title: Data from: Phylogeny and generic delimitation in Molluginaceae, new pigment data in Caryophyllales, and the new family Corbichoniaceae

description: The circumscription of Molluginaceae has changed radically in recent
 years, with Corbichonia being moved to Lophiocarpaceae, Limeum to
 Limeaceae, Macarthuria to Macarthuriaceae and all species of Hypertelis,
 except the type, to Kewa in Kewaceae. In a broad analysis of core
 Caryophyllales using plastid trnK-matK and rbcL sequences, the position of
 Molluginaceae in a strict sense as sister to the Portulacineae clade is
 corroborated, as are the positions of Corbichonia, Limeum and Kewa outside
 the family. The phylogeny of Molluginaceae is reconstructed based on
 trnK-matK and nuclear ITS sequences of about half of the currently
 recognized species in the family and with representatives from all
 recognized genera. Mollugo is found to be polyphyletic and a new taxonomy
 for the family with 11 genera is proposed. Mollugo in its new restricted
 sense is a mainly American genus of about 15 species, including M. ulei
 comb. nov., previously placed in the monotypic Glischrothamnus. The
 Australian and Asian genus Trigastrotheca is resurrected for T.
 molluginea, T. pentaphylla comb. nov. and T. stricta comb. nov. The name
 Paramollugo nom. nov. is proposed for the Mollugo nudicaulis group and the
 combinations P. angustifolia comb. nov., P. cuneifolia comb. nov., P.
 decandra comb. nov., P. deltoidea comb. nov., P. navassensis comb. nov.
 and P. nudicaulis comb. nov. are made. Hypertelis is expanded to include,
 besides the type H. spergulacea, also H. cerviana comb. nov., H. fragilis
 comb. nov., H. umbellata comb. nov. and H. walteri comb. nov. In
 Pharnaceum, the new combination P. namaquense comb. nov. is made,
 Hypertelis longifolia is treated as a synonym of P. lineare and Mollugo
 tenella as a synonym of P. subtile. Corbichonia is proposed to be treated
 as a family of its own, Corbichoniaceae fam. nov. Several names are
 lectotypified, including the Linnaean Mollugo pentaphylla and M. stricta.
 An anthocyanin is reported for the first time from Simmondsiaceae. The
 detection of anthocyanins in members of Kewaceae and Molluginaceae agree
 with previous reports and corroborate the view that these families
 represent reversals from betalains to anthocyanins. The report of an
 anthocyanin in Limeaceae, previously regarded as unpigmented, apparently
 represents a newly detected reversal from betalains to anthocyanins in
 this family.
