寄生植物？ Parasitic plant?

写真は家の近くのクヌギ（どんぐり）の木の幹の間に育っているモミジの木ですが、私には寄生植物に見えます。

但し、寄生植物には以下の定義があり、その種類も限られているようです。

定義：宿主（寄主）となる植物の幹や枝、根に自分の根を食い込ませて、宿主となった植物が光合成などで稼いだ栄養分を吸収（横取り）している時、その植物を寄生植物と呼びます。

種類：写真参照

The photo shows a maple tree growing between the trunks of a sawtooth oak (acorn) tree near my house, which looks like a parasitic plant to me.

However, parasitic plants have the following definitions and seem to be limited in their types.

Definition: A plant is called a parasitic plant when it is able to absorb (intercept) nutrients earned by the host plant through photosynthesis, etc. by inserting its own roots into the trunk, branches, or roots of the host (parasite) plant.

Types: See photo
