Description:
Species Description - Rhizome scales dark brown to blackish, 0.5–1 mm long, ovate to lanceolate, glabrous; stipes 0–1 cm, sparsely to moderately setulose, the setulae castaneous, 0.3–0.5 mm, bifurcate with a pale glandular cell and short base; blades 4–15 x 0.3–0.5 cm, linear, pinnatisect all along the length of blades, glabrescent or sparsely setulose on the margins and on both surfaces; segments 1–1.5 mm wide at the base of the sinuses; rachises straight (not flexed), with hairs similar to those of stipes; fertile veins visible only proximal to the sori; hydathodes one per fertile segment; sori elongate, slightly imbedded and enclosed by the somewhat conduplicate segments; sporangia glabrous; 2n=64 (CR).

Polypodium limulum Christ, Bull. Soc. Bot. Gene`ve, se´r. 2, 1: 218. 1909. Xiphopteris limula (Christ) Pic. Serm., Webbia 28: 472. 1973. Grammitis limula (Christ) L. D. Go´mez, Brenesia 8: 47. 1976. Syntypes. Costa Rica. San Jose´: La Palma, Pittier 708; Tonduz 12595; Brade 79; Werckle´ s.n. (all P; isosyntype of Tonduz 12595 at US!).
Lellingeria limula is distinguished from L. delitescens by being pinnatisect to the apex of the blades, thus lacking the slightly modified terminal portion found in L. delitescens. Blade segments are often somewhat conduplicate, a feature not found in close allies. The Chiapas specimens were cited under Grammitis delitescens by Smith (1981).
