Coronidium elatum
''Coronidium elatum'', commonly known as the white paper daisy or tall everlasting, is a perennial herbaceous shrub in the family Asteraceae found in open forests in eastern Australia. A woody shrub tall, it has white flowers which appear in spring. It was known as ''Helichrysum elatum'' for many years until it was finally reviewed in 2008.
==Taxonomy==
The tall everlasting was collected by the English botanist and explorer Allan Cunningham and described by him in Augustin Pyramus de Candolle's 1838 work ''Prodromus Systematis Naturalis Regni Vegetabilis'' as ''Helichrysum elatum'', the species name being the Latin adjective ''elatus'' "tall". The large genus ''Helichrysum'' was long recognised as polyphyletic and many of its members have been transferred to new genera. Botanist Paul G. Wilson erected the new genus ''Coronidium'' for 17 species of daisy of the eastern states of Australia,〔 and it was given its new name of ''C. elatum'' in 2008. Three subspecies are recognised, two of which are highly restricted in distribution. Subspecies ''vellerosum'' is found on the summit of Mount Warning and is more woolly-leaved and reaches a height of , and subspecies ''minus'' is found only at Point Lookout in New England National Park. Reaching 80 cm high, it has smaller and thinner leaves than the nominate subspecies.〔
