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

The principal centres for beechwood furniture in England are at High Wycombe,<br />

and Newport Pagnell in Bucks, and <strong>the</strong> price <strong>of</strong> clean trunks in <strong>the</strong>se districts is<br />

from is. to is. 6d. per cube foot standing, according to <strong>the</strong> situation. Beechwood is<br />

also used largely for making saddle-<strong>trees</strong>, and in consequence <strong>of</strong> <strong>the</strong> <strong>great</strong> demand<br />

for <strong>the</strong>se during <strong>the</strong> South African war, went up to a very high price in 1901, when<br />

I was <strong>of</strong>fered is. 4d. a foot standing for beech <strong>trees</strong> which in ordinary times would<br />

not be worth more than 8d. or gd. a foot. Being easy to split it is, where <strong>the</strong>re is a<br />

demand for firewood, easier to dispose <strong>of</strong> <strong>the</strong> branches and rough parts <strong>of</strong> <strong>the</strong> tree<br />

for this purpose, but <strong>the</strong> amount <strong>of</strong> waste is much <strong>great</strong>er in <strong>the</strong> beech than in<br />

some o<strong>the</strong>r <strong>trees</strong>, unless grown in thick woods. For more minute particulars <strong>of</strong> <strong>the</strong><br />

characters and uses <strong>of</strong> this timber, Stone's Timbers <strong>of</strong> Commerce, p. 231, and<br />

Loudon, pp. 1959-64, may be consulted with advantage. (H. J. E.)<br />

AILANTHUS<br />

Ailanthus, Desfontaines, Mem. Acad. Paris, 1 786 (1789), 263, t. 8 ; Bentham et Hooker, Gen. PI. i .<br />

309 (1862); Prain, Indian Forester, xxviii. 131, Plates i. ii. iii. (1902).<br />

LOFTY <strong>trees</strong> with very large alternate imparipinnate leaves. Flowers small,<br />

polygamous, bracteolate, in panicles. Calyx 5-too<strong>the</strong>d, imbricate. Petals 5, valvate,<br />

disk lolobed. Stamens 10 in <strong>the</strong> staminate flowers, 2-3 in <strong>the</strong> hermaphrodite<br />

flowers, and absent in <strong>the</strong> pistillate flowers. Ovary present in pistillate and<br />

hermaphrodite flowers, rudimentary in staminate flowers, deeply 2-5 cleft with<br />

connate styles: ovules i in each cell. Fruit <strong>of</strong> 1-5 samaras, with large mem<br />

branous wings, each samara containing i seed.<br />

Ailanthus belongs to <strong>the</strong> Natural order Simarubese, and consists <strong>of</strong> about eleven<br />

species occurring in India, Indo-China, China, Java, Moluccas, and Queensland.<br />

Most <strong>of</strong> <strong>the</strong> species are tropical <strong>trees</strong>, Ailanthus glandulosa being until lately <strong>the</strong> only<br />

species which was known to occur in temperate regions; but A ilanthus Vilmoriana,<br />

Dode, 1 must be here mentioned. This is a tree remarkable for its prickly branchlets,<br />

<strong>of</strong> which only one specimen is known, namely, a young, healthy, vigorous tree<br />

grown in M. de Vilmorin's garden at Les Barres. 2 It was raised from seed sent by<br />

Pere Farges in 1897 from <strong>the</strong> mountains <strong>of</strong> Szechuan in Central China; 3 and<br />

is certainly a very distinct species. I saw it in <strong>the</strong> summer <strong>of</strong> 1904, and in<br />

general aspect <strong>the</strong>re is little to distinguish it from <strong>the</strong> common species. It is now<br />

about 20 feet in height. The leaflets in this species are less abruptly acuminate,<br />

not falcate, much duller above and paler beneath, with larger glands than in Ailanthus<br />

glandulosa. All <strong>the</strong> parts <strong>of</strong> <strong>the</strong> tree are much more pubescent than in that species.<br />

Ailanthusgrandis* Prain, a new species from Sikkim and Assam, which attains<br />

120 feet high, may be here mentioned, as it is possible that it might be grown in<br />

Cornwall or in Kerry. It has not yet been introduced.<br />

1 Revue Horlicole, 1 904, p. 445, fig. 184.<br />

2 Figured in Fruticetum Vilmoriniamtm, 1 904, p. 31 ; where it is called Ailanthus glandulosa, var. spinosa.<br />

3 Mr. E. II. Wilson informs us thai it is very common in <strong>the</strong> valleys <strong>of</strong> <strong>the</strong> Min, Tung, and Fou rivers, between 2000<br />

and 4500 feet. He says that it is much more spiny in <strong>the</strong> young than in <strong>the</strong> adult state, and that it has much larger foliage<br />

than <strong>the</strong> common species. A plant is now growing at Kc\v, and is referred to by Mr. Bean in Gardeners' Chronicle, xxxviii.<br />

276(1905).<br />
