Based on recent collections, we describe a new species of scaly tree fern, Cyathea giraldoi, from northern Colombia and discuss its ecology. The new species differs from putative close relatives by a character combination including a small size, often decumbent trunk, strongly arching fronds with drooping tips, nearly triangular lamina, thick scurf of matted arachnoid squamules, and frequent production of adventitious buds.

Con base en colecciones recientes, describimos una nueva especie de helecho arborescente, Cyathea giraldoi, del norte de Colombia y describimos su ecología. La nueva especie difiere de especies probablemente emparentadas en una conbinacion de caracteres que incluyen un tamaño pequeño, frondes marcadamente arqueados y con ápices caídos, lamina casi triangular, caspilla densa de escuámulas aracnoides entrelazadas y producción frecuente de yemas adventicias.



We thank Ingrid Olivares and María José Sanín for help with the acquisition of collection permits and Alejandro Mejía for company and logistic assistance in the field. Field explorations were guided by Sr. Moro from Vereda Chanchón, and his family provided generous hospitality. Herbarium visits were graciously hosted by Rocío Rojas and Rodolfo Vázquez (HOXA), Robbin Moran (NY), and Blanca León (USM). We thank the editors and reviewers for improving earlier versions of the manuscript. This work was conducted under the research project POPCORN (Using Population genomics, Phylogenetics, and Community Ecology for understanding Radiations in Neotropical mountains) funded by the Swiss National Fund (grant SNF-310030L_146906).
