The True Service (Pyrus sorbus) closely resembles the Mountain Ash in habit and foliage, but it is not a native of Britain, though it used to be claimed as such, on account of its growing in the more mountainous parts of Cornwall and in Wyre Forest, Worcestershire. The latter, however, is the only Service tree that could put in such a claim, for it grows—or grew?—far from habitations or cultivated land, and the presumption is that it has not owed its introduction to man. Still, "one swallow does not make a summer," and a solitary wild tree does not give the species a title to be reckoned as British. It is occasionally cultivated here, and its portrait, with a brief account of its points of difference from the Mountain Ash, may be useful. A comparison of the photographs from the boles of the two species will show a great difference: that of the Mountain Ash being smooth, whilst that of the Service is rugged. The leaf is similarly broken up into paired leaflets, but these are broader, and are downy on both upper and lower sides. The white flowers are as large as May-blossoms, and the fruits, which may be either apple-shaped or pear-shaped, are greenish-brown, with rusty specks, and four times the size of Rowan-berries. In winter, when there are neither leaves, flowers, nor fruits to help in the distinction, the bark may be taken in conjunction with the leaf-buds, which are green and smooth in this species, whilst those of the Mountain Ash are black and downy. The fruit may be eaten after it has begun to decay, as in the case of the Medlar.
