Note: This species was proposed under the name Gracilaria ? eucheumoides, without a description, by Harvey in his Friendly Island exsiccata (1857b: no. 35). The specific epithet is derived from the generic name Eucheuma, which most authors treat as neuter even though J. Agardh treated it as feminine when establishing the genus. When treated as neuter (as in this catalogue), the stem is -mat rather than -m.
