In a taxonomic survey carried out in cerrado vegetation from Alagoinhas county, State of Bahia, 15 species of Bryophyta, were identified distributed into 12 genera and 9 families, and 12 species of Hepatophyta distributed in 7 genera and 2 families. Cheilolejeunea rigidula (Mont. ) Schust., Diplasiolejeunea cobrensis Gott. ex Steph., Diplasiolejeunea rudolphiana Steph., Frullanoides corticalis (Lehm. & Lindenb.) van Slag., Frullania neesii Lindenb., Lejeunea glaucescens Gott. and Leucolejeunea unciloba (Lindenb.) Evans are mentioned for the first time for Bahia and Harpalejeunea stricta (Lindenb. & Gott.) Steph. is new for Brazil.
The moss flora of the state of Bahia is represented by 208 species distributed in 88 genera and 34 families. Of these, 188 have already been recorded for the Bahia. In this paper are reported 18 species of mosses belonging to 16 genera and 12 families (Archidiaceae, Orthotrichaceae, Bartramiaceae, Bryaceae, Thuidiaceae, Sematophyllaceae, Pterobryaceae, Meteoriaceae, Hookeriaceae, Pottiaceae, Calymperaceae and Fissidentaceae) for Bahia and represent an additional contribution to the knowledge of the bryophyte flora of this state.
In this paper are recorded 18 taxa of hepatics (Jungermanniophyta) for the first time for the state of Bahia, Brazil. Of these, Harpalejeunea ovata (Hook.) Schiffn. is new for Brazil. Morphological characters, notes on habitat and substrate are given for each species. Illustrations for Harpalejeunea ovata, Pycnolejeunea callosa (Lindenb.) Steph., Pycnolejeunea macroloba (Nees & Mont.) Schiffn., Rectolejeunea berteroana (Gott. ex Steph.) Evans and Trachylejeunea crenata (Mont. & Nees) Schust. are given.
This paper represents an additional contribution toward the knowledge of a bryophyte flora of Chapada Diamantina National Park in the State of Bahia, Brazil, in which are reported 27 species of mosses belonging to 22 genera and 14 families, and four species of liverworts belonging to four genera and three families. Most of these species seem to be restricted to this high altitude geomorphological complex area.
Four new records of pleurocarpous mosses are reported for the first time for the State of Bahia: Phyllodon truncatulus (Hypnaceae), Trichosteleum brachydictyon, Sematophyllum tequendamense and Potamium lonchophyllum (Sematophyllaceae). These species were found in the Tropical Atlantic Rainforest situated in the South of Bahia.
The caatinga is a deciduous and xerophilous vegetation that covers large areas in Brazil. An irregular rainfall with a marked dry period is a characteristic feature. This paper represents the first contribution to the knowledge of the bryoflora from caatinga vegetation in the State of Bahia. The survey was carried out in several areas from Bahia in which eigthteen species of bryophytes were found (15 mosses and 3 liverworts). The bryoflora from caatinga is composed mainly of generalists and xerophilous taxa, but even some hygrophilous species can be found. A number of species including Hyophiladelphus agrarius, Hyophila involuta, Calymperes palisotii ssp. richardii, Bryum argenteum, Entodontopsis leucostega, Octoblepharum albidum, Frullania ericoides also occur in other vegetation types. However, there are a number of species restricted to this type of vegetation, such as Helicophyllum torquatum and Riccia vitalii, at least in Bahia. Most moss species were acrocarpous with erect and short (short-turf) growth-form, whereas the foliose hepaticae were of incubous, and thallose forms.
