利用两个组合数据矩阵中5个区域（rbcL、ndhF、rps 16、trnL-F、nr ITS）的DNA序列数据，探讨了三节虫属与刺蛾属的系统发育位置。一个（rbcL，ndhF，rps 16）代表了广泛的抽样在大多数家庭的Lamiales。另一个数据矩阵代表了两个DNA区域，部分不可分辨的Lamiales（trnL-F，nr ITS）加上rps 16，这被证明是可变的，足以在Lamiales的较小分类水平上给出分辨率。岩生三条藻与列当属是姐妹类群，构成一个强支持分支，与列当科所有代表属都是姐妹属。此外，泡桐科和糙皮蕨科与列当科和木蕨属分支相邻。所有上述分类群仅与玄参科和/或车前草科（感觉APG II）有远亲关系。通泉草属和兰恰属应排除在Phrymaceae之外。这一结果与植物化学等资料相一致，为进一步研究唇形科植物的性状演化提供了框架。
Phylogenetic placement of Triaenophora together with Rehmannia were explored with DNA sequence data from five regions (rbcL, ndhF, rps16, trnL-F, nr ITS) in two combined data matrices. One (rbcL, ndhF, rps16) represented a wide sampling across most families of Lamiales. The other data matrix represented two DNA regions partly unalignable across Lamiales (trnL-F, nr ITS) plus rps16, which proved to be variable enough to give resolution at a smaller taxonomic level in Lamiales. Triaenophora rupestris and Rehmannia are sister taxa, composing a strongly Supported clade, which is sister to all representative genera of Orobanchaceae. Furthermore, Paulowniaceae and Phrymaceae are next to Orobanchaceae and Triaenophora-Rehmannia clade. All of the above taxa are only distantly related to Scrophulariaceae and/or Plantaginaceae (sensu APG II). Mazus and Lancea would be excluded from Phrymaceae. The resulting phylogeny is in agreement with other data Such as phytochemistry and provides a framework for further investigation of character evolution in Lamiales.
