“…We verified that the quantitative data in some cases could help distinguish the species, as in Galipea jasminiflora (with large pollen grains) and Metrodorea nigra (among colporate species that also have larger pollen grains). For Rutaceae, as well as in other families also analyzed in forest fragments (Souza & Gasparino 2014;Belonsi & Gasparino 2015), qualitative data are the main tools in pollen species distinction.…”

“…Pollen studies on native species from remaining forest fragments indicate variations in shape, aperture, amb, ornamentation and size of the pollen grain (Souza & Gasparino 2014;Belonsi & Gasparino 2015), so the aim of this study is to identify morphological characteristics in pollen grains of the Rutaceae species which may be used for future taxonomic and palynological studies contributing to the conservation of these species in priority conservation areas.…”

This paper presents pollen morphology of 12 native Brazilian species of Rutaceae from forest fragments of São Paulo, Brazil. The aim of this research is to expand the morphological knowledge of the species, thus contributing to taxonomic knowledge and, subsequently, conservation of species and the forest area. The pollen grains were acetolyzed, measured, described qualitatively, and illustrated using light microscopy (LM) and scanning electron microscopy (SEM). The studied species have differences in polarity, size, shape, aperture and exine ornamentation of the pollen grains, confirming the eurypalynous character of Rutaceae pollen. In particular, species of Zanthoxylum L. also presented significant differences in the pollen grains, confirming the morphological variation within the genus. The quantitative data and multivariate analysis confirm the morphological description; thus, the results reinforce the importance of pollen morphology in the identification and characterization of species of Rutaceae.

“…However, morphological studies rarely describe the pollen types for the family, which could help in the morphological grouping of genera and species. Thus, the aim of this work was to identify pollen types in Sapindaceae and to expand the morphological knowledge of the analyzed species from Brazilian forest fragments, increasing the studies on pollen conducted for the area (Souza & Gasparino 2014;Belonsi & Gasparino 2015;Dutra & Gasparino 2018;Landi &Souza et al 2019).…”

“…Continuing the pollen morphology characterization for forest fragments areas (Souza and Gasparino 2014), the aim of this study is to contribute with morphological data, which will be used in future taxonomic or pollinic studies (such as geopalynology, melissopalynology, etc.) that include Malpighiaceae species and assisting so their conservation.…”

The pollen morphology of 12 Brazilian native species of Malpighiaceae from forest fragments was investigated in search to expand the morphological knowledge of the species analyzed thus contributing to its palynology, taxonomy, and conservation. The pollen grains were acetolysed, measured, photographed using light microscopy and scanning electron microscopy, and described qualitatively. The quantitative data were analyzed by descriptive statistics and multivariate statistics. The pollen grains are monads, apolar or isopolar, small to large, with circular to quadrangular amb, oblate-spheroidal to prolatespheroidal, tricolporate with long colpi and lalongate endoaperture or 6-(7-8)-porate with or without colpoids and aspides, psilate-rugulate, rugulate or microreticulate exine, sexine thicker than nexine in most species. The results of this study point to differences in the morphology of the pollen grains in the analyzed species, which indicates Malpighiaceae as a eurypalynous family; this fact was also confirmed by quantitative data and the multivariate analysis. These data reinforce the importance of pollen morphology for identification and distinction of genus and species of the family.
