This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the num...

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, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lian...

Phytotaxa

A taxonomic revision of the Rudgea hostmanniana complex in the Guiana shield region is presented.... more A taxonomic revision of the Rudgea hostmanniana complex in the Guiana shield region is presented. This group includes species with sheathing stipules bearing dorsal appendages, thick glabrous leaves lacking domatia, inflorescences thyrsoid to glomerulate but not regularly dichotomous, a calyx tube absent or very short, a corolla tube 2–7(–13) mm long, and fruits usually brownish when immature and turning red or orange at maturity. Eight species are recognized, among which Rudgea billietiae, endemic to Kaw Mountain in French Guiana, is newly described and illustrated; it is assessed as Endangered according to IUCN criteria. The other species are R. bolivarensis, R. cornigera, R. coussareoides, R. hostmanniana, R. maypurensis, R. pungens, and R. tanaosepala. A key to the species is presented, as well as a table summarising their diagnostic characters.

While revising the material for the Flora of the Guianas, the authors uncovered and hereby describe six new species: R. approuaguensis, R. glomerulata, R. graniticola, R. itoupensis, R. jadinii and R. leucocarpa. Most of these are endemic to French Guiana, except R. graniticola which also occurs in Suriname, and R. leucocarpa, recorded also from Suriname and northern Brazil. Additionally, the original description of Rudgea ayangannensis, endemic of Guyana, is emended as it was based on a mixture of two different species, and adjustments are provided in a new description.

Rudgea minutifolia Bruniera & Torres-Leite is distinguished by its small leaves, a character found in only a handful of species in this genus. The indumentum of the branches, leaves and stipules, low number of secondary veins, corniculate corolla lobes, and vinaceous to almost black mature fruits are also characteristic of this species. Discovered in a forest remnant within the Atlantic Rainforest domain in the south of Espírito Santo state, this species is found only in the municipality of Castelo, an area that has been recognized as prioritary for conservation. Besides the description, taxonomic comments, conservation status, images and illustrations are provided.

Their characters agree with Palicourea s.l., and these two species are here transferred to this latter genus. P. parajusticioides C. M. Taylor, Bruniera & Zappi is based on R. justicioides Standl., of the western Amazonian basin in Peru; and P. woronovii (Standl.) Bruniera & C. M. Taylor is based on R. woronovii Standl., also from the western Amazonian basin of Peru. Meanwhile, several Neotropical shrubs and trees classified in Psychotria subg. Heteropsychotria Steyerm. share the characteristic triangular to truncate stipule form with caducous glandular appendages that indicate they belong to Rudgea, and they are transferred here: R. coussareoides (Standl.) C. M. Taylor, Bruniera & Zappi is based on Psychotria coussareoides Standl. from southern Venezuela, southern Guyana, and eastern Peru; R. pungens (Steyerm.) C. M. Taylor, Bruniera & Zappi is based on Psychotria pungens Steyerm. from French Guiana; R. rondeletioides (Standl.) C. M. Taylor, Bruniera & Zappi is based on Psychotria rondeletioides Standl., from Colombia; R. sanmartensis (Rusby) C. M. Taylor, Bruniera & Zappi is based on Psychotria sanmartensis Rusby of northern Colombia and Venezuela; R. venezuelensis (Steyerm.) C. M. Taylor, Bruniera & Zappi is based on Psychotria venezuelensis Steyerm., from southern Venezuela; and R. ventuariana (Standl. & Steyerm.) C. M. Taylor, Bruniera & Zappi is based on Psychotria ventuariana Standl. & Steyerm. of Cerro de la Neblina, on the southern border of Venezuela, and probably also occurs in Brazil.

