「Tree」with「arrogant, impede, resist, evade.」Some sources say refers to the Chinese parasol tree, an invasive tree that「behaves arrogantly」by displacing other species. Some sources say refers to the lacquer tree in Japan. The lacquer tree is excellent for「impeding and resisting」insects that attempt to bore into the wood, not only by covering the bugs with thick, sticky goo that is in fact lacquer, but lacquer itself is the stuff that makes poison ivy poisonous, hence both insects and humans are often impeded in efforts to have their way with the wood. Note that the English name given to that toxin, urushiol, is derived from the Japanese word for lacquer tree resin (a different glyph 桼 however, that refers to the resin only, and not the whole tree).
　「Woody with poison sap」suggests an unchecked infection is present.「Woody with array of foot orifices」as a method of poisoning one's flow of woody sap back when no-longer-integrated feet were used for short-term rental items in dynastic China. As depicted in erotic Chinese art, men in dynastic China masturbated by wrapping no-longer-integrated feet around an erect penis ostensibly to lower the risk of contracting a sexually transmissible disease or infection that often occurred when performing coitus within some sort of mucous membrane system of a female service provider, and, to gain hand-control over the pressure applied to the foot meat surrounding a weakened penis that functioned as a living cockring.
　「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course)
