Baccaurea bracteata, called Rambai Tikus and sometimes golden tampoi, is a humid-tropical tree of the Phyllanthaceae. It is grown primarily as a botanical and rare-fruit subject: the ripe fruit has edible yellow pulp, but its flavour is sour.[1] The species is dioecious, so a fruiting planting needs both male and female trees.[2]
Description[edit | edit source]
The plant ranges from a shrub-sized tree to about 25 m tall, with a dense crown and a bole reported at roughly 4–40 cm in diameter. Leaves are alternate, simple, and ovate to elliptic; the blades are papery to somewhat leathery and may reach about 21 cm in length.[3] Male flower clusters can be long and branched, with conspicuous leaf-like bracts; female clusters carry fewer, larger flowers.[4]
The fruit is a fleshy capsule, usually globose to three-shouldered and about 19–25 mm across. It changes to reddish brown or related orange-brown tones and opens partly into three sections, exposing three to six seeds in yellow pulp.[1]
Cultivation[edit | edit source]
Soil and water[edit | edit source]
In nature, Baccaurea bracteata occurs in freshwater, peat, and heath swamps as well as rainforest, often on white sand. These settings point to a warm, organic, moisture-retentive site, while the species' occurrence in sandy kerangas forest also indicates that good drainage and steady aeration around the roots matter even where rainfall is high.[5] Keep a cultivated tree evenly watered during active growth; avoid allowing a container or planting hole to remain stagnant unless the root zone is designed for wet conditions.
Sun and humidity[edit | edit source]
The species is native to humid tropical forest and is listed for full sun in Singapore horticultural guidance.[1] Provide high atmospheric humidity and protection from drying winds while a young tree establishes. Gradually increasing light is a practical approach for nursery plants; an established specimen can use open sun where water supply and leaf temperature are manageable.
Seasonal changes[edit | edit source]
Flowering and fruiting are recorded through much of the year for the species and its genus, although an individual tree may respond to local rainfall and temperature.[6] Maintain moisture through dry spells rather than relying on a sharp dry-season stress. There is no well-established species-specific schedule for years to first fruit, so that value is left unreported here.
Propagation[edit | edit source]
Fresh seed is the most directly documented method. Seed sown fresh usually germinates within a few days, so sow it promptly after removing it from ripe pulp in a clean, free-draining medium and keep the medium evenly moist.[5] Because the species is dioecious, seedling sex cannot be assumed; several seedlings or a known female combined with a compatible male are needed when fruit production is the goal.[2]
Flowering, fruiting, and harvest[edit | edit source]
Flowers are borne in clusters on the branches. Male clusters may reach about 16 cm and contain many small red flowers, while female clusters are shorter or occasionally longer and carry yellowish, greenish, or red-brown flowers. Insect pollination is recorded.[1] Fruit develops on short shoots along twigs and branches. Harvest when the rind has reached its mature reddish-brown colour and begins to split; handle the soft capsules carefully because opening exposes the pulp and seeds.[1]
Fruit and uses[edit | edit source]
The yellow pulp around the seeds is edible raw but sour. It is best treated as a fresh tasting fruit or an ingredient for preparations where acidity is useful; species-specific processing methods are not well documented.[3] The wood is reported as useful, and shoots have been used locally in construction, but those uses are not reasons to harvest a rare cultivated tree unnecessarily.[1]
