“…bicolor , and C . inermis ) previously adopted for Brazilian collections has led to the overly broad and erroneous application of this name to specimens of both T. bicolor and T. inermis (Costa‐e‐Silva, ; Costa‐e‐Silva & al., ; Akemi‐Borges & Pirani, ). This broad circumscription of T. rosea is not supported by our results, and the distinction of these three species by Soares Neto & al.…”

“…In 1952, he divided this section into 8 series and recognized 24 species and 22 subspecies, based on the size of flowers, color of the petals, length of the stamens, gynophore and fruits, characteristics of the seeds, and geographic distribution (Table ). Although no definitive circumscription of the section was formally presented, subsequent studies informally adopted Iltis's proposal (e.g., Jacobs, and Costa‐e‐Silva, , for local treatments; Iltis, and Iltis & Zapata, , when describing Cleome afrospina Iltis and C . torticarpa Iltis & T.Ruíz, respectively).…”

The family Cleomaceae is represented in the Neotropics by nine native lineages, with some of them currently recognized as distinct genera and others in need of clear delimitation. We present here a new phylogenetic hypothesis for the New World Cleomaceae with a more comprehensive sampling, including samples of 62 species with emphasis on Tarenaya and based on nrDNA ITS and cpDNA matK and ndhF. Six clades are supported: (1) a new clade comprising Cleome tenuis and Physostemon humilis; and five other previously identified clades: (2) the Dactylaena clade, including the monophyletic Dactylaena and the paraphyletic Physostemon and Mitostylis; (3) the Andean clade, comprising Andinocleome and Podandrogyne; (4) the Melidiscus clade; (5) the Cleoserrata clade, and (6) the Tarenaya clade; the last three corresponding to genera with the same name. The lineage comprising C. tenuis and P. humilis is strongly supported by morphological and molecular datasets, and a new genus, named Iltisiella, comprising these species is proposed here. Tarenaya is clearly demonstrated to be a monophyletic genus, corroborating previous analyses. We identify four subclades in its topology, and the relationships among the species in each subclade revealed to be moderately to strongly resolved. Furthermore, we conducted a historical biogeographical analysis of the New World Cleomaceae on time-calibrated trees, and our results suggest an Oligocene origin at least 35.02 Mya with a MRCA distributed in Mesoamerica and the Northern Andes. For Tarenaya, our results suggest a Miocene origin at least 17 Mya, with the most recent common ancestor in the Chacoan and Atlantic Forest geographic areas.

Anatomical, Morphophysiological and Molecular Characterization of Brazilian Species of Cleomaceae

Cleomaceae is one of the 17 families of the order Brassicales, which comprises 26 genera and about 270 species. This cosmopolitan family has a great morphological and physiological diversity and due it is a sister group of Brassicaceae, to which the model plant Arabidopsis is inserted, it has been the subject of studies in several areas. However, despite being a promising family, there are few species characterized, so far only 15 have been physiologically characterized. Thus, this work aimed to characterize species of Cleomaceae occurring in Brazil. In this sense, visits to herbariums and collections were carried out in various regions in order to better understand the identity, ecology and distribution of each species. Thus, 22 species were sampled. Morphological and molecular characterization, based on five markers, showed that the Tarenaya series are monophyletic (Chapter 1) and that T. siliculifera is morphologically distinct from the species of the genus, so the recognition of a new monotype genus has been proposed (Chapter 2). In addition, we characterized the 22 species in terms of genome size, molecular phylogeny, anatomical, biochemical, and physiological characteristics (Chapter 3). In addition to determining the photosynthetic parameters, biochemical analyzes were performed on the leaves throughout the day (Chapter 4). Interestingly, the C 3 species groups exhibit clear variation in anatomical, physiological and biochemical parameters, suggesting a large natural variation among these species. Furthermore, unrecognized variation in leaf structure and physiology within the species studied indicates varying degrees of development of the C 3 -C 4 photosynthetic mechanism. Furthermore, the Brazilian Cleomaceae accessions characterized here exhibit a high genetic diversity and may represent different stages of development of the photosynthetic mechanism from C 3 to C 4 . Regarding the characterization of the sexual type of each flower (Chapter 5), the 20 morphospecies formed three four groups of sexual expression: andromonoicia, hermaphrodites, and polygamous. In addition, dichogamy and distyly were also observed, however, the species studied are self-compatible. Finally, a compilation of all available information about Cleomaceae is carried out in Chapter 6 in order to identify the characteristics of each group and indicate the advances in each area with the family.

Pollen morphology and evolutionary history of Sapindales

et al. 2021

In Brazil, Sapindales is represented by six families Anacardiaceae, Burseraceae, Meliaceae, Rutaceae, Sapindaceae, and Simaroubaceae. Palynological studies on its members are varied, including few detailed descriptions as well as palynotaxonomic analyses or brief diagnoses in floras or ecological, paleopalynological, or melissopalynological investigations. This study aimed to compile the main pollen characters of Sapindales families occurring in Brazil through a thorough review of the literature including national or foreign taxa and to present new information on the palynology of representatives of the families. Acetolyzed pollen grains from representatives of the six families were also analyzed, measured, and illustrated under light microscope. Unacetolyzed pollen grains were analyzed using scanning electron microscopy. An evolutionary approach to pollen morphology in Sapindales was carried out by mapping and reconstructing the ancestral states of the pollen grains attributes on the existing phylogenetic proposal. Phylogenetic trees were generated by parsimony analysis and used to reconstruct the evolutionary history of each character state of the analyzed taxa. This study represents a first attempt to establish the phylogeny of the order Sapindales using pollen data. Future palynological studies should focus on species not included in the current phylogenetic tree as well as phylogenetic relationships within the nine Sapindales families.
