Cinnamomum camphora
What are the morphological characteristics of this plant?
Cinnamomum camphora has evergreen leaves that are opposite, elliptical to lanceolate in shape, and possess a distinctively glossy, dark green upper surface with a paler underside. The leaf margins are typically entire or slightly undulate, and the texture feels somewhat leathery to the touch. Its bark is characteristically smooth and greyish when young, but it becomes deeply fissured and scaly as the tree matures. The plant produces small, inconspicuous yellowish-green flowers arranged in axillary panicles. Following pollination, it develops small, globose drupes that transition from green to a bright red color when ripe.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, specifically spanning from southern China and Taiwan through Vietnam, Thailand, Malaysia, and Indonesia. It flourishes in the humid climates of the Indochina peninsula and the various archipelagos of the Malay Archipelago. Its natural range is primarily concentrated within low-altitude rainforests and moist evergreen forests. Due to its historical use in traditional medicine and fragrance, it has been introduced to other tropical territories around the world. This widespread distribution is supported by the species' ability to thrive in high humidity and warm temperatures.
