|Kingdom||Plantae||Plants, but not fungi, lichens, or algae|
|Subkingdom||Tracheobionta||Vascular plants—plants with a “circulatory system” for delivering water and nutrients|
|Division||Magnoliophyta||Flowering plants, also known as angiosperms|
|Class||Magnoliopsida||Dicotyledons—plants with two initial seed leaves|
|Subclass||Asteridae||A large class that encompasses asters|
|Order||Asterales||Flowering plants with a central disk flower and surrounding petals, like daisies|
|Family||Asteraceae||The aster family, which also includes daisies and sunflowers; from the Greek ἀστήρ, “star,” for the star-shaped flowers|
|Genus||Ratibida||A name used by C.S. Rafinesque. David Hollombe sent me the following: “Rafinesque’s brief description in a paper in ‘Journal de physique, de chimie et d’histoire naturelle et des arts’ in 1819 mentions the rays as being bifid, although that explanation does not account for the ‘t’.” Rafinesque often assigned unexplained names to plants. It is curious that about 60 sites online use the spelling Ratidiba rather than Ratibida|
|Species||columnifera||Bearing columns, in reference to the tall cylindrical flower heads|
