Are Burretiokentia and Rebutia both types of plants?
Burretiokentia Burretiokentia is a genus of palms (Arecaceae) endemic to New Caledonia containing five species. The relationships between Burretiokentia and some other genera of the tribe Basseliniinae including "Physokentia" and the New Caledonia endemic "Cyphophoenix" are not clear.
Metrosideros Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the Myrtaceae family. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek "metra" or "heartwood" and "sideron" or "iron". Perhaps the best-known species are the pōhutukawa ("M. excelsa"), northern rātā ("M. robusta"), and southern rātā ("M. umbellata") of New Zealand, and "ʻ ōhiʻ a lehua", ("M. polymorpha"), from the Hawaiian Islands.
