Abstract:

On the basis of molecular phylogenetic analyses of the Persea group (Lauraceae) using the sequences of ITS and LEAFY intron II, the species Phoebe chinensis Chun, P.minutiflora H. W. Li, P.faberi (Hemsl.) Chun, P.microphylla H. W. Li and P.forrestii W. W. Smith, which are characterised by the persistent perianth lobes loosely clasping the base of fruit, apex extrorse, as well as globose fruit, were transferred into the genus Machilis. Accordingly, a new name Machilus montana L. Li, J. Li & H. W. Li, as well as three new combinations M.minutiflora (H. W. Li) L. Li, J. Li & H. W. Li, M.microphylla (H. W. Li) L. Li, J. Li & H. W. Li and M.forrestii (W. W. Smith) L. Li, J. Li & H. W. Li were reported here.

摘要：

根据分子系统学研究结果，楠属（Phoebe）中以其宿存的花被片在果时松散、先端外倾，果实球形为特征的物种，即山楠 Phoebe chinensis Chun，小花楠 P.minutiflora H. W. Li，竹叶楠P.faberi (Hemsl.) Chun，小叶楠P.microphylla H. W. Li 以及长毛楠P.forrestii W. W. Smith均应归入润楠属（Machilus），其中原先作为润楠属物种发表的竹叶润楠Machilus faberi Hemsl. 应予采用，但山楠一种其种加词发表时已是晚出同名，另起新名为Machilus montana L. Li, J. Li & H. W. Li, nom. nov, 而余下三种作为新组合在此发表，即：M.minutiflora (H. W. Li) L. Li, J. Li & H. W. Li, comb. nov.; M.microphylla (H. W. Li) L. Li, J. Li & H. W. Li, comb. nov.及M.forrestii (W. W. Smith) L. Li, J. Li & H. W. Li, comb. nov.。
