Are Copiapoa and Lophospermum both cacti?
Copiapoa Copiapoa is a genus of cacti from the dry coastal deserts, particularly the Atacama Desert, of northern Chile. It comprises about 26 species. These species vary in form from spherical to slightly columnar and in color from a brownish to blue-green body.
Callococcus Callococcus is a genus of Australian scale insect that feeds on species of "Leptospermum", "Hypocalymma", "Kunzea" and some other members of the tribes Chamelaucieae and in the myrtle family Myrtaceae. "Callococcus leptospermi" induces stem-swelling galls on some species of "Leptospermum", and it is considered to be a potential biological control agent of "Leptospermum laevigatum" in South Africa. The other described species of "Callococcus" do not induce galls.
