Both Buddleja and Acantholimon are considered which level of classification?
Acantholimon Acantholimon (prickly thrift) is a genus of small flowering plants within the plumbago or leadwort family, Plumbaginaceae. They are distributed from southeastern Europe to central Asia and also in South America, but also cultivated elsewhere in rock gardens.
Ginger-families The ginger-families or ginger group or Core Zingiberales is a terminal clade in the order Zingiberales (:Monocotyledoneae) that comprises Zingiberaceae (the ginger family), Costaceae, Marantaceae and Cannaceae. Their shared synapomorphy of a single fertile anther and four or five highly modified staminodia differentiate them from the basal paraphyletic assemblage of the "banana-families".
