They foreshadowed publishing a full arrangement once DNA sampling of Dryandra was complete; in the meantime, if Mast and Thiele's nomenclatural changes are taken as an interim arrangement, then B. marginata is placed in B. subg. Spathulatae.
The researchers anticipate releasing a full classification once DNA samples from Dryandra are analyzed. Until then, if Mast and Thiele's proposed changes are used as a temporary arrangement, *B. marginata* would be categorized under *B. subg. Spathulatae*.
