This tribe has its center of diversity on the Guiana Shield (northern South America), where 9 of the 10 genera occur. Only Sipanea and Limnosipanea are also present on the Brazilian Shield and the Orinoquía Region with a total of 4 species, while Steyermarkia, Sipanea and Limnosipanea are present in Central America with one species each. The genera Sipaneopsis, Chalepophyllum, and Dendrosipanea are endemic to white sand areas of the Amazon Basin. The habit in the tribe Sipaneeae ranges from herbs (terrestrial, amphibian or rarely aquatic), subshrubs, shrubs to treelets. Within the tribe, Chalepophyllum, Dendrosipanea, Neobertiera, Pteridocalyx and Sipanea are heter...

Berg (1857: 287) treated E. rotundifolia Casaretto as a distinct species, and recognized two varieties. However, the binomial E. rotundifolia (Walker-Arnott 1836: 335) Wight (1841: 17) was previously published for a taxon occurring in Sri Lanka. Therefore, Casaretto’s name is a later superfluous homonym and illegitimate. In a recent article on the typification of plant names published by Casaretto, Delprete et al. (2019) proposed E. casarettoana Delprete (2019: 25) as a substitute name for E. rotundifolia Casaretto. However, Delprete and his collaborators overlooked that the name E. casarettoana O. Berg (1857: 520) was previously published using material collected by Martius near the town of Coari, state of Amazonas, Brazil, and belongs to a distinct species occurring in the Brazilian A...

Twelve years later, Allemão and Saldanha described Pinckneya rubescens and P. viridiflora, also from material collected in Rio de Janeiro; the holotypes of these two Pinckneya names have recently been found in the Herbarium of the National Museum of Rio de Janeiro. After comparative studies of their types and recent collections, we concluded that these taxa are synonymous with Simira alba (Mart.) comb. nov. and Simira rubra. Comments on typification and critical historical collections of all taxa involved are also provided.

Research paper thumbnail of Additional studies in Neobertiera (Rubiaceae, Sipaneeae): a new species from the state of Pará, Brazilian Amazon, and a new combination for a species from French Guiana

In the present paper, a new species, N. montedouradensis, from the state of Pará, Amazon Basin, is described, which represents a significant range extension and the first record of this genus for Brazil. This new species is unique within the genus by having hypanthia and fruits with trichomes conspicuously tuberculate at base. In addition, a new combination is proposed for a species from French Guiana recently named N. glomerata. A correction regarding the corolla size of N. pakaraimensis is included. In view of these taxonomic novelties, a key to the five species of Neobertiera is provided.

The second part is focused on Pteridocalyx, the sole genus of the tribe Sipaneeae with calycophylls, until recently only known by three historic collections (including two type gatherings) from Guyana. Recent field observations and collection of numerous herbarium specimens permitted a detailed study of this genus, which is here reported for the first time to have distylous flowers. Two species were described in the genus. As a result of a detailed morphological analysis, Pteridocalyx is here treated as monospecific, and is here illustrated for the first time.

Alkaloid 2 inhibited malate synthase from the pathogenic fungus Paracoccidioides spp. This enzyme is considered an important molecular target because it is not found in humans. Molecular docking simulations were used to describe the interactions between the alkaloids and malate synthase

Borhidi cultivated in French Guiana. This essential oil was examined by a combination of GC/FID and GC-MS techniques and was further tested for antifungal activity against several Candida strains, as well as for anti-leishmanial activity against the reference strain Leishmania guyanensis. A total of 45 components accounting for 93.61% of the total GC/FID chromatogram were identified. The essential oil is dominated by sesquiterpenes and oxygenated sesquiterpenes among which β-caryophyllene (46.99 ± 0.32%) is the major one. No anti-leishmania activity could be assessed, while a strong antimicrobial activity of this essential oil was evidenced in vitro against a Candida albicans strain by the definition of a MIC value of 250 μg/mL. V. schomburgkii essential oil might hence be considered in the future for the development of natural antifungal agents.

It most resembles S. grazielae, from which it differs by the larger inflorescences, antrorse pubescent flowers and fruits, and by its larger fruits. Its habitat and conservation status are discussed. A key to the species of Simira from Espírito Santo state is provided.

Values of plumericin concentration from leaves were obtained by High-Performance Liquid Chromatography, and evaluated as a function of differences in soil types, variation of precipitation, and variation of the abundance of insect herbivores, using first a Repeated Measures Correlation (rmcorr) and then a Generalized Linear Mixed Model (GLMM) analysis. Plumericin concentration is highly variable among plants, but with a significantly higher concentration in plants growing on clay soil compared to that of the white-sand soil habitat (p < 0.001). Plumericin concentration is not affected by precipitation. The caterpillar of Isognathus leachii (Lepidoptera: Sphingidae) is the most conspicuous herbivore of ...

While in Hawaii, he developed a par-ticular interest for the Pacific islands flora and for ethnobotany, two passions that he pursued for the rest of his life.

The interviews were conducted to determine the uses of these plants in different regions of the country. The most frequent uses of species of the genus Dioscorea in Cuba are dietary supplement, against gastric affections (gastritis) and in Yoruba religious rituals. Values of use of the useful species of the genus were determined. Some ecological aspect as well as the distribution of the species were analysed.

Therefore the Chilean specimens are treated as a narrowly endemic, separate species, Ombrophytum chilensis Kuijt & Delprete, on the basis of the type specimen and published photographs. Discussions on morphology, distribution and conservation status are provided for this species. Critical comments on the underground organs and reproduction in Neotropical Balanophoraceae are also presented.

In order to recognize and clarify the species of Himatanthus occurring in Peru, herbarium specimens were examined, coupled with detailed field observations. The present study recognizes three species in Peru: H. revolutus, H. tarapotensis and H. phagedaenicus. A key to identify the species, as well as descriptions, synonymy, specimens cited, and taxonomic comments are presented.

After collecting in a few localities in southern Brazil and Uruguay, Casaretto collected for almost nine months, from April to December 1839, in Rio de Janeiro and its vicinity. While in Rio, he also bought about 100 collections from Riedel and about 500 collections from Clausen, which were made in the states of Rio de Janeiro, São Paulo, and Minas Gerais, which he re-numbered and integrated into his collections. He also made significant collections in the state of Bahia, and a few collections in and around Recife (Pernambuco). Based on the preceding collections, Casaretto published a total of 101 names (in 36 plant families, delimited according to APG III), of which, according to the present study, 27 names are currently accepted, 12 serve as basionyms for currently accepted names, 7 are illegitimate due to superfluity, and 55 are heterotypic synonyms of previously published names. All the 101 names of Casaretto are hereby typified, and Eugenia casarettoana Delprete is here proposed as a substitute name for an illegitimate later homonym. In addition, a lectotype and an epitype for Couratari estrellensis Raddi are here designated.
