Nephelium cuspidatum

Description

Tree, up to 40 m high, dbh up to 80 cm, sometimes with small buttresses, rarely a shrub. Leaves (1-) 2-9(-13)-jugate; Inflorescences mostly in the upper leaf axils, together pseudoterminal, sometimes terminal, also rami- or cauliflorous, often long pendulous racemes or spikes. Sepals hardly to up to halfway connate, 1.1-2.5 mm long. Petal' mostly absent, if present often reduced in number. Stamens (4-)7 or 8 (or 9). Ovary 2-celled. Fruits ellipsoid to sometimes globular, 2-4 by 2-3 cm, glabrous or sometimes slightly hairy at the tip of the appendages, mostl y densely set with appendages, those filiform to narrowly strap-shaped and up to 2 cm long, or sometimes ligulate and 5-6 mm long, straight or often curved or curled, at base globular, pyramidal, or triangular and in the latter case often connate;

Distribution

Asia-Tropical: Borneo present; Cambodia (Cambodia present); Malaya (Peninsular Malaysia present); Philippines (Philippines present); Sumatera (Sumatera present); Thailand (Thailand present); Vietnam (Vietnam present), Burma present, Palawan present, W Java present
Burma, Thailand, Cambodia, Vietnam, and Malesia: Sumatra, Malay Peninsula, Borneo, W Java, and Philippines (Palawan).

Uses

Locally cultivated as a fruit tree. The wood is sometimes used for constructions but is not of a very good quality. See Burkill, Dict. Econ. Prod. Malay Penins. (1935) 1544, 1548; Heyne, Nutt. Pl. Indon. ed. 3 (1950) 997.

Notes

In the delimitation presently accepted N. cuspidatum is a rather complex species. The extremes included, e.g. N. robustum and N. dasyneu-rum, seem very different. However, it appears that the common and widespread N. eriopetalum is connected directly or indirectly with all other forms and that either no separation is possible at all, or only on unimportant (e.g. the coarsely reticulate venatlon of N. robustum and to a lesser degree of N. bassacense, versus the very minute reticulum of the other forms) or untrustworthy (e.g. hairiness or the] degree of reduction of the corolla) characters. As far as could be seen from the field labels there are no clear ecological differences either; all but Nueriopetalum are rather restricted geographically.
In order to enhance the accessibility of the group as a whole a subdivision into six varieties was made, two of which have been divided into subvarieties.
