COMPARATIVE ANATOMY OF CHAROPHYTA: II. THE AXIAL NODAL COMPLEX—AN APPROACH TO THE TAXONOMY OF LAMPROTHAMNIUM12

摘要: SUMMARY The present investigation on the axial nodes of 32 taxa belonging to genera Chara, Lamprothamnium, Nitellopsis, Nitella and Tolypella confirms previous reports that within a given taxonomic group structure main nodal complex is highly consistent. Besides tribe Nitelleae, Lamprothamnium Chareae only genus in which central cells subdivide. This anatomical feature thus clearly separates from other chareae. In 2 controversial species C. hornemannii buckellii, study reveals their complexes do not The transfer these two by Daily (1) may be appropriate.
