Castanopsis andersonii Gamble
Tree with buttresses and smooth bark. Twigs sparsely lenticullate. Stipules linear, 3-7 mm long but
dropped early. Petiole with distinctly swollen base, 1-2.5 cm long. Leaves elongate with widest point
slightly above the middle, ca. 12 by 5 cm, with 10-15 secondary veins. Fruits splitting in four parts,
subsessile, sometimes distinctly 4-lobed, felty hairy and with densely set, sturdy somewhat recurved
spines (4-15 mm long) which are placed solitary or in bundles.
Tree, 10-24 m by 30-60 cm diameter; buttresses up to 1.2 m tall, 5 cm thick; bark smooth, grey.
Branchlets initially tomentellous or glabrous; slender to rather sturdy, sparsely lenticellate; terminal
bud ovoid-globose or ellipsoid, 3-5 by 2-3 mm, scales ovate-acute. Stipules linear, 3-7 mm long,
very early caducous. Leaves thick-coriaceous, (6-)8-12(-18) by (1-)3-5(-7) cm (index 2.2-3),
widest about the middle to rarely below; base attenuate to rounded, and acute, apex acute to
0.5¡ª1 cm acuminate; glabrous, mostly concolorous, glossy above, dull beneath; midrib strongly
prominent beneath, slightly so above; nerves 10-15 pairs, c. prominent beneath, flattish above,
at an angle of 45-70 degrees, parallel, ascending, arcuating towards the margin; reticulation fine, dense,
more or less regularly scalariform, obscure on both surfaces; petiole 1-2.5 cm, adaxially flat to
deeply sulcate. Male rachis 10-17 cm, 1-2 mm diameter; bracts and bracteoles ovate-acute, 1 by 1 mm;
male flowers in clusters of 3-7, perianth lobes membranous, 0.8-1 by 0.5-0.7 mm, densely hairy outside;
stamens 12, filaments 2 mm long, anthers 0.2 mm long, pistillode 1-1.5 mm diameter. Female or androgynous
rachis 10-15 cm, 2-3 mm diameter, bracts and bracteoles ovate-acute, 1 by 1 mm; female flowers in
clusters of 3, perianth lobes 0.7-1 by 0.5-0.7 mm, membranous, densely hairy; staminodes 12, rudimentary,
styles 3, cylindrical-conical, 1-1.5 mm. Young infructescence: rachis 20-25 cm, 3 mm diameter.
Young cupule obovoid-globose, the segments between the 4 sutures covered with spines. Ripe
cupules scattered along the rachis, (sub)sessile, obovoid-globose, sometimes distinctly 4-lobed,
3/4-4 cm through; wall 1.5 mm thick, inside with long, ferruginous, silky hairs, outside more or
less densely hoary-puberulous or felty, rather densely set with sturdy somewhat recurved spines
4-15 mm long, solitary or in bundles, hairy with glabrous top; dehiscence into 4 segments or irregular.
Fruits 2-3 per cupule, ovoid-conical, 1-1.5 cm through, scar occupying 0.25-0.7 part, flat convex;
free part of the wall with brownish silky tomentum. [from Flora Malesiana]
