| description | In this paper, <i>Sedum yongkangense</i> is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. Morphological analysis indicates <i>S. yongkangense</i> should be classified in the genus <i>Sedum</i> L. sect. <i>Sedum</i> and is distinct from the related species <i>S. ryukyuense</i>, <i>S. mukojimense</i> and <i>S. boninense</i> in having the morphology of a biennial life form; spreading cymes with numerous flowers; unequal, linear, terete sepals; horizontally spreading follicles; and an inland habitat. Molecular analysis of sequences of the nuclear ribosomal internal transcribed spacer (ITS) also demonstrates that <i>S. yongkangense</i> has a highest similarity of only 87.21% with any known species. Phylogenetic analyses indicate that <i>S. yongkangense</i> should be closely related to <i>S. bulbiferum</i>, but the latter differs in having the morphology of a perennial life form; a congested fertile stem; axillary bulbils of leaves; a spatulate-oblanceolate and flat leaf blade; lanceolate to oblanceolate and flat sepals; and deep yellow anthers and spreading follicles. |
