The genus Euphrasia has been the subject of our special atten- 

 tion during our excursion and I have therefore had a very rich 

 material at my disposal; besides these newly gathered specimens 

 there are some smaller and badly preserved ones in the collection 

 of the Botanical Gardens determined by Prof. Wettstein. 



In working up this subject I have made use of Wettstein: 

 Monographie der Gattung Euphrasia, 1896, and F. Townsend: 

 Monograph of the British Species of Euphrasia, Journ. of Botany 

 1897; but it must be admitted that several of the species have 

 appeared to me to be hardly distinct and it was even necessary 

 to draw an arbitrary and unnatural line to distinguish them from 

 each other. Thus E. latifolia merges on the one band into E. atro- 

 piirpiirea (— E. fonlaensis) and on the other into E. ciirta; and E. 

 scotica is difficult to distinguish from E. gracilis, whilst it also 

 tends towards E. atropurpurea. In the meantime I have done my 

 best to distinguish them from each other and the follovs'ing is a list 

 of them: 



44. E. atropurpurea (Rostr.) Ostenf. mscr. ; Syn. E. gracilis, L atro- 

 purpurea Rostr. Fær. FL, 1870, p. 48 (vidi specimina originaha); Syn. 

 E. foulaensis Towns., Wettst. 1. c. pp. 139 and 299, Towns. 1. c. p. 422. 



Found here and there on all the Islands, but not in the lowlands, 

 generally grows in the hills on grassy rock-ledges, from 300 m. up- 

 wards.
