“…The total number of species from MS may be underestimated, as indicated by three recently described species (Braun & Pereira 2008, 2009, Leme et al 2012, all of them suffering with habitat loss. Recently, for the first time, natural populations of D. excelsa were found in ironstone outcrops (Corumbá and Ladário cities, Pantanal region, MS) (Paggi et al 2015). This species was described based on a single individual from a private collection (Leme 1993), without describing the precise provenance.…”

“…The diversity of Bromeliaceae in Brazil is highest in humid areas of the Atlantic rainforest along eastern Brazil, with a decrease in species richness observed toward the drier inland territory (Reitz 1983, Versieux & Wendt 2006, 2007, Martinelli et al 2008. Nevertheless, drier areas may harbor endemic and xerophytic species, the systematics, taxonomy, and conservation of which have not yet received much attention (e.g., Miranda 2001, Braun & Pereira 2009, Leme et al 2012, Paggi et al 2015.…”

“…As a result of the collections that have become available recently, new Bromeliaceae taxa are being described or rediscovered from MS (e.g., Braun & Pereira 2008, 2009, Leme et al 2012, Versieux et al 2013, Paggi et al 2015, but the knowledge of this family in MS is still fragmentary and is aff ected by the paucity of collections available in herbaria. The aim of this study is to provide a preliminary checklist for that state, which may help future studies focused on the taxonomy and conservation of this family in central-western Brazil.…”

A checklist of 11 genera and 41 species of Bromeliaceae occurring in the state of Mato Grosso do Sul (MS) is presented. Of the total number of species, fi ve are endemic and belong to the genera Dyckia and Tillandsia. The subfamily Pitcairnioideae is the richest in number of genera and species, including taxa that are rare in Brazil (Deuterocohnia and Fosterella). Tillandsioideae is the richest subfamily in species number plus one infraspecifi c taxon; however, it is only represented by Tillandsia, and most species are widely distributed all over Brazil and/or nearby countries. Bromelioideae, a subfamily characteristic of the Atlantic rainforest is less represented. This checklist updates the number of species in Mato Grosso do Sul, when compared to the Offi cial Brazilian Plant Checklist.

RESUMO Tillandsia usneoides, conhecida como barba-de-velho, possui importância na medicina popular, com atividade antiviral, antioxidante, hipoglicêmica e antitumoral. Nesse contexto, o objetivo do trabalho foi realizar a caracterização anatômica foliar de T. usneoides, atrelado a testes histoquímicos visando auxiliar na identificação da espécie e subsidiar estudos taxonômicos e farmacológicos. O material vegetal foi coletado em uma área de restinga no norte do Espírito Santo. Para as análises anatômicas foram utilizadas técnicas usuais de anatomia vegetal. Para os testes histoquímicos, foram analisadas as seguintes substâncias: amido, lignina, lipídeos, compostos fenólicos e cristais. Em vista transversal, o limbo apresenta epiderme uniestratificada recoberta por cutícula e presença das células centrais das escamas epidérmicas. Subsequente, a hipoderme é caracterizada por células aclorofiladas, dispostas em uma única camada. O mesofilo é homogêneo, constituído por parênquima clorofiliano, cujas células possuem formato isodiamétrico. As fibras preenchem as extremidades dos feixes vasculares, os quais encontram-se dispersos na região central do mesofilo. Em vista frontal, as células da epiderme possuem parede celular ondulada, estômatos tetracíticos, geralmente recobertos pelas escamas, que são numerosas e distribuídas de forma aleatória ao longo da folha. Dentre os testes histoquímicos analisados, houve apenas reação positiva para lipídeos e os cristais do tipo ráfides possuem composição de oxalato de cálcio. Os caracteres distintivos de T. usneoides são folhas com formato circular, parede celular ondulada das células epidérmicas, estômatos tetracíticos e escamas com séries de quatro, oito e dezesseis células, sendo a ala assimétrica. PALAVRAS-CHAVE: Anatomia da folha, Testes Histoquímicos, Tillandsioideae. LEAF ANATOMY AND HISTOCHEMISTRY OF Tillandsia usneoides (L.) L.

“…The vascular plants of this environment can form clumps and soil islands, in which the microclimatic conditions are mitigated, resulting in increased organic matter, litter, and sediment (Carmo and Kamino, 2015). Species of Bromeliaceae, such as Dyckia excelsa Leme, D. leptostachya Baker, and Deuterocohnia meziana Kuntze ex Mez., occur on rocky outcrops in the city of Corumbá and Ladário (MS), forming groups in soil islands in most cases (Pott and Pott, 1994;Paggi et al, 2015).…”

Cultivable bacterial diversity associated with bromeliad roots from ironstone outcrops in central Brazil

et al. 2020

Studies on the bacterial diversity associated with wild plants are rare, especially on those that grow in association with bromeliads. In the present study, we isolated and identified epiphytic and endophytic bacteria from the roots of the bromeliads Dyckia excelsa, Dyckia leptostachya and Deuterocohnia meziana occurring in the “cangas” in the Pantanal from Mato Grosso do Sul State, Brazil. The epiphytic bacteria were isolated from washed roots, while the endophytic bacteria were isolated from surface disinfested roots. Bacterial representatives corresponding to each BOX-PCR fingerprint, as well as those that did not result in amplicons, were selected for 16S rDNA gene sequence analysis. The BOX-PCR data showed intrageneric and intraspecific diversity and could discriminate strains and identify their phenotypic characteristics. The 16S rDNA gene sequence and phylogeny analysis showed a higher occurrence of strains belonging to the genus Bacillus than Mycobacterium and Brevibacterium, which were found in lower numbers. Species from the Bacillus genus are well known for their sporulation capacity and longer survival in arid locations, such as the “cangas”. This study clearly showed that the bromeliad species represent a vast reservoir of bacterial community diversity, and the cultivable strains represent a new source for biotechnological prospecting.
