174 2 The Trees of Great Britain and Ireland 



Distribution 



C. oxyacantha is widely spread throughout Europe, occupying nearly the same 

 territory as C. monogyna, but being much less common. Willkomm believes it to be 

 more prevalent in the north than in the south of Europe. In France, according 

 to Mathieu, it does not grow in the region of the olive ; while elsewhere it is 

 comparatively rare, and scarcely ever attains the dimensions of a tree. I saw it in 

 191 2 in the interior of the Forest of Orleans, forming a large shrub, and growing in 

 shade, as it does in the Gamlingay Wood, near Cambridge. 



It is doubtfully wild in Scotland and Ireland; and is apparently indigenous 

 only in the midland, eastern, and south-eastern counties of England. It is recorded 

 for many stations in Kent, Surrey, Middlesex, Oxfordshire, and Cambridgeshire. 

 It is not mentioned as a native plant for the northern or western counties in any 

 of the published floras in which the two species are distinguished. In England, as 

 far as we know, it is usually a shrub ; and we have no records of any large trees 

 of this species. (A. H.)
