|A 'burr' is an irregular-shaped swelling or excrescence found most often on the lower main trunk, but also on branches and rootstocks of a range of tree species. A burr can take on several forms: it may consist of clusters of expanding slow-growing epicormic buds or be formed from a distinct series of irregular contorted swirls.|
