Angiosperm Checklist of Espírito Santo: using electronic tools to improve the knowledge of an Atlantic Forest biodiversity hotspot

A checklist of angiosperm species for the state of Espirito Santo, Brazil is presented. A total of 6,204 native species was recorded, representing an increase of 16% in species richness for the area. Espirito Santo shelters 32% of the native species of Brazils Atlantic Forest and holds 516 endemic species (8.3% of the total registered taxa for the State). Bromeliaceae and Orchidaceae are the families with highest number of endemic species (142 spp. and 80 spp., respectively), followed by Myrtaceae (33 spp.), Melastomataceae (30 spp.), and Araceae (23 spp.). This paper represents an important landmark for future research in plant diversity in Espirito Santo, and highlights the importance of consulting online databases in order to update the knowledge presented by the Brazilian flora checklist.

Checklist de Angiospermas do Parque Estadual de Itaúnas, Espírito Santo, Brasil

This paper provides a floristic inventory of Angiosperms reported from Parque Estadual de Itaunas, Espirito Santo, Brazil. The inventory was performed with fortnightly fieldwork from 2012 to 2015. The samples collected are available at the herbarium VIES. A checklist with 562 species, from 345 genera and 110 families is provided. Lifeforms categories were established: shrubs and trees; terrestrial herbs; herbaceous and woody climbers; epiphytes and hemiepiphytes; aquatic herbs, parasites (holo- and hemi-), and myco-heterotrophs (saprophytes). Fabaceae, Myrtaceae, Cyperaceae, Rubiaceae, Bromeliaceae, Apocynaceae, Orchidaceae, Poaceae, Bignoniaceae, and Melastomataceae presented the greatest species richness. The genera Eugenia (16 spp.) (Myrtaceae), Passiflora (10 spp.) (Passifloraceae), Myrcia (9 spp.) (Myrtaceae), Cyperus (7 spp.), and Chamaecrista (Fabaceae) and Miconia (Melastomataceae) (6 spp., each) presented the greatest species richness. Most of the previous checklists elaborated in the Espirito Santo state have underestimated plant species diversity. This floristic inventory confirms the ecological value of the restingas in the Atlantic Forest located at Parque Estadual de Itaunas.

Angiosperms from rocky outcrops of Pedra do Elefante, Nova Venécia, Espírito Santo, Brazil

Abstract We provide a floristic inventory of Angiosperms from rocky outcrops of the Area de Protecao Ambiental Pedra do Elefante, Espirito Santo, Brazil. Fieldwork was performed monthly from March/2015 to July/2016. A checklist with 302 species belonging to 219 genera and 74 families is provided. Bromeliaceae, Orchidaceae, Fabaceae, Euphorbiaceae, Apocynaceae, Asteraceae, Cactaceae, Convolvulaceae, Rubiaceae, Bignoniaceae and Cyperaceae are the richest families with around 50% of the listed species. One hundred forty seven species are exclusively rupicolous, 125 spp. exclusively terricolous, 26 spp. are epiphytes, and six species are found as both rupicolous and terricolous. Phanerophytes and chamaephytes were predominant life forms. Our results added 18 new records to the Espirito Santo state, indicated the occurrence of nine endemic species for the state and noticed that only 55 taxa of the total of species have threat assessments according to IUCN. Key words : Atlantic rainforest, floristic inventories, inselberg, neotropics.

Flora do Espírito Santo: Mimoseae (Leguminosae): parte 1

Tribe Mimoseae (Mimosoid clade Leguminosae) has 41 genera and about 860 species, of which, 16 genera and 614 species are recorded in Brazil. As a very representative group from Brazilian flora and from Atlantic Rainforest, this paper aims to provide the floristic and taxonomic treatment for genera Anadenanthera, Leucaena, Neptunia, Parapiptadenia, Parkia, Piptadenia, Plathymenia, Pseudopiptadenia, and Stryphnodendron from Espírito Santo state (ES). Fieldwork was performed from April 2014 to July 2015 and vouchers housed at herbaria were examined. A total of 24 taxa (22 species and two varieties) were found in the state. Piptadenia (six spp.), Pseudopiptadenia (six spp.), Stryphnodendron (three spp.), and Anadenanthera (two spp.) are the richest genera amongst analyzed. Leucaena, Neptunia, Parapiptadenia, Parkia, and Plathymenia were represented by only one species each. Compared to the previously known for ES, results increased two genera and nine taxa (specific and infraspecific), as follow: Anadenanthera colubrina var. cebil, A. colubrina var. colubrina, A. peregrina var. peregrina, Neptunia plena, Piptadenia santosii, Pseudopiptadenia bahiana, P. psilostachya, Stryphnodendron polyphyllum, and S. pulcherrimum. Identification keys, descriptions, taxonomic comments, illustrations, and geographic distribution maps are provided.

