2. Pentacme sp. 
Leaves broadly oblong, shortly and abruptly acuminate, base 'rounded ; 
stipules 2 to 3 cm long, 7 to 8 mm wide, lanceolate or oblanceolate ; 
secondary nerves about 15 pairs. Young shoots, petioles and underside 
of leaves covered with a grayish tomentum. Wood soft and white, with 
much the same structure as that of P. contorta but finer-grained. Bark 
dark and fissured. A tree of the low flat forest near the beach. 
Luzon, Province of Tayabas, For. Bur. 10383 Curran. 
This form seems to show some points of resemblance to Pentacme siamensis 
Kurz. 
5. SHOREA Eoxb. 
Large resinous trees ; stipules in a few species large and persistent, in 
most small and early deciduous. Leaves chartaceous or coriaceous; sec- 
ondary nerves prominent; tertiary nerves mostly parallel. Flowers as 
a rule in unilateral spikes or racemes, these distichous and regularly 
alternating on the branches of large axillary and terminal panicles. Each 
flower subtended by two, mostly deciduous, in a few species persistent 
and conspicuous, bracts. Sepals strongly imbricate, always hairy outside, 
and often inside also, on the margin of a broad obconical receptacle. 
Petals oblong, rarely ovate-oblong, hairy on the outside. Stamens gen- 
erally 15, in some species more. Anther-cells generally equal ; connective 
prolonged into a pointed appendage, generally longer than the anther, 
sometimes short or wanting. Segments of fruiting calyx with their broad 
bases tightly enclosing the fruit, the three outer ones generally longer 
than the others and much longer than the fruit. 
Pipe seed generally without albumen. Cotyledons thick, fleshy, gen- 
erally both bifid to their base, that is to the point where they are attached 
to the apex of the hypocotyl (radicle) or to the petioles. 
Pith with 3 to 30 perimedullary resin-canals, with now small now wide 
lumen. The . structure of the petiole is various; usually it shows the 
characteristic form ; viz., a semicircle of 7 to 9 isolated vascular bundles 
with alternating resin-canals and a central bundle-system without reSin- 
canals; in other species there is found a central bundle system with no 
or 1 to 3 resin-canals. 
The largest genus in the family, with more than 90 species, with 14 
species in the Philippines. Of our Philippine species four, S. balangeran, 
8. eximict, 8. squamata , and S. teysmanniana are extra-Philippine in 
distribution.
