Abstract

Nomocharis aperta (Franchet) E. Wilson is a heterogeneous species including morphotypes with pink tepals bearing swellings on both sides of the inner tepal’s basal median channel and those with yellow tepals lacking swellings. Molecular phylogenetic and pair-wise distance analyses of nrITS and chloroplast psbA-trnH support recognition of the yellow-flowered morphotype lacking nectary processes as a new, separate species of Nomocharis. Here, we present the new species, Nomocharis gongshanensis Y. D. Gao et X. J. He sp. nov., and resolve its systematic position in the LiliumNomocharis complex using the ITS and psbA-trnH markers. Seven variant copies of ITS were isolated from N. gongshanensis. Maximum parsimony and Bayesian analyses placed the clones in two different Nomocharis clades, N. aperta + N. saluenensis and sect. Eunomocharis, suggesting a putative hybrid origin of the new species. The psbA-trnH sequence of N. gongshanensis is identical to that of N. saluenensis, indicating that the latter may be the maternal ancestor. Our analyses support the monophyly of LiliumNomocharis and mutual paraphyly of the two genera. Nomocharis was resolved within Lilium as sister to the European lilies of sect. Liriotypus (sensu İkinci). The 12 LiliumNomocharis clades recovered in this study are consistent with previous molecular studies but are incongruent with traditional circumscription of and subgeneric divisions within Lilium. These results highlight the need for taxonomic revision of Lilium to accommodate Nomocharis and reconsideration of the origin and evolution of Nomocharis.
