water to extract some of its bitterness, and then boiled with 

 sugar, makes a kind of jelly, which is tolerably flavoured. A 

 spirit is also reported by Lightfoot to be distilled from these 

 berries. Birds of the Thrush kind devour them with avidity ; 

 and our Mountain Ash trees, planted for ornament in most 

 parts of England, are thus unfortunately stripped, early in au- 

 tumn, of their produce.

 the north end of the isle of Arran. Mr. J. Muckaij. 



Tree. May. 



A moderate-sized tree, with smooth grey branches, hoary when 

 young. iert«;es alternate, crowded about the extremities, stalked, 

 oblong, acute, serrated, lobed, and towards the base often deeply 

 pinnatifid ; smooth above ; white and finely cottony beneath. 

 Stipulas smooth, awl-shaped, attached to the footstalks, but deci- 

 duous. Fl. cymose, cream-coloured, much like those of the last, 

 or rather of the following, species, StijlesS or 4, and the cells of 

 the fruit, which are soft and jDliant like those of the Mountain 

 Ash, agree with them in number. Whether this be a mere va- 

 riety of the P. Aria hereafter described, or, as Linnseus tliought, 

 a mule between that tree and the Mountain Ash, it is regularly 

 propagated by seed, and a frequent decoration of modern gar- 

 dens and shrubberies. A decided variety of P. Aria, slightly 

 pinnatifid, growing on Castle Dinas y bran, was taken by Mr. 

 Hudson for the Linncean Sorbus hybrida. Dr. Pratinton has 

 sent me this from the original spot, and it obviously connects 

 the plant before us with the following ; see P. Aria /3.

 neath. Flowers corymbose. Styles about two.
