AI-generated Description

Oldenlandia corymbosa is an annual herb native to tropical Asia and Africa. In Qatar, it has been found to grow in moist areas, such as near water sources and in shaded regions. The plant is characterized by its small size, typically reaching 10-30 cm in height, with opposite leaves and small white or pinkish flowers arranged in corymbs (flat-topped clusters). Studies in Qatar have reported the presence of O. corymbosa in various locations, including Al Wakra, Dukhan, and the Qatar University campus, often in association with other weed species. The plant's adaptability to Qatar's arid climate suggests its potential as a resilient and potentially invasive species in the region.
