Reference: Bay Tree
Easton
named only in Ps 37:35, Authorized Version. The Hebrew word so rendered is ereh, which simply means "native born", i.e., a tree not transplanted, but growing on its native soil, and therefore luxuriantly. If the psalmist intended by this word to denote any particular tree, it may have been the evergreen bay laurel (Laurus nobilis), which is a native of Palestine. Instead of "like a green bay tree" in the Authorized Version, the Revised Version has, "like a green tree in its native soil."

Morish
From 'native born,' or that which springs up without transplanting. Ps 37:35 reads in the margin, 'tree that groweth in his own soil,' a striking emblem of the wicked spreading himself in his own earthly soil.