Rudgea was previously characterized by the presence of usually terminal inflorescences, with pseudo-axillary inflorescences occurring in a single species, R. stipulacea. Rudgea quisquiliae is morphologically distinct within the genus by the combination of its large leaf-blades (15-33.5 × 7.5-15 cm), and axillary inflorescences. Rudgea axilliflora can be distinguished by its sheathing stipules with dorsal, glandular appendages, mediumsized leaf-blades (7-11 x 2.5-4 cm), lanceolate to elliptic, with 7-9 pairs of secondary veins, absence of domatia, axillary inflorescences and flowers with a distinctly lobed calyx. The new species were discovered in ombrophilous rainforest remnants in the south of Espírito Santo, one of the most diverse states in the Atlantic Forest biome.

Recent phylogenetic analyses support a recircumscription of Conchocarpus to accommodate the species of Almeidea, a taxon from the Brazilian Atlantic Rainforest and Bolivia whose synapomorphy is the possession of pantocolporate pollen grains. Four species are recognized here: C. albiflorus, C. coeruleus, C. hendrixii, and C. ruber. A taxonomic revision of this group of four species of Conchocarpus is provided, with updates of their nomenclature, morphology, circumscription, geographic distribution, and preliminary conservation status, as well as a key to the species and illustrations. Conchocarpus limae and C. lilacinus are consigned to the synonymy of C. ruber.

To date, this new species is known from populations observed in the municipalities of Cardoso Moreira and São Fidélis in Serra da Bandeira/Serra da Vista mountain ranges in northern Rio de Janeiro state in the Atlantic Rainforest biome and was brought to light as an undescribed species thanks to photographs shared on the social media site Facebook. The epithet “hendrixii” is in honor of Jimi Hendrix, guitarist and singer-songwriter, who wrote the song “Purple Haze,” in reference to the purple color of the flowers of the new species. Analyzes showed that flowers of the new species bear a staminal tube, a characteristic present only in C. odoratissimus among the Conchocarpus. However, this species bears flowers with much shorter staminal tubes (c. 2–2.5 mm in length v. 1–1.2 cm in the new species) and smaller flowers, among other morphologically dissimilar characteristics. Molecular phylo...

This new species, Almeidea albiflora, is known so far only from a few collections made in small disturbed forest remnants in the vicinity of Cachoeiro de Itapemirim, in the state of Espírito Santo, and by a single collection from northern Rio de Janeiro state, both in the domain of the Atlantic Forest, Eastern Brazil. Diagnostic features, like white petals, sericeous ovary and distal secondary axes as long as the proximal ones are identified. Pollen morphology is also described, and brief discussions of the relationships of the new taxon to other species of Almeidea, as well as comments on its conservation status, are provided.

The new species occur in the eastern Bahia State, Brazil, which is a place of high diversity for Rudgea. Rudgea agresteophila is morphologically distinct within the genus, by the combination of thickly coriaceous leaves, flowers with long calyx-tube and fruits crowned by a persistent calyx up to 6 mm long; and is known only from the type locality, in the municipality of Jequié. Rudgea hileiabaiana is distinguished by its coriaceous leaves, up to 30 cm long and round to cordate base, broadly infundibular corolla and unexpanded calyx; and it is restricted to southern Bahia. Detailed data on distribution and habitat, phenology and conservation status of both species are presented.

Research paper thumbnail of Almeidea A. St.-Hil. Belongs to Conchocarpus J.C. Mikan (Galipeinae, Rutaceae): Evidence from Morphological and Molecular Data, with a First Analysis of Subtribe Galipeinae

