“…When dealing specifically with the focus of this work, Cabrera and Cuadrado (2001) analysed pollen morphology of Aureliana fasciculata in northeastern Argentina; Barth and Duarte (2008) examined A. fasciculata var. longifolia and Cruz-Barros and colleagues (2011) investigated Athenaea picta.…”

Aureliana and Athenaea (Withaniinae, Solanaceae) are two genera of shrubs or small trees with centres of diversity in the Brazilian Atlantic Rain Forest. They are difficult to distinguish using gross morphology, and are traditionally segregated based on differences in fruiting calyx size. Pollen grains of all taxa were acetolysed, treated and examined with light and scanning electron microscopy, with the aim of identifying diagnostic characters. Microphotographs and illustrations of pollen grains are presented. The species analysed present small-to medium-sized monad pollen grains of varying morphology with long to extremely long colpi, and lalongate endoapertures. The analysis showed that the pollen grains of both genera are very similar, differing in size-related characters. These data contributed to the synonymisation of Athenaea within Aureliana.

“…The pollen samples were submitted to the acetolysis process. Three slides were prepared with glycerinated gelatin for each sample after the process (Barth & Duarte, 2008). The pollen grains were photomicrographed and identified in types, following a pollen catalog of cerrado plants (Bastos et al, 2008).…”

Bees Diversity on Flowers of Eremanthus spp. (Asteraceae)

et al. 2019

Bees are considered important pollinators due to their fidelity to plants, enabling the maintenance of gene flow between plant species. The objective of this study was to recognize the visit of bees in two Candeia species, Eremanthus erythropappus and Eremanthus incanus (Asteraceae), as well as to analyze the pollen content carried by bees in a regeneration area. Nine samplings were taken in each plant species using entomological nets. The pollen grains were obtained in 338 bees from their legs and bodies. The species Trigona spinipes, Apis mellifera, and Bombus pauloensis were most frequent. Candeias are essential in the study area because they have high adaptive potential, but besides them, other plants are also important for attracting bees searching for pollen and/or nectar.Melastomataceae, mainly Tibouchina sp., appear to be important sources of pollen. The presence, in greater quantity, of Bombus spp. in Eremanthus flowers probably occurs more by the demand for nectar, since the pollen frequency of other families such as Melastomataceae and Myrtaceae was higher. However, the use of Eremanthus spp. pollen is more frequent by A. mellifera and T. spinipes. CONCLUSIONS • The eusocial bees Bombus pauloensis, Trigona spinipes,and Apis mellifera were the ones with the highest occurrence in the two species of Eremanthus.• The pollen of Eremanthus spp. showed higher frequency in Trigona spinipes and Apis mellifera.

“…Os valores dos espécimes aqui medidos encontram-se dentro da faixa de variação do material citado por estes autores. Barth & Duarte (2008), ao estudarem os grãos de pólen de Acnistus arborescens, obtiveram resultados semelhantes aos encontrados no presente trabalho quanto às aberturas; no entanto, quantitativamente, os grãos de pólen descritos pelas autoras apresentaram diâmetros ligeiramente maiores (P = 33,1 µm (30-36) e E = 35,2 µm (32-37)) e a ornamentação foi definida como escabrada.…”

-(Pollen flora of "Reserva do Parque Estadual das Fontes do Ipiranga" (São Paulo, Brazil). Family: 136-Solanaceae). Pollen grains of 12 genera and 41 species of Solanaceae occurring in the "Reserva do Parque Estadual das Fontes do Ipiranga" were examined: Acnistus arborescens (L.) Schlecht., Athenaea picta (Mart.) Sendtn., Brunfelsia latifolia Benth., Brunfelsia pauciflora IntroduçãoEste trabalho faz parte do projeto elaborado por Melhem et al. (1984), que visa realizar a caracterização morfológica dos grãos de pólen das famílias ocorrentes na Reserva do Parque Estadual das Fontes do Ipiranga (PEFI), complementando assim os estudos taxonômicos realizados na mesma área, segundo
