ALIEN PLANTS NEAR EDINBURGH 113 



and Lepidinm Draba, L., are common and apparently established 

 in old quarries, on railway embankments, etc., throughout the county 

 of Edinburgh. 



Claytonia perfoliata^ Donn, is a recurring and troublesome weed 

 in nurseries to the north of the city. 



Petasites fragrans^ Presl, has established itself for half a dozen 

 yards by the side of a burn at Polton ; it is evidently a garden 

 outcast. 



Mercurialis annua, L., one small but perfectly developed plant 

 was found at Burntisland, Fife, in July 1902. 



Polypogon monspeliensis, Desf., was gathered in Leith Docks 

 district in 1902, and also in 1903. 



Poa palustris, L. (P. ferti/is, Host), is common throughout the 

 Leith district, and at Slateford Railway Station. 



Demazeria loliacea, Nyman, is by no means an alien, but it may 

 be interesting to record that the only locality in the county of 

 Edinburgh, where it was plentiful in July 1903 is now beneath a 

 huge railway embankment. 



Poa Chaixii, Vill., in small quantity, was gathered on the border 

 of some pasture land on the slopes of the Pentlands. 



\Festuca sylvatica, Vill., often confounded with the above, but 

 very distinct, is plentiful and luxuriant in a limited area in Roslin 

 Glen. This is the only spot in the county where its presence is 

 known.] 



Apera Spica-venti, Beauv., was seen in each of the five localities 

 above mentioned, and in several others. 



Trifolium hybridum, L., besides the common type, one luxuriant 

 plant was seen in the Leith district, having numerous globular heads, 

 with abortive petals, and barren. 



I am indebted for much assistance in preparing the above 

 list to two fellow-members of the Edinburgh Naturalists' 

 Field Club, Mr. Alistair Murray x and Mr. James M'Andrew. 

 Through the instrumentality of the latter a number of the 

 grasses were named for me by Professor Hackel, and of the 

 other plants by Mr. Arthur Bennet, to both of whom I beg 

 respectfully to tender my thanks. I am also greatly in- 

 debted to Professor Balfour, Regius Keeper of the Edinburgh 

 Botanic Gardens, where through his courtesy and kindness 

 many of the plants were named, and every facility was 

 granted for comparing my specimens with those in the 

 Herbarium. My thanks are also due to Mr. Arthur Smith, 

 Grimsby, who very kindly named and verified a number. 



1 Died 6th February 1904, to the deep regret of a wide circle of friends.
