Calamus, Song of Solomon 4:14, Ezekiel 27:19, or Sweet Calamus, Exodus 30:23, or Sweet Cane, Isaiah 43:24, Jeremiah 6:20. These are probably names for the same plant. It seems to have been an aromatic reed brought "from a far country." Lemon-grass is "a plant of remarkable fragrance and a native of Central India, where it is used to mix with ointments, on account of the delicacy of its odor." Calamus may have been a species of this.
