| Leafy lousewort may be found in open coniferous woods or in openings in the forest at timberline. |
| Swamp lousewort, however, is a taller, more upright plant, and its leaves have no stalk or only a very short stalk. |
| Sneezewort, milkwort and lousewort were not noticed in 1999 but sneezewort had returned in 2000, perhaps due to cattle grazing and winter management, i.e bramble clearance. |
| A shockingly pink woolly lousewort that makes our naturalist guide squeal with delight. |
| The lousewort grows mostly on north-facing riverbanks because the vegetation is less dense there. |
| The stem of the lousewort is hairy, and the leaves grow very close to it. |
