    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.

    ABSTRACT Cuphea section Trispermum, one of the 13 sections of the genus, predominantly composed of Brazilian species, underwent a new circumscription after morphological and molecular studies. The pollen morphology of classic representatives of the section and related taxa transferred to this section was investigated, based on light microscopy and scanning electron microscopy, to support the taxonomy and the new section circumscription. The analyzed species present pollen that is small to medium in size, isopolar, oblate, triangular to ovate-triangular, tricolporate, and syncolpate, with prominent pores and psilate exine, thickened between the pores in the mesocolpium. The results of this study confirm the palynological homogeneity of C. sect. Trispermum, and of the taxa transferred from other sections, which are unified by exine thickening in the region between the pores. These characteristics corroborate the monophyly of the section, according to molecular phylogenetic studies.

    Informa UK Limited
    ABSTRACT Nineteen Neotropical species of the genus Dioscorea L. were subjected to palynological analysis with the objectives of increasing palynological knowledge and identifying characteristics with taxonomic and phylogenetic value. More specifically, the aim was to identify characters that distinguish species and help to resolve relationships among New World clades (i.e. clades NW I, NW II and NW III). Botanical material was obtained from exsiccates deposited in various herbaria. Pollen grains were treated by lactic acetolysis, measured, described, photomicrographed and submitted to statistical analysis. Non-acetolyzed pollen grains were deposited on carbon tape for scanning electron microscopy analysis. The results separate species of Dioscorea into six pollen types based on sexine ornamentation: reticulate, perforate, microreticulate, vermiculate, rugulate and spiculate. The pollen grains of species of Dioscorea are characterized by having monosulcate and disulcate apertures, sometimes in the same specimen (e.g. D. anomala, D. campestris and D. glandulosa). Traditionally accepted taxonomic sections of Dioscorea were not corroborated. Reassessment of established subgenera awaits a better understanding and recognition of phylogenetic lineages.

    Passiflora subgenus Astrophea is one of the five currently recognized subgenera of Passiflora. It is distributed throughout the neotropics, mainly in the Amazon rainforest. We present a taxonomic revision of species of Passiflora subgenus Astrophea occurring in Brazil, based on vegetative, floral and pollen morphology. A total of 31 species and 2 varieties were recognized and classified into four sections and two series. Four species were placed in section Capreolata, 2 species in section Leptopoda, 17 species and 2 varieties in section Pseudoastrophea and 8 species in section Botryastrophea, of which 4 were included in series Botryastrophea and 4 in series Carneae. Astrophea individuals can be identified by their variable habit, entire leaf-blades, two glands at the apex of the petiole or at the base of the leaf blade and white flowers with yellow corona and pink to purplish or red to orange hypanthium. We discuss the rediscovery of P. elliptica after 71 years and present new records of P. chlorina from Minas Gerais, additional information on the little-known P. phaeocaula, P. sclerophylla and P. mansoi var. glabra. Identification keys, complete descriptions, geographical distribution maps, etymology, taxonomic comments and illustrations are presented.

    Informa UK Limited
    Abstract Passiflora subgenus Passiflora possesses about 236 species divided into six supersections, among which Stipulata with Granadillastrum is one of its sections. The objective of the present study was to analyse the pollen morphology of 19 species subordinate to the section Granadillastrum and to identify attributes important for the taxonomy of the group. Pollen grains were acetolysed, measured, described and illustrated under light and scanning electron microscopy. Two pollen types differing in polarity were found in the section: Pollen Type I with apolar pollen grains and Pollen Type II with isopolar pollen grains. Type I included large, colpate pollen grains (varying from six to nine colpi), while Type II included large, 6-syncolpate or 3-colpate pollens. All of the studied species had a reticulate exine, sinuous muri, continuous with or without perforations, and ornamented lumina. Hierarchical cluster analysis and principal component analysis (PCA) were used to interpret the formation of the principal pollen groups based on morphology. Two of the analysed species of section (Passiflora imbeana and P. setulosa) are at risk of extinction. The present study is extremely important for characterising pollen morphology such that taxa can be delimited and knowledge acquired for conservation purposes. Five of the studied species had their pollen characterised for the first time, which will be useful to future taxonomic and phylogenetic analyses. This species have pollen characters, such as the number and type of apertures that are important for delimiting some species, while ornamentation in general is similar among taxa and characterises the section.
