Shorea falciferoides ssp. falciferoides, also known as Yakal-yamban, is a dipterocarp species endemic to the Philippines.
A large tree that reaches about 30 meters in height, it has oblong to oblong-lanceolate coriaceous leaves, glabrous with a darker green adaxial side and a lighter and pubescent abaxial side. The leaf is 8.5 to 12 cm long and 3 to 6 cm wide, acuminate apex and rounded base. The secondary veins are arranged in pairs of 12 to 14, some veins have a domatia near the attachment point of the axis. The petiole is around 15 to 20 mm long with grayish pubescent hairs (twigs and flowering branches as well), the stipule is deciduous. The fruit is conical in shape and has the same gray pubescence that tapers into a persistent style, it reaches 7 to 8 mm in terms of diameter and 7 to 10 mm in height. It has 3 long calyx lobes which are 4 to 5 cm long and 10 to 12 mm wide, also displays the same grayish pubescence, are oblanceolate in its shape, and has 8 to 10 prominent longitudinal veins with an innumerable amount of cross veins. Much like Yakal-malibato (Shorea malibato) it also has shorter wings, these measure 2.5 to 3 cm long and 2 to 3 cm wide, with the same oblanceolate shape and number of longitudinal veins. It can be found in mixed dipterocarp forests that are seasonally wet or always moist up to 1000 masl. Known to fruit in May (Zambales). The trees are used for land reclamation and as shade for abaca. The wood is used for heavy construction such as posts and beams. Dipterocarp seeds are recalcitrant and easily lose viability when dried or stored long. After cutting the wings, the seeds should be planted in a potting medium as soon as possible. It can differentiated from other Yakal trees by the brown color under its leaves.
