Ranunculus sardous Crantz Hairy Buttercup National Status: Not threatened, not scarce County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Ellington Thorpe TL144699 2011 (BD) This is a species of damp arable field margins, tracks and disturbed grassland on heavy soils (Wilson & King, 2003). It has probably always been rare in Huntingdonshire, where it may be vulnerable to agricultural herbicides. BD found it to be abundant at the arable farmland site listed above. Rorippa x anceps (Wahlenb.) Rchb. R. amphibia x sylvestis National Status: Not threatened, not scarce County Status: Rare (1 site, 2 tetrads) Site Grid Reference Last Record Earith, River Ouse TL3774 70 TL3874 (monad) 2009 (DB) 2009 (DB) The morphology of this fertile hybrid is intermediate between that of the parents and resembles a very large R. sylvestris. It is a plant often found in the lower reaches of large rivers and can occur in the absence of both parents. It has been known at Earith since at least 1844. Rosa rubiginosa L. Sweet Briar National Status: Not scarce, not threatened County Status: Rare (3 sites, 3 tetrads) Site Grid Reference Last Record Norman Cross Pits TL16449105 2010 (NC) Paxton Pits TL196629 TL19326341 2010 (DB) 2010 (DB) Woodston Pits Nature Reserve TL17399782 2009 (DB) Very rare and at present no populations are known that can be definitively identified as native, but the above locations are plausible and should be treated as native for the time being. This species is now widely planted, e.g. by the A14 and at Crown Lakes Country Park, but these bushes seem very robust and may not be of good native stock. Rosa stylosa Desv. Short-styled Field-rose National Status: Not scarce, not threatened County Status: Rare (3 sites, 4 tetrads) Site Grid Reference Last Record Aversley Wood SSSI TL163819 2008 (DB)
Littless Wood TL128681 2008 (DB) Monks Wood SSSI TL195797 71 TL197802 2009 (DB) 2008 (DB) Upton Wood TL181795 2009 (DB) While this species is undoubtedly overlooked and poorly recorded there is sufficient evidence to suggest that it is an extremely scarce species in Huntingdonshire. It is a species of ancient woodland rides on heavy boulder clay soils. Scrub clearance works damaged the only bush I have seen in Aversley Wood and greater consideration needs to be given to the identification and adequate protection of the County’s Rose flora. Just because certain species are more challenging to identify should not mean that they are overlooked when developing site management plans and planning routine site management works. Rubus adspersus Weihe ex H. Weber a bramble National Status: Nationally Scarce? County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Woodwalton Fen SSSI & SAC TL23038380 2008 (DB) A species of heathland margins. Like R. nemoralis it is restricted to our ancient fens and has only ever been known from Woodwalton Fen. Rubus bucknallii J.W. White a bramble National Status: Endemic, Nationally Rare County Status: Rare (1 site, 2 tetrads) Site Grid Reference Last Record Dillington, road side TL126660 2000 (RR) Great Staughton, road side TL120655 2000 (RR) A rare bramble that shows an affinity for road side hedges, although this may simply be a reflection of survey bias. More surveys are needed to elucidate this species true status and distribution in Huntingdonshire. Rubus nemoralis D.J. Mueller a bramble National Status: Not scarce, not threatened County Status: Rare (1 site, 1 tetrad) Holme Fen SSSI: Holme Lode Covert Jackson’s Covert Site Grid Reference Last Record TL2088 TL217887 2006 (DB) 2009 (DB) This is a species of acid heathland and moorland habitats. It is rare in Huntingdonshire because of a lack of suitable habitat and is only known from Holme and Woodwalton Fens, and has not been recorded at the latter for many years. It is exceptionally abundant in Jackson’s Covert where it must represent an important nectar source for invertebrates.
