We investigated its phylogenetic relationships within Elaphoglossum based on analyses of three non-coding, plastid loci (trnL-trnF, rps4-trnS, atpB-rbcL) in 30 other species representative of the diversity of sections. Our results show that E. nidusoides belongs to section Squamipedia. This is an unexpected phylogenetic position regarding the morphology of the new species, which exhibits short-creeping rhizomes, phyllopodia, fronds glabrous or nearly so, fronds more than 15 cm long, and lacks the characteristic peg-like aerophores on the rhizome. Nevertheless, its position as sister-taxon to another Malagasy species, E. marojejyense, is supported by the succulent fronds.} }
