''Thaumatophyllum'' (formerly '' Meconostigma'') is a genus of flowering plants in the arum family, Araceae. Its species are native to northern (tropical) South America.

Taxonomy

The genus ''Thaumatophyllum'' was erected by Heinrich Wilhelm Schott in 1859, with the sole species '' Thaumatophyllum spruceanum''. In 1962, G.M. Barroso transferred ''T. spruceanum'' to '' Philodendron''. (However, the transfer was not made correctly and Barroso's name ''Philodendron spruceanum'' is illegitimate.) While in ''Philodendron'', ''T. spruceanum'' was placed, along with other species, in subgenus ''Meconostigma''. A series of

. In 2018, it was proposed that subgenus ''Meconostigma'' should be raised to the rank of genus, under the name ''Thaumatophyllum''. The proposal has been accepted by

, among other taxonomic databases. The generic epithet ''Thaumatophyllum'' comes from Ancient Greek (, "miracle") + (, "leaf").
