Familia: Poaceae
Subfamilia: Pooideae
Tribus: Poeae
Subtribus: incertae sedis
Genera: Avenula (sensu strictu p.p. typica A. pubescens; syn. -- Homalotrichon; excluding Helictochloa. Avenula s.s. is a floater, possibly allied to the set of Coleanthinae, Poinae s.l., Miliinae, Phleinae).

DAD clade {hybrid between an ancient taxon allied to Alopecurinae and an ancient Poodinae taxon sensu Soreng et al. 2015}: Arctophila, Dupontia, Dupontiopsis
HSAQN clade {Gillespie et al. 2010, Kellogg 2015}: Arctagrostis, Hookerochloa (syn. – Festucella), Nicoraepoa {one known hybrid with Poa}, Saxipoa, Sylvipoa.
Nothogenera: × Arctodupontia – × Dupoa

Name

Poeae incertae sedis
Note: Phylogenetically these genera are Poodinae incertae sedis (Soreng et al., 2017), but WS dose not recognise supersubtribes as a taxon.
