74E896752F7B86EF4DB19C05EC766D19.taxon	description	Description. Small-medium sized tree, up to 15 m tall. Bark smooth to slightly rough grey-green, with superficial horizontal lines. Sapwood white to yellow, with inner bark ridges forming light brown longitudinal slits in sapwood surface. Branches dark brown to grey brown, mostly glabrous, densely lenticellate; young twigs, leaf buds and old fruits with short, soft (occasionally long) gray indumentum. Leaf buds tiny and terminal buds solitary. Leaves simple; lamina elliptic to oblanceolate with (strongly) acuminate tip, 11.0 - 22.3 x 4.4 - 7.1 cm. Margin entire. Leaves often with slightly asymmetric lamina. Leaf apex acuminate to strongly acuminate, leaf base cuneate to slightly attenuate. Both surfaces generally glabrous except emerging leaf buds, terminal shoots and young leaves, which have soft grey indumentum. Young leaves light green, but turning dark green above and glaucous below when older. Venation. Pinnately veined; secondary venation discretely anastomosing near the leaf margin. Pairs of secondary veins 9 - 13, slightly raised and clearly visible on underside of leaf. Peduncles carrying fruits 5 - 11 cm long, up to 1 cm thick at the base, glabrescent, grey-brown and densely lenticellate. Male and female inflorescences not seen. Infructescence a woody spike, terminal, up to 15 - 21 cm long. Fruits sessile on thick woody peduncle, closely pressed against each other, but walls of individual units not fused. Number of fruits per infructescence very variable, ranging from 9 - 20 units. Acorn. Orbicular, globose, 2.7 - 3.4 by 2.9 - 3.5 cm (including cupule) and covered with glabrous, semi-concentric interlocking ridges when young, which transform over time into ridges with irregularly placed scales. Cupule nearly completely enclosing the nut, indehiscent, but showing small cracks when mature; fruit wall up to 4 - 6 mm thick, apical pore very small, 1 - 4 mm wide, exposing the persistent punctiform styles (3) and a tiny fraction of vestigial exocarp. Young cupule walls light green, ridges light to dark brown. Old cupule walls turning light brown to yellow-brown and pubescent with short (occasionally long), greyish-yellow indumentum. Nut 1 in each cupule, ball shaped, globose, 2.4 - 2.9 by 2.6 - 3.0 cm. Up to 95 % of surface area of the nut made up of scar area (receptacle tissue), upper 5 % of surface area of the nut slightly raised and made up of vestigial exocarp layer. Nut scar pale yellow-whitish, tiny exocarp layer light brown. Scar area covered with deep groves and red-brown to purplish vein-like lines, stretching down to the base of the nut. Up to 5 / 6 of the scar area of the young nut (from the base upward) covered with dotted pattern of small depressions. Cotyledons black when dried.	en	Strijk, Joeri S., Sirimongkol, Sukontip, Rueangruea, Sukid, Ritphet, Nikom, Chamchumroon, Voradol (2014): Lithocarpus orbicarpus (Fagaceae), a new species of Stone Oak from Phang Nga province, Thailand.

74E896752F7B86EF4DB19C05EC766D19.taxon	distribution	Distribution. This species is only known from Thailand, and has not been recorded outside Ton Pariwat Wildlife Sanctuary, Mueang district, Phang Nga Province. During our field survey, we found only one individual tree, located on a gentle sloping section of closed dense forest. Additional survey work will have to be undertaken to determine the actual population size of this species within the wildlife sanctuary.	en	Strijk, Joeri S., Sirimongkol, Sukontip, Rueangruea, Sukid, Ritphet, Nikom, Chamchumroon, Voradol (2014): Lithocarpus orbicarpus (Fagaceae), a new species of Stone Oak from Phang Nga province, Thailand.
