Glossary (beta)

ID notes: The leafy stem and lack of basal leaves of H. paniculatum readily distinguish it from our other species of Hieracium. In fact, it often puzzles the inexperienced botanist, who may overlook the possibility that this plant is a Hieracium! The milky sap and obscure teeth on the leaves are good corroborative characters.
