If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|W. Hantzschel 1975||Honeycomblike network regular hexagonal polygons; may be also 4- to 8-sided; reticulate pattern of considerably varying size (incomplete along margins) but diameter of meshes constant within individual net (from less than 1 mm to about 50 mm); walls of meshes 0.5 to 2 mm wide and occasionally consisting of small circular or oval “pimples” closely arranged in rows which may cross large areas up to about 1 sq m; polygons sometimes elongate due to current action.|
