Description

(Hidayat & Abdurrahman, 2017)

Eupatorium odoratum is a woody herbaceous perennial growing as a climbing shrub to 3 meters in height, typically shorter. The leaves are arranged oppositely, to 15 cm in length, triangular to ovate with an acuminate leaf apex and dentate leaf margin with large teeth.  The vegetative structures are covered with articulate hairs throughout.

The actinomorphic flowers are arranged in corymbs of heads subtended an involucre made of 4 series of phyllaries. The calyx is modified as hairs forming a pappus.  The corolla has 5 fused white to lavender petals.  There are 5 stamens fused to the base of the corolla.  The ovary is inferior with a single locule.  The fruit is an achene at maturity that retains the modified calyx (pappus.

C. odorata can be considered as a major weed in all perennial crops of the humid tropics as well as in forestry. It also invades pastures. Its aggressiveness is much more serious in the Old World tropics where it is an exotic, rather than in its native Americas. C. odorata is found mainly in the humid part of the inter-tropical zone at elevations below 2000 m, in open secondary habitats such as cultivated lands, abandoned or neglected fields, forest clearings, wastelands, along forest trails, fence rows, roadsides and forest margins. Significant differences in four habitats invaded in KwaZulu-Natal, South Africa, concluding that spread along paths and lack of control in state forest mean that it is most abundant there, followed by eucalyptus plantations, and a low abundance in sugar cane fields and communal grasslands is thought to be due to fires and ground cover.

C. odorata is often noted as a native of tropical Central and South America, from Mexico and the Caribbean to Brazil; however, the exact northern and southern limits of its native range remain uncertain and are likely to also include some regions outside of the tropics. USDA-ARS (2007) include as part of the native range Texas and Florida (USA), and all South American countries except Chile and Uruguay, and records from Córdoba in Argentina suggest latitudinal limits of approximately 30° North and South. Gautier (1992b) included Uruguay as part of the native range and USA populations as introduced, neither being confirmed in later studies.
