Encholirium is an exclusively Brazilian genus of Bromeliaceae that occurs principally in the South American dry diagonal, with only a few species found on inselbergs within the Atlantic Forest. The center of diversity of the genus falls within the Campos Rupestres of the Espinhaço Range of the state of Minas Gerais, followed by rocky outcrops found within the Caatinga and Cerrado biomes. Three new species are described and illustrated, two of which occur on limestone outcrops in western Bahia (Encholirum splendidum and Encholirium fragae), while the third, Encholirium kranzianum, occurs in the Campos Rupestres of the Espinhaço Range of Minas Gerais. © 2015 Magnolia Press.

Genetic concepts within the Bromelioideae are highly problematic, in particular within the tank-forming "core bromelioid" clade. Previous molecular studies showed that the largest genus, Aechmea, and allied genera are polyphyletic and require revision. Here we focus on one group within the Aechmea alliance, the Portea/Gravisia group. To assess whether species of this group form a distinct lineage within the core bromelioid clade, and to clarify generic limits and interspecific relationships within the group, we generated and analyzed amplified fragment length polymorphisms (AFLP). In total, 69 species were sampled, including 26 species previously assigned to the Portea/Gravisia group. Neighbor joining, maximum likelihood and Bayesian analyses of the AFLP data consistently retrieved the Portea/Gravisia group as a monophyletic clade with several subclades, comprising species from the genera Aechmea, Canistrum and Portea. The phylogenetic distribution of polyporate pollen of the resulting trees indicates this character state arose once within the core bromelioids and thus can be regarded as a synapomorphy for the Portea/Gravisia clade. Further, our study shows that within the Portea/Gravisia group, subclades are characterized by petal color and geographic distribution. Thus, the present study is a further advance in the challenging task of elucidating phylogenetic relationships within the core bromelioids as the basis for a revised taxonomy of this ecologically important group. © Copyright 2015 by the American Society of Plant Taxonomists.

We describe and illustrate 10 new Dyckia species from the Brazilian states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais and Paraná: Dyckia acutiflora, D. areniticola, D. formosensis, D. glabrifolia, D. gouveiana, D montezumensis, D. pottiorum, D. rondonopolitana, D. secundifolia and D. walteriana. The morphological affinities of the new taxa are also discussed. © 2012 Magnolia Press. Source

Two new species of Encholirium from the Espinhaço range, restricted to the Diamantina plateau of Minas Gerais state, Encholirium pulchrum Forzza, Leme & O. B. C. Ribeiro and Encholirium diamantinum Forzza, are described and illustrated, and their morphological characters are discussed and compared to those of close relatives. © 2012 The Authors.
