3. THE EYEBRIGHTS OF CORNWALL. 



Arranged as it was in accordance witlt tlie order observed in 

 the ninth edition f)f the "London ('atah)gue," my "Tentative 

 List " takes cognizance of one species of eyeln'ight only, the 

 varieties and forms then known to occur in tlie county being 

 grouped under the okl aggregate Euphrasia officinal ix, Linn. In 

 1897, just two years after the publication of the last edition of 

 the " London Catalogue," Mr. F. Townsend summai-ized his 

 almost life-long critical labours on the genus in the form of an 

 illuminating Monograph of British forms, which appeared in the 

 pages of the "Journal of Botany." That event marked an 

 epoch in the de\'elopment of our knowledge of British eye- 

 brights. With a workable account of tlu^ genus at their service, 

 many botanists have been induced to take uj) the study, and 

 slowly but surely order is coming out of long-standing confusion. 

 The late Dr. Ralfs made a brave attempt to unravel the 

 eyebrights of West (Jornwall, and in this direction he may be 

 regarded as something of a pioneer ; but he was an old man when 

 he embarked on the study, and the master-hand had lost much 

 of its cunning. More recently Dr. Vigurs has applied his mind 

 to the subject, and with that desire for accuracy which I have 

 always been able to associate with his \\ork he has, either per- 

 sonally, or through Mr. A. 0. Hume, obtained the opinion of Mr. 

 Townsend on the whole of his gatherings. His records therefore 

 may be accepted as })eing as accurate as our present knowledge 

 of the subject will allow us to claim accuracy. Here, as in 

 sevei'al other connections, I wish to record my indebtedness to 

 Dr. Vigurs for his unstinted assistance and \'aluable advice. 



So as to bring our knowledge of the Cornish forms of the 

 genus up to date, I have incorporated the records appearing in 

 my " Tentative List " with those handed to nu^ by Dr. A'igurs 

 and the rev. W. Moyle Rogers. With the number of l)otaiiists 

 now at work in Ccrnwall, the list should be considerably 

 augmented next year.
