Antiprotozoal potential of Vismia species (Hypericaceae), medicinal plants used to fight cutaneous leishmaniasis.

Ethnopharmacological Relevance: Species of Vismia (Hypericaceae), known in Brazil as "lacre", are commonly used in traditional Amazonian medicine for the treatment of skin lesions, including those caused by Leishmania infection.

Aim Of The Study: Hexane extracts from the leaves of Vismia cayennensis, V. gracilis, V.

Deciphering the species complex (Malpighiaceae).

We describe three new species of Malpighiaceae that are endemic to central Brazil and related to the complex, a group of xylopodiferous, unbranched subshrubs with fruit in mericarps that have a strongly reduced or no dorsal wing. is more common in eastern Tocantins State and on the border with Bahia State, and there are a few records from Mato Grosso State. is restricted to northern Goiás State and has a wider distribution, occurring in some municipalities in northern Goiás and southern Tocantins.

The ethnobotanical relevance of the tribe Symphonieae (Clusiaceae) around the world.

Ethnopharmacological Relevance: The tribe Symphonieae (Clusiaceae) encompasses 48 species accommodated in seven genera (Lorostemon, Montrouziera, Moronobea, Pentadesma, Platonia, Symphonia and Thysanostemon). Parts of these plants, mainly the exudates and the seeds oil are useful for different purposes, especially for treating dermatological conditions. In addition to the role in the folk medicine, some species are of great economic and cultural importance for native people from different continents.

Clarifying the nomenclatural history of , a Brazilian endemic genus of Clusiaceae.

Planch. & Triana is a Brazilian Atlantic Forest endemic genus composed of two species: (Spreng.) Planch.

How phantom databases could contribute to conservation assessments.

Reliable data are needed to produce representative and useful conservation assessments for species. To this end, taxonomists and their unpublished, archived and unused databases-here called phantom databases-have great relevance for assessing the conservation status of species. Taxonomist's phantom databases are usually the result of a review work, and, if made available, they could be used to assess a species conservation status with greater accuracy, allowing for more effective conservation planning.

Plastomes resolve generic limits within tribe Clusieae (Clusiaceae) and reveal the new genus Arawakia.

Clusieae is an exclusively Neotropical tribe in the family Clusiaceae sensu stricto. Although tribes within Clusiaceae are morphologically and phylogenetically well-delimited, resolution among genera within these tribes remains elusive. The tribe Clusieae includes an estimated ∼500 species distributed among five genera: Chrysochlamys, Clusia, Dystovomita, Tovomita, and Tovomitopsis.
