Properties. - The species of this highly important order are throughout pervaded by a warm and stimulant aromatic oil. Cinnamon is the dried bark of Cinnamomum Zeylanicum, of Ceylon, etc. Camphor is obtained from many trees of this order, but chiefly from Camphora officinarum, of Japan, China, etc. Cassia Bark, from Cinnamoinum aromaticum, of China. Persea gratissimn, ft tree of the W. Indies, yields a delicious fruit called the Avocado pear. Some of the following species are also moderately medicinal. The classic Laurel is Laurens nobilis of S. Europe.
