Original diagnosis/description

Spadix cylindrical; flowers numerous, helically arranged, bisexual, perigonate. Tepals six, in two whorls, free, triangular, hooded. Gynoecium flask-shaped, stylar region long, conical, exserted beyond tepals. Ovary trilocular; ovules one per locule. Placentation axile; seeds hemianatropous, verrucose.


The name Bognerospadix (Bogner + spadix) is proposed to honor the late Josef Bogner, international authority on the monocot family Araceae, tenacious promoter of aroid research, good friend, and supporter of all who engage in the study of Araceae.
