I went to Wick River to see what was growing: the "Wick Sedge" (Carex recta) is easily seen just now. The flowers are prominent - later they will be overtopped by the leaves and obscured. The plant is very rare, with its world population being in the Wick River, the Beauly River and some below Carbisdale and maybe a bit in the east of the USA. There is a lot of it at Wick, several acres around the viewing platform on the north bank. It was originally discovered in 1886 by Mr Grant the then editor of the Groat and a good botanist. Nowadays it has been renamed "The Estuarine Sedge" by the powers that be!
