Aegle marmelos, commonly known as bael (or bili or bhel), also Bengal quince,golden apple,Japanese bitter orange, or wood apple, is a species of tree native to India, Nepal, the Andaman and Nicobar Islands and Myanmar. It is present in Sri Lanka, Thailand and Malesia as a naturalized species. The tree is considered to be sacred by Hindus. Its fruits are used in traditional medicine and as a food throughout its range. The common name "wood apple" may also refer to Limonia acidissima.
Bael is the only member of the monotypic genus Aegle. It is a deciduous shrub or small to medium-sized tree, up to 13m tall with slender drooping branches and rather shabby crown.
The bark is pale brown or grayish, smooth or finely fissured and flaking, armed with long straight spines, 1.2-2.5 cm singly or in pairs, often with slimy sap oozing out from cut parts. The gum is also described as a clear, gummy sap, resembling gum arabic, which exudes from wounded branches and hangs down in long strands, becoming gradually solid. It is sweet at first taste and then irritating to the throat.
The leaf is trifoliate, alternate, each leaflet 5-14 x 2–6 cm, ovate with tapering or pointed tip and rounded base, untoothed or with shallow rounded teeth. Young leaves are pale green or pinkish, finely hairy while mature leaves are dark green and completely smooth. Each leaf has 4-12 pairs of side veins which are joined at margin. The end leaflet features a long stalk, 0.5–3 cm while side stalks are typically shorter than 0.2 cm.
The flowers are 1.5 to 2 cm, pale green or yellowish, sweetly scented, bisexual, in short drooping unbranched clusters at the end of twigs and leaf axils. They usually appear with young leaves. The calyx is flat with 4(5) small teeth. The four or five petals of 6–8 mm overlap in the bud. Many stamens have short filaments and pale brown, short style anthers. The ovary is bright green with inconspicuous disc.
The bael fruit typically has a diameter of between 5 and 12 cm. It is globose or slightly pear-shaped with a thick, hard rind and is not splitting upon ripening. The woody shell is smooth and green, gray until it is fully ripe when it turns yellow. Inside are 8 to 15 or 20 sections filled with aromatic orange pulp, each section with 6 (8) to 10 (15) flattened-oblong seeds each about 1 cm long, bearing woolly hairs and each enclosed in a sac of adhesive, transparent mucilage that solidifies on drying. The exact number of seeds varies in different publications.
