LEGUMINOSZ. [Lathyrus. 
It seems better on the whole, to assume that the Lathyrus 
did actually occur as recorded by Dr. Smith, and that it 
held its ground there from before 1756 to at least 1845, but 
has now been lost through some change in the surface of 
these very exposed sandhills. It is well known that the 
Sea Pea in its British stations sometimes disappears for 
lengthened periods after a severe storm to reappear when a 
favourable shift in the surface takes place. Perhaps it is 
not too much to hope that this may still occur in its only 
known Irish station ; so far the plant has escaped all recent 
observation.
