''Baccaurea polyneura'', known as Pupuan or Jentik-jentik, is a humid-forest fruit tree native to Peninsular Thailand and western Malesia. Its small fruits grow in clusters on long stems and split open to reveal reddish pulpy segments. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

== Description ==

The tree forms a dense crown and grows about 5–30 m tall, with a bole about 10–90 cm in diameter and small buttresses. It occurs as a mid-canopy tree in primary, secondary, and swamp rain forest. The globose fruits can reach about 26 mm in diameter and are borne in clusters on stems up to about 24 cm long. <sup>[[#cite_note-3|[3]]]</sup>

== Cultivation ==

=== Soil and water ===

Wild plants are recorded from sand, clay, loam, and granite soils, and from hillsides, ridges, alluvial sites, and swamp forest. These records indicate tolerance of varied native substrates, but they do not define a universal drainage or irrigation prescription for cultivation. A free-draining medium that remains evenly moist is a reasonable habitat-based starting point, especially where heavy rain or swampy conditions can be separated from stagnant container water. <sup>[[#cite_note-3|[3]]]</sup>

=== Sun and humidity ===

The species is associated with humid tropical forest, including mid-canopy positions. As a habitat-based cultivation inference, warm, humid conditions, protection from drying wind, and filtered light or gradual acclimation to stronger sun are prudent starting points for a forest-associated tree. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

=== Seasonal changes ===

Rainforest and swamp-forest habitat indicate a warm, humid growing regime rather than a pronounced cool-season dormancy. Flowering and fruiting may occur throughout the year, but local crop timing can vary. Keeping the root zone from drying sharply during a dry season while avoiding stagnant wetness during prolonged rains is a habitat-based precaution; the account does not define a species-specific irrigation threshold. <sup>[[#cite_note-3|[3]]]</sup>

== Propagation ==

''Baccaurea polyneura'' is dioecious, so male and female plants are needed when fruit and seed are both desired. Fresh seed is the documented propagation route, and germination is described as usually occurring within a few days. Sowing promptly after extraction is a practical freshness-based inference rather than a measured storage protocol. <sup>[[#cite_note-3|[3]]]</sup>

== Flowering, fruiting, and harvest ==

Flowering and fruiting may occur throughout the year. The fruit is gathered from wild trees and is sometimes sold in local markets; harvest timing varies by site. <sup>[[#cite_note-3|[3]]]</sup>

== Fruit and uses ==

The ripe fruit is eaten raw. When pressed or pinched, the globose fruit splits to expose one to three reddish pulpy segments, each containing a seed. The recorded flavor is sour with some sweetness. <sup>[[#cite_note-3|[3]]]</sup>
