“…More than 60 taxa have been described based on specimens collected in the Carajás region over the last 50 years (Giulietti et al under review) and discovery of species new to science continues to the present day, e.g. Anemopaegma carajasensis [54], Peperomia albopilosa , P . pseudoserratirhachis [55].…”

In order to establish effective conservation strategy, drivers of local and regional patterns of biodiversity need to be understood. The composition of local biodiversity is dependent on a number of factors including evolution and redistribution of lineages through dispersal and environmental heterogeneity. Brazilian canga is characterised by a ferrugineous substrate, found both in the Iron Quadrangle of Minas Gerais and in the Carajás mountains in Amazonia. Canga is one of several specialised habitat types comprising Brazilian campo rupestre , a montane vegetation found within or adjacent to several major Brazilian bioregions, including the Atlantic Forest and Amazonia, with exceptionally high levels of diversity and endemism arising from both history of dispersal and environmental variation. In order to inform biodiversity conservation for canga , and more broadly for campo rupestre , we performed floristic and phylogenetic analyses investigating affinities between 28 sites on different substrates ( canga and quartzite) and geographic locations (Carajás, Pará [Amazonia]; Cadeia do Espinhaço, Minas Gerais; Chapada Diamantina, Bahia). Through analysis of 11204 occurrences of 4705 species of angiosperms, we found that Amazonian Carajás canga plant communities formed a cohesive group, distinct from species assemblages found in Eastern Brazil (Minas Gerais, Bahia), either on canga or quartzite. The phylogenetic megatree of species across all sites investigated shows associations between certain clades and Amazonian canga , with few shared species between the Amazonian Carajás and Eastern Brazil sites, while the floristic comparison shows high levels of heterogeneity between sites. The need for reserves for Amazonian Carajás canga has been recognized and addressed by the creation of a national park. However, current sampling does not provide sufficient reassurance that the canga areas now benefitting from full legal protection adequately represent the regional canga flora.

“…Preserved specimens were deposited at the HDELTA herbarium (Herbarium Delta do Parnaíba, Universidade Federal do Delta do Parnaíba, Parnaíba, Piauí). Identifications were obtained from specialized bibliography including Gentry (1980), Lohmann & Taylor (2014) and Lohmann et al (2018), and morphological comparison was made with herbarium specimens and images deposited at the TEPB herbarium (Herbarium Graziela Barroso, Universidade Federal do Piauí, Teresina, Piauí), the Virtual Herbarium of the Flora and Fungi-REFLORA (BR), and the online herbarium of the New York Botanical Garden (NY). Morphological descriptions were made following the terminology of Hickey (1973), Rizzini et al (1997), Lohmann & Pirani (1996, 1998, 2003, Silva-Castro & Queiroz (2003), Rodrigues (2012), Oliveira (2013), , Machado & Romero (2014), and Silva et al (2018).…”

The present study is a taxonomic treatment of Bignoniaceae from the four municipalities of the coastal region of Piauí state (Cajueiro da Praia, Ilha Grande, Luís Correia, Parnaíba) in Northeast Brazil, based on morphological study of newly collected and existing herbarium material. The study recorded 26 species in 12 genera: Adenocalymma, Anemopaegma, Bignonia, Cuspidaria, Dolichandra, Fridericia, Handroanthus, Lundia, Neojobertia, Pleonotoma, Stizophyllum and Tanaecium. Apart from Handroanthus impetiginosus, which belongs to tribe Tecomeae, all other species belong to tribe Bignonieae. Five species (Adenocalymma apparicianum, A. pedunculatum, Anemopaegma heringeri, A. prostratum, Dolichandra hispida) are new records for the state of Piauí, 15 species are endemic to Brazil, and one has “Vulnerable” conservation status. The results emphasize the importance of taxonomic studies for knowledge of biodiversity and threats to native species, and reinforce the importance of conserving the region’s flora. Species descriptions, illustrations, identification keys and information on geographic distribution and habitat are provided.

“…Al Gentry's legacy of Bignoniaceae has been carried forward, largely thanks to the contributions of Lúcia Lohmann's group (Universidade de São Paulo, Brazil) in the tribe Bignonieae. Continued descriptions of new species (e.g., Firetti-Leggieri et al, 2015;Frazão & Lohmann, 2018), range extensions (e.g., Brito et al, 2018), checklists (e.g., Lohmann & Ulloa Ulloa, 2006), floristic treatments (e.g., Lohmann et al, 2018;Costa et al, 2019), synopses (e.g., Lohmann & Taylor, 2014;Fonseca & Lohmann, 2019), and monographs (e.g., Medeiros & Lohmann, 2015;Francisco & Lohmann, 2018) are conducted in parallel with studies on the phylogenetics (e.g., Lohmann, 2006; Kaehler et al, 2019), biogeography (e.g., Lohmann et al, 2013;Thode et al, 2019), and evolution of traits associated with the climbing habit (e.g., Pace et al, 2011Pace et al, , 2015Sousa-Baena et al, 2014), insect-plant interactions (Nogueira et al, 2012(Nogueira et al, , 2015, and pollination systems (e.g., Alcantara & Lohmann, 2010, 2011, among others. Across these diverse works on Bignoniaceae, an in-depth, organismally focused understanding of the ecology and evolution of the largest clade of Neotropical lianas has emerged.…”

The Neotropics are the most species-rich area of the planet. Understanding the origin and maintenance of this diversity is an important goal of ecology and evolutionary biology. Success in this endeavor relies heavily on the past work of taxonomists who have collected specimens and produced the floras and monographs that constitute the foundation for the study of plant diversity. To illustrate this, we visualize collecting efforts through time and identify the importance of past taxonomic and collection efforts in generating the bulk of specimen data that broad-scale analyses rely on today. To demonstrate the importance of taxonomy for the study of Neotropical biodiversity, we showcase selected plant groups in which in-depth taxonomic understanding has facilitated exciting evolutionary and ecological research and highlight the teams of scientists who have built on the legacy of Alwyn Gentry, one of the most prolific taxonomists of the late 20th century. We also discuss challenges faced by taxonomists, including perceived subjectivity, difficulty in measuring impact, and the need to become more interdisciplinary. We end with potential solutions going forward, including integration of taxonomists in interdisciplinary research, advocacy for continued collection efforts, increased funding for alpha taxonomic research that is performed with increasingly replicable methodology, and explicit decolonization efforts to increase inclusivity and equity in the field of taxonomy. Acknowledging the central role of taxonomy and taxonomists is essential to accurately and completely describe Neotropical biodiversity patterns in an age of unprecedented extinction risk and conservation need.
