Phylogeny and systematics of the genus Osmanthus (Oleaceae) based on molecular (plastid and nuclear) and morphological evidence.

The genus Osmanthus belongs to Oleaceae Subtribe Oleinae comprising about 35 species, which are previously divided into five Sections, Leiolea, Osmanthus, Linocieroides, Siphosmanthus and Notosmanthus. Previous studies were either based on plastid data only or based on both plastid and nuclear data but the sampling was small. In addition, although it’s suggested as polyphyletic, an circumscription of Osmanthus based on morphological and molecular evidence has not been available yet. In the present study, based on molecular data of four plastid markers and one nuclear marker, we reconstruct a global phylogeny of Osmanthus. The 2 major clades identified earlier are recovered here and we further identified a new major clade. The inclusion of Osmanthus Sect. Notosmanthus in the genus Notelaea is confirmed for the first time. Based on the newly reconstructed phylogeny and evidence from morphology, the four species of Osmanthus Sect. Leiolea is suggested to establish a new genus.
