Taxonomic notes: The status of the genus Omphalolappula is largely determined by the delimitation of the 2 mainly north temperate genera Hackelia Opiz and Lappula Moench as the fruits in all 3 genera are very similar in spite of the inference by Brand (1931) in the name of the above genus. Airy Shaw (1972), 'A dictionary of the flowering plants and ferns' as well as recent American literature maintained the latter 2 genera, while Chater (1972), Fl. Europaea 3:117, includes Hackelia in the synonomy of Lappula. I. M. Johnston (pers. comm. in Ising (1965), Trans. R. Soc. S. Aust. 89:283) considered Omphalolappula concava to be a species of Lappula, which (cf. I. M. Johnston (1927), Contr. Gray Herb. 78:5, 25) is probably because the whole inside keel of the mericarps is fused to the gynobase (the central axis to which the mericarps are attached and which consists of tissues of the gynoecium as well as of the receptacle). Lappula species are also like O. concava usually annuals whereas Hackelia species are perennials or biennials. Omphalolappula is here treated as a separate genus as it has always recurved fruiting pedicels atypical of Lappula and characteristic of Hackella (see also Embadium).
