广西植物新资料

广西涠洲岛是中国第一大火山岛,现为国家级海洋公园。经过两次的实地调查,采集到标本共348号。整理后发现:2个新记录属,即细穗草属(Lepturus)和蒭雷草属(Thuarea);6个新记录种,即疏花木蓝(Indigofera colutea)、滨豇豆(Vigna marina)、留萼木(Blachia pentzii)、滨海白绒草(Leucas chinensis)、细穗草(Lepturus repens)、蒭雷草(Thuarea involuta)。这些都是适应沿海生境的种类。这些新记录种的发现不仅丰富了广西的植物多样性资料,而且为沿海地区的生态修复提供了参考。

Some new records from Guangxi

Weizhou Island, a national marine park, is the biggest volcanic island in China. The plants of Weizhou Island have been investigated by the Third Institute of Oceanography, State Oceanic Administration and Xiamen University twice in 2016 and 2017. In total, 348 herbarium specimens were collected. From these collections two genera(Lepturus and Thuarea)and six species from across four families were identified as new records to Guangxi(Indigofera colutea, Vigna marina, Blachia pentzii, Leucas chinensis, Lepturus repens and Thuarea involuta). All these species are adapted to the coastal habitat. These new records not only enriched the data of plant diversity of Guangxi, but also provide a useful reference for ecological remediation of coastal areas.
