Many species of Portulaca L. (Portulacaceae) pose a significant risk of spreading in agroecosystems as weeds. Contamination of agricultural products by these plants may significantly impact international trade. Effective prevention should be based on the knowledge of their botanical names. This research aimed to study the diversity and morphology of the genus Portulaca by surveying plants in agroecosystems and related distribution areas, collecting samples, recording morphological data, and identifying the collected specimens. A total of
25 plant samples were collected, and 7 species were identified based on morphological characteristics: P. amilis Speg., P. grandiflora Hook., P. oleracea L., P. pilosa L., P. quadrifida L., P. umbraticola Kunth, and Portulaca sp. The study found that P. amilis and P. umbraticola have never been previously reported in Thailand. The distribution of P. oleracea, P. pilosa, P. quadrifida and Portulaca sp. showed their status as weeds in agricultural areas that should be monitored. Meanwhile, P. amilis, P. grandiflora and P. umbraticola were mostly found as ornamental plants in community areas. All plants found can serve as a reference database for plant protection and development in the future.
