Distribution and ecology. – Benstonea adinobotrys occurs from (400-) 1400-2250 m in humid forest ( JEBB, 1992). It is known in Indonesia (Sulawesi, West Papua) and Papua New Guinea.

Observations. – This taxon comprises a complex that includes several “morpho-species” that have been described based on slight variations in leaf length and width, and the dimensions and number of syncarps. As stated by STONE (1983c), the “limits of variation within members of this group are still not very well understood, and further field study of them is desirable”. The taxonomic revision of Pandanaceae for the region currently being undertaken by Ary Keim and collaborators will hopefully clarify this matter. Some of the names placed in synonymy above may represent entities that justify recognition at the species level, in which case new combinations in Benstonea will be required.
