]. The bole is usually up to 30cm in diameter, occasionally to 80cm, with buttresses up to 2 metres tall[
This is a form of the much better known longan. Whilst the longan does not fruit well at low elevations in the tropics, this subspecies is much better adapted to the lowland tropics. The plant is sometimes cultivated as a fruit crop[
