    摘要:

    报道了木兰科(Magnoliaceae)含笑属(Michelia L.)一新种:台山含笑(M. taishanensis Y. H. Tong,X. E. Ye,X. H. Ye & Yu Q. Chen)。该新种目前仅分布于我国广东台山市的北峰山,与广东含笑(M. guangdongensis Y. H. Yan,Q. W. Zeng & F. W. Xing)近缘,但其叶柄更纤细,叶背老时变无毛,雄蕊较多且较长,花丝白色,药隔短小而与后者区别。

    Abstract:

    A new species of Magnoliaceae, Michelia taishanensis Y. H. Tong, X. E. Ye, X. H. Ye & Yu Q. Chen is reported, which is currently known only from Beifeng Mountain in Taishan City, Guangdong, China. This species is similar to M. guangdongensis Y. H. Yan, Q. W. Zeng & F. W. Xing, but differs from the latter by its more slender petioles, leaf blades with glabrescent abaxial surface, and more and longer stamens with white filaments and much shorter anther connectives.
