dc.description.abstract | In the context of recent molecular phylogenies
of the basal grades of Compositae, we investigated the
utility of pollen morphology within the tribe Gochnatieae.
The pollen of 64 species of Anastraphia, Cnicothamnus,
Cyclolepis, Gochnatia, Pentaphorus, and Richterago was
studied using light microscopy and scanning electron
microscopy. In addition, three extra-Gochnatieae genera
(Ianthopappus, Leucomeris, and Nouelia) were examined
as they were traditionally morphologically related to
members of the tribe Gochnatieae. Three of the species of
Gochnatieae were examined using transmission electron
microscopy. Two pollen types, and two new subtypes, have
been recognized on the basis of the pollen shape, size, and
exine sculpture. The pollen features of Gochnatia sect.
Moquiniastrum and G. cordata are similar and distinctive
within the genus and support the recently re-circumscribed
section Hedraiophyllum. Within the species with echinate
pollen surface, the distinctive spine length of Anastraphia
supports its recent resurrection as a genus. The identity of
Pentaphorus could not be supported by pollen features as
was for other morphological characteristics. The pollen
features shared across Cyclolepis, Ianthopappus, Leucomeris,
Nouelia and Gochnatia sect. Moquiniastrum, as
well as those shared by Richterago and Anastraphia could
be a result of parallel evolution. | pt_BR |
