There are two sub-species of Carex divulsa: Grey Sedge (Carex divulsa ssp. divulsa) and Leer's Sedge (Carex divulsa ssp. leersii) which Clive Stace gives a rarity rating of [R]. Clive Stace does not give the latter one a separate common name; they are all Grey Sedges to Stace. Other pending research suggests that there are more than just two sub-species: 7 sub-species!
Grey Sedge Carex divulsa ssp. divulsa has greyish-green to dark-green leaves (yellowish green for Leer's Sedge ) a much longer inflorescence of 5 to 18cm (4 to 8cm for Leer's Sedge ); the spikes lower down the stem being well spaced out (presumably they are closer together for Leer's Sedge ); utricles (the bottle-like flask) 3.5 to 4.25mm (being slightly smaller than the 4 to 4.8mm of Leer's Sedge ); utricles (the bottle-like flask) usually greenish-brown (reddish brown when ripe for Leer's Sedge ).
The photos above are from five different locations on differing dates and may well be of differing sub-species. Your Author will let the reader try to decide which sub-species each photo represents, but don't forget that it is thought that there are 7 sub-species, not just the two detailed here... Good luck, you may need it.
So with this indecision and lack of facts about most of the specimens' parameters in mind, your Author has left all the captions blank and leaves it to the reader to fill them in as best he can...
Easily mis-identified as : any of the proposed but unspecified 7 sub-species of Carex divulsa [particularly when only 2 of the sub-species are detailed above!]
