Vines that climb with hooked hairs; Latin Humulus may mean “hop”
Species
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, and the word shows up again in the species Medicago lupulina
