::summary Genus of flowering plants ::

|image = M thunbergii.JPG |image_caption = Machilus thunbergii leaves, also known as Persea thunbergii |taxon = Machilus |authority = Nees |subdivision_ranks = Species |subdivision = See text Machilus is a genus of flowering plants in the family Lauraceae. It is found in temperate, subtropical, and tropical forest, occurring in China, Korea, Japan, Taiwan, Indochina, the Indian subcontinent, Malaysia, Indonesia, and the Philippines.

Its delimitation versus the closely related avocados (genus Persea) has been disputed, with some Persea species such as coyo (P.schiedeana) sometimes placed in Machilus, or all of Machilus being included in Persea. As circumscribed here – distinct from Persea but excluding American species – Machilus currently includes about 100 species.

Description

Machilus are evergreen trees or shrubs, some species growing as much as 30 m tall. Their entire, pinnately veined leaves are alternately borne along the stems. Their bisexual flowers are borne in inflorescences that are usually paniculate, terminal, subterminal, or arising from near base of branchlets, with long peduncles or rarely without peduncles. Perianth tubes are short; perianth lobes 6 in 2 series, equal, subequal, or occasionally outer ones conspicuously smaller than inner ones, usually persistent, rarely deciduous. Fertile stamens 9 in 3 series, anthers 4-celled, 1st and 2nd series of stamens eglandular, anthers introrse, 3rd series of stamens glandular, anthers extrorse or lateral, glands stipitate to sessile. Staminodes in 4th series, sagittate. Ovary sessile; stigmas small, dish-shaped or capitate. Fruits are fleshy, globose, rarely ellipsoid or oblong, subtended at base by persistent and reflexed perianth lobes; the fruiting pedicel does not become enlarged.
