Floral Anatomy of Paepalanthoideae (Eriocaulaceae, Poales) and Their Nectariferous Structures. [PDF]
Annals of Botany, 2007 Eriocaulaceae (Poales) is currently divided in two subfamilies: Eriocauloideae, which comprises two genera and Paepalanthoideae, with nine genera. The floral anatomy of Actinocephalus polyanthus, Leiothrix fluitans, Paepalanthus chlorocephalus, P. flaccidus and Rondonanthus roraimae was studied here. The flowers of these species of Paepalanthoideae are

Evolutionary History of Poales
Annual Review of Ecology, Evolution, and Systematics, 2005▪ Abstract The predominantly wind-pollinated order Poales includes about one third of all monocot (Angiosperm) species, with c. 20,000 species dominating modern savanna and steppe vegetation. Recent improvements in understanding relationships within the order allow phylogenetic optimizations of habitat preferences and adaptive ...

Comparative embryology and taxonomic considerations in Eriocaulaceae (Poales)
Feddes Repertorium, 2010AbstractThe genus concept within Eriocaulaceae is widely discussed because it is mainly based on a small number of floral characteristics of unknown functional and evolutionary significance. The aim of the present work is to comparatively study the embryology of representatives of most genera of Eriocaulaceae to identify relevant features that might ...

Contribution to the embryology of Leiothrix fluitans (Eriocaulaceae: Poales)
Aquatic Botany, 2007Abstract This paper presents a contribution to the understanding of the embryology, especially microsporogenesis, the antipodal cell behavior, and the early stages of the micropylar seed operculum, in Leiothrix fluitans, to elucidate these aspects both within the subgenus Rheocaulon and within the genus in Eriocaulaceae.

Pollination biology of Syngonanthus elegans (Eriocaulaceae – Poales)
Australian Journal of Botany, 2009Studies on the pollination biology of Eriocaulaceae are scarce although particularly interesting because of its inclusion in the Poales, a predominantly wind-pollinated order. The pollination biology of Syngonanthus elegans (Bong.) Ruhland was studied during two annual flowering periods to test the hypothesis that insect pollination was its primary ...

Pollen morphology of Poaceae (Poales) in the Azores, Portugal
Grana, 2015AbstractThe objective of this study was to expand knowledge on the Poaceae and morphologically describe pollen grains of species occurring in the Azores Archipelago, Portugal. Pollen grains from each species under study were subjected to standard acetolysis, mounting of at least three permanent slides of each species for observations and measurement of

Stomata are mobile epidermal valves that regulate CO₂ uptake at the cost of water loss in response to changes in light, CO₂, vapor pressure deficit (VPD), and other signals. Variation in stomatal function across species can have a significant impact on plant function; however, this variation is often examined within major land plant lineages or within ...

The Evolutionary History of the Poales/Restionales: A Hypothesis
Kew Bulletin, 1987The existing hypotheses on the phylogeny of the families of the Poales are reviewed, and the data on which they are based are critically assessed. The results of this assessment are presented as a cladogram. The fossil pollen record of the order is also reviewed, and many of the results are reinterpreted.

Putative neofunctionalization of a Poales-specific EXO70 clade
Abstract EXO70s are uniquely expanded in land plants compared to all other eukaryotic lineages. The functional implications of this expansion and diversification on the conserved role of EXO70 as a subunit of the octameric exocyst complex have remained ...Molly Bergum +14 more
