Diagnosis.
Colonies unbranched,
1.55–2.92 m
in height, showing a basal plate. Axis straight for 25 to 81% of the total length, then curving in regular, steep, well-defined spirals or sinuously. Distance covered by spirals (when defined)
9–57 cm
, spiral diameter
5–22 cm
; number of spirals 1 to 5.5. Axis diameter just above basal plate
3.7–9 mm
; at tip of colony
0.7–2 mm
. Polypar spines conical, laterally compressed, rounded at tip, forming a 90º angle with axis; showing small tubercles or protuberances. Size of spines 100 to 330 μm (individual colonies average 140–320 μm, n = 19 colonies). Distance between consecutive spines 310–930 μm. Small spines distributed irregularly between large spines, with no apparent pattern. Small spines conical, sharp, forming a 90º with axis, size 30–82 μm, with no tubercles or protuberances. Polyps white, transverse diameter about
2–3 mm
; sagittal diameter
1–2 mm
, arranged in multiple irregular rows, except in apical part of axis (apparently in a single row); one side of entire stem usually free of polyps. Sagittal tentacles about
1.3–2.15 mm
; lateral tentacles
1.05–1.45 mm
. Oral cone about 0.5–
0.07 mm
. (adapted from
Echeverría, 2002
