Discusión taxonómica

(In relation to the synonym Lellingeria hellwigii) This species is very closely allied to L. myosuroides (see Excluded Species), which is widespread in tropical America (see also discussion under L. prionodes for comparison with that species and L. delitescens). Lellingeria myosuroides has longer rhizome scales (1.5–2 mm long), scattered bifurcating hairs on the stipes and rachises, sinuses on the fertile portion 0.3 mm deep, sterile lobes narrow and broadest at the base (1.5–2 mm long, 0.5–0.8 mm wide at midpinna), and veins in the fertile portions darkened beyond the receptacle, almost to the blade margin.A
