The phylogeny of the genus Nassauvia and closely related genera was reconstructed using sequences from the internal transcribed spacer regions (ITS) of nuclear ribosomal DNA. The genus Triptilion is nested within Nassauvia, making the latter genus paraphyletic. Neither of the two subgenera Nassauvia and Strongyloma is resolved as monophyletic, and none of the sections of subgenus Nassauvia is recovered as monophyletic. The evolution of the compound secondary inflorescences has been complex in… 

Phylogenetic reconstruction of the genus Triptilion (Asteraceae, Nassauvieae) based on nuclear and chloroplast DNA sequences

The results of the life history reconstructions indicate that the common ancestor of Triptilion and Nassauvia was perennial, and the annual habit appears to be derived in Triptillion.

Phylogenetic reconstruction of the South American genus Leucheria Lag. (Asteraceae, Nassauvieae) based on nuclear and chloroplast DNA sequences

The hypothesis that the ancestor of Leucheria would have originated in a forested habitat is examined and the validity of nine morphologically defined evolutionary lines recognized in earlier work on the genus is examined.

Phylogeography and palaeodistribution modelling of Nassauvia subgenus Strongyloma (Asteraceae): exploring phylogeographical scenarios in the Patagonian steppe

Assessment of demographic processes and historical events that shaped current geographic patterns of haplotypic diversity; analyze hypotheses of isolation in refugia, fragmentation of populations, and/or colonization of available areas during Pleistocene glaciations; and model extant and palaeoclimatic distributions to support inferred phylogeographical patterns.

Geographic Variation among Closely Related, Highly Variable Species with a Wide Distribution Range: The South Andean-Patagonian Nassauvia subgenus Strongyloma (Asteraceae, Nassauvieae)

Despite an association between morphological variation with geography and climate, actual geographic distributions of the putative species did not entirely match the clinal pattern of morphology, geography, and climate.

Nassauvia falklandica (Compositae: Mutisieae: Nassauviinae), a new endemic species for the Falkland Islands

A new endemic herbaceous sub-shrub from the Falkland Islands, N. falklandica is unique within the genus in possessing a row of pits towards the apex of the abaxial surface of its leaves; stomata and stiff white hairs are confined to these pits.

Consideraciones sobre la sistemática de las familias y los géneros de plantas vasculares endémicos de Chile Systematic considerations of Chilean endemic vascular plant families and genera

This study aims at discussing modifications in taxonomy and contributing to the correct delimitation of endemic genera, using updated databases and bibliographic sources and emphasizing the discussion on those genera with ambiguous classification status.

The road to 2020 targets and the learnings from the emblematic South American plant genus Nassauvia (Asteraceae)

It is identified a future dramatic loss of Nassauvia species in the Andes and conversely a species increase in Patagonia, which has emerged as the cradle of the genus and could be its refuge in the future according the predictions targeted by climate change.

Exploring adaptation in a key Australian genus Brachyscome through experimentation

This paper presents the results of three experiments on the basis of which three hypotheses, Habitat Specialization Versus Performance in Australian Alpine Daisies and Range Size Hypothesis were chosen, were determined.



Evolution of secondary heads in Nassauviinae (Asteraceae, Mutisieae).

It is shown that the ancestor of Moscharia, Polyachyrus, and Leucheria, in a more arid habitat, had a complex type of secondary head, and loss of complexity occurred in response to a shift from arid to mesic conditions.

A cladistic analysis of Nassauvia Comm. ex Juss. (Asteraceae, Mutisieae) and related genera

Nassauvia, Triptilion, and Calopappus form a monophyletic group diagnosed by the following synapomorphies, and subgenus Strongyloma appears as the most primitive taxon, with its spicate conflorescence, whereas section Mastigophorus with its solitary capitulum is thought-derived.

Phylogeny and evolution of Perezia (Asteraceae: Mutisieae: Nassauviinae)

A molecular phylogenetic analysis of most of the species of Perezia reveals that the genus is not monophyletic with two species more closely related to Nassauvia than to Perezia, and that Burkartia (Perezia) lanigera is related to Acourtia and is the only member of that clade in South America.

A typological analysis of the inflorescences of the genus Nassauvia (Asteraceae)

Inflorescences currently described as „pseudocephalia” are shown to be strongly condensed panicles or stachyoids of heads and sister group inspection suggests the condensed panicle of heads to be the basal inflorescence condition within the genus Nassauvia.

Amplification and direct sequencing of fungal ribosomal RNA genes for phylogenetics

Chemotaxonomic studies in the Saxifragaceae s.l. 4. The flavonoids of Heuchera micrantha var. diversifolia

Methods combining column and thin-layer chromatography are described which are generally useful for analysis of complex mixtures of polyphenolic compounds.

A new species of the South American genus Nassauvia (Compositae: Mutisieae) from Chilean Patagonia

The distinctive pappus of Nassauvia coronipappa may be related to selection, in harsh alpine habitats, against dispersal away from nurse sites.

El género Calopappus (Compositae, Mutisieae)

The suffrutex genus Calopappus of Compositae (Mutisieae, Nassauviinae) from central Chile that contained hitherto two species is considered in this study as a monotypic genus. The single species C.
