“…Typical spikelets of Poales lack a terminal flower (Eiten, 1976;Vrijdaghs et al, 2010;Kellogg, 2015), unless the problematic reproductive structures of Cyperaceae-Mapanioideae are interpreted as partial inflorescences (Richards et al, 2006;Vrijdaghs et al, 2006;Prychid and Bruhl, 2013;Monteiro et al, 2016). In the biotically pollinated families Bromeliaceae, Eriocaulaceae, and Xyridaceae, the inflorescences are racemose and lack a terminal flower (Stützel, 1982;De Sousa et al, 2008;Remizowa et al, 2012;Nogueira et al, 2017Nogueira et al, , 2021. In Mayacaceae, the flowers are solitary and axillary (Oriani and Scatena, 2019).…”

The family Rapateaceae represents an early-divergent lineage of Poales with biotically pollinated showy flowers. We investigate developmental morphology and anatomy in all three subfamilies and five tribes of Rapateaceae to distinguish between contrasting hypotheses on spikelet morphology and to address questions on the presence of nectaries and gynoecium structure. We support an interpretation of the partial inflorescence (commonly termed spikelet), as a uniaxial system composed of a terminal flower and numerous empty phyllomes. A terminal flower in an inflorescence unit is an autapomorphic feature of Rapateaceae. The gynoecium consists of synascidiate, symplicate, and usually asymplicate zones, with gynoecium formation encompassing congenital and often also postgenital fusions between carpels. Species of Rapateaceae differ in the relative lengths of the gynoecial zones, the presence or absence of postgenital fusion between the carpels and placentation in the ascidiate or plicate carpel zones. In contrast with previous reports, septal nectaries are lacking in all species. The bird-pollinated tribe Schoenocephalieae is characterized by congenital syncarpy; it displays an unusual type of gynoecial (non-septal) nectary represented by a secretory epidermis at the gynoecium base.

“…A microtomografia de raios X, também chamada como µCT, é caracterizada por permitir uma resolução espacial próxima a 1 µm (LANDIS; KEANE, 2010), levando a novas possibilidades de investigações científicas de tecidos com elevado grau de detalhes microscópicos, como amostras vegetais (NOGUEIRA et al, 2017). O destaque principal desta técnica é sua característica não invasiva, ou seja, que permite a visualização de qualquer região interna da amostra sem a necessidade de cortes físicos, processos de emblocamento, ou a consequente degradação da amostra.…”

“…A µCT é uma ferramenta poderosa para análises quali-e quantitativas de materiais naturais e, especialmente, em plantas, permitindo obter imagens e dados volumétricos de órgãos, tecidos e células (NOGUEIRA et al, 2017). Para tal é possível a segmentação de cada região de interesse para uma análise isolada.…”

“…Peng et al [43] used X-ray microtomography (lCT) in a bamboo sample (Pleioblastus gozadakensis) revealing a partial 3D view of the node, yet authors did not perform a segmentation procedure, thus impairing the actual visualization and the correct interpretation of the morphology of the vascular bundles. In addition to a better visual analysis of a region of interest (ROI) of plants [44,45], segmentation of lCT stack images allows such models to be exported to 3D file extensions, e.g., for application in 3D printing [15,46,47] and finite element analysis (FEA) [16,48]. Notably, Petit et al [49] present a broad review and highlight the main applications of lCT and FEA for the study of cellular solids.…”
