Flora of Cornwall (1999)

The descriptive text, below the map, is from the Flora of Cornwall (1999), which was a Tetrad Atlas (the maps had 2km square dots or Tetrads). The map on this web page depicts the plant's distribution at the 1km square scale and shows the records made pre-2000 which were used in the 1999 Flora and those made since.

Juncus capitatus - Dwarf Rush

Dwarf Rush is currently confined in Cornwall to the Lizard Peninsula, and here virtually only on the serpentine. It was once known from outside the Lizard; at Chy-an-hal Moor ( SW42P) and from moorland near Sennen (SW32M), both in Penwith, and there is an unconfirmed nineteenth century record for St. Mary's, Isles of Scilly. Normally associated with low rock outcrops, it grows around the edges of these where there is some groundwater flow. A Red Data Book rush, it is still fairly frequent on the Lizard and can usually be seen each year around serpentine outcrops near Kynance Gate (SW61W).
