Nephelium subfalcatum


Tree, up to 35 m high, dbh up to 60 cm, with up to 2 m high buttresses. Leaves 1-foli-olate to 5-jugate; Inflorescences axillary, pseudoterminal, or terminal. Sepals variably but mostly rather high up connate, 1-2 mm long. Petals absent. Stamens (6-)8. Ovary 2-celled. Fruits ellipsoid, 3.25-3.75 by 2.5 cm, glabrous, ± densely set with strap-shaped to filiform, curved, up to c. 15 mm long, appendages, bulbous to triangular at the base, confluent or not;


Asia-Tropical: Borneo present; Malaya (Peninsular Malaysia present); Sumatera (Sumatera present)
Malesia: Sumatra, Malay Peninsula, Borneo.


1. At first sight, the material from Borneo seems rather different from that of Malaya and Sumatra. The main differences are that the Borne-an material is more glabrous, the margin of the petiolules is not swollen, the apex of the leaflets is long-, slender-, and acute-acuminate, and the fruit appendages are somewhat longer. But these differences are not sharp, they do not hold for all Bor-nean specimens, and KEP FRI 13331, from Malaya agrees nearly completely with the Bornean form. Accordingly, a subdivision seems unwarranted.
2. The leaves of the present species resemble in shape strongly N. laurinum; for differences, see under that species.
3. The Bornean form of N. subfalcatum in particular comes close to N. uncinatum; for differences, see there.