Macrófitas aquáticas do Parque Estadual de Itaúnas, Espírito Santo, Brasil

Macrophytes are organisms that have active photosynthetic parts and may be permanently or seasonally submerged, or floating. Given the ecological and physiognomic relevance of the group, this study aimed to determine the richness of aquatic plants from the Parque Estadual de Itaúnas (PEI), Espírito Santo, Brazil, and its floristic links with other areas in the Atlantic Forest. A total of 66 species, 48 genera and 31 families of aquatic macrophytes were found for PEI, of which two are unpublished records for Brazil (Sesbania herbacea and Utricularia biloba), five for the state (Ipomoea bahiensis, Ludwigia cf filiformis, Ludwigia hyssopifolia, Mollugo verticillata, Paspalum repens) and 49 new occurrences for PEI. Most of species are represented by angiosperms and only three species belong to Ferns and Licophytes. The similarity analysis results revealed two groups, one formed exclusively by areas considered as “restingas” while another is composed by areas with different plant physiognomies. Thus, new records allied to the low similarity of species composition make evident the importance of the area for the conservation of aquatic macrophytes from the Atlantic Forest.

New records of Pouteria macrocarpa (Sapotaceae) from the Brazilian Atlantic forest

Abstract We present the first voucher-based record of Pouteria macrocarpa for Brazilian Atlantic forest and extend the occurrence area of it. Besides, a brief taxonomic description, an identification key for lignified-fruits Pouteria species, and information about phenology and herbarium records are provided. According to the IUCN Red List and the Red Book of the Brazilian Flora, the species is considered Vulnerable (VU). However, facing the new available data, we believe it should be reassessed as Endangered (EN). Key words : Brazil, Chrysophylloideae, Ericales, Espirito Santo, Neotropics.

Flora do Espírito Santo: Micropholis (Sapotaceae-Chrysophylloideae)

Abstract Herein, we provide information about morphological data, geographic distribution and conservation status for native species of Micropholis from Espirito Santo state (ES), Brazil. A total of five species were found: M. compta , M. crassipedicellata , M. gardneriana , M. guyanensis subsp. guyanensis , and M. venulosa . They represent 100% of the known species of Micropholis from the Brazilian Atlantic rainforest. The most important characters for distinguishing the species are: type and color of indument on the young branches, leaf shape, midrib sunken or not on the upper leaf surface, distinguishable secondary veins from the tertiary ones. Micropholis gardneriana constitutes a new record for the Espirito Santo state. Amongst Micropholis species from ES, only Micropholis compta is considered as Near Threatened (NT). Key words : Ericales, Atlantic rainforest, neotropics, taxonomy. Flora do Espirito Santo: Micropholis (Sapotaceae-Chrysophylloideae) 1 Flora of the Espirito Santo: Micropholis

Checklist of Sapotaceae in Northeastern Brazil

The Sapotaceae are a pantropical family of flowering plants composed of approximately 1,250 species. In Brazil, the Sapotaceae are represented by 11 genera and 231 species, 86 of which have been registered in the region of northeastern Brazil. This paper provides a checklist of the Sapotaceae species that occur in a major portion of northeastern Brazil, and aims to document the number of native taxa, update their currently accepted names, and contribute to the Flora of Brazil (Lista de Especies da Flora do Brasil). Additional information about regional geographic distribution, biomes of occurrence, IUCN status, and vernacular names are provided for each species. A total of nine genera and 46 species were documented and the majority (64%) is restricted to the Atlantic Rainforest. The current study provides an important contribution to our knowledge of the Sapotaceae in the Atlantic Rainforest biome.
