May Appeal 2026

Please help keep TSO growing!

IDS Trees and Shrubs Online has become a fundamental source of reliable information about cultivated woody plants, freely available to everyone, everywhere. We hope you find it useful.

For the first time we are asking our users if you could support us.

If everyone who uses TSO during May 2026 gives just £10, we would cover our costs for a whole year, enabling us to accelerate our work.

Glossary

acuminate
Narrowing gradually to a point.
carpel

glabrous
Lacking hairs smooth. glabrescent Becoming hairless.
ovate
Egg-shaped; broadest towards the stem.
perfect
(botanical) All parts present and functional. Usually referring to both androecium and gynoecium of a flower.

A large shrub or small tree in the wild. Leaves finely double-serrate, oblong or oblong-ovate, acuminate, up to 212 in. long and 58 in. wide on fertile branchlets, much longer on extension growths, almost sessile, glabrous, very white beneath. Flowers greenish, borne with the unfolding leaves, in short downy racemes on leafy peduncles. According to the original description, they are perfect, with only a single carpel, but there is considerable disagreement concerning the distribution of the sexes in this genus (and on whether or not flowers with two carpels produce fertile twin-fruits).

This species was discovered by Wilson in western Hupeh in 1907–8 during his first expedition for the Arnold Arboretum. It is rare in British gardens and would probably not have survived but for its being preserved and propagated by Messrs Hillier. It is in truth of little garden value, the most interesting feature being the white undersurface of the leaves.
