Primary axes 0.5–1.5 mm diam., with subopposite to alternate basally slightly tapering or unconstricted lateral indeterminate branches, these giving the thallus a pyramidal outline. All branches with sparse to numerous short spines. Branch primordia rounded, not associated with a spine, the spines arising at apices as the branch matures.

Reproduction. Reproductive structures not observed.

Distribution. Warmer waters of the Indian Ocean and western Atlantic.
