广西维管植物5新记录属

摘要:报道了广西维管植物5个新记录属、种,即双角草属(Diodia L.)、伏金腰箭属(Calyptocarpus Less.)、兔儿伞属(Syneilesis Maxim.)、凤头黍属(Acroceras Stapf)和落芒草属(Piptatherum P. Beauv.),以及隶属于该5属的双角草(Diodia virginiana L.)、金腰箭舅(Calyptocarpus vialis Less.)、兔儿伞[Syneilesis aconitifolia (Bunge) Maxim.]、山鸡谷草[Acroceras tonkinense (Balansa) C. E. Hubbard ex Bor]和钝颖落芒草(Piptatherum kuoi S. M. Phillips & Z. L. Wu)。其中双角草和金腰箭舅为归化种,文中提供了2个新归化种的形态描述和照片,并对其入侵性给予了评估;兔儿伞、山鸡谷草和钝颖落芒草为本土植物,提供其特征集要描述和照片,并对其生物地理学意义进行了讨论。

英文摘要:Five newly recorded genera of vascular plants in Guangxi are 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 L. and Calyptocarpus vialis Less. are naturalized species. The morphological descriptions and photos of two newly naturalized species are provided, and their invasiveness is evaluated based on wild investigation in Guangxi. As native plants, Syneilesis aconitifolia (Bunge) Maxim., Acroceras. tonkinense (Balansa) C. E. Hubbard ex Bor and Piptatherum. kuoi S. M. Phillips & Z. L. Wu are provided with the descriptions of characteristic diagnosis and photos. At last, the biogeographic significance for these newly recorded genera is discussed.
