Dryopteris borreri (Newman) Newman ex Oberh. & Travel Borrer’s Male-fern National Status: Not scarce, not threatened County Status: Scarce (4 sites, 4 tetrads) Site Grid Reference Last Record Gamlingay Wood, Hazelcroft TL241536 2008 (SH) Holme Fen SSSI TL2088 2006 (MM) Woodwalton Fen SSSI & SAC, Compartment 66 TL227840 2002 (MM) Waresley Wood SSSI TL263545 2009 (DB) A rare species in Huntingdonshire, occurring as singletons or only in very low numbers, that can be found in damp fenland and ancient woodlands. All our plants have been identified as, or are believed to be, the above species, but it is possible that Dryopteris affinis sens. str. may also occur. Dryopteris carthusiana (Vill.) H.P. Fuchs Narrow Buckler-fern National Status: Not scarce, not threatened County Status: Scarce (2 sites, 4 tetrads) Site Grid Reference Last Record Holme Fen SSSI TL1989 TL20328999 TL2090 2006 (MM) 2008 (DB) 2008 (DB) Woodwalton Fen SSSI & SAC TL22988382 2008 (DB) A rare, but locally abundant, species of damp fen and boulder clay. It may be under-recorded but probably not to the extent that it would no longer qualify for inclusion in the Rare Plant Register. Eleocharis uniglumis (Link) Schult. Slender Spike-rush National Status: Not scarce, not threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Woodwalton Fen SSSI & SAC TL232841 2005 (MM) This species is scattered throughout Britain but is being lost from many inland sites. At inland lowland sites it typically occurs in association with Juncus subnodulosus fen-meadows (Jermy et al. 2007). 26
Epilobium palustre L. Marsh Willowherb National Status: Not scarce, not threatened County Status: Rare (3 sites, 3 tetrads) Site Grid Reference Last Record Holme Fen SSSI: Compartment 8 Compartment 21 TL2089 TL2088 (monad) 2006 (MM) 2006 (MM) Monks Wood SSSI TL19907999 2009 (DB) Paxton Pits Nature Reserve TL195630 2005 (RE) A rare species of damp woodland glades and the margins of ditches and ponds. Epipactis helleborine (L.) Crantz Broad-leaved Helleborine National Status: Not scarce, not threatened County Status: Rare (2 sites, 2 tetrads) Site Grid Reference Last Record Stibbington Pits Nature Reserve TL088993 2003 (TW) Weaveley Wood TL228539 1995 (TW) A species of old deciduous woods that, while always scarce, used to be more widespread in the past. It has probably declined as a result of changes to woodland management and probably also increased numbers of deer, particularly the smaller non-native species. Epipactis purpurata Sm. Violet Helleborine National Status: Not scarce, not threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Monks Wood SSSI TL19_79_ 2009 (DB) This is a late-summer flowering species of lowland deciduous woodland on chalk and clay soils. It is very shade tolerant (Lang, 2004) and at Monks Wood occurs beneath a dense canopy of hazel, ash and oak. A large proportion of the Monks Wood colony is kept caged during the growing season to protect against grazing by rabbits and deer. Erica tetralix L. Cross-leaved Heath National Status: Not scarce, not threatened County Status: Rare (2 sites, 3 tetrads) Holme Fen SSSI Site Grid Reference Last Record TL198894 2009 (SL) TL200894 2008 (DB) 27
