Luzula multiflora (Ehrh.) Lejeune ssp. multiflora Heath Wood-rush National Status: Not scarce, not threatened County Status: Scarce (3 sites, 5 tetrads) Brampton Wood SSSI Holme Fen SSSI: Compartment 3 Middle Covert Holme Lode Covert Site Grid Reference Last Record TL179699 TL18327042 TL1989 TL2188 TL2089 2008 (DB) 2008 (DB) 2006 (MM) 2008 (DB) 2007 (DB) Monks Wood SSSI TL19918006 2009 (DB) Uncommon and apparently restricted to protected ancient boulder clay woodlands and fens. Scarcer than ssp. congesta, but it may be slightly under-recorded (the species aggregate is comparably scarce) as the subspecies were not distinguished by Wells (2003). Luzula pallidula Kirsch. Fen Wood-rush National Status: Nationally Rare, Critically Endangered, BAP County Status: (2 sites, 4 tetrads) Holme Fen SSSI: Compartment 15a Compartment 41 Woodwalton Fen SSSI & SAC: Compartment 54 Compartment 82 Site Grid Reference Last Record TL198885 TL213889 TL22648454 TL226835 2006 (MM) 2008 (MM) 2009 (MM) 2005 (MM) The first record of this species for Britain was made from Woodwalton Fen in 1907. It is a diminutive, short-lived species that requires regular disturbance. It forms a persistent seed bank and can appear in great quantity when the fen peat is disturbed, for example when carr is cleared (Wells, 2003). Lythrum portula (L.) D.A. Webb Water-purslane National Status: Not scarce, not threatened County Status: Rare (3 sites, 4 tetrads) Site Grid Reference Last Record Brampton Wood SSSI TL182699 2009 (DB) TL1870 2002 (TW & HFFS) Grafham, West Wood TL153701 1997 (TW) Monks Wood SSSI TL199803 2008 (DB) 46
TL198805 TL196803 2009 (DB) 2009 (DB) The populations present in Brampton Wood and Monks Wood have been determined as ssp. portula. The remaining population has not yet been determined but is likely to be this subspecies also. Melampyrum cristatum L. Crested Cow-wheat National Status: Nationally Rare, Vulnerable, BAP County Status: Rare (2 sites, 2 tetrads) Site Grid Reference Last Record Monks Wood SSSI TL194793 2009 (DB) Stonely, Stocking Lane TL123695 2008 (BD) This summer annual species is an obligate hemiparasite of various woody and herbaceous species, predominantly found on the margins of ancient oak woods and in their clearings and rides. It occasionally grows on roadside verges and hedgebanks where these at one time bordered woodland. It is thermophilous and largely restricted to the areas of Britain with the most continental climatic regime, where it grows on calcium-rich soils derived from boulder clay (Stewart et al. 1994). Molinia caerulea (L.) Moench ssp. arundinacea (Schrank) K. Richt. Purple Moor-grass National Status: Waiting List County Status: Rare (2 sites, 4 tetrads) Holme Fen SSSI Site Grid Reference Last Record TL209889 TL197896 TL200901 2009 (SL) 2009 (SL) 2008 (DB) Woodwalton Fen SSSI & SAC TL229836 2008 (DB) This is a rare but locally abundant species of our more acid fen peats. At Holme Fen, it is has declined in abundance as a result of the closing over of the birch canopy (Wells, 2003). Mycelis muralis (L.) Dumort. Wall Lettuce National Status: Not scarce, not threatened County Status: Rare (3 sites, 3 tetrads) Site Grid Reference Last Record Holme Fen SSSI, Holme Lode Covert TL20658916 2009 (DB) Huntingdon, All Saint’s Church TL239718 2006 (KW) Paxton Pits TL1862 2006 (AD) 47
