Many studies have shown that Severinia buxifolia is clustered within the Atalantia clade in the molecular phylogenies (Bayer et al., 2009; Penjor et al., 2010, 2013; Schwartz et al., 2016; Nagano et al., 2018).
Therefore, I think the treatment in POWO and its reference (the Asian Floras and checklist) is appropriate.
I have committed the taxon swap.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
