Thumb print mark on leaf and the ocrea are indicated. The leaf sheath
gives the Buckwheat Family the alternate name of knotweeds because of the
'swelling' at the joints along the stem which are thought of as 'knots'.
Also polygonium means many knees or joints which refers to the swellings
along the stem at the nodes.
