Dactylorhiza traunsteinerioides (Pugsley) Landwehr Narrow-leaved Marsh-orchid National Status: Endemic, Nationally Scarce, not threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Woodwalton Fen SSSI & SAC TL227838 2006 (MM) Endemic to Britain and Ireland. First recorded for Huntingdonshire in 1978 and only a few plants occur in any one year (none in some years). Only one plant was seen in 2006 (see photo). Danthonia decumbens (L.) DC. Heath-grass National Status: Not scarce, not threatened County Status: Rare (3 sites, 4 tetrads) Site Grid Reference Last Record Godmanchester Eastside Common TL27067153 2010 (NM) RAF Molesworth County Wildlife Site TL067773 (centroid) 2003 (NM & MB) Woodwalton Fen SSSI & SAC Compartment 41 Compartment 76 29 TL227851 TL227838 2010 (MM) 2010 (MM) In Huntingdonshire this is a rare grass of clay pastures, fens and alluvial pastures with surface acidification. Our grasslands have probably not been examined in as great a detail over recent years as they have been historically. Old sites include Hemingford Grey and Upwood Meadows. Deschampsia flexuosa (L.)

Not re-found until 2007 when MM found one small tuft in flower. Dianthus armeria L. Deptford Pink National Status: Endangered County Status: Extinct in the wild This species, last seen in 1984, is currently extinct as a truly wild plant, however seed from Woodwalton Fen is maintained in cultivation locally and attempts are being made to establish this species in two recently established, favourably managed, wildflower meadows at Ramsey Heights. Early signs indicate a modicum of success but it will be several years before it can
