Nephelium ramboutan-ake

(Labill.) Leenh.

Sapindaceae


The Rambutan (Nephelium lappaceum) and the Pulasan (Nephelium ramboutan-ake) are very closely related. The only constant morphological difference between them is in the fruit appendages. In Nephelium lappaceum, the basal part of fruit appendage is small and inconspicuous and the upper part is thread-like and long; in Nephelium rambutan-ake, on the other hand, the basal part of fruit appendage is relatively large, triangular to ovoid, and tapering towards the short and broad, often thick and stiff apical part[
