Note: The binomial Laurencia intricata, published without a description by Lamouroux, was considered to be invalid by P. Silva, Meñez, & Moe (1987: 66), who employed the taxonomic synonym Laurencia implicata J. Agardh (1852 [1851–1863]: 745; type locality: St. Croix, Virgin Islands). However, according to Art. 44.2, for names of non-vascular plants published before 1 Jan. 1908, an illustration, such as that provided by Lamouroux, is sufficient for valid publication.
