Agathosma [SEP] parent taxon
Agathosma
Agathosma is a genus of about 140 species of flowering plants in the family Rutaceae, native to the southern part of Africa. Common names include Buchu, Boegoe, Bucco, Bookoo and Diosma.

They are small shrubs and subshrubs, mostly with erect woody stems reaching 30–100 cm tall, but low-growing

This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
