Sheaths ovate, dark castaneous;
Blades linear, attenuate, to 36 mm wide, bearing a pale median channel.
Scape erect, elongate; lower scape-bracts foliaceous, the upper lanceolate, acuminate, usually exceeding the internodes.
Inflorescence simple, usually long and cylindric, glabrous or furfuraceous; rhachis black or pale when dry.
Floral bracts lanceolate or narrowly triangular, the lower ones usually equaling or exceeding the pedicels;
Flowers suberect to spreading;
Pedicels slender, 8-25(-35) mm long.
Sepals narrowly triangular, 22-28 mm long;
Petals acute, 5-6 cm long, naked, red;

Key to the Varieties of Pitcairnia flammea
Leaf blades spiny at base - var spinulosa
Leaf blades entire:
1. Leaf-blades covered beneath with spreading scales, mostly 20-36 mm wide.
- 2. Axis of the inflorescence glabrous, usually turning black on drying. - var flammea.
- 2. Axis of the inflorescence lepidote, usually remaining pale. - var roezlii.
1. Leaf-blades glabrous or, if lepidote, always less than 20 mm wide; inflorescence remaining pale
- 3. Axis of the inflorescence glabrous; leaf-blades glabrous.
- - 4. Inflorescence lax, few-flowered. - var corcovadensis. NOW species in own right
- - 4. Inflorescence dense, at least toward apex, many-flowered.
- - - 5. Petals red - var glabrior.
- - - 5. Petals yellowish white. - var pallida.
- 3. Axis of the inflorescence lepidote.
- - - 6. Floral bracts equaling or exceeding the lower pedicels. - var floccosa.
- - - 6. Floral bracts shorter than the lower pedicels; pedicels to 35 mm long. var macropoda.

Pitcairnia flammea Lindley var spinulosa
Habitat: Brasil, Estado de Minas Gerais, Serra do Cipo.
"P. flammea is a very variable species, six varieties having been described already. In revising the specimens of Pitcairnia from the herbarium of the. Museu Botanico Municipal of Curitiba, Parana, I found this plant on which I did not find enough characters to establish a new species however the clearly spinose margins of the basal portion of the leaves permit to separate it at least as a new variety. With more and better specimens available perhaps other characters can be found which will permit to separate this taxon as a distinct species."
