cenujinosus. HoLkirk, iu his second edition, uses the 

 name Ditriclium glaucesccns. In Berkeley's Handbook it 

 is found as Lcptotviclium glaucesccns. Finally, Braithwaite 

 calls it Saclania ccesia, following Lindberg, and remarks, 

 curiously enough, in the face of all this variety of nomen- 

 clature, that " it is a good example of a truly natural 

 genus." It is to be hoped that, after the completion of 

 Dr. Braithwaite's valuable Moss-Flora, a greater degree of 

 order will be introduced into this baffling confusion. 



As we proceeded along the base of the rocks, nothing of 

 special importance was found, so Mr. Gunn and I climbed 

 up the face of the clifts out on to the table-laud above in 

 search of Carcx rarijlora, Sm., which, however, we did not 

 light upon. In the midst of a very large bed of Scirpus 

 cccspitosus, Linn., occurred a patch of considerable size, 

 which presented a remarkable appearance. On the summit 

 of every stem, in place of the usual flower head, was what 

 had the appearance of a small delicate egg-shaped fruit, 

 like a miniature plum, of a bluish-brown colour, very 

 smooth and regular in shape, and conspicuous enough to 

 be observable some yards oft". I gathered specimens, and 

 submitted them to Professor Trail of Aberdeen, who was 

 of opinion that the fungus was probably Ustilago car ids, 

 and stated that he had not before met with an Ustilago on 

 that plant. Eejoining the members of the party we had 

 left below, who had found a certain number of the Alpine 

 plants that were to be expected in that locality, we at 

 length brought a delightful day to an end. 



The chief plants found were these : — Draba incana, 

 Linn. ; Silenc acaulis, Linn. ; Oxytropis campcstris, D.C. ; 

 Saxifraga oppositifolia, Linn. : S. nivalis, Linn. ; S. stellar is, 

 Linn. ; *S^. aizoiclcs, Linn. ; Saussurea alpina, D.C. ; Arcto- 

 staphylos ?7r«-f/?--52, Spreng. ; Tricrdalis eurojKca, Linn. ; Salix 

 myrsinites, Linn. ; Carcx capillaris, Linn., etc. ; Crypto- 

 gramme crispa, E. Br. ; Asplcnium viridc, Huds. ; A. 

 irichomanes, Linn. ; Polystichum aculcatum, Syme ; P. var. 

 lohatum, Presl. ; P. lonchitis, Eoth. ; Zastraa oreoptcris, 

 Presl. ; Lycopoclium Sclago, Linn.; L. cumotimim, Linn.; 

 Z, alpinum, Linn. ; Selaginclla selaginoides, Gray. 



Wednesday, 12th July, did not promise well, being 

 cloudy and foggy. We drove up to Acharn, and found
