REPORT ON EXCURSIONS, 1887. 327 



Poa spp. — In very poor condition, owing to the 

 drought. 



Festuca barbata, Haeck. — A good deal of this grass 

 seen. 



Woodsia hyperborea, R. Br. — This plant, which grows on 

 moist rock ledges or crevices in exposed situations, 

 was in a very pitiful state. All its haunts were 

 so dry that I hardly thought it worth while to 

 go to look for it ; but as two gentlemen of our 

 party were very anxious to get plants, I went 

 on their account. As I did not take time to 

 work the rocks on which it grows, I cannot 

 say whether it is holding its place or not. I 

 saw none of it on Ben Lawers, and, in fact, 

 never did. 



CystoiDteris montana, Bernh. — As plentiful as ever on 

 Ben Lawers, but does not appear to be coming 

 out of the inaccessible crevices. 



JPolystichum Lonchitis, Roth. — This seemed one of 

 very few plants which had thriven during the 

 heat of June. The fronds, in many cases, were 

 very large and well-developed. 



We collected some very fine Mosses and 

 Hepaticae, and these I may show at some future 

 time. 



6. Greenock. 



Route. — From Upper-Greenock Station to Rotten- 

 burn, at the south-western end of Loch Thorn. 



Owing to extremely unfavourable weather, few 

 observations could be made. Living specimens of 

 Acme lineata (Drap.) were obtained; and among the 

 rarer plants seen were Saxifr^aga hypnoides, L., 

 Epilobium angustifoliwin, L., and Asplenium viride, 

 Huds.
