The present study describes and illustrates two newly identified moss species of Brachymenium, endemic to the Atlantic Rainforest of the South and Southeastern regions of Brazil. The first is Brachymenium elimbatum, a medium-sized plant with leaf apex ending in a short to long arista, margins not bordered, plane, entire, costa tapering above and sub-percurrent. The second is Brachymenium sublineare, a medium-sized plant with leaves often asymmetrically curved in the distal half, margins bordered by 1–3 rows of narrow rectangular cells and serrate at distal half, costa short-excurrent, flagelliform branches occasionally present and exostome teeth sub-linear. A key is presented with the most similar Brazilian Brachymenium species.

Epiphytic Bromeliads

Many Brazilian Atlantic Rainforest plant and animal species are geographically restricted to Southern Bahia and Northern Espírito Santo States. We investigated the geographic distribution of epiphytic bromeliads in the lowland forest of the Una region (15° 17' 34' S - 39° 04' 30'' W) in Southern Bahia. Specifically, we addressed the following questions: i) what is the extent of each species distribution?; and ii) are the Bromeliaceae subfamilies distributed differently from one another? Almost half of the 40 species (47.5%) occur exclusively in the Southern Bahia-Northern Espírito Santo region and are herein referred as endemic species. The highest percentage of the 15 species of Tillandsioideae (46.7%) occur throughout the South American Continent and most of the 25 species of Bromelioideae (68.0%) are mainly represented by endemic species. The Una region has almost two times more species than a forested area located 40 km west, suggesting marked increases in diversity in over relatively short distances. The endemism data around Una indicates that species are geographically distributed over an area spanning approximately six to seven degrees in latitude and longitude. This result contrasts with the geographic distribution of Andean epiphytes, mainly represented by Tillandsioideae, that have large geographical distributions. Larger-scale analyses and standardized methods are necessary to verify whether the narrow geographical distribution of most epiphytic bromeliads in the Una region is consistent across different forest types of the Atlantic Rainforest.

Abstract After the publication of the book entitled “Recollection of Gyula E. Nyárády” (2016), the interest of his inheritance increased significantly. His left behind herbarium was estimated to have 55,000 sheets (1988), while till 2016 its number increased up to 85,000. The herbarial investigations are taking place over the Romania’s borders too, such as in the plant collection of the Debrecen University. With this occasion, we have studied the part collections of Rezső Soó (40,000 specimens), the Zoltán Siroki’s (20,000 specimens), together with the kryptogame (3,000 bryophytes) ones. In the Debrecen University plant collection we found 166 plant species collected and determined by E. Gy. Nyárády, among them 154 are superior plant and 12 are moss. In the Soó collection 112 plants arose from E. Gy. Nyárády, 69% of them are from Slovakia, 29% from Romania and 1% from Poland. The Slovakian collections took place in the 1905-1916 period, the most of them (34 species) are from 1910, being collected in Késmárk and Tatra’s region, where E. Gy. Nyárády was secondary school teacher. The Romanian collections took place in the 1905-1942 period, the 33 species mainly arise from the high mountains (especially Rodna Mountains), as well as from the Transylvanian Plain. We have found three endemic species among them: Festuca carpathica Dietr., Koeleria transsilvanica Schur (syn. Koeleria macracantha ssp. transsilvanica (Schur) A. Nyár., and Thymus pulcherrimus Schur. In the Siroki collection there are 42 plant sheets, originated from Slovakia, from 1908-1913 period. The four Romanian plants came from the Rodna Mountains. The Kryptogam Herbarium contains 12 Romanian moss species, collected between 1925 and 1929, most of them being from Székelyudvarhely (Odorheiu Secuiesc). The genus Carex occurs most frequently in the Nyárády-collection, due to his increased interest to sedges, forming 39% of the studied species. In accordance with the labels, in his collecting trips he was occasionally accompanied by Béla Husz (1911, Szepes) and Ádám Boros (1929, Korond).

Abstract We report on a recent collection of caridean shrimps from St. Helena in the south-central Atlantic Ocean, raising the total number of species known from the island to 24. Six species are newly recorded for the area, with no endemic species present. Additional three species are recorded from Ascension Island. A close biogeographical connection between the caridean faunas of St. Helena and Ascension Island is evident.

