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.
