<paragraph pageId="22" pageNumber="23">The colony is bottlebrush in shape (Figure 3e), the holotype measuring 26 cm tall and 12-13 cm in maximum diameter, having a basal branch diameter of 2.5 mm. The branching is sympodial, the branching formula being consistently 1/3L. The orthostiche interval is 12-18 mm. The length of the internodes of the branchlets ranges from 4.0-5.9 mm, up to nine nodes occurring on each branchlet; each internode supports one polyp. The polyps are about 1.1 mm in length, cylindrical (Figures 14a, b), and when preserved in alcohol tend to curve toward the branch surface, the tentacles often adhering to the surface branch. The axis is bronze in color.</paragraph>

The body wall sclerites (Figure 14
|
||
<normalizedToken originalValue="a–c">a-c</normalizedToken>
|
||
) are slightly flattened, rotund rods 0.22-0.25 mm in length, having a L:W of 5-6. They are straight and longitudinally oriented. The tentacular sclerites (Figure 14d) are similarly shaped rods, but are slightly shorter (0.18-0.22 mm in length) and more elongate (L:W = 5-8), also longitudinally oriented along the tentacles. All of the rods bear low sparse granulation. The pinnular scales (Figure 14e) are 0.08-0.12 mm in length, about 0.005 mm in thickness, and have a L:W of 3.5-4.5. The coenenchymal scales (Figures 14a, f) are 0.13-0.17 mm in length, about 0.01 mm in thickness, and have a H:W of 3.5-5.0. They are longitudinally oriented along the branch axis.
