Are Copiapoa and Lophospermum both cacti?
Lophospermum Lophospermum is a genus of herbaceous perennial climbers or scramblers, native to mountainous regions of Mexico and Guatemala. Those that climb use twining leaf stalks. Their flowers are tubular, in shades of red, violet and purple, the larger flowers being pollinated by hummingbirds. Now placed in the greatly expanded family Plantaginaceae, the genus was traditionally placed in the Scrophulariaceae. The close relationship with some other genera, particularly "Maurandya" and "Rhodochiton", has led to confusion over the names of some species.
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.
