Abstract
A phylogenetic study was conducted of species of
Halymeniaceae from New Zealand presently placed
in Aeodes or Pachymenia, based on maximum-likelihood
(ML), maximum-parsimony (MP), and Bayesian
analyses of rbcL and nuclear internal transcribed
spacer (ITS) rDNA sequences. We used molecular
and morphological data in combination with exhaustive
sampling of herbarium collections to clarify the
taxonomy and distributions of New Zealand members
of Pachymenia and Aeodes. Our study confirms
the presence of three erect species of Pachymenia
on the New Zealand mainland, and we resurrect the
name Pachymenia dichotoma J. Agardh for the widely
distributed, southernmost species. Species of Aeodes
from South Africa are shown to be closely related to
Pachymenia carnosa (J. Agardh) J. Agardh, the type
species of Pachymenia, and are accordingly transferred
to Pachymenia.
