Xanthostemon philippinensis, commonly known as Bagoadlau, is endemic to the Philippines.
A tree that averages at 20 meters tall, mostly smooth with the exception of its young branches. Reddish-brown and terete branches. Leaves are arranged alternately and are localized near the end of young branches. Leaves shaped elliptically to obovate-elliptical with a leathery texture typically 4 to 7 cm long and 2.5 to 3.5 cm wide. Leaf apex round while leaf base is decurrent-acuminate, it has around 10 lateral veins on each side of the midrib and 1 cm long petiole. Inflorescence is racemose and terminal with yellow florets with 1 cm long pedicels. 5 mm long cup-shaped calyx tube that is also 8 mm with minutely ciliate margins. The petals are sub-orbicular and are 5 per floret, around 7 to 8 mm in diameter. Perianth-tube is lined with a prominent disc that projects beyond the insertion points of the filaments, around 8 mm in diameter. Stamens typically around 24 in each floret, and 15 mm in length. Superior ovary that is ovoid, 3 celled, and with a 2 cm long style. The wood is one of the hardest of the ironwood trees and is used for construction. It is also a phytoaccumulator, meaning it intakes nickel and magnesium within the soil.
