Content
Description
Tree 10-36 m, 20-90 cm ø;
Branchlets initially densely yellowish brown to fulvous tomentose by adpressed stellate hairs and woolly or erect tuft-hairs, later subglabrous, dark greyish brown, with numerous minute lenticels;
Leaves coriaceous (10-)12-16(-24) by (4-)5-6(-10) cm (index (2-) 2½-(-3)), broadest at or below the middle;
Stipules narrowly ovate to linear, 5-10 by 2-3 mm.
Inflorescence male, androgynous or mixed, in dense, subterminal paniculate clusters, densely yellowish brown to fulvous stellate hairy;
Distribution
Asia-Tropical: Borneo present (Kalimantan present, Sabah present, Sarawak present); Jawa (Jawa present); Malaya (Peninsular Malaysia present, Singapore present); Philippines (Philippines present); Sumatera (Sumatera present), Idjen present, Kawi present, Luzon present, Mindoro present, Mts Ardjuno present, Penang present, Peninsular Siam present, Tengger present
Peninsular Siam (rare), in Malesia: Sumatra (scattered), Malay Peninsula (common; also in Penang and Singapore), Java (common in the western part, scattered in the central and eastern parts, eastwards to Mts Ardjuno, Kawi, Tengger and Idjen), Borneo (scattered in Sarawak, Kalimantan, and Sabah), Philippines (Luzon, Mindoro, rare).
Notes
The typical form of this species occurs at 1000-1500 m, and is characterized by the relatively thin leaves with a thin indumentum. Specimens from higher localities (Quercus pruinosa) usually have a somewhat smaller but thicker leaf with a thicker indumentum, and larger cupule and fruit than those of the typical form.
Specimens from below 500 m, formerly included in Quercus mappacea and Quercus grandifrons, have larger leaves with less indumentum, smaller cupule and fruit than those of L. sundaicus. The nervation, reticulation, the type of indumentum, fruit and cupule are, however, very similar in the whole series of specimens.
The Sumatran specimens, formerly recognized as Quercus lamponga, have smaller, almost glabrous leaves, but again the type of the cupule and fruit is the same.
