2.4.1. New combinations in Actinodaphne

Actinodaphne Nees and Neolitsea (Benth. & Hook.f.) Merr. are two closely related genera.Although the results of phylogenetic ( Li et al. 2007, 2008) and phylogenomic studies ( Song et al. 2019) indicate that Neolitsea may be nested within Actinodaphne , these studies were based on limited taxon sampling, especially with regards to Malesian species. Notably, other studies with denser sampling of Malesian species have retrieved a sister-relationship between the two genera ( Fijridiyanto & Murakami 2009a, b). Irrespective of the exact phylogenetic relationships in the Actinodaphne – Neolitsea group, the results of a study by Li et al. (2008) and our own observations suggest that Malesian Neolitsea species can be distinguished from Actinodaphne by usually having tripliveined (vs always pinnately veined) leaves that are alternate and clustered (vs (sub-)verticillate), decussate and persistent involucral bracts (vs imbricate and caducous), and dimerous (vs trimerous) flowers. Unfortunately, relationships in the Litsea group remain unresolved so that a final word on the generic boundaries and characters in the Actinodaphne – Neolitsea group is not in sight at present. We therefore propose several new combinations in Actinodaphne of Philippine species originally described under Neolitsea . Should Neolitsea eventually be sunk into an expanded Actinodaphne , then these new combinations will remain, since the latter name has priority over the former.
