176 THE FLOE A OF BRECHOU. 



OphioglOSSUm VUlgatum, L. Common Adder's Tongue.— Xative. The 

 type is not found on Brechou. The var. ambiguum, C. & G., occurs very 

 sparingly on a grassy bank near the pool on the north coast. Mr. 

 Marquand considers it identical with the L'Ancresse Common plant.

 Islands, but has a wide distribution, being found in Scilly, Wales, 

 Donegal and Orkney.
