摘要: 报道了采自中国大兴安岭地区的中心类及无壳缝类硅藻植物5属9种,其中含3个中国新记录种:正链藻属的角状正链藻Orthoseira roeseana (Rabenhorst) O'Meara、脆杆藻属的古拉德脆杆藻Fragilaria goulardii (Brébisson) Lange-Bertalot和菱形脆杆藻Fragilaria nitzschioides Grunow。对国内文献报道较少的正链藻属、假十字形藻属、类十字形藻属、十字形藻属植物的形态特征进行了描述;对9种硅藻植物的分类特征及生态分布特点进行了描述。Abstract: Five genera and nine taxa of centric and araphid diatoms were investigated from the Great Xing'an Mts. Three taxa belonging to two genera were newly recorded in China: Orthoseira roeseana (Rabenhorst) O'Meara, Fragilaria goulardii (Brébisson) Lange-Bertalot, and Fragilaria nitzschioides Grunow. Chinese descriptions of Orthoseira Thwaites, Pseudos-taurosira Williams & Round, Staurosirella Williams & Round and Staurosira (Ehrenberg) Williams & Round are provided in this paper, with few previous record from China. Detailed descriptions of the taxonomical and ecological features of the nine taxa are also provided here.
