Stick is a colloquial term for both framing lumber (timber) and a "timber tree" (a tree trunk good for using as lumber (timber)); thus, the names "stick and platform", "stick and frame", "stick and box", or simply stick framing.
The term "stick" is used as a colloquial name for both the timber used in building frames and the actual timber trees that provide this material. This leads to names such as "stick and platform", "stick and frame", "stick and box", or just "stick framing".
