|Easton's Bible Dictionary|
Occurs only in Job 30:4 (R.V., "saltwort"). The word so rendered (malluah, from melah, "salt") most probably denotes the Atriplex halimus of Linnaeus, a species of sea purslane found on the shores of the Dead Sea, as also of the Mediterranean, and in salt marshes. It is a tall shrubby orach, growing to the height sometimes of 10 feet. Its buds and leaves, with those of other saline plants, are eaten by the poor in Palestine.
Noah Webster's Dictionary
(n.) A genus of plants (Malva) having mucilaginous qualities. See Malvaceous.
