Basic Description:

Acalypha segetalis is an annual herb reaching up to 50 cm in height, often branching from the base with decumbent-ascending stems. The leaves are ovate, measuring 2–7 cm in length, with serrated margins. Inflorescences are typically less than 2.5 cm long, containing both male and female flowers. Female bracts per inflorescence number between 1 and 3, with crenate margins. The male portion is pedunculate, often exhibiting reddish flowers.

Distribution and Habitat:

Acalypha segetalis is widespread across tropical and southern Africa, including countries such as Nigeria, Ghana, and Ethiopia. It thrives in seasonally dry tropical biomes, commonly found in alluvial and black clay soils on floodplains, pans, moist grassy areas, rocky outcrops, and as a weed in cultivated and disturbed grounds. The species is adaptable to various habitats, often flourishing in miombo and mopane woodlands.

Medicinal Properties:

Information regarding the medicinal properties of Acalypha segetalis is limited. However, related species within the Acalypha genus are known for various traditional medicinal uses, such as treating skin conditions and respiratory issues. Further research is necessary to ascertain the specific medicinal applications of A. segetalis.

Known Toxicity:

There is no substantial evidence indicating significant toxicity associated with Acalypha segetalis. Nonetheless, as with many plants in the Euphorbiaceae family, some species contain irritant compounds. Caution is advised when handling plant material to avoid potential skin irritation.

Additional Information:

Acalypha segetalis is often compared to Acalypha indica due to morphological similarities but is distinguished by its more branched structure and shorter inflorescences. The plant's adaptability to various environments makes it a common component of the flora in its native range. Its role in local ecosystems includes serving as ground cover and contributing to the biodiversity of herbaceous plant communities.
