The present study consists of the floristics-taxonomic survey of Bromeliaceae and Orchidaceae on rocky outcrops located at an Atlantic Forest-Caatinga transition area in Paraíba State, northeast of Brazil, in order to provide data for the implementation of the biota conservation’s policies, especially of the flora associated to rocky environments of Paraíba State, given that the taxonomic studies focusing on such families in this state are still incipient. During the study, ten species in six genera of Bromeliaceae and six species in five genera of Orchidaceae were recorded. The treatment includes keys for recognition of the species of families, morphological descriptions, illustrations, geographic distribution data, and comments on the phenology of the species.
New occurrence records of Bromeliaceae for the state of Maranho, northeastern Brazil
Check List, 2020
We report three species of Bromeliaceae (Encholirium spectabile Mart. ex Schult. & Schult.f., Pitcairnia burchellii Mez, and Tillandsia bulbosa Hook.) for the first time from Maranhão, northeastern Brazil, based on our fieldwork. Data on species’ morphology, taxonomy, ecology, and geographic distribution are included. Our new data add to the knowledge to the flora of Maranhão and expand the distribution of three bromeliad species in Brazil.
Floristic diversity of two crystalline rocky outcrops in the Brazilian northeast semi-arid region
Brazilian Journal of Botany, 2010
Floristic composition and structure of vegetation were studied in two rocky outcrop areas in the semi-arid region of northeastern Brazil. From April 2007 to September 2008, 18 monthly field trips were carried out. Vascular plants were randomly collected throughout the outcrop areas. For structural analysis, 30 plots of 1 × 1 m were set in the vegetation islands. The checklist presented combines 211 species (69 families and 168 genera), although only 56 species were collected in the plots. Fabaceae (18 spp.; 8.5%), Asteraceae (17 spp.; 8%), Orchidaceae (13 spp.; 6.1%), Euphorbiaceae (13 spp.; 6.1%), Bromeliaceae (10 spp.; 4.7%), and Poaceae (eight spp.; 3.8%) are the richest families. Overall, 1,792 shrub and herbaceous specimens were counted in the plots. The Shannon-Wiener (H) diversity index values were 2.572 and 2.547 nats individual-1. The species that presented the highest absolute abundance values (number of plants) had low frequencies in the plots and vice-versa. The biologic...
Miscellaneous new species in the Brazilian Bromeliaceae
Rodriguésia
From 1990 to 2006, 2,875 new angiosperm species were described in Brazil, including 280 newBromeliaceae species. This publication rate is considered to be a useful indicator of floristic richness andalso reveals the huge gaps in our knowledge of species that make up Brazilian biomes and the importanceof taxonomy as a basic tool to assess biodiversity and conservation. The goal of modern taxonomists is ina race against time ordained by an unprecedented rate of global biodiversity loss, and therefore collaborationis vital to successfully close these gaps. This paper is the result of a broad cooperative research effortundertaken specifically to provide basic data on the identity of new components of Brazilian biologicaldiversity. The authors describe and illustrate 22 new Bromeliaceae species from three subfamilies: Bromelioideae - Aechmea guaratingensis, A. paratiensis, A. rubroaristata, Cryptanthus capitellatus, C. venecianus, C. viridovinosus, Hohenbergia aechmeoides, H. arcuata, H....

Bromeliaceae is one of the most representative plant families in restinga habitats. We analyzed the species richness and composition of Bromeliaceae in 13 restinga habitats along the Brazilian coast. We found a total of 41 species distributed along the restinga habitats studied. The restinga of Praia do Sul, in the state of Rio de Janeiro, had the highest number of species (15), whereas the restinga of Abaeté, in the state of Bahia, had the lowest (4). Our data are suggestive that the Doce River may represent the limit of distribution for some bromeliad species, with some species occurring only south of that river and others occurring only to the north of it. The differences in Bromeliaceae species composition among restinga habitats probably are not only due to differences in local environmental conditions, but also due to the geographic distribution pattern of each species and to the present degree of disturbance at each restinga.

A taxonomic treatment for Boraginales (Boraginaceae s.l.) and Lamiales (Lamiaceae and Verbenaceae) in the Engenheiro Avidos Ecological Park, a full-protection reserve located in the semiarid region of Paraíba State in northeastern Brazil is presented in this study. At the Park, a total of 22 species were encountered, including nine species of Boraginaceae s.l., six species of Lamiaceae, and seven species of Verbenaceae. Vitex orinocensis (Lamiaceae) was found for the first time for Caatinga and also represents a new record for Paraíba state. Morphological descriptions, keys for separating the families and respective species; data concerning flowering, fruiting, geographic distributions, and of the preferred habitats of the species found in the study area are also provided.
