Contributions to the bryological flora of the tropical and subtropical forests from the Argentina (Bryophyta, Musci).

The authors present here a list of 32 mosses belonging to 15 families: Brachytheciaceae, Cryphaeaceae, Entodontaceae, Hedwigiaceae, Hypnaceae, Leptodontaceae, Meteoriaceae, Neckeraceae, Pilotrichaceae, Polytrichaceae, Pterobryaceae, Racopilaceae, Rigodiaceae, Stereophyllaceae, and Trachypodaceae, all collected in the mountainous forests of the Yungas of the NW of the Argentina (Jujuy, Salta, Catamarca and Tucumán provinces), and also in the rainforests from the NE of the country (Misiones province). Eight species: Atrichum polycarpum, Chrysohypnum elegantulum, Pilosium chlorophyllum, Pilotrichella flexilis, Porotrichodendron lindigii, Pseudotrachypus martinicensis, Steerecleus scariosus, and Thamnobryum fasciculatum are new records for the bryologic flora from Argentina. Braunia imberbis and Squamidium brasiliense are two new records for the bryophytic flora of the Catamarca province; Porotrichodendron superbum is new for the Salta province, while Forsstroemia coronata is the first record for the Catamarca and Jujuy provinces. Aerolindigia capillacea, Braunia reflexifolia, Chryso-hypnum diminutivum, Meteorium deppei and Meteoridium remotifolium are five new citations for the Jujuy province, and Schoenobryum concavifolium is new for the bryophytic flora of the Misiones province. Many studied species occur more frequently in the Yungas than in the NE rainforests; others show separated distribution but live in both areas, the Yungas and Paranaense area, and others are more or less restricted to the Paranaense rainforest of the NE of Argentina. The taxonomy of species is updated, and comments are included on bibliographical precedents, ecology and chorology of each taxon.

Floristic notes of Sierra del Rincón Biosphere Reserve (Spain, Madrid province)

New records of vascular plants from Sierra del Rincón Biosphere Reserve and surroundings (Spain, Madrid province) are provided. It is noteworthy the presence of atlantic flora in this continental area and the different shrubby communities in different sectors with different litology: in areas with gneiss they are dominated by leguminous genisteae; where it is schistous, shale or quartzite they are heathlands.

Canna tandilensis Ciciar. (Cannaceae-Zingiberales), a new species from Argentina.

Canna tandilensis is proposed as a species new to science. Plants grow wild terrestrial, in rocky places exposed to solar radiation forming dense colonies whose individuals of small to medium length, produce reduced inflorescences with large and few yellow to bright orange flowers and narrow and reflexed staminodes. The specific epithet refers to the city of Tandil at the south of Buenos Aires Province where the holotype comes from. It is related to other species having reduced inflorescences, narrow leaves and staminodes, and nectar guides in androecium pieces such as C. lineata. A detailed description of the new species is given, along with a study of the morphological vegetative and floral characters. These characters were compared with those from two other species C. glauca and C. lineata. According to these new evidences two groups of similar species of the genus are suggested. The number of species surveyed until now in Argentina rises to sixteen.

A couple of embroiled sheets of Miguel Barnades Manaider and Esteban de Prado in the Herbaria of Real Colegio Alfonso XII of San Lorenzo de El Escorial (Madrid)

In this paper we present a couple of sheets of Umbelliferae that are preserved in the RCAXII herbaria. One of them, Selinum carvifolia, where collected in the Gredos Mountains by Miguel Barnades Mainader and was identified by his son Miguel Barnades Clarís. The other, Tragium flabellifolium, was collected in Mieres (Asturias) by Esteban de Prado and identified by Mariano La Gasca.

Aproximación a la biogeografía del sector Setabense (provincia Catalano-Valenciano-Provenzal)

Se realiza una propuesta de división en subsectores del sector Setabense (Provincia biogeográfica Catalano- Valenciano-Provenzal). Las unidades reconocidas son: 1 subsector Valenciano;2 subseetor Enguerina-Cofrentino; 3 subsector Ayorano-Villenense; 4 subsector Alcoyano-Diánico. Para cada uno de ellos se aporta una breve descripción y caracterización de su flora, vegetación, paisaje vegetal, suelos, bioclimatología, usos del territorio, etc. Además se proponen dos nuevas combinaciones taxonómicas: Asperula paui Font Quer subsp. dianensis (Font Quer) de la Torre, Alcaraz & Crespo y Linaria depauperata Leresehe ex Lange subsp. hegelmaieri (Lange) de la Torre, Alcaraz & Crespo, y se valida la combinación Arctostaphyllos uva-ursi (L.) Sprengel subsp. crassifol¡a (Br.-Bl.) Rivas-Martínez ex de la Torre, Alcaraz & Crespo.

Datos sobre la vegetación del subsector Aljíbico (provincia Gaditano-Onubo-Algarviense)

Se estudian las principales cornunidades que constituyen el paisaje vegetal del subsector Aljíbico, describiendo dos nuevas asociaciones: Equiseto-Salicetum pedicellatae y Caricetum mauritanicae. Se proponen asimismo diversas subasociaciones en otras comunidades descritas anter¡ormente.

Datos sobre la vegetación del valle del río Bidasoa (España)

Se hace una descripción de las cinco series de vegetación que constituyen el paisaje vegetal de la cuenca del rio Bidasoa en Navarra (norte de España) y se aportan tablas fitosocíologicas de las comunidades que representan la etapa madura de cada serie asi como una tabla de los brezale sdel territorio. Se describen en ellas dos nuevas subasociaciones Polytricho setiferi-Fraxinetum excelsioris carpinetosum betuli y Tamo communis-Quercetum roboris fagetosum sylvticae.

Ecología y fitosociologia del ecótono de dos jarales de Cistion laurilfolii de la Sierra de Guadarranma (España)

Se describe la subasociación Rosmarino-Cistetum ladaniferi cistetosum cyprii. que representa el ecótono entre Rosmarino-Cistetum ladaniferi y Santolino-Cistetum laurifolii. La ecología del nuevo sintaxon se ha estudiado seleccionando dos grupos de parcelas que comprenden representantes de las tres unidades fítosociológicas, y sobre las que se han efectuado medidas de temperatura y humedad edáficas bajo la cubierta vegetal a lo largo del año, así como de distintos aspectos microclimáticos a lo largo de un día tipo. El carácter de transición de la nueva subasociación ha quedado puesto de manifiesto tanto para el factor térmico como hídrico.

Brassica oleracea L. distribution and ecology in the Iberian atlantic coasts

The distribution and ecology of Brassica oleracea in the atlantic coasts of Iberian Peninsule are studied. A new association or nitrified maritime cliffs is described: Crithmo-Brassicetum oleraceae. This community has been included in the Alliance Crithmo-Armerion due to the high presence of halophitic species.

11. La homonimia de Carici sylvaticae-Fagetum

El nombre Carici sylvaticae-Fagetum (sylvaticae) (Rivas-Martínez 1965) C. Navarro 1982 [Contribución al estudio de la flora y la vegetación del Duranguesado y la Busturia (Vizcaya): 81-82. Ed. Univ. Complutense, Madrid] fue propuesto para designar los hayedos basófilos de territorios orocantábricos y cántabro-euskaldunes, en sustitución del ilegítimo (Art. 34) Melico (uniflorae)-Fagetum cantabricum Rivas-Martínez 1965 [Anales Inst. Bot. Cavanilles 22: 383].
