Within Poales, the clade (Poaceae, Ecdeiocoleaceae, Joinvilleaceae) has previously received robust support from DNA sequence data from a range of genes. However, the question of which family (or set of families) is the sister group of Poaceae has not been answered with any degree of confidence, to date. Using Ecdeiocolea monostachya as the only representative of its family, other researchers have found the clade to resolve (although mostly with low levels of support) as (Joinvillea (Ecdeiocolea…

Features in the complete plastome of Anomochloa marantoidea (Poaceae) were investigated, finding that the crown node of this species diverged before those of any other grass subfamily and is atypically short with no evidence of the ψrpl23 locus found in all other Poaceae.

The results of an initial project by the Monocot AToL (Angiosperm Tree of Life) team on phylogeny and evolution in Poales are presented, using sequence data for 81 plastid genes from 83 species of angiosperms and recovered highly concordant relationships using maximum likelihood (ML) and maximum parsimony (MP).

This study highlights the presence of a pollen-tube transmitting tissue (PTTT) or solid style in the gynoecium of Flagellaria, as also in many Poaceae, but not in Joinvillea or Ecdeiocoleaceae.

Estimates for deep divergences among grasses were older than previous such estimates, likely influenced by more complete taxonomic and molecular sampling and the use of recently available or previously unused fossil calibration points.

Analysis of the morphological and molecular data places Poaceae in an unresolved relationship relative to several other taxa, including Joinvillea and Ecdeiocolea, while analysis of the molecular and combined data resolves Ec deiocolesa as sister of Poaceae, with joinvillea the sister of this group.

Comparisons of sister-group comparisons indicate that some characteristic grass features, notably the scutellum, do not occur in their putative closest relatives and that more data is needed on early-diverging grass genera to resolve issues.

Higher basic chromosome numbers are maintained in basal taxa of all grass subfamilies, whereas smaller numbers are found in terminal species, which refutes the 'secondary polyploidy hypothesis', but partially supports the 'reduction hypothesis' previously proposed for chromosomal evolution in the Poaceae.
