Floral development and vascularization help to explain merism evolution in Paepalanthus (Eriocaulaceae, Poales) [PDF]
PeerJ, 2016 Background Flowers in Eriocaulaceae, a monocot family that is highly diversified in Brazil, are generally trimerous, but dimerous flowers occur in Paepalanthus and a few other genera.

Ecology and Evolution, Volume 13, Issue 7, July 2023., 2023 Daily observations, an experimental greenhouse trial, and time‐lapse photography of Ripariosida hermaphrodita flowers showed that anthers that were purple, open, and shedding pollen became beige colored and tightly closed after rainfall. To our knowledge, our work represents the first report of anther closure in response to rain in the Cotton Family ...

Accidental epiphytes: Ecological insights and evolutionary implications
Ecological Monographs, Volume 92, Issue 4, November 2022., 2022 Abstract Vascular epiphytes are an important component of many ecosystems and constitute a substantial part of global plant diversity. In this context, accidental epiphytism, that is, the opportunistic epiphytic growth of typically terrestrial species, deserves special attention because it provides crucial insights into the global distribution of ...

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.

Population Ecology, Volume 64, Issue 2, Page 80-92, April 2022., 2022 This review analyzed the main dispersion indices and coefficients published between 1915 and 1975 and applied to the analysis of the spatial distribution of plant species. Despite a long history in ecological studies, these measurements do not meet the growing interest of ecologists in identifying factors related to distribution patterns.
