Calathea myrusma
Calathea myrusma is an old name published by Körnicke in Gartenflora in 1858, most likely from a plant in cultivation; GBIF also knows the spelling 'myrosma'. There are no wild records and no documented origin, so no measured climate exists. Treat it like a typical lowland tropical American Calathea: warm, humid, shaded and evenly moist.
Where it grows wild
Nothing is recorded about its wild habitat. Like most Calathea it is presumably a terrestrial shade herb of humid tropical American forest.
Unknown; no records carry an elevation.
