Remarks For synonymy and a description, refer to Schuchert (1997). In the present material, the lateral nematothecae associated to the cauline hydrothecae on the side opposite to the cladial apophyses are often absent (Fig. 14O); in only rare instances, a pair is formed (Fig. 14P). The cladia display a regular structure: they begin with a short, quadrangular, athecate segment, followed by an ahydrothecate internode bearing a superior nematotheca and ending distally in an oblique node; afterwards, the segmentation is heteromerous, with up to 8 hydrothecate internode alternating with ahydrothecate counterparts (Fig. 14N); the latter are short, delimited proximally by a transverse node and distally by an oblique node, and bear a frontal nematotheca; the hydrothecate internodes are slightly longer, are delimited proximally by an oblique node and distally by a transverse one, and bear distally a hydrotheca and its 4 associated nematothecae: a mesial, a pair of laterals, and a scale-shaped axillar one. There is an important sexual dimorphism of the gonothecae: the female, given off from below the cauline hydrothecae, are large, ovoid and bear proximally 3 nematothecae (Fig. 15D); the male gonothecae, borne on cladia, are comparatively minute, and bear a single basal gonotheca (Fig. 15E).
