PINE RELATIVE is a term used to describe two types of trees, the LARCH (5 letters) and the FIR (3 letters). Both trees are conifers, meaning they produce cones and have needle-like leaves. The LARCH is a deciduous conifer, meaning it loses its needles in the winter, while the FIR is an evergreen conifer, meaning it keeps its needles year-round. Both trees are related to the Pine tree, hence the term PINE RELATIVE.
