The Camphor tree

The tree is large with height of about 20 m (65 feet). The leaves are simple, alternate;blades entire but may have wavy margins, mostly ovate, 4-10 cm (1.5-4 in) long and 2-5 cm (0.8-2 in) broad, glossy green above, duller green below, with impressed glands below at major veins. Flowers are small, greenish white to cream, in loose panicles on branchlets of season;6 petaloid parts;12 stamen parts, usually 5-9 fertile stamens plus smaller sterile staminodes. The raw fruits are dark green, ovoid, dry, globose, and about 0.3 inch in diameter. They turn black on ripening. Every part of tree gives aroma of camphor due to presence of oil which is formed in the oil cells distributed in all parts of plant. These cells begin to form early in the growth organs, and are filled with yellow oil from which camphor is slowly deposited. The formation of camphor is brought about through the agency of an enzyme present in the growing pans of the tree particularly in the tissue within the cambium region.
