On old and shape up trees , the bark is covered with a dark-coloured lichen , which gives the organic structure a black appearance The aspen has a very characteristic branching pattern which is most overt in winter when the tree is leafless , and in mature trees the topmost branches are o ften bent over horizontallyThe leaves are round and legal community around 2 .5 and 6 cm across , and have irregular blunt teething on their margins . On unripened trees , the leaves are usually lengthened and triangular in shape . The aspen leaf stalks , or petioles , are flattened , which on other trees are round in cross-section , and very pliable near the leaf leaf blade .
