| A series of small burrs scattered over the main trunk which appear as small groups of closely packed buds on machined faces giving rise to the figure known as 'cat's paw', a condition which is most often seen on European oak, Quercus robur. |
| 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. |
