last International Botanical Congress," Planchon's generic designation 

 should be the one to be retained. Gagnepain ' has clearly shown that 

 Landukia Planch, is not generically distinct from Parthenocissus. Landukia 

 Planch, has page priority over Parthenocisstis Planch., and hence has claims 

 to recognition as the valid generic name, for the group under discussion, 

 among those botanists who accept the generic lists of nomina conservanda 

 adopted by the last two International Botanical Congresses. That Landukia 

 should be included in the next list of nomina rejicenda is evident, and I 

 prefer to make no new combinations under this generic name at the present 

 time. The proper specific name for a common Chinese species, however, 

 needs adjustment, as there is no reason whatever for discarding Plume's 

 very descriptive name for the plant now known as Parthenocissus landuk 

 Gagnep. Ampelopsis heterophylla Sieb. & Zucc. was published many years 

 after Blume's binomial, and of course does not invalidate Blume's specific 

 name.
