Dos especies nuevas de Borreria (Rubiaceae), sinopsis y clave de las especies para Bahia, Brasil

This work deals with a taxonomic study of the genus Borreria (Rubiaceae) for the state of Bahia, 29 species are recorded. Most of these species are distributed in the cerrado and Atlantic forest biomes. Two new species are described and illustrated, Borreria catolensis E.L. Cabral & L.M. Miguel and Borreria diamantinae R.M. Salas & E.L. Cabral. Th e new combination Borreria schumannii (Standl. ex Bacigalupo) E.L. Cabral & Sobrado is proposed. Neotype is designated for B. virgata. Epitype is designated for B. scabiosoides and lectotypes are designated for B. eryngioides and B. humifusa. A key for identification, comments on geographic distribution and habitats are provided, maps and a table with the species distribution for biomes are also included. Borreria crispata, B. cupularis, B. humifusa, B. virgata and B. wunschmannii are illustrated for the first time. The identities of B. ocymoides and B. prostrata are discussed; the fi rst species is also illustrated. Borreria virgata and B. spinosa are reinstated. Two figures with representative photographs of 20 species are included.

Revisão de Mitracarpus (Rubiaceae - Spermacoceae) para o Brasil

This paper presents the revision of Mitracarpus from Brazil. The study is based on field observations and study of herbarium specimens. Mitracarpus is a neotropical genus, distributed from the southern United States to central Argentina, with one invasive species occurring in the Old World. The genus presents three centres of diversity: Mexico, the Caribbean region and Brazil. Twenty four species are accepted, of which six are new to science: Mitracarpus albomarginatus, M. buiquensis, M. diversifolius, M. eitenii, M. nitidus and M. robustus. A key to identify the species, updating of the names and their typification, synonymy, descriptions, illustrations are provided, together with data on their conservation status.

Revisión Sinóptica de Galianthe Subgen. Galianthe (Rubiaceae: Spermacoceae), con una Sección Nueva1,2

Abstract Galianthe subg. Galianthe Griseb. se caracteriza por el fruto de mericarpios dehiscentes, semillas rollizas o complanadas con bordes aliformes, inflorescencias generalmente amplias tirsoides o pleiotirsoides, flores heterostilas, hábito erecto generalmente con xilopodio y cromosomas x = 8. Está representada por 39 especies sudaméricanas que se agrupan en dos secciones: sect. Galianthe (30 especies) y una nueva sect. Laxae E. L. Cabral (nueve especies y dos subespecies). Se acompañan claves para diferenciar las secciones y las especies de cada sección, con resumen sinóptico de las especies y mapas de distribución. Se designan neotipos para cuatro nombres: Borreria angustifolia Cham. & Schltdl. [= G. angustifolia (Cham. & Schltdl.) E. L. Cabral], B. equisetoides Cham. & Schltdl.

Borreria krapocarmeniana, a New Cryptic Species Recovered Through Taxonomic Analyses of Borreria scabiosoides and Borreria linoides (Spermacoceae, Rubiaceae)

Abstract The new species Borreria krapocarmeniana (Rubiaceae) is described and illustrated. The taxonomic identity of Borreria linoides and Borreria scabiosoides are discussed. Borreria organensis and Borreria rubricaulis are proposed as new synonyms of B. scabiosoides. Seed micromorphology and pollen grains of the three species are analyzed and a map with the distribution of these species is presented. Additionally, a table featuring diagnostic characters to distinguish between species is provided.

Two New Species of Borreria (Rubiaceae) from Brazil, with New Distributional Records for Pará State and a Key to Species with Transversally Sulcate Seeds

Two new species of the genus Borreria, B. carajasensis E.L. Cabral & L.M. Miguel and B. elaiosulcata E.L. Cabral & L.M. Miguel, are described and illustrated, based on material collected from iron outcrops in the Serra dos Carajás region, Pará State, Brazil. A key to morphologically similar species is provided; these species can be recognized by their transversally sulcate seeds. Borreria cupularis and B. multiflora are reported for the first time from the Pará State.

Dos nuevas especies de Staelia (Rubiaceae) con hojas ternadas del nordeste de Brasil
