A tree (木) named by its sound — 松 is the pine, the evergreen that holds its needles through winter. 公 gōng carries the sound, worn to sōng. The "loosen, relax" sense you meet in 松弛 belongs to 鬆, written elsewhere; this 松 stays the tree.

一棵樹(木),雪壓下來,針葉還綠著——松。
A tree (木) under the snow, its needles still green — the pine.
