What is "dryobalanops aromatica"

Camphor \Cam"phor\ (k[a^]m"f[~e]r), n. [OE. camfere, F. camphre (cf. It. canfora, Sp. camfora, alcanfor, LL. canfora, camphora, NGr. kafoyra`), fr. Ar. k[=a]f[=u]r, prob. fr. Skr. karp[=u]ra.]

1. A tough, white, aromatic resin, or gum, obtained from different species of the Laurus family, esp. from Cinnamomum camphara (the Laurus camphora of Linn[ae]us.). Camphor, C10H16O, is volatile and fragrant, and is used in medicine as a diaphoretic, a stimulant, or sedative.

2. originally, a gum resembling ordinary camphor, obtained from a tree ( Dryobalanops aromatica formerly Dryobalanops camphora) growing in Sumatra and Borneo; now applied to its main constituent, a terpene alcohol obtainable as a white solid C10H18O, called also Borneo camphor, Malay camphor, Malayan camphor, camphor of Borneo, Sumatra camphor, bornyl alcohol, camphol, and borneol. The isomer from Dryobalanops is dextrorotatory; the levoratatory form is obtainable from other species of plants, and the racemic mixture may be obtained by reduction of camphor. It is used in perfumery, and for manufacture of its esters. See Borneol.

   Note: The name camphor is also applied to a number of bodies of similar appearance and properties, as cedar camphor, obtained from the red or pencil cedar ( Juniperus Virginiana), and peppermint camphor, or menthol, obtained from the oil of peppermint.

   Camphor oil (Chem.), name variously given to certain oil-like products, obtained especially from the camphor tree.

   Camphor tree, a large evergreen tree ( Cinnamomum Camphora) with lax, smooth branches and shining triple-nerved lanceolate leaves, probably native in China, but now cultivated in most warm countries. Camphor is collected by a process of steaming the chips of the wood and subliming the product.

Dryobalanops aromatica, commonly known as Borneo camphor, camphor tree, Malay camphor, or Sumatran camphor, is a species of plant in the Dipterocarpaceae family. The species name aromatica is derived from Latin (aromaticus = spice-like) and refers to the smell of the dammar (resin). This species was one of the main sources of camphor and attracted early Arab traders to Borneo, at that time being worth more than gold, and used for incense and perfumes.

It is found in Sumatra, Peninsular Malaysia and Borneo.

It is a large emergent tree, up to 65 m or even 75 m tall, found in mixed dipterocarp forests on deep humic yellow sandy soils. It is a heavy hardwood sold under the trade names of Kapur. It is recorded from at least two protected areas ( Lambir and Gunung Mulu National Parks).

Bergenin, malaysianol A, laevifonol, ampelopsin E, α-viniferin, ε-viniferin and diptoindonesin A can be isolated from the stem bark of D. aromatica.

D. aromatica is one of several tree species known to exhibit a behavior called crown shyness.
