Pyrolirion has thin linear leaves that may be pointed at the tips. The flowers, which can vary in coloration, are borne erect on solitary hollow scapes. The perigone is funnel-shaped, with a cylindrical tube that flares out abruptly into star-like radially arranged (actinomorphic) petals. Small scale-like "paraperigone" may be present at the base.[5]
The stamens arise from or below the throat. The style has three branches at the tip with spoon-shaped (spatulate) stigmas. The seeds are laterally compressed, colored black with white seams (raphe).[5]
Systematics
The genus Pyrolirion was first established by the BritishbotanistWilliam Herbert in 1837.[6] The name Pyrolirion is from Greekπῦρ (pyr, "fire") and λείριον (leirion, "lily"). It is named after the flame-like colors of the flowers of Pyrolirion arvense (the golden flame lily).[7][8]
