Natural populations

Mallotus philippensis grows north of theHunter River in New South Wales, along the coast of Queensland, the Darwin coast and is also through the warmer regions of Asia including India. Plants grow mainly in microphyll to notophyll rainforests and vine thickets, but are frequently found in gullies or on ridges in open forest especially at rocky sites with some fire protection [31]. No variation is recorded for this species.

Flowering and seeds

Mallotus flowers and fruits throughout the year [31], although the main season for producing fruits is in summer. Germination is only successful if sown from very fresh seed, although it is reported to be often poor due to factors such as drought and insect attack affecting seed quality [109, 111]. Seed is remarkably short lived for a pioneer species [109].

Cultivation and uses

The wood is suitable for tool handles and building [31]. The granules which cover the ripe fruit are used in India as a dye ('kamala') for dyeing silk and wool bright orange, although is now rarely used as a dye as it is much too expensive to compete with synthetic dyes [111]. It has medicinal uses in India [111].
