Discussion

  • Butia paraguayensis is apparently closely related to B. yatay, and may only be a variety of this species. At present, it can be distinguished mainly by its generally smaller dimensions (except for the similarity in SIze of pistillate flowers) .

Common Name

  • Yatay guazu (Paraguay), yatay poñi (Argentina), coco amargoso (Sao Paulo, Brazil). (Glassman, S.F. 1979: Re-evaluation of the Genus Butia With a Description of a New Species)A
