The Voynich Botanical Plants

Folio 43v, Couch grass (Elytrigia repens), is a grass common to most of Europe and Asia. It is an invasive grass due to a creeping rhizome root. The leaves are long and linear and the long flower spike has spikelets with three to eight florets. The Greeks used couch grass as a herbal remedy. In medieval times it was used to treat bladder and urinary tract infections. Sick dogs will dig up and eat the roots.
