 British Eubi."). Truro to Peuryn, rev. F. A. Rogers, teste

R. anglosaxonicus, Gelert, subsp. curvidens, A. Ley. 

 Specimens found at Castle-hill, Falmouth, by the rei\ F. A. Rogers, 

 are labelled "apparently a form of this," by the rev. W. Moyle 

 Eog'ers. 



R. rosaceus, W. (Jc N., subsp. Powellii, Eogers. Found 

 by 2Ir. Bruce m a moor west of Truro. It is abundant in the 

 more elevated parts of Epj)ing- Forest, and is also found in west 

 Kent and Oxfordshire. Its discovery in Cornwall is a curious 

 side-light on plant geography.

Potentilla norvegica, Linn. In June I found this plant 

 in rather sparing numbers aroiind Par Harbour. From all other 

 British species of this genus it may be distingiashed by its 

 trifoliate radical leaves and numerous small yellow flowers, 

 rather crowded at the top of the plant. Although of quite 

 modern introduction into the country, it has thoroughly 

 established itself in Yorkshire, Middlesex, Cambridgeshire, 

 Hertfordshire, York, and few other counties. Its attempt to find 

 a permanent place on Cornish soil will be watched with interest. 



Salicornia striata, Dumort. Specimens of the glasswort 

 gathered by I)r. Vigurs at the Gannel, Newquay, and submitted 

 to two specialists, have been referred to this species. 



S. ramossisima, Woods. Dr. Vigurs has also collected this 

 at the Gannel. 



Observation on the genus Salicornia. No British county 

 has had its glassworts more sadly neglected than Cornwall, and 

 until A-ery recently in no county had anything like justice been 

 done them. Most botanists have been aware of the existence of 

 forms Avliich do not answer to the accepted diagnosis of 

 S. hcrhacea, Linn, but the literature of the subject has been too 

 indetinite and scattered to allure many stiidents to a thorough 

 local investigation of the genus. Another great drawback has 

 been in the plants themselves. For the most part, if carefully
