raptera, though in southern parts
of the country it forms a neat, healthy bush, and flowers freely. It is
distinguished, as the name indicates, by having two wings to the seed
vessel, H. tetraptera having four.

H. HISPIDA (_syn Pterostyrax hispidum_).--Japan, 1875. This is a shrub
of perfect hardihood, free growth, and very floriferous. The flowers,
which are pure white, and in long racemes, resemble much those of the
Snowdrop Tree. Leaves broad and slightly dentated. It is a handsome
shrub, of free growth, in light, sandy loam, and quite hardy even when
fully exposed.

H. PARVIFLORA has smaller flowers than those of our commonly-cultivated
plant.

H. TETRAPTERA.--Snowdrop Tree. North America, 1756. This is a very
ornamental tall-growing shrub, of somewhat loose growth, and bearing
flowers which resemble, both in size and appearance, those of our common
Snowdrop. It is one of the most ornamental of all the small-growing
American trees, and richly deserves a place in every collection, on
account of the profusion with which the flowers are produced in April
and May. They are snow-white, drooping, and produced in lateral
fascicles of eight or ten together. It is a native of river banks in
North Carolina, and is well suited for cultivation in this country.
Light, peaty soil will grow it to perfection.

HALIMODENDRON.

HALIMODENDRON ARGENTEUM (_syn Robinia Halimodendron_).--Salt tree. A
native of Asiatic Russia (1779), having silvery foliage, and pink or
purplish-pink flowers, axillary or fascicled. It is a neat and pretty
shrub, that is rendered valuable as succeeding well in maritime
districts. Quite hardy and of free growth in sandy soil.

HAMAMELIS.

HAMAMELIS JAPONICA.--The Japanese Witch Hazel. Japan, 1862. This is a
small species with lemon-yellow flowers. H. japonica arborea is a taller
growing variety, with primrose-yellow petals, and a deep claret calyx.
The flowers are borne in clusters in early spring. Rarely in this
country do we find this species of greater height than about 8 feet, but
it is of bushy growth, though somewhat straggling in appearance. As
early as the beginning of January this Witch Hazel may be found in
bloom, the bare branches being studded here and there with the
curious-shaped flowers, these having bright yellow, twisted petals and
reddish calyces. H.j. Zuccarinianais a very desirable free-flowering
variety, with pale yellow petals and a greenish-brown calyx.

H. VIRGINICA.--V
