HALESIA DIPTERA (_syn H. reticulata_).--North America, 1758. This is not

so suitable for our climate as H. tetraptera, 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 hardi
ood, 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


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.
