The following is the results of your search for willows.
Willows: 1. Heb. 'arabim
(Leviticus 23:40; Job 40:22; Isaiah 15:7; 44:3,4; Psalms 137:1,2)
This was supposed to be the weeping willow, called by Linnaeus
Salix Babylonica, from the reference in
(Psalms 137:1-2) This
tree is frequently found "on the coast, overhanging wells and
pools. There is a conspicuous tree of this species over a pond
in the plain of Acre, and others on the Phoenician plain." There
are several species of the salix in Palestine, but it is not
indigenous to Babylonia, nor was it cultivated there. Some are
of opinion that the tree intended is the tamarisk or poplar.
2. Heb. tzaphtzaphah
(Ezekiel 17:5) called by the Arabs the safsaf, the
general name for the willow. This may be the Salix AEgyptica of
naturalists. Tristram thinks that by the "willow by the
water-courses," the Nerium oleander, the rose-bay oleander, is
meant. He says, "It fringes the Upper Jordan, dipping its wavy
crown of red into the spray in the rapids under Hermon, and is
nutured by the oozy marshes in the Lower Jordan nearly as far as
to Jericho...On the Arnon, on the Jabbok, and the Yarmuk it
forms a continuous fringe. In many of the streams of Moab it
forms a complete screen, which the sun's rays can never
penetrate to evaporate the precious moisture. The wild boar lies
safely ensconced under its impervious cover."
