What I have in mind:
Ouygender: a gender that is related to trees and wood.
Arborgender: a xenogender related to shade, trees, and silence.
Treei: an abinary/nonbinary xenogender related to any type of tree.
Rootgender: a gender that seems to “branch off” into several other genders but also containing a “core” gender.
Amlaine: a gender related to almas, the tree it comes from, bitter tastes, and freshness. Feels bitter, but still pleasant.
Fluctuatiogender: a gender that flows like the waves of the ocean, and strongly connected to wood and trees.
Silvigender: hat's refered to wood. [you] feel like [you] can understand trees, like [you] know what they feel and [you've] got this feeling [you've] got sap into [your] veins.
Lavsnøine: a gender related to snow on branches, trees, mountains covered in snow, glaciers, snowmen, snowballs, light fluffy snow, air, and winter. Feels cold, rocky, and hard.
If you don’t feel represented enough, feel free to coin a gender. :) - ap
