Herbarium: Medicinal Plants as Information

Polygonum lapathifolium, a stem of which is shown here, has been known for some time.

In fact, it has been documented in illustrations within materia medica. William Dickes and Anne Pratt, for instance, produced a chromolithograph of P. lapathifolium in 1855, detailing the flowers and leaves of the plant.
