BOTANIC DESCRIPTION<br />

<strong>Harungana</strong> <strong>madagascariensis</strong> is a small to medium sized bushy tree 4-7<br />

m in height, sometimes reaching 10-25 m; it is much branched with a<br />

cylindrical trunk. Crown is golden-green, deep and spreading with fine<br />

almost whorled branches. Bole is often rather angular and forked. Bark<br />

greyish or red-brown rather rough and scaly, frequently vertically fissured,<br />

with very small vertically arranged scales which flake off easily; slash<br />

bright orange, thin, rather wet and turgid, but will peel off in long strips,<br />

and when cut, brilliant, almost florescent orange lat<strong>ex</strong> flows abundantly<br />

and by it, the tree can be recognized immediately. This orange paint-like<br />

sap <strong>ex</strong>udes if leaves are snapped off or if branches are broken. Most parts<br />

of the tree are covered with fine stellate hairs.<br />

Leaves opposite, simple, ovate or ovate elliptic, 6-20 x 3-10 cm, glossy,<br />

dark green above with prominent veining, the under surface with dense<br />

rusty hairs which may be partially lost by maturity but usually persist, and<br />

rather numerous lateral nerves, which are prominent beneath; young<br />

leaves at the ends of branches are distinctive and remain tightly pressed<br />

together until quite large, the brown lower surfaces quite characteristic;<br />

ap<strong>ex</strong> tapering; base broadly tapering to rounded; margin entire; petiole 1.5-<br />

3 cm long.<br />

Flowers whitish or cream, about 5 mm in diameter, sweetly almond<br />

scented, in dense many-flowered flat terminal heads (corymbose<br />

panicles), 8-20 cm in diameter, the stalks and calyx covered with short<br />

rusty hairs, bis<strong>ex</strong>ual; 5-merous; sepals glandular; petals with hairs on the<br />

inside and black gland dots; stamens in 5 clusters, each cluster made up<br />

of a few stamens joined for most of their length, with a sterile cluster, or a<br />

facsiclode between each fertile cluster; ovary 5-chambered.<br />

Fruits berry-like (drupe), 2-4 mm in diameter, greenish-orange becoming<br />

red when mature, in heavy, massed, terminal heads up to 25-30 cm in<br />

diameter, rather dry, with a crustaceous pericarp enclosing the 5 pyrenes,<br />

2-4 seeded.<br />

BIOLOGY<br />

In southern Africa, flowering can be observed from January to April<br />

followed by fruiting until October. In Sierra Leone, flowering begins<br />

sparingly in May, reaches its height in August and September and then<br />

tapers off up to about December; flowering is always very profuse. Fruits<br />

of the usually evergreen tree ripen from September up to January.<br />

ECOLOGY<br />

H. <strong>madagascariensis</strong> occurs at medium to low altitudes in evergreen forest, at forest margins and along river and stream<br />

banks. It is a common and widely distributed tree from the Sudan to South Africa, often a pioneer when a forest has been<br />

cleared. The species is widespread in tropical Africa, and is found in clearings in forest regions and fringing forest in<br />

savanna regions. It is found all over Sierra Leone in young farm bush, usually associated with Trema musanga and<br />

Nauclea latifolia. In Uganda, it is found in forest edges and in secondary scrub, and is usually associated with Maesopsis<br />

eminii and Trema orientalis. The trees have a general brownish-yellow appearance in the field<br />

It form dense thickets which <strong>ex</strong>cludes, other species and can possibly become a permanent component of tropical<br />

rainforests, potentially making it weedy.<br />

BIOPHYSICAL LIMITS<br />

Altitude: 0-1 800 m, Mean annual rainfall: 1100-1800 mm, Mean annual temperature: 20-32 deg.C<br />

The map above shows countries where the species has been planted. It does neither<br />

suggest that the species can be planted in every ecological zone within that country,<br />

nor that the species can not be planted in other countries than those depicted. Since<br />

some tree species are invasive, you need to follow biosafety procedures that apply to<br />

your planting site.<br />

PRODUCTS<br />

Fuel: H. <strong>madagascariensis</strong> is a source of firewood and is used in the production of charcoal.<br />

Timber: The wood is pink, orange-red to yellow and can have most attractive colouring in larger specimens. The tree is<br />

not used commercially because it seldom grows to a merchantable size, though the rather light wood is used to make<br />

poles for building houses.<br />

Tannin or dyestuff: Sap <strong>ex</strong>tracted from the bark of orange-milk tree is used to dye palm leaves for making mats and<br />

other craft items.<br />

Medicine: Sap is used in the treatment of scabies and as an anthelmintic (tapeworms), while leaves are used as a<br />

remedy for hemorrhages, diarrhoea, gonorrhoea, sore throats, headaches and fevers. Resin from the flower stalks is<br />

believed to ease colic and to check infection after childbirth, while a decoction of the bark is drunk as a remedy for<br />

malaria or jaundice. Roots are used to hasten breast development in young women while roots and bark are boiled in<br />

water, and the infusion drunk twice a day, to interrupt the menses. Young leaves are sometimes used a medicine for<br />

asthma and fruits are occasionally used in cases of abortion in the belief that the red juice averts bleeding.<br />

TREE MANAGEMENT<br />

H. <strong>madagascariensis</strong> coppices easily and is a fast growing species which requires thinning after planting, for adequate<br />

growth.<br />

GERMPLASM MANAGEMENT<br />

Seeds should be kept in sealed containers and sown within 2 months. To prevent insect attack on seeds, ashes need<br />

to be added.<br />

PESTS AND DISEASES<br />

Seeds are susceptible to insect attack.<br />
