species, neither halophile nor hydrophile, turned up as side 

 issues to the examination of the coasts and watery places. 



I may at once summarize as follows the best plants which 

 I have to record : — 



New to the British Islands, Glyceria festucseformis. 



New to Ulster, . . Valerianella Auricula. 



Chenopodium rubrum. 

 Carex divulsa. 



New to District XII., . Geranium columbinum. 



New to County Down, . Glyceria plicata. 



lyastrea spinulosa. 



Kxtensions of range, or new stations for rare plants :-- 

 Thalictrum dunense. Ceratophyllum demersu'n 



Crambe maritima. Juncus obtusiflorus. 



Agrimonia odorata. Typha angustifolia. 



Ivigusticum scoticum. Potamogeton plantagineus 



Merteusia maritima. Cladium Mariscus. 



Atriplex portulacoides. Carex teretiuscula. 

 Hydrocharis Morsus-ranse. 



Considerable interest attaches to the first of these, Glyceria

 1830, inasmuch as it is not only a species hitherto unknov/n in

 Mediterranean as that of several of the famous plants of South- 

 west Ireland. According to Nyman {Consp. FL Eu?: and

 N. Italy, Dalmatia, Turke}^ S-W. Russia, and (?) by a lake in 

 Hungary. 



The discovery of the plant is, in one sense, due to a farmer 

 who, wishing to take a crop of hay off one of his meadows 

 fronting the lough, railed in a portion of the foreshore along 

 with his field. This allowed the maritime vegetation to shoot 

 up, while everywhere else along the vshore it was closely cropped 

 by cattle. While traversing this portion of the beach, which 

 lies just north of the rocks at Marlfield Bay, my eye was at 

 once caught with this tall upright Glyceria. It grew between 

 two and three feet in height, with stems slightly arching at the 

 top, and leaves a foot long, and was immediately distinguish- 

 able from G. maritwia, which grew near, by the above features,
