Persicaria subsessilis (formerly known as Polygonum subsessile; Polygonaceae) 3:591

 

 
Persicaria subsessilis (bristly knotweed or bristly waterpepper) is a very rare, stout herb. It is only known from a couple of areas along the Tamar River. It has horizontal stems which curve up at the ends. The leaves are lanceolate to very narrow elliptic, 6-15cm long by 8-23mm wide. The spikes are elongate, 2-5cm by 5-8mm. A distinctive feature is the way that the leaves and often the stems are covered in erect, bristly hairs.
