ABSTRACT The family Vitaceae has a wide distribution, occurring in temperate, subtropical, and tropical climates. Vine members of the family thrive in different types of vegetation. Currently, the family includes five recognized tribes: Ampelopsideae, Cisseae, Cayratieae, Parthenocisseae, and Viteae. This study describes the pollen morphology of representatives of Ampelopsideae, Cayratieae, and Parthenocisseae. The other tribes are not described because they have been the subject of previous studies. The aim was to assess the relationships among the five tribes using multivariate analysis and to reconstruct the evolution of pollen characters using existing phylogenetic hypotheses. Specimens representing the three tribes were obtained from herbaria, treated by the acetolysis method, measured, photographed, and described using light and scanning electron microscopy. Results showed that pollen grains are medium (25–50 µm) in size, isopolar, tricolporate, and subprolate to prolate. Ornamentation varies between species. Multivariate analysis was based on quantitative characters, of which pollen diameters, apocolpium side, and polar area index were the most significant. Tracing of pollen characters showed that size, shape, and ornamentation are an evolutionary trend within the family. This investigation expands the palynological knowledge on representatives of Vitaceae tribes, contributing to future palynotaxonomic and evolutionary studies.

Abstract The tribe Viteae comprises about 200 species and is represented by the genera Vitis and Ampelocissus. Vitis is the most studied genus within the grape family (Vitaceae) because of the global economic importance of its fruits and derived products. This study examined the palynology of Ampelocissus and Vitis species belonging to the tribe Viteae to identify pollen characters that may contribute to the taxonomic and morphological characterisation of Ampelocissus. Pollen specimens were obtained from herbaria, treated by the acetolysis method, measured, photographed, and described using light and scanning electron microscopy. In the analysed species, pollen grains were isopolar or heteropolar, medium-sized, tricolporate, oblate spheroidal to subprolate. Ornamentation patterns differed among species, with examples of bireticulate, microreticulate, perforate, reticulate, and rugulate sexine. These characters were used for the development of a pollen key to the genera. Principal component analysis revealed that quantitative pollen characters were the most important for group discrimination. This study contributes to the palynological knowledge of some undescribed species and provides novel palynotaxonomic information on the family Vitaceae.

ABSTRACT The Blechnaceae is a family of leptosporangiate ferns with a wide geographical distribution. Recent phylogenies revealed several lineages within the family, culminating in a classification system comprising 25 recognized genera grouped into three subfamilies. Spore surface morphology has major importance in the taxonomy of the group, but there is limited information on the relevance of other palynological characters. This study aimed to examine whether spore morphology aids in distinguishing genera of Blechnaceae according to the current phylogenetic classification. Spores from 28 species distributed in 12 genera of the subfamilies Blechnoideae, Stenochlaenoideae, and Woodwardioideae were examined. Specimens were acetolyzed, measured, described, and illustrated using light and scanning electron microscopy. The analyzed spores were medium to large in size, with a monolete scar of varied size, straight, and without margo. The perine was three-layered, except in the subfamily Stenochlaenoideae, which showed a single-layered perine. Blechnoideae was the most palynologically diverse subfamily. Woodwardioideae and Stenochlaenoideae spore characters had high diagnostic value for identification at the genus level. Austroblechnum and Blechnum showed high similarity; no single spore character could be used to discriminate between species of these genera. Blechnum anthracinum was the only species within its genus to exhibit cristate spores, with filaments and perforations. Morphometric analysis did not prove to be a useful tool for differentiating subfamilies or genera, possibly because of the influence of polyploid individuals. This investigation revealed unique spore characters for some genera and provided morphological descriptions that allow identification at the species level, contributing to the taxonomic study of Blechnaceae.

ABSTRACT Lippia is the second largest genus in the family Verbenaceae, comprising about 100 species widely distributed in the Neotropics and some representatives in Africa. The genus is considered poorly delimited taxonomically because many species can only be distinguished by minor morphological differences, resulting in a large number of described taxa. This study aimed to examine and describe the pollen characters of Lippia sect. Rhodolippia and identify important pollen attributes for the delimitation of species occurring in Brazil. Multivariate analysis was used to investigate similarities between species and find diagnostic characters for taxonomic identification. Pollen grains of 16 species were acetolyzed, measured, described, illustrated using a light microscope (LM) and submitted to statistical treatments. For a more detailed examination of pollen surfaces and apertures, non-acetolyzed pollen grains were observed and micrographed by scanning electron microscopy (SEM). The results showed that species belonging to the section Rhodolippia have pollen grains that are prolate spheroidal or oblate spheroidal, 3-colporate (3-4-colporate in L. felippei) or 3-colpororate, mesoaperture present or absent, endoaperture lalongate, with ends bifurcated, tapered, rounded, H-shaped or truncated. The exine ornamentation is psilate-perforate in most species. Principal component analysis and hierarchical clustering identified two groups: 3-colporate and 3-colpororate pollen grains. Palynological analysis evidenced the eurypollinic character of the genus and resulted in the first description of mesoaperture and the type of ends of the endoaperture. These findings can provide taxonomic and phylogenetic support for future studies on Lippia.

ABSTRACT The family Passifloraceae sensu stricto occurs mainly in the Neotropical region. Four genera are represented in the American flora, Ancistrothyrsus Harms, Dilkea Mast. (restricted to the Amazon rainforest), Mitostemma Mast., and Passiflora L. The largest and most studied genus is Passiflora. The three other genera are considerably smaller; Ancistrothyrsus contains two species, Dilkea twelve, and Mitostemma three. This study aimed to perform a palynological characterization of six species belonging to the genera Ancistrothyrsus, Dilkea, and Mitostemma: Ancistrothyrsus tessmannii Harms, Dilkea johannesii Barb. Rodr., Dilkea retusa Mast., Mitostemma brevifilis Gontsch., Mitostemma glaziovii Mast., and Mitostemma jenmanii Mast. Pollen specimens were acetolyzed, measured, described, and photographed with light and scanning electron microscopes. Pollen grains are medium- or large-sized, prolate-spheroidal, 3-colporate in Ancistrothyrsus and Mitostemma and (3)4(5)-colporate in Dilkea. The sexine is thick, reticulate, muri sinuous or straight, simplicolumellate, with two nexine layers in some species. Pollen morphology is an important source of taxonomic information that allows distinguishing and identifying species of the genera Ancistrothyrsus, Dilkea, and Mitostemma, making it possible to draw comparisons with the genus Passiflora. The descriptions presented in this study contributes to the knowledge of the pollen flora of Passifloraceae.
