Heb. 'eshel (Genesis 21:33; 1 Samuel 22:6; 31:13, in the RSV; but in A.V., "grove," "tree"); Arab. asal. Seven species of this tree are found in Palestine. It is a "very graceful tree, with long feathery branches and tufts closely clad with the minutest of leaves, and surmounted in spring with spikes of beautiful pink blosoms, which seem to envelop the whole tree in one gauzy sheet of colour" (Tristram's Nat. Hist.).
