Our results indicated that Machilus is a monophyletic clade within the Persea group, and its persistent and spreading to reflexed tepals on fruit are an important character for its generic delimitation against the related genera Phoebe , Alseodaphne and Persea . This study rejects the former infrageneric systematic arrangement of Machilus based on the pubescence type of tepals abaxially and the size of fruit , but suggests that the type of inflorescences may be valuable for the understanding of its infrageneric evolution . However , the species relationships within Machilus are poorly resolved . Samplings of additional taxa from Machilus and more powerful markers are needed in further study .
