basionym: Stratiotes acoroides L.f. legitimate

• Comment: Combination indicated by Royle in text on p. 377 via his citation of "Enhalus (Stratiotes acoroides, Linn. F.)..." but this does not constitute definite association of the genus name Enhalus with the specific epithet as required under ICN 35.2 (Shenzhen Code, 2018) . The combination is made in the index on p. 453 via indirect reference to the basionym.

• Comment: Steudel attributes this name to "Rich.". This may be in reference to L.C.M.Richard, Mém. Cl. Sci. Math. Inst. France 1811(2): 65 (1814), where Richard states that his new genus Enhalus was comprised of Stratiotes acoroides L.f., but did not definitely associate the genus name Enhalus with the specific epithet as required under ICN Art. 35.2 (Shenzhen Code, 2018).
