Iriartea Iriartea is a genus in the palm family Arecaceae, native to Central and South America. The best-known species – and probably the only one – is Iriartea deltoidea, which is found from Nicaragua south into Bolivia and a great portion of Western Amazonian basin. It is the most common tree in many forests in which it occurs. It is known by such names as bombona (which can also refer to other palms, e.g. "Attalea regia") or cacho de vaca (which can refer to many other plants, like the Bignoniaceae "Godmania aesculifolia" or the orchid "Myrmecophila humboldtii"). In the Murui Huitoto language of southwestern Colombia, it is called "jɨagɨna" or "jɨaìgɨna", in western Ecuador it is known as pambil and in Peru it is known as the pona palm.
