 Denizen. Woods, hedges. Common. Tree. April-June. 

 First record. Grows in Lower Farm Close, Blewbury, Hampstead 

 Norris, and many other places, Mr. J. Lousley, in Russell's Cat. 

 1839. 



The Sycamore occurs so frequently as a planted tree throughout the 

 county that it is needless to give special localities ; there are trees 

 Avithin the Abbey ruins at Beading ; its leaves are often infected by 

 Rhytisma acerinum. 



It readily propagates itself by its seeds, and seedlings with 2-4 

 cotyledonary leaves are often to be seen. It is now thoroughly 

 established, and in some cases, as on Pinkney's Heath, Wytham, 

 Bagley Wood, Tilehurst, &c., looks quite wild. 



A fine specimen is to be seen in Hampstead Marshall Park.

First record. Acutie foliorum cognitu facilis Aceris species quam 

 prope Oxoniam oriri nonnulli sponte nobis asseruerunt, Lobel. 

 Adversaria, 443, 1570. (With the above notice Lobel figures a por- 

 tion of the tree, which shows the leaves to be much more deeply 

 cut than in the common pla^jt. Lobel says that it had been mis- 

 taken for the Plane. The above record is given by Mr. W. A. 

 Clarke as the first notice of the occurrence of the Maple in 

 Britain. Lobelius' description does not appear to point with 

 certa,int J to A. campestre.) Acer campestre, common in hedges, and 

 the wood is much valued for turning in the lathe, Mavor's Agr. 

 Berks, 1809. Veiy common about Hampstead Norris, &c., Mr. J. 

 Lousley in Russell's Cat. 1839. In Phaenogamous Botany, 1835, Baxter 

 describes the samaras as being downy, and says that Erysiphe 

 hicornis \_uncinula] is common on the leaves about Oxford. 

 Acer campestre is a very frequent plant in our hedges, especially on 



the Oolite, Chalk, and dry gravelly soils ; it is generally distributed 



through the county, and adds much to the beauty of the country lanes 



by its autumnal colouring. There is a fine tree between thirty and 



forty feet high near Kintbury. 



Var. HEBECARPTTM, DC, Prod. i. 594. A. campestre, Linn. Herb., is 



the common and generally distributed form. It has pubescent samaras. 



Specimens were sent to Bot. Exch. Club in 1892 by the author from 



Hinksey.
