Flower and Spikelet Construction in Rapateaceae (Poales) [PDF]
Frontiers in Plant Science, 2022 The family Rapateaceae represents an early-divergent lineage of Poales with biotically pollinated showy flowers. We investigate developmental morphology and anatomy in all three subfamilies and five tribes of Rapateaceae to distinguish between ...

Understanding evolution in Poales: Insights from Eriocaulaceae plastome.
PLoS ONE, 2019 In this study, we report the plastome of Eriocaulon decemflorum (Eriocaulaceae) and make an effort to understand the genome evolution, structural rearrangements and gene content of the order Poales by comparing it with other available plastomes. The size

Paepalanthus rectifolius, a new name in Eriocaulaceae (Poales)
PhytoKeys, 2012 Syngonanthus weddellii var. gracilis Moldenke (1973) was described very briefly based on a single collection. A careful analysis reveals that this variety has dimerous flowers, free petals of the pistillate flower and bifid stigmatic branches.

The megagametophyte in Anarthria (Anarthriaceae, Poales) and its implications for the phylogeny of the Poales [PDF]
American Journal of Botany, 1993 The development and structure of the megagametophyte of Anarthria (Anarthriaceae), Aphclia, and Centrolepis (Centrolepidaceae) are described. Anarthriaceae has tenuinucellate ovules and the Polygonum type of megagametophyte development, both characters typical of the Poales.

Up on the table mountains in Brazil: new Bromeliaceae and Eriocaulaceae (Poales) from the Pantepui in the Guayana Shield [PDF]
Plant Ecology and Evolution, 2018 Background and aims – As “islands in the sky” of northern South America, the isolated ecosystems of the Pantepui province include a distinct flora with high levels of endemism and which are ancestral areas for many angiosperm lineages. About one fifth of
