Are both Calibanus and Euphorbia members of the Euphorbiaceae family?
Calibanus Calibanus is a genus of two species of flowering plants, both evergreen succulents from dry areas of northeastern Mexico. The APG III classification system places it in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae. ) It was formerly included in the Agavaceae (now Agavoideae) but is now separated from them, for it is polycarpic and dioecious. Its name refers to the monster Caliban, an antagonist in Shakespeare's "The Tempest".
Calothamnus Calothamnus is a genus of shrubs in the family Myrtaceae and is endemic to the south-west of Western Australia. The common names one-sided bottlebrush or claw flower are given to some species due to their having the flowers clustered on one side of the stem or because of the claw-like appearance of their flowers. "Calothamnus" species are generally medium to tall woody shrubs with crowded leaves. In most species the leaves are crowded and linear in shape, and the flowers are usually arranged in dense clusters. The petals are small and fall off the flower soon after it opens but the stamens are long, numerous and usually bright red.
