Butia eriospatha is a small species of Butia palm endemic to the highlands of southern Brazil. It is very similar to B. odorata, but is easily distinguished from this species by the distinct spathes which are densely covered in rust-coloured, woolly hairs. Indeed, the specific epithet is derived from Greek ἔριον, wool, and Latin spatha, which refers to the spathe. It has been given the name woolly jelly palm (UK) or wooly jelly palm (US) in English. Vernacular names for it where it is native are butiá-da-serra, butiázeiro, butiá-veludo, butiá butiá verdadeiro, butiá-do-campo, yatáy and macumá.
