Monks Wood SSSI Upton Wood TL190795 TL19438007 TL201808 TL17997986 TL18007989 2008 (DB) 2009 (DB) 2009 (DB) 2009 (DB & LF) 2009 (DB & LF) This easily overlooked tree is widely but sparsely distributed in, and indicative of, ancient woodlands on the boulder clay. In the future, distinctions between native and introduced populations are likely to become clouded as a result of plantings e.g. at Lady’s Wood, Littless Wood and Ramsey Heights Clay Pits. Stachys arvensis (L.) L. Field Woundwort National Status: Near Threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Colne, allotments TL384753 1998 (SW) Although this species remains frequent over much of its British range it has declined in some areas, probably as a result of increases in winter cropping, the use of broad-spectrum herbicides, the increased use of nitrogen-based fertilisers and the planting of more competitive crop cultivars (Wilson & King, 2003). It has always been rare in Huntingdonshire (Wells, 2003). Stellaria alsine Grimm. Bog Stitchwort National Status: Not scarce, not threatened County Status: Rare (3 sites, 5 tetrads) Site Grid Reference Last Record Agdengreen Wood TL146622 1998 (BD & JaC) Aversley Wood SSSI Woodwalton Fen SSSI & SAC TL15718157 TL16118220 TL22888383 TL23078408 2008 (DB) 2010 (DB) 2008 (DB) 2009 (DB) The classic location for this species in Huntingdonshire is Woodwalton Fen where it is widespread and locally abundant. In recent years new populations have been found on damp ancient woodland rides, a typical habitat in neighbouring counties, and there may be a few more new populations waiting to be discovered at such sites. Stellaria neglecta Weihe Greater Chickweed National Status: Not scarce, not threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Lady’s Wood Nature Reserve TL24528263 2005 (WM) 66
There is a historic record for Holme Fen, but the superficially similar Myosoton aquaticum is abundant there so future determinations need to be made with care. Stellaria pallida (Dumort.) Piré Lesser Chickweed National Status: Not scarce, not threatened County Status: Rare (2 sites, 2 tetrads) Site Grid Reference Last Record Paxton Pits TL19916255 2009 (DB) Portholme, sluice over the Alconbury Brook TL23717129 2009 (DB) This diminutive, annual species can be found in short turf or on sparsely vegetated ground, particularly in association with mineral rich soils. There is a suggestion of an affinity with populations of Cerastium semidecandrum, so it should be searched for wherever this species occurs. The population at Portholme may have been introduced with gravel. Stellaria palustris Retz. Marsh Stitchwort National Status: Vulnerable, BAP County Status: Rare (5 sites, 6 tetrads) Site Grid Reference Last Record Hemingford Meadow TL308712 2009 (BS) Holme Fen, Jackson’s Covert TL2188 2006 (MM) Needingworth, Overcote Fen TL357714 1995 (BE & JT) St Neots Common SSSI TL186615 2001 (KW) Woodwalton Fen SSSI & SAC TL23368513 TL228839 2008 (DB) 2007 (DB) In Huntingdonshire, this species has only ever been known from a very limited number of wetland sites. Woodwalton Fen is perhaps the only site where it can be found in any great abundance, and both the glaucous and green foliage variants occur here. Symphytum officinale L. ssp. bohemicum (F.W. Schmidt) Čelak. Common Comfrey National Status: Nationally Rare County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Woodwalton Fen SSSI & SAC TL23418450 2009 (DB) This rare fenland subspecies is only known in Britain from Cambridgeshire and Huntingdonshire. It is widespread through Woodwalton Fen and may occur at Holme Fen also. 67
