Styrax benzoin Dry ander

Styrax benzoin Dryander, Phil. Trans. 77:308, t.12. 1787.—Perkins, in Das Pflanz., 30:60. 1907.

DESCRIPTION (based on Wilder 1238).—Tree, 10 m high. Young growth, inflorescence, perianth and fruit greenish gray, stellate-tomentose. Leaves alternate, to 12 × 4 cm, entire or somewhat irregularly toothed, glabrous above, white stellate-tomentose below. Panicles axillary, loose, to 6 cm long, about 12-flowered. Calyx cup-shaped, 3 mm long, barely 4-toothed. Petals 4, valvate, linear-oblong, 5 mm long, obtuse. Fruit globose, 13 mm in diameter, 1-celled, thick-walled. Seeds basal, globose, 6 mm long.

The specimen checks with Perkins' description except that the perianth, in part at least, is 4-merous instead of 5-merous, and the petals are very short.

Styrax benzoin

provided by wikipedia EN

Styrax benzoin is a species of tree native to Sumatra in Indonesia. Common names for the tree include gum benjamin tree, loban (in Arabic), kemenyan (in Indonesia and Malaysia), onycha, and Sumatra benzoin tree.[1]

Distribution

It is a common member of the forests of Sumatra, Indonesia, where it grows to about 12-30 meters in height. Styrax benzoin can live 70-100 years. It is unknown how it came to Sumatra. Scientists says styrax benzoin from Sumatra has the best quality.

The process of tapping and harvesting frankincense takes one year. The styrax benzoin tree trunk is cut slightly, so that the white styrax sap will appear from the skin. After 4-6 months of the styrax sap hardens on the tree trunks at which point the sap can be harvested.

The sap that has been harvested is not clean and is dried for 3 to 6 months to remove impurities. After the sap has dried, it is ready for export.

You can find incense trees in several countries in Southeast Asia, such as Malaysia, Laos, Vietnam and Indonesia. The tree can thrive in mountainous areas and cold temperatures with high rainfall. Styrax trees can also grow in lowland areas with hot temperatures but these do not produce good quality styrax sap.[2]

Cultivation

Styrax benzoin is cultivated as a main source of benzoin resin in Indonesia. It is also grown as an ornamental tree for shade in West Africa.
