Abstract. Besleria naquenensis is described and illustrated on the basis of a collection from the understory of seasonally flooded forests drained by black waters located in the lower “Río (Caño) Naquén,” northwestern base of “Serranía de Naquén,” upper Guainía River basin, Guainía Department, Colombia, and its relationships with related species are discussed. This new species shares features with three species (B. gibbosa, B. neblinae, and B. yatuana) of section Neobesleria subsection Axillares. Morphologically, it is closest to B. yatuana, but it differs in its leaves, inflorescences, calyx, and corolla. In addition, habitat information, a distribution map, and data of its conservation status are included. An identification key of 27 species of Besleria found in the Rio Negro basin (Brazil, Colombia, and Venezuela) and adjacent regions is also provided. This new species elevates to 66 the number of Besleria taxa for the flora of Colombia, the country with the highest diversity of the genus.
摘要根据哥伦比亚瓜伊尼亚省瓜伊尼亚河流域上游“Río（Caño）Naquén”下游、“Serranía de Naquèn”西北部基地的黑色水域排放的季节性洪水森林下层的收集资料，描述和说明了纳奎嫩贝斯勒菌，并讨论了其与相关物种的关系。这一新物种与Axillares的Neobesleria分区的三个物种（B.gibbosa、B.neblinae和B.yatuana）有共同的特征。从形态上看，它最接近于B.yatuana，但在叶、花序、花萼和花冠方面有所不同。此外，还包括栖息地信息、分布图和保护状况数据。还提供了在Rio Negro盆地（巴西、哥伦比亚和委内瑞拉）及其邻近地区发现的27种Besleria的鉴定钥匙。这个新物种使哥伦比亚植物群的Besleria分类群数量增加到66个，哥伦比亚是该属多样性最高的国家。

Abstract. Calliandra subspicata (Fabaceae) hitherto had been reported from Pernambuco and Bahia, states of the Northeast Region of Brazil. Here we report this species from Paraíba state, the third state of this region. It was observed and collected at the Pico do Jabre State Park, a conservation unit situated at the residual massif of the Depression Sertaneja on the Borborema Plateau, which reaches an altitude of 1197 m. The identification was made on the basis of current literature. A morphological description, images, information about the area where the taxon was collected, and a key for identification of the species of Calliandra recorded in Paraíba state are provided.

Abstract. An illustrated key is presented to species in the Venezuelan clade of Espeletia (Asteraceae), based on herbarium specimens, virtual herbaria, and fresh samples from field collections. The 54 Espeletia species in this clade are documented: (i) 48 entirely endemic to the Venezuelan Andes, (ii) 2 found as well in the Venezuelan Cordillera de la Costa, the eastern section of the Colombian Cordillera Oriental, and the Sierra Nevada de Santa Marta, and (iii) 4 endemic to the northern section of Colombian Cordillera Oriental and Sierra de Perijá. Schematic representations of leaves of all species are provided, including important diagnostic characters such as length-to-width ratios, and the shape, density, or angles of secondary nerves. Additional diagnostic characters are also described or illustrated for some species, such as the type of indumentum on leaves, the structure of the inflorescence, the size of the capitulum, and the color of ray ligules. The key has been shown to allow identification of species using both herbarium samples and fresh material, and given the predominant use of vegetative characters it is also useful on some monocarpic rosette species that are frequently found in the vegetative stage.

Abstract. Orchidaceae is one of the most threatened families of vascular plants in the world, and in recent years, species distribution models (SDM) have been used as a tool to inform the conservation status of several species. However, the usefulness of SDM depends on appropriate knowledge of the use and limitations of these tools, otherwise there is a risk of getting erroneous models leading to wrong decisions in conservation plannning. We present the distribution model of Lepanthes mucronata in South America based on current and accepted knowledge in this discipline. The representativeness of protected areas for Colombia is evaluated, as well as ecosystems where it is present and its risk of extinction based on criteria of the IUCN. After reviewing these parameters, we found that Lepanthes mucronata meets the criteria for Least Concern (LC) IUCN status. We expect this investigation to serve as an appropriate example of this type of analysis and as a reference for future work in the conservation of this plant family.
