A modern protologue of the name of a new plant taxon: Orychophragmus violaceus var. odontopetalus Ling Wang & Chuan P. Yang, from a paper in volume 22 of the journal Novon by Wang & al. (2012: 110). Reproduced by permission of Missouri Botanical Garden Press. Components of the protologue are as follows: Name cited in full (generic name not abbreviated), authorship explicitly cited, and novel status indicated (“var. nov.”); all three items are best practice and should certainly be followed (even if strictly they are not requirements for valid publication under the Code).Citation of type (Art. 40.1), which is a specimen (X.J. Ma, L. Wang & C.P. Yang 09009; Art. 40.4), using one of the words “typus” or “holotypus”, or its abbreviation, or its modern-language equivalent (here both words in English; Art. 40.6), and specifying the single herbarium where it is conserved (NEFI; Art. 40.7).Latin or English validating description or diagnosis (here a Latin diagnosis and an English description), as required for names published from 2012 onward (Art. 39.2).Notes on habitat and distribution, IUCN Red List category, and citation of paratypes (Art. 9.7).
