Carex Binervis (Paperback)

High Quality Content by WIKIPEDIA articles Carex binervis, the green-ribbed sedge, is a European species of sedge with an Atlantic distribution. It is found from Fennoscandia to the Iberian Peninsula, and occurs in heaths, moorland and other damp, acidic environments. It typically grows to a height of 15-120 cm (6-50 in), and has inflorescences comprising one male and several female spikes, each up to 45mm (1.8in) long. The utricles have two conspicuous green veins, which give rise to both the scientific name and the common name of the species. In the vegetative state, it closely resembles C.bigelowii, a species that usually grows at higher altitude. C.binervis was first described by James Edward Smith in 1800, and is classified in Carex sect. Spirostachyae; several hybrids with other Carex species are known.
