Gymnadenia conopsea
"Over quite extensive areas dwarf sedge "Carex humilis" becomes dominant, a species largely restricted to the downs of south west Wiltshire and Dorset. Two other species with a localised national distribution are early gentian "Gentianella anglica" and musk orchid "Herminium monorchis". The latter is found in an area particularly rich in orchids including pyramidal "Anacamptis pyramidalis", bee "Ophrys apifera", common spotted "Dactylorhiza fuchsii", fragrant "Gymnadenia conopsea" and twayblade "Listera ovata"."
