Derivation of the botanical name:
Humulus, Low German word humela for 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.
The female fruit of the common hop is used to flavor beer and prevent bacterial contamination during fermenting.
