报道采自新疆及内蒙古地区的菱板藻属(硅藻门)中国新纪录植物7种,分别为丰富菱板藻(Hantzschia abundans Lange-Bertalot)、喜碱菱板藻(Halkaliphila Lange-Bertalot)、巴克豪森菱板藻(H.barckhausenii Lange—Bertalot&Metzeltin)、较长菱板藻(HlongaLange—Bertalot)、仿密集菱板藻(Hparaeompaeta Lange—Bertalot)、美丽菱板藻(Hspectabilis(Ehrenberg)Hustedt)和近活跃菱板藻(Hsubvivacior Lange—Bertalot)。对其分类学特征进行了详细的描述,并给出了光镜或扫描电镜照片以及生境特征等,为该属种类的世界地理分布提供新资料。
Seven species of Hantzschia (Bacillariophyta) are first reported from ince in China. They are Hantzschia abundans Lange-Bertalot, H. alkaliphila Xinjiang and Neimeng' gu Prov- Lange-Bertalot, H. barckhausenii Lange-Bertalot & Metzehin, H. longa Lange-Bertalot, H. paracompacta Lange-Bertalot, H. spectabilis (Ehren- berg) Hustedt and H. subvivacior Lange-Bertalot. The taxonomic characteristics, LM (light microscope) or SEM (scanning electron microscope) photos and ecological affinities were described for each taxon. It will provide new data on the geographical distribution of this eenus.
