| Abstract: | By the help of this method the morphological -variability ofScenedesmus quadricauda during its ontogenesis was studied.During the life cycle the size and shape of the cells vary simultaneously.Some species described on the bases of these features are onlydifferent states of the same species. Genera of the subfamily Crucigenioideae (Scened-esmaceae) havebeen distinguished by very subjective and indistinct features.Examination of the course of their life cycles in the synchronizedcultures showed that only valuable feature for distinguishingthese genera is the mode of reproduction; the mode of orientationof autocoenobia in the mother coenobium. Two basic modes offormation of daughter coenobia were discovered. Based on thesecriteria it is possible to deduce all other types of this wholetaxonomical group. (Received November 24, 1962; ) |
