Abstract

A molecular systematic study of Scrophulariaceae sensu lato using DNA sequences of three plastid genes (rbcL, ndhF, and rps2) revealed at least five distinct monophyletic groups. Thirty-nine genera representing 24 tribes of the Scrophulariaceae s.l. (sensu lato) were analyzed along with representatives of 15 other families of Lamiales. The Scrophulariaceae s.s. (sensu stricto) include part or all of tribes Aptosimeae, Hemimerideae, Leucophylleae, Manuleae, Selagineae, and Verbasceae (= Scrophularieae) and the conventional families Buddlejaceae and Myoporaceae. Veronicaceae includes all or part of tribes Angelonieae, Antirrhineae, Cheloneae, Digitaleae, and Gratioleae and the conventional families Callitrichaceae, Globulariaceae, Hippuridaceae, and Plantaginaceae. The Orobanchaceae include tribes Buchnereae, Rhinantheae, and the conventional Orobanchaceae. All sampled members of Orobanchaceae are parasitic, except Lindenbergia, which is sister to the rest of the family. Family Calceolariaceae Olmstead is newly erected herein to recognize the phylogenetic distinctiveness of tribe Calceolarieae. The Calceolariaceae are close to the base of the Lamiales. The Stilbaceae are expanded by the inclusion of Halleria. Mimulus does not belong in any of these five groups.

摘要

采用三个质体基因（rbcL、ndhF 和 rps2）的 DNA 序列对广义玄参科进行分子系统学研究，揭示了至少五个明显的单系群。分析了代表广义玄参科（广义）24 个族的 39 个属，以及唇形目 15 个其他科的代表。狭义玄参科（狭义）包括 Aptosimeae、Hemimerideae、Leucophylleae、Manuleae、Selagineae 和 Verbasceae（= Scrophularieae）以及传统科 Buddlejaceae 和 Myoporaceae 的部分或全部。Veronicaceae 包括 Angelonieae、Antirrhineae、Cheloneae、Digitaleae 和 Gratioleae 以及传统科 Callitrichaceae、Globulariaceae、Hippuridaceae 和 Plantaginaceae 的部分或全部。列当科包括 Buchnereae、Rhinantheae 和传统的列当科。除 Lindenbergia 外，列当科的所有采样成员都是寄生的，而 Lindenbergia 则与该科的其他成员形成姐妹关系。Calceolariaceae Olmstead 家族是新成立的，以识别 Calceolarieae 族的系统发育独特性。Calceolariaceae 与唇形目基部关系密切。 Stilbaceae 通过包括 Halleria 而得到扩展。Mimulus 不属于这五个组中的任何一个。
