...For example, arils are present in the two earlier-diverging clades of the genus (Stull et al. 2017) and could be energetically more costly for the plant than the sarcotestas that predominate in more recently diverging clades....

...Four species within the X. acutiflora group were included in the molecular phylogenetic analysis of the genus by Stull et al. (2017), and all fell within a strongly supported clade along with several Madagascar species....

...Unit D was not further subdivided as phylogenetic data indicate that Indian and Australian species in several genera are likely derived from other Asian taxa (e.g. Artabotrys, Huberantha: Thomas et al., 2015; Meiogyne: Thomas et al., 2012b; Pseuduvaria: Su & Saunders, 2009; Uvaria: Zhou, Su, Thomas, & Saunders, 2012; Xylopia: Stull et al., 2017), and previous divergence time estimates indicate that likely none of these represent Gondwanan relictual lineages which originated in situ and rafted to Asia on the Indian or Australia fragments (e.g. Couvreur et al., 2011; Thomas et al., 2015)....

...We used an Akaike information criterion (AIC) test (Akaike 1974) to select among three different transition models for the reconstruction: 1) equal rates model, 2) equal forward/reverse transition rates model, and an all-ratesdifferent (ARD) model; in all cases the ARD model was identified as the…...
