On the systematic position of the genus Nyctanthes L. (Oleaceae / Verbenaceae / Nyctanthaceae)

Abstract

Based on the carpological data we have clarified the position of the genus Nyctanthes within the Magnoliophyta system. We have discovered the diagnostic characteristics of the fruit structure of the Nyctanthes genus that prevent its inclusion into either Oleaceae Hoffmanns. et Link. or Verbenaceae Adans. family. We have confirmed the correctness of segregation of the Nyctanthes genus into the separate Nyctanthaceae J. Agardh. family. We provide a conspectus of the Nyctanthaceae family that includes a single genus Nyctanthes with two species N. arbor-tristis L. and N. aculeata Craib. For N. arbor-tristis we have selected a lectotype.
