This has been noticed by different botanists, under the 

 names of ^^ Arenaria rubra" (perennial variety), ".4. rmdia^' 

 and even of " A. marina" but its character and appearance 

 are quite constant and recognizable, and it appears entitled to 

 rank as a distinct species. No intermediate forms approach- 

 ing either L. marinum or L. salinum have ever come under our 

 notice, and the small inland L. rubrum is still more different.

This IS no doubt the plant given in the Flora of Cork, 

 under the name of " Arenaria rubra," and as the proper 

 Lepigonum rubrum (Fries) proves to be a rare plant in.Ireland, 

 there is every "probability that nearly all the Irish stations 

 given for it belong really to L. salinum. Both forms, "L. 

 neglectum " (Kindberg) and L, medium (Fries), occur, but the 

 latter is far the scarcer of the two.
