pill sedge
carex pilulifera latin

Pill sedge hangs on in its only known Haringey site, and tiny populations of cow-wheat, slender St. John's wort, wood anemone, and heath speedwell manage to survive, though they seldom flower.

Carex pilulifera was described by Carl Linnaeus in his 1753 work Species Plantarum, which marks the starting point of botanical nomenclature.
