PhytoKeys 140: 101–106. https://doi.org/10.3897/phytokeys.140.47664 Abstract Here Phoebe hekouensis Bing Liu, W.Y. Jin, L.N. Zhao & Y. Yang from south-eastern Yunnan Province of China is described as new to science. Tis species is morphologically similar to P. megacalyx H.W. Li in the twigs being robust and brownish tomentose, the ovary densely pubescent and the tepals longer than 1 cm, but difers from the latter species by the leaves being broader, up to 18 cm (vs. 4.5–11.5 cm), the inforescences shorter, ca. 10–15 cm long (vs. up to 23 cm), the ovary completely and densely pubescent (vs. pubescent only at the apical portion) and the stigma conspicuous (vs. inconspicuous). Te new spe- cies also resembles P. macrocarpa C.Y. Wu, but difers from the latter by the tepals being longer, 9–13 mm long (vs. ca. 4 mm). Keywords China, Lauraceae, Phoebe, taxonomy, Yunnan Introduction Te genus Phoebe Nees of the Lauraceae contains about 100 currently recognised species and is widely distributed in tropical and subtropical Asia (van der Werf 2001, Wei and van der Werf 2009). Members of this genus are usually trees, with pinnately-veined leaves usually obovate to oblanceolate and slightly clustered at the tips of branches and trimer- ous bisexual fowers with nine 4-loculed fertile stamens and persistent tepals clasping the * Tese authors contributed equally to the work.
