Sedum ichangensis Y. B. Wang, sp. nov.
Diagnosis: Sedum ichangensis has papillate carpels and appears to be morphologically similar to S. elatinoides and S. rosthornianum. It can be distinguished from S. elatinoides by its perennial habit (vs. annual) and solitary flower (vs. flowers in cymes) and from S. rosthornianum in its entire leaf margins (vs. leaf margins dentate), its branched stems (vs. stems simple) and its solitary flowers (vs. flowers in paniculiform cymes).
Distribution and habitat: Sedum ichangensis is known from Longzhouping town of Changyang County, Gufu town of Xingshan County and Muyang River of Yiling County in Yichang City of western Hubei Province, central China (Fig. 3). It grows on rocks of roadsides, especially in fissures filled with soil, at an elevation of ca. 100–280 m.
Etymology: The specific epithet of this new species is dedicated to the Yichang city.
Chinese name: Yi-chang-jing-tian (宜昌景天).
