General Environment
This is a marine species.

Description
Plants single or in aggregates of 2–4, ranging from 3 to 26 cm in length, erect from a digitate, fibrous holdfast, and composed of sim- ple to sparingly ramified, slightly annulate stalks to 18 cm in length and 2.5 mm in width giving rise distally to single blades of spongy consistency to 2 mm in thickness, 18 cm in length, and 12 cm in width. Mature blades consisting of a dense reticulum composed of up to four orders of laterals, the laterals arising oppositely on suc- cessive bearing cells of costae and lower-order branches, those of the first and second orders distally curving toward and densely spreading over just one (the ‘ventral’) surface, terminal cells infre- quently terminating in tenaculae that attach to lateral surfaces of contiguous cells, the tenacular cells at times becoming laterally positioned due to continued subapical elongation of the bearing cell. First-order laterals on ‘dorsal’ surfaces not covered by higher-order laterals, appearing as evenly spaced, prominent costae. Cell divi- sions in primary axes and all branch orders segregative.

ETYMOLOGY: ‘The thoracic Struvea’, named for the rib-caged construction of the fronds, with their dorsally exposed primary-axial ‘vertebrae’ and regularly spaced series of paired costae (‘ribs’) that curve ventrally to enclose the ‘visceral’ higher orders of branching.
