PLANTS HXCZUBEB. 289 



A modern introduction, brought by accident, or perhaps placed out 

 from an aquarium. It certainly was not in this place eai'lier than 1880, 

 or 1881.

 at Belmont, and dungheap at Belfast ; S.A.S. Magheralin ; C.II.W.

Among wheat at Cranmore ; Templeton, 1796. Ballyronan, and Lam-

 Doubtless in every case introduced with seed.

 Malone ; Cyb. Sib. 

 An agricultural casual. 



139. Kordeum murlnum Linn.

 Meadows, and roadsides ; Flor. Belf. 



This grass is a frequent escape from tillage, and propagates spon-
