Glabrous unarmed shrubs, often unbranched (sympodial). Leaves with a petiole having a dilated sheath encircling the stem and (in dried material) a constriction at the apex, and with a leaf-blade either unifoliolate or digitately compound, the central leaflet, or the three central leaflets, sometimes digitately lobed or compound. Inflorescence terminal (but sympodium often continued by axillary branching), the peduncle bearing umbellately arranged branches which terminate either in umbellules or in cymes. Flowers male or hermaphrodite, the male flowers either in distinct inflorescences or towards the periphery of mixed inflorescences. Petals 5-6, narrowed below into a distinct claw, and above into a long incurved process. Stamens 5-6; Ovary inferior, with two uni-ovulate cells. Fruit strongly compressed, 2-seeded (or one aborted), with a longitudinal furrow between the seeds;


Asia-Tropical: New Guinea present; Philippines (Philippines present); Sulawesi (Sulawesi present), Australasia: Queensland (Queensland present), Solomon Is present
5 spp., Solomon Is., Queensland, and in Malesia (3 spp.): Philippines, Celebes and throughout New Guinea.


The leaves are palmately divided or they may be reduced to a single leaflet, especially on the upper branches of M. schlechteri. The central leaflet, or the three central leaflets, are either lobed or compound, a character rarely found in other genera of this family. Another foliar character rare in the family is the insertion of the leaf-sheath round the whole circumference of the stem. This character occurs also in a section of Polyscias, but is more typical of Umbelliferae. The narrow base of the petal is also very rare in the family, but is characteristic of Umbelliferae. The constantly 2-celled ovary is also typical of Umbelliferae, but other characters of the fruit appear to justify the retention of these plants in the Araliaceae. Reasons for regarding Anomopanax as congeneric with Mackinlaya are given by Philipson (l.c.).
