acroclinium
/ˌakrə(ʊ)ˈklɪnɪəm/noun
A plant of the former genus Acroclinium (now included in Rhodanthe), of the family Asteraceae (Compositae), which comprises herbaceous annuals native chiefly to Australia; especially a plant of one of the numerous cultivated varieties grown widely for their persistent flowers (everlastings), which are typically red, pink or white, and often used dried in arrangements. Also (in form Acroclinium): the former genus itself.
Origin
Mid 19th century; earliest use found in Hooker's Journal Botany. From scientific Latin Acroclinium, genus name from acro- + ancient Greek κλίνη couch + classical Latin -ium, so called on account of the acutely conical receptacle.
