Data from: Dianyuea gen. nov. (Salicaceae: Scyphostegioideae) from southwestern China
Shang, Ce; Liao, Shuai; Guo, Yong-Jie; Zhang, Zhi-Xiang (2017), Data from: Dianyuea gen. nov. (Salicaceae: Scyphostegioideae) from southwestern China, Dryad, Dataset, https://doi.org/10.5061/dryad.b331s
Dianyuea C. Shang, S. Liao & Z. X. Zhang, a new monotypic genus of Salicaceae based on Flacourtia turbinata H. J. Dong & H. Peng, is described and illustrated. Morphologically, Dianyuea differs from Flacourtia Comm. ex L'Hér. by having six connate stamens, basal placentation and lobed seed appendages. All those features indicate that Dianyuea is allied with Scyphostegia Stapf. A molecular phylogenetic analysis using plastid trnL-F, matK, and rbcL sequence data for representatives of 16 genera in Salicaceae s.l. shows that Dianyuea is sister to Scyphostegia. The new combination Dianyuea turbinata (H. J. Dong & H. Peng) C. Shang, S. Liao & Z. X. Zhang is proposed.