The worker, queen and male of the ant Typhlomyrmex meire Lacau, Villemant & Delabie new spe- cies (Ectatomminae: Typhlomyrmecini) are described from the Brazilian Atlantic rainforest. This endemic species from southern Bahia is easily distinguished from all other members of the genus by the peculiar morphology of mandibles and the reduction of the antennal segments observed in both sexes. We provide a partial redefinition of the genus diagnosis taking into account the antennal structure of the new species. A new identification key for workers is provided.

The Nahanni and Liard mountain ranges are located at about 61° N latitude and 122° W longitude. They form the easternmost slopes of the Rocky Mountains and lie just east of Nahanni National Park in the southwestern corner of the District of Mackenzie, Northwest Territories. The moss flora of the area is rich in the number of taxa; 207 species and two varieties are reported from this relatively small area. Of these, 53 species are new records for the South Nahanni region. A number of rare or disjunct bryophyte species are found in the area. Moss species which are either disjunct or occur at the edge of their range include Arctoa fulvella (Dicks.) B.S.G., Aulacomnium acuminatum (Lindb. & Arn.) Kindb., Andreaeobryum macrosporum Steere & B. Murray, Geheebia gigantea (Funck) Boul., Isopterygiopsis muelleriana (Schimp.) Iwats., Mnium spinosum (Voit) Schwaegr., Psilopilum cavifolium (Wils.) Hagen, Rhabdoweisia crispata (With.) Lindb., Seligeria calcarea (Hedw.) B.S.G., S. polaris Berggr., Trematodon brevicollis Hornsch., and Trichostomum arcticum Kaal. The North American distribution of these species is mapped. Herbertus stramineus (Dum.) Trev., Metacalypogeia schusterana Hatt. & Mizut., Scapania crassiretis Bryhn, and S. simmonsii Bryhn & Kaal. are four hepatic species of phytogeographic interest.

Abstract The bryoflora of Brazil comprises 1,524 species, 117 families, and 413 genera (11 hornworts, 633 liverworts, and 880 mosses). The most diverse families of liverworts are: Lejeuneaceae (285 species), Lepidoziaceae (48), Frullaniaceae (37), Ricciaceae (36), Plagiochilaceae (27), Radulaceae and Metzgeriaceae (26 each), Lophocoleaceae (18), Aneuraceae (15), and Calypogeiaceae (13); while, for the mosses, we have: Sphagnaceae (83 species), Fissidentaceae (65) Pottiaceae (63), Dicranaceae (54), Bryaceae and Sematophyllaceae (53 each), Orthotrichaceae and Pilotrichaceae (51 each), Calymperaceae (48), and Hypnaceae (28). These large groups account for 71% of the Brazilian bryophyte species. Lejeuneaceae and Sphagnaceae are the families with highest number of endemic taxa (54 and 60 species). The Atlantic Rainforest presents the greatest number of species (1,337), followed by the Amazon Rainforest (570) and Cerrado (478). The highest number of endemic species (242) is associated with the Atlantic Rainforest, where the Dense Ombrophilous Forest concentrates 73% of the species with 62% endemism. The Southeastern region is the most diverse in number of species (1,228) and with more endemism (219). Most endangered species are restricted to the Atlantic Rainforest of southeastern Brazil, which is the diversity and endemism centre for mosses and liverworts. The information currently presented by the Brazilian List is close to the real bryophyte diversity found in the country.

Hibiscus L. is one of the largest genera of Malvaceae, Southeast Brazil has six endemic species of 14 native species, mainly distributed in cerrado. These Hibiscus are hairy shrubs, with showy flowers of pink corolla, dark base, 5-toothed staminal tube apex, loculicidal capsule of 5 cells. The species inhabit wet ecosystems of the atlantic rainforest and cerrado. After the last study of Hibiscus taxonomy evidencing four endemic species from Minas Gerais state, showed to have the largest endemism center of Hibiscus in Brazil, therefore, using IUCN classification methodology, we indicated H. hilarianus and H. multiformis as vulnerable, H. itirapinensis as endangered and H. mariae as critically endangered. The species are represented by small isolated populations distributed at the mountains and plateaus between Espinhaço mountain range and Planalto Paulista, considered a region with great endemic biodiversity. According to the previously analysis, it is recommended specific studies with techniques and appropriate methodology to research the development and evolutionary characteristics of hibiscus species in Minas Gerais state.
