The aim of this study was to conduct a floristic inventory and update the geographical distribution of Talinaceae species in Ceará state, in the Northeast Region of Brazil. The study was based on a comparative analysis of morphological characters of specimens deposited in the EAC, ESA, HCDAL, HUEFS, HUVA, HVASF, MOSS and RB herbaria, specialized literature, photos of type collections, and field expeditions conducted between March 2015 and April 2022. For the state, Talinum fruticosum and T. paniculatum have been recorded, which prefer drier vegetations, such as Stepic Savanna (Caatinga and Carrasco) and Semideciduous Seasonal Forest (Mata Seca), but also grow in areas that are more humid. The species occur in eight conservation units in Ceará: Dunas da Lagoinha and Serra de Meruoca Environmental Protection Areas, Aiuaba Ecological Station, Sobral National Forest, Ubajara National Park, Pedra da Andorinha Wildlife Refuge, Serra das Almas and Fazenda Trussú Private Natural Heritage Reserves. An identification key, descriptions, photographs, and comments about the geographical distribution, taxonomic relationships, and phenology are provided for the species.

The in orescences of Portulacaceae have traditionally been considered capitula and their morphology and architecture have not been studied in detail. The purpose of this study was to expand the knowledge on the in orescences within this family, comparing members of distinct lineages of Portulaca occurring in Brazil, to understand some systematic and evolutionary patterns within this group. Morphological characteristics of the in orescences were analyzed using a light stereomicroscope, and for anatomical studies, we made transversal and longitudinal sections along the entire in orescence, including involucral bracts, analyzing them using an optical microscope. We con rmed that observed in orescences are determinate, composed of a rst-order dichasium, with second-order helicoidal branches forming a cephalioid structure. The involucral leaves differed from adjacent bracts, which did not display a constriction at the base, as commonly observed in leaves. Thus, we conclude that the congested in orescence of Portulaca is not a capitulum, but a cephalioid with different degrees of branch reduction within the genus. The Pilosa clade displayed the most congested cephalioid compared to members of the other analyzed clades. We showed present to show a new interpretation of the congested in orescences in Portulacaand reinforce the need to analyze solitary in orescences to understand the importance of these data to systematics, evolution, and pollinator-plant interactions within Portulacaceae.

Quelites—Agrobiodiversity beyond our crops

The monoculture of a handful of energy-dense crops that dominates contemporary agriculture has resulted in an erosion of agrobiodiversity, environmental issues, agroecosystem dependency on off-farm inputs, and diets with poor diversity in nutrients and flavors. However, diversified agriculture persists in communities characterized by subsistence farming, many of them Indigenous. Although movements across Latin America aim to rescue agrobiodiversity, they are widely limited to cropping system diversification, including practices such as crop rotations, intercropping, and cover crops. The agrobiodiversity of plants associated with crops, often labeled as weeds, is commonly not considered in this context. Yet edible weeds are the essential components of traditional food systems where they increase the functional diversity of agroecosystems and contribute to human nutrition. In Mexico, the term “quelite” describes noncultivated but edible plants growing on a crop field. Across the American continent, there are nutritious quelites that are commonly perceived as “weeds.” In this article, we discuss the concept of quelites, their origin in traditional Mexican agriculture, their significance for agroecosystem diversification, and their potential for the future. We demonstrate, with 12 examples, that quelites have always been part of agroecosystems across the Americas. We aim to spread the concept of quelites beyond traditional farming in Mexico to promote the use of these promising plants. We conclude the article with suggestions for strategies to achieve this goal.
