The Stipeae tribe is a group of 400−600 grass species of worldwide distribution that are currently placed in 21 genera. The ‘needlegrasses’ are characterized by having single-flowered spikelets and stout, terminally-awned lemmas. We conducted a molecular phylogenetic study of the Stipeae (including all genera except Anemanthele) using a total of 94 species (nine species were used as outgroups) based on five plastid DNA regions (trnK-5’matK, matK, trnHGUG-psbA, trnL5’-trnF, and ndhF) and a…

Stipa (Poaceae) and allies in the Old World: molecular phylogenetics realigns genus circumscription and gives evidence on the origin of American and Australian lineages
TLDR
109 new ingroup taxa with a focus on Old World Stipeae are studied using chloroplast and nuclear ribosomal DNA sequences, and taxonomic key characters are discussed.
A phylogeny and classification of the Muhlenbergiinae (Poaceae: Chloridoideae: Cynodonteae) based on plastid and nuclear DNA sequences.
TLDR
The phylograms suggest that Muhlenbergia originated in North America because the sister (Sohnsia filifolia and Scleropogoninae) is composed of predominantly North American species.
Molecular phylogenetic analyses and classification of the Pooideae (Poaceae) - [kumulative Dissertation]
TLDR
The results do not reveal a significant role of past hybridisation, plastid lineage sorting or reticulation in the evolutionary diversification of the major lineages of the grass subfamily Pooideae and a largely well-supported pattern of divergence is results in.
Phylogenetics of Piptatherum s.l. (Poaceae: Stipeae): Evidence for a new genus, Piptatheropsis, and resurrection of Patis
TLDR
A phylogenetic analysis of 53 species that have been associated with the Oryzopsis/Piptatherum complex using four plastid regions in combination with lemma micromorphology to infer evolutionary relationships is conducted and a new genus, Piptatheropsis, is proposed to include five North American species.
Molecular phylogenetics and micromorphology of Australasian Stipeae (Poaceae), and the interrelation of whole-genome duplication and evolutionary radiations in this grass tribe
TLDR
These genera are most abundant in Central and Eastern Asia, which makes a colonization of Australian and New Zealand from this region more likely, perhaps via long-distance dispersal, than colonization of Australia from southern South America via Antarctica as previously invoked.
Molecular Phylogenetics and Micromorphology of Australasian Stipeae (Poaceae, Subfamily Pooideae), and the Interrelation of Whole-Genome Duplication and Evolutionary Radiations in This Grass Tribe
TLDR
A rather coherent picture of chromosome number variation underlines the enormous phylogenetic and evolutionary significance of this frequently ignored character.
Duthieeae, a new tribe of grasses (Poaceae) identified among the early diverging lineages of subfamily Pooideae: molecular phylogenetics, morphological delineation, cytogenetics and biogeography
TLDR
Morphological, cytogenetic and biogeographical analyses point to warm and humid conditions as the ancestral bioclimatic niche of Phaenosperma and Duthieeae, whereas adaptation to cold and drought occurred only in a part of DuthIEeae but was obviously less successful than in the widespread and much more species-rich tribe Stipeae.
An expanded phylogenetic analysis of Austrostipa (Poaceae: Stipeae) to test infrageneric relationships
TLDR
A phylogeny of the Australasian grass genus Austrostipa is determined and the inferred phylogeny hints at gene duplication, chloroplast capture, or deep coalescence in the evolutionary history of Aust Frostipa.

A Phylogeny of Piptochaetium (Poaceae: Pooideae: Stipeae) and Related Genera Based on a Combined Analysis Including Trnl-f, Rpl16, and Morphology
TLDR
Monophyly of Piptochaetium was confirmed by morphological and total evidence (morphological and DNA data) analyses, and relationships among species of this genus and allied genera of Stipeae were analyzed.
MOLECULAR PHYLOGENETIC ANALYSIS OF THE AMERICAN STIPEAE (POACEAE) RESOLVES JARAVA SENSU LATO POLYPHYLETIC: EVIDENCE FOR A NEW GENUS, PAPPOSTIPA
TLDR
Pappostipa is monophyletic and not closely related to other sampled species of Jarava, supporting recognition of the new genus Pappost ipa speciosa, and two clades that are identified as new sections are identified.
Phylogenetic Relationships of the Genus Piptochaetium (Poaceae, Pooideae, Stipeae): Evidence from Morphological Data
TLDR
A systematic treatment of the entire genus Piptochaetium, which complements that of Cialdella and Arriaga for the South American species, is presented herein and a phylogenetic hypothesis for the genus is proposed based on morphological and anatomical characters.
Paraphyly of Tarasa (Malvaceae) and Diverse Origins of the Polyploid Species
TLDR
It is suggested that the unusual morphological features of the tetraploids are the result of convergent evolution and not shared ancestry, and neither the nuclear nor the chloroplast phylogeny supports monophyly of Tarasa as currently circumscribed.
Systematics of the Tribe Stipeae (Gramineae) Using Molecular Data
Internal transcribed spacer (ITS) sequences have been determined for a wide range of stipoid grasses (Poaceae, Pooideae, Stipeae). Nardus was confirmed as the most appropriate outgroup. Anisopogon is
Phylogeny and biogeography of Juglans (Juglandaceae) based on matK and ITS sequence data.
TLDR
These analyses consistently supported Juglans as a monophyletic group and as the sister group to the genus Pterocarya and the fossil record suggests that the butternuts had evolved by the early Oligocene in North America.
A phylogenetic analysis of Poaceae, tribe Poeae sensu lato based on morphological characters and sequence data from three plastid-encoded genes: evidence for reticulation, and a new classification for the tribe
TLDR
Results suggest the possibility of wide hybrid origins for some groups, especially the subtribe Airinae, with all previously recognised tribes subsumed within a broadly circumscribed Poeae sensu lato, in which accepted genera are accommodated in 21 subtribes.
A PRELIMINARY PHYLOGENETIC ANALYSIS OF THE GRASS SUBFAMILY POOIDEAE (POACEAE), WITH ATTENTION TO STRUCTURAL FEATURES OF THE PLASTID AND NUCLEAR GENOMES, INCLUDING AN INTRON LOSS IN GBSSI
TLDR
The results support a novel set of relationships among Ihe tribes of Pooideae, including the placement of Brachypodieae, Bromeae, Triticeae, and Poeae s.l. within a clade for which a three-nucleotide inversion in ndhF is interpreted as a synapomorphy.
Resurrection and emendation of Macrochloa (Gramineae: Stipeae)
TLDR
Morphological and anatomical arguments are presented for recognizing one new genus, Celtica, and one previously described genus, Macrochloa, in the Stipeae, and formal presentation of the generic name Celtica plus combinations for its subspecies, including one newly described subspecies.
LOS GÉNEROS NATIVOS DE LA TRIBU STIPEAE (POACEAE, POOIDEAE) EN CHILE THE NATIVE GENERA OF THE TRIBE STIPEAE (POACEAE, POOIDEAE) IN CHILE
TLDR
New morphological characters primarily these of spikelets, anatomical leaves, embryological characters, epidermis patterns of lemma and molecular data have lead to a more natural delimitation of genera of the tribe Stipeae (Pooideae, Poaceae).
