- Podmrvka (Notholaena) je rod kapradin z čeledi křídelnicovité. Jsou to suchomilné kapradiny s jednoduše nebo vícenásobně zpeřenými listy, rostoucí zejména na skalnatých podkladech. Podmrvky jsou rozšířeny zejména v Asii a Americe, po jednom druhu jsou zastoupeny v Evropě, Africe a Austrálii. V České republice se na jediné lokalitě vyskytuje podmrvka hadcová, rostoucí na hadcích u Mohelna. Rod Notholaena v tradičním pojetí zahrnuje asi 30 druhů, podle výsledků fylogenetických studií však není monofyletický. Americké druhy jsou někdy oddělovány do samostatného rodu Chrysochosma nebo naopak druhy Starého světa do rodu Paraceterach či Paragymnopteris. Taxonomická revize rodu Notholaena však nebyla dosud publikována. Ilustrace podmrvky hadcové z roku 1845 (cs)

- Notholaena (from Ancient Greek νόθο(ς) + χλαῖνα), cloak fern, is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. Ferns of this genus are mostly epipetric (growing on rock) or occurring in coarse, gravelly soils, and are most abundant and diverse in the mountain ranges of warm arid or semiarid regions. They typically have a creeping or erect rhizome and leaves that are pinnatifid to pinnate-pinnatifid with marginal sori protected by a false indusium formed from the reflexed margin of the leaf. Members of Notholaena also have a coating of whitish or yellowish farina (a powdery secretion that prevents desiccation) on the surfaces of the leaves. The farina is often limited to the abaxial (lower) leaf surface, but may occur on the adaxial (upper) leaf surface as well. Members of the related Pentagramma genus have a similar lower leaf-surface farina. The similar genus Argyrochosma also has farinose leaves, but in that genus the ultimate segments of the leaves have entire margins and *are distinctly stalked, whereas in Notholaena the ultimate segments are usually lobed or pinnatifid and sessile or subsessile. Notholaena has in the past been used as a "catch-all" genus for a wide variety of species that did not fit well in other arid fern genera but it has more recently been defined in a much narrower sense, making the genus much more morphologically and evolutionarily coherent. The genera Argyrochosma and Astrolepis were recently segregated from Notholaena, and other former members of Notholaena are now in the genus Cheilanthes. (en)
- Notholaena is een geslacht met bijna 30 soorten varens uit de lintvarenfamilie (Pteridaceae). Notholaena-soorten zijn voornamelijk in de Nieuwe Wereld te vinden. Het zijn overwegend lithofyten uit warme, droge en rotsige biotopen. Eén soort, Notholaena marantae, komt ook voor in het zuiden van Europa. (nl)
- Notholaena är ett släkte av kantbräkenväxter. Notholaena ingår i familjen Pteridaceae. (sv)
