Mallotus philippensis Seeds | Kamala Tree

Kamala Tree (Mallotus philippensis) with clusters of red-glanded fruit capsules and glossy leaves — Kamala Tree (*Mallotus philippensis*): Euphorbiaceae, the dye tree of the Asian lowland forests.

LATIN NAME: Mallotus philippensis

COMMON NAME: Kamala Tree

Plant Profile

The Kamala Tree is a small to medium evergreen tree of the spurge family, spread across the lowland forests from India through Southeast Asia to northern Australia. Its leaves are glossy, heart-shaped at the base and often three-lobed, carried on reddish stalks, and the young growth is attractively silky. The flowers are small and unremarkable, but the fruit is not: the capsules are densely covered in a fine, brilliant orange-red powder of glandular hairs, and a fruiting tree looks dusted with paprika.

That powder is the plant’s fortune. It has been harvested for centuries as the dye and drug kamala, brushed off the ripe capsules and traded across Asia, and the tree grows readily in the open, disturbed country its spread implies.

Science & Biotechnology

The orange-red powder is the source of rottlerin, a compound whose research history is a cautionary tale: it was long sold as a selective inhibitor of a specific signalling enzyme and used in hundreds of published studies on that basis, until careful work showed its apparent effects came substantially from other actions, including disruption of mitochondrial function. The episode is now a standard citation in discussions of chemical-reagent validation. The dye itself has a long commercial record, used on silk and wool and as a traditional anthelmintic in veterinary practice across South Asia, and the chemistry of the gland hairs has been thoroughly worked out.

Ecologically the fruit’s colour advertises to birds, which disperse the seed, and the tree is a fast colonist of forest gaps and roadsides across its enormous range.

Uses & Benefits

In a warm, frost-free garden it is a fast, glossy, small shade tree with the paprika-dusted fruit as a conversation piece in autumn, and it tolerates the poor, open ground and dry spells that limit fussier trees. Its silver-silked young growth is ornamental in its own right.

The dye is a legitimate home use: the powder from ripe capsules colours wool and silk in warm yellows to deep orange with an alum mordant, a craft tradition still alive among natural dyers. Its drug history, like the rottlerin story, belongs in the literature rather than the medicine cabinet.

Growing from Seed

Clean the pulp from the ripe fruit and sow fresh into a free-draining compost, covering to the seed’s own depth and holding at 22 to 27 °C with even moisture; germination follows within three to five weeks. Pot the seedlings on early, as the root run deepens quickly, and grow them in full light.

Plant out into any reasonably deep soil in full sun where winters are frost-free, spacing for a ten-metre crown, and water through the first two summers. The tree grows fast, fruits young, and once established needs nothing beyond occasional shaping. In cooler climates it makes a fine, fruiting pot subject for a warm conservatory.

Our Take

The tree dusted with paprika: a fast, glossy small tree whose orange-red fruit powder dyed silk across Asia and unsettled a corner of pharmacology. Easy in warm gardens.
