摘　　要：熊猫马先蒿(Pedicularis pandania)是在四川卧龙国家级自然保护区发现的马先蒿属一新种。该新种属于互生叶类群,其基生叶成丛,花冠属于短管有喙型,且下唇将喙包裹住,花管在近萼端发生约180度的扭旋使得花冠下唇在侧上方,这一特征明显区别于其他国产马先蒿物种。分子系统发育分析结果表明,熊猫马先蒿是Clade 7成员,虽然与火焰系、假欧氏系、喙齿系、拟蕨系和长喙系等成员构成姐妹关系,但熊猫马先蒿的花冠形态特征明显区别于近缘物种。Pedicularis pandania(Orobanchaceae)was a new species discovered in the Wolong National Nature Reserve,Sichuan,China.This new species belongs to the alternative-leaved group that characterizing by having abundant basal leaves or only 1-3 cauline leaves,short-tubed and beaked corolla,and the lower lip completely enveloping the beaked galea.Due to the corolla tube was strongly twisted near the calyx,the corolla lower lip was completely upside down,which was distinguished from other Chinese species.Phylogenetic analyses showed that P.pandania fell into the Clade 7,as a sister to species in Ser.Flammeae,Ser.Pseudo-oederianae,Ser.Rhynchodontae,Ser.Filiculae and Ser.Macrorhynchae.Morphologically,however,the new species is easily discriminated from them in the corolla form as mentioned above.
