Gen info
- Fabaceae or Leguminosae, commonly known as the legume pea, or bean family, is a large and agriculturally important family of flowering plants that includes trees, shrubs, and perennial or annual herbaceous plants. It is widely distributed and is the third largest land plant family, behind only Orchidaceae and Asteraceae, with about 765 genera and nearly 20,000 known species. (6)
- Pericopsis is a genus of flowering plants in the legume family, Fabaceae. The trees in the genus provide excellent timber, which is used as a substitute for teak.
- Pericopsis mooniana, the nadu wood or nedun tree, is a species of legume in the family Fabaceae; a tree threatened by habitat loss.

Botany
• Medium-sized to fairly large trees, up to 40 m tall, with bole straight or twisted, branchless for up to 20 m but often less, up to 80(—100) cm in diameter, shallowly grooved or slightly fluted at base; bark soft and thin, reddish, flaking in thin plates. Leaves alternate, imparipinnate, 5—8-foliolate; leaflets alternate or rarely subopposite, ovate to elliptical, 4—9 cm 2.5—5 cm, rounded at base, acute to broadly acuminate at the top, glabrous, with about 7 pairs of secondary veins; stipules early caducous, stipels minute or absent. Inflorescence racemose or paniculate, axillary or terminal, bracts and bracteoles minute, very early caducous. Flowers bisexual, about 2 cm long; calyx bell-shaped, about 15 mm long, appressed pubescent outside, tomentellous inside, with 5 acute lobes, two slightly shorter than the other three, and connate for most of their length; corolla papilionaceous, keel petals partly connate, wings auriculate, glabrous, dark purple; stamens 10, equal, free, anthers small, ellipsoid to oblong, dorsifixed; ovary stipitate, 1—6-ovuled, pubescent along the margin, style with a hooked apex and a small terminal stigma; disk present at base of ovary. Fruit a slightly woody, oblong pod, flat, indehiscent, stipitate with a narrow base, beaked at the tip, winged along margin, glabrous, sometimes constricted near the middle. Seeds large, flat, rounded to elliptical, reddish-brown, with apical orbicular hilum. Seedling with epigeal germination. (PROSEA) (3)

• Tall tree; young stems pubescent; leaves imparipinnate, 5-8-foliate, the axis glabrous, about 10-16 cm long; leaflets about 4-9 cm long and 2.5-5 cm broad. Inflorescences racemose or paniculate, about 6-10 cm long. Flowers about 2 cm long; petals blackish-purple. Fruit 1-6 seeded, 6-15 cm long; seeds reddish-brown, compressed, about 15 mm long, 7-8 mm wide and 4 mm thick, hilum orbicular, about 1 mm in diameter.

Distribution
- Native to the Philippines. (1) (2)
- In Homonhon; in Mindanao: Zamboanga del Sur.
- Lowland forests near the sea. 0-100 m.
- Vulnerable due to heavy timber exploitation and habitat loss, commercial extraction of volatile oils from wood.
- Also native to Borneo, Caroline Is., Lesser Sunda Is., Malaya, Myanmar, New Guinea, Sri Lanka, Sulawesi, Sumatera. (2)
