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. 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,[2] and in western Ecuador it is known as pambil.

These palms are canopy trees growing to 20–35 m tall. I. deltoidea is easily recognized by the prominent bulge in the center of its trunk, and the stilt roots, which form a dense cone up to 1 m in diameter at the base. It can thus be easily be distinguished from Socratea exorrhiza (which also bears stilt roots), as the stilt roots of the former are much less tightly appressed upon one another. The leaves are up to 5 m long, and pinnate. The numerous pinnae are fan-shaped, and held in various planes. The fruit is a 2-cm diameter drupe, and primarily dispersed by bats.

The fruit are also eaten by humans, and the wood is used for construction and in handicraft.[2]

Taxonomy and systematics

Almost all species at one time placed in Iriartea have now been moved elsewhere or placed in synonymy with I. deltoidea. Dictyocaryum, Iriartella, Socratea and Wettinia were split off from the Iriartea but are close relatives, together with the present genus forming the tribe Iriarteeae. Less closely related palms which were at one time presumed to be Iriarteeae are members of the genera Ceroxylon, Drymophloeus, and the monotypic Deckenia nobilis.[1]

There remain a few somewhat dubious taxa, published in L'Illustration Horticole in 1881. These may be synonyms or good species, but probably the former:[1]

  • Iriartea affinis H.Karst. ex Linden
  • Iriartea costata Linden
  • Iriartea glaucescens Linden
  • Iriartea pygmaea Linden (nomen nudum)
  • Iriartea xanthorhiza Klotzsch ex Linden
  • Iriartea zamorensis Linden
