92 ORCHIDACEyE. 



This is the most interesting plant in our local flora. Widely spread 

 across North America (and extending into Kamtschatka), it was from 

 1810 till 1892 known in Europe only from the neighbourhood of Castle- 

 town Eerehaven in West Cork. In the latter year it was discovered in 

 Co. Armagh, and has since been shown to occur in all the five counties 

 (Down, Antrim, Derrj-, Tyrone, Aimagh) which border on that lake, 

 extending up the Upper Bann to above I'ortadown, and down the Lower 

 Bann to C'oleraine. Its European centre of distribution has thus been 

 changed from S.W. to X.E. Ireland. In many places round Lough 

 Neagh it occurs in tolerable abundance. Consideralile doubt has been 

 expressed recently as to whether the Ulster plant is identical with that 

 from Cork and Kerry. Examination by experts leaves it doubtful 

 whether either is Chamisso's X. American plant. For its relation to 

 5. stricta Rydberg, a recently described American segregate, see 

 '•Irish Nat.," xv, 188. The whole matter is under investigation at 

 present.
