A distinctive new species of Elaphoglossum (Dryopteridaceae) from lowland Bolivia

Abstract

Elaphoglossum praetrepidans M. Kessler, characterized by long-creeping rhizomes with entire rhizome scales, ill-defined phyllopodia, linear-elliptic, firmly chartaceous blades lacking hydathodes, and ovate to lanceolate, basifixed to peltate, denticulate blade scales, is described based on a single specimen from lowland Bolivia. This combination of characters suggests affinity to Elaphoglossum section Lepidoglossa, but precludes placement in any of the established subsections within that section. © 2008 The Linnean Society of London.
