Trachycarpus fortunei, the Chinese windmill palm,windmill palm or Chusan palm, is a palm native to central China (Hubei southwards), southern Japan (Kyushu), south to northern Burma and northern India, growing at altitudes of 100–2,400 m (328–7,874 ft). It is a fan palm, placed in the family Arecaceae, subfamily Coryphoideae, tribe Trachycarpeae.
Trachycarpus fortunei grows to 12–20 m (40–70 ft) tall on a single stem the diameter of which is up to 15–30 centimetres (6–12 in). The trunk is very rough with the persistent leaf bases clasping the stem as layers of coarse fibrous material. It is a fan palm with the leaves with the long petiole bare except for two rows of small spines, terminating in a rounded fan of numerous leaflets; each leaf is 140–190 centimetres (55–75 in) long, with the petiole 60–100 centimetres (24–39 in) long, and the leaflets up to 90 centimetres (35 in) long. It is a somewhat variable plant, especially as regards its general appearance and some specimens are to be seen with leaf segments having straight and others having drooping tips.
The flowers are yellow (male) and greenish (female), about 2–4 millimetres (79⁄1000–157⁄1000 in) across, borne in large branched panicles up to 1 metre (3 ft 3 in) long in spring; it is dioecious, with male and female flowers produced on separate trees. The fruit is a yellow to blue-black, reniform (kidney-shaped) drupe 10–12 millimetres (39⁄100–47⁄100 in) long, ripening in mid autumn.
Occasionally a male plant of T. fortunei, besides the usual spadices, produces a few other spadices carrying really hermaphroditic flowers. Completely fertile, these are almost exactly like the male flowers, but are a little larger and with the carpels well evolute, the latter about as long as the filaments, furnished with a ring of silvery hairs all round.
