otherwise might remain unrecorded and 

 unknown, then it will not have been written in vain ; in this 

 way, the very incompleteness of my notes may prove their 

 greatest merit. 



PLANTS NOT INCLUDED IN THK "FLORA OF HOWTH." 



Crambe maritima, L.— Not yet quite extinct at Howth. I found it 

 last year sparingly on the gravelly strand of Ireland's Eye. Formerly 

 grew on the south side of Howth {Irish Flora, 1833), but "Mr. Hart says 

 that it has been extinct there for many years. 



Reseda suffrutlculosa, L. — Has grown for many years near the 

 Forge, Sutton. — jMiss R. Mahaffy. Apparently naturalized here. 



Silene ang^Iica, L., var. S. quinquevulnera, L. — On the railway 

 bank near Howtli station. — Miss R. Mahaffy. Perhaps merely casual here. 



Rubus scaber, W. & X.— Howth Demesne.— Rev. C- H. Waddell. 

 " A hirsute variety." — W. M. Rogers. 



R. silvaticus, W. & N.

The above were collected mostly in the Demesne ; a few of them near 

 the Bailey ; the exact locality of each was not noted. The plants were
