OX THE BOTANY OF MALHAM. 



By Louis C. Miall. 



Part IY. — Lichenes. 

 In approaching tliis part of the Botany of Malham, I feel, even 

 more strongly than hitherto, my own incompetence for the task I have 

 undertaken. Indeed, it is only the deshe of rendering the list as complete 

 as possible, which mduces me to include the Lichens at all. The excellent 

 list furnished by Dr. Carrington to the " Flora of the West-Riding " renders 

 the wish feasible, and any one who takes the trouble to compare this list 

 with it will see how largely I am indebted to the work of others. I have 

 added references which will enable the student of the less modern manuals 

 of cryptogamic botany to identify the species here mentioned. The few 

 plants and stations which are distinguished by the mark of verification (!) 

 have been certified by the kindness of various friends to whom I have sent 

 specimens.
