Ixii PROCEEDINGS OF THE 



llTH August, 1885. 



Mr. Peter Ewing in the Chair. 



Mr. D. A. Boyd reported on an excursion made to Langbank 

 on 8th inst., when the members were met by Dr. Marcus Calder, 

 Secretary of the Greenock Natural History Society, who kindly 

 acted as leader. The shore east from Langbank was first 

 visited, and after a turn through the neighbouring woods the 

 party proceeded to Bishopton. The following were among the 

 plants observed: 



Ranunculus sceleratiLS. 

 Cardamine ainara. 

 Stellaria nenwruyn. 

 Spergularia rubra. 

 S. neglecta. 

 S. marginata. 

 Circcea lutetiana. 

 Piinpinella Saxifraga. 

 CEnanthe crocata. 

 Carum verticillaturn. 

 Juncus Gerardi. 

 Zostera marina. 



Ruppia rostellata. 

 Scirpus Taherncemontani. 

 S. inaritiiniLs. 

 Aspleniuin Ruta-niuraria. 

 Dicranuin niajus. 

 Cainpylopus fragilis. 

 C. atrovirens. 

 Ainplioridium Mougeotii. 

 Bartramia pomiformis. 

 B. ithyphylla. 

 Neckera c'rispa. 



Mr. Boyd showed specimens of Ruppia rostellata, Koch., in 

 flower and immature seed, and made some remarks on the 

 characteristics of the plant. It is rare in the West of Scotland, 

 but has been recorded for Dundonald, West Kilbride, Lesser 

 Cumbrae, and Kilcreggan. The old records relate to ** R. 

 maritima, L.," which has been divided by modern botanists 

 into the two species R. spiralis, Hartm., and R. rostellata, 

 Koch; but the former of these does not appear to have yet 

 been found in the South-Western counties. Although occurring 

 in some abundance on the muddy shore of the River Clyde at 

 Langbank, within high-water mark, its presence in the locality 

 seems hitherto to have been overlooked. The plant is not 

 included in Kennedy's Clydesdale Flora.* 



Mr. Boyd also showed a specimen of the fruit of the Horn- 

 beam, Carpinus Betulus, L., from West Kilbride, on which he 

 made some remarks. 



Mr. Peter Ewing gave an account of a visit to Ben Lawers 

 in July, and referred to the state of the vegetation on that 

 mountain this season as contrasted with previous years. 

 Although he had visited Ben Lawers for a good many 

 consecutive summers, he had never found vegetation so much 

 retarded, and this he ascribed to the long-continued easterly 

 winds in spring and early summer. He had met no one who 

 remembered a season in which the snow had lain so long. 

 Among the plants referred to by Mr. Ewing were the 

 following :
