Poplar,
libneh. It was probably the white poplar (Populus alba) which Jacob employed: it was 'green' in the sense of being fresh, moist. The poplar affords a grateful shade from the heat of the sun and was therefore one of the trees chosen under which the Israelites burnt incense. Genesis 30:37; Hosea 4:13. Some judge the Hebrew word libneh to refer to the 'storax tree' (the styrax officinale) which also grows in Palestine.
