土茯苓屬(菝葜科)之學名修訂 Nomenclatural Alterations in Genus Heterosmilax (Smilacaceae)

基於兩屬間甚小的形態差異及近年分子譜系學之研究結果，土茯苓屬 Heterosmilax (菝葜科Smilacaceae)應處理為菝葜屬 Smila 之異名。本文因此將土茯苓屬已知之12種轉移至菝葜屬，並提出必要之新分類處理，共計2新名(S. duclouxii 與 S. vietnamensis) 及7新組合名 (S. chinensis, S. longiflora, S. polyandra, S. seisuiensis, S. septemnervia 與 S. sumatrensis)。

Based on the negligible morphological differences between the two genera and recent molecular phylogenetic studies, the genus Heterosmilax (family Smilacaceae) should be treated as a synonym of the genus Smilax. Accordingly, this paper transfers all 12 known species of Heterosmilax to Smilax, and puts forward necessary taxonomic treatments, including two new names (S. duclouxii and S. vietnamensis) and seven new combinations: S. chinensis, S. longiflora, S. polyandra, S. seisuiensis, S. septemnervia and S. sumatrensis.
