'''''Castilleja''''' is a [[genus]] of about 200 species of [[Annual plant|annual]] and [[Perennial plant|perennial]] [[herb]]aceous [[plant]]s native to the west of [[the Americas]] from [[Alaska]] south to the [[Andes]], as well as northeast [[Asia]]. Formerly classified in the family [[Scrophulariaceae]], they have recently been relegated to the family [[Orobanchaceae]] as a consequence of [[molecular systematics]] research (see [[Angiosperm Phylogeny Group]]). They are commonly known as '''Indian paintbrush''' or '''Prairie-fire'''. They are semi-[[Parasitic plant|parasitic]] on the roots of grasses.

''Castilleja'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including ''[[Schinia|Schinia cupes]]'' (which has been recorded on ''C. exserta'') and ''[[Schinia|Schinia pulchripennis]]'' (which feeds exclusively on ''C. exserta''). Also checkerspot butterflies such as ''Euphydryas''.

One of the species of this genus, '''Indian paintbrush''' (''Castilleja linariaefolia'' <ref>Wyoming Statute 8-3-104 [http://legisweb.state.wy.us/statutes/statutes.aspx?file=titles/Title8/Title8.htm (Title 8)]</ref>) was adopted on [[January 31]], [[1917]] as the state flower of [[Wyoming]].
