“…Silveira-Júnior et al (2012) observed that pollen grains of Richardia grandiflora were large-sized and suboblate, differing from our present observations. For Myrtaceae, our observations for Psidium guajava agree with the descriptions provided by Corrêa et al (2018) in their small size and oblate shape.…”

The aim of this study was to identify plant species visited by Apis mellifera L. in honey producing areas with typical Caatinga vegetation in the State of Bahia, as well as morphologically characterize pollen grains of the most representative species. Flowering specimens were collected from both areas, herborized, identified and deposited at the HUNEB herbarium. Analyses of floristic similarities were performed between eleven municipalities close to the study areas. Pollen was collected from all specimens, acetolyzed, measured, statistically analyzed, morphologically described, and photographed in light microscopy. Of the total of species recorded, 67.46 % were regarded as having beekeeping importance, with the richest botanical families being Fabaceae, Malvaceae and Asteraceae. Additionally, 37.5 % of the recorded species were herbs. The analyzed municipalities showed 84 % of floristic similarity. Of the total species recorded with visits by A. mellifera, 25.52 % had their pollen grains already described in the literature as monads, tetrads and polyads; isopolar, apolar and heteropolar; and mostly prolate spheroidal shape. Sizes varied from small to large, and the amb circular was predominant. The exine ornamentation was greatly diversified, varying from psilate to echinate. The obtained data corroborate the palynological knowledge of plants regarded as having beekeeping importance within the Caatinga.

“…Our main goal is to investigate whether pollen attributes could be useful for species distinction within the genus. Based on previous pollinic studies within Myrtaceae (Barth and Barbosa 1972;Thornhill et al 2012aThornhill et al , 2012bThornhill et al , 2012cThornhill et al , 2012dTuler et al 2017;Corrêa et al 2018), we expect exine ornamentation, size and shape to be the most efficient pollen characters for distinguishing species or groups of species within Campomanesia.…”

(Tuler et al 2017), another genus of Pimentinae within Myrtaceae. However, few species of Campomanesia have had their pollen grain morphology described in the literature (Barth and Barbosa 1972; Thornhill et al 2012d; Corrêa et al 2018). Therefore, the role of pollen morphology in the taxonomy of Campomanesia remains poorly understood.…”

“…Pollen grain size and exine ornamentation were found to be the most useful pollen characters for distinguishing species of Psidium (Tuler et al 2017). Differences in exine ornamentation and colpus size were informative to distinguish five of 35 species circumscribed under Campomanesia in the key provided by Corrêa et al (2018). The question of whether these same characters are useful for distinguishing a larger sample of species of Campomanesia remains unanswered.…”

“…Pollen grain descriptions are available for 10 species of Campomanesia (Barth and Barbosa 1972; Thornhill et al 2012d; Corrêa et al 2018). Some of these descriptions were provided within treatments of pollen floras (Salgado-Labouriau 1973; Corrêa et al 2018) or were included in large comparative studies of pollen morphology of the family Myrtaceae (Barth and Barbosa 1972; Thornhill et al 2012d). Of the species studied to date, only the pollen of C. guazumifolia (Cambess.)…”

Pollen morphology: a source of information for taxonomic studies within Campomanesia (Myrtaceae)

Campomanesia is a well-delimited Neotropical genus of Myrtaceae, but some of its species have a poorly understood circumscription. Pollen morphology can provide characters to clarify the relationships among such taxa. Here, we analyze the pollen grains of 16 species of Campomanesia using light and scanning electron microscopy. Heat map and multivariate regression tree analyses were performed aiming to detect differences among species based on pollen morphology. Pollen grains of the studied taxa are isopolar monads that are oblate or, less often, suboblate, 3(4)-colporate, syncolporate or parasyncolporate, with a triangular or quandrangular amb. The exine ornamentation varies among rugulate-granulate, granulate, rugulate and rugulate-espiculate. Fastigium is present in 14 species, and a costa is present in three species. The heat map and regression tree analyses based on 16 character states of pollen morphology were able to distinguish all species of Campomanesia studied here. Some species differ from all the other species, such as Campomanesia guaviroba due to its exclusively rugulate exine. Amb, shape and exine ornamentation were distinctive characters, as previously reported for other genera of Myrtaceae. However, the presence of fastigium also proved to be an informative pollen character for species distinction in Campomanesia. Based on the sample of this study, we can state that Campomanesia is a eurypalynous genus within Myrtaceae.
