The Serra Dourada State Park - SDSP is the second largest Park in the Goiás state, covering 30,000 hectares. Aiming to understand the diversity of Asteraceae in Goiás we did the taxonomic treatment of Eupatorieae from this Park. The Eupatorieae is represented in SDSP by 12 genera and 23 species. Chromolaena and Mikania are the genera with the large...

ABSTRACT Lessingianthus spinifolius is here described and illustrated as a new species of the tribe Vernonieae (Asteraceae) from Chapada dos Veadeiros, State of Goiás, Brazil. The new species is thus far known only from the type locality. The characteristics that most differentiate L. spinifolius from congeners are: (i) leaf blade strongly revolute...

In this paper, we describe a new species of Praxelis from Goiás, present a key and comments on the Brazilian species of Praxelis with a special note on the status of P. grandiflora. Additionally, the synonymy of P. macrocarpa under P. capillaris is proposed.

The South American genus Praxelis Cass. (Asteraceae, Eupatorieae) includes 18 species and is the second-largest genus of subtribe Praxelinae. It is distributed from Colombia, Venezuela and the Guianas, to central Argentina, southern Brazil and north-western Uruguay. Over the past 40years, one species, P. clematidea , has invaded several countries a...

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...

El género Praxelis Cass. habita zonas templadocálidas de Sudamérica. Se distingue por sus filarias caducas, receptáculo cónico y carpopodio asimétrico. La delimitación de especies es poco clara debido a la superposición de caracteres y a distintas interpretaciones y terminologías utilizadas para definirlos. El objetivo del trabajo es actualizar su...

The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...

The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease the loss of plant diversity, reduce poverty and contribute to sustainable development. To achieve this overarching goal, the GSPC has established a series of targets, one of which is to ensure that plant diversity is well understood, s...
