Remarks (internal):As now understood this genus is rather difficult to define since it has been necessary to incorporate with it such genera as Linderia and Anthurus, which are connected to Clathrus by a continuous series of intermediate states. At present Ileodictyon Tul. is excluded because of its total lack of dorsiventrality (see discussion p. 11) and the simplicity of its tubular construction. One reason for the difficulty in defining Clathrus probably is to be found in its position as the most primitive genus of the family, thus embracing the initial members of all the evolutionary series.
