Among the woody plants which are hardy in the latitude of 
New York this must be considered one of the most attractive, when 
in full bloom, on account of its profusion of fragrant cream-colored 
flowers in long pendulous clusters. In this latitude it is usually a 
large shrub, but in a situation which is congenial it will develop into 
a small tree, and he who possesses a healthy vigorous tree of this 
species may consider himself fortunate. It flowers in June, and is 
hardy as far north as Massachusetts in sheltered situations. There 
are several specimens of it in the New York Botanical Garden: in 
the form of a shrub at the fruticetum; but the best specimen is a 
small tree, about twenty feet tall, along a walk not far from the 
entrance to the elevated railway. Specimens of this were secured 
by exchange with the Royal Gardens, Kew, England, in 1897, and 
it is from one of these that the illustration was prepared. It is 
sometimes sold under the name oe corymbosa, a species 
quite different and rarely seen in cultiv: 
It will grow in any soil of cated ae but it does best 
in a moderately sandy loam. Propagation may be readily effected 
by seeds or by layering; also by greenwood cuttings under glass. 
The genus Pterostyrax, native of China and Japan, has four 
known species, three found in both China and Japan, the fourth 
being confined to China. The genus was, and is sometimes now, 
united with Halesia, a group of plants peculiar to the southeastern 
United States. It differs in several essential characters, and is now 
considered distinct. 
The hispid winged storax sometimes attains a height of fifty feet, 
“ad commonly much less than this in cultivation, often only a 
alternate leaves are on petioles up to an inc

acute or shortly acuminate apex and a wedge-shaped base; the 
upper surface is glabrous, t the lower paler and glabrous or finely 
white tomentose, the veins pubescent. xillary panicles, with 
two or three leaves at the base, are pendulous, up to six saihee long,
