Introduction
I am a botanist by training, and interested in fern systematics and biogeography. I work with themes related to plant diversity (from taxonomy, nomenclature, and species composition) and its links to biogeography and conservation. I am currently working on several aspects of plant composition and endemism in the western slopes of the Andes. I also serve as an associate editor for Revista peruana de biología, and as Subject editor for PhytoKeys.

In its most recent concept, the genus Cheilanthes encompasses three clades distributed across South America, Africa, and Australasia. Previous studies in Peru recorded 23 species; however, advancements in molecular systematic have led to the segregation of eight of them into at least three genera. In this study, 15 species are recognized in the Per...
Societal Impact Statement
Herbaria can be considered plant libraries, each holding collections of dried specimens documenting plant diversity in space and time. For many plant species, these are our only evidence of their existence and the only means of assessing their conservation status. Specimens in all herbaria, especially those in small and of...

Significance
This study provides conservation assessments for 600 US native plants that are wild relatives of important agricultural crops. We found that more than one-half of the species may be endangered in their natural habitats, and that the great majority require further conservation action, both ex situ (in gene banks and botanical gardens) a...
Este trabajo se centra en las recientes decisiones tomadas por el Ministerio de Agricultura del Perú sobre la recolección, propagación y siembra de especies de quina. Señalamos las deficiencias de estas decisiones a la luz de los avances en el conocimiento de la taxonomía y sistemática de Cinchona. Destacamos el papel de la ciencia analizando e inf...
A new species, Campyloneurum atrosquamatum, is described from the western Amazonian region of Ecuador to Bolivia, and from French Guiana and northeastern Brazilian Amazon. The new species belongs to the Repens Clade of Campyloneurum. Previously, it had been identified as C. coarctatum because of its similar lamina size and shape. An earlier phyloge...
Over sixty species representing 14 fern families occur in a research station in central eastern Peru.

During a three-day field course, we covered those three main environments. Five families, Asplenia...
Campyloneurum decurrens is a member of subgenus Decurrentia. Originally described from south eastern Brazil, its distribution was mostly considered to be limited to the Atlantic forest biome. A 19th century collection from eastern Peru and three new additional collections from western Ecuador and north-eastern Peru confirm its presence to the Amazo...

Premise of the study:
Around the world, tropical glaciers and ice caps are retreating at unprecedented rates because of climate change. In at least one location, along the margin of the Quelccaya Ice Cap in southeastern Peru, ancient plant remains have been continually uncovered since 2002. We used genetic analysis to identify plants...
Myrmecophyly is best documented among tropical epiphytes, and myrmecotrophy occurs especially among domatia-forming plants. We report the case of Polytaenium cajenense with "external" domatia and its use by the same symbiont ant as its host Cordia nodosa . This case is interpreted as the result of stochastic events and their relations to pre-existi...
