Calamus

the Latin for cane, Hebrew "Kaneh", mentioned (Ex. 30:23) as one
of the ingredients in the holy anointing oil, one of the sweet
scents (Cant. 4:14), and among the articles sold in the markets
of Tyre (Ezek. 27:19). The word designates an Oriental plant
called the "sweet flag," the Acorus calamus of Linnaeus. It is
elsewhere called "sweet cane" (Isa. 43:24; Jer. 6:20). It has an
aromatic smell, and when its knotted stalk is cut and dried and
reduced to powder, it forms an ingredient in the most precious
perfumes. It was not a native of Israel, but was imported
from Arabia Felix or from India. It was probably that which is
now known in India by the name of "lemon grass" or "ginger
grass," the Andropogon schoenanthus. (See CANE T0000710.)
