Data from: Dianyuea gen. nov. (Salicaceae: Scyphostegioideae) from southwestern China

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.Dianyuea turbinata_matKDianyuea turbinata maturase K (matK) gene, partial cds; chloroplastDianyuea turbinata_rbcLDianyuea turbinata ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL) gene, partial cds; chloroplastDianyuea turbinata_trnH-LDianyuea turbinata trnL-trnF intergenic spacer, partial sequence; chloroplastMATK-F.1392427.C05MatK original sequence data, forwardMATK-R.1392428.C06MatK original sequence data, reverseRBCL-F.1392429.C07rbcL original sequence data, forwardRBCL-R.1392430.C08MatK original sequence data, reverseTRNL-F.YP01513957.E05trnL-trnF original sequence data, forwardTRNL-R.YP01513958.E06trnL-trnF original sequence data, revers
