thrum plants are presumably not <strong>the</strong> only ones found in cultivation. Given this, it would seem<br />
sensible to treat all populations as native unless <strong>the</strong>y are obviously associated with a garden<br />
setting or unless <strong>the</strong>ir origin can o<strong>the</strong>rwise be elucidated. All but three <strong>of</strong> <strong>the</strong> sites listed above<br />
fall within <strong>the</strong> floodplain <strong>of</strong> <strong>the</strong> River Great Ouse. The remaining three known sites are fenland<br />
drains.<br />

This species is rare in <strong>Huntingdonshire</strong> and neighbouring counties. The recent finds in<br />
<strong>Huntingdonshire</strong> mirror similar recent finds elsewhere, for example in Northamptonshire and<br />
Cambridgeshire. Is this species recovering lost ground or extending its range?<br />

This is a species <strong>of</strong> fen dykes, river banks, ponds and occasionally wet meadows. It is only<br />
locally distributed within <strong>Huntingdonshire</strong> and is becoming scarce (Wells, 2003). There is an<br />
additional record from a meadow at Ramsey Heights where it has been sown and where it is<br />
unlikely to persist.<br />
