New national and regional bryophyte records, 22

folium and S. recurvum have similar ranges and ecology. In S. angustifolium the stem leaves are more triangular and rarely erose while the branch leaves are narrower and more strongly 5-ranked (McQueen & Andrus, 2006). Sphagnum recurvum also has narrower and more distinctly 5-ranked branch leaves than S. flexuosum, as well as a much more strongly differentiated stem cortex. In S. flexuosum the branch leaves are only slightly recurved when dry whereas in S. recurvum they are sharply recurved (McQueen & Andrus, 2006). Until now, none of these species of the European S. recurvum complex has been identified in the Azores.

Musgos (Bryophyta) de um fragmento de Mata Atlântica na Serra da Jibóia, município de Santa Terezinha, BA, Brasil

This work presents the results of an inventory of mosses carried out in an Atlantic Forest fragment in the Jiboia Mountains, Santa Terezinha, Bahia State, Brazil. A total of 61 moss species distributed in 23 families and 46 genera were found. The families Sematophyllaceae (seven spp.), Orthotrichaceae (six spp.), Pilotrichaceae (five spp.), Calymperaceae (five spp.), Leucobryaceae (five spp.) and Meteoriaceae (four spp.) had higher species richness. Actinodontium integrifolium (Broth.) Churchill and Calymperes venezuelanum (Mitt.) Pitt. are new records for Brazil. Ectropothecium leptochaeton (Schwaegr.) W.R. Buck., Eulacophyllum cultelliforme (Sull.) W.R. Buck & Ireland, Fissidens santa-clarensis Ther., Mittenothamnium reptans (Hedw.) Card., Orthostichella pentasticha (Brid.) Buck, Pilotrichella flexilis (Hedw.) Angstr., Lepidopilidium portoricense (Mull. Hal.) Crum & Steere, and Thuidium tomentosum Schimp. are new records for Bahia. As regards geografic distribuition, neotropical taxa predominate, while in relation to communities, corticicolous (70%) and epixilous species (23%) predominate. The local flora was considered rich for including 24% of the bryophytes that occur in Bahia State.

Species richness and distribution of bryophytes within different phytophysiognomies in the Chapada Diamantina region of Brazil

The Chapada Diamantina ecoregion is within the caatinga (shrublands) biome of Brazil. Environmental factors determine the phytophysiognomies that distinguish the ecoregion from the surrounding areas. This study aimed to investigate the distribution of bryophyte flora in this ecoregion, by phytophysiognomy and elevational zone. Analyzing specimens we collected from five municipalities in the region, together with specimens (previously collected from the region) in herbaria, we identified 400 taxa. The phytophysiognomies that presented the highest species richness and the greatest numbers of exclusive taxa were forests and campos rupestres (dry, rocky grasslands), which respectively accounted for 51% and 40% of the taxa, compared with only 5% and 4%, respectively, for the caatinga and cerrado (savanna). Species richness and the numbers of exclusive taxa were highest in the lower and upper montane zones. There was a predominance of neotropical taxa and a significant number of disjunct species found in Brazil and in the Andes region. We conclude that the Chapada Diamantina region is an important center of bryophyte diversity, harboring not only a great number of species overall but also a considerable number of species exclusive to the region, primarily in forests and campos rupestres at elevations above 800 m.

Cheilolejeunea ornata (Lejeuneaceae), a new species from Brazilian Atlantic Forest

The genus Cheilolejeunea (Spruce) Schiffn. is represented by 16 species in Brazil (Gradstein & Costa, 2003; Bastos & Gradstein, 2006; Bastos, 2009). The most important generic character is the reduction of the first lobule tooth, making the hyaline papillae distal in position to the second tooth. In recent years, some new neotropical species of the genus Cheilolejeunea were described, increasing the number of species for this biogeographic region: Cheilolejeunea norisiae Dauphin & Gradst. from Panama (Dauphin & Gradstein, 2003), Cheilolejeunea lacerata C. Bastos & Gradst. from Brazil (Bastos & Gradstein, 2006) and Cheilolejeunea neblinensis Ilkiu-Borges & Gradstein from Venezuela (Ilkiu-Borges & Gradstein, 2008). Furthermore, a new record for Brazil was published by Bastos (2009): Cheilolejeunea compacta (Steph.) E. Reiner. While studying the genus in Brazil, an apparently undescribed species was detected from Atlantic Forest in Bahia State, Northeastern Brazil. Cheilolejeunea ornata C. Bastos sp. nov. (Figure 1).

