 Leguminosae Juss. from Nascentes do Rio Parnaíba National Park, BrazilianCerrado

Abstract A synopsis of the Leguminosae from the Park Nacional das Nascentes do Rio Parnaíba (PNNRP), located in the northern and northeastern regions of Brazil, is presented herein. A total of 68 species and 2 infraspecific taxa belonging to 29 genera and four subfamilies (i.e., Caesalpinioideae, Papilionoideae, Detarioideae, and Cercidoideae) were recorded. Of these, 14 species were considered new records for the northeastern or northern regions of Brazil, or for the states encompassing PNNRP. Genera with the highest number of species were Chamaecrista (15 spp.), Bauhinia (8 spp.), and Mimosa (6 spp.). Regarding plant physiognomies where the species were collected, Cerrado sensu stricto was predominant, followed by Cerradão and Veredas. Most of catalogued species had an unassessed conservation status, except for Bowdichia virgilioides, Chamaecrista coradinii, and Hymenaea parvifolia, which were classified as Near Threatened and Vulnerable, respectively. Treatment includes information on geographical distribution and taxonomic notes for species with an extended range.

Abstract

Advances in phylogenetic knowledge have brought about the need to combine the widely accepted principle of monophyly with morphological diagnosability in proposing new classifications. This is the case of the genus Chamaecrista (Leguminosae, Caesalpinioideae), where the traditional infrageneric classification has not been supported by the genus’s phylogenetic structure. In this study, we used a comprehensively sampled phylogeny to reassess the recently published infrageneric classification of Chamaecrista. We generated 471 sequences from three plastid and two nuclear DNA regions, including entirely new accessions from a fresh specimen of the morphologically puzzling Chamaecrista bucherae from the monospecific sect. Adenophyllum. By conducting ancestral character reconstruction analyses to trace the evolution of morphological traits, we aim to assess the congruence between traditional and alternative classifications of the sect. Baseophyllum. Our findings have unveiled three evolutionarily, geographically, and morphologically coherent lineages, which we reclassify as the three sections: Adenophyllum, Baseophyllum, and Otophyllum. This newly proposed infrageneric classification within Chamaecrista ensures nomenclatural stability and more practical identification, enhancing the challengeable taxonomy of this highly diverse genus.

Floral Nectaries in Leguminosae: Structure, Diversity, and Possible Evolution

 Floral Nectaries in Leguminosae: Structure, Diversity, and Possible Evolution

 Abstract Leguminosae, the third largest angiosperm family, is a taxon displaying the excep tional diversity of flowers and having great agricultural significance. Despite the broad range of reproductive strategies in this group, floral nectar is a key reward of legumes. The paper aims to summarize the available data on structure, ontog eny, regulation, and possible evolution of the leguminous floral nectaries. To date, detailed characterization of ultrastructure and mode of secretion is available only for a few representatives of the family whereas the majority remains understudied from this perspective. In most cases, regardless of flower symmetry, nectaries are localized between stamens and a carpel. The nectar is usually exuded from modified stomata although the exact mode of secretion by specialized parenchyma may differ between taxa. The leguminous floral nectaries often have certain features of mono symmetry with preferentially abaxial development. Nectaries were independently lost in several lineages, and equally recurrent is the emergence of substitutive, i.e. evolutionary innovative, nectar-producing structures. Floral nectaries possess a cer tain degree of evolutionary inertia, i.e. they remain stable even in lineages in which f lower morphology underwent significant changes compared with an ancestral plan, such as shifts in merism, symmetry, reduction or polymerization of organs and alike. Due to their evolutionary stability, floral nectaries are rarely used in the tax onomy of Leguminosae.
