Ipomoea eriocarpa R.Br.

Ipomoea eriocarpa is an annual herb belonging to the Convolvulaceae family, commonly known as morningglory. Native to regions across Africa, Asia, and parts of the Pacific, it is characterized by its twining or prostrate stems and showy funnel-shaped flowers. The species is adaptable to a range of habitats and is often found in disturbed environments such as croplands and fallows. It is used for both food and medicinal purposes in some local communities.
Description
Ipomoea eriocarpa is an annual herb with stems that can be either twining or prostrate, reaching up to 2 meters in length. The stems are pubescent or hispid. Leaves are petiolate, ranging from 2.5 to 8 cm in length and 0.8 to 5 cm in width, with an ovate to narrowly oblong shape. The base of the leaves is typically subhastate with rounded auricles, and the apex is acute. Both surfaces of the leaves are pilose to glabrescent, with petioles measuring 1 to 6 cm in length. The inflorescence consists of axillary subsessile or shortly pedunculate compact cymes, with peduncles up to 15 mm long. Bracteoles are linear, and pedicels measure 2 to 5 mm. The sepals are subequal, 8 to 9 mm long and 3 to 4 mm wide, ovate and acuminate, hispid-pilose, and spread out in fruit. The corolla is 6 to 9 mm long, narrowly funnel-shaped, and colored white, pink, or mauve, with a hirsute texture and a limb approximately 1.5 cm in diameter. The capsules are globose, 5 to 7 mm in diameter, pubescent, and often enclosed by the calyx. The seeds are 2.5 mm in size, black, glabrous, and punctate.
Habitat
Ipomoea eriocarpa is commonly found in wooded savannahs, croplands, and fallows. It thrives in disturbed environments and is well adapted to a variety of ecological conditions, including those with seasonal rainfall and varying soil types. Its presence in these habitats suggests a preference for open, sunny areas with some degree of human activity or disturbance.
Cultivation
While not widely cultivated, Ipomoea eriocarpa can be grown in warm, tropical to subtropical climates. It prefers well-drained soils and full sun. The plant is relatively easy to propagate from seeds, which should be sown in the spring after the last frost. Regular watering is necessary during the growing season, but the plant is somewhat drought-tolerant once established. Due to its climbing or prostrate growth habit, it may require some form of support or space to spread.
Uses
Ipomoea eriocarpa is used for both food and medicinal purposes in some local communities. In Angola, it is known as 'katata (kb)' and is utilized in traditional food and medicine. The plant's adaptability and availability in disturbed habitats make it a valuable resource in regions where it is native.
