Podostemaceae show different patterns of morphological variation relative
to molecular ones between genera and between species, but additional
material was necessary to make the patterns clearer. Using new material
collected from Cambodia, we compared the variations of Terniopsis
chanthaburiensis and T. heterostaminata in Cambodia, Laos and Thailand,
and conducted matK phylogenetic analysis with many samples and most
species of the genus. In contrast to the narrow molecular variation, the
morphological variation (e.g., in the length of the shoots and pedicels)
is large and continuous. The results indicate that variation in the two
species is intraspecific. A similar pattern exists in two pairs of other
species of Terniopsis, in which the morphological variation is large and
discontinuous, while there is little molecular difference. The opposite
pattern is present in other cases (e.g., Dalzellia zeylanica and Tristicha
trifaria). The variation in T. chanthaburiensis and T. heterostaminata
does not appear to be a response to variation in the habitats, that is
submerged rock surfaces in fast currents. Distributional and phylogenetic
data indicate that Terniopsis diversified primarily in Laos and Thailand,
then expanded into neighboring regions. A synopsis of the genus Terniopsis
and its 14 species is given.
