描述了接合过程中的desmid分类群Pleurotaenium ehrenbergium（Breb.）de Bary和梁木P. trabecula var. mediolaeve（Playf.）克里格异常接合，导致在单性孢子或三倍体孢子，也被描述和三重接合的过程进行了说明。本文还讨论了接合囊的确切性质，以及它与双星藻科和某些植物的接合管的相似性而非同源性。这表明，有两种方法的接合在盾皮类desermina和Pleurotaenium这里描述的事件的顺序可能是广泛的。Pleurotaenium接合孢子的两个独特的功能进行了描述，形态上不同的盖和乳头状中孢子。
The process of conjugation is described for the desmid taxa Pleurotaenium ehrenbergii (Breb.) de Bary and P. trabecula var. mediolaeve (Playf.) Krieger. Anomalous conjugations, resulting in parthenospores or triploid spores, are also described and the process of triple conjugation is illustrated. The exact nature of the conjugation vesicle, and its analogy but not homology with the conjugation tube of Zygnemaceae and some desmids, is discussed. It is suggested that there are two methods of conjugation in placoderm desmids and that the sequence of events described here for Pleurotaenium may be widespread. Two unique features of the Pleurotaenium zygospore are described, a morphologically-differented operculum and a mammillate mesospore.
