Article
Full-text available
The Botanical Society of Brazil (SBB) for many years discussed the need to improve the nation’s herbarium collections, by providing training and educating botanists as specialists in plant and fungal taxonomy. It was in this context that an audacious project was developed, which envisaged personnel training for studies in plant and fungal diversity...
Article
A taxonomic revision of the species currently circumscribed in Tarenaya Raf. (Cleomaceae) is presented here. Tarenaya comprises 38 species distributed from Mexico to Argentina (except for Chile) and the West Indies, and with one species disjunct in Central Africa. We present a new combination, 14 lectotypifications, and two neotypifications, and de...

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...

The name Cleome heptaphylla was published by Linnaeus in the second edition of Species plantarum and is still untypified. Analysis of the protologue and the associated pre‐Linnaean names indicated the absence of original material that could serve for lectotypification. A specimen from Miller’s herbarium at BM is designated as its neotype. The neoty...

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...

Chiococca insularis (Ridley) C.M.Taylor & M.R.V.Barbosa (Rubiaceae) was described by Henry Nicholas Ridley in 1890, based on a collection he made on the island of Fernando de Noronha (Pernambuco, Brazil) in 1887. Since then, this species had not been collected again and has been treated as probably extinct. After 130 years, we discovered two new po...

The family Cleomaceae is represented in the Neotropics by nine native lineages, with some of them currently recognized as distinct genera and others in need of clear delimitation. We present here a new phylogenetic hypothesis for the New World Cleomaceae with a more comprehensive sampling, including samples of 62 species with emphasis on Tarenaya a...

In tropical dry areas, rainfall is predicted to be the most important climatic variable influencing bird phenology because it triggers food and foliage production. In addition, because resources are scarce, the moulting and breeding seasons are not expected to overlap. We conducted a 2-year study on the phenology of passerine birds at one site in C...
