Halesia tetraptera. - Four-winged Halesia. - A native of Carolina, where it is found growing on the banks of rivers. It is an ornamental shrub, five or six feet high, valuable for its early flowering in May. The flower hangs in small bunches all along the branches, each bud producing from four to eight or nine; they appear before the leaves, and are of a snowy whiteness, and last for two or three weeks.
Halesia diptera. - Two-winged Silver Bell Tree. - This species is described in Downing's first volume of the Horticulturist as follows :- "The present species is a much rarer one than the last. Its native country is Georgia and Carolina, but it is hardy here, and is well entitled to a prominent place in the pleasure-grounds. It differs very strongly from the common species, in both the larger size and the purer white of the flowers, and also in foliage, which is twice as broad as that of the four-winged sorts. The seeds have, as the name indicates, only two-winged appendages. Though this species is fre quently advertised for sale, yet it is rarely found true to name. There are two or three fine specimens of the true Halesia diptera in the excellent nursery-grounds of Mr. William Reid, at Murray Hill, New York city, which have strongly excited our admiration whenever we have seen them in bloom. They blossom in June, three or four weeks later than H. tetraptrra; the blossoms are large and numerous, and of a pure and snowy whiteness, and remain a good while in flower. Altogether, we consider the Two-winged Silver Bell as a hardy shrub of great beauty, and one that should be largely propagated, and introduced into every collection. It cannot be very difficult to obtain seeds from the South, and Mr. Reid informs us that this species ripens seeds in the open borders of his grounds."
