In this study, we present and discuss the recognition of Garcinia madruno as a species complex. The taxonomic limits of G. madruno are discussed with the related species, and the names and type collections of the respective synonyms were analyzed. Based on morphological data, three new species (Garcinia ieda-amaralae Mouzinho & M.L.Soares, G. gutti...

Garcinia leptophylla Bittrich, a species known only in Bolivia and Brazil, has an extended geographic distribution to Colombia and Peru. In addition, we present a detailed description of the pistillate flowers , a distribution map, a comparison with similar species, and for the first time, photos of the species in vivo.

Este estudo fornece informações sobre germinação de sementes e morfologia de plântulas de Philodendron Schott, da Amazônia Central. Testes de germinação foram realizados com 4x50 sementes em papel de germinação a 25°C com 12 horas de luz ou no escuro. As infrutescências de Philodendron eram compostas por bagas com ca. 7–71 sementes/fruto. As sement...

Philodendron josephii sp. nov. is described from terra firme tropical humid forest in Amazonas state, Brazil. This new species is similar in its leaf morphology to two other Amazonian species, P. maximum and P. megalophyllum, but differs by characters of the prophyll, petiole, flagelliform branches and ovary. The description is accompanied by illus...

While studying specimens of Garcinia gardneriana from the Brazilian Amazon we detected problems in reconciling the morphology of these collections to that of the type collection (with the basionym of Rheedia gardneriana) and similar specimens from other regions of Brazil. An investigation led us to the conclusion that the Amazonian collections repr...

Philodendron rio-pretense C.A.S.Bat. & M.L.Soares belongs to the subgenus Philodendron. This newly described species is similar to P. carinatum and P. wurdackii but differs from these species primarily due to a combination of the following characteristics: persistence of the prophyll (twisted); stipe short, locules 4 – 7, ovules 1 – 2 and funiculus...

The binomial Rheedia spruceana Engl. has been considered a synonym of Garcinia gardneriana (Planch. & Triana) Zappi. When analyzing the type collections of both names, we detected the need to restored R. spruceana with a new combination in Garcinia. This new combination is herein proposed. We also clarify the inadvertent lectotype selection for R....

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 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...

Philodendron (Araceae) is one of the largest Neotropical plant genera, with approximately 500 species and at least 1000 species predicted. There is a considerable ecological diversity in the group, although most species occur in the humid forests of tropical America. Despite being relatively well-studied in taxonomic analyses, the relationships amo...

A new species of Philodendron in central Amazonia, Manaus-AM, Brazil, is described and illustrated. Philodendron melloi belongs to the subgenus Philodendron and is possibly a representative of the section Tritomophyllum. This newly described species is similar to P. barrosoanum and P. hyleae, but differs Its preference for terrestrial habitats, per...

Philodendron is the second most diverse genus of the Araceae, a tropical monocot family with significant morphological diversity along its wide geographic distribution in the Neotropics. Although evolutionary studies of Philodendron were conducted in recent years, the phylogenetic relationship among its species remains unclear. Additionally, analys...

An updated inventory of Brazilian seed plants is presented and offers important insights into the country’s biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, sh...

The genus Philodendron is a highly diverse Neotropical group of the monocot family Araceae. Despite chromosome counts being relatively abundant for the family, information on the karyotype evolution within the genus is still scarce and very confusing. Therefore, we report diploid numbers and additional cytological features for 43 species of Philode...

Abstract— A preliminary taxonomic revision is presented of the Neotropical genus Heteropsis, widely known as the source of a regionally important non-timber forest product; a tough resistant root fiber used in craftware and furniture making. Eighteen species and one variety are recognized, including two new species, Heteropsis reticulata and Hete...

In the Amazon region of Brazil, the roots of different species of Philodendron are used in the traditional medicine. Philodendron fragrantissimum (Hook.) G. Don, locally known as ‘cipó-tracuá’, has very aromatic roots and is used for baths and fumigation. Here, we describe the chemical composition of the essential oil from the roots of P. fragranti...

As especies hemiepifitas do genero Heteropsis produzem raizes aereas que sao conhecidas na Amazonia brasileira como cipo-titica e titicao ou cipo timbo-acu, sendo fonte produtora de fibra de alto valor comercial, principalmente na fabricacao de artesanatos e moveis. Essa materia-prima e intensamente explorada de forma insustentavel, tendo grande re...

A pilot study of leaf outline morphometrics was carried out on populations of five species of Heteropsis located in the Reserva Florestal Adolpho Ducke near Manaus, Amazonas, Brazil: H. flexuosa (Kunth) G. S. Bunting, H. macrophylla A. C. Sm., H. spruceana Schott, H. steyermarkii G. S. Bunting and H. tenuispadix G. S. Bunting. The aim of the study...

to investigate quantitative methods for discriminating species within a local area based on veget-ative morphology in a genus where fertile parts are often difficult to find in the field; this study focussed on leaf outline shape. Using digital images of 347 leaves, outlines were captured as coordinates using the TpsDig software and analysed using...

The species of the genus Heteropsis, known throughout Brazilian Amazonia as “cipó-titica”, have long been the target of intensive commercial collection because of the valuable fibre which is made from their aerial roots. The fibre is widely used in regional craft manufacture and forms part of the extractive industry of the region, based on forest p...
