Palynotaxonomy of the genus Gladiopappus (Dicomeae, Asteraceae) with special emphasis on the exine ultrastructure and mesoapertures [PDF]

open access: yesBlumea - 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 ...

Morphology and ultrastructure of Tilioideae pollen: how to differentiate Craigia, Mortoniodendron, and Tilia [PDF]

open access: yesBotanical Studies
Assigning fossil Tilioideae pollen grains to the extant genera Craigia, Mortoniodendron, and Tilia is difficult. Firstly, the pollen from these genera appears similar when studied only with light microscopy.

Palynotaxonomy of the cretaceous to neogene section of the pelotas basin, Brazil: Dinoflagellate cysts of peridiniales order [PDF]

open access: yes, 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 ...

Does palynotaxonomy contribute to the systematics of the genus? The section Multicaulia of the genus Hedysarum (Fabaceae) example in Türkiye

open access: yesActa Botanica Croatica
The purpose of the current work was to assess the systematic and taxonomic significance of the pollen morphological characteristics of the Multicaulia section of Hedysarum species found throughout Türkiye using scanning electron microscopy (SEM) and light microscopy (LM) techniques.

Palynotaxonomy of the cretaceos to neogene section of the pelotas brasin, brasil: Dinoflagellate cysts of ptychodiscales and gonyaulacales orders [PDF]

open access: yes, 2018
Cistos de dinoflagelados são comumente utilizados para a obtenção das idades relativas, correlações e interpretações paleoambientais das seções cretáceas e paleógenas da margem continental brasileira. Contudo, as informações micropaleontológicas da Bacia de Pelotas são referentes, na sua maioria, a microfósseis calcários.
