Field Notes
The plant that we observed and studied was the Japanese Knotweed. The leaves to the plant are smooth along with the sides and the surface is simple, and next to the leaves are the seasonal white flowers with seeds in them (as shown in the sketch) that are connected to the hollow stem. On the bamboo stem are large markings, where the markings are the insides of the bamboo stem the bamboo stops and blocks off a section.

The main stems of the plant was hollow and had the same structure of the bamboo showed on our plant identification sheet, the insides stopped at some spots and had bumps where they stopped, just like bamboo has.
