从苏格兰的洛赫列文湖采集的水样中含有单细胞中心硅藻，其中以一种我们称为汉茨奇Stephanodiscus格鲁诺的分类群为主。它以几种形态型存在，并与S.来自Rabenhorst exsiccata 1104的hantzschii还简要描述了实验性营养强化材料的形态特征。两个非常不同的形态型和额外的三个形态型，或多或少的瓣膜模式的恒定功能已被区分。此外，半球形阀的存在使得描述这种非常常见的中心硅藻的生活史阶段成为可能，并对S。Hantzschii给出。
Water samples taken from Loch Leven, Scotland, contained unicellular centric diatoms dominated by a taxon we called Stephanodiscus hantzschii Grunow. It existed as several morphotypes, and these are described and compared with the type material of S. hantzschii from the Rabenhorst exsiccata 1104. The morphological features of material subjected to experimental nutrient enrichment are also briefly described. Two very distinct morphotypes and an additional three morphotypes, with more or less constant features of valve pattern have been distinguished. In addition, the presence of hemispherical valves made it possible to describe stages in the life cycle of this very common centric diatom, and an amended description of S. hantzschii is given.
