Andromeda polifolia L. (Bog Rosemary), peat bog Paluaccio di Oga, Valtellina.
I have found this page of Iter lapponicum (Lapland journey) where Linnaeus writes (in Swedish and Latin) about this plant.
"Chamaedaphne Buxb. or Erica palustris pendula, fl. petioliolo purp. was now standing in its highest beauty, decorating the swamp most agreeably. ... As I looked at her, I remembered Andromeda as depicted by poets. ... She was chained in the middle of water. She always stands fixed on some tussock in the wet swamp, as on a rock in the sea. She stands in water up to her knees, up above the root, namely. She is always surrounded by poisonous dragons and animals, i.e. by mean toads and frogs, which here during spring time squirt water upon her while mating. She stands and bows her head down with sorrow. Her capitula florum [little flower heads] bend down with rosy cheeks, the cheeks turn pale more and more, capitula pallescunt magis magisque, hinc Andromeda dixi, folliis acutis [the cheeks turn pale more and more, therefore I called her Andromeda with pointed leaves]. She almost lies down, the neck is bare, hinc carneus [therefore fleshy]"
