抽象。随着玄参科传统界限的解体，以前归入该科的大多数属的系统发育位置已经解决。然而，单型属Mimulicalyx的家族位置尚未包括在任何已发表的分子系统发育研究。在这里，我们采用了两步的方法来解决Mimulicalyx的系统发育位置使用三个数据集：（1）一个71 619 bp的质体组比对的唇形科;（2）一个数据集的6个质体DNA区域（atpB，matK，ndhF，rbcL，rps 16和trnL-trnF）的Phrymaceae;和（3）一个数据集的核核糖体内部和外部转录间隔区（nrITS，ETS）的Phrymaceae。分析表明，Mimulicalyx属为苔科Mimuleae族的一员。进一步讨论了Phrymaceae内属级系统发育关系，并提供了目前公认的15个属的二叉检索表。
Abstract. With the disintegration of the traditionally circumscribed Scrophulariaceae, the phylogenetic placements of most genera formerly placed in that family have been resolved. However, the familial placement of the monotypic genus Mimulicalyx has not been included in any published molecular phylogenetic study. Here, we adopt a two-step approach to resolve the phylogenetic placement of Mimulicalyx using three datasets: (1) a 71 619 bp plastome alignment of Lamiales; (2) a dataset of six plastid DNA regions (atpB, matK, ndhF, rbcL, rps16 and trnL-trnF) for Phrymaceae; and (3) a dataset of the nuclear ribosomal internal and external transcribed spacer regions (nrITS, ETS) for Phrymaceae. Our analyses reveal that Mimulicalyx is a member of the tribe Mimuleae in Phrymaceae. Generic level phylogenetic relationships within Phrymaceae are further discussed, and a dichotomous key to the 15 genera currently recognized is provided.
