title: Pollen morphology of species of Bonamia Thouars, Evolvulus L. and Jacquemontia Choisy (Convolvulaceae) occurring in an ecotone region in the municipality of Caetité, Bahia State, Brazil

description: ABSTRACT The pollen morphology of 17 taxa of Convolvulaceae [Bonamia agrostopolis, Evolvulus (nine species) - Tribe Cresseae), and Jacquemontia (seven species) - Tribe Jacquemontieae)] was described under light microscopy (LM) and scanning electron microscopy (SEM) with the objective of contributing to the palynology and the taxonomy of the group. The pollen material was collected from anthers and/or floral buds of herbarium exsicates, acetolyzed, analyzed quantitative and qualitatively under LM and SEM, described and illustrated. The data presented here on the pollen morphology of the studied Bonamia, Evolvulus and Jacquemontia species, showed that B. agrostopolis has medium, isopolar, microechinate, granulated pollen grains with the 3-colpate apertural type, which is present in the majority of Jacquemontia species studied. On the other hand, Evolvulus species, J. gracillima and J. pentanthos have the same pollen type, characterized by being spheroidal, pantocolpate and microechinate. The other species of Jacquemontia were characterized by the subprolate to prolate-spheroidal shape, and the zonocolpate and microechinate exine in the pollen grains of all species, with granules, perforations, and micro-reticules in some species. We observed a lack of definition of the pollen types that delimit Cresseae and Jacquemontieae since there are palynological affinities between species of the two tribes. The species of Evolvulus form a stenopalynous group; however, the present study presents unpublished palynological descriptions for nine species, contributing to the expansion of pollen data and confirming the eurypalynous character of Convolvulaceae.

title: Pteridophytes used in legislation as indicators of successional stages in Santa Catarina State, Brazil

description: ABSTRACT In the State of Santa Catarina, three resolutions of the Environment National Council (CONAMA) characterize the successional stages of plant formations for environmental licensing: 04/1994 (forests), 261/1999 (restinga), and 423/2010 (high altitude grasslands), showing indicator taxa, including pteridophytes. We evaluated the quality of indication of the 14 pteridophytes adopted as indicators of successional stages in these resolutions (six species in 261/1999, nine in 423/2010, and one in 04/1994) and discussed possible indicator species in six genera cited in 261/1999. We created two sets of criteria and, from Herbarium specimens and bibliographic review, applied these criteria to each evaluated species. We considered most species in resolution 261/1999 as a good indicator, as well as five other species (Lomariocycas schomburgkii, Neoblechnum brasiliense, Pleopeltis hirsutissima, Pleopeltis pleopeltifolia, and Serpocaulon latipes). On resolution 423/2010, only Lomariocycas schomburgkii and Pteridium esculentum were considered good indicators, being the last species also good for the early successional stage of forests. Revisions should be made in these resolutions in order to make them more appropriate, mainly incorporating more species to the resolution of forests.

title: Lycophytes and ferns of the Parque Estadual Monte Alegre (PEMA), Pará State, Brazil

description: ABSTRACT The Cerrado is an important phytogeographic Brazilian domain that covers a considerable percentage of the national territory. Although there are few studies highlighting the importance of ferns and lycophytes in the Cerrado, it is estimated that 241 to 248 species occur in this phytogeographic domain. Therefore, the objective of this study was to perform a survey of the Pteridophytes of a Cerrado area, located in the State of Pará and to present an identification key for the species. We used the walking methodology of sampling in areas with terra firme forest on slopes, in rocky outcrops, and at the entrance of caves. We obtained two lycophytes and 18 ferns species, belonging to nine families, being Pteridaceae, Anemiaceae, and Polypodiaceae the most representative. This result was similar to previous studies carried out in this domain. Two species with no herbarium records in the northern region were found: Anemia elegans (Gardner) C. Presl, and Cheilanthes eriophora (Fée) Mett. An identification key for the species using reproductive and vegetative characters was elaborated. Floristic studies including Pteridophytes are important because they contribute with the knowledge about the biology and distribution of this group of plants in the Cerrado, as well as in the Pará flora.

title: Phytosociology of the woody and herbaceous plant assemblages in an area of caatinga in Paraíba State, Brazil

description: ABSTRACT The caatinga sensu stricto is a typical vegetation type of the Brazilian semiarid region and is adapted to strong seasonality in rainfall and high temperatures. It has a high species richness and a high level of beta diversity. The objective of this study was to document the flora and structure of woody and herbaceous plant assemblages of a site with caatinga vegetation. We sampled one hectare in the Reserva Particular do Patrimônio Natural Fazenda Almas (Paraíba State, Brazil). Our study recorded 114 species (34 woody/80 herbaceous), which is similar to other studies conducted in this vegetation type. The woody component presented density of 4822 ind.ha-1 and a basal area of 38,851 m2.ha-1. For the herbaceous plants, we recorded variation in density, percentage of soil cover, and species richness between the dry and rainy seasons. Despite the high biodiversity, the caatinga still undergoes extensive environmental degradation processes. The present study documented the structure of a conserved tract of caatinga that can be a reference for future restoration projects.

title: Floristic and ecological attributes of Restinga shrub formations in key area for biodiversity conservation, Guarapari, Espírito Santo State, Brazil

description: ABSTRACT The water table level has been assuming a prominent role in recent years in studies about the structuring of plant communities in Restinga, which led us to compare the floristic and phytosociological structure between flooded and non-flooded open shrubby formations. The floristic survey and line intercept method were conducted in both the phytophysiognomies. For the phytosociological analysis, two plots of 20 × 150 m, which were subdivided into five subplots of 20 × 30 m, were installed in each phytophysiognomym. A total of 147 bushes were evaluated, 49 from the flooded and 98 from the non-flooded formations, representing, on average, areas of 210.78 m2 and 30.45 m2, respectively. The flooded formation showed an average of 4.9 bushes per subplot, while the non-flooded formation showed an average of 9.8. As a total, 100 species from 40 families were found in the two vegetation types, 87 of them in the flooded and 68 in the non-flooded areas. The most representative families were Orchidaceae and Bromeliaceae. We found a high floristic distinction between the vegetation types, suggesting that the water table level affected the structure of plant communities.

title: Verbenaceae in the Parque Nacional do Caparaó, Serra da Mantiqueira, Brazil

description: ABSTRACT Verbenaceae currently comprises 35 genera and around 800 species distributed in the Americas, Africa, Asia, Europe and Oceania. In Brazil, there are 16 genera and approximately 280 species, with higher richness in the Cerrado and the Atlantic Forest, mainly in campos rupestres and campos de altitude. The Parque Nacional do Caparaó is located in the Serra da Mantiqueira, the border of Minas Gerais and Espírito Santo States. This park stands out due to the presence of the highest point in the Southeast of Brazil, the Pico da Bandeira, with 2,890 m of elevation. The vegetation comprises different phytophysiognomies including dense ombrophilous forest (montane and high montane), montane semideciduous seasonal forest and campos de altitude. Verbenaceae in this conservation unit is represented by five genera and nine infrageneric taxa including two possible new species belonging to the genera Lantana and Lippia, in addition to Citharexylum solanaceum, Glandularia lobata, Lantana fucata, L. nivea, L. robusta, Stachytarpheta cayennensis, and Verbena rigida. The occurrence of L. nivea is confirmed for Brazil, with the first record for Espírito Santo State. We present an identification key, descriptions, photograph plates and comments on the ecology, taxonomy and geographic distribution of the taxa.
