ITS and ETS-based sequence analyses of 29 Neolitsea, six Actinodaphne and five outgroup `core' Laureae taxa show that Neolitsea is monophyletic with two large subclades, whereas most of the sampled Actinodaphne are paraphyletic below it. Inflorescence features appear to be among the more reliable morphological characters for explaining relationships between Neolitsea and other genera within the `core' Laureae, with the Neolitsea/Actinodaphne clade defined by inflorescences lacking vegetative terminal buds in the main axis. Although the relationships within Neolitsea are still poorly resolved, there is enough structure to suggest that the genus seems to divide into two groups based on fruit shape: elliptic or ovoid, versus globose, although more evidence (both molecular and morphological) and wider taxon sampling are required to confirm this.
