Phylogeny of the Paniceae (Poaceae: Panicoideae): integrating plastid DNA sequences and morphology into a new classification
TLDR
With this extensive sampling, the phylogenetic relationships and the assignation of synapomorphies are resolved, and the support in subtribe sorting is improved, consequently a robust circumscription of the tribe Paniceae s.l. is proposed.
Phylogeny of Nassella (Stipeae, Pooideae, Poaceae) Based on Analyses of Chloroplast and Nuclear Ribosomal DNA and Morphology
TLDR
The DNA data alone and combined with morphology showed Nassella to be paraphyletic with respect to a monophyletic Amelichloa, and none of the groups previously circumscribed as subgenera of Stipa, that are now considered to be composed of species in NassellA, were recovered as monophylete.
Phylogeography and palaeodistribution modelling in the Patagonian steppe: the case of Mulinum spinosum (Apiaceae)
TLDR
An integrative study of the endemic, yet ubiquitous, Patagonian shrub Mulinum spinosum (Apiaceae) was performed to assess the historical processes that influenced its geographical pattern of genetic variation and model its extant and palaeoclimatic distributions to assess support for the phylogeographical patterns recovered.
Phylogenetic Studies in the Paniceae (Poaceae): a Realignment of Section Lorea of Panicum
TLDR
Two new genera are proposed and described: Apochloa and Renvoizea, which are restricted to the Guiana highlands and eastern Brazil, and did not support the monophyly of Panicum section Lorea.
Phylogenese Studies in the Paniceae (Poaceae-Panicoideae): Ocellochloa, a New Genus from the New World
TLDR
A phylogenetic analysis of Paniceae based on cpDNA sequence data (ndhF) was performed with special emphasis on section Stolonifera of Panicum, resulting in Ocellochloa being described as a new genus.
Oncorachis and Sclerochlamys, two new segregated genera from Streptostachys (Poaceae, Panicoideae, Paniceae): a revision based on molecular, morphological and anatomical characters.
TLDR
Two new genera are proposed, Oncorachis based on Streptostachys macrantha and S. ramosa and Sclerochlamys for Streptstachys rigidifolia, and the phylogenetic position of the new generA and Streptosterachys within Paniceae is evaluated.
Mycorrhizal compatibility and symbiotic reproduction of Gavilea australis, an endangered terrestrial orchid from south Patagonia
TLDR
A low mycorrhizal specificity of G. australis is suggested and a better knowledge of the biology of this orchid as well as of other sympatric Patagonian orchid species, all of them currently under serious risk of extinction are contributed.
Phylogenetic relationships within Turneraceae based on morphological characters with emphasis on seed micromorphology
TLDR
The formation of a floral tube conferred an evolutionary advantage to the Turneraceae, because it developed in 66 % of the genera, and the analyses suggest that all genera are monophyletic.
