The most common Sundew. Probably more than one plant intertwined here. |

Two flowering stems thrust skywards from near the centre. |

Two flowering stems arise 6 inches from near the middle of the basal rosette. |

A basal rosette of round leaves rather than oblong as in Oblong-Leaved Sundew. Flowering stalks appear from the near the centre of the rosette (buds arising in photo) |

Un-like either Oblong-Leaved Sundew or Great Sundew the leaves abut abruptly onto the stalks and do not taper into them. |

The clear sticky mucilage on the tips of the hairs have ensnared an insect, the mucilage having rubbed off the hairs it has touched. |

Just the upper surface and edge of the leaf are covered in sticky hairs, forming a pin-cushion. The leaves are lime green, but redden in strong sun. |

A flowering stalk slowly un-curls from the centre, the top-most section still to un-furl. Flower buds have not yet opened. |

A curled-up flowering stalk spirals around (with un-opened flower buds). Another next to it is bent into a U-shape, yet to fully erect. |

This flowering stem has more flowers than do most, although not open in the rain. |

When flowering the flower stalk erects itself bolt upright straightening out the umbrella-handle curve in the upper stem. |

At last, a specimen with an opened flower :-)
5 white petals with 5 splayed-out but short filaments with anthers. The flower buds just below the top have yet to open, whilst those below them look like they might be turning to fruit. |
Easily mis-identified as : Oblong-Leaved Sundew (Drosera intermedia) but that has oblong rather than round leaves. Hybridizes with :
Uniquely identifiable characteristics Distinguishing Feature : The round leaves should distinguish it from two other sundews, although it does hybridize with them.
No relation to : Grows in upland acid peat bogs and other wet upland places. It is carnivorous eating insects. See Great Sundew for how it accomplishes this. Round-leaved Sundew has been used in folk medicines for a long time to treat colds, coughs, bronchitis and asthma. In Italy it is used in a liqueur. Sundews are carnivorous plants which trap insects in their leaves, dissolve them and absorb the resulting nutrient soup for use by the plant itself. The leaves exhibit Thigmonasty, moving in response to touch. See Great Sundew for modus operandi.
