The disposition of the name Humulus scandens (Loureiro) Merrill, based
on Antidesma scandens Loureiro, is problematic. E. D. Merrill (1935) was
convinced that the name A . scandens applied to the species Humulus
japonicus . If Merrill was correct, then the combination Humulus
scandens would have priority. The material described by Loureiro,
however, was not preserved, and his description does not coincide with
that of H . japonicus. Il y a eu cependant une demande de rejet de H. scandens / H. japonicus en 2009, demande de rejet qui a été rejetée en 2011, qui va elle dans le sens d'une syn. entre les deux taxons.
