Sclerites from interior of peduncle. Scale: H-K = 0,15 mm. Sclerites are mostly small ovals, or elongate rods, usually 0,12 mm or less in length. They are present both in the rachis exterior and interior, as well as the peduncle exterior and interior. Some ovals may have a cross-pattern originating in the centre. Some sclerites of the rachis may be constricted in the middle with rounded or truncate ends. Sclerites are densely distributed, and are more or less consistent in shape throughout the colony. They vary from 0,02-0,13 mm in length. Autozooids may have a few scattered sclerites at the bases, extending up to less than one-third total length of polyp. The tentacles have many rod-like sclerites, 0,06 mm in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
