thickened. {Tor. and Gray). Decaying leaves of a fine reddish yellow.
Naked young wood reddish brown.
Branches slender, pendulous, and crooked ;
often taking root, in the manner o f those of
many species of Dicus. Bark smooth ; green
when young, white when fully grown. Leaf
the length o f the finger, upon rather a short
footstalk, membranaceous, heart-shaped, with
7— 9 lobes, and 7—9 nerves ; smooth above,
except hairs in the axils o f the nerves ; downy
beneath, and in the axils of the nerves woolly :
lobes ovate, acute, and acutely serrated ; the
sinuses acute : the nerves radiate from the tip
of the petiole, and one extends to the tip o f
each lobe. Flowers o f a middling size, in
nodding corymbs, that are on long peduncles.
{Hook. Fl. Bor. Amer.) This is a very marked
136. ri'cer circinàtum.
and beautiful species; distinguishable, at sight, by the regular form o f its
leaves, and their pale reddish green colour. Though this fine tree has been
in the country since 1826, it seems to have been comparatively neglected, for
there is no good specimen that we know of in the neighbourhood o f London.
At High Clere, a thriving tree has ripened seeds for some years p a s t; so th a t
there can be no doubt o f its hardiness.

Ovaries downy. (Don’s MiU.) A middle-sized tree. North America, from
lat. 43° to Georgia. Height in America 10 ft. to 40 ft. ; in England 30 ft.
to 50 ft. Introduced in 1725. Flowers small, pale yellowish p u rp le ;
March and April. Keys brown ; ripe in July.
Varieties. There are several names in nurserymen’s catalogues, such as A.
coccineum, A. macrocarpum, A. flóridnm, A. Pàvia which are only very
slight varieties of A. eriocarpum. The last-named variety, introduced by
Messrs. Booth, has received the absurd name o f Pàvia, from the upper
surface of the leaves being slightly wrinkled, somewhat in the manner o f
those of the horsechestnut. As the species seeds freely, endless varieties
may be obtained from seed beds.

Distinguished from A.
rùbrum by the leaves
being more decidedly 5-
lobed, the lobes deeply cut,
and the whole leaf more
tomentose. A very desirable
species, from the rapidity
o f it.s growth, the
graceful divergent direction
of its branches, the beauty
o f its leaves, and the profusion
o f its early flowers.
In mild seasons, these flowers
begin to burst from
their buds in the first week
137. jl'cer erir)cárpunr
in January ; and they are
often fully expanded by the end of February or beginning of March. It
requires a deep free soil, and more moisture than most of the other species.
I t ripens its seeds, both in America and Britain, by midsummer, or earlier j
and, if these are immediately sown, they come up, and produce plants which
are 8 or 10 inches high by the succeeding autumn.
