The camphor tree ( Cinnamomum camphora ), also called camphor laurel is a plant belonging to the laurel family ( Lauraceae ).
Appearance, bark and leaf
The camphor tree growing reached as evergreen tree, the growth heights up to 30 meters and diameter at breast height ( DBH ) of about 3 meters. All parts smell strongly of camphor and also contain more or less a lot of camphor. The yellowish- brown bark peels off in irregular and longitudinal pieces. The bark of the branches terete is bluish and bare. The broadly ovate terminal buds have broadly oval to almost circular scales.
The alternate arranged on the branches leaves are divided into petiole and leaf blade. The bald, slender petiole is 2-3 cm long. Those with a length of 6 to 12 cm and a width from 2.5 to 5.5 cm ovate - elliptic leaf blade is almost leathery. The upper leaf surface is green to yellow- green yellow - green and glossy, the lower leaf surface, or yellow-green and frosted. Both leaf surfaces are bare or sparsely pubescent underside is as long as she is young.
Inflorescence and flower
The flowering period extends from April to May Page Constantly on a 2.5 to 4.5 cm inflorescence stem is a 3.5 to 7 cm large Rispige inflorescence. Inflorescence stem and inflorescence axis are bald or gray to yellow- brown fluffy hairy, especially at the nodes. The leafless flower stalks are 1-2 mm long. The hermaphrodite flowers are about 3 mm in size. The green- white or yellowish bracts are glabrous or hairy outside and fluffy inside densely hairy fluffy. The bloom are about 1 mm long, inverted - conical fused tube. The free portions of the bloom are elliptical having a length of about 2 mm. There are nine fertile, 2 mm long stamens with hairy fluffy stamens present. The egg-shaped with 1 mm length ovary is bald. The stylus has a length of about 1 mm.
The purple to almost black, fleshy fruit is egg-shaped with a diameter of 6 to 8 mm or almost spherical.

The fruits ripen from August to November.
