Solanderia misakinensis (Inaba, 1892)

Colonies 40-50 mm high, arborescent, flabellate, stem and branches thick and woody, branches becoming progressively more slender with distance from basal stem, tips of branches long and thin. Skeleton a trabeculate meshwork, fibres running more or less parallel along younger branches but less orderly on older branches; openings subcircular, on older branches fibrous junctions often produced into minute clavate spines.

Hydranths numerous, large, emerging irregularly over entire colony without supporting hydrophores; body with three to five capitate tentacles surrounding hypostome and 12-20 other tentacles scattered over body.

Gonophores small, balloon-shaped, arising randomly on indistinct pedicel from branches.

Colour: Proximal stem dark brown, branches paler brown fading to pale buff at tips, hydranths and gonophores white.
