Under our rules of priority, if these varieties are to be recognized, the 
earliest valid names must be adopted, not those arbitrarily selected by 
Planchon. Many American botanists would consider the specific name 
heterophylla S. & Z. (1846), to be invalidated in Ampelopsis by the earlier 
Ampelopsis heterophylla Blume (1825) =PARTH ENOCISSUS HETERO-

Landukia landuk Planch., Partheno cissus landuk Gagnep.).

Gagnepain, 1. c., refers to this species Lolier 377, 878, from Luzon, which 
I have not seen. The Mindanao specimens agree closely with the descrip- 
tions of the species, and with specimens in the herbarium of the Bureau 
of Science determined by Gagnepain, Thorel 1392 from Cochinchina, and 
Bons d’Anty from Yunnan.
