Recent phylogenetic investigations about Jasminum s.l. have shown that species possessing both alternate leaves and yellow flowers (sect. Alternifolia ) constitute a clade (monophylum) that is sister to all the other sections of the genus or even to Jasminum itself plus the American/South African genus Menodora . Such evidence sets the need to revise the generic delimitation of Jasminum by establishing a separate genus for the species belonging to sect. Alternifolia . As a consequence, the new genus Chrysojasminum is here established and the relevant nomenclatural combinations are supplied for fifteen taxa.
