“…T h e a b s e n c e a n d l o w r i c h n e s s o f Orchidaceae and Bromeliaceae families in inselbergs, respectively, may be related to the dry climate of the studied area and its surroundings. The few studies carried out in inselbergs in Ceará also have similar results, suggesting that these families are richer in more humid climates (Araújo et al 2008;Paulino et al 2018;Pereira et al 2018) than in the Caatinga domain.…”

The Seasonally Dry Tropical Forests and Woodlands biome (SDTFW) has its largest nucleus in the Caatinga domain. We characterized the flora and physiognomy of the vegetation in the Pedra da Andorinha Wildlife Refuge (RPA), in Ceará, Brazil. Plant collections were made between March/2015 and May/2021, applying usual botanical methods. All material was deposited in HUVA herbarium. The phytosociological studies covered five 50 m x 50 m plots established (1.25 ha) in which all individuals with diameters at soil level ³ 3 cm were inventoried. We identified 266 vascular plants species distributed among 185 genera and 67 families, including one fern (Marsilea deflexa - Marsileaceae). Fabaceae had the greatest species richness (38 spp.), while Ipomoea was the richest genus (9 spp.). 43.6% of all plant species were herbaceous, with a predominance of therophytes (57.5% of all herbaceous plants). The phytosociological study sampled 1,988 individuals distributed among 24 species of 13 families. The species with the greatest important value were Cordia oncocalyx (Boraginaceae) and Croton blanchetianus (Euphorbiaceae). We classify the local physiognomy as typical caatinga sensu stricto vegetation and rocky vegetation on inselbergs and outcrops. We highlight the richness of herbaceous plants in the local community, which surpass the richness of the woody component.

“…França, Melo, & Santos, 1997;Esgario et al, 2009;Couto et al, 2017;Pena & Alves-Araújo, 2017). Fabaceae, for example, has a species richness in the PAC similar to that found on inselbergs in the Caatinga Domain (Araújo, Oliveira, & Lima-Verde, 2008;Tölke, Silva, Pereira, & Melo, 2011;Paulino, Silveira, & Gomes, 2018). This finding contradicts the results of other floristic surveys conducted in Espírito Santo, in which the most-represented families were Orchidaceae, Bromeliaceae, Asteraceae, Melastomataceae, Cyperaceae, Poaceae, Polypodiaceae, Cactaceae and Araceae (Esgario et al, 2009;Couto et al, 2017).…”

Inselbergs are granitic or gneissic rocky outcrops prevalent in the landscape of southeastern Brazil. These ecosystems represent islands of isolated habitats that harbor a peculiar flora with high richness and endemism. The present study lists the species of vascular plants occurring in the Pedra da Andorinha Complex, located in the municipality of Jerônimo Monteiro/Cachoeiro de Itapemirim, southern Espírito Santo state, aiming to generate subsidies for the creation of a protected area. The survey was performed between July 2017 and October 2018, resulting in a record of 121 species, 96 genera, and 40 families. Bromeliaceae (17), Orchidaceae (12) and Fabaceae (10) were the richest families. The phytophysiognomy of exposed rock vegetation comprises a greater number of species (79 species) compared to the woody rupicolous communities (42). Eighteen of the collected species are threatened by extinction; a new species was discovered; and five were described based on materials previously collected in the studied location — Alcantarea patriae, Anthurium martinellii, Coleocephalocereus uebelmanniorum, Stigmatodon attenuatoides and Pitcairnia azouryi, the first four being endemic to the region. We also found Tabebuia reticulata, a rare species among Brazilian flora. Our results highlight the biological importance of the Pedra das Andorinhas Complex and reinforce the need to create a protected area to preserve biodiversity and the regional natural heritage.

“…Especificamente no nordeste brasileiro, nos últimos anos observou-se um crescente número de estudos direcionados ao conhecimento da flora dos afloramentos rochosos (Silva, 2016), entre os quais se destacam os desenvolvidos na Bahia (França et al, 1997(França et al, , 2005(França et al, , 2006Moraes et al, 2009); no Ceará (Araújo et al, 2008;Paulino et al, 2018;Pereira et al, 2018); na Paraíba (Almeida et al, 2008;Porto et al, 2008;Tölke et al, 2011;Sales-Rodrigues et al, 2014;Silva et al, 2015;Lopes-Silva et al, 2019); em Pernambuco (Gomes e Alves, 2010;Pessoa e Alves, 2014). Porém, Silva (2016) ressaltou que o conhecimento sobre a flora dos afloramentos rochosos é ainda insuficiente, especialmente, em relação à conservação.…”

Os afloramentos rochosos ocorrem principalmente em regiões de climas áridos e são reconhecidos por apresentarem uma flora altamente especializada, com altos níveis de diversidade e endemismo. O objetivo do estudo foi realizar um levantamento florístico em ambientes de afloramentos rochosos visando registrar a diversidade local e contribuir para a ampliação do conhecimento da flora brasileira. O estudo foi desenvolvido nos afloramentos rochosos conhecidos popularmente como Pedra Talhada, Três Lagoas e dos Bois, todos localizados na Reserva Biológica de Pedra Talhada no município de Quebrangulo, Alagoas. Coletas mensais foram realizadas durante dois anos (2013 - 2014). Para a identificação dos táxons foram consultadas bibliografias especializadas, guias e sítios de imagens, além de especialistas. Na Rebio de Pedra Talhada foram identificadas 160 espécies de angiospermas pertencentes a 132 gêneros e 60 famílias. Nas três áreas estudadas predomina o estrato herbáceo-arbustivo (77,3%), no entanto, diferem quanto a riqueza e composição florística. As famílias com maior representatividade foram Orchidaceae (13 spp.), Rubiaceae (12 spp.) e Asteraceae (11 spp.). São indicadas 15 novas ocorrências para Alagoas; cinco para o domínio Mata Atlântica e um novo registro para a região Nordeste do Brasil. Floristic Diversity of the Rocky Outcrops in the Pedra Talhada Biological Reserve, Quebrangulo, Alagoas ABSTRACTThe rocky outcrops occur mainly in regions with arid climates and are recognized for having a highly specialized flora, with high levels of diversity and endemism. The aim of the study was to carry out a floristic survey in rocky outcrop environments in order to register the local diversity and contribute to the expansion of knowledge of Brazilian flora. The study was carried out on rocky outcrops popularly known as Pedra Talhada, Três Lagoas and dos Bois, all located in the Pedra Talhada Biological Reserve in the municipality of Quebrangulo, Alagoas. Monthly collections were carried out for two years (2013 - 2014). For the taxa identification, specialized bibliographies, guides and image sites were consulted, in addition to specialists. In Rebio de Pedra Talhada, 160 species of angiosperms belonging to 132 genera and 60 families were identified. In the three areas studied, the herbaceous-shrub stratum predominates (77.3%), however, they differ in terms of richness and floristic composition. The most representative families were Orchidaceae (13 spp.), Rubiaceae (12 spp.) and Asteraceae (11 spp.). 15 new occurrences are indicated for Alagoas; five for the Atlantic Forest domain and a new record for the Northeast region of Brazil.Keywords: Angiosperms, Atlantic Forest, new occurrences, Northeast of Brazil.
