Pyrolirion, commonly known as fire lilies or flame lilies, is a small genus of herbaceous, bulb-forming South American plants in the Amaryllis family, native to Chile, Peru, and Bolivia.[3][4]

Description

[edit]

Pyrolirion have 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 to 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

[edit]

The genus Pyrolirion was first established by the British botanist William Herbert in 1837.[6] The name Pyrolirion is from Greek πῦρ (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]

Pyrolirion is classified under the tribe Eustephieae of the subfamily Amaryllidoideae, family Amaryllidaceae. It was previously sometimes considered by some authors as a subgenus of Zephyranthes (rain lilies), but DNA sequencing has shown that it is a distinct genus more closely related to the genera Chlidanthus, Eustephia, and Hieronymiella in the tribe Eustephieae than to members of the tribe Hippeastreae.[9][10]

Species

The species-level classification of Pyrolirion is unclear and in need of further study. The following are accepted at present (April 2015)[2][11][12]

  1. Pyrolirion albicans Herb. - Perú (Arequipa)
  2. Pyrolirion arvense (F.Dietr.) - Perú (Cusco, Lima)
  3. Pyrolirion boliviense (Baker) Sealy - Bolivia (Cochabamba, La Paz)
  4. Pyrolirion cutleri (Cárdenas) Ravenna - Bolivia (Cochabamba)
  5. Pyrolirion flavum Herb. - Perú (Cusco, Lima)
  6. Pyrolirion huantae Ravenna - Perú
  7. Pyrolirion tarahuasicum Ravenna - Perú
  8. Pyrolirion tubiflorum (L'Hér.) M.Roem. - Perú, Chile
