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