288 PLANTS EXCLUDED. 



128. Pinus sylvestris Linn. Scotch Fir. 

 Vide page I3i. 



129. Stratiotes aloldes Linn. Water Soldier. 



Belfast watercourse {Templeton) ; Flor. Hib. Whitehouse milldani ; 

 W. Millen. Springfield dam ; Flor. Belf. 



The origin of the plant in the Stranmillis watercourse was perhaps 

 accidental, in the milldams, there can be little doubt, it was intentionally- 

 introduced. Now extinct in all three stations. 



130. Elodea canadensis ^lich. Water Thyme. 

 Vide page 135. 



131. Orcbis pyramidalis Linn. 



A single specimen on gravelly pastures at Magilligan ; D.M. Two 

 plants on sandy shore at Ballyholme ; S.A.S.. 1873. 

 Stray plants accidentally brought, and not established. 



132. Zrls foetidissima Linn. Gladdon. 



Eiverside at Newcastle, and woods at Greyabbey ; Ir. Flor. Near Cole- 

 raine ; D.M. Plentiful in a meadow by the stone cashel at Cushendun ; 

 B.N.F.G., 1884. 



Esteemed as a medicinal plant, and frequent, therefore, in gardens, 

 from whence the wildings have originated. 



133. Colchicum autumnale Linn. Meadow Saffrox. 

 Rich meadows about the ruins of Greyabbey ; Ir. Flor. 



A garden escape— not found now. 



134. iicorus calamus Linn. Sweet Flag. 



Lakes at Hillsborough, and Ballynahinch, but most probably planted 

 there ; Templeton. In the Lagan canal at various points between Lisbum, 

 and Moira station, being specially abundant from Blaris to Kesh bridge, 

 1866, also more sparingly in the lake at Ballynahinch, 1875 ; S.A.S. 



Not an indigenous plant in Britain, and no doubt planted here, as sug- 

 gested by Templeton. The lake in Hillsborough Park is less than two 

 miles distant from the point in the canal where the Acorns is most plen- 

 tiful, and the plant could easily have been derived thence. The great, 

 creeping rootstock of the sweetflag renders its eradication difficult, and 

 thus it has existed here for, at least, a century. In the canal it is so 

 abundant as to be used for bedding cattle. 



135. Iiemna polyrrhiza Linn. 



In a flaxhole in marshy pastures below the second lock of the Lagan 

 canal; Dr. S, M. Malcomson, 1884,
