摘要: 牛膝菊(Galinsoga parviflora Cav.)和粗毛牛膝菊(Galinsoga quadriradiata Ruiz. et Pav.)为辽宁省两种重要入侵植物,目前国内文献对这两种植物的形态描述有混淆。根据沈阳农业大学植物标本室收藏的标本并比对采集于沈阳市附近的标本,作者明确这两种牛膝菊属植物的主要区别在于冠毛:前者的舌状花无冠毛或冠毛为细短毛,管状花的冠毛羽筛状,先端钝;后者的舌状花和管状花的冠毛均呈羽筛状,先端尖。该性状差异可为准确鉴别该属杂草提供形态学依据。

关键词: 牛膝菊属, 牛膝菊, 粗毛牛膝菊

Abstract: The diagnoses between Galinsoga parviflora Cav. and Galinsoga quadriradiata Ruiz. et Pav., two invasive plants in Liaoning Province, are still in confusion in morphological traits in some Chinese studies. On the basis of the two plants specimens of Shenyang Agricultural University herbarium and the comparison of these specimens with the new collected ones in Shenyang area, the key morphological distinction between the two Galinsoga species is the G. parviflora's ray florets have no pappus or the ray floret's pappus are speculations, and the tubular flower's pappus are plumose-cribriform with obtuse apex, while G. quadriradiata's pappus of both ray floret and tubular flower are plumose-cribriform with acute apex. These results showed definite morphological characters in identifying Galinsoga weeds.

Key words: Galinsoga, Galinsoga parviflora Cav., Galinsoga quadriradiata Ruiz. et Pav.
