ARBORETUM ET FRUTICETUM BRITANNICUM.
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, for their
whiteness, particularly underneath ; and in autumn, before they drop oft? for
tlieir fine yellow colour.

A deciduous tree. Britain in woods, and throughout tlie Middle and
North of Europe, and Western Asia. Height 40 ft. to 50 ft. Flowers white ;
May and June. Fruit red ; ripe in November. Decaying leaves yellowish
brown. Naked young wood purplish, marked with white spots.
The leave,s, which are on long footstalks, are cut into many acute angles,
like those of some species of maple. They are nearly 4 in. long, and 3 in.
broad in the middle, bright green above, and slightly woolly imderneath.
The flowers are produced in large bunches at tho end of the branches; and
they are succeeded by roundish compressed fruit, not unlike common haws,
but larger, and of a brown colour when ripe. The tree is of slow growth,
and in this respect, and most others, it resembles P. yj'ria ; but it is less
' The wood resembles that of P. A'ria, but is without its peculiarly
g smell. It weighs, when newly cut, 63 lb. to the cubic foot, and when
XXVI. Jîo sa 'c eæ : p y ' r u s . 4 3 7
dried, 48 lb. 8 oz. It is employed for all the different purposes to which tliat
of P. d'ria is applicable, and is considered rather preferable as fuel, and for
charcoal. The fruit is brought to market both in England and France ; and,
when iu a state of incipient decay, it eats somewhat like that of a medlar.
As an oniainental tree, it.s large green buds strongly recommend it in the
winter time, as its fine large-lobed leaves do in the summer, and its large and
numerous clusters of rich brown fruit do in autumn. It will grow in a soil
not poorer, but more tenacious and moist, than what is suitable for P. zJ'ria ;
anti it requires a slieltered situation. It seems more liable to the attacks of
insects than that species, and does not thrive so well in the neighbourhood of
London. It is propagated exactly in the .same manner as P. vl'ria. There
being no varieties, it does not require to be continued by grafting.
