Coriander
Easton's Dictionary
Heb. gad, (Ex. 16:31; Num. 11:7), seed to which the manna is likened in its form and colour. It is the Coriandrum sativum of botanists, an umbelliferous annual plant with a round stalk, about two feet high. It is widely cultivated in Eastern countries and in the south of Europe for the sake of its seeds, which are in the form of a little ball of the size of a peppercorn. They are used medicinally and as a spice. The Greek name of this plant is korion or koriannon, whence the name “coriander.”
