Family Cannabaceae
Humulus lupulus L.
common hop, hop
Humulus: Latin name of uncertain origin, may have descended from Low German word humela, hop; which is the common name of this genus placed by Munz in the Moraceae or mulberry family, but moved by Jepson along with Cannabis into the new family Cannabaceae.
lupulus: literally a "small wolf," alluding to the plant's habit of climbing over and smothering trees on which it grows. H. lupulus is the European hop and was once called "willow-wolf" because of its propensity for climbing on willows
