Achyranthes arborescens R.Br.

"GBIF Backbone Taxonomy (exact match; species key 3672788) accepts Achyranthes arborescens R.Br. with status ACCEPTED, family Amaranthaceae, and the same species placement as POWO/Kew, which records Centrostachys arborescens (R.Br.) Standl. as a homotypic synonym and the species as native only to Norfolk Island. The species-specific Flora of Australia reference (Green, en Barrett y Kodela, eds.) and the Australian Government conservation advice document the soft-wooded tree of up to 9 m, its terminal spikes, November–March flowering, and preference for moist forests and streams. The official TSSC advice recommends Critically Endangered under the EPBC Act: it records 57 mature individuals and an extent of occurrence of 2.3 ha; threats include habitat loss and degradation, grazing, rats, invasive weeds, drought, and cyclones. An official recovery plan reports low germination (approximately 5%) and favourable propagation by cuttings. No species-specific uses, toxicity, pathogens, companion plants, pH, or cultivation substrate were verified.
