Palynotaxonomy of Neotropical species ofDioscoreaL. (Dioscoreaceae)
Palynology, 2020 Nineteen Neotropical species of the genus Dioscorea L. were subjected to palynological analysis with the objectives of increasing palynological knowledge and identifying characteristics with taxonomic and phylogenetic value. More specifically, the aim was to identify characters that distinguish species and help to resolve relationships among New World ...

Palynotaxonomy of Calea sect. Meyeria (Asteraceae: Neurolaeneae)
Palynology, 2023 Calea comprises 157 species that occur in the Neotropics. The genus is organized into eight subgenera and 18 sections. Calea sect. Meyeria consists of eight species occurring exclusively in south-central Brazil. In this study, pollen grains from these eight species were sampled from herborized flower buds in pre-anthesis. Pollen samples were acetolyzed,

Palynotaxonomy of the genus Gladiopappus (Dicomeae, Asteraceae) with special emphasis on the exine ultrastructure and mesoapertures [PDF]
Blumea - Biodiversity, Evolution and Biogeography of Plants, 2018 The pollen morphology of Gladiopappus vernonioides was studied with transmission (TEM) and scanning (SEM) electron microscopy and with light microscopy (LM). An Anthemoid pattern of exine ultrastructure was found. The pollen morphology of Gladiopappus supports the inclusion of this genus in the tribe Dicomeae and subtribe Dicominae but not in the ...

Palynotaxonomy of the cretaceous to neogene section of the pelotas basin, Brazil: Dinoflagellate cysts of peridiniales order [PDF]
, 2017 Major part of micropaleontological knowledge of the Pelotas Basin is related to calcareous microfossils, justifying a systematic survey on the palynological data. This paper presents the taxonomic results from the study of 535 stratigraphic samples of two wells drilled in the offshore portion of the Pelotas Basin, enclosing Cretaceous to Neogene ...
