Abstract

We collected an unusual new plant of Phoebe (Lauraceae) from southeastern Yunnan, China, which possesses more or less oblong leaves, paniculate inflorescences with strictly opposite lateral cymes, trimerous flowers with 4-locular stamens, and large fruits with tiny, equal, persistent tepals. Our molecular phylogenetic study based on nrITS, LEAFY and plastid matK sequences suggests that this species belongs to a clade of Phoebe including P. puwenensis, P. megacalyx, and P. macrocarpa. However, this species differs from the latter three species by subglabrous twigs, leaves and inflorescences (vs. pubescent twigs, leaves and inflorescences in the latter three species), larger fruits (5–8 cm long vs. 1–4 cm long in the latter three species), and smaller tepals (1–2.5 mm long vs. 5–15 mm long in the latter two species). As a result, Phoebe jinpingensis sp. nov. is described and illustrated here as new to science.
