Sacapellote

Acourtia microcephala, commonly known as sacapellote, is a perennial herbaceous plant belonging to the Asteraceae family. This species is native to the temperate regions of South America, particularly found in Argentina, Bolivia, and Paraguay. Acourtia microcephala typically exhibits a growth habit that ranges from 30 to 100 centimeters in height, with a somewhat bushy form characterized by a rosette of basal leaves. The stems are erect and may be branched, contributing to its overall bushy appearance.

The leaves of Acourtia microcephala are lanceolate to ovate, measuring approximately 5 to 15 centimeters in length, with a serrated margin and a prominent midrib. The upper surface of the leaves is usually glabrous, while the underside may be slightly hairy. The flowering period occurs primarily in late summer to early fall, during which the plant produces dense, globular flower heads that contain numerous small, tubular florets. These flower heads are typically surrounded by involucral bracts that are green to purplish in color. The fruit of Acourtia microcephala is a small achene, which is dispersed by wind and animals, facilitating its spread in suitable habitats.

Ecologically, Acourtia microcephala plays a role in local ecosystems as a nectar source for various pollinators, including bees and butterflies. It is also used in traditional medicine by indigenous peoples for its purported health benefits. The plant has adapted to thrive in disturbed areas and can often be found in open grasslands and along roadsides, demonstrating resilience to environmental changes. Its ability to grow in a range of soil types and conditions further enhances its ecological versatility.
