prostrata (Creeping Knotweed) is a low growing herb found on the
banks of streams and in ditches. It is not clear whether it is native
or a weed. The leaves are narrow ovate, about
1-4cm long by 4-7mm wide, and quite hairy. The ochreas (the
sheathing scales) are distinctive in being extended into a green,
spreading toothed limb. The spike is shortly cylindrical, up to 4cm long and
4-7mm wide. |
