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.
