“…Thus, floras span a wide range of land areas, from 1 ha or less to many millions of hectares. (p. 24) Floras range from government documents, theses, unpublished reports, online Web sites, short notes and lists in botany journals to 2,000-page books with thousands of references (Palmer, Wade, & Neal, 1995). McLaughlin (2007), another phytogeographer, adds that most floras usually comprise between 200 and 1,000 species and are focused on "local intact remnants of the regional flora in areas of intense agricultural and urban development" (p. 2).…”

To determine influences on the production of a scientific article, the content of the article must be studied. We examined articles in biogeography and found that most of the influence is not cited, specific types of articles that are influential are cited while other types of that also are influential are not cited, and work that is "uncited" and "seldom cited" is used extensively. As a result, evaluative citation analysis should take uncited work into account.

“…A well--produced flora constitutes a fundamental tool for research in many disciplines, such as ecology, biogeography, evolution and ethnobotany (Mori 1992;Funk 2006;Palmer et al 1995), and provides a major source of information for conservation, land-use planning and sustainable use of ecosystems (Mori 1992;Palmer et al 1995;Prance et al 2000). "Taxonomic impediment" is the critical lack of taxonomic knowledge, and has been considered a major obstacle for conservation and sustainable use of biodiversity (Schnak & López 2003;Crisci 2006;Funk 2006).…”

RESUMO(Flora lenhosa do Uruguai: inventário e implicação na região Pampeana). Contar com um conhecimento adequado da flora é fundamental para o desenvolvimento de investigação em diversos campos disciplinares. Neste contexto, nosso trabalho surge da necessidade de atualizar e melhorar a informação disponível sobre a flora lenhosa nativa do Uruguai. Nossos objetivos são determinar objetivamente a flora lenhosa uruguaia (arbustos e árvores), avaliar a completude do inventário e explorar sua similaridade com regiões vizinhas. Ao analisar a flora do Uruguai, produzimos definições operacionais de arbustos e árvores e obtivemos uma lista de 313 espécies (57 famílias, 124 gêneros). Usando 7.418 registros de distribuição, geramos curvas acumulativas de riqueza de espécies para estimar o potencial máximo de riqueza de espécies em escala nacional e local. Concluímos que a completude a nível nacional é elevado (89-95%), mas em escala local é menor e bastante heterogêneo. Existem ainda grandes áreas sem dados ou com pouca informação. Encontramos que as espécies arbóreas do Uruguai, comparativamente, apresentam similaridade elevada com a Província de Entre Rios (Argentina), média com a Província de Buenos Aires (Argentina) e baixa com o Rio Grande do Sul (Brasil). Conclui-se que a riqueza de árvores e arbustos da flora uruguaia é maior do que a esperada para uma região de pradarias, e as diferenças encontradas nos indíces de similaridade com as floras lenhosas vizinhas estimulam estudos futuros para reavaliar o esquema fitogeográfico da região. Palavras chave: Distribuição geográfica; Completude do inventário; Arbustos e árvores; Fitogeografia do Uruguai ABSTRACT(Woody flora of Uruguay: inventory and implication within the Pampean region). Adequate knowledge of a flora is fundamental for furthering research in several disciplines. In this context, our work arises from the necessity to update and improve available information on the native woody flora of Uruguay. The goals of this study were to objectively determine the Uruguayan native woody flora (shrub and trees), to evaluate its inventory completeness, and to explore its similarity with neighboring regions. By analyzing the Uruguayan flora we produced working definitions of shrubs and trees, and obtained a list of 313 species (57 families, 125 genera). Using 7418 distribution records, we generated cumulative species richness curves to estimate maximum species richness at national and local scales. We conclude that the completeness at the national level is high (89-95%), but at the local scale is lower and quite heterogeneous. There are still large areas without data or with little information. We found that comparatively, the similarity between Uruguayan tree species and the Province of Entre Ríos (Argentina) was high, while similarity with the Province of Buenos Aires (Argentina) was medium, and with Rio Grande do Sul (Brazil) was low. In conclusion, richness of tree and shrub species of the Uruguayan flora is greater than expected for a grassland region, and the differe...

“…Los muestreos se realizaron en forma aleatoria y cualitativa, y la recolección de ejemplares se ajustó a los estándares de inventarios florísticos y de preservación de las muestras (véanse Johnston, 1941;Lot & Chiang, 1986;Bridson & Forman, 1992;Gould & Shaw,1992;Palmer, et al, 1995). Las colecciones realizadas se depositaron en el Herbario Nacional Colombiano (COL), con duplicados en varios herbarios nacionales (CAUP, COAH, HUA, LLANOS, entre otros).…”

Axonopus es un género nativo del continente americano del cual se conocen unas 71 especies, principalmente concentradas en el norte de Sudamérica, con algunos representantes aparentemente introducidos en el Viejo Mundo. Se presenta el estudio morfológico y taxonómico de las especies colombianas, sus sinónimos, su descripción e iconografía, su distribución geográfica y ecológica, sus nombres vernáculos, sus usos, y se comentan algunas particularidades morfológicas, así como las relaciones morfológicas de las especies. Se discuten las afinidades morfológicas y filogenéticas con Digitaria, Mesosetum, Paspalum, Spheneria y Streptostachys. Se propone un nuevo nombre para Axonopus sect. Cabrera. Dos binomios se reducen a la sinonimia Axonopus piccae (
