Ata-ata can reach up to:

Height

25 m

Diameter

60 cm

Outer bark dark gray, smooth when young, wrinkled when mature; inner bark light colored
Leaves simple, alternate, oblong to oblong lanceolate, 10-25 cm long, 4-8 cm wide, shiny upper surface, paler lower surface, rounded base; 10-13 nerves each side
Flowers 4-merous, axillary, solitary, few-flowered racemes about 2 cm long.
Fruit globose, 3-4.5 cm wide, glabrous, yellowish when matured, 8-seeded; seeds ellipsoid 1.5-2cm, brown outside.
Lowland forest
ASSOCIATED VEGETATION: in semi-evergreen rainforest, Strombosia phililippinensis, Prunus grisea, Maranthes corymbosa, Celtis philippensis, Diospyros, pilosanthera, Alstonia scholaris, Palaquim luzoniense, Calopyllum blancoi, Ficus variegata, Parkia timoriana, Afzelia rhomboidea, Dracontomelon dao, D. edule, Lagerstroemia speciosa, Bischofia javanica, Ziziphus talanai, Pterocymbium tinctorium and Terminalia microcarpa (Fernando et al., 2008)
Primary Forest at low elevation
(In the absence of specific tree management practices for the species, practices for a relative Diospyros philippinensis could be used) SOWING. Germination media - Unsterilized garden soil + sand at 3:1 and 2:1 ratio. Seeds could be directly sown in plastic bags or pre-germinated in seedbeds at 4x3 cm spacing. Seeds could be recalcitrant like Diospyros philippinensis and therefore requires immediate sowing and short storage period. TRANSPLANTING AND CARE FOR SEEDLINGS. Seedlings are transplanted in plastic bags. Many seedlings reached the outplanting age of 3 months (11cm high) and 5 to 6 months after germination (7.5 cm high). Hardening treatments included gradual exposure to full sunlight for 2 to 4 months in Bicol and reduced watering for 2 months.
