Persicaria laxiflora
(Map updated: March 2008)
 

This is similar to Persicaria hydropiper (water-pepper) in appearance, and grows in similar situations, but is much rarer. It can be separated from it by the erect flower spike (not drooping) and an absence of glands, as well as having no peppery taste.

Mostly about Lough Erne, Lough Neagh and a few other lakes.

Also known as Polygonum mite.

All names: Persicaria laxiflora (Weihe) Opiz; Polygonum mite Schrank; Polygonum mitis Gilib.; Polygonum laxiflorum Weihe
