lakes. But on the bar which separates Lady's Island 

 Lake from the sea it grows in the greatest profusion for 

 about a mile, save for a tract of about 250 yards where 

 the plant is absent ; it is somewhat unevenly distributed on 

 the bar, but it occurs in the greatest luxuriance and 

 abundance at the two extremities, to the exclusion of 

 other vegetation. There are patches of a hundred square 

 yards or more, growing so thickly together as to make 

 their white foliage visible a long way off; many plants 

 are bushy, quite small undershrubs, spreading at the base, 

 and densely covered with flowers. (See Plates i and 2.) 



The bar referred to is about thirty to forty feet in 

 height, with a slope of about 190 paces long on the land 

 side, and one of 64 paces long on the seaward side. Its 

 crest is broken by depressions over which the sea may 

 wash at the highest tides, as drift seaweed was seen fifty 

 or sixty yards on the landward side of the crest. The 

 channels, which are shown on all the recent maps as 

 communicating between the lakes and the sea, no longer 

 exist, broad bars of sand occupying their places ; deposi- 

 tion rather than denudation seems, therefore, to be taking 

 place on this portion of the coast, and there is no fear of 

 the plant being destroyed by the inroads of the sea. 



In the mile and a half between Lady's Island Lake 

 and Carnsore Point, I saw only twenty plants scattered 

 singly, or in twos and threes at irregular intervals, three 

 of them being close to Carnsore Point itself At this 

 point its distribution ceased, for although I rounded the 

 Point and walked along the coast northwards for a couple 

 of miles to the little village of Carne, I saw no more of it. 

 I afterwards walked along the east coast from Carne as far 

 northwards as the town of Wexford, but Diotis did not 

 reappear.
