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 bulbosus - Bulbous Rush

Bulbous Rush is frequent on the granite uplands, the mid-Cornwall moors and the Lizard heaths, where it grows in streams, marshes and pools, as well as on seasonally-wet paths. Elsewhere it has a scattered distribution. There are three forms of the plant, two of which are known to occur in Cornwall; the terrestrial form (var. bulbosus ) and the very elongated aquatic form (var. fluitans (Lam.) Fr.). The latter may be found in strong flowing streams such as the Hayle river (SW53) and in some of the deep, moorland streams on Bodmin Moor. Bulbous Rush is also frequent on the Isles of Scilly.
