Sequences of rbcL and ndhF were analysed independently and in combinat
ion to resolve phylogenetic relationships in Labiatae s. 1. Monophyly
of Labiatae s. 1 was supported by all three analyses. Congea tomentosa
(Symphoremataceae) is nested within Labiatae s. 1. in the rbcL analys
is, but emerges as the sister group of Labiatae s. 1. in the ndhF and
combined analyses. Four noteworthy clades of Labiate s. 1. also are su
pported by all analyses corresponding to subfamilies Nepetoideae, Lami
oideae, Pogostemonoideae and Scutellarioideae. Monophyly of subfamilie
s Chloanthoideae and Viticoideae is not supported. A clade comprising
Teucrioideae plus Ajuga is supported by ndhF and the combined analysis
.
