:Protologue: Malesia 3: 251, t. 21 (1889).

:Family: Bombacaceae

== Synonyms ==

*''Lahia kutejensis'' Hassk. (1858).

== Vernacular names ==

*Brunei: durian kuning
*Indonesia: lai, ruas, sekawi (Dayak, Kalimantan), durian tinggang (Malay, Kalimantan)
*Malaysia: durian merah (Sabah), rian isu (Iban, Sarawak).

== Distribution ==

Borneo (Kalimantan, Sarawak, Brunei, Sabah); often cultivated elsewhere in Malesia (e.g. Java) for the fruits or as an ornamental tree.

== Uses ==

The wood is reputed to be used as durian. The aril around the seed is edible and the fruit is popular.

== Observations ==

*A small to medium-sized tree up to 30 m tall, with bole branchless up to 12 m and up to 40 cm in diameter having low, rounded buttresses, bark surface initially smooth and hoop-marked, later rather rough and flaky, grey to reddish-brown.
*Leaves elliptical-oblong, (10-)20-33 cm × (3-)6-12 cm, densely pale golden-brown scaly below.
*Flowers in irregular racemes on older branches, petals up to 90 mm long, red, stamens free, opening by a slit.
*Fruit an ovoid to ellipsoid, pentangular capsule, up to 20 cm × 12 cm, dirty yellow, covered with slightly curved pyramidal soft spines 1-1.5 cm long.
*Seeds ellipsoid, up to 4 cm long, glossy brown, completely enclosed by a fleshy, yellow, sweet-smelling aril.


Cultivated trees start fruiting when 4-5 m tall. The aril comes nearest to the one of the real durian. The original habitat of the wild plants is the foothills of Borneo's central ranges; in Sarawak, it occurs locally on fertile clay-rich soils on undulating land in mixed dipterocarp forest. The heartwood is reddish-brown.
