Flirt her Notes on the J'lora of County Dublin. 55 



CuscutaTrifoIIly Bab. — (i.) Two large patches on Trifolium praiense 

 between Ballyboghil and the Wren's Nest, August, 1894, and (2) abundant 

 in a sandy field at the northern extremity of Portrane peninsula, 

 September, 1894. In the second station the plant attached itself chiefly 

 to Anthyllis Vulnerana which appeared to have almost completely driven 

 out a sowing of Trifolhun pratense. The only previous county record is 

 that of Dr. W. G. Smith for Ballybrack, 1868. {Dub. Nat. His. Soc. Proc, 

 vol. v., p. 198). 



Orobanche minor, Sni. — Very abundant (1) in sandy fields to the 

 north of Portrane peninsula on ^////^j'/ZzV and on Trifolium hybridum and 

 T. pratense, September, 1894, also (2) abundant on T. pratense in a field 

 above the hotel at Malahide, where I gathered spikes fully 18 inches in 

 height at the close of September last. The only previous record for Co. 

 Dublin is Shennick's Island, 1893 (/. Nat., Vol. ii., p. 283). This and 

 the preceding species would appear to be spreading in the county. 



Mentha sativa, Linn. — (i) Watery places by the roadside near 

 Cockle's Bridge, Garristown, August, 1894, and (2) by the Dodder near 

 Newtown, Tallaght, September, 1894. Often confounded, no doubt, 

 with M. aquatica, and perhaps frequent in the county. 



Calamlntha Acinos, Clairv. — A single well-grown plant in a 

 stubble field by the Royal Canal, E. of Clonsilla, October, 1894. 

 Previously recorded from three other county stations, Portmarnock, 

 Portrane, and near Tulla Church, Carrickmines. Though the first 

 published record is due to Mackay (^Additions, 1859- 1860), a specimen in 

 Glasnevin Herbarium labelled: — "Portmarnock, October, 1854, Thomas 

 Chandlee," seems to show that Mr. Chandlee was the first to observe 

 the plant in the county. A rare species throughout Ireland. 



Stachys arvensis, linn. — This species, apparently spreading in the 

 county, though still uncommon, I observed during the year at three new 

 stations— (i) Garristown, (2) Rush, and (3) Ballyedmonduff. 



Anagrams arvensis, Linn., var. caerulea. {A.carulca, Schreb.) Of 

 this pretty blue-flowered variety of the Scarlet Pimpernel, I gathered a 

 single plant in September last in a corn-field near Raheen Point, Portrane. 

 There appears to be no previous published record for the county ; but 

 Mr. R. M. Barrington of Fassaroe, has shown me a specimen gathered 

 by his uncle, the late Mr. Richard Barrington, at Seapoint in 1858. The 

 variety seems to be very rare in Ireland. 



Chenopodium nriurale, Linn.— A few plants in waste ground at 

 the angle of Oldcourt cross-roads south of Tallaght, 1893. Now very 

 rare in the county, but once much more common if the older records 

 may be trusted. 



Lemna g^ibba, Linn.— In great abundance in the old mill-pond in 

 Balbriggan, August, 1894. The conspicuously buoyant masses of this 

 species often rising distinctly above the surface of the water make it 

 readilv distinguishable, by habit alone, from the common Z. minor. 



Ophrys apifera, Huds.— (i) Sparingly in dry pastures among the 

 gravel eskers W. of Drimnagh Castle, June, 1894 ; (2) on the railway bank 

 at foot of Killiney Hill, July, 1894. 



Juncus obtusiflorus, Ehrh.— (i) In a shallow drain at Garristown 

 Bog, August, 1894 : (2) very abundant in marshy ground by the northern 

 shore of Portrane, spreading for fully a quarter of a mile, September, 

 1894 ; and (3) abundant in a marsh above Saggard, Sef)tember, 1894. The 

 plant seems to thrive inland quite as well as in maritime stations. At 

 Cxarristown, 11 miles from the nearest sea, I gathered specimens upwards 

 of 5 feet in height, and those from the Saggard station, fully 13 miles 

 from the nearest sea, seem quite as vigorous as the Portrane plant. 



Carex laevigrata, Sni.— In a marsh on the S.E. slope of Kilmashogue 

 Mountain at 700 feet, July, 1894.
