This article reviews current knowledge of wall morphogenesis in pennate diatoms in relation to the way characters are defined and described for taxonomic and systematic analyses. It argues that an understanding of ontogeny is essential for the accurate identification of character homologies, which in turn must underpin all phylogenetic and systematic analyses. Terminology should reflect character homology, but most diatom terminology fails to do this, with concomitant confusion and potential taxonomic mistakes. Identifying where information is lacking or misinterpreted are first steps toward improving our understanding of diatom structure and relationships. After reviewing the current knowledge on pennate diatom structure and its development, this article briefly discusses the significance of morphological variation, character polarity, and the vital importance of applying diatom terminology correctly.
本文回顾了有关羽纹硅藻细胞壁形态发生的当前知识，以及这些知识与分类学和系统分析中特征定义和描述方式的关系。文章认为，对个体发育的理解对于准确识别特征同源性至关重要，而这反过来又必须支撑所有的系统发育和系统分析。术语应该反映特征同源性，但大多数硅藻术语未能做到这一点，从而导致混淆和潜在的分类错误。识别信息缺乏或误解的地方是提高我们对硅藻结构和关系理解的第一步。在回顾了关于羽纹硅藻结构及其发育的当前知识后，本文简要讨论了形态变异、特征极性的重要性，以及正确应用硅藻术语的至关重要性。
