Flowers pale yellow to purple tinged, staminate flowers near the base of the inflorescence 3.5–4.0 mm long, sessile; sepals 3, distinct, linear, imbricate but briefly connate at base, acute to mucronate, membranous, glabrous; petals 3 distinct, unequal, obovate, valvate, fleshy, glabrous, with inconspicuous venation, ca. 3.5–4.0 × 2 mm, acute tips; stamens 6, pale yellow, distinct, 2.2–2.8 mm long, with filaments 1–2 mm long; pistillode trifid, not reflexed, less than 0.5 mm long. Pistillate flowers, globose to ovoid, sessile 3.5–4.0 × 2.5–3.5 mm; sepals, glabrous, without visible venation 3–3.5 × 2.5–3.2 mm, coriaceous, imbricate, sepals subequal, acute, keeled to faintly keeled at tip; petals 3, distinct, imbricate at base, valvate at apex, triangular, faintly nerved, especially near the base, glabrous, 2.5–3.5 × 2–3 mm, valvate portion 0.5–1.5 mm long, acute; gynoecium 2–2.7 × 1.5 mm. glabrous, stigma 0.5–0.8 mm long, and staminodes 0.6–0.7 mm long, 3– 6 dentate to smooth and truncate. Fruits purple when mature, 1.2–2.0 × 1.2–1.5 cm, ovoid; cupule (persistent perianth) reddish brown, 0.8–1.0 cm in diam. × ca. 0.3–0.4 cm high; petals longer than sepals, staminodial ring truncate, 1 mm high × 3–4 mm diam.; epicarp, dark purple when mature, smooth and glabrous; mesocarp pale yellowish, fleshy, non-fibrous ca. 1–2 mm thick; endocarp nearly spherical, ca. 1.0–1.6 × 1.0–1.3 cm, 1 mm or less thick, hard, bony, dark brown to nearly black, apex with no distinctive protuberance or beak, interior smooth, monovittate, round in crosssection, outer surface nearly smooth, pores 3 nearly even with surface and subequatorial, sutures visible especially at apex; seed 1, spherical to ellipsoidal, ca. 0.8–1.2 × ca. 1 cm, endosperm white, homogeneous. Germination remote tubular, eophyll simple, narrowly lanceolate.
Open grasslands and savannas (cerrados); flat terrain with deep sandy soils and with few, and sparsely distributed shrubs and trees, frequently associated with Allagoptera campestris. The plants are restricted to the open short grasses rather than in the adjacent low weedy scrub. Most of palms had flowers or developing immature fruit with only one with mature fruit in February.
