Nephelium ramboutan-ake

Nephelium ramboutan-ake (Labill.) P. W. Leenhouts (syn: Euphoria longana Bl.; Euphoria ramboutan-ake Labill.; Nephelium griffithianum Kurz; Nephelium intermedium Radlk.; Nephelium mutabile Bl.; Nephelium philippinense Monsalud et al.);  
peninsular Malaysia (Penang, Kelantan, Terengganu, Perak, Pahang, Selangor, Melaka), +Singapore, Java, Borneo, India (Assam, Arunachal Pradesh, Tripura, Meghalaya), Myanmar [Burma], Sumatra, Philippines (Luzon, Mindoro, Leyte, Samar, Mindanao, Basilan), Palawan, Moluccas (Sula Arch.), Thailand, Costa Rica (I) as per Catalogue of Life;
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.
The only ‘good’ difference between N. lappaceum and N. ramboutan-ake is in the fruit appendages. In the former they have a small and inconspicuous basal part and a long, filiform upper part, whereas in the latter the basal part is relatively large, triangular to ovate in shape, and tapering into a short and broad, often thick and stiff apical part.
