BOTANY. 



PHANEROGAMS. 



Brachy podium plnnatum, Bcauv., an addition to the 



Irish flora. 



On August 7tli last I found this handsome grass covering a Large 

 extent of surface on the sandhills at Tramore, count}' Waterford, where 

 it is, in niy opinion, undoubtedly native, the plants growing with 

 it being Rubus ccesms, Ajumophila arwidinacea, Cynoghssiwi officinale, Viola 

 Curtish', Rosa spinosissima, &c., and no cultivation or houses, except one 

 small cottage a mile distant, within three miles of it. Mr. Arthur 

 Bennett, F.Iv.S., has kindly verified the identity of my specimens. This 

 species was recorded for county Cork man}^ years ago, but it has not 

 since been found there, and all subsequent writers have agreed that some 

 other plant must have been mistaken for it, I therefore have much 

 pleasure in now adding it with certainty to our list of indigenous Irish 

 plants. 



Cork. R. A. Phii^i^ips. 



Arenaria tenuifolia, Linn., in Ireland. 



While waiting for a train at Ballybrophy railway station, Queen's 

 County, on June 14 last, I strolled along the line, and noticed quantities 

 of an unfamiliar-looking plant which subsequently proved to be the above 

 species, for which I can find no previous Irish record. A few weeks 

 later (July 21) I was surprised to find a good deal of the same plant on 

 the railway near Bansha, county Tipperary. The plants accompanying 

 it in each case were Linan'a zn'scida, Cerastitim triviale, Sagina procinnbens, 

 Senecio vulgaris^ &c. Owing to its growing so freely in both these 

 localities I look forward to hearing of its discovery in many directions 

 along our Irish railways. Mr. Arthur Bennett, F.L.S., and Mr. N. Colgan, 

 M.R.I. A., have kindly identified my specimens. 



Cork. R. A. Phii,i,ips. 



To Mr. Phillips's note I may add that during the last two seasons 

 I have been turning up Arenaria tenuifolia in several parts of Ireland. 

 It was first found in the large gravel-pit by the railway at the 

 Curragh of Kildare in June, 1897, where it grew abundantly and 

 luxuriantly, in company as usual with plants of doubtful standing — 

 Alyssum calycinum, Linaria viscida, Calainintha Aciuos., Orobanche viiJior, 

 Senebiera Coronopus. Since then I have found it in four other 

 places: — County Roscommon, on the railway a few miles N.W. of 

 Athlone ; county Carlow, railway at Milford ; King's County, railway at 

 Banagher ; North Tipperary, at the terminus of the derelict railway at 

 Portumna. In every case the plant grew on railway ballast, accompanied 

 by Linaria viscida; and in all but the Carlow station, Cerastitim tetrandrttm 

 was also present. It is a remarkably inconspicuous plant, though not 

 very small, and presumably this accounts for its very late addition to the 

 Irish flora. Probably it has been spreading in recent years, like its com- 

 panion, L. viscida.
