Central America to Ecuador W of the Andes, and in the W part of the Amazon region from Venezuela to Bolivia. Perhaps the most common native tree species in Ecuador, occurring in all provinces that include moist lowland areas. (Borchsenius F., Borgtoft-Pedersen H. and Baslev H. 1998. Manual to the Palms of Ecuador. AAU Reports 37. Department of Systematic Botany, University of Aarhus, Denmark in collaboration with Pontificia Universidad Catalica del Ecuador)A


  • The holotype of Iriartea deltoidea consists of five sheets with a seedling, section of leaf, and piece of rachilla with pistillate flowers. The iso type is similar. This species is interpreted from the type, description, and a more recent collection from the type locality (Henderson 537).

    The type of Deckeria corneto consists of four sheets, with a leaf section and rachillae with sta-minate and pistillate flowers. This species is interpreted from the type, description, and other collections from at or near the type locality (Henderson et al. 119, Triana 1733-2, Dugand &Ja-ramillo 2921, Moore & Dietz 9865). Karsten described the species as having 16-20 stamens. The type has 15 stamens, and Henderson et al. 119 has 13-14. Karsten's count is considered incorrect, and D. corneto is not maintained.

    The type of Iriartea ventricosa consists of a single sheet with a leaf section only. Dugand (1942) believed that the type locality could be in present-day Colombia. This species is interpreted from the type and the description. Martius distinguished his new species on its ventricose stem, pinna shape, and villose staminate calyx. The character of the stem swelling is of no significance. It is usual in Iriartea for lowland populations below ca. 300 m to have markedly swollen stems, and for upland populations to have more or less cylindrical stems. However, there are many exceptions in any population, and the character is physiological, and not of any taxo-nomic significance. The characters of the pinna shape and calyx trichomes are of little importance. All Iriartea specimens examined with young staminate flowers have villose sepals, but these trichomes soon fall from the sepals.

    The type of Iriartea phaeocarpa consists of a seedling only, which is illustrated in Martius (1847). This species is interpreted from the type, the description, from Martius (1847), and more recent collections from near the type locality (Nee & Solomon 30325). Martius recognized that this species was similar to I. ventricosa, but distinguished it by its few peduncular bracts, pinnae size, and fruit size. The number of peduncular bracts, three, is obviously based on a misinterpretation, probably most had fallen when the illustration was made. The illustration is, in any case, incomplete (Burret, 1930). Pinnae shape and fruit size are not considered significant.

    The type of Iriartea gigantea consists of leaf sections and rachillae with staminate and pistillate flowers. This species is interpreted from the type, the description, and from recent collections from at or near the type locality (Moore 6574, Moore & Parthasarathy 9413, Tomlinson 65B, Henderson 42). Burret distinguished his new species by its thicker rachillae with seven series of triads, and by its longer fruit. These differences are slight and are not considered significant.

    The type of Iriartea weberbaueri consists of approximately 30 fruits. This species is interpreted from the type and the description. Burret distinguished the species by its larger fruits and cylindrical stern. The type fruits are 2-2.5 x 2.2-2.5 cm, and easily fall within the range observed in other specimens. As discussed above, the character of the stem swelling is of no taxonomic significance.

    The type of Iriartea megalocarpa is no longer extant at B, and no isotypes are known. A recent collection from the type locality, the neotype, is typical Iriartea deltoidea. (Henderson, A. 1990. Introduction and the Iriarteinae. Flora Neotropica Monograph 53.)C


  • The outer part of the stems are used throughout its range for building purposes, e.g., floors, posts, poles; also for blowguns, bows, harpoons and arrow points; and also for firewood. The leaves are used for thatching and basketry. The heart and seeds are occasionally eaten. The inside layer of the leaf sheath is used to give women strength in labor (Shemluck & Ness 163, Ecuador). Hollowed-out stems are used as coffins by Embera Indians in Colombia (R. Bernal, pers. comm.). Steven King (pers. comm.) reports that in northern Peru Angotere-Secoya and Quechua people use the stems of I. deltoidea as canoes. Large specimens are selected and carefully felled. The soft central ground tissue is removed from the center of the stem, and base and apex fashioned into bow and stern. The canoes are widely used for shortening trips, especially long overland trips where short-cuts can be made by river. Canoes last about two or three months. Such is the demand for these temporary canoes that many of the larger specimens of Iriartea have been felled in this area. Rodrigo Bernal (pers. comm.) reports that in Colombia the Embera Indians of the Choco tie the stems together and use them as rafts. Since these are so heavy they are only used for downstream travel.

  • Canopy palm. Stem to 20 m tall and 20-40 cm in diameter, often swollen in the middle. Base supported by a 1-2 m tall cone of black stilt roots, these 3-5 cm in diameter.

Inflorescence cream coloured in flower, the numerous pendulous branches to 1.5 m long, borne on a short curved axis. Fruits dull bluish black, globose, ca. 3 cm in diameter.
