Info

This species has always been rare in Huntingdonshire where it has been confused with some of the variants of Viola arvensis (Wells, 2003) and possibly with plants of hybrid origin also (hybrid swarms are abundant in parts of the Soke of Peterborough). Any future records should be supported by specimens or other appropriate evidence. Viola x ritschliana W. Becker Viola canina x Viola persicifolia National Status: Nationally Rare County Status: Rare (2 sites, 3 tetrads) Site Grid Reference Last Record Holme Fen SSSI, Compartment 50 TL198893 2010 (MM) Woodwalton Fen SSSI & SAC: Compartment 84 86 TL232835 TL231850 2006 (MM) 2010 (MM) This hybrid might arise as a result of crosses involving either Viola canina subspecies. It is often very vigorous, but so infertile that the possibility of back-crossing is very unlikely. This hybrid is closer to Viola persicifolia in habit, but its flowers resemble those of Viola canina (Stace, 2010). Viscum album L. Mistletoe National Status: Not scarce, not threatened County Status: Scarce (10 sites, 10 tetrads) Site Grid Reference Last Record Alconbury, east of TL1975 2011 (MiB) Chesterton TL126942 2011 (DB) Elton, Greenhill Road TL122924 2000 (PT) Folksworth, Washingley Road TL1489 2010 (NC) Hemingford Abbots, Royal Oak Lane TL281709 2008 (LF) Hemingford Grey, Cross Keys House TL284706 2010 (LF) Hemingford Grey, Mill Lane TL295711 2010 (PeT) Hemingford Grey, St Ives Road TL306707 2010 (LF) Hemingford Grey, Victoria Terrace TL308707 2008 (PeS) Hemingford Meadow TL307712 2007 (LF) Kimbolton Castle TL101675 2008 (LF) St Ives, field behind London Road TL310706 2007 (LF) St Ives, Houghton Road TL305723 2011 (NM) Needingworth, 18 High Street TL3472 (monad) 2010 (RP) Stonely TL107672 1999 (BD) Yaxley TL1892 2007 (MH) Widely but locally distributed on a range of different trees but particularly Tilia, Malus and Populus. It seems to be particularly frequent in villages along the River Great Ouse from Hemingford Grey eastwards. Some or the colonies on trees associated with habitation may be deliberate introductions.
Vulpia unilateralis (L.) Stace Mat-grass National Status: Nationally Scarce, Waiting List County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Kimbolton Airfield TL108695 2008 (BD) This poorly known species is an early flowering spring annual. It grows in dry, open and very bare, often rubbly, places with a calcareous influence (Stewart et al. 1994). At Kimbolton Airfield it grows on thin soil that has developed over old concrete structures. 87
