In addition to the results of my own field-work. I have 

 had the opportunity of examining some rich gatherings 

 of cryptogamic plants made by Mr. Win. West, F.L.S., in 

 Arran, in August 1910. This material, on examination, 

 has yielded a considerable number of interesting species 

 additional to those noted by me ; and Mr. West has kindly 

 permitted me to include particulars of them in this paper. 



The phaenogamous plants of the island are tolerably 

 well known, and. accordingly, I propose to limit my notes 

 principally to the more critical species of flowering-plants 

 observed, but shall also mention a few plants which seem 

 to be of local occurrence in the island. 



As the Hepaticae have been listed by Mr. Symers M. 

 Macvicar. 1 I need only mention some of the less common 

 species observed, and a few which appear to be hitherto 

 unrecorded for the island. So far as the mosses are con- 

 cerned, I do not propose to mention all the species observed, 

 but shall confine my list mainly to such species as are not 

 given for v.c. 100 (Clyde Isles) in the •'Census Cata- 

 logue " of the Moss Exchange Club. An asterisk denotes 

 species or varieties not given for v.c. 100 in the " Census 

 Catalogue." or in Mr. Macvicar's " List." 



My sincere thanks are tendered to the following botanists, 

 namelv Charles Bailey. M.Sc. F.L.S. : Arthur Bennett. 

 A.L.sf: E. Drabble, D.Sc. : G. C. Druce, M.A.. F.L.S. ; Rev. 

 E. S. Marshall, F.L.S. : and Rev. W. Movie Rogers, F.L.S.. 

 for help with the flowering plants : and in connection with 

 the bryophyta. lam much indebted to Mr. Wm. West. F.L.S.. 

 for placing his gatherings at my disposal, and to Mr. J. A. 

 Wheldon, F.L.S., for his aid in determining the Sphagna, 

 and checking my identifications in some doubtful cases. 



Ranunculus acris, Linn., var. Natharstii (BerlA "V\ hat 

 is probably this plant occurs at the top of a steep gully, 

 immediately below Cir Vhor, on the saddle between Glen 

 Rosa and Glen Sannox. The plants I gathered were 6 to 7 

 inches high, with conspicuously large flowers. The fruit 

 in my specimens is rather immature, but even in that state 

 the carpels have a strongly hooked beak. Mr. Druce thinks 

 the determination is probably correct. My specimens agree
