Basic Description:

This species is a sprawling to erect annual herb, typically reaching heights between 0.5 to 1 meter. It features divaricate branching and becomes woody at the base. The stems are slightly ridged and densely hairy. Leaves are obovate, measuring 2–6 cm in length and 6–20 mm in width, with 10–18 pairs of acute teeth. The leaf lamina is glabrous to sparsely hairy and gland-dotted, attached via petioles. The plant produces showy purple flower clusters approximately 3 cm wide, which are both distinctive and ornamental.

Distribution and Habitat:

Centratherum punctatum is native to South America, particularly southern tropical regions. It thrives in seasonally dry tropical biomes and has been introduced to various parts of the world, including the Philippines and Australia. In some regions, it has naturalized and become invasive, such as in Hawaii and certain Pacific Islands.

Medicinal Properties:

While Centratherum punctatum is noted for its ornamental value, specific medicinal properties are not extensively documented in the provided sources. However, recently it has been used in studies which have shown that leaf extracts exhibit antimicrobial, antioxidant and anti-proliferative properties and suggest that this species might be used a potential medicinal agent. Similarly in Nigeria, a research group has shown that essential oils extracted from C. punctatum may also have antimicrobial properties.

Known Toxicity:

There is limited information regarding the toxicity of Centratherum punctatum. As with many plants, especially those introduced to non-native regions, it's advisable to handle with care and consult local guidelines or experts when considering medicinal or culinary uses.

Additional Information:

Centratherum punctatum is valued for its ornamental appeal, often cultivated in gardens for its attractive purple flowers. However, due to its potential invasiveness, as observed in regions like Hawaii, caution is recommended when introducing it to new environments. The plant's adaptability to various climates underscores the importance of monitoring its spread to prevent ecological imbalances.
