watched its progress so unremittingly, that I had at length the satisfaction of receiving from him 
specimens in the state represented at tab. 83. f. f. 3. 4. 7- 12 ; and had soon after, from Ambleside, 
the still greater pleasure of having forwarded to me, by the same friend, an individual with the 
capsule burst from the frond. With equal ardor Dr. Taylor commenced his researches in the 
neighborhood of Dublin, where he had the good fortune to find capsules fully ripe, and discharging 
their seed, on the mountains at Lough Bray, on the 31st of March, 1814. These he communicated 
to me, with the remark, that he believes the capsules to be of very short duration ; “for that it was 
not till after repeated visits to the same spot, and a most laborious search each time upon his 
hands and knees, that he was at length able to discover them. The weather was remarkably warm, 
succeeding a shower of rain.” 
I have myself seen the plant in the same habitat, and likewise in various parts of England 
and Scotland, though it is chiefly confined to hilly or mountainous districts. In Switzerland it is 
very abundant; yet it was only on the Grimsel, in the autumn of 1814, that I ever saw the capsules 
exserted upon growing plants.
