CONTEIBUTIONS TO THE COKNISH FLORA.

credited six new plants to the district, and this season, as the 

 lists appearing in this paper show, sixteen more have appeared. 



The discovery of a colony of Nasturtium palustre at 

 Lostwithiel restores a vanished plant to our flora. In 1835 it 

 was recorded from the banks of the Lynher, near St. Germans,* 

 but when Briggs published his Flora of Fltjmouth, in 1880, it 

 was registered "extinct." In Dr. Ealfs' MSS. Flora of West 

 Cornwall] there is the following entry : — " Formerly grew on the 

 wall of the basin at Copperhouse, but the wall has been repaired 

 and the plant destroyed." Mr. Tellam once found the plant on 

 a ballast heap at Par, and it has been recorded for the Scilly 

 Isles,:]: but in both places it made but a short stay. 



Arenaria verna, at one time thought not to occur in Cornwall 

 off the serpentine district, has been discovered in two distant 

 parts of the county, the St. Minver locality constituting a new 

 vice-county record. Similarly, the distribution of Juncus pygmaeus 

 has been extended ten or twelve miles by being found on the 

 borders of the Loe Pool. Further, a comparison of the following 

 list, with the list given above of plants new to the county, will 

 show that three new Docks, three Pondweeds, and four Sedges 

 are contributed to the Lizard flora. The only previous record for 

 Cnicus eriophorus is 105 years old, Truro being quoted as a Cornish 

 station by Withering. § Hitherto FihicMa umhellata, one of the 

 rarest of British grasses, has kept to the one place in Cornwall 

 where it was discovered nearly 215 years ago, viz.: between 

 Penzance and Marazion, just opposite G-ulval church.
