Topics covered include their economic value, phylogenetic relationships, fossil history, cultivation, anatomy (by J.C. French) and chemistry (by R. Hegnauer).

The CVPRG is generated automatically from the Guinea Collections Database and the Guinea Names Backbone Database, both developed and maintained at the Royal Botanic Gardens, Kew, in collaboration with the staff of the National Herbarium of Guinea. A total of 3505 indigenous vascular plant species are reported of which 3328 are flowering plants (angiosperms); this represents a 26% increase in known indigenous angiosperms since the last floristic overview. Intended as a reference for scientists documenting the diversity and distribution of the Guinea flora, the CVPRG will a...

A subseção caracteriza-se pela lâmina foliar de consistência membranácea a cartácea, esverdeada discolor, com nervuras secundárias geralmente impressas adaxialmente e proeminentes abaxialmente em diversos graus, são geralmente ombrófilas e esciófilas. Registros inéditos de morfologia vegetativa e reprodutiva estão sendo apresentados, especialmente em relação às bagas (A. acutum, A. urvilleanum, A. hoehnei, A. ianthinopodum, A. loefgrenii, A. longicuspidatum, A. luschnathianum, A. marense e A. mourae). Apresenta-se uma chave para identificação das espécies, descrições detalhadas, comentários sobre a distribuição geográfica, ecologia, fenologia, conservação e ilustrações para cada uma delas.

Emphasis is given to his collecting localities in November 1906 in the campo rupestre of the Serra do Sincorá, Chapada Diamantina, where he collected type specimens of species from many genera and families. The available information suggests that his collections were made over a wide area along the western side of the Serra, from Camulengo in the south to near Mucugê in the north. Among them is one of the syntypes of Anthurium petrophilum (Araceae), recently re-discovered at the Herbarium Hamburgense (HBG). Ule also collected the other syntype in September 1906 at Maracás, a distinct inselberg highland to the east. Since recent morphological and molecular studies have shown populations from the two areas to be taxonomically distinct, the duplicate at the Berlin Botanical Mus...

The new collection is from the Brazilian state of Mato Grosso. Examination of the new inflorescence specimen confirms the accuracy of N. E. Brown's original description. A new description of the pollen is given.

The study focused on populations in isolated montane humid (brejo) forests of Ceará state in Northeast Brazil and compared them with populations from Amazonia and the Brazilian Atlantic Forest. Digitised outlines were prepared from a total of
