Rind is thin, pliable, tough. Flesh yellowish-white, sweet, clings tightly to the thick testa which separates from the seed. Flesh slightly glossy, tough, moderately sweet, and separates from the seed with a few particles of testa clinging to it. Air-layers are unsatisfactory, so it is rare in cultivation and expensive on the market. Much favored by Chinese because of its resemblance to the lychee.
Spines are thick and short.
Yellow-fruited rambutans are called 'Atjeh koonig' in Batavia. In Malaya, 'Rambutan gading' indicates a yellow type. One race with a partly free stone is known as 'rambutan lejang'. Burkill says that some rambutans are so sour that monkeys are reluctant to eat them.
