Precise date of publication1801 (more precise date not determined) The requirements for valid publication are specified in the ICBN (International Code of Botanical Nomenclature).
The nomenclature associated with the name Nullipora is rather complicated. Lamarck (1801: 374) established Nullipora for four species but did not designate a type. Woelkerling & Irvine (1986: 66-67) determined, however, that Nullipora nodulosa Lamarck, one of the four species originally included by Lamarck, is a superfluous substitute name (ICBN Art 52) for Millepora polymorpha Linnaeus (1767: 1285). Lamarck (1801) listed Millepora polymorpha in the synonymy of Nullipora nodulosa and also cited the illustration published by Ellis (1755, Tab. 27, Fig. C, as Corallium pumilum album Ellis) that is now the lectotype of Millepora polymorpha (see Spencer et al. 2009: 253; also see comments below).
The earlier generic name Apora Gunnerus (1768) (see AlgaeBase entry for Apora) also is typified by the type of Millepora polymorpha Linnaeus and thus the generic name Apora has nomenclatural priority (ICBN Art 11.3) over Nullipora. As a result, Nullipora is a superfluous substitute name (ICBN Art 52) for Apora, and the type of Apora also is the type of Nullipora (ICBN Art. 7.5). Bosc (1803a: 496; 1803b: 564) also had cited Millepora polymorpha Linnaeus as the type species of Nullipora,but without formally making the combination Nullipora polymorpha.
Apora (Gunnerus 1768), in turn, is a formally rejected name in favour of Phymatolithon Foslie (1898), which is formally conserved under ICBN Art. 14. Phymatolithon, also typified by the type of Millepora polymorpha, is listed in the Nomina Generica Conservanda (ICBN Appendix III, A9), and in accordance with ICBN Art. 14.4, Phymatolithon is conserved against all other generic names based on the same type, including Nullipora.
Millepora polymorpha Linnaeus is itself a superfluous substitute name for Millepora calcarea Pallas (1766: 265) and thus is illegitimate under ICBN Art. 52 (see Woelkerling & Irvine 1986 for further information). Consequently, Millepora polymorpha is automatically typified (ICBN Art. 7.5) by the type of M. calcarea, the name that ought to have been adopted under the rules.The end result is that the type of M. calcarea is also the type of M. polymorpha and of Nullipora nodulosa, and thus typifies Nullipora (ICBN Art. 10.1)..
The current correct name (see ICBN Appendix VII for definition of a correct name) for Millepora calcarea is Phymatolithon calcareum (Pallas) Adey & McKibbin (1970: 100). For further information, see the AlgaeBase entry for Phymatolithon.
Description: No description is provided as this name is currently in synonymy.
Changes in the ICBN necessitated an update (Spencer et al. 2009: 253) to the original typification (Woelkerling & Irvine 1986 58) of Millepora calcarea; the species is now lectotypified by an illustration (Ellis 1755, Tab. 27, Fig. C) cited in the protologue (Pallas 1766: 265) and epitypified by BM 000562555 (Algal Box Collection 1626) housed in the Natural History Museum , London. Further information is provided in the AlgaeBase entry for Phymatolithon.
Numbers of names and species: There are 31 species names in the database at present, of which 10 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
