Bong is a small to medium-sized tree, about 10 m-25 m tall and 10 cm-45 cm in
DBH. Bong khao (white) and bong daeng (red) are named after their respective colours of sticky sap and inner bark and leafstalk (1 cm-2 cm). The grey bark is 0.5 cm thick. Bong khao leaves are rounded, egg-shaped, 12 cm-14 cm long and 6 cm-7.5 cm wide; bong daeng leaves are elongated, 15 cm-25 cm long and 4 cm-6 cm wide. Flowers grow in clusters while the fleshy fruit has a single seed c. 0.5 cm in diameter. Taxonomy is not clear among the bong species. Some species with the bong name belong to other families and do not produce bong bark. The various other species producing bong bark are: Persea villosa (bong khao nhai); P. umbelliflora (Bl.) Kostern. or Notaphoebe umbelliflora Bl. (bong khao); Actinodaphne cochinchinensis (bong daeng noi); Machilus chinensis (bong khao noi); Litsea monopetala Pers. (bong khao, bong mee).
