ABSTRACT
The taxonomic status of Humulus L. in North America has been debated for over 150 years. Recent molecular and morphological studies have positively identified three distinct evolutionary lineages among wild varieties of Nearctic Humulus. Here we review these studies, and present morphological evidence supporting the recognition of three North American species of Humulus. Humulus neomexicanus (A. Nelson & Cockerell) Rydb. and Humulus lupuloides (E. Small) Tembrock, comb. & stat. nov., and Humulus pubescens (E. Small) Tembrock, comb. & stat. nov. are elevated from their former positions as varieties of Humulus lupulus.
