湖北黄芩属两个新记录种

Two new records of Scutellaria in Hubei Province

本文报道了湖北中医药植物资源调查过程中发现的黄芩属(Scutellaria)2个新记录种,柔弱黄芩(Scutellaria tenera C.Y.Wu et H.W.Li)与腺毛黄芩(Scutellaria fujianensis Z.H.Chen,W.Y.Xie et X.Z.Chen)。本文补充了腺毛黄芩种子的形态特征信息以及武汉居群中植株个体叶背呈深紫色的特征信息;在柔弱黄芩标本中,发现它与腺毛黄芩相似也有根茎。两种植物的发现进一步丰富了黄芩属在全国的分布格局和本属在湖北的种类,并为湖北地区的物种多样性研究提供了新的分布信息。

During the plant investigation of traditional Chinese medicine resources in Hubei Province,two new records of Scutellaria were found,including Scutellaria tenera C.Y.Wu et H.W.Li and S.fujianensis Z.H.Chen,W.Y.Xie et X.Z.Chen.The morphological characteristics of seed for S.fujianensis were supplemented.In Wuhan population,individuals of S.fujianensis are characterized by dark purple abaxial surface of leaves.In the specimens of S.tenera,we found they also have rhizomes similar to that of S.fujianensis.These discoveries further enrich the species of genus Scutellaria in Hubei and provide new distribution information for the study of plant diversity in Hubei Province.
