CONTRIBITTIONS TO THE CORNISH FLORA. 131 



through Cornwall in 1662, and we find him chronicling it for 

 "the gravelly- shore between Pensans and S. Michael's Mount" 

 in his Catalogus Plantarum Anglm, 1670. How long it continued 

 in occupation of the place is uncertain, but we do know that it 

 had disappeared soon after the birth of the last century, if not 

 before, for the authors of the Botanisfs Guide^ 1805, raake no 

 mention of it, and in his Botanical Tour, 1820, Jones tells us he could 

 get no information concerning it. In 1881, like a voice from the 

 past, a single plant sprang up at Pra Sands, and was duly placed 

 on record in the "Transactions" of the Penzance Natural 

 History and Antiquarian Society, 1884, by Dr. Ealfs. 



Corrigiola littoraUs, Linn., the recent disappearance of which 

 from the Loe Pool comes as a great grief to Cornish botanists, is 

 first noticed in the Botanist'' s Guide. Until 1897 it maintained its 

 ground in varying numbers from year to year, but owing to the 

 raising of the outlet of the Pool the shelving rocks, where the 

 little rarity abounded, are now covered with water, and it is to 

 be feared that we may not see the plant there again. In all 

 probability Mr. J. D. Enys was the last person to find it. 



Eupliorhia Peplis, Linn. Most of the extinctions, it will be 

 observed, were one-station species. The one now under notice 

 grew in several. Merrett knew it between Penzance and Marazion 

 in 1666, and the last record for it there is in the Phytologist, 1851. 

 In T. Q. Couch's "Addenda" to the Flora of Polperro, in the 

 Eoyal Cornwall Polytechnic Society's Report, 1849, Mr, C. Peach 

 is quoted as the authority for it at " Lantick Bay, in abundance 

 on some parts of the beach." It has long since disappeared from 

 that place, and owing to the action of the sea the habitat itself 

 has been destroyed. Whitsand Bay, near the Eame, was another 

 stronghold, but no one has seen it there since 1847, when Mr. 

 F. P. Pascoe found a solitary plant, and announced the fact in 

 the Phytologist of the same year. In 1852, a Mr. J. Wood, in a 

 letter to Dr. Ealfs, which afterwards appeared in the Penzance 

 Natural History and Antiquarian Society's "Transactions," 

 claimed to have gathered the plant on the Scilly Isles, but Dr. 

 Ealfs was never able to verify the record. 



JJrtica piluUfera, Linn., is both a one-locality and a one-record 

 plant. In Borlase's Natural Sistory of CormoaU, 1758, it is said
