Mr. J. BalPs Botanical Notes of a Tour in Ireland. 31 



Bryum punctalum abundant in fructification. Returning to 

 Dublin, and proceeding northward along the shore of the bay, 

 Linum angustifolium may be found plentifully on banks be- 

 tween Clontarf and Howth ; on the sandy sea shore Euphorbia 

 paralia is abundant. Close to the ruined church of Kilbarrick 

 may be seen the five British species of Papaver, P. somni- 

 ferum being as truly wild as it is ever seen in Britain. In ad- 

 dition to many rare or local plants mentioned by Mr. Mackay I 

 have found in the sandy fields near this spot, Bromus erectus, 

 Festuca rubra, and Avena pubescens, and in a marsh near 

 Baldoyle, Heliosciadium inundatum. On banks above the vil- 

 lage of Howth I have collected a species of Sagina, differing 

 in appearance from the described British species, and agree- 

 ing very closely with a specimen from Sussex, named by Mr. 

 Borrer the Sagina filiformis of Pourret. For many rare plants 

 in the neighbourhood of Portmarnock, stations are given in 

 Mackay's Flora Hibernica : I may observe that the species 

 of Viola, named in that work V, Curtisii, and which agrees 

 with cultivated specimens from a plant so named by Mr. 

 Borrer, is not the V, Curtisii of the original description, which 

 agrees with V. lutea in having the centre lobe of the sti- 

 pules undivided, being probably no more than a variety of that 

 plant ; whilst the plant in question, which is abundant on the 

 sandy coasts north of Dublin, and which I have seen also in 

 the counties of Down and Derry, is apparently very nearly 

 allied to the V, saxatilis of continental writers, which in com- 

 mon with all the many named forms of V. tricolor, has the 

 middle lobe of the stipule dentate. On the sandy warren near 

 Portmarnock I noticed a tetrandrous species of Cerastium, 

 which appears to be identical with the C. pedunculatum, de- 

 scribed and figured by Mr. Babington in vol. ii. p. 197. PI. VI. 

 of the Magazine of Zoology and Botany. I may mention ha- 

 ving noticed in the county of Dublin the Fumaria parviflora,for 

 which only a single station is given in the c Flora Hibernica/ 

 At Clogher Head, in the county Louth, I found in a corn field, 

 just above the village, Thlaspi arvense and Lamium incisum, 

 both rare in Ireland ; and on the summit, Trifolium striatum 

 and Trigonella ornithopodioides ; and on steep banks over the 

 sea Statice spathulata and a white variety of Antliyllis vulne^
