Anecdotes on plants

Origin	Zhejiang, Fujian.
Ecology	Chekiang Machilus is known as an early successional tree which is fast growing and light demanding. Including Chekiang Machilus, Machilus ssp. such as Machilus breviflora (Short-flowered Machilus) and Machilus pauhoi (Many-nerved Machilus) have occupied a discernible proportion of tree canopy of the forests and ruled out the species which grow rampantly in grasslands and are less acclimatised to shady environments.
Vitality	Chekiang Machilus shows excellent tolerance to shade and barren soils.
Application	Its branches and leaves are valued for versatile medicinal functions; they are usually used for dispersing swelling, relieving phlegm, blood and pain, and curing bronchitis and scalds.

Traits for identification

Growing habit	Evergreen tree.
Height	To 10 m.
Stem	Bark brown, with scattered labiate lenticels. Young branches with notable bud scale scars at the base.
Leaves	Simple leaves alternate, commonly aggregated at the apex of branchlets. Leaf blade oblanceolate, base tapering, apex often cuspidate, puberulent when young, becoming glabrous later, leathery or thinly leathery when mature, midrib of abaxial leaf apparently raised. Large bud scale is a characteristic of Chekiang Machilus.
Flower	Panicles at the base of current year's branchlets. Tepals 6, yellow green, puberulent.
Fruit	Drupes globose, fleshy, black at maturity.
Flowering period	February in Hong Kong.
Fruiting period	April to May in Hong Kong.