Androecia on a short-specialized lateral branch with 2–3 pairs of bracts, lobule strongly inflated, hypostatic, keel strongly crenulate by projecting papillose cells, bracteoles restricted to the base of branch. Gynoecium not seen. Vegetative reproduction by cladia. Corticolous, sometimes mixed with Symbiezidium barbiflorum (Lindenb. & Gottsche) A. Evans, in the Atlantic Forest of southern Bahia, northeastern Brazil. Because of the pointed leaf apex, C. ornata is a member of Cheilolejeunea subgenus Strepsilejeunea (Spruce) R.M. Schust. The new species strongly resembles the neotropical C. oncophylla (Ångstr.) Grolle & E. Reiner, with which it has several characteristics in common (small plants, remote and small underlaeves, vegetative reproduction by cladia). However, C. ornata differs from C. oncophylla by the following features: (i) strongly papillose lobe cells (mammillose in C. oncophylla) (ii) lobe apex acute to apiculate and curved (obtuse to acute, plane or slightly curved in C. oncophylla); and (iii) dioicous plants (C. oncophylla is autoicous).

New combinations and synonyms in Cheilolejeunea (Spruce) Schiffn. (Lejeuneaceae, Marchantiophyta)

In the course of studies on the neotropical species of the genus Cheilolejeunea (Spruce) Schiffn., types and additional materials of several species described by Spruce (1885) and Stephani (1913, 1914) in Cheilolejeunea, Lejeunea Lib., and Trachylejeunea (Spruce) Schiffn. were examined. The results indicated the need to establish several new combinations and synonymies. Gradstein & Ilkiu-Borges (2009) synonymized the genus Trachylejeunea with Cheilolejeunea and created new combinations for most species. However, some of the Trachylejeunea taxa that were only known from the type material were not transferred. Also, the common African species Cheilolejeunea principensis Steph. (C. serpentina (Mitt.) Mizut) was proposed as a ‘provisional synonym’ of Cheilolejeunea rigidula (Mont.)

Type studies on Cheilolejeunea (Spruce) Schiffn. (Lejeuneaceae): Brazilian species described by Stephani

The genus Cheilolejeunea is well represented in Brazil, with more than 20 species described. However, a revision of Brazilian Cheilolejeunea species is timely, since there have been no recent taxonomic studies on the genus in Brazil. Some species described by Stephani (1896, 1913, 1914) and reported from Brazil (Yano, 1984, 1989, 2008; Gradstein & Pinheiro da Costa, 2003) have not been collected subsequently. These species are known only from Stephani’s descriptions and type specimens. In this study, some of the species described by Stephani (1896, 1913, 1914) belonging to Strepsilejeunea and Cheilolejeunea have been examined and several new combinations are proposed here, together with a new name for Strepsilejeunea lindenbergii Steph. Accordingly, nomenclatural updates, illustrations, descriptions, and comments on the geographical distribution in Brazil are provided as appropriate. Strepsilejeunea brotheri Steph. is treated here as synonymous with Pluvianthus squarrosus (Steph.) R.M.Schust. & Schäfer-Verw., Strepsilejeunea simplex Steph. was found to be a synonym of Cheilolejeunea oncophylla (Ångstr.) Grolle & E.Reiner, and Strepsilejeunea theriotii Steph. is synonymous with Cheilolejeunea acutangula (Nees) Grolle. Cheilolejeunea bahiensis Gottsche ex Steph. proved to be Lejeunea flava (Sw.) Nees, and Cheilolejeunea rosana Gottsche ex Steph. is merged with Lejeunea puiggariana Steph. The type specimens of Cheilolejeunea bahiensis, Cheilolejeunea grandibracteata Steph., Cheilolejeunea rosana, Strepsilejeunea brotheri, Strepsilejeunea lindenbergii, Strepsilejeunea simplex, and Strepsilejeunea therriotii were borrowed from the Conservatoire et Jardin Botaniques de la Ville de Genève (G).

Several populations of Cheilolejeunea acutangula were examined and compared with the type specimen of Strepsilejeunea theriotii. There are insufficient morphological differences to justify the retention of these two taxa as distinct species. S. theriotii is accordingly merged with C. acutangula. Grolle (1979) provided a comprehensive discussion on C. acutangula, but no illustrations were given. Cheilolejeunea grandibracteata Steph., Spec. Hepat.: 5: 657. 1914.
