Sycopsis

This is a genus of two or three species of evergreen shrubs and trees from woodland in China, the Himalayas and SE Asia. The word Sycopsis comes from the Greek word "appearance".

Leaves are simple, alternate, ovate to oblong, entire or finely toothed.

The flowers, which appear in spring, have racemes of small clusters of stamens and no petals.

The only species in general cultivation is Sycopsis sinensis.  A bi-generic hybrid between Sycopsis sinensis and Parrotia persica called x Sycoparrotia semidecidua is also in cultivation.

Sycopsis sinensis

Sinensis means Chinese and this species was introduced from Central China in 1901 by Ernest Wilson.

It is a conical shrub with dark green, oblong, leathery leaves, which are pale green beneath and up to 10cm (4in) long.

Sycopsis sinensis flowers

In spring, dense clusters of flowers, up to 2.5cm (1in) across, develop from chocolate-brown, woolly buds. The flowers have no petals and consist of yellow stamens and red anthers.

It is cultivated for its flowers and leaves and can be used in a shrub or woodland garden.
