Azorella, Mulinum, Huanaca, Schizeilema are not monophyletic, and Laretia could be embedded in a clade of Azorella. See Nicolas, A.N. & Plunkett, G.M. (2012) Untangling generic limits in Azorella, Laretia, and Mulinum (Apiaceae: Azorelloideae): Insights from phylogenetics and biogeography, Taxon, 61(4): 826-840(15). Abstract. This has yet to be resolved.
