摘要:

该文报道了在泰国北部和中国西南部的菊科一个新归化属——苹果蓟属(Centratherum Cass.)。依据所采集的标本,详细描述了该属在东南亚大陆的唯一代表亚种苹果蓟 [Centratherum punctatum Cass. Subsp. fruticosum(S. Vidal)K. Kirkman ex Shih H. Chen, M. J. Wu & S. M. Li],并配以插图。苹果蓟与其所在属的其他种的区别在于该亚种叶片菱形至椭圆形,叶缘具不规则锯齿,先端微尖,总苞片基部硬化,先端无芒。文中还提供了苹果蓟的分布图,并讨论了其可能的传播途径。

Abstract:

Centratherum Cass., a newly naturalized genus of the family Asteraceae from Southeast Asia, was recorded in North Thailand and Southwest China. C. punctatum Cass. Subsp. fruticosum(S. Vidal)K. Kirkman ex Shih H. Chen, M. J. Wu & S. M. Li, the only one representative subspecies of this genus from mainland of Southeast Asia, is described and illustrated based on the specimens. C. punctatum Subsp. fruticosum can be distinguished from the other taxa of this genus by its leaf blade rhombic to elliptic, leaf margins irregularly serrate, leaf apex broadly acute, and phyllaries indurate at base and not awned. Its distribution map is provided and the possible dispersal pathway is discussed.
