Larches are medium to large trees of the genus Larix. Scientists debate the finer points of the group’s interrelationships and classification, but most recognize about 10 to 15 species.
Examination of the needles helps to distinguish fir trees from lookalikes. Fir needles are generally soft to the touch, flat in cross section and attach to the branch via suction-cup-like structures
