150 The Trees <strong>of</strong> Great Britain and Ireland<br />

<strong>of</strong> a brown oak chest, made for me by Messrs. Marsh, Cribb, and Co., <strong>of</strong> Leeds.<br />

Mouillefert says it is one <strong>of</strong> <strong>the</strong> hardest and most valuable woods grown in France,<br />

and is especially sought for by engravers, carvers, turners, and gun-makers. It<br />

seems to be difficult both to propagate and to grow, at least in its youth, and Loudon<br />

says that though it may be grafted on <strong>the</strong> pear or <strong>the</strong> mountain ash, it is one <strong>of</strong> <strong>the</strong><br />

most difficult <strong>trees</strong> to graft, and that it will not layer successfully, and that it grows<br />

very slowly from seed, not attaining more than i foot high in four years. Seeds 1<br />

sown in autumn germinate in <strong>the</strong> following spring. The young seedling has two<br />

oval entire-margined cotyledons, and attains about 4 inches in height in <strong>the</strong> first<br />

year's growth. Plants may be had from <strong>the</strong> French nurserymen. Mr. Weale, <strong>of</strong><br />

Liverpool, reports as follows on a sample <strong>of</strong> this wood which I sent him : " The<br />

wood is close and homogeneous in texture, tough, but inclined to be brittle. Rays<br />

on transverse section invisible, and rings only to be distinguished by <strong>the</strong> difference<br />

in colour <strong>of</strong> <strong>the</strong> spring and autumn wood. Harder than whitebeam, seasons well,<br />

without warping or splitting, and with little shrinkage. A reliable wood when<br />

thoroughly dry." (H. J. E.)<br />

A tree, attaining exceptionally a height <strong>of</strong> 80 feet, but more generally only reach<br />

ing 40 or 50 feet. Bark smooth and grey at first, but after fifteen or twenty years <strong>of</strong><br />

age scaling <strong>of</strong>f in thin plates, and ultimately becoming fissured. Leaves long-stalked,<br />

broadly oval, nearly as broad as long, with a cordate or truncate base and an acute<br />

apex ; with 6-10 triangular acuminate serrate lobes ; shining and glabrous above,<br />

obscurely pubescent beneath; nerves pinnate, 5-8 pairs. Flowers white in corymbs.<br />

Styles 2, glabrous, united for <strong>the</strong> <strong>great</strong>er part <strong>of</strong> <strong>the</strong>ir length. Fruit ovoid, brownish<br />

when ripe, with warty lenticels, vinous in taste when in a state <strong>of</strong> incipient decay;<br />

cut across transversely it shows a ring <strong>of</strong> white hardened tissue, forming a mesocarp<br />

around <strong>the</strong> core.<br />

The leaves are generally described as glabrous on <strong>the</strong> under surface, but in all<br />

specimens traces <strong>of</strong> pubescence may be observed, which is much more marked on<br />

coppice shoots and epicormic branches.<br />

VARIETIES<br />

None have been obtained in cultivation so far as we know, and wild <strong>trees</strong> vary<br />

very little in any <strong>of</strong> <strong>the</strong>ir characters. A variety, pinnatifida, with <strong>the</strong> lobing <strong>of</strong> <strong>the</strong><br />

leaves very deep, is described by Boissier, 1 from specimens occurring in Asia<br />

Minor and Roumelia.<br />

IDENTIFICATION<br />

The leaves in summer are unmistakable (see Plate 44), and can only be<br />

confounded with certain forms <strong>of</strong> Pyrus latifolia ; but in <strong>the</strong> latter species <strong>the</strong> under<br />

surface <strong>of</strong> <strong>the</strong> leaf is always plainly grey tomentose, and <strong>the</strong> lobes are much shorter<br />

than in P. torminalis. I n winter <strong>the</strong> following characters, shown in Plate 45, are<br />

available.<br />

Twigs: long shoots, glabrous, shining, somewhat angled, with numerous<br />

lenticels ; leaf-scar semicircular with 3 bundle traces, set parallel to <strong>the</strong> twig on a<br />

greenish cushion. Buds almost globular, terminal larger, side-buds nearly appressed<br />

to <strong>the</strong> twig ; scales green with a narrow brown margin, glabrous, with <strong>the</strong> apex<br />

double-notched. Short shoots slightly ringed, glabrous, ending in a terminal bud.<br />
