摘要：
Several floral microcharacters (configuration of stigmatic areas on the inner surface of the style branch, shape of the anther apical appendage, anther size, and configuration of the endothecial thickenings and of the filament collar) in 63 populations representing 35 species and one variety of Sinosenecio (Senecioneae-Asteraceae) were investigated. The floral micromorphological data obtained are highly consistent with evidence from molecular systematics and cytology, strongly suggesting a polyphyletic nature of the currently circumscribed Sinosenecio and the necessity of a taxonomic change at generic level.
