vegetation. It is capable <strong>of</strong> forming a large and persistent seed bank and when peat was still<br />
dug commercially in <strong>the</strong> Fens, a show <strong>of</strong> Viola persicifolia <strong>of</strong>ten appeared in <strong>the</strong> wake <strong>of</strong> <strong>the</strong><br />
peat diggers. During <strong>the</strong> 1960’s and 1970’s it appeared in abundance in various parts <strong>of</strong><br />
Woodwalton Fen in <strong>the</strong> years following <strong>the</strong> extraction <strong>of</strong> fen carr and disturbance caused by<br />
excavating clay for waterpro<strong>of</strong>ing <strong>the</strong> banks around <strong>the</strong> SSSI. It is currently very rare at<br />
Woodwalton Fen but its decline might be reversible with appropriate management (Palmer,<br />
2006a).<br />

This species has always been rare in <strong>Huntingdonshire</strong> where it has been confused with some<br />
<strong>of</strong> <strong>the</strong> variants <strong>of</strong> Viola arvensis (Wells, 2003) and possibly with plants <strong>of</strong> hybrid origin also<br />
(hybrid swarms are abundant in parts <strong>of</strong> <strong>the</strong> Soke <strong>of</strong> Peterborough). Any future records<br />
should be supported by specimens or o<strong>the</strong>r appropriate evidence.<br />

This hybrid might arise as a result <strong>of</strong> crosses involving ei<strong>the</strong>r Viola canina subspecies. It is<br />
<strong>of</strong>ten very vigorous, but so infertile that <strong>the</strong> possibility <strong>of</strong> back-crossing is very unlikely. This<br />
hybrid is closer to Viola persicifolia in habit, but its flowers resemble those <strong>of</strong> Viola canina<br />
(Stace, 2010).<br />
