The Voynich Botanical PlantsFolio 87v
Folio 87v, Lousewort or Wood Betony (Pedicularis flammea), is found throughout the Northern Hemisphere. Its extensive root system is semi-parasitic on the roots of other plants. The leaves are alternate and bipinnate; the bilaterally symmetrical flowers grow in racemes. The name lousewort comes from the belief that when cattle ate this plant they became infested with lice.
