Fragmentos Taxonómicos, corológicos, nomenclaturales y fitocenológicos

Se relacionan 75 táxones recolectados dentro de los límites del sector Rondeño (provincia Bética) y que se encuentran poco citados o que suponen novedad. Para cada uno de ellos se indican las localidades (incluyendo la cuadrícula UTM de 1 km2 ), ecología observada y altitud. Los testigos se encuentran depositados en el Herbario del Departamento de Botánica de la Facultad de Farmacia de Sevilla (SEVF).A list of 75 scarcely recorded or wich mean new records taxa from the sector Rondeño (Betica province) is given. Localities (including UTM squares 1 km 2 ), ecology and altitude are also given. All the sheets are conserved in the Herbarium of the Departament of Botany, Faculty of Farmacy, Seville (SEVF)

Karyological studies in Hieracium baeticum (Asteraceae) from the "Parque Natural de la Sierra de Grazalema" (Southern Spain)

Hieracium baeticum is a triploid (2n = 27) species restricted to Iimestone mountains in Sand E Spain. 80th developing capitula and root tips from seedlings were used for the study. The karyotype suggests an allopolyploid ori gin of the taxon, and a relative close affinity between its parental is indicated by the possibility of partial pairing of most chromosomes during microsporogenesis. This process is completely disturbed starting from the first phases to degenerative pollen forrnation: none is forrned or shed. In more than 60 % of the f1owers, some kind of synapsis occurs in pollen mother cells, while there is total univalence in the rest. The species is considered strictly agamosperrnous in ali the studied populations
