Properties
Botanic
An evergreen, medium-sized to large tree up to 40(-60) m tall, all parts smelling of garlic; bole columnar, branchless for up to 25 m, up to 80(-150) cm in diameter, often piped, occasionally with small buttresses; bark surface shallowly fissured and flaking into thin rectangles, grey-brown to dark red-brown, inner bark fibrous, purplish-red, inwards with orange flecks.
Leaves arranged spirally, simple, entire, exstipulate; petiole swollen distally.
Flowers in an axillary, short raceme, 4-5-merous; calyx cup-shaped, margin wavy to toothed; petals reflexed, white, hairy inside; stamens 8 or 10, inserted in pairs about halfway on the petal; ovary superior, imperfectly 3-4-locular with a single ovule in each cell, stigma minutely lobed.
Fruit a thinly fleshy, subglobular, 1-seeded, green drupe; endocarp woody with vertical strands.
Seedling with hypogeal germination; cotyledons not emergent; hypocotyl not developed; epicotyl with a few scale leaves followed by normal, spirally arranged leaves.
Sapling leaves are alternate-distichous on the branches but arranged spirally on the orthotropic leader.
Biology
In Peninsular Malaysia flowering is in January-July and fruiting more or less throughout the year; in Borneo fruiting is usually in June-September.
Habitat
S. borneensis occurs scattered but may be locally common or even gregarious in primary rain forest,
Cultivation and Marketing
Propagation
S. borneensis can be propagated by seed or by wildlings. The seeds show about 70% germination in 11-32 months, fruits have about 40% germination in 9-16 months. Stumps may coppice easily.
Management
For optimal growth it requires well-drained soils.
Germplasm
Before storage seeds should be sun-dried for about 10 days. There are about 27 000 dry pyrenes/kg.
Uses and Function
Food: In Sarawak the young leaves are eaten as a vegetable. The fruit is edible and is sometimes used as a substitute for garlic.
"Medicine: The fruits and also an infusion of the bark are sometimes used as an antidote for ""antiaris"" (Antiaris toxicaria Lesch.) poisoning. An extract from the fruits shows antimicrobial activity."
Timber: The wood of Scorodocarpus is used for medium to heavy construction under cover (beams, joists, posts, door and window frames, flooring, rafters), bridge building, salt-water piling (with bark on), boat keels, mine props, transmission posts, agricultural implements and sleepers in temporary railway lines.
