The genus <em>Osmanthus</em> Lour. was published by Loureiro (1790) with the typus was <em>O. fragrans</em> Lour. In Vietnam, based on Loureiro (1790), F. Gagnepain (1933), P. H. Ho (2003), T. D. Ly (2003) and B. H. Quang (2014) there are 2 species in sections <em>Leiolea</em>, <em>Osmanthus</em>. During studying specimens of this section in the Herbaria, we introduced <em>O. suavis</em>. in section <em>Siphosmanthus,</em> as a new record for flora of Vietnam. This species has distribution in Lao Cai, Thanh Hoa. Species<em> </em><em>O.suavis</em>. was closed to <em>O</em><em>.</em><em> </em><em>delavayi </em>by Cymes fascicled in leaf axils or terminal, but<em> O. suavis</em><em> </em>different with <em>O</em><em>.</em><em> </em><em>delavayi, </em>by (leaves petiole 5-7 (10) mm, primary viens 5-8 on each side of midrib and Drupe blue-black, ellipsoid or ovoid, ca. 8 x 5 mm.). vs (leaves petiole 2-3 mm, primary viens 4-5 on each side of midrib, Drupe blue-black, ellipsoid or ovoid, ca. 1-1.5 cm). In this article, we introduce nomenclature, key to species, morphology and illustration, distribution and research specimen of all species in genus <em>Osmanthus</em> Lour. in Vietnam.</p><p> </p> ER -
