Native to tropical Africa i. This species was probably madagascsriensis as an ornamental tree in gardens the wetter parts of northern Australia. Not yet widely naturalised in Australia, and currently only found in the wetter tropical areas of far northern Queensland particularly near Babinda.
A potential weed of disturbed rainforests, forest gaps and margins, roadsides and drainage areas in tropical and sub-tropical regions. A small to relatively large tree usually growing m tall, but occasionally reaching up to 20 m in height. It can sometimes also grow as a large multi-stemmed shrub.
Antibacterial activity of Harungana madagascariensis leaf extracts.
The stems are covered with fine star-shaped i. Branches and young madagaxcariensis exude a bright orange coloured sap when damaged. The leaves are oppositely arranged, and the young leaves at the tips of the branches are tightly pressed together i.
Mature leaves are relatively large haruhgana long and cm wide and egg-shaped in outline i. They have rounded i. These leaves are borne on stalks i. The upper leaf surface is dark green and hairless i. The small whitish coloured flowers are very numerous and arranged in dense clusters at the tips of the branches i. The branches of these flower clusters are covered with coarse rusty-coloured hairs and the fragrant flowers are dotted with black glands i. Each flower has five tiny sepals, five small whitish petals that are somewhat hairy, and numerous small stamens that are arranged into five clusters i.
Flowering occurs throughout the year, but mostly during late spring and early madagascariwnsis.
The small rounded fruit 2. These fruit turn brown as they ripen and are borne in large clusters at the tips of the branches.
This species reproduces mainly by seed, but it also spreads laterally via the development of suckers from its roots. The seeds are mostly dispersed by fruit-eating i. Its spreading roots produce suckers, and so do damaged plants, enabling it to out-compete other species. Although harungana Harungana madagascariensis is currently restricted to relatively disturbed areas, there is concern that this plant may become a permanent component of tropical rainforest communities.
Harungana Harungana madagascariensis is quite distinctive, and can be readily distinguished by its orange sap and yellowish-brown to orange coloured growing tips.
