Introduction
I am interested in the taxonomy of plants, especially in the order Myrtales (Melastomataceae) and Mistletoes (Santalales). I am training in topics related to nomenclature, floristic, morphology and evolution.

Background and aims – Ongoing studies on Colombian mistletoes revealed an undescribed species of Maracanthus (Loranthaceae) endemic to the Colombian Eastern Cordillera (Cordillera Oriental). This species is described and illustrated here, and a checklist of the species accepted in Maracanthus is also provided, including a taxonomic key, references...
During the development of the taxonomic treatment of Ernestia we came across a taxonomic novelty and a species for which taxonomic verification was needed from Colombia. Herein, we propose Ernestia rheophytica a new species belonging to the sensu stricto clade of the genus, and clarify the identity of Acisanthera goudotii, now treated as E. goudoti...
The Cyphostyleae are an exclusively neotropical and small tribe, yet poorly studied and collected. It includes 25 species in four genera from low to mid-elevation in the Andes of Colombia, Ecuador, and Peru. Even though the group is not species-rich, some or all of its species present several characters otherwise rare in the family: leaves with pin...
Alloneuron trinervium, a new species of Melastomataceae known only from the type locality in Antioquia Department, northwestern Colombia, is described and illustrated. This new species is the only one in Alloneuron with three basal veins, a venation pattern that is intermediate between semi-craspedodromous (found in all other members of the genus)...
A new species of Melastomataceae from the Andes of Colombia is described and illustrated. Miconia lorenaensis is part of Miconia sect. Amblyarrhena, and it differs from other species in this group by the combination of branches, petioles and leaves covered by scattered short dendritic trichomes, 7-nerved peltate leaves, acuminate or cuspidate apex...
Se describe e ilustra Allomaieta pterocalycina, una nueva especie para el departamento de Antioquia, Colombia. Difiere de las demás especies descritas para el género por su hipanto y caliptra con proyecciones conspicuas a manera de alas. El nuevo taxón crece en ambientes umbrófilos al interior de remanentes de bosque en buen estado de conservación,...
Phoradendron killipii is an endemic species from Colombia, initially known only from the original material. Ten herbarium sheets of this species were found during taxonomic studies of Colombian Viscaceae, allowing to figure out some aspects that remained unclear since P. killipii was published, until now. The morphology of P. killipii fruits and st...
Aetanthus alternifolius F.J. Roldán, Carmona, Alzate & J.S. Murillo (Loranthaceae) is newly described and illustrated from the department of Santander in northeastern Colombia. This new mistletoe species, known only from the type locality, is discriminate by its indeterminate shoots, alternate or subopposite, obovate leaves, cymose inflorescences b...
A new species of the hemiparasitic genus Oryctanthus from Colombia is described and illustrated. This species is known only from two nearby localities and it can be distinguished from similar species by its terete stems being grayish at maturity, coriaceous leaves with secondary inconspicuous venation and completely furfuraceous inflorescence pedun...
Oryctanthus grammatus es una especie ya descrita en el 2011 en el área biogeográfica del río Magdalena, Colombia, de la cual se conoce únicamente su espécimen tipo, recolectado en 1916 en el departamento de Bolívar. En el presente estudio se reporta un espécimen adicional, encontrado en el departamento de Antioquia 71 años después de su primera rec...
Libro conmemorativo, aniversario 50 del Herbario Universidad de Antioquia (HUA).
In order to provide nomenclature and taxonomic clarity, nine lectotypes are designated for plants currently circumscribed in Graffenrieda. In addition, the typification for some species was analyzed and clarified and we discuss the occurrence of three cases of inadvertent lectotypifications.
RESUMEN El género neotropical Furcraea Vent. es ampliamente cultivado para la production de fibras conocidas como Fique o Cabuya. Se realizó un análisis histológico de las hojas de tres especies cultivadas en Colombia, con la finalidad de realizar la description comparativa entre ellas. Diferentes secciones de hojas listas para su cosecha fueron pr...
Se describe la anatomía foliar de las especies Gaiadendron punctatum y Tripodanthus belmirensis, al objeto de estudiar posibles caracteres
que permitan una identificación precisa de estos dos géneros de la familia Loranthaceae, de hábito arbustivo o arbóreo. Las muestras
se procesaron y sometieron a tinción con técnicas clásicas para su observación...
Páramos are high-elevation isolated ecosystems in the Andes characterized by specific flora. This flora includes a number of endemic species and some taxa phylogenetically related to temperate lineages (van der Hammen and Cleef 1986). There are six páramo units or complexes in the Department of Antioquia, located in northwestern Colombia. For five...
