Heliotropium L. (Boraginaceae - Heliotropioideae) de Pernambuco, Nordeste do Brasil,

A taxonomic study of the genus Heliotropium L. in the State of Pernambuco was carried out. The survey was based on field studies during 16 months and material provided by loan and donation from different brazilian herbaria. Seven species were recorded: H. angiospermum Murray, H. curassavicum L., H. elongatum (Lehm.) I.M. Johnst., H. indicum L., H. polyphyllum Lehm., H. procumbens Mill. and H. ternatum Vahl. H. curassavicum and H. ternatum represent new geographical occurrences from Northeastern and State of Pernambuco, Brazil, respectively. The species most widely distributed were H. angiospermum, H. elongatum and H. procumbens , occurring both since litoral to caatinga ́s zone. Key-words: Heliotropium, Boraginaceae, taxonomy, Northeastern, Brazil

was performed in the region of the influence area of the Xingo hydroelectric, situatedunder the domain of semi-arid region in northeastern Brazil. The predominant vegetation at the study area isCaatinga but phytosociological approaches for this area are lack. Eight species were found distributed inthree genera:

Composição e similaridade da flora sssociada a sítios antropizados do município de João Pessoa - Paraíba

This study presents the floristic composition and similarity of synanthropic vascular plant species in an anthropogenic peri-urban area in the city of Joao Pessoa, in the state of Paraiba, and how it is related to other synanthropic floras. A total of 98 species in 75 genera and 30 families were found. Among the species, 41.84% are cosmopolitan, 29.6% pantropical, 13.3% occur only in the Southern Cone of America, 8.2% are Neotropical, 5.1% gondwanic and 2% occurs across America. Asteraceae and Poaceae were the families with the biggest number of species. The results were compared with other related floristic surveys using SA¶rensenâ€(tm)s similarity coefficient, and it was observed that not it is only the geographical proximity of the two locations that reflects a higher floristic similarity between areas but also the extent of the taxa and the presence of a similar microhabitat. The study focuses on an area located in the Brazilâ€(tm)s Midwest region.