PLOS ONE, 2015

Subtribe Galipeinae (tribe Galipeeae, subfamily Rutoideae) is the most diverse group of Neotropic... more Subtribe Galipeinae (tribe Galipeeae, subfamily Rutoideae) is the most diverse group of Neotropical Rutaceae, with 28 genera and approximately 130 species. One of its genera is Almeidea, whose species are morphologically similar to those of the genus Conchocarpus. Species of Almeidea occur in the Atlantic Rain Forest of Eastern Brazil, with one species (Almeidea rubra) also present in Bolivia. The objective of this study was to perform a phylogenetic analysis of Almeidea, using a broader sampling of Galipeinae and other Neotropical Rutaceae, the first such study focused on this subtribe. To achieve this objective, morphological data and molecular data from the nuclear markers ITS-1 and ITS-2 and the plastid markers trnL-trnF and rps16 were obtained. Representatives of eight genera of Galipeinae and three genera of Pilocarpinae (included also in Galipeeae) and Hortia (closely related to Galipeeae) were used. Five species of Almeidea and seven of Conchocarpus were included, given the morphological proximity between these two genera. Individual (for each molecular marker) and combined phylogenetic analyses were made, using parsimony and Bayesian inference as optimization criteria. Results showed Galipeinae as monophyletic, with the species of Almeidea also monophyletic (supported by the presence of pantocolporate pollen) and nested in a clade with a group of species of Conchocarpus, a non-monophyletic group. Additionally, C. concinnus appeared in a group with Andreadoxa, Erythrochiton, and Neoraputia, other members of Galipeinae. As a result, Conchocarpus would be monophyletic only with the exclusion of a group of species related to C. concinnus and with the inclusion of all species of Almeidea with the group of species of Conchocarpus that includes its type species, C. macrophyllus. Thus, species of Almeidea are transferred to Conchocarpus, and the new combinations are made here.

Pollen morphology is also described, and brief discussions of the relationships of the new taxon to other species of Almeidea, as well as comments on its conservation status, are provided.

The new species occur in the eastern Bahia State, Brazil, which is a place of high diversity for Rudgea. Rudgea agresteophila is morphologically distinct within the genus, by the combination of thickly coriaceous leaves, flowers with long calyx-tube and fruits crowned by a persistent calyx up to 6 mm long; and is known only from the type locality, in the municipality of Jequié. Rudgea hileiabaiana is distinguished by its coriaceous leaves, up to 30 cm long and round to cordate base, broadly infundibular corolla and unexpanded calyx; and it is restricted to southern Bahia. Detailed data on distribution and habitat, phenology and conservation status of both species are presented.

Research paper thumbnail of Almeidea A. St.-Hil. Belongs to Conchocarpus J.C. Mikan (Galipeinae, Rutaceae): Evidence from Morphological and Molecular Data, with a First Analysis of Subtribe Galipeinae

PLOS ONE, 2015

One of its genera is Almeidea, whose species are morphologically similar to those of the genus Conchocarpus. Species of Almeidea occur in the Atlantic Rain Forest of Eastern Brazil, with one species (Almeidea rubra) also present in Bolivia. The objective of this study was to perform a phylogenetic analysis of Almeidea, using a broader sampling of Galipeinae and other Neotropical Rutaceae, the first such study focused on this subtribe. To achieve this objective, morphological data and molecular data from the nuclear markers ITS-1 and ITS-2 and the plastid markers trnL-trnF and rps16 were obtained. Representatives of eight genera of Galipeinae and three genera of Pilocarpinae (included also in Galipeeae) and Hortia (closely related to Galipeeae) were used. Five species of Almeidea and seven of Conchocarpus were included, given the morphological proximity between these two genera. Individual (for each molecular marker) and combined phylogenetic analyses were made, using parsimony and Bayesian inference as optimization criteria. Results showed Galipeinae as monophyletic, with the species of Almeidea also monophyletic (supported by the presence of pantocolporate pollen) and nested in a clade with a group of species of Conchocarpus, a non-monophyletic group. Additionally, C. concinnus appeared in a group with Andreadoxa, Erythrochiton, and Neoraputia, other members of Galipeinae. As a result, Conchocarpus would be monophyletic only with the exclusion of a group of species related to C. concinnus and with the inclusion of all species of Almeidea with the group of species of Conchocarpus that includes its type species, C. macrophyllus. Thus, species of Almeidea are transferred to Conchocarpus, and the new combinations are made here.
