EDWARD SHEAIIBURX MARSIfALL 11 



National Herbarium or at the Linneaii Society for tlie consultation 

 and com])arison of books and specimens necessary for his work. In 

 everything connected witli liis herbarium — as, indeed, in other respects 

 — Marshall was exceeding'ly methodical: the ample space of the 

 llectory enabled him to devote a room to the accommodation of his 

 plants and books, and things not dealt with at once were carefully 

 endorsed — e. g. some papers which I had sent him for notice came 

 back to me after his death labelled " Important : for review in J. of. 

 E. after settHng at Off as Dyke." 



This tribute to Marshall's memory has run to greater length than 

 I had anticipated, but I do not think that those who knew him, 

 either personally or by correspondence, will consider it too long : 

 rather will they note omissions which they would have been able and 

 willing to supply. By his death, the Editor has lost a valued friend 

 and the Journal a principal contributor, and this memoir may fittingly 

 conclude with a reference to the assistance rendered by Marshall to 

 both at a critical period. It will be remembered that owing to the 

 War and other circumstances a serious deficit was experienced at the 

 end of 1916. By the generosity of friends and in response to a 

 circular signed by five leading British botanists, the deficit was made 

 lip, as stated in the volume for 1917, p. 148 ; but it could not then 

 be said that the circulation of the appeal, the receipt and acknow- 

 ledgement of subscriptions, and other incidental trouble was entirely 

 undertaken by Marshall, who was also, with his wife, the most liberal 

 subscriber.

LLANBEBIS LICHENS. 

 By J. A. Wheldojs^. 



The following list was compiled in the district around Llanberis 

 between the 3rd and the 8th of August. In company with the Misses 

 Armitage and Cobbe, and Messrs. Druce, Jones, Ehodes and Travis, 

 a considerable proj^ortion of that time was devoted to the examina- 

 tion of the Phanerogams and Br3^ophyta of the vicinit3\ Two days 

 were somewhat spoiled by unfavourable weather. The list cannot, 

 therefore, be regarded as an exhaustive one, and many of the lichens 

 know^n to occur in the district were not seen at all. Others, such as 

 Cerania vermicularis, Avere unexpected, because not recorded in the 

 Flora of Carnarvonsliire or Leighton's British Lichens, and it is 

 singular that so conspicuous a species, occurring close by the jDath 

 from Llanberis to the Snowdon summit in some abundance, should 

 have been overlooked. The comparatively few corticole species in- 

 cluded, is due to the fact that most of our time was spent on the 

 hills, above the tree zone, and not to any povert}^ of species in 

 this group. The armngement is that of A. Lorrain Smith's Briiish
