and the wood, which is very hard and susceptible of a fine polish, is
largely used in the making of wedges. It is a rare species in this
country.

P. SINICA (_syn P. sinensis of Lindley_).--Chinese Pear Tree. China and
Cochin China, 1820. Another very ornamental Crab, bearing a great
abundance of rosy-pink or nearly white flowers. It is a shrub-like tree,
reaching a height of 20 feet, and with an upright habit of growth. Bark
of a rich, reddish-brown colour. It is one of the most profuse and
persistent bloomers of the whole family.

P. SINENSIS (_syn Cydonia chinensis_).--Chinese Quince. China, 1818.
This is rarely seen in cultivation, it having, comparatively speaking,
few special merits of recommendation.

P. SMITHII (_syns Mespilis Smithii_ and _M. grandiflora_).--Smith's
Medlar. Caucasus, 1800. The habit of this tree closely resembles that of
a Hawthorn, and although the flowers are only half the size of those of
the Common Medlar, they are produced in greater profusion, so that the
round-headed tree becomes a sheet of white blossom during May and June.
The reddish-brown fruits are small for a Medlar, and ripen in October.

P. TORMINALIS.--Wild Service Tree. A native species of small growth,
with ovate-cordate leaves, and small white flowers. P. torminalis
pinnatifida, with acutely-lobed leaves, and oval-oblong fruit may just
be mentioned.

P. VESTITA.--Nepaul White Beam. Nepaul, 1820. In this species the leaves
are very large, ovate-acute or elliptic, and when young thickly coated
with a white woolly-like substance, but which with warm weather
