Cinnamomum burmannii, also known as Indonesian Cinnamon, Padang Cassia, or Korintje, is one of several plants in the genus Cinnamomum whose bark is sold as the spice cinnamon. The most common and cheapest type of cinnamon in the US is made from powdered Cinnamomum burmannii. Cinnamomum burmannii oil contains no eugenol. It is also sold as quills of one layer.
Cinnamomum burmannii is an evergreen tree growing up to 7 m in height with aromatic bark and smooth, angular branches. The leaves are glossy green, oval, and about 10 centimetres (3.9 in) long and 3–4 centimetres (1.2–1.6 in) wide. Small yellow flowers will bloom in early summer, and produce a dark berry.
Cinnamomum burmanii is native to Southeast Asia and Indonesia. It is normally found in West Sumatra near the city of Padang. Cinnamomum burmanii grows in hot wet, tropical climates, and is an introduced species in parts of the subtropical world, particularly in Hawaiʻi, where it is naturalized and invasive. It was introduced to Hawaiʻi from Asia in 1934 as a crop plant.
