may be reciprocally grafted on the white beam tree. When plants are to be 
raised from seed, the seeds should be sown as soon as the fruit is ripe; other- 
wise, if kept till spring, and then sown, they will not come up till the spring 
following. When it is inconvenient to sow them immediately that they are 
gathered, they may be mixed with soil, and treated like haws (see Pyrus aucu- 
paria); and, if sown in the March following, they will come up the same 
season. The varieties may be propagated by cuttings, or by layering; but 
they root, by both modes, with great difficulty. Layers require to be made of 
the young wood, and to remain attached to the stool for two years. 
Statistics. Yn the environs of London, the largest tree is at Syon, and is 40 ft. high, with a trunk 
2ft. in diameter, and the diameter of the head 42 ft _; one at Kew is 25 ft. high ; in Oxfordshire, in 
the Oxford Botanic Garden, one, 30 years planted, is 25ft. high, the diameter of the trunk 16in., 
and of the head 17 ft. ; in Yorkshire, at Hackness, 25 years plentes and 28 ft. high. In Scotland, 
in the environs of Edinburgh, at Hopetoun House, 18 years planted, and 20 ft. high a4 Perthshire, 
in the Perth Nursery, 40 years planted, and 32 ft. high, the diameter of the trunk 17 in., and of the 
head 22ft. In Ireland, in Dublin, at the Glasnevin Botanic Garden, 35 years planted, and 30 ft. 
high, the trunk 12in. in diameter, and the head 19 ft. In Sweden, in the Botanic Garden at Lund, 
it is 46 ft. high.

Leaves oblong, wedge-shaped at

Description, §c. These trees bear so 
close a resemblance to P. A‘ria, as to leave 
no doubt in our minds that they are only 
varieties and subvarieties of that species. 
They are found in a wild state in France, 
Germany, and Sweden; and perhaps also 
in the Highlands of Scotland, where, ac- 
cording to Sir W. J. Hooker, P. A‘ria 
varies in having the leaves more or less 
cut at the margin. They are all well de- 
serving of culture.

to 30 ft. high, a native of Nepal and Kamaon, introduced in 1820. This 
tree is remarkable for the rapidity of its growth, its long broad leaves, and 
their woolly whiteness ; and also for being one of the very latest trees, 
whether foreign or indigenous, in coming into leaf; being later than either 
the mulberry or ash. The leaves are conspicuous, on their first expansion,
