Excursio)i of the Scottish Alpine Botanical Club. 209 



ning our walk, we found Malva moschata, and on our way up 

 the hill gathered abundance of Polypodium Robertianum. 



Farlton Knot is a hill of a very peculiar formation of 

 limestone, the stone lying in wavy beds, and forming very 

 deep fissures, in which many good plants were found. 

 Near the top was abundance of Ncphrodium rigidum ; 

 its rigid form and characteristic green colour making it a 

 conspicuous object even in the distance. We found also 

 quantities of Scolopendrium vidgare growing in the deep 

 fissures of the limestone rocks, some of the specimens being 

 very fine, also Asperida cynanchica and Carlina vulgaris. 



As we passed along the rocks we found the following rare 

 plants :—^?'e%ana verna, Geranium Robertianum (white), 

 G. lucidum, Sedum aiiglicum, Sanicida europcea, Epipactis 

 latifolia var. viridans and var, rubiginosa^ Listera cordata, 

 Paris quadrifolia, Convallaria majalis, Polygonatum offici- 

 nale, Ai'um maculatum, Aspleniwn Ruta-muraria, Ti-icho- 

 manes, and viride, Aspidium aculeatum, Nephrodium 

 Oreopteris, and Polypodium Dryopteris. 



We also collected in this excursion Tamus communis, 

 Plantago media, and Campanula latifolia. 



We reached our hotel in good time for dinner, all highly 

 delighted with the success of our excursion, but regretting 

 much that we had such a short time to explore this very 

 rich botanical region. 



On Saturday, 2nd August, three of the members returned 

 to Edinburgh; but Mr Boyd, Mr Paul, and Mr Evans pro- 

 ceeded to the Lake District, to explore the botany of that 

 most delightful region. 



Mr Evans kindly furnished me with a list of the principal 

 plants collected.

Although the instances of so-called parasitism among 

 algse are probably for the most part nothing more than 

 simpler cases of epiphytic association between different
