Robert W. Freckmann Herbarium


Because of technology changes and personnel changes at UWSP and the Wisconsin State Herbarium, the database of plant species housed at this site was merged with the database from the OLD WisFlora website to create a new Flora of Wisconsin website at Currently we are encouraging all Wisplant viewers to begin using the Flora of Wisconsin website as soon as possible. Wisplants will remain operational through July 13th. After that date, all traffic to Wisplants will be redirected to the Flora of Wisconsin website.

Hieracium piloselloides Vill.
glaucous king-devil, tall hawkweed
Hieracium: classical name hierakion from ancient Greek hierax, "a hawk". The Roman naturalist Pliny believed that hawks fed on this plant to strengthen their eyesight and thus it became the Greek and Latin name for this and similar plants, called hawkweed.
piloselloides: pilosus for "hairy;" oides for "like;" hence "hairy-like"
