摘要
本文报道了中国西南横断山区一个高山湖泊中的一个新物种,即悬铃木属(Cymbella C.a.Agardh)。本文对该新种罗玉兰Cymbella looyulane sp.nov.进行了详细的形态学描述;该描述基于光和扫描电子显微镜。罗玉兰的主要特征是在近端附近具有强烈反向的中缝外侧分支的强背中央瓣,一个大的中心区域占据了瓣宽度的大约一半,并且狭缝状乳晕包括可能不可变或部分双列的条纹。该新种的形态特征类似于黑海松(C.heihainensis Y.Li et Gong)、莫迪切蓬塔(C.modicepunctata Krammer)和亚洲松(C.asiatica Metzeltin)、兰格·贝塔洛(Lange Bertalot)和李(Y.Li),但在大小、瓣膜形状、条纹密度、中心面积和柱头数量等方面与这三种不同。
One new species of Cymbella C.A. Agardh (Bacillariophyta) from high altitude lakes in the Hengduan Mountains of Southwest China
This paper describes a new species of the genus Cymbella C.A. Agardh from an alpine lake in the Hengduan Mountains of southwestern China. A detailed morphological description of the new species, named Cymbella luoyulanae sp. nov., is presented; the description is based on light and
scanning electron microscopy. The main features of C. luoyulanae are strongly dorsiventral valves with strongly reverse-lateral raphe branches near the proximal ends, a large central area occupying approximately a half of the width with the valve and slit-like areolae comprising striae that may be unseriate or partially biseriate. The new species has morphological characteristics that resemble those of C. heihainensis Y.Li et Gong, C. modicepunctata Krammer and C. asiatica Metzeltin, Lange-Bertalot et Y.Li, but it differs from these three species in details of size, valve shape, striae density, central area, and number of stigmata.
期刊介绍:
The interest of the journal is field (terrestrial and aquatic) and experimental botany (including microorganisms, plant viruses, bacteria, unicellular algae), from subcellular level to ecosystems. The attention of the Journal is aimed to the research of karstic areas of the southern Europe, karstic waters and the Adriatic Sea (Mediterranean).
