The flowers actually do have the same triplet of lower petals as does Lousewort, but in the case of Marsh Lousewortthe 3 petals overlap each other and it is not as easy to see that they are in triplets. The corolla is between 2 to 2.5cm long. The calyx has lobes which are variously dissected (whereas there are 4 lobes on Lousewort) |

Deeply cut leaves are to be found all the way up the stem, but getting sparser nearer the top apart from a bunch of smaller still-growing leaves at the summit. |

The lobes of the petals are more distinct here. |

The flowers have a semi-upright main 'petal' - in a tubular shape with a hood containing the sexual organs. the other 3 lower flat petals may have dropped off most of if not all of these specimens. The upper lip has just one tooth at the end. The calyx tube from which the flower on the right emerges has a few hairs. |

The leaves, much nearer ground level. The flowers above them have just their tubular cups left and a brown and spent sexual organ protruding from it. |
Many similarities to : Lousewort (Pedicularis sylvatica) which resides in the same Genus. Differences mentioned in captions.
