Daphniphyllum peltatum Yan Liu & T. Meng, a new species of Daphniphyllaceae from southwestern Guangxi, China, is described and illustrated. The new species is mainly similar to D. calycinum Benth. in the shape of leaf blade, lunate anthers, elliptic drupes and the length of infructescence, but it can be easily distinguished by blue green branchlets, peltate leaves, obviously raised midvein and lateral veins on both surfaces. We also provide a key to all species of Daphniphyllum in China, and a table to distinguish the new species from D. calycinum.
KEY WORDS: China, Daphniphyllaceae, Daphniphyllum peltatum, limestone flora, new taxa, southwestern Guangxi, taxonomy.
Daphniphyllum peltatum Yan Liu & T. Meng, sp. nov.
Diagnosis: Daphniphyllum peltatum is mainly similar to D. calycinum Benth. in the shape of leaf blade, lunate anthers, elliptic drupes and the length of infructescence, but can be easily distinguished from the latter by branchlets blue green (vs. grayish brown); base of leaf blade rounded, peltate (vs. base broadly cuneate, not peltate); pedicels of female flower 1-1.3 cm long (vs. 5-7 mm long); ovary ca. 3 mm long (vs. 1.5-2 mm long); drupe ca. 7 mm in diam. (vs. 3-6 mm in diam.).
Etymology: The specific epithet is derived from the peltate leaf of this new species. Chinese name is proposed here as “盾葉虎皮楠”.
