Abstract: Baseline checklists for the Leguminosae (Fabaceae), Araceae and Myrtaceae from the Colombian department of Boyacá are available from the Catalogue of Plants and Lichens of Colombia. These lists were supplemented by thorough herbarium and literature searches by a collaborative group of local and international experts, and further enhanced by local field collections. The result is authoritative taxonomic checklists for the three families including data regarding habit, plant uses and species conservation risk assessments for a subset of species. The checklists have notably increased the number of species reported from Boyacá and provide reliable, taxonomically up-to-date inventories for those families. Checklists are based on specimens vouchered in local herbaria and revised specimen metadata is lodged in the Colombian biological information platform CEIBA. The initiative demonstrates how relatively low levels of funding allow taxonomic experts working in networks to rapidly improve the taxonomic understanding of angiosperm species ersity in mega erse countries like Colombia.

Abstract: The specimens collected by José Jerónimo Triana are an important legacy of the first major scientific expedition organized by the government of Nueva Granada , present‐day Colombia: the Chorographic Commission. After finishing his duties in the Commission, Triana gave to the Colombian government a complete set of his specimens in 1856, along with a catalog where he taxonomically organized and numbered his collections. After traveling to Europe in May 1857, carrying part of his herbarium, Triana prepared a new catalog in which he reorganized the numbering of his collections, and added at least three additional number series: the serial numbers (i.e., Triana “collection numbers”), the “Linden” numbers, and the number of duplicates for each gathering. The use of different number series in the two catalogs and on the labels of duplicates of the same gathering stored in numerous herbaria around the world has produced ambiguity in the designation of type specimens collected by Triana. These nomenclatural issues were analyzed, and a guideline is presented for lectotypifying plant names for which Triana's specimens were used as types. Sixty‐five Triana specimens already deposited in COL were newly identified as types of 62 species names from 36 families, after establishing their proper correspondence to duplicates currently stored in different European herbaria.

Abstract: Thirteen new species of Myrtaceae from Colombia are described and illustrated information about the habitats in which these species are growing, the evaluation of its conservation status, and its affinities are included. Besides, five new records of native and introduced Myrtaceae are reported for Colombia. Also, a new combination of a Myrtaceae species previously described as Calycorectes is proposed here under the genus Eugenia.

Abstract: Here we present the first two complete plastid genomes for Brunelliaceae, a Neotropical family with a single genus, Brunellia . We surveyed the entire plastid genome in order to find variable cpDNA regions for further phylogenetic analyses across the family. We s led morphologically different species, B. antioquensis and B. trianae , and found that the plastid genomes are 157,685 and 157,775 bp in length and display the typical quadripartite structure found in angiosperms. Despite the clear morphological distinction between both species, the molecular data show a very low level of ergence. The amount of nucleotide substitutions per site is one of the lowest reported to date among published congeneric studies ( π = 0.00025). The plastid genomes have gene order and content coincident with other COM (Celastrales, Oxalidales, Malpighiales) relatives. Phylogenetic analyses of selected superrosid representatives show high bootstrap support for the ((C,M)O) topology. The N-fixing clade appears as the sister group of the COM clade and Zygophyllales as the sister to the rest of the fabids group.

Abstract: Myrcia DC. sect. Calyptranthes (Sw.) A. R. Lourenço & E. Lucas is a section of the Neotropical genus Myrcia with ca. 260 known species. This paper provides a taxonomic revision of 89 species occurring across South and Central America, including the Amazon, Andes, Guiana Shield, and Mesoamerica, and extending into the Caribbean archipelago, but not including those previously treated from the Atlantic Forest of Brazil. The treatment includes an identification key, informal taxonomic groupings and notes, geographic distribution information, and extinction risk assessments. Figures illustrating key morphological characters of the genus are provided including common leaf, flower bud, and inflorescence arrangements. Ten new synonyms, eight new lectotypes, and four new combinations are proposed, and a key to treated species is supplied.

Abstract: The Sierra Nevada de Santa Marta (SNSM), the world’s highest coastal mountain range, has long been recognized for its high levels of biological ersity and endemism but no exhaustive inventory of the flora exists today. Here we present an annotated catalogue of the angiosperm family Melastomataceae from this erse massif. The annotated species list is based largely on the treatment of Melastomataceae for the forthcoming Catalogue of the Plants of Colombia together with several floristic data sources, confirmed specimen records held in different herbaria, and recent field work. The catalogue of Melastomataceae presented here includes 20 genera and 86 species, 21 of which are endemic to Colombia and 15 of those are endemic to the SNSM. We also include floristic similarity analyses to compare the species of Melastomataceae from the SNSM with those from other Colombian biogeographic regions and other Neotropical countries or regions.

Abstract: To date, phylogenetic relationships within the monogeneric Brunelliaceae have been based on morphological evidence, which does not provide sufficient phylogenetic resolution. Here we use target‐enriched nuclear data to improve our understanding of phylogenetic relationships in the family. We used the Angiosperms353 toolkit for targeted recovery of exonic regions and supercontigs (exons + introns) from low copy nuclear genes from 53 of 70 species in Brunellia , and several outgroup taxa. We removed loci that indicated biased inference of relationships and applied concatenated and coalescent methods to infer Brunellia phylogeny. We identified conflicts among gene trees that may reflect hybridization or incomplete lineage sorting events and assessed their impact on phylogenetic inference. Finally, we performed ancestral‐state reconstructions of morphological traits and assessed the homology of character states used to define sections and subsections in Brunellia . Brunellia comprises two major clades and several subclades. Most of these clades/subclades do not correspond to previous infrageneric taxa. There is high topological incongruence among the subclades across analyses. Phylogenetic reconstructions point to rapid species ersification in Brunelliaceae, reflected in very short branches between successive species splits. The removal of putatively biased loci slightly improves phylogenetic support for in idual clades. Reticulate evolution due to hybridization and/or incomplete lineage sorting likely both contribute to gene‐tree discordance. Morphological characters used to define taxa in current classification schemes are homoplastic in the ancestral character‐state reconstructions. While target enrichment data allows us to broaden our understanding of ersification in Brunellia , the relationships among subclades remain incompletely understood.

Abstract: Myrtaceae are represented in Colombia by 24 genera and 167 species, where nine genera and 28 species are introduced (Parra-O. 2015, 2016 Parra & Bohórquez-Osorio 2016). Although a checklist of Colombian Myrtaceae has been recently published (Parra-O. 2016), the continuous study of this family has allowed me to identify five new records for the Country. Cited specimens were examined at COAH, COL, FMB, and HUA herbarium acronyms follow Thiers (2017).

Abstract: A new species, Myrcianthes roncesvallensis is described and illustrated from Andean forests of Tolima, Colombia. Due to the unusual combination of morphological characters in this new species never been found previously in a Colombian Myrtaceae, such as having a closed calyx, dichasial inflorescence and an eugenioid embryo, three DNA barcoding markers (rbcL, matK and ITS) were used to confirm the genus in which this species should be described. Taxonomic affinities of the new species within the genus are discussed.
