Haeckel, 1887
In proximal 1/4th spicules with quadrangular latticed plates of thin, compressed bars. At first bars form 4 large pores around each spicule, subsequent development of bars forms 8 coronal pores around aspinal ones. Both aspinal and coronal pores may be further divided by additional growth of bars within them. Growth of latticed plates may be asynchronous on different spicules. Leaf-star large, occupying almost entire central capsule. Spicule length: 0.32-0.40 mm; latticed plates: 0.09 by 0.09 mm; leaf-cross: 0.04 mm.
