Abstract

This electron microscopy study of Achnanthes brevipes from mineralized tributaries (Solyanka, Chernavka, Khara) of the hyperhaline Lake Elton (Volgograd Region) provides new data on the variability of quantitative diagnostic characteristics (valve length, number of striae and areolae in 10 μm). Based on the original and published data, a refined diagnosis of A. brevipes is proposed. It is very similar to A. longipes in valve shape and quantitative characteristics, but striae are multi-row in the latter species and single-row in A. brevipes. A short note about the nomenclature status of A. brevipes is given.

短叶Achnanthes brevipes(硅藻门)形态的新资料

这项对埃尔顿湖（伏尔加格勒地区）高盐湖矿化支流（Solyanka、Chernavka、Khara）Achnanthes shortipes的电子显微镜研究为定量诊断特征（瓣膜长度、10μm内的条纹和乳晕数量）的可变性提供了新的数据。根据原始和已发表的数据，提出了一种精确的诊断短双歧杆菌的方法。它在瓣状和数量特征上与A.longipes非常相似，但后者的条纹是多排的，短A.shortipes的条纹是单行的。简要介绍了A.brevipes的命名状况。
