Bolivia and Brazil along banks of rivers, larger in forests than along the banks (fide d'Orbigny), flowering November (Prance et al.) to January (d'Orbigny), fruiting April (d'Orbigny) to July (Prance et al.). (H.E. Moore, Chelyocarpus and its Allies Cryosophila and Itaya (Palmae). 1972)A

Discussion

  • Chelyocarpus chuco stands somewhat by itself in the genus as noted earlier The presence of a prophyll on som~ primary branches is unusual in the alliance, for such have not been observed in Cryosophila nor in Itaya. The less deeply lobed leaf with its green under. surface further sets the species apart from others in Chelyocarpus, from Itaya, and from most in Cryosophila. (H.E. Moore, Chelyocarpus and its Allies Cryosophila and Itaya (Palmae). 1972)A

Photo by S. Kiem. wide basally, 1 cm. wide apically, with brown furfuraceous scales at first, becoming glabrate; hastula deltoid or truncate-deltoid, 1.5-2.5 cm. long, 2-3 cm. wide at base; blade thin, green, to 1.05 m. long at center, 1.8 m. across, divided centrally to within 1.5-2 cm. of the base, divided laterally one-fourth to nearly three•fourths to the base into 15-24 lanceolate l-ribbed segments on each side, these mostly grouped in pairs toward the margins or irregularly toward the center, the ultimate segments to 50 cm. long, 2.5-6 cm. wide, each with a midrib, 2-3 lateral secondary and several finer tertiary nerves on each side more prominent below than above, flexuous cross-veinlets prominent on both surfaces when dry, proximal segments often conspicuously narrowed and "shouldered" toward the acute or very briefly bifid apex, lower surface of blade green but paler than upper surface, very densely beset with minute, shining, translucent dots. Inflorescences 3-4 (teste Martius), to more than 5.5 dm. long; sterile bracts 2 (or more?), densely light brown floccose-lepidote outside, glabrous within, ca. 21 cm. long; branches 5-7, each subtended by a fertile bract similar to the peduncular bracts but progressively smaller, the lowermost branches bearing a membranous prophyll to 12 cm. long, upper branches with incomplete prophylls or prophyll lacking, main axis and branches more or less flattened, branches mostly curved with flattened base to ca. 18 cm. long, 1.3 cm. wide in fruit, fertile portion to ca. 20 cm. long; rachillae to 8 cm. long, subtended by narrowly triangular, membranous, tomentum. tipped bracts to 15-17 mm. long on lowermost branches, shorter above, shortly adnate above the bract and with a short sterile base. Flowers sessile or briefly pedicellate, borne singly in a spiral on the rachillae, bracts short; perianth 2-2.5 mm. long, creamy white, erect at anthesis; sepals 3, connate for ca. 0.5 mm., 2.0-2.5 mm. long, lobes deltoid; petals 3, about as long as the sepals, distinct, imbricate; stamens 6, filaments broad and thick basally, subulate above, anthers exserted and spreading from the narrow mouth of the perianth; carpels 3. Fruit globose or depressed.globose, with persistent thickened perianth, 1.62.0 cm. wide, 1.6-1.8 cm. high; epicarp not tessellate; mesocarp rather thin; endocarp membranous; seed brown, depressed-globose, ca. 1.6 m. wide, 1.4 cm. high; embryo above the middle.

The constructors of houses choose the species based on the planned lifetime of the building, available labor time and the durability of the construction material. For making the roof, the leaves of palms such as jatata (Geonoma deversa) palla (Attalea butyracea), patujú, hoja redonda (Chelyocarpus chuco), asai and motacú are used.

  • Chelyocarpus chuco (Mart.) H.E.Moore: Las hojas se utilizan para la elaboración de techos y sombreros. Ocasionalmente, se las utiliza para cerrar las aperturas laterales de los techos de las casas en las zonas rurales. Por su tamaño relativamente pequeño y hojas redondeadas, esta palma tiene buen potencial para ser utilizada en la ornamentación de plazas y jardines. (Gutiérrez-Vásquez, C.A. and R.
