 | | The Heliantheae constitute a very large tribe of Asteraceae with 24 subtribes recognized in the Flora of North America (2006). |
| | Nearly all of the species in 7 of the 10 subtribes illustrated here may be readily recognized due to the association of a receptacular bract or chaff scale with each disk floret in the head (Chaenactinidae, Gaillardiinae, and Pectidinae, mostly lack true chaff scales). |
| | The well-known Hawaiian silversword evolved from members of Heliantheae that are found on the west coast of North America. |
