Abstract
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.
