FRAXINUS ORNUS (_syn F. argentea, F. rotundifolia_, and _Ornus
europea_).--Manna Ash. South Europe, 1730. This is a handsome tree,
especially when young and vigorous, and by far the most ornamental
species in cultivation. For planting in situations where large-growing
subjects would be out of place this is a valuable tree, while the
wealth of flowers renders it particularly interesting and effective. It
0 feet in height, with leaves not unlike those of the
common Ash, and conspicuous panicles of light, feathery, white
petaliferous flowers, produced usually in great abundance all over the
tree. Perfectly hardy.
F. Ornus serotina alba and F. Ornus serotina violacea are beautiful
seedling forms that were raised in France, and on account of their
dwarf habit and profusion of flowers are well worthy of attention. The
flowers of the first-named variety are pure white, the stamens having
at first yellow anthers, which speedily turn to a rich blackish-brown.
The other differs but little, only in the flowers, which are of a
distinct greyish-violet hue, while the leaves are of a darker shade of
green, and the leaflets longer and narrower.
F. MARIESII.--Northern China, 1880. This is hardy in most parts of the
country. The whole tree is quite glabrous except the petioles, which
are clothed with a dense pubescence. Flowers pure white, and arranged
in large dense panicles.
