                 Abstract: Five newly recorded genera of vascular plants in Guangxi were reportedꎬ namelyꎬ Diodia L.ꎬ Calyptocarpus
                 Less.ꎬ Syneilesis Maxim.ꎬ Acroceras Stapf and Piptatherum P. Beauv.ꎬ as well as Diodia virginiana L.ꎬ Calyptocarpus
                 vialis Less.ꎬ Syneilesis aconitifolia ( Bunge) Maxim.ꎬ Acroceras tonkinense ( Balansa) C. E. Hubbard ex Bor and
                 Piptatherum kuoi S. M. Phillips & Z. L. Wu belonging to the five genera. Among themꎬ Diodia virginiana and
                 Calyptocarpus vialis are naturalized species. The morphological descriptions and photos of two newly naturalized species
                 were providedꎬ and their invasiveness was evaluated based on wild investigation in Guangxi. As native plantsꎬ Syneilesis
                 aconitifoliaꎬ Acroceras tonkinense and Piptatherum kuoi were provided with the descriptions of characteristic diagnosis and
                 photos. At lastꎬ the biogeographic significance for these newly recorded genera was discussed.
