灯心草科

In this study, 6 species from Eriocaulaceae, Xyridaceae, Commelinaceae, Juncaceae were collected as material.

本试验以谷精草科，鸭跖草科，黄眼草科和灯心草科为研究对象。

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.

从构建的系统发育树可以得到：①谷精草科独立形成一个植物类群，支持谷精草科独立成为谷精草目；②谷精草科与鸭跖草科聚成一个大的类群，说明两科的亲缘关系较近，并且表现为平行进化；③灯心草科不近缘于谷精草科，与禾本科相比，灯芯草科与莎草科之间存在更近的亲缘关系；④在进化程度上，灯心草科比谷精草科原始；禾本科与谷精草科的亲缘关系最远，并且在这几个科中处于最原始的进化地位；⑤系统树还支持谷精草科内部的系统关系，支持谷精草属在谷精草科中的原始系统位置。
