Pterostyrax corymbosa is a deciduous small- tree with
gray-brown barks, many inhabiting somewhat damp locations in
deciduous forests in mountainous regions and growing to 6-10m in
height. Leaves with 1.5-2.5cm-long petioles are alternate,
broad-oblong, or obovate, with tips shortly pointed, bases somewhat
circular, margins with shallow serrations bending inward, and the
ends having glandular protrusions. Flowers, white, set themselves
many in compound racemes of 8-12cm in length; corollas, about 1cm
long, deeply cut in 5, with fine stellate hairs on the surfaces.
Stamens are 10 in number, longer than the corollas, and filaments
are inches on the inside of the lower half. Stigmas are longer than
the stamens, with many long hairs on styles. Bloom time: May-June. |
