Abstract

Elaphoglossum mickeliorum, a new species from the eastern slopes of the Peruvian Andes, is here described and illustrated. It belongs to E. sect. Polytrichia, which is characterized by the presence of subulate scales and absence of hydathodes on the sterile leaves of adult sporophytes. Herbarium specimens of this new species were first collected by Alwyn H. Gentry ca. 40 years ago, but these got readily confused with E. erinaceum and went undescribed since then. The new species differs from members of the E. erinaceum complex by having a nearly continuous band of planar, nonsubulate scales along the laminar margins of sterile leaves. Based on this character, E. mickeliorum resembles species such as E. glaziovii, E. ornatum, and E. scolopendrifolium. It differs from these by the presence of minute glandular hairs on petioles and costae. A distribution map and a figure with line drawings are also provided. For comparative purposes, the line drawing includes E. blepharoglottis, which is here illustrated for the first time.

Acknowledgments

This paper is part the doctoral dissertation of the first author, done under the supervision of the second author through the joint Graduate Studies Program of the New York Botanical Garden and City University of New York. Major funding for this study was provided by CAPES/Fulbright scholarship to the first author for four years of graduate school. The first author also acknowledges financial support from The American Fern Society (AFS Travel Award, 2011 and 2013), The American Society of Plant Taxonomists (ASPT Travel Award, 2011 and 2013), the International Association for Plant Taxonomy (IAPT Research Grant, 2014), and the Smithsonian Institution (Cuatrecasas Award, 2011). We thank the curatorial staff of MO, NY, UC, and US for facilitating access to their collections. Special thanks go to Alan Smith and his wife, Joan Smith, who kindly hosted the first author during a visit to UC. The line drawing (Fig. 1) was prepared by Mr. Haruto Fukuda. The distribution map (Fig. 2) was made with QGIS v. 2.14.2-Essen. We also thank Alan R. Smith and Alejandra Vasco for their critical reviews of the manuscript.
